Hey bud, not sure if you found a solution to this problem as I just ran into myself. I remember when I first bought my note 8 and I had the same problem with my pen. I thought it was just me trying to adjust to new tech! After awhile the issue went away and I realized, now that my pen just broke and I had to get a new one, that the issue is the tip. It needs to be adjusted through wear and tear for the stylus to be less sensitive when you’re trying to write something. I’m playing around with it now and it seems to be working.
