ive tried rebooting, didnt work. but heres the problems, when i try hitting the home and search buttons near the edge of the phone, it vibrates and lights up, but it doesnt do anything. Also when i go to setting/security , i check the box that says require pattern. But when i sleep my phone and wake it up, there is no password to enter. Also i didnt press anything, but the phone kind of turned off (it went to the screen when there is a red ball and the orange lines light up going outwards) It happens when you turn on your phone too.
