My Galaxy Note Edge was perfect the first couple of months. Then in October it corrupted my microSD card. It's gone down hill from there. My phone would freeze, overheat, randomly shut down and spend 5-10 minutes rebooting and shutting down until I took the battery out and start it myself, and the battery would drain from 60% to 1% in a matter of seconds. A few weeks ago, when it randomly shut down, I got a message saying "Downloading... Do Not Turn Off Target". I assumed I had gotten the upgrade to Marshmallow and left it over night. When I woke up the next morning, it was still on my screen. I googled and found that several other people had this issue and they recommended taking out the battery and SIM card for a few minutes then putting it back in. That worked and it started right up again. It's gotten worse and finally I gave up and decided a factory reset was in order. I've tried to reset it 3 times, but all of my stuff is still there. Yesterday, my phone died and this time, it won't even come on again.
