In addition to the obvious innovations, the beta version of Android 12 contains hidden features that developers are currently testing. For example, the profile resource XDA-Developers drew attention to the appearance of animation on application icons during installation or updates. It should be noted that this feature is typical for the iOS operating system.
Twitter user @outbraegeous discovered this feature on a Pixel 5 smartphone running Android 12 Beta 1 and Google Play Store 25.3.17-21. It is difficult to say what it is related to, though, as XDA-Developers have not been able to get it to work on their devices.
Quite possibly, this is a feature of Google Play, and maybe the Pixel Launcher. In any case, Google is once again adopting certain decisions from Apple.
