Summary Android 16 Beta 1 has a predictive back animation for three-button navigation. Pressing and holding the back button will show a preview of the previous app or screen.

The change hasn’t made it to the desktop version of YouTube just yet. Starting now, tapping the like button beneath the video will showcase a joyful animation as shown below (via 9to5Google).

Google is quietly refining the Android experience with visual polish and enhanced AI integration ahead of Android 16’s public release.
