With Apple pushing iOS 15.3 RC to developers, this means that the official version is also about to be released. The RC version is actually similar to the official version, but the name is different. Compared with iOS 15.2, this time IOS 15.3 added a lot of new features, Apple also exposed the iOS 15.3 official version of the global region push time on the official website, come to see when your region supports upgrades!
Apple will release january 24, 2022 at 10:00 a.m. Pacific Standard Time, when it will push iOS 15.3 and iPad OS15.3 that support all iPhones and iPads. Due to the different time zones in the world, the local time in the region is also different, but the upgrade push is globally unified. The China region is in accordance with the Beijing time in the Eastern Eighth District, including Hong Kong, Taiwan, and Macau, china, all of which will receive pushes at 2:00 a.m. Beijing time on Tuesday, January 25. This time is also very much in line with Apple's past major upgrades, which means that after sleeping tonight (January 24), you can get up and upgrade tomorrow morning. You can also set up automatic update upgrades, which saves time.
This time Apple brought three major security problem fixes to iOS 15.3, the first is that the Safari bug caused browsing history to be tracked, before someone used bugs to steal personal Apple ID and Google ID browsing records, probably even your private browsing was also stolen.
The second major fix is the caption correction when iCloud private forwarding is turned off. After the original private function is turned off, the original text will show that the iCloud private forwarding function is not supported, and after upgrading iOS 15.3, if the private forwarding is turned off, it will let the user understand the reason for the closure.
The third is to patch the HomeKit API vulnerability, which can be modified according to the device name according to the vulnerability before, which causes the iPhone control center to be unable to control the original device with the "home" function. iOS 15.3 is primarily aimed at fixing security vulnerabilities that do not allow third-party apps to attack by bypassing privacy preferences.
Apple also mentioned in the support file that it covers privacy preferences, hoping that everyone can actively upgrade iOS15. In the new iPhones released in the past 4 years, more than 72% of users upgraded iOS15, but in fact, the upgrade coverage of iOS15 is much lower than that of iOS14. It should be known that iOS14 has reached 80% of the upgrade coverage rate 3 months after its release. This time iOS 15.3 is fixed for privacy security, so it will call users to upgrade quickly.
