[SOURCE] Improve Touchscreen sensitivity on Galaxy S2 ICS - Galaxy S II Android Development

Galaxy s2 ICS touch sensitivity is too heavy and not smooth (some poppings(?))
here it is solution
it will make touchscreen sensitivity like gingerbread
it need galaxy s2 kernel opensource
open arch/arm/mach-exynos/mach-u1.c (in kernel source)
and find
#define MXT224_MOVFILTER_BATT
default value is 47
it change to 11 (gingerbread default) or 10
and apply this - http://forum.xda-developers.com/showthread.php?t=1161262
for better
and compile kernel
you can feel better touch sensitivity and smooth
it's like gingerbread's touch sensitivity

You guys are imagining things there is no fix needed, i can barley touch my screen like a feather and it can sense it... You don't need any special kernels...

Is it possible to change a config file to access these benefits on a kernel where the change hasn't been entered at compile time?
EG if the mov_hysti fix wasn't compiled into the kernel you can modify /sys/devices/platform/s3c2440-i2c.3/i2c-3/3-004a/mov_hysti
Is there a config file for MXT244?

OP is right. It isn't that smooth. Using dolphin browse when I try to swipe right it pulls left..a lot of the time --_--

Agreed. ICS feels far more sticky than Gingerbread.

it's not a problem of sensitivity, but of filtering small movements
open your phone and type *#2664#
try to draw a very small line (like 3 or 4 pixels)... you can't
you'll either draw 10+ pixels or only 1
but after it "unlocks" (after you draw the first 10 pixels), the movement gets smooth again
(you can check the coordinates in the top)
touchscreentune fixes it, but it seems to be a dirty workaround (need to be reaplied everytime the phone is unlocked)... plus it costs $5, which I'm not willing to pay

can someone tell me the settings in siyah for improving the touch sensitivity?
