Hi @Spooky Squid Games
Good news! I was able to make some improvements. Upon research devices such as the Galaxy Tab S9 does not have good palm rejection natively, so I thought of a fix that hopefully works for you.
Draw & Pan
In the Pencil tool options you will see this toggle:
For your tablet, I sugest toggling it off. You will then see a Draw / Pan toggle. This second toggle lets you decide if you want to draw or pan / zoom. That way you can work on the preferred mode without interruption. Left is for draw and right is for pan.
I hope this fix works for you. Let me know! Thanks!
