Hi everyone. I just got this phone as a present for Xmas. A week ago, it did an Android update and restarted. That's it! It won't go past the splash screen! It won't come completely up and it won't let me turn it off! If I hit the power button to turn it off, it just restarts and freezes. I have to let it die to shut it off. I can't even get to the home screen to get to settings to do a factory reset. Can anyone help me with this?
