https://9to5google.com/2022/03/01/android-13-flashlight-brightness-control/ seems implementation precise. I can build and run an app to check how many brightness steps is available on Fairphone 4 (if more than 2 states).

Could also investigate F-Droid apps.

On Fairphone 4 LineageOS:

flashdim/blob/e77d4883b9475380e2d4082c2be4577a6183a9ae/README.md?plain=1#L228 describes Fairphone 4 as not supported for https://f-droid.org/packages/com.cyb3rko.flashdim/.

I do not understand https://github.com/polodarb/Flashlight-Tiramisu/issues/10#issuecomment-1776306151

DuckDuckGo and Google first page results for Flashlight brightness Fairphone 4 does not bring more interesting results. I guess the feature should be added at the firmware level, is Fairphone 4 firmware open-source?

The following 2 repositories seem to be the only ones concerning Fairphone 4:

WeAreFairphone/android_device_fairphone_FP4)

WeAreFairphone/android_kernel_fairphone_sm7225

Is there a native (i.e. without additional app) LineageOS flashlight variable brightness controller for compatible phones?
