CameraLightSensor battery drain issue or not? [Android 11, Galaxy M21]

[Helge Nicholson]

Greetings.

I noticed recently my 'Screen on time' is less than 'CameraLightSensor' background time.

How's that possible? Is it still on while the screen is off? I don't use 'Face recognition' or 'Always On Display'.

What keeps it working? I don't want to switch 'Adaptive brightness' off, cause it's useful when the screen is on, but I want to stop the battery drain (or can we call it a drain at the current level?)

Please help me out.

That is very weird I know for a fact there is no light sensor in the cheaper phones as they all do it, weird how my s20 doesn't have a thing that says camera light sensor I think sometimes samsung themselves don't realise 🤣
