[Q] S-Pen is not accurate topic

Hi, i downloaded a cursive handwriting worksheet to practice with my s-pen, and its terrible to practice on!
and also i noticed that my s-pen was getting inaccurate on the collect button of smart select area, not its just inaccurate in most places ! its around 1mm off at most, but annoying!
anyone knows any way to make it work good again? it wasn't like that when i tried it on store!
at the right bottom cornet its even worst!
