Touches not registering in android?

I've been trying to update my app, but I noticed something weird

This code: if (Input.getmousebutton(0)) Doesn't work, I figured that it was just wibbly wobbly on touch screen devices, so I did this if (Input.touchCount > 0) I got desperate, so I created a button for it, but that didn't work, it just didn't react to the touch.

I've got to figure this out soon, and I've got no device to test on (besides my nexus 7, which for some reason I can't run anything on). Help?
