For those who were having overheating issues I think I stumbled upon a fix. For those unaware and were lucky enough not to be plagued by this ailment,  the phone would reach external temperatures of between 40-50°C as viewed on your phone when you press the digits *#0228#.

I’ll go straight to the point… Two apps had been over reaching and over using the processor. These two apps are Samsung Link and Samsung Push Service. The trick is to disable them if uninstalling their update doesn’t work. This can be done by going to SETTINGS > MORE (TAB) > APPLICATION MANAGER > ALL (TAB). Once you’re there select the respective apps and uninstall the updates or go further and disable them. This is preferably done under the XXUAMDK UPDATE. This should free you to enjoy the wonderful Galaxy S4.
