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.

AirDrop is very useful for Apple ecosystem users but is being warned of being insecure. Experts said, AirDrop allows users to share files with Apple devices in contacts. During the process of verifying the connection between devices, AirDrop uses a “mutual authentication mechanism” to compare the user’s phone number and email with the entries in the other device’s phonebook. Basically, data exchanged via AirDrop is encrypted by Apple, but this security mechanism is assessed by experts as relatively weak. In fact, Apple just scrambles the phone numbers and email addresses exchanged in the process of transmitting through AirDrop. This security mechanism can be easily circumvented using simple techniques like brute-force attacks. Also according to security experts at Technical University of Darmstadt (Germany), the above vulnerability was discovered in May 2019 and has been notified to Apple, but Apple still has no specific patch. to fix the problem. Airdrop is a feature that comes pre-installed on iPhone, iPad or Mac (depending on the version of the operating system). Helps iOS, Mac devices connect together and can easily share files wirelessly with each other very quickly without affecting the quality of the file. Airdrop has been integrated on iPhone, iPod, iPad devices using iOS 7 or higher. Macbook from 2012 with OS X Yosemite (10.0) higher (except Mac Pro mid-2012). In addition, AirDrop cannot be used with other operating systems (Android phones, Windows Phone phones …).
