Why the hell my S4 gets so hot?

[Cappuccino]

It gets very hot when I'm on the phone for about 20 minutes (twitter, youtube, just random surfing) and the back starts to overheat, I can boil a freaking egg!

What should I do? Is there something wrong with my battery or something? I do not want to spend a new battery because I've had this phone for less than a month. WTF is wrong with it. I am sick and tired of it, I should of waited for the new iphone..

Any help?

Can you take it back? My S4 doesn't get hot.

I have no warranty and I've bought it online too.

You might try and borrow another battery.

I have this as a spare, it doesn't last as long as the OEM battery though.

If it's not a gray market phone, Samsung gives a 1 year warranty on their phones, contact them via their web site.
