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/show....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 --_--
