Everything works (Camera, Bluetooth, Wi-Fi) because it's based on Samsung’s drivers.

For most users, the most stable "verified" experience isn't a jump to Android 13, but a heavily optimized version of the stock firmware.

You cannot flash a custom ROM with the stock Samsung recovery. You must flash a T280-compatible TWRP build first.

On your tablet, go to . Tap Build Number 7 times to enable Developer Options.
