So my Note 4 died ... I think the heat wave we're having right now is the cause!! It started rebooting randomly and eventually got to the point where it would boot loop.

Not a big problem, I have 3 Note 4 ... Grab the second one, wipe it, transfer everything over, only for it to break 2 days later!!! ( It's technically still functional, but unusable : it freezes for a second every 15 to 20 seconds).

So last one, wiped and installed everything (again) ... Only to realize that the keyboard is burned in the screen ... *Sigh"

But then I didn't pay for them, so meh!! ¯\_(ツ)_/¯

Oh, and on the last one, when I confirmed it only had screen burn-in and was otherwise fine, I rooted and flashed Oreo on it
