I have a strange issue with my tab S6 since the android 10 update. What happens is when I unlock my tablet using the official case(just opening it) the screen comes on but it is extremely dim. You can only see it is on when you are outside. When it is in this state it doesn't let you use the screen to use the fingerprint reader to unlock the screen. If you press the lock button the screen flashed on then locks again. Any help would be appreciated.
