Last night I was playing Eternity Warriors 2. After a while (about 30 mins) I got bored and decided to play Ashpalt 7. Suddenly the game just closed without showing any errors like force close or something else. At that moment I noticed my hand was a little warm, so I removed the case and found out that the back of my N4 was very hot. I must mention also that while playing this heavy games the phone was plugged to original wall charged. Should I stop playing while charging? Should I stop playing to much time? Did the game closed because of the high temperature on the processor?
