[Q] Samsung S4 GT-i9500 overheat issue. topic

So I've been using the GT-I9500 for nearly two years now and I've noticed that it's been overheating a lot recently. I've flashed MIUI v6 on the phone and I'm still facing the same issue, particularly in the area around the LED flash on the back of the device and the whole sAMOLED screen becomes too hot to touch. Even now, I've had to put my phone down a couple of times before completing this post. Please help!
