So Ive had my tab for a few weeks, no major falls or anything and all of the sudden when I press the side button to turn it on the keys light up but the screen doesnt, its very clearly still on but the screen wont work. i have to power cycle it to get it to work. Anyone had this? Any ideas or fixes for it? Its not rooted (yet) so its still running all stock roms etc and no bloatware has been removed.
