Last week I was reading on it and I went to slide to unlock my device. It lets me slide to unlock, then shows the screen for a brief second before turning dark again into stand by mode. At that time I just turned it off and went to sleep cuz I was tired. But today I turned it on again, and it DID IT AGAIN!!!! So I rebooted countless times! I even held the power button for 20 seconds and rebooted!
Why is it doing this all of a sudden???!!!!!!
