iOS15.2 Beta4 beta version

[[438518]]

Apple finally pushed the iOS15.2 Beta4 developer beta version to developer preview users early this morning. Why do I say finally? Because I have really waited too long.

This update is 15 days apart from the last one, and users who updated last time must have been looking forward to the release of Beta4 like me.

If you upgrade from the previous Beta3 version, the update package is about 700MB, and the version number becomes 19C5050b after the update. It is a routine update.

Now let me tell you why I have been looking forward to this version update.

Because the previous iOS15.2 Beta3 version had an automatic brightness failure BUG, ​​all iPhone13 devices cannot use automatic brightness normally after upgrading. It is really uncomfortable without automatic brightness.

This system update finally fixed this problem. After testing, my iPhone 13 PM can now use automatic brightness normally.

In addition, the newly added cellular network "limit IP address tracking" function has been translated into Chinese.

By turning on this feature, users can prohibit some websites or operators from tracking your location and pushing targeted advertisements to you even on a cellular network.

Overall, this iOS15.2 Beta4 version is mainly a small update and there is no major functional update. However, for users who encountered automatic brightness failure in the previous version, this version must be updated.

In addition, after Apple recently closed the update verification for the official version of iOS15.1, some users found that devices from iPhone 6S to iPhone 11 can still be flashed with the official version of iOS15.1.
