Google releases Android 16 QPR1 Beta 2.1 with a fix for your broken back button
Launcher and lock screen bugs are also squashed

Beta testing for Android's biggest redesign in years is humming right along, with Google already having released Android 16 QPR1 betas 1, 1.1, and 2 in June alone. The new version isn't expected to hit the stable channel until September, but Google is already back with yet another update to the firmware that will eventually become the next Pixel Feature Drop.
