updated software and phone frozen

Try to reset the phone by holding the sleep and home button for about 10sec, until the Apple logo comes back again. You will not lose any data by resetting, but it can cure some glitches.

Same thing happened to me, except I have the 6. I just got the phone, not more than two weeks ago. I decided to update to iOS 8.2 just to have the most recent software, and I was fine for a few days. Like I said, I just got the phone so I'm fooling with it, looking through my facetime application. I then get this notification that says something about a failure, and facetime closes, and it goes directly to the white screen with the black apple logo. Now, everytime I unlock my phone, it goes directly to that screen. I can't even use my brand new phone!!!!!!!!!!!!!!!!!!!!! I tried resetting it and all of the above. I visited my sprint repair center and the lady tried to hard reset it through iTunes and it wouldn't even go into reset mode with iTunes, so I have to order a whole new phone smh
