I've been trying to find a good stylus to do digital art with an couldn't find many with a fine tip and have been bombarded by S-pen offers, so I'm wondering if they're going to be compatible with my S7, seeing as they're made for Note devices

why would you do digital art on a cellphone

Quicker and more practical as I don't necessarily want to be lugging a tablet around absolutely everywhere with me.

get a surface tablet

drawing on the phone will never yeild even semi professional results. it's doodles only basically

I've been doing okay just using my fingers so far, but I have a galaxy tab too. The phone has been just fine so far, but I use the tab to go into detail.

it doesn't matter how skilled you get the apps and hardware limitations are gonna limit you at some point

Maybe, but I'll wait it out and see.
