I justhink bought the Galaxy Note 10.1 2014 and I noticed an interesting feature in some of Samsung apps. When you are using the stylus pen to write or draw, it won't be interfreed by the wrist that is over the screen. I also just bought the ps touch and I think it would be useful to have a feature like that. Because it is really hard to paint with the S pen withoUT touching the screen with the hand. Imagine you are trying to write something in your notebook, but your Palm is Covered in fresh paint. It would mess the whole paper, wouldn'the it?
I hope it's an easy thing to implement. I'm a programmere myself, but I know nothing about Android and Java.
I loved your app, keep developing it. It's very useful when you are away from home or work.
I believe the term you're looking for is, "palm rejection." I think there are a handful of apps that do this.
I agree wholeheartedly that PS Touch is very handy when you're out and about.
