I just picked up my Droid and it would not turn on. It was sleeping, so a simple quick press of the power button should have done the trick, but it did nothing. I assumed it shut down for whatever reason, so I held the button a bit longer. Still nothing. Panicking at this point, I popped the battery out and popped it back in. Finally it started up, thank god. Still, this was pretty upsetting and I have no idea why it happened. Any thoughts?
