I can help with this
!! So a while ago I wanted to use my tab for writing and I got all of these apps to use as notebooks and I totally forgot about the idea. A few days ago while going through the top paid apps I noticed this app (link
) and I totally forgot that I purchased it a while ago. While reading its description, I noticed that the dev said:
"Galaxy 10.1 owners: You must have root on your device and use TouchScreenTune (free app that fixes your touch screen sensitivity). Otherwise the writing will lag.
So I checked out the app (which is free and requires root) and people were praising it on how it works and how it makes stylus use a much more pleasanter overall experience through a lot of apps. Good luck and let me know how it goes! I haven't tried it since I don't want to root my tablet for now.
