So this is the 3rd time its happened to me, go to look at my phone and it is off. When i try to turn it back on, i can't. I have to remove and replace the battery to be able to turn it on again. The first time, the phone turned off on me while i was holding it in my hands. And it actually turns off, it doesn't just reboot. Happened before yesterdays update, and again today, so it cant be related. Anyone? Should i try to get a new one?
