I left my phone locked for about an hour and a half (at at least 60% battery when I started). And now i go to turn it back on, nothing! at first, holding the camera button made the phone vibrate, but nothing on the screen. None of the buttons do anything. I plug it in the to charging dock and it vibrates, but nothing happens otherwise! So now im with a broken phone and *Undisclosed Person's* New iPod! Feel free to tell me what to do, as i probably already did it! This phone is less than 6 months old!
Nokia Lumia 920
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.
