I replaced my display with a new note 5 display, that i got from fixit. all works fine with the finger. Only the s-pen works in a few areas of the display. is the s-pen broken or is the display itself not ok? how can this be explained? also the return and the window button work but don´t glow anymore.
For the S-pen issue. That sounds like an LCD failure. The S-pen wouldn’t work at all on the screen if it were the S-pen. As for the soft keys at the bottom, make sure that the bottom PCB is connected properly and that you don’t have power saving mode turned on. Also try a factory reset and if that doesn’t work try flashing it. If that still doesn’t work then it might be a bad PCB at the bottom there. You possibly damaged the buttons when removing the LCD. It happens all the time for me at work.
