it work for me

[Suxsem]

i love you! i will try now XD

[Suxsem]

it doens't work for me what is your rom?

[Small_Hacker]

I have used this script. It really works and smoother than before. But just works in launcher or home.
I dont think it works in games.

Liquid's touch screen sensitivity is to low to me, even set to high.

After the phone was rooted, I did a `find /sys | grep sensitivity` and found something.

Here we go:

#!/system/bin/sh
sensitivity=25
noise=25
echo "set sensitivity to $sensitivity"
echo $sensitivity > /sys/devices/platform/i2c-adapter/i2c-0/0-005c/sensitivity
echo "set noise to $noise"
echo $noise > /sys/devices/platform/i2c-adapter/i2c-0/0-005c/noise
echo "done"

Default value of sensitivity and noise are 75, I set both to 25 to fit my need.

Haven't find out how to apply this after phone boots, so I made a script to do it manually using Gscript Lite.

Note I only tested it on LiquidE 1.100.05 rom, and root is needed.

This only affects touch screen, but not the 4 buttons bellow(keypad). Keypad's sensitivity can be set from Settings -> Sound & display -> Keypad sensitivity. Set it to high works pretty good for me.

You can download the attachment, rename to sensitivity.sh, put it to /sdcard/gscript/, and add it to Gscript Lite.
sensitivity.txt
Update:
Thanks to malez for pointing out how to keep it permanent under LCR ROM:

adb shell ins_run sensitive.sh "(sleep 90;echo 25 > /sys/devices/platform/i2c-adapter/i2c-0/0-005c/sensitivity;echo 25 > /sys/devices/platform/i2c-adapter/i2c-0/0-005c/noise) &"

Hi im sorry for being a noob here. I've rooted my liquid to 1.100.05. I just dunno how to use this sensitivity script. I've added to Gscript but i dunno how to "activate/run" the script cause when i try to run in Gscript i just got a blue screen. Also what is "LCR"? I tried to use cmd and this is what i get. Im using windows 7 by the way.

Again im so sorry for asking noob questions! But how do i use the script? Thanks.

Rename the txt file to sensitivity.sh

Put that file on your sdcard in the folder for gscript.

Run gscript, and run that sensitivity.sh file.

Btw from what I understand, you hafta do it on every boot. Some custom ROMs have it built in and malez provided an update.zip file if you use LCR.

In the blue screen, you should see this output:

set sensitivity to 25
set noise to 25
done

that means values are successfully set.

LCR means Liquid Community ROM, see here http://android.modac...-v1-6-18-05-10/

If you want to keep it permanent, you have to flash a custom ROM, like LCR, Xian, Batista70phone. Some custom ROMs already do this for you(and no one mentioned me except malez ), check the changelog, if sensitivity is mentioned, then you just need an update.

What does noise mean here?

[Azzay]

It's basically the same like with audio noise - it's an unwanted phenomenon (caused by errors/inaccuracy in your sensors/gains or e.g. capacity changes in your environment). Practically it limits the detection of small signals.

So the filter-value here seems to be a filter that removes signals smaller than a given strength (so only your fingers get detected ).

Btw: Great work azuwis

Does it mean that I should turn the value of "noise" to be smaller if i want the screen being more sensitive?

The noise as well as the sensitivity (afaik). Don't go too far though or you'll get random "touches". I believe 20 is as low as you can go.

I have tried the new version one that is 20/50

It is really better and have a big different against the old one

[drigerott]

try this 30 sensitivity 75 noise ^^

you will have high sensitivity and high precision

[wu chung yi]

is the higher values of noise mean the higher precision?

[Morris Lee]

This is awesome, mine is like iphone sensitivity now, but did anyone experience that from time to time, the whole screen is just going crazy and pressing everything?

[Koki1337]

Just ran the script with my Liquid E on baseband version A1-04.04.02!
Works great, and I must say this is a thumbs up!!!

@Morris, it does, same problem as mine, that's why I used this script. I changed sensitivity to 75/75.
Does the noise actually control the background particle movements? I mean, I want to use 25/75 if that's possible

25/75 still does not help, heck, 25/100 still goes crazy!, 50/75 does too. I still can't pin down what is actually causing the interferences to the random touches. I tried to see if it is the internal components by judging the amount of time I have the phone on, if the palm in the back of the phone affects it more, still, no actual direct differences at the moment.
