Anyone else experience this? All of a sudden, pushing a button will not pull up the lock screen. The buttons glow blue, but the screen is blank. Even if a call is received, screen stays blank. Is there some combination of buttons that will reboot? I'm not sure it's a good idea to remove the battery every day or two, after a year that seems like it could mess up the contacts or something. From what I can tell, the phone is still working, but the screen has somehow turned itself off. The phone has been rooted, but it's got the original ROM.
