Same thing. Just using a radio app on 4G overheats the phone. I can only talk for a couple of minutes with 4G on. If I turn it off, it won't overheat as quickly. Reboots to kill apps does nothing. I do have a warranty on my Credit card so even though t-mobile wont allow a return, the Credit Card will fully refund me, but it isn't my first option.
Samsung, you are an awesome company and I have purchased many things from you, but you should fully test your products before release.
I also beleive you should do something to compensate those of us who have this issue, like a significant price cut on the next version, assuming it works.
