So.... according to the title, you should already know what im going to talk about. Anyways, my tab is going insane!!! I cant stand it anymore... it has been running smoothly for the past few years but for the past few days, things have been going bonkerzzz! 1st problem- My auto rotate is on, but it will only rotate into a few directions.... It will only turn horizontally where the power button is, and vertically where the tool bar is against the 'SAMSUNG' sign.... 2nd problem- My tab notification shows that a USB is connected to my tab. but infact there's none!!! Please give solutions quickly.... Thanks
