I’ve recently upgraded IOS to 16.0.2 version on my Iphone 13 pro max device. After some times I faced with brightness issue. Sometimes brightness is at low level. I tried to increase brightness but it seems I can’t rise the brightness more than 50%. In menu bar I can rise upto 100% programmatically but physically it doesn’t rise more 50%. I mean it occurs when you hide brightness sensor frequently. In order to catch the issue, need to played some games and you hide/sgow brightness sensor frequently. Brightness is working but after sometimes it comes back to normal state. But whatever it is critical issue I think
