Button lag

[Leledon]

I'm playing project diva extend, when I press the touch buttons on android, it lags and doesn't hit the notes accurately. How do I fix it?

Do you have frameskipping on? Frameskipping can introduce input lag.

Try using "Skip buffer effects" in the graphics settings.
The screen will flash during loading screens but the input lag disapears completely in-game.
Turning the display resolution down helps if you get low fps on a few songs too.
