Android 16 QPR1 beta 2 starts testing the new animation for the power button long-press gesture we first spotted last month.

Android 16 Beta 1 has a secret. The three-button navigation option now works with Google's predictive back animation to let users see a preview of the action they are about to perform.

One notable new bit is general availability of Compose Animation Preview, which lets Jetpack Compose developers inspect and debug their animations.
