Galaxy S3 heating up really fast

[alphonsus2010]

My Samsung GT-I9305 heats up really fast, especially when running and using Internet connection (LTE or wifi). Within about 2-3 minutes of using internet connection for playing games, watching youtube videos or watching movies online, the bottom part of the phone becomes really hot. It's the entire antenna area. My friends who are using the same phone on the same software do not seem to have this problem, or at least their phones don't heat up so quickly...
Any guesses what could have caused this?

Have you tried restarting it?

Yes, many times

Well, it's not normal for it to heat up all the time. You may want to try a Factory Reset (after making a backup of anything important) and see if the same thing happens before you load up all of your apps. If it still heats up then you have a hardware problem.
