Re: Random Windows Phone 8 break (?)
Have you tried soft resetting the phone? Hold the power and volume down key for about 10 seconds, the phone will vibrate. Lots of people have been having similar issues with the Lumia 920. In the event that it doesn't come back to life, you can send it to Nokia for repairs/replacement. Nokia Care has by far some of the best customer service ever so it shouldn't be too much of a hassle.
