Touchscreen is too touchy

[pachuco]

In android version, when touching screen, triggering of next touch event happens almost instantly. No delays. Thus I get cases where I accidentally press button on next menu screen(unless I shift finger slightly) and worse, being unable to exit menu ingame(retriggers instantly).

Suggestions:

• Maybe a grace period before processing next touch.
• Track finger and reject its touch events until it has been lifted from screen.
