I haven't had any screen issues in the past, but today my tablet randomly decided to go totally black on me. I looked online and some posts mentioned to check if the screen was actually off, or just stuck at 0% brightness. So I got a flashlight and it turned out that I could see the screen in the light of the flashlight, very faintly. I tried to manually change the brightness setting, but that didn't do anything. I tried to go into 'power saver settings', but the 'screen brightness' power saver setting is stuck on and won't uncheck. Restarting doesn't fix it. Plugging it in to the computer or an outlet doesn't fix it.
I haven't downloaded any applications that override the screen brightness.
I'm using the Galaxy Note 10.1 (not the 2014 version).
