I'm tech guy and as such I leapt on MM when it dropped because I'd read about some of the new features and wanted to start playing with them. My Sprint Note 4 had been an awesome phone for 2 years. Didn't buy an extended warranty because I'm an adult... I don't have kids... and I use a good case... in other words, I had no intentions of breaking it. Naturally, I assumed that Samsung would take the role that most manufacturers take and fix their device if they break it --- well they broke mine bigger than sh!t and now they are all but refusing to fix it because I'm out of warranty.
I had the local Samsung rep at best buy reflash it - twice, I had the Sprint rep at the sprint store reflash it - once, and I've deleted the cache partition on numerous occasions --- it still reboots every 20 minutes. Sometimes I can squeeze an hour or two of usage out of it, but inevitably it will reboot again right when I need it (usually for something work related). When I need it though, it not only reboots but then it wants to lock up on boot repeatedly and force me to disassemble the case and pull the battery, usually more than once. This typically is a 30 minute fight. And my battery life has completely gone down the tubes - 3 months ago I got 24 hrs of basic usage out of my battery, at the time of send off I was getting about 7 hrs of use if I was lucky.
So I wasted 2 hours of my life speaking with Samsung support (chat and voice) - chat told me to call voice, voice told me to send it in and fight with the repair manager about it but voice support would not provide any guarantees that Samsung would own the repair and both chat and voice deny the problem even exists. They both repeatedly said they had received no reports of the problem. Sent it in to the depot (currently back on my Note 2) and I received an email today, these [removed by Moderator] wanna charge me 70$ to reflash it again! I'm convinced that they don't care about me as a customer since they can't even be bothered to read the ticket notes that outline that it's been reflashed three times in the past week!
I just wanted to limp along until the Note 6/7 dropped and given Samsung even more of my money.... but now I question that decision.... do I just go ASUS at this point? At least they don't make their customers pay for the things the company breaks....
(P.S. To those saying just because this issue hasn't hit you (nahoku), it isn't 'widespread' --- you're absolutely incorrect. There are reports all over the web of users just like myself. In every case I've read about where the user was under warranty, a complete phone swap was done with very little hassle. I've read of one other case where Samsung owned the repair and took care of it, but for the most part it would seem that Samsung is telling everyone to 'Go Blow' if you don't have a warranty --- which is complete and utter crap.)
Point of the story... if you're experiencing this issue, warranty or not, fixed by yourself or not, please report it to Samsung. Right now they are still flat out denying that it's even an issue - when it very clearly is.
