I'm having the same issue as other users with my S7 and, after reading up on the issue, I contacted Samsung and then took the phone to Verizon store today.
Samsung told me to take it to the Geek Squad at Best Buy, as they were authorized to make repairs. Welp, that was wrong, and BB gave me the name and number of some individual who fixes Samsung phone. (Samsung advised that if my phone is less than a month old, the warranty is still in effect. It's not and a phone less than 30 days old should not be having these issues!).
On to Verizon where they told me that b/c the protective plastic over the photo lens was cracked, warranty was void and there is nothing they can do --- but wait, I'm eligible for an upgrade if I want to buy another $800 phone. The phone has always lived in a case, so I have no idea how the lens got damaged (though, I think there is a cut out in the case, around the lens, so I'll have to check that).
Point is, the phone is separating, it gets incredibly hot to the touch with minimal use and when not charging, and neither Verizon nor Samsung seem willing or able to do anything --- other than sell me another phone. BTW the phone has insurance, but with a deductible which, of course, I'm on the hook to pay.
Pretty unimpressed with both Verizon and Samsung.
your phone's 3+ years old & you don't say if you bought new or used & i'm guessing used.
contact: ubreakifix they do warranty work/repairs on both i-phones + androids.
We're disappointed to learn you're having trouble with your Samsung device, Awlbisson. Let's take a closer look into the device. Any physical damage to the phone would void your manufacturer warranty. Insurance is a great feature to have to replace your device if there is damage. Has there been any damage to the phone? When did the phone start coming apart? What's in use when the phone is getting hot? Are you using the charger that came with the phone?
