To get set up with beta releases of Android 16 QPR1, you’ll visit google.com/android/beta and “Opt in” on your selected device. Any compatible Pixel (listed above) with your same Google account will be able to join the program on this page. Once opted in, you’ll be able to check for updates on your device to actually install the update. This usually happens within an hour, but can occasionally take longer.
Notably, with Android 16 QPR1 Beta 2, we’re seeing the update live now via the Android Beta Program, but as of 3:45pm PT, it’s still not live via OTA files for sideloading.
