This app adds a tile to the quick settings panel that turns Always on Display on or off.
The app needs to write to the system settings and the following command has to be run from your computer via adb in order for the app to work properly:

adb shell pm grant org.alberto97.aodtoggle android.permission.WRITE_SECURE_SETTINGS

Please note that this app has only been tested on Google Pixel.
Different manufacturers may have implemented AoD their own way and therefore the app might not work.

NoteIt is possible to grant the permission without a PC by using LADB or App Manager
