About this project

Starting with Android 13, it's possible to control multiple brightness levels of the flashlight. To be able to use this new feature I've developed this app.

[!IMPORTANT]

The full functionality of this app is ONLY AVAILABLE for devices which support the dim functionality of the flashlight (hardware limited).
