Hey guys,

this is still no kernel, it will only optimize your values for touchscreen using The most important thing in this script is the following line:

Quote:

touch.pressure.scale = 0.001

On my SGS and the SLC is this the best one. Maybe you can try whats working for you as the best and tell it to me so that i can share the best result. I hope the script is now supported by the SGA, i modified it from Galaxy SLC working device... Please give me your feedback.



Can someone of the good Devs from this device tell me if this config is supported by the SGA kernels? Sure it is, but i donīt know under which name



Files attached to this post:
  • the_modified_file.zip (THE mod, RootExplorer method)
  • the_mod_for_galaxy_ace_flashable.zip (THE mod, CWM method)

Files should work now on CM7 and Custom/Stock Samsung Firmwares


How to install:

- RootExplorer method; download the attached the_modified_file.zip, unpack it and put the file to /system/usr/idc/mxt224_ts_input.idc. Aaaand Reboot.
- CWM method; download the attached the_flashable_modified_file.zip, put it to your sd-card and flash it through CWM. Aaaand Reboot.

touch.pressure.calibration = amplitude
touch.pressure.source = default
touch.pressure.scale = 0.001

# Size
touch.size.calibration = normalized

# Pressure
# Driver reports signal strength as pressure.
#
# A normal thumb touch typically registers about 100 signal strength
# units although we don't expect these values to be accurate.
touch.pressure.calibration = amplitude
touch.pressure.source = default
touch.pressure.scale = 0.001



# Orientation
touch.orientation.calibration = none


And why a new Thread?
Very easy. This mod is completely different to my other script. I donīt want to confuse the users ^^

Thanks for posting it. I have one question, I don't have a folder /system/usr/idc. Should I create it?

Installed through CWM, everything seems fine, but I didn't notice any changes.

What do you mean by 'optimize'?
It gives more accuracy, performance or smoothness?
