Screen problem, pointer's off s-pen position

[nahoku]

Hello all. I had the same issue with my note 4 but had 2 dead spots on the right of the screen and also the pen wouldn't activate apps if the icon was in the dead spot. The phone was in a flip type case with a maget on the back. When I removed the phone from the case the dead spots disappear.

Yes, magnets are a known problem. Unfortunately and ironically, many people still don't know about it.
