PowerButtonSettings

Note that this app requires the WRITE_SECURE_SETTINGS permission that can be granted with EITHER a PC using ADB or root. Root is NOT required for this app, it is optional. Android 8.0+ is supported, with more features enabled on Android 10+.

Uninstalling the app will not reset the assistant configuration. You must click the Reset button to undo all changes made.

This project is FOSS in the sense that the source code is freely available at https://www.github.com/tytydraco/PowerButtonSettings. It can be compiled using Android Studio Canary at your convenience. While I offer support for the app, I cannot help you compile the app from source.
