What I suggest you is to try to keep pressure. touching / softly moving the finger will always be a click (as the first touch is generating a UP event) that represents the click. So try experimenting with a little more pressure.
Film perforation idea : no ways : / sorry, it's just out of our vision for it ;/
I'm sad that you are having this problems, we will keep studying (not messing the released source) trying to improve this click rate success (for all cases)
