Yesterday when I was texting the brightness suddenly dropped to +-50%. And no my brightness is not set automatically. When I change the brightness, from 0% to 100%, after 50% the screen brightness doesn’t change. And this happend all of the sudden. Same after restarting. Does anyone know how to solve this problem?
