I had it only once since i got the phone and was yesterday, like 15 minutes into playing Riptide 2
the phone was just warm, not even hot like it gets after hours of playing. i did a hot stress test of playing real racing 3 for 6 hours straight, thanks to my bro that helped in the play time.
now i wonder if i "melted" the waterproofing thing on the back plate with that ..
