Is there an easy way to remove the android home buttons at the bottom of the screen on scroll down and appear again on scroll up?
There is currently no way of doing that, at least not out of the box with UX.
It could probably be achieved using Uno/Foreign Code if you’re not afraid of writing some Java and Uno (as long as this is actually something the android api supports).
Just wanted to clarify that its not the “do something on scroll up/down” part that is the problem. It’s triggering the bottom bar to actually go away that we don’t currently support.
