Same thing happened to me, lady said the same thing re: warranty. Doesn't matter. They fixed it free, no fuss. This bloating and expanding battery is a known issue and they are fixing them without question. It's mad dangerous. They don't want a repeat of the Note situation a couple years back. Thankfully I had my old S5 I could activate while it's been in Texas getting repaired. They even gave me a shipping label. So I paid nothing and now I'm goning to have an almost new phone that's approaching 2 years old. I'm pumped.
Also, call Samsung. your cell provider can't do a thing except activate an old phone for you to use before you ship it back to Samsung. Again, it took like a week and a half to send it in, get it repaired, and have it shipped back to me. Very pleased with Samsung's customer service.
My S7 Edge has the same exact issue. After 30 mins on the phone with them. She not willing to fix it for free or give a discount. I'm going on a long-haul trip (15 hrs). I"m not sure is it safe to bring the phone on the plane with me.
The same happened to me, it started one day when I noticed that there was a lighter part of the glass on my phone. A few days after that I noticed the whole side of my phone had the glass lifted off of the metal. I soon realized the whole plate was lifted off the phone. I don't know what to do, as my warranty is expired
I certainly understand the frustration and concern you must be feeling right now. I would be more than happy to further assist you with this. I'll be sending you a PM to ask for more information.
I've had my S7edge since May of 2016 so it is definitely out of warranty. I noticed that my phone is having this exact issue just last night. I have AT&T and I'm sure they will be of no help. Has anyone had any luck with getting Samsung to make it right out of the warranty period?
Samsung were prepared to "repair" mine if I sent it in, but Verizon said that Samsung had a program in place to handle this issue and dealt with it on the spot. You should at least try AT&T I think.
