I was sitting outside using tune in radio. It is hot out. I had the phone in the shade. I could still hear the broadcast but the screen would not come on for either the fingerprint or button. I tried to hold the power key down but no change. I had it in a seidio case so i took it off and as always the phone was hot so i tossed it in the fridge to cool down. I took it out a little while later and the same thing, podcast but no screen or buttons.Now the broadcast ended so I dont know if the phone is dead or what Seems dead. I tried pulling the card and starting it but no luck. Tried calling no ring. Tried attaching to pc, nothing. Help!
