For the past few days my 920 has been shutting down by itself and it won't turn on with the power button or the charger the only thing that works is doing power and volume down for 5 seconds. I've had to do this about 5 times in the last week or so and during the last 2 the weather and maps apps are giving me the wrong location. I really like Nokia and WP8 but this is becoming ridiculous. This is my 2nd replacement 920 and it's not even 3 weeks old, I had to send the last 2 due to overheating my question is should I get another 920 from AT&T or is this something Nokia will fix in an update?
