[Galaxy S9] display brightness randomly changes


I’ve been having trouble with the automatic display brightness on my device. It sometimes just shifts up and down, seemingly at random.

Someone in another thread for another Samsung phone claims that this is related to the sensor picking up light from the display, something I haven’t verified myself yet. A52q auto brightness issue with light theme in dark ambient condition

Has anyone else seen this or other strange behaviour with the auto brightness?

I would also like to get involved with development. I have a bunch of embedded Linux experience but so far no android. Who can I talk to for the S9? Where do I start? How do I run the latest unstable version? :slight_smile:
