The screen sensitivity on the Prime in conjuction with a stylus absolutely sucks and thats no joke. I'm not talking about clicking icons and swiping screens, I'm speaking of writing notes and drawing. ABSOLUTELY SUCKS. No joke.
This can be remedied quickly with an app called TouchScreen Tune available on the PLAY Store. The full version will cost you $5 but i promise you it is money well spent. After you adjust the sensitivity, you can glide the stylus across the screen in the lightest fashion you want, without applying pressure at all. Excellent excellent excellent.
It increases the functionality of the Prime dramatically. You'll be able to write and draw like no ones business.
The lite version of TouchScreen Tune is free and please note your tablet must be rooted for the app to work.
Run, don't walk to the Play Store now and download the lite version. If you don't like it I'll give you your money back.
