iPhone and Android difference?

Heya guys, I've been having this weird problem...

For some strange reason, the tapping on my Android is way less responsive than the tapping on my iPhone... In my game, where I squash insects, it takes only around 0.5 seconds or so for it to get squashed when I tap it on the iPhone, whereas tapping it on the android can take around 1-2 seconds before it will shoot the ray to check...

Is there any way to fix this?
