How to make my touchscreen better on Tab Pro 12.2

After bricking my tablet twice , today i was finally able to root it . Unlike other people , the reason why I rooted it was to "decrease the minimum duration of touch to almost 0 " , by that i mean , make the touchscreen as responsive as the one on a phone . I am used to tapping the the touchscreen really really fast , barely even touching it which works on my phone , but it doesnt work on my Tab Pro 12.2 inch most of the times . The default minimum duration of touch is low i guess but def not low enough . I want my taps to be registered no matter how fast I tap the screen or the intensity at which I tapped it . Yes this is my first time rooting an android device so I am not very familiar with it. I am not a tech noob though , I already learnt a lot of things about rooting .

This is the article that motivated me to root my tablet :
I need to have 10 posts to post links it seems

So I did what it was in that article , I modified my build.prop and added this code :

# Touch screen calibration and scroll responsiveness
debug.performance.tuning=1
windowsmgr.max_events_per_sec=200
view.touch_slop=2
view.scroll_friction=1.5
view.minimum_fling_velocity=25
ro.max.fling_velocity=12000
ro.min.fling_velocity=8000
ro.min_pointer_dur=8
touch.size.calibration=geometric
touch.size.scale=100

#touch.size.bias=70
touch.pressure.calibration=amplitude
touch.pressure.scale=0.3

Then I rebooted and again , no change . My screens accuracy and everything else is perfect , the only thing that is not perfect is the thing I already mentioned , so I anyone knows how to make my screen so sensitive that it reacts even if a hair touches it or even if i barely touch with my finder with the speed of light , it registers the touch . If possible of course .
