With many mobile phone manufacturers increasing the running memory of their phones to 12G or even 16G, the problem of killing the background has once again become a hot spot. Is it really necessary to kill the background of a mobile phone with such a large memory? In fact, it’s not just users who have a headache for this, but also software developers and Android developer Google.

Recently, Google officially launched an investigation into the background killing of third-party customized systems. It is hoped that software developers can provide relevant information to them. After collecting the information, they will find the person in charge of the relevant system and discuss how to make users’ The experience is better guaranteed.

Why did Google shoot?

For Google, the problem of killing the background is actually not the Android system, but a series of background management mechanisms developed by major custom system manufacturers according to their own needs.

At least as far as the Android system itself is concerned, they are not strict in controlling the backend of the system. According to the design of the native version of Android released by Google, only after the system has recovered all the cache and found that it is still insufficient to provide enough memory to maintain the smooth operation of the system and new apps, will it start to force some apps to close according to the opening sequence. The memory they occupy is recycled.

In the near future, it may be that the complaints of developers have finally accumulated to a certain extent, and Google has also decided to stand up and give some responses. In addition, The back-end management mechanism of some customized system vendors may also violate some Google terms.

According to public documents, as early as 2018, developers on the AOSP (Android Open Source Project) had already submitted documents about custom system vendors abusing Android core permissions and imposing strict background control mechanisms, and received a lot of documents. Developer support. At the same time, some developers who are committed to developing accessibility apps that provide assistance to special people are also very bitter in the document, saying that they have developed an accessibility service app, which has been blocked on many systems for background operation permissions, allowing users to use it. The special people of this app cannot get the services they deserve. For some visually impaired users, they need to use some accessibility software to help them control the phone without others.through Normally, similar accessibility software runs silently in the background, and when their accessibility software is killed in the background, it will be difficult for these users to open the software again. From this point of view, the harsh back-office killing mechanism does affect a group of users. For ordinary users, they may just lose the pages they browsed before. For these special people, it may become a part of their lives. big trouble. Now that Google intends to control and kill the back-end problems, what does Google intend to do? At least, Google has not publicly stated what restrictions or requirements it intends to make on the issue of killing the background, but has initiated a series of investigation procedures, such as asking affected developers to provide the following details: The name of the affected application The name of the OEM and device model they observed the problem Android operating system version Steps to reproduce the problem, as well as expected and observed results Affected API Can they reproduce the same problem on Pixel devices (or other devices running the same Android version). Google’s efforts to control and kill the background problem may be a good thing for some users, but from the point of view of all users, it may not be harmless. Is it right to kill the backstage? I think everyone should know the answer to this question. The reason why the system kills the background is very simple. It is to ensure the fluency of the system and the software currently in use. In the past few years, the problem of the system background was a headache for domestic Android phone users. However, the headache at the time was not that the backstage was killed, but the backstage was inexhaustible. At that time, Android mobile phone manufacturers did not control the background as strict as they are today. Although they also gave restrictions to a certain extent, they were useless in the eyes of domestic App developers. What is even more annoying is that many apps at the time not only had to stay in the background, but also associated wake-ups after being woken up, starting a series of apps that the user did not click on and letting them stay in the background. It is precisely because of these problems that Android users at that time almost regarded flashing as a necessary skill, because only after obtaining the ROOT permission of the system can they install the background control App, and kill all the software that has been resident and self-starting, and return to the system. One smooth. However, it is precisely because of the unscrupulous background staying and self-starting of domestic apps that domestic custom system manufacturers can only always strengthen the background management mechanism. Similarly, other overseas mobile phone manufacturers that have market layouts in the country are the same, and they have even arrived. To the extent that it is better to kill by mistake than to let it go. Except for a part of the key software on record, such as WeChat, QQ, etc., will be retained by the system, and the rest of the software will be killed unless the user adds the software to the whitelist in advance. However, for most users, they are not inclined to actively add software to the whitelist, and many users are not even aware of the existence of the whitelist. As a result, some apps that need to stay in the background to provide services for a long time have to actively guide users to add the App to the whitelist on the setting page. For example, for some apps that are connected to smart wearable devices, in order to be able to feedback user operations and record data at any time, these apps must reside in the background. So if you often hear people complaining that your smartwatch is always not working, then it is probably related to killing the background. In addition, in terms of back-end control, the most stringent ones are probably MIUI and Sony. Among them, the problem of MIUI’s back-office killing has been raging some time ago. At the same time, the official also responded, saying that the back-end mechanism will be adjusted. In fact, the problem of MIUI killing the background is mainly derived from the flares function introduced after the last update. This function is mainly aimed at the problem of frequent self-starting of the software, hoping to make the user’s system smoother. The flares function is mainly aimed at the problem that the App can request user permissions and information without a lower limit. It returns blank information and permissions in a targeted manner. The original intention is not to prevent the software from launching. However, there are many softwares in China that use the method of setting the service as a sticky service on the self-starting and resident background. And service is the area that the flares will focus on, so many softwares are blocked by the flares to stay in the background. After the user shrinks them, they are quickly killed by the system. The other part of the App uses the parent-child process. This part of the software is not within the limit of the flares function, so it can stay in the background for a period of time. This is why the background killing problem of MIUI 12 only appears on some software. . However, follow-up Google and MIUI responded to the developer’s troubles, saying that they will modify the relevant mechanisms to ensure the normal use of the software. In any case, the original intention of the system to kill the background is to allow users to use the phone normally, but if this mechanism is too strict, it will in turn affect the normal use of the user, which is indeed a dilemma. If you want to make the back-end management mechanism more reasonable, you need not only the efforts of custom system vendors and Google, but also the responsibility of software developers. After all, if it is not for software developers to keep self-starting and forcibly staying for benefits The background will not make the system manufacturer’s background control mechanism more stringent. At last At least for now, a strict background mechanism is still necessary, especially on some mobile phones with small running memory. If the software is allowed to reside and associate itself, I am afraid it will really not work properly. However, on mobile phones with 12G or higher running memory, you may consider relaxing the background management to make the user’s multi-App experience better. On the other hand, it still depends on whether Google can make a major change to Android’s background management. If it can imitate Apple to design a similar mechanism, then the background problem can be better solved. Because Apple’s iOS system does not actually have a background, the reason why the App on the iPhone can return to the state just before it was closed after re-waking up is actually because the iOS system retains a snapshot of the information when it is closed, and the App returns When you arrive at the front desk, you can restore it to its previous state based on the snapshot. This mechanism is called a “tombstone”, which is quite vivid. However, if you want to implement the tombstone mechanism on Android, the difficulty may be quite large. Finally, Xiao Lei would like to ask: What do you think about the issue of killing the backstage?

However, in Apple’s ideal state, AirTag is used for items such as backpacks, keys, and bicycles, not for people and pets. But in practice, AirTag not only can “recover” lost items, it may also become a cheap and convenient tracker.

Android users are more easily tracked by AirTag

AirTag uses low-power Bluetooth to connect, and the ultra-wideband U1 chip is used for positioning and pointing. It can easily find the items tied to the AirTag.

If the AirTag leaves your “line of sight”, it will broadcast to surrounding Apple devices such as iPhones and Macs, and upload it to the cloud anonymously, so that you can see the movement trajectory and approximate location of this AirTag.

This is probably the operating principle of AirTag. The equipment is simple and the principle is not complicated, but the rule logic may be more important. From its release to the present, AirTag’s firmware has been upgraded in a round. What the new firmware (version number is 1.0.276) is not to improve performance and add new functions, but to focus on optimizing security. In the past, AirTag left its owner and moved its location. It would only play a sound after three days to remind people around. AirTag’s “three-day” timer will be reset when it is close to the “master”, this loophole may be exploited by people with intentions. AirTag’s new firmware revised the “three days” period to a random reminder within 8 to 24 hours to avoid malicious tracking between intimate relationships. In addition, when the iPhone finds that there is an unfamiliar AirTag nearby, there will be a corresponding pop-up notification, but Android devices do not have such a reminder (or warning). Therefore, relatively speaking, Android users are more likely to be “secretly” tracked. For this, Apple is also developing an Android application that allows Android users to quickly and easily detect AirTag or accessories based on the “find” network function. The AirTag for Android application is expected to be launched by the end of the year. AirTag is a very simple object, and Apple’s purpose is also very simple, which is to use a huge “find” network to “anti-lost”. But some of the rules are not thoughtful enough, and there are still some loopholes that can be exploited, making it a product that has both good and evil. AirTags are a smart and adjustable “ecology” In May of this year, Geoffrey A. Fowler, author of the “Washington Post” technical column, wrote an article criticizing AirTag for not doing enough “anti-tracking”. Through simulation experiments, he and his colleagues showed that it is easy for people with interest to bypass AirTag’s anti-tracking measures. Even if Apple upgrades the AirTag firmware, the warning sound is no longer a fixed time, but the time will be reset after contacting the owner’s iPhone. Therefore, if the tracker and the tracked live together, the AirTag’s warning sound may never Will be activated. So far, Android users are still unable to distinguish well whether there are maliciously placed AirTags around them. “This is a potential threat to 50% of Android users in the United States.” In addition, the warning sound emitted by AirTag lasts only 15 seconds, the volume is 60 decibels, and then it is silent. And Jeffrey Fowler also found that when the top of the AirTag receives pressure, the warning sound will become smaller or even disappear. After these vulnerabilities in AirTag were discovered, in addition to blocking the loopholes in the functional rules, Apple’s vice president of marketing Kaiann Drance told The Washington Post that AirTag, which cooperates with Apple’s “Find” network, is a set of “active Threat measures” are intelligent and adjustable systems. “We can continuously improve the operating logic and rules behind them to promote this system to become better.” ▲ Kaiann Drance, Apple’s vice president of marketing. And now, Apple is constantly making adjustments and improvements. The new firmware may be just the first step. After the Android application goes online, the anti-lost rules may be more stringent. However, Bluetooth anti-lost devices such as AirTag are not Apple’s first, and the way to use online devices to help find is not an idea from Apple, but the special feature of AirTag is that it relies on the “ecology” that Apple has built over more than ten years. The engineer at Apple Park knocked down a line of code and the OTA on the device will quietly change the way your device operates. The same is true for the small AirTag. This may be what Kai An, Apple’s vice president of marketing, said “smart, smart, Adjustable system”. Compared to traditional Bluetooth anti-lost devices such as Tile, Apple has done more to prevent tracking behavior, and Tile has not taken action to prevent tracking. But AirTag, which has received much attention at present, shows that even Apple, which pays great attention to user privacy and device security, has failed to consider all the risks brought by new technologies and is still in the groping stage. The old-fashioned double-edged sword problem In response to AirTag’s approach to the owner’s reset of the warning time loopholes, Corbin Streett, a security expert at the American Organization for the Elimination of Domestic Violence, told Macrumors, “The tracking threat pattern generated between intimate relationships is unique and Not universally. For the average company, the general concern is external threats, not the people sleeping next to you.” Moreover, this kind of incident is quite special, it is difficult to distinguish and distinguish by machine through rules, and whether it is too strict for the small AirTag to bear too much “right and wrong”, after all, the technology itself is not wrong, the wrong is the human heart. This is like the mother box in the DC universe. In the hands of Darkside, it is the strongest weapon in the universe. In the hands of the Justice League, it can resurrect Superman. ▲ The walking supercomputer “steel bone”. Just as the steel frame said, “The mother box is a modified machine. The mother box does not have the concept of killing, dying, alive, or saving people. They rearrange the material according to the owner’s wishes to regenerate and restore the original state.” Before the appearance of Bluetooth anti-lost device, there was no such discussion about “anti-tracking”. Apple, standing in the center of the world’s science and technology, naturally has a high degree of attention. Every product is born under the spotlight. The same is true for AirTag. Naturally, there will be endless positive and negative discussions about it. From now on, for AirTag, Apple’s earliest layout is actually the U1 chip integrated with UWB technology on the iPhone 11. Compared with common communication technologies such as Bluetooth and WiFi in the industry, UWB technology is mainly used for short-distance precise connection and data transmission. Previously, the iPhone equipped with the U1 chip can be quickly paired with a Mac or iPad, and data can be transferred via AirDrop. The emergence of AirTag is the landing of U1 chip and UWB technology in short-distance precise positioning technology, and the “find” network is an extension. If predicted, U1 chip, UWB technology, AirTag, and the current spatial audio are all Apple’s layout in the AR field. This should be one of Apple’s goals for launching AirTag. In fact, before the advent of AirTag, if you want to track maliciously, you can also buy trackers based on GPS and LTE on Amazon. After the emergence of AirTag, there is nothing more than an additional channel for these interested people. ▲ GPS tracker on Amazon. Fire can start a prairie fire, or it can bring warmth. The same is true for AirTag. In some people, AirTag may be a very good tool for finding objects, while in others, AirTag is a tracker. Even if Apple continues to upgrade and improve the rules, they can always find loopholes in these rules to conduct illegal actions. It’s just that when Apple releases AirTag, if it can simultaneously release an application for the Android platform to cater for more user groups, it may be more humane and thoughtful. #Welcome to follow Aifaner’s official WeChat account: Aifaner (WeChat ID: ifanr), more exciting content will be provided to you as soon as possible. | · ·

The newest Beats member shows the direction of Apple for its two line of headphones. Studio Buds are cheaper and more compatible than AirPods. It can be charged via the universal USB C connection instead of the proprietary Lightning charging port. It also has its own Android app for those outside the iOS ecosystem. If AirPods are intended to complement and enhance the experience of using iPhone, iPad, and Mac, Beats products are aimed at a larger, more diverse market. Apple wants to turn AirPods into a more premium product when it introduces the AirPods Max hooded headset, equipped with the Spatial Audio feature to increase the difference. Beats Studio Buds allows Android users to see the exact amount of battery on each headset as well as the included charging case. The headset can also be controlled using the Google Assistant. The accessory’s minimalist design also marks a change for Apple. According to testing by Bloomberg, the compact design of the headset makes it comfortable to wear for a long time. It has a noise reduction mode, which is not too effective when listening on a noisy street, but also supports the user experience. The headset battery lasts 8 hours on a single charge, but only when noise cancellation is not activated. Beats Studio Buds for ordering now and starting to ship from June 24. The headset has three colors red, black and white, priced at 3.44 million. Du Lam (According to Bloomberg)

Apple is expanding Facetime On the way to the digital campfire

Status: 08.06.2021 7:46 p.m.

Apple renews its Facetime app. The group is not only reacting to competition from providers such as Zoom, but is also opening up to Windows and Android devices. From Marcus Schuler, ARD studio Los Angeles Apple is slowly opening up to Android and Windows devices with its video chat service Facetime. It’s almost a small revolution – at least by Apple standards. Software boss Craig Federighi sold the news as follows: “Not only Apple devices can do something with the Facetime link. Users with Android or Windows can also open it directly in their browser and take part in the chat.” So far, Apple has struggled when it came to opening up core functionalities on its iPhone or desktop computers. But the popularity of video chat services like Zoom has exploded in the Corona crisis. Apple reacts precisely to this development and has given its Facetime app a fundamental facelift.

Competition for Zoom

From there, you can send links to friends with Android phones or Windows computers in order to meet with them in the Facetime chat. Marc Gurman, an analyst at the Bloomberg business service, says Apple is primarily competing with Zoom. Among other things, with scheduling and improved sound and picture quality. The new Facetime app is supposed to deliver a bit of a digital campfire. With the help of the app, you will be able to listen to music and watch videos together in the future without interrupting the chat. It should be possible to watch programs together with friends. Ambient noises should be better suppressed in the chat app. There will also be a portrait mode that blurs the background.

More control and more data protection as an issue

The second big innovation on Apple’s smartphones concerns the notification functions. They give users more control over how and when they want to be disturbed or undisturbed. “There are new features with which you can adapt the notifications to different activities. For example, while you are working or want to be undisturbed,” says analyst Gurman. Data protection and privacy have been playing an increasingly important role at Apple for the past three years. The Californian company is trying to sharpen its profile in order to differentiate itself more strongly from its competitor Google and its Android system. So-called tracking pixels are now blocked in the Group’s mail app. Advertisers and marketing people are likely to be annoyed with Apple again. You can no longer check whether and where an e-mail has been opened.

This malicious application is called Mods Minecraft. The app doesn’t function like an ad at all, instead it turns the victim’s smartphone and tablet into an ad-player in an extremely sophisticated way. (Photo: Kaspersky) Accordingly, after the first run, the application will hide its icons from the screen and continuously open the browser to display ads. The app can also play videos from YouTube, access the Google Play app store, and more. Security experts at Kaspersky found that the app opens the browser every two minutes, rendering the device essentially inoperable. use to be. (Photo: Kaspersky) What’s especially worrisome is that it’s hard for users to know what’s going on with their devices, which apps are responsible for the trouble, and how to prevent it. The security experts at Kaspersky informed Google of their findings and the malicious app was quickly removed from the store. Minecraft is one of the best-selling games in the world with about 180 million copies worldwide. (Photo: Mojang) However, removing this app from Google’s app store does not mean the removal of all malware. In the past, developers of this type would simply upload new, slightly modified versions, using different names, from different developer accounts to further trick victims. An example can be mentioned is the VK Music Trojan. This app stole VK user accounts, but despite being reported, the app has survived on the Google Play app store for several years. (Artwork: Unsplash) Kaspersky ran a search for malicious Minecraft Mods-like apps – and found a few. In addition to the malicious application Mods Minecraft, a utility called File Recovery was also found to contain malware in version 1.1. However, that version has since been removed and version 1.1.1 of the app, available on Google Play, is safe.

But at this moment, don’t forget Lei Jun, the founder of Xiaomi and also the chairman of Jinshan. Jinshan’s WPS is the first batch of software adapted to Hongmeng. What’s so great! What’s the use of showing such a sincerity without software!” A voice like this came out again.······

WPS is not ordinary software, it is the first Chinese office software. WPS is also the only office software on the market that can break the wrist with office. For ordinary people, wps can be said to be free, it does not cost to buy, and the basic functions are enough. At the same time there are Linux and Mac versions, and the scope of application is very wide!

It essentially has the same innovative spirit as the Hongmeng system, the spirit of external resistance and anti-monopoly. He is a domestic software with completely independent intellectual property rights. It is independent in the true sense and is also one of the pride of domestic software. Jin Yong’s novels swept the country in the 1980s. At that time, programmers all harbored a kind of chivalrous spirit in martial arts novels, a person, a sword, and a little prosperous. They also believe that a single person and a computer can raise the banner of domestic software development and work tirelessly for it. Qiu Bojun, the founder of Wps, is such a person.

WPS for DOS

From May 1988 to September 1989, for more than a year, Qiu Bojun locked himself in the room and typed codes every day, during which he was hospitalized three times due to hepatitis. It took hundreds of thousands of lines of code to create the first word processing system WPS 1.0. From that day on, he looked forward to WPS becoming the mainstream word processing software in the Chinese market. At that time, there was very little network communication between China and the outside world, and there was no access to the Internet. Therefore, as soon as WPS came out, it quickly swept the domestic market at that time. In the late 1980s before computers became popular, WPS sold more than 30,000 sets at a price of 2,200 yuan. At the same time, it has become the most well-known software in the country.

Qiu Bojun later went to Zhuhai and founded Zhuhai Jinshan Computer Company, which was also the predecessor of Jinshan Software. After several years of hard work, Wps has a huge market share. Many software parks that came here have joined Jinshan, saying that Jinshan was the Whampoa Military Academy of China’s software industry at that time. It is not too much to say that at that time Lei Jun joined Jinshan.

In a blink of an eye, it came to 1993, and Microsoft, looking for overseas markets, couldn’t wait to come to China to share a piece of cake. Microsoft’s astuteness is that it binds word5.0 to the Windows operating system, and word5.0 is automatically pre-installed when Windows is installed. In order to correspond to this set of Microsoft’s combination punches, Qiu Bojun and Lei Jun are based on the Windows operating system The forecast of the system developed Pangu components similar to today’s office. Pangu components can be said to have exhausted all the financial and material resources of Jinshan Company, and it took three years for Pangu components to finally go on the market.

But only more than 2,000 sets of Kingsoft were sold. Even more frightening is that the original WPS market has shrunk sharply under the attack of piracy. In the case of piracy and Microsoft, WPS once left only 4 programmers, and even Lei Jun wanted to leave. At this time, the old rival Microsoft Office suddenly came to seek cooperation. I want to communicate the agreement between office and WPS. Simply put, users of two people can open the documents of each other’s products at any time. Is it a gift in the snow or a weasel to a rooster?

All wrong, Microsoft has come to a trick to boil the frog in warm water. Since the two software can communicate with each other, there is no bottleneck. Office has expanded rapidly with the popularity of Windows97, slowly eroding the remaining market share of wps. In China at that time, piracy was rampant, there were more and more pirated systems, and more and more offices. Finally, office occupied more and more Chinese market. It almost monopolizes the domestic office software market.

Watching WPS decline step by step. Microsoft made several requests for the acquisition of Kingsoft and even fired Qiu Bojun an annual salary of 750,000 yuan, but Qiu Bojun refused. In the end, Qiu Bojun sold his villa in Zhuhai for 2 million and continued the development of WPS. It was this feeling that drove Qiu Bojun to lead the development team to work 12 hours a day for 365 days and finally developed WPS97. Although the development was successful, the WPS at this time was still somewhat inadequate compared to the word at the time, and even the WPS developers did not have much confidence.

But what they didn’t expect was that only two months after the launch of WPS97, 10,000 sets were sold under a large number of government school purchases. (The earliest text editing software I learned in elementary school was WPS97) This brought WPS back to the competition platform with Microsoft. In order to compete, Kingsoft and Microsoft started a price war. In 1999, the “Red Genuine Storm” led by Lei Jun set WPS2000 at 28 yuan, which at that time was equivalent to the price of cabbage for genuine software.

It can be said that the piracy problem that even Microsoft didn’t solve was solved by Lei Jun. However, what Kingsoft never expected was that Microsoft actually allowed the rampant piracy. In 2002, it unilaterally tore up the agreement and subtracted the WPS compatible conversion mode, leaving users to choose one of the two. This brought Kingsoft again. Heavy blow.

Red genuine storm

But who is Lei Jun? Lei Jun was stunned to overthrow the WPS with certain sales volume and redo it. Under the pressure of office, Lei Jun decided to rewrite the wps according to the office’s usage habits, which also made WPS lose the reputation of plagiarism. After obtaining the consent of the founder Qiu Bojun, Lei Jun immediately began to implement this plan after spending a lot of manpower and material resources.

As the leading domestic technology and technology company, Lei Jun has a wide range of knowledge. Recently, it has been reported that Lei Jun wants to enter a new field and wants to acquire Anmaotong APP, which has a lot of friends, from thousands of dollars of sports shoes such as Adinike to major fashion brands. , And then to the famous watches such as LV Rolex, which cost tens of thousands of yuan, it is actually less than 100 yuan on the Anmaotong APP.

On the market, AJ, which was fired at tens of thousands of yuan, and coconut 350, which was sold at thousands of yuan, were sold out 10 blocks by AnyTrade. In just half a year, the Anmaotong APP created a storm in the trend circle of first- and second-tier cities, and young people born in the 90s and 80s are planting grass. Is Xiaomi going to start a new round of e-commerce competition?

In 2005, the new version of wps was launched, and it quickly caught up with office by the wind of the Internet, and even caught up with and surpassed the mobile Internet. Microsoft’s triumphant Hutong project before was used by Lei Jun into a useful weapon against Microsoft. Data interoperability meant that users would have no worries about the future, and the stone that Microsoft lifted eventually smashed itself in the foot.

Later, wps developed Linux and mac versions one after another. The scope of application is wider. Now that the counter-offensive horn is sounded, how to regain lost ground and grab back the lost share? free! The personal version of wps is free to use for life. Enterprise version, professional version charge a certain fee. In this battle, WPS, like Hongmeng, is betting on the future.

In 2005, piracy was still rampant, and free wps was no longer the sweet potato on piracy. In the future, piracy will definitely become less and less, laws and regulations will become more and more complete, and there will be less and less room for pirated software. I don’t need money for the original version, but I’ll give you a try and update. Come on, try everyone! The war between genuine and pirated editions won a protracted battle.

For WPS, now I am full of confidence in its quality. Just like today’s Hongmeng strode forward with confidence. China is now at the forefront of the world in terms of technology and software. It is definitely not because of good luck or technical support from developed countries. It is because a group of Chinese people with knight spirits silently contribute to the country and the people.

To this day, the United States has never stopped its technological blockade, as it was 20 years ago and after 20 years. From software to hardware to system. From Huawei, ZTE, to Jinshan Douyin. Only when the Chinese have mastered the real technology will we have the right to speak. Technology without borders is just a beautiful lie. All technology will become a weapon for hegemonism to maintain its status. And as the light of the nation, a high-tech enterprise can fill the gap with tenacity like countless revolutionary martyrs, fill the gap with blood, conquer highlands from the territory dominated by hegemony, and build the Great Wall free from the intrusion of foreign powers.

The analysis report from Bitdefender researchers said that Teabot malware can perform attacks through Android Accessibility Services, view private messages, steal banking information, steal authentication codes. of Google,… and even take full remote control of the victim’s devices. (Artwork: Unsplash) Distributing malware directly from app stores would be difficult, so hackers use the method of impersonating top-rated apps distributed on third-party websites. . According to research by Bitdefender, fake Android apps include antivirus, media player, health, etc. To deceive users, the fake app’s name and logo will be copied. copy almost or exactly like the real application.

Huawei’s HarmonyOS. Huawei launched HarmonyOS in 2019 after the US put the company on a “blacklist” and did not have access to Google’s Android operating system. This embargo, along with Washington’s ban on access to key semiconductors, has crippled Huawei’s smartphone business, just months after becoming the world’s number one smartphone maker. Developed since 2016, HarmonyOS can work on many of Huawei’s internet-connected devices, from smartphones to wearables. This operating system allows developers to easily build apps to work on a variety of devices. According to Huawei, version 2.0 of HarmonyOS has many interesting features such as Mirror Mode, Extended Mode and Collaboration Mode. Currently, the two most powerful operating systems in the world are still calling Android and iOS, other operating systems from Blackberry, Microsoft’s Windows Phone and Amazon Fire devices currently only account for a very small market share. To help its operating system grow, experts say Huawei’s biggest challenge is software applications, with the company having to convince software developers to reprogram its apps and other content. to operate on HarmonyOS operating system, through which consumers will continue to buy Huawei phones. As planned, right in the third quarter of this year, Huawei aims to be able to release HarmonyOS 2 for Nova 6/7/8, Mate 20 and all remaining MatePad tablets. The company is also expected to install this new operating system on V and S series smart displays, M6 tablets and Mate 20 X phones before 2021 ends. In the first half of 2022, Huawei will bring HarmonyOS 2 to Mate 9, Mate 10, P20, P10 and Nova 5 phones.

The report found that as many as 23 apps are available on Google Play, each with between 50,000 and 10 million downloads, violating privacy guidelines in the collection and storage of user information. Some applications are less secure, leaving users vulnerable to personal data leakage. (Photo: Check Point) Of these, there are 13 applications that store user data in the cloud but are not secure. This means hackers can easily access data from the outside. Hackers can even modify the developer’s notice, and replace it with malicious links or misleading content. Users’ personal information is easily leaked when using these applications. (Photo: Check Point) These vulnerabilities put at least 100 million Android users at risk of phishing, identity theft, and malware attacks. 13 out of 23 apps have extremely poor security, allowing hackers to access public data, but Check Point only lists 5 applications that need attention: This Screen Recoder app was found to be storing users’ passwords on an unsecured cloud service, leaving the data vulnerable to leaks.

A Huawei store at a mall in Shanghai, China. Photo: AFP/VNA In a short video posted on social networks, Huawei said that the HarmonyOS operating system will be officially put into use from June 2. At the same time, the company’s internal announcement said that Huawei CEO and founder Ren Zhengfei (Ren Zhengfei) announced major investment strategies in the software sector. HarmonyOS operating system was released by the Chinese telecommunications “giant” on August 9, 2019, in the context that this corporation faces the risk of losing access to Google’s Android operating system due to one of consequences of trade tensions between China and the US. According to the announcement, Harmony OS will be applied on a series of smart devices, including wearable technology devices. HarmonyOS also enables artificial intelligence (AI) compatibility and can also be used on personal computers and other devices. Huawei has been developing the operating system since 9 years ago, but information about this platform only appeared after the US put this company on a banned list in mid-May 2019, thereby blocking the access of the Chinese corporation. Nation for from chip to Android operating system. Every year millions of Huawei smartphones are installed. Therefore, the introduction of HarmonyOS plays an important role in the future of smartphone production activities of the Chinese technology group. Huawei’s rollout of its own operating system comes amid a slump in smartphone sales and overall revenue for China’s top technology group since last year when US sanctions took effect.

The Microsoft Office app for Android is now getting a dark mode soon. Photo: Google However, at the time of launch of the integrated Microsoft Office application, there was no dark mode for devices running the Android operating system. Many users have complained and asked Microsoft to add dark mode in Office applications. This feature will help them edit documents without the glare of the device’s blue light affecting their eyes. Recognizing user feedback and realizing the lack of updating dark mode for Android operating system, after more than 1 year of development this mode is now available to Android users in an update Upcoming. Android users with the latest version of Office apps will automatically adjust to dark mode if the device is already set to that option. In addition, users can also enable or disable dark mode by touching the profile icon on the home tab in the Office application. Then select the settings and choose light, dark or the system default to customize the theme. Microsoft product manager Sourab Nagpal said this is a feature that has been requested by many customers. This mode is well-received by many people because it provides comfort when reading documents and working on mobile devices. Microsoft says it will roll out dark mode for Office on Android in the coming weeks, so it may not be available to all users right away. Dark mode was updated by Micorosoft for iOS operating system last year along with the release of integrated Office. Devices like iPhone, iPad can read documents using Office applications comfortably just like Twitter, Facebook or WhatsApp experience with a dark color adaptive interface.

High-end Android devices are less likely to fall into this situation. However, with users of mid-range and low-cost products, there have been many complaints about Google’s operating system. Part of that is because Google’s operating system consumes a lot of hardware power when operating. (Photo: Amelia Holowaty Krales & Vjeran Pavic / The Verge) Known for running lots of apps in the background, Android often has higher hardware requirements than iOS for it to function properly. Over the past 10 years, smartphone hardware has seen a major change. For example, RAM has gone from 2-3GB to 8-12 and even 16-18GB on some high-end gaming phones like the ROG Phone. Chips on Android smartphones are already on par with Apple’s flagship chips. As a result, performance has been greatly improved. (Photo: James Martin / CNET) With the recently introduced Android 12, Google shows that improvements in hardware are not enough, the company has finally started to pay attention to other aspects of “smoothness” – software. Accordingly, Google has begun to pay more attention to the management and distribution of system performance on Android 12, to provide a smoother experience for users, especially on mid-range and low-end smartphones. (Photo: Amelia Holowaty Krales & Vjeran Pavic / The Verge) The newly released Android 12 is said to have the ability to more closely manage background processes such as Android System Server, Activity Window and Package Manager. These background processes often “work together” and this makes it impossible for low-cost, mid-range devices with limited hardware to run as smoothly as users want. (Photo: 9to5Google) This is not a “feature” that can be turned on/off by the user. Google promises they will improve background processes to make your phone run smoother, more responsive. Animations are now less jittery, and improve the gesture navigation system, which is far less efficient than it was on the iPhone. (Photo: Presse-citron) Coupled with increasingly powerful chipsets from Qualcomm, and displays with high refresh rates, Android devices will feel faster and faster.

This error has affected Apple’s iMessage messaging platform and social network What’sApp. Recently, a similar error has appeared on the social network Instagram, which can cause any iPhone model or even old Android smartphone models to be paralyzed when clicking a special Story. This Story may cause iPhone and Android models to freeze immediately after being clicked. (Photo: Mrwhosetheboss / YouTube) Accordingly, Story can cause iPhone and Android models to freeze immediately after clicking posted by an Instagram user called “pgtalal”. When the user clicks to view this Story, it will show up on a gray screen with random Arab words on it, immediately the smartphone will also freeze and cannot perform any task. (Photo: Mrwhosetheboss / YouTube) (Photo: Mrwhosetheboss / YouTube) At this point, the user can only restart the device for the device to work again. Arun Maini from Mrwhosetheboss went into the analysis of this particular Story of “pgtalal”, discovering that the user named “pgtalal” created the Story with two extremely large stickers inside, up to tens of millions of inches without What photo sharing platforms can support. That’s why older iPhone models as well as Android crashes. Oddly, though, the high-end Android models can still function properly after watching this Story. High-end Android models can still function normally after watching this Story. (Photo: Mrwhosetheboss / YouTube) Although Instagram does not allow users to post stories with giant stickers, but users “pgtalal” did some tricks with HTTP Proxy. This allows him to post giant stickers on Instagram’s servers. Because the sticker is very large, the iPhone and the majority of Android smartphones do not show this sticker, thereby causing the device to hang.

Translator｜ Ma Kewei Planning｜ Tian Xiaoxu This is a story with a complete aftermath. As a full-stack web developer with almost sixteen years of development experience, the author knows all the technologies required to build web applications. In recent years of work projects, the author became an Android developer for the first time. After a period of running-in, the author realized that the developer’s thinking also needs to be transformed from web development to Android and mobile application development. Most of the wrong paths for the newbies of Android development can be solved by refactoring or modifying the build process in the later stage of the project, and continue to polish until the unit test perfectly covers all the situations required and can also handle some small errors. But the rest of the missing fish are not so easy to solve. These are enough to have a lasting impact in the life of the app and make people want to overthrow the entire project. Some of the mistakes even make the author ashamed to say that he has made mistakes. Pass them. The following will provide some tips to prevent the time paradox (laughs) when you want to go back to the past and redo the project. I hope it can help you prevent the bad troubles that are hard to get rid of. Add in-app update immediately. It wasn’t until a year after it was released that we plugged the update notification function into our app. If the built-in update reminder function is added at the beginning of the project, then the process is fairly simple, but if it is delayed until later, it will inevitably cause a lot of problems, including: the need to build a custom process manually, and the user to try it on his own Skip the update. Believe me, this feature will be a breakthrough change for your app. Existing users of the app may have become accustomed to the in-app update function through other apps, and even take it for granted that this should be one of the features of the mobile platform. But in fact, it wasn’t until I personally experienced Android development that I knew that this feature had to be manually added by the developer. When your app unfortunately stops running, users will not look for software update packages, they will only uninstall and then install them, or even worse, they will leave comments in the app store. Restrict API key Let the program run first, and then apply a patch if something goes wrong. Maybe you also have this habit, but please don’t continue to delay. Point out an article about API keys on Google Cloud Platform, but for other platforms, the same applies. For GCP (Google Cloud Platform), we only need to log in to the Google account and select the API key to be restricted, and the system will jump to the key attribute interface. Select the Android application in “App Restrictions” and click “+” to add the package name to the API key that needs to be restricted. As for adding certificate fingerprints, you can directly copy the commands on the page and follow the instructions on the right side of the page. It only takes a few minutes to complete. We only started restricting API keys two years after the app was shipped. However, after the restriction, a map function of the app went on strike. After rolling back the changes, it took us a lot of work to find the problem. Most of the official Google software packages used by the app can be perfectly adapted to the code behind the restricted API key. Only one of the maps needs to rewrite the other set of API call codes. If we can consider the limitation of the API key at the beginning of the project and write it into the source code, this will undoubtedly increase the development time, but in the later stage, we can no longer worry about the limitation. The story does not end here. In order to ensure the normal operation of the map and limit the API key, we have to perform a mandatory update. We have background statistics to monitor the user’s update process, and the data shows that 90% of users update only a few weeks after receiving the update notification, while the other 10% still choose when the map is almost completely out of order. Without updating, I don’t know how they endure this kind of bug. Internal API version control When I was still focusing on web development, I never understood why someone would want to do this. After updating the front-end code, why keep the old version of the API? No matter how you think it is useless waste. However, when the software version used by the user is different, a major update of the API may cause a large-scale software crash. The method of in-app update can help alleviate this problem, but the process will be extremely long. Dividing API versions is more like a quick and simple solution for this kind of software crashes, rather than over-engineering as I once thought. Want to go offline beforehand Our app has practical goals. When we received feedback from users that the app reacted stuck and the response timed out, I was just a novice in mobile app development, and I just came across a new term: Offline First. If the user fails to connect to the Internet, all unuploaded and unsaved things will be lost, and when the connection is restored, they will have to re-enter all the content. The priority offline structure will write the changes to the local database, and then synchronize when there is a network connection. In this way, the user can use the app offline, and the response will be faster when connected to the Internet. The user no longer has to wait for the server to send back a response before proceeding to the next step. The offline priority function may be more difficult to implement in the later stage of the project. The difficulty depends on the complexity of the app’s data. So please decide as soon as possible whether the app needs it. We are still studying how to better implement this feature in our “old age” app… Choose navigation items carefully If your Android app has a complex structure and many interfaces, it will be more troublesome to modify the navigation items in the later stages of the development process. Our app was directly changed to the form of bottom navigation in the later period. In some situations, the Activity in Android development can be regarded as the code of a certain screen in the app; Fragments, which are only available in Android 3.0, can be understood as the subview code or part of the code in the app. The layout of both is defined through XML. Our navigation points to the main functions in different areas of the app, and these small navigation cards each lead to different sub-functions, connecting more than 30 activities in total. These are just four fragments in this Activity-based app. Navigation drawer is another common navigation form, the main service object is the navigation needs of Activity docking with Activity form. Bottom navigation Because the bottom bar of the app is always visible, its design object is fragment navigation. After adding the bottom bar to the Activity, then we only need to type its related code into the Activity and add its view to the layout of the Activity. In this way, by clicking the button on the bottom sidebar, we can load the fragment into the Activity. So, in order to add the bottom navigation bar in the app, I tried to convert Activity to fragment. The result was very tragic. Excessive bugs directly caused the software to crash and wasted a month of my time. If we only have five or six activities, it may not be too difficult to solve, but in fact our app has more than 30 activities! This directly led me to give up other work this month and focus on adding navigation functions to each Activity. I also tried to create a helper function, but this did not save me much trouble. In the end, I still have to write code for the Activity one by one. At the same time, I also need to add the bottom sidebar to all layouts and make room for this little guy in the existing layouts. In addition, the Activity stack must be programmed to prevent race conditions. Although the process was cumbersome, it was successful in the end, and the effect was not bad. It’s just that if I can add the bottom navigation bar at the beginning of the project and start the design based on the fragment, it will be much easier. This is just an incomplete list… Of course, there are many other things to consider when starting your first Android application, such as adding unit tests, not changing the mode of an app after determining it, and so on. But if you have been exposed to other types of development models before, these should be familiar to you. Maybe you will not encounter exactly the same problem as mentioned in the article, but I am afraid it will not be too different. Hope these little tips can help you realize that Android development is very different from other types of development, and the influence of these development decisions may last for a long time. https://triplebyte.com/blog/everything-id-do-differently-if-i-could-go-back-and-rewrite-my-android-app-today

I’m a pretty neat person. Furniture when going home like backpack, glasses, keys or wallet are stored in the correct tray in a box next to the door. Thanks to that, I rarely have to look for things that are important to me before going to work. However, no matter how neat I am, there are times when I lose my belongings. I dropped the wallet on an acquaintance’s car, and because the wallet fell into the slot under the seat, my friend couldn’t find it. Had it not been found by the car washer, I might have had to go over and over again. These are situations where a misplaced device like the AirTag comes in very handy. I was very excited when Apple introduced the AirTag, but it still has many inconveniences when it comes to real-world experience. Accessories “cheap” in the Apple way Excluding EarPods or chargers, AirTags is Apple’s cheapest standalone product. This accessory has a genuine price of about 800,000 VND, and if you buy a set of 4, the price is a bit lower. However, for many this will not be the final price to be able to use AirTag. The device has a round design and two sides are not flat, meaning it is difficult to secure in the compartment of a handbag. Leaving AirTag in your wallet just makes your wallet look good, while lowering your device’s notification volume. AirTag is also quite thick, so placing it inside thin wallets will make the wallet look up quite a lot. In addition, if the AirTag is placed in the wallet or compartment too thin, the efficiency will also decrease. The solution now is to buy a leather pouch. Although there are no prices in Vietnam, the genuine bags that Apple sells are priced equal to or several times higher than the AirTag itself (from 29-449 USD). Leather cases of craft units in Vietnam also cost about 200,000 VND or more. If you buy this accessory, the price of AirTag will be nearly 1 million dong. AirTag pairs very quickly with iPhone. Due to not being able to buy a holster in time, I used the “bare” AirTag, and immediately understood why a holster was needed. In less than a day of use, leaving this accessory in the backpack and wallet compartment, both the aluminum and plastic sides of AirTag have had scratches. Actually scratches will not affect the function of the device, but for those who require high looks, these are still the points to pay attention to. Well done the main function Connecting AirTag to iPhone is very simple. Just bring the accessory close, the machine will automatically recognize and the set-up takes only about 30 seconds. This is a big plus compared to other finder devices. To find items attached to AirTag, users have 3 ways. First, they can go to the Find My app, choose to show up on the map to see the last recorded location. If you are in the same apartment, you can press the speaker button to let the AirTag play the sound. The third method only applies to iPhone 11 onwards, allowing the display of the direction and distance to the nearby AirTag. The “exact find” function worked quite well, but still occasionally lost the signal. The Find My network with billions of devices running iOS is a huge advantage of AirTag. No need GPS or network connection, users can still find the AirTag when it is near any iOS device. Testing in city conditions, I found the position of AirTag on the map was quite accurate. The challenge will come when you want to find the AirTag nearby. The AirTag’s “speaker” is in fact the white plastic side of this device. When you select a sound feature, the plastic face vibrates to create sound. This sound is only enough to be heard in an apartment, when the background noise is quite small. If you search inside a multi-storey house, or assume your family member has the TV turned on quite loudly, you will be hard pressed to hear AirTag’s sound. This is why you should not leave AirTag inside your wallet too tight. At that time, the volume of AirTag emitted will be much smaller, reducing the efficiency when searching. The search when the AirTag is lost is quite effective, the address is accurate. The UWB wave precision search is also useful, but efficiency depends on the environment. When I tried to leave AirTag in the living room of a 2 bedroom apartment, the iPhone frequently reported “weak signal” when I went into one of the bedrooms. Only when the distance is less than 4 m, and there is no barrier between the iPhone and the AirTag, can the device be able to accurately indicate the distance and direction. Combining all 3 of these features, the ability to find lost items will increase significantly when attached to AirTag. However, there are still environments where AirTag is not very efficient, like in a large apartment, or in the middle of a crowded shopping mall. It is also not suitable if you want to leave it on your motorbike to look in the parking lot, as cheaper and louder accessories are available on the market. It would be disastrous if used the wrong way At launch, Apple stated that the AirTag was an accessory “to track things, not to track people”. The company also integrates a number of features so that users know when someone else’s AirTag comes with them. However, in practice these features all have vulnerabilities. The current AirTag can still be used to spy on others. The first way AirTag notices is sound. According to Apple, after “a while”, if an AirTag is separated from its host device, it will squeal to get attention. The company did not specify how long that period was. Just squeeze or stick the tape around the AirTag and the sound will be very soft. According to the Washington Post , it took three days since the last time away from the owner, the AirTag cried for about 15 seconds, and then rang every few hours. The 3-day period is quite a long time for AirTag owners to keep track of the places the victims visit. Besides, reducing the sound of an AirTag is not difficult. If you detect an AirTag that is not with the same account but has been nearby for a long time, the user’s iOS device will also pop up a message saying there is a strange AirTag. The victim can press play to find the strange AirTag, but cannot access the map or find the exact same as the official AirTag. However, in my hands-on experience carrying the strange AirTag all day, I never get a notification on my iPhone. Also, if the victim uses an Android phone, they won’t receive any notifications. AirTag uses the familiar CR2032 battery, sold in every watch shop. AirTag still has many vulnerabilities to be misused. That’s not to mention if the AirTag owner is spying on a relative and knows their iPhone’s password, that person can go into the Find My app and turn off notification when it detects a strange AirTag. Although Apple promises very well, AirTag can still be used as a tracking device for others. In the future, the company may update to reduce the alarm interval or adjust the notification feature. At present, AirTag still has many major vulnerabilities that can be exploited for the wrong purpose. Should I buy AirTag? If you are an iPhone user and forgetful, AirTag will be a very useful accessory, especially with important objects. The price of nearly 1 million is not high compared to the effort of redoing papers in your wallet, or hitting a car key. AirTag can be said to be a huge reason iPhone users continue to stick with Apple’s ecosystem. However, if you do not use an iPhone, there are many other options on the market, with prices as low as half the Samsung SmartTag or Baseus Intelligent T3.

(Photo: iMore) Accordingly, users can enable a feature called “Offload Unused Apps” to automatically uninstall apps they rarely use without losing any data. do related to them. That way, users can instantly free up memory, then reinstall apps as needed. (Photo: MobileSyrup) Rumors from a few months ago suggest that Google may be developing a similar feature for Android 12. Now, the latest report also shows that Android 12 can actually “freeze” unused apps automatically to free up space. (Photo: Internet) According to XDA-Developers, this feature hasn’t been included in any of the Android 12 Developer Preview releases yet. However, the “Unused Apps” freeze was discovered in a leaked build that this blog discovered. Specifically, XDA-Developers discovered that Android 11 Developer Preview 3 has brought the new “Auto revoke permissions” feature. As the name implies, the feature revokes permissions for apps that haven’t been used for a few months. (Photo: Android Authority) Next, the official release of Android 11 provided additional features related to the “AutoRecover” permission. The system will notify the user when the permissions of an app have been revoked, and the revoked apps will show up in the App Settings not being used. And it looks like Android 12 will bring a new “freeze” feature to apps not in use. If enabled, this feature will not only revoke permissions as before, but also completely uninstall apps to free up storage space. The interface of managing unused apps on Android 12.

Regarding whether AirTags can be used to track people, my thoughts have gone through the following changes: “Cannot track iPhone users but can track Android users” –> “None can be tracked” –> “All can be tracked”

False perception

Apple stated at the press conference that if there is an AirTag that does not belong to you and moves with you, your iPhone will receive a notification and warn you.

So I thought at first that AirTags can’t track iPhone users, but it can track Android users.

After the press conference, Apple’s official website released AirTags instructions: if an AirTags is not with the owner for a period of time, when it moves suddenly, it will automatically make a sound so that Android users can also hear it.

So I thought AirTags can neither track iPhone users nor Android users, but I seem to be wrong again.

Real details

Fast Company interviewed two Apple executives, Kaiann Drance, vice president of marketing, and Ron Huang, senior director. This report revealed the following information.

1) Only iPhone users running iOS 14.5 or above can receive warning notifications that unfamiliar AirTags is tracking you. Users who don’t like to upgrade the system are easily tracked.

2)What is worrying is when the warning notice is issued: According to the interview in the article, AirTags will not notify users until they return home or arrive at certain locations. iPhone will automatically infer where your home is, open “Contacts-My Business Card”, it will show the location of your home it inferred here, or open “Settings-Privacy-Location Services-System Services-Important Locations”, it will also be here Shows the location of your home estimated by the iPhone and other places you frequently visit.

3)Does this mean that if I secretly stuff an AirTags into a stranger’s backpack, then I can know where TA lives?

4) When you come home and find someone using AirTags to follow you, the first thing you need to do is to find this AirTags, right?But you may not be able to find it.If you are more vigilant, click immediately after seeing the notification, the phone will automatically open the “Find” application, and display a play button, click it will let AirTags sound to help you locate, after finding it, remove the battery to terminate the tracking.

If you are unlucky and happen to run into AirTags and automatically change the ID, then you can’t let it play a sound. For your iPhone, the AirTags after changing the ID are not the same AirTags, so it will think that no AirTags are tracking you. Only when this AirTags follow you to the next location, the iPhone may re-issue a warning notification.

5) Why does AirTags automatically change ID? Because if your AirTags ID does not change, the anonymity of this AirTags cannot be guaranteed. This ID needs to be shared to unfamiliar iPhones around you via Bluetooth to help you locate AirTags. If your AirTags never update the ID, then hackers can save all the AirTags ID sent actively, and you can do something based on this ID in the future Bad things, such as scanning a circle to determine if other people’s AirTags are nearby.

6) But, didn’t it say that AirTags will automatically beep? Yes, but according to the interview:Only when AirTags have left the owner for 3 days, will they make a sound!

7)Does this mean that I can use AirTags to track an Android user for 3 days?Apple said that it may extend or shorten this time through software upgrades in the future.

to sum up

Apple needs to strike a reasonable balance in the three aspects of “protecting the owner’s privacy, protecting the privacy of others, and effectively tracking items.”

If AirTags would easily send warning notifications to unfamiliar iPhones passing by, there might be a new profession dedicated to stealing AirTags? Although AirTags has a so-called pairing lock, even if someone else gets it, it can’t be re-paired for him, but people always have a way to use it.

If AirTags make a sound easily, such as making a sound when the owner leaves the owner for 10 hours, then the owner goes to work and the family moves an item with this AirTags, which may also trigger the alarm mechanism, which can easily cause interference to the user.

In fact, trackers have existed for a long time, and we can even see news in the newspaper that xx people found their other half cheating through the trackers, but the trackers are very far away from the lives of ordinary people until AirTags is released.

Apple’s influence is great, and AirTags will be widely used. Apple’s balance of AirTags may give people a chance. I think it is necessary to let more people know the details of the working mechanism of AirTags and be careful to be tracked by AirTags.

Finally, if you find an item lost by someone else, there is an AirTags hanging on the item, then you can scan this AirTags with any NFC-enabled mobile phone. If this AirTags is turned on by the owner in Lost Mode, you will be able to find the other party after scanning. I hope you can help the other party retrieve the item.

Samsung plans to adopt new technology for foldable smartphones. This could be a successor of the Galaxy Z Flip or the Galaxy Z Fold. Similarly, Xiaomi also placed the camera under the Mi Mix 4 screen. There were information and images leaked about this device not long ago. Camera under the screen is a new trend on smartphones. Photo: Phone Arena. Other Chinese phone makers including Oppo, ZTE and Vivo also plan to launch smartphones with cameras hidden under the screens in 2021. Specifically, Oppo applies new technology on the folding screen version, similar to Samsung’s idea. Meanwhile, ZTE will release the Axon 30 Pro 5G, an improved model from the first phone with an under-display camera. Vivo also plans to launch a phone with a similar design, but there’s no specifics yet. ZTE is a pioneer with this feature. In September 2020, the company announced the Axon 20 has a 32 MP camera hidden behind a semi-transparent AMOLED screen. The camera technology under the screen is still incomplete, the photo is blurred, the camera position is clearly exposed. Photo: Archyde. According to the Phone Arena The new technology looks impressive, but not complete yet. Selfies from the Axon 20 lack sharpness. Even the screen in the camera position is easy to recognize, especially when displaying bright colors. However, manufacturers who are about to join the new trend will continue to improve, bringing the camera under the screen more perfect. After the fingerprint sensor, the selfie camera is the next part placed inside the screen towards the completely bezel-less front design. In recent years, phone companies have tried to increase the display ratio on the front by creating a notch and punching design. However, the limitation of this solution is to create a split on the screen, causing distraction. The man tries to make his own foldable iPhone To be able to make a foldable iPhone, you have to find a screen that is flexible enough to integrate the digitizer and find a way to integrate the logic of the iPhone board with the screen.

The big screen and big lens are what attracts me the most about Mi 11 Ultra. A mobile phone always has some gimmicks, otherwise I don’t know what to say when I introduce it to others. And the huge rear lens design of Ultra is enough to become a hot topic for everyone to discuss.

The reason why it is so big is because Xiaomi has inserted the largest GN2 image sensor in the current mobile phone industry into the Ultra’s body. It is said that the bottom level is crushing people. At least in terms of area, Ultra’s image sensor is already unmatched. . The big bottom can capture more light, easily take brighter and clearer photos, and GN2 also has stronger focusing ability and night scene ability, of course 8K video is also supported. The three lenses are just right, at least in terms of composition, they are all lenses with strong practical value. Xiaomi also emphasized that these three lenses are all main camera-level lenses, thus ensuring stable image quality at different focal lengths.

The outsole, the large lens, and a small screen form the entire Ultra back lens module, which is recognizable in appearance. With a white ceramic body, it has both texture and beauty. Of course, different people have different opinions on appearance, and everyone has different aesthetics.

At the first glance of opening the camera, the picture in the preview box is basically the same as the picture seen by the human eye, but the color is slightly faint; the arrangement of various function buttons is clear, the upper part is the auxiliary function setting, and the lower part is the camera mode selection. Compared with the iPhone, the camera of Android phones will have many interesting functions built-in, such as beauty, movie mode, macro mode, tilt-shift shooting, etc. You can manually choose to turn off and on. Although it is a little complicated, it is also enhanced. Playability.

I pressed the shutter and took a few photos. The sudden delay caught me off guard. Obviously, the shutter has been pressed, but the camera hasn’t responded for a long time. This is an accident, but the frequency is not low, and it also makes the photo experience very fragmented. The same sense of fragmentation is also reflected in the multi-zoom switching. The rough switching without transition is really not elegant. Although it is innocuous, it can’t be called the performance of a flagship machine. This kind of software optimization problem does not only appear in the process of taking pictures, there will be some small bugs or inadequate optimization points in the whole process of using the machine, which will seriously affect the performance of Ultra’s flagship. Fortunately, these problems will be resolved later, and all that needs to be done now is to wait patiently.

In addition, there are several camera problems that bother me very much. Since these problems may be my own feelings, I will only list them.

1. The ultra-wide-angle distortion is serious, and the image quality loss is serious in the dark environment;

2. 5Difficult to focus, often pull the bellows;

3. The viewfinder is not displayed in full resolution. I am not sure about this. I personally feel that it is not as comfortable as an iPhone;

4. The color shift of the three lenses is large. I have said a lot of shortcomings, not because of deliberately embarrassing 11 Ultra, but because of giving enough expectations.

   There are also many good places, including:

5. The natural optimization effect brought by the outsole. You don’t need to turn on the portrait mode to take close-up shots, and you can get a good blur effect when you take a shot. This is a natural blur, not an effect that can be compared with computational photography.

   2, 2 and 5 the creative fun brought by zoom. I have expressed my love for multiple zooms many times, and many proofs are also taken with 2. The hard power of GN2 makes 2 still have good picture quality and tolerance even after the main camera is cropped. 5 and Periscope 10 are even more powerful tools for shooting distant scenes.

6. Later fun brought by software functions. Xiaomi’s photo album features are very rich, with a wealth of filters, as well as magical magic, you can also directly add stickers, text, frames, etc. to photos.

   Next are some samples taken with 11 Ultra for your reference.

   

   

   

   

   

   

   

   

   

   

   

   

   

   

   

   

   

   

   

   

   

   

   

   

   After taking the picture, let’s talk about other things

   I really like the appearance of the 11 Ultra, especially the rear lens module design. Although the bulge is strong, it is also recognizable because of this. This is the 11 Ultra, and there is no doubt that it will not be mistaken.Of course, more people hate this design. On the one hand, it is visually uncoordinated. On the other hand, there are some inconveniences due to such a strong bulge. For example, there will be nowhere to put the hands close to the lens module when playing games.

   

   As for the weight, it is very heavy, but it doesn’t make me feel top-heavy, and the bulge of the lens module is just enough to let the fingers rest on the phone. It feels safe when standing on the subway and playing with the phone. The look and feel of the ceramic back cover is completely different from that of glass. It is gentle and delicate, just like holding an ex-girlfriend’s hand.

   

   All the buttons are integrated on the right side of the fuselage, which is quite convenient to use, but the size of such a large fuselage is definitely more difficult for girls to hold. The upper and lower frame design is very simple, and the dual-speaker sound quality is good, much better than the iPhone 12 Pro used before. Infrared transmitter is a function that iPhone will never experience. It is very convenient to control the air conditioner and TV daily.

   

   The screen is amazing

   Don’t forget the slogan of Xiaomi Mi 11-a good screen. This one-billion-color four-curved screen is one of the top-level screens that deserves it, not to mention that it also supports 2K+120Hz simultaneous opening. The screen display itself is a very subjective thing. Everyone has different preferences and tendencies, but this Xiaomi screen is one of the few screens that made me amazed at first sight, even better than this year’s OPPO and OnePlus’s screens. All amazed me.

   

   The screen display of Android phones often has a variety of color styles. I prefer the primary color mode of the 11 Ultra, which is the most natural display mode that restores the original color of the content. At the same time, 2K and 120Hz must be turned on, which brings silky high-definition enjoyment. I must also praise that Ultra’s automatic brightness function really makes me very satisfied, almost as smart and reliable as the iPhone.

   Of course, there are some regrets. The 11 Ultra does not support the original color display function similar to the iPhone, and the 120Hz high brush does not achieve global coverage like the Samsung S21 series. The curved screen still cannot avoid accidental touch, and the edge return is sometimes not so sensitive.

   

   On the back of the screen, I have not explored any practical application points, because I did not put a film on the phone screen, so I would not choose to buckle the phone on the desktop, so I can’t see the content on this small window.

   Battery life and heat

   The originally highly anticipated Snapdragon 888 can only be reminiscent of heat and high power consumption. Although it is not called a fire dragon, under many heavy load scenarios, the continuous performance output of 888 is indeed less stable than that of 865. (The above is extracted from the major evaluations).

   

   In my actual use, the glory of the king with the highest special effects turned on in a round can feel the heat emitted by the body in about 20 minutes. The heat is concentrated under the lens module, and the perception is more obvious. In addition, if you are a serious game enthusiast, you must choose 11 Ultra carefully, because the thick lens module seriously affects the feel of the game.

   

   What’s more disturbing than fever is battery life. Regardless of the large 5000mAh battery of 11 Ultra, it feels no different from Android 4000mAh mobile phones in daily use. The most exaggerated thing happened on the first working day after I got the phone. 40% of the electricity was consumed on the subway, and I only stayed on the subway for less than 40 minutes.

   In addition to the 2K+120Hz high-speed brush, 5G is also a typical power-hungry consumer, so I generally turn off the 5G network, and the battery life will be improved significantly. The problem of large power consumption has been improved to a certain extent in the update of version 12.10. The actual use time can be extended by about 1 hour, which also reflects that the road to system optimization of 11 Ultra is still very long.

   MIUI

   Good hardware must have good software to play its full strength. Obviously, 11 Ultra and MIUI do not cooperate well.

   Frame dropping, power consumption, heat generation, and system bugs such as screen cuts and dislocations and application crashes are not rare. Of course, I believe that Xiaomi will solve these problems, and pay attention to the stability of the system while adding new functions.

   In addition, I still have to complain about the proliferation of MIUI advertisements. I have not used MIUI for many years. I can’t accept that there are so many advertisements on my mobile phone. It is refreshing and clean by turning off one by one according to the operation guide given by cool friends.

   The system localization and convenience functions are very rich. The more important thing is that the notification function of MIUI makes me feel that it is almost the same as the iPhone experience. I can receive the notifications I want to receive, which is very reliable~

   MIUI is a system with historical accumulation and unique thinking. After 11 Ultra updates the 12.5 system, another article will introduce it in detail~

   to sum up

   In my opinion, the 11 Ultra is not a regular digital flagship. It has a bold design and powerful hardware configuration. Even if it is a little exaggerated, it has enough qualifications. On the road to hit the high-end, Xiaomi tried many times but there was no strong response. Although the 11 Ultra has taken off violently, it is a bit insufficient from the current second-hand transaction price.

   I have been jumping horizontally between iPhone and Android phones many times. What impressed me is the rich functions and imaginative appearance and configuration of Android phones. However, in terms of system stability, Android phones have never been able to do the same as the iPhone. Reliable, just like the 11 Ultra camera, the shutter response delay problem still exists after several system updates. Therefore, on the basis of rapid update and iteration, Android phones should slow down appropriately so that the software and hardware can be better matched, so as to be able to exert the strongest strength.

   

   At present, it seems that I will continue to use 11 Ultra for a period of time. On the one hand, this multi-fold telephoto really brings me a lot of fun in taking pictures, and on the other hand, because the value of 11 Ultra has depreciated so quickly that it can’t be replaced. The Samsung S21 Ultra I originally intended. I hope that during this time, Xiaomi can strengthen the optimization of the system, especially the expected MIUI12.5, which is the match that Android Light should have.

IT Home understands that EKA2L1 is a cross-platform Symbian emulator, mainly written in C++, and has been developed for more than two years.It can currently emulate S60v1, S60v3 and S60v5 platforms, These platforms are carried in mobile phones such as Nokia 7650, Nokia N95, Nokia E50 and Nokia 5800 XpressMusic.The emulator is also compatible with games built for Nokia N-Gage phones, N-Gage is Nokia’s unsuccessful attempt on a mobile phone/game console hybrid in 2003. N-Gage only sold 3 million devices in its short life, so there are not many games developed for it, but N-Gage is still an important part of the history of mobile phones.

This emulator has been available for Android on GitHub for some time, but the app has just been released to the Google Play store. The app works best on 64-bit Android devices, but it also has experimental 32-bit support. When used with compatible software, EKA2L1 can run games at a higher frame rate than the original Symbian device.

Users need to find the firmware ROM of their device to use EKA2L1, and repack the Z drive of the device. There is a wiki article that describes how to dump ROM and file system from compatible Symbian devices. You can download EKA2L1 from the Play Store.
