Is anyone's phone turning off on its own? I've been facing the problem since last Friday. I noticed the location service is turned on by itself and minutes after turning it off, the phone shut down due to high temperature, but the phone didn't feel warm at all. Used Sony PC Companion to repair the phone and the phone had been working fine for the whole day, until I turned on the wifi. The location service turned on by itself again and the problem returned. Anyone has any idea in this?
