Yeah I'm having the same issue, it's getting to be a major one. Has happened three times, only fix is factory reset. Are you still getting notifications, sounds, and lights though? Cuz for me, when this happens, it seems that the heart is still beating, but I just can't turn the phone on. I would go to Verizon to ask for a new one, but I'm worried that they will give me a refurb or something. Or would they give me a new one?
