I have a Samsung S8 Ultra and I've finally figured out how to use the stylus to add notation to a song. 
One issue I can't figure out: Tonight I was adding notation to a song (using stylus) and I took a break. When I returned to add more stuff with the stylus, I saw that lines/curves were added to the song as the stylus hovered near the tablet. (It wasn't touching the tablet.) It wasn't doing that before when I was entering notation.
Any idea what causes that? Is there a setting somewhere that controls interaction with the stylus?
Thanks.
Linda
