This app allows you to keep your screen on *only* when debugging is active on the device over Wifi (on Android 11) or USB.

It switches to the previously set display timeout when the device is unplugged or plugged into a wall socket.

Permissions

Notification Access: To monitor debugging notifications
WRITE_SETTINGS to change the display timeout setting to maximum allowed (30 minutes on most devices)
INTERNET for Crashlytics (crash reports)

This application is open-source under the Apache license and it is easy to verify that the build here is the same as the one created through GitHub Actions.

GitHub: https://github.com/AfzalivE/AwakeDebug/.

Note: Android GO phones are not supported because there's no way to get Notification Access on Android GO Edition.

DISCLAIMER: Please be careful on OLED screens as keeping the screen awake for long periods of time could cause burn-in.
