how to improve android touch feel?

why some android device’s touch feel is very bad?
when you want to click some button, but cocos2d-x catch that as a move event, so the user thought that buttons are difficult to tap

anyone knows some silver bullet to fix that problem? on same device, some games are just really better in touch feel! like angry birds, Fruit Ninja att

any idea?
