So I just got the galaxy s4 (white 16gb) on wednesday. For a couple days I used the phone and noticed that after a couple minutes (not gaming) that the back of the phone (near the camera) heats up rather quickly. I know some people have this problem and technical support mentioned I can return the phone for a new phone within 14 days of purchase. I checked the battery status and it shows after 4 hours on battery its 54 % (starting from 100% of course). Is this a problem? I thought the battery would last alot longer. I heard there was an update for people in asia and india who said there were stability fixes and battery fixes. So should I return my device for a new one or wait til verizon gets an update?
