Hi guys. I just got my contract with ATT for my S4 active few weeks ago. I did two factory reset. One soft, Factory Data Reset from "Backup and Reset", and another hard reset, from the recovery menu. I've been playing Samurai vs Zombie a lots for past few days, which make me realize how dam hot my screen is. So after searching online I found the code *#0*# provide you with the device temperature, and I record the following CPU temperature on my device. !! Recorded from outdoor on a sunny 70'F day !! Idle with no background apps : Around 43-46 'C Few apps and playing SvZ : Around 55-58 'C Is this temperature range normal ? I'm about to return to the store and get a replacement if not.
