Hi everybody, the light sensor of my Zenfone 8 is not working. I noticed it because when I have adaptive brigthness ON, as soon as I lock and unlock the device, the screen gets very dim (the slider is still up, and as soon as I move it, the brightness kicks up again). Later I tried some apps that let you read your sensors measurements. I saw that every app can read every sensor, but the light sensor, which does not give any value at all (some app shows 0 or -1, because I guess that's how the variable is initialized in the app). Is it a hardware problem? Is it common for just the light sensor to break? Can it be a kernel/driver/firmware/software problem? I noticed this issue after a few weeks I updated to Android 12 in July (waited long because I was not sure about the big android 12 UI...) and subsequently did all the following updates. Is there any way to detect if the problem is software with something lower level than app, like adb, and maybe solve it without sending the phone to warranty? Thank you!
Had the same issue here, it is gone now but I am not sure what fixed it though. It was super annoying. Brightness would drop to where I can't see at all then I manually set it to bright. Next time it would be the same issue. I have not reset my phone when I upgraded to Android 12 (and I don't plan to). Android 13 is coming soonish so I will hold out for that as I hate having to set up all of my banking and other security apps again (given that I need to get physical letters with codes to activate them)
