I got my iPhone 5 yesterday, and am enjoying it.
However, it's turned itself off 3 times, twice when I was using Spotify. It's a very quick reset - black screen, Apple logo, and then back to the lock screen (closing any app you were in). All this happens over the course of 5- 8 seconds.
However, when you're on the tube, it's logged you out of Spotify and you can't log in again.
Anyone else encounter this? I got my phone from Orange, is there anything I can do?
Any guidance would be much appreciated.
