Comment:

 wow.. Cool Batchyx.

 I was dealing with mouse up/down jitter last week.

 I think this may help palliating your last problem.

 Actually in kernel driver, it calculate the average of some samples within
 threshold and the send to user space.

 If the touch pressure is very light, the data came out from device will be
 very unstable.
