My 4S gets SUPER HOT when I take it out of my pocket!! Then if I put it aside for several minutes, it cools down quickly. Do you guys also have similar problem? I'm wondering if it is a defect of my own device or a common hardware/software problem. (FYI, I've turned off the WIFI, still doesn't help..) Thanks! UPDATES: ------------------ Thanks for all your replies! 1, I do wear jeans, but just quite usual ones 2, It doesn't always happen, 2 or 3 times yesterday, and once today Both in my office. Anything to do with the bad signal?
