I know the answer to this problem. I removed apps, restarted a bunch of times and after speaking to Samsung support, who told me to do a factory reset, which I did :( The answer is…change your S Pen stylus tip. I went ahead and changed the tip and all of a sudden, the problem has completely gone away. Hope this helps you. I love my stylus and it not working was driving me crazy. Now everything is great on my Note…as usual.
