Guest azuwis Posted May 25, 2010 Report Share Posted May 25, 2010 (edited) 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 sensitivity.zip, unpack to get sensitivity.sh, put it to /sdcard/gscript/, and add it to Gscript Lite. 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) &" Update2: Now I set values to 20/50, feel these're better. Change the values according to your need, use a unix compatible editor(notepad++, gvim, etc) to edit the file. Update3: Root is NOT needed at all. If the phone is not rooted, uncheck the 'su' checkbox in Gscript Lite. Thanks to Azzay for the feedback. old sensitivity.txtnew sensitivity.zip Edited June 12, 2010 by azuwis Link to comment Share on other sites More sharing options...
Guest nameless' Posted May 25, 2010 Report Share Posted May 25, 2010 Seems nice, did you noticed a big difference ? Thanks for the tip anyway, will try it tonight :rolleyes: Link to comment Share on other sites More sharing options...
Guest natostanco Posted May 25, 2010 Report Share Posted May 25, 2010 (edited) with this script capacitive stylus works! but not for the 4 buttons :rolleyes: Edited May 25, 2010 by natostanco Link to comment Share on other sites More sharing options...
Guest azuwis Posted May 25, 2010 Report Share Posted May 25, 2010 Seems nice, did you noticed a big difference ? Thanks for the tip anyway, will try it tonight :rolleyes: Yes, huge difference. My Liquid is a black one, screen is covered by screen protector from official Acer(Does this make sensitivity low?). When touch panel sensitivity was set to high(default value 75), I have to press the screen to make it move. Now I only slightly touch it, and it responds to me quickly.

Guest natostanco Posted May 25, 2010 Report Share Posted May 25, 2010 yep now can scroll with fingernail too, without this script was necessary the fingertip instead :rolleyes: btw sensitivy for the 4 buttons is still the same as before, at least it seems to me :D Link to comment Share on other sites More sharing options...
Guest ondris Posted May 25, 2010 Report Share Posted May 25, 2010 Wow it's amazing! Very nice man! THank you. And I also notices thar for the 4 buttons the sensivity it's the same, but this doesn't matter :rolleyes: Do you think we can even change the values to lower ones?

I tried 10, but it made touch screen unusable. You can try 20 or 15, and see if it works for you. Link to comment Share on other sites More sharing options...

Guest chingy1788 Posted May 25, 2010 Report Share Posted May 25, 2010 I'm still a novice at linux, and the inner workings of android/linux but I looked into this dir /sys/devices/system/cpu/cpu0/cpufreq would changing any of those values do anything?

Guest Quipeace Posted May 25, 2010 Report Share Posted May 25, 2010 Isn't that what apps like setCPU do? The tweak works great by the way, thanks :rolleyes: Link to comment Share on other sites More sharing options...
Guest jayziac Posted May 25, 2010 Report Share Posted May 25, 2010 (edited) Does this affect battery in anyway? I'm no expert in capacitive touchscreens, but I wonder if increasing sensitivity increases the sensor polling rate or the voltage it applies to measure touches? I noticed more sensitivity when I replaced the screen cover that came with my liquid with a cheap one bought on ebay that seemed thinner. I'm mostly using low sensitivity now, high would probably be enough for me. But it's nice to know I can go even higher if need to.

Guest barmyman Posted May 25, 2010 Report Share Posted May 25, 2010 (edited) wooow!!! works really great!!! Thanks!!! btw,maybe you are able to enable normal multitouch like on Milestone? Edited May 25, 2010 by barmyman Link to comment Share on other sites More sharing options...
Guest malez Posted May 25, 2010 Report Share Posted May 25, 2010 Thank you for this tips. If you want to keep it permanent under LCR : adb shell ins_run sensitive.sh 'echo 25 > /sys/devices/platform/i2c-adapter/i2c-0/0-005c/sensitivity ; echo 25 > /sys/devices/platform/i2c-adapter/i2c-0/0-005c/noise' adb reboot If you want to change value, use exactly the same commandline using different values. If you want to disable it : adb shell rm_run sensitive.sh Link to comment Share on other sites More sharing options...

Guest markII Posted May 25, 2010 Report Share Posted May 25, 2010 Sorry ,what I mean is if you know the method to do the same for stock rom ^^ Link to comment Share on other sites More sharing options...
Guest malez Posted May 25, 2010 Report Share Posted May 25, 2010 (edited) Sorry ,what I mean is if you know the method to do the same for stock rom ^^ I have developped ins_run for lcr. It can't be done on stock. But LCR 1.6 is faster than stock, and much more. .. do a nandroid backup, try LCR 1.6. If it does not satisfy you (sure it will), restore your backup On stock your only solution is to run a gscript manually after each start.
