When I use the phone the screen brightness changes very often (sometimes every 5-10 seconds or so) even if the ambient light is the same (I’m at home and I’m not moving around) and the phone light sensor is always pointing to my face. It’s quite annoying… It seems as if there is some crazy battery…

@amoun Ahhhh okay, it seems like there is a proprietary AI from google, that is learning to adjust the brightness in a way that fits the user. I never used Gapps on my phones, I guess that’s why there is a difference in behavior between our phones. I didn’t expect google to remove adaptive brightnes…
