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.

If you think it's worth to support this project, feel free to give a small donation ❤️.

The full functionality of this app is ONLY AVAILABLE for devices which support the dim functionality of the flashlight (hardware limited).
Here's a list of devices I know of which do support flashlight dimming.

• Google Pixel 6/7/8/9 series
• nearly every Samsung phone with Android 13
• many other devices from different manufacturers

The following list contains phones, which were manually excluded in the Google Play Store because of missing flashlight dimming functionality.
If the list contains any phone which does has a dimmable flashlight, please let me know.

Of course, I'm happy about any kind of contribution.
