Ah shit, I thought it had reverb but it doesn’t seem to :(, my bad.

Get any equalizer app (e.g. Poweramp Equalizer).

BTW that still uses Google’s proprietary gesture typing library internally: https://github.com/wordmage/openboard/commit/46fdf2b550035ca69299ce312fa158e7ade36967

There’s still no good FOSS alternative to Google’s library though so it is what it is.

No, you want it for scrolling. Scrolling feels much more responsive at 120Hz. It does drain battery more but not by enough to be a deal breaker for most people.

It’s useless for videos as most videos are 60Hz.
