I thought I was the only one experiencing this. I have a US issued TMobile Note 5 out the box. I did not drop it and there isn't any water damage. I've concluded it's a system glitch. We can't all be having the same problems with different carriers. I have seen a lot about Samsung pay which can make sense. It was already preloaded on the phone but when I activated it, I noticed the back button won't work. It is as if the left hand side of the screen acts up on certain points at certain times. Usually after a reset or power down/up, it is corrected. I didn't buy this phone to reboot it every so often to access certain parts of the screen. FIX THIS SAMSUNG
