I briefly used it on Android. The scrolling momentum was all wonky, totally different from the rest of the system, and using it was unbearably unpleasant for me. I resorted to digging into developer menus and manually tweaking parameters, trying to get it to feel remotely good, and eventually I gave up.

I don't understand why they would make it so, but that's the sole reason I stopped using it, despite being otherwise willing to go out of my way to support them
