Hey guys. I've been having an overheating issue with the phone, but maybe it was me that did something wrong. I can feel the heat when charging, while using it during hot weather, and etc. I know something like this tend to heat up naturally. However, there is gotta be a point when it's not normal. Whenever I use apps like infogram for 15-20mins, it tends to get hot. I went to the apple store today and this GENIUS told me i need to reproduce the heating if i want to exchange it...but I can't. It randomly happens..or so I thought... Help... My question is: what can I do to replace it? or is it just me?
