----
I think it's kernel issue.

the kernel module of touchscreen almost same between OpenEtna and OpenEVE and 
it somewhat older.

is there any working calibration app exists for GW620/KH5200 ?

Original comment by wkp...@gmail.com on 11 May 2011 at 10:16

All I know is that the original 1.5 firmware had the hidden menu, and inside 
there was an app to calibrate the screen.

In Froyo officer has the option to calibrate the screen display settings if I 
remember correctly.

yes. Official froyo support Touchscreen calibration. but I mean opensource 
repaclacement of TS calibration.

----
and TS calibration of GB is somewhat different with froyo.

froyo use tslib but GB doesn't.
----
this is deodexed and slightly modified HiddenMenu.apk
you can use HiddenMenu2.apk like as following method.

 adb install HiddenMenu2.apk

1651 KB/s (4189508 bytes in 2.477s)
        pkg: /data/local/tmp/HiddenMenu2.apk
Success

------
not all of functions of HiddenMenu2.apk are available but
the ts calibration is just works fine.

after installation, you have to register icon of hiddenMenu like following 
method.

menu key => (+) add => Custom shortcut => "pick your activity" => "Activities"
=> "com.lge.hiddenmenu" => "Calibration(.device_test.touch_test.TSCalibration)"

after then you can use the tscalibraion.

and this is not means that the calibration of Touchscreen is working correctly.

Thank you.
Did it.
Hope the calibration gives me the right result. :)

I got the calibration menu installed, however when you run it it says "out of 
range, please try again" even when you press dead in the centre of the 
target...

TScalibration of hiddenmenu2 does not calibrate the screen (yes, i know how it 
works and how to calibrate, I've done that many times in off.froyo).

btw: if you choose this:
menu key => (+) add => Custom shortcut => "pick your activity" => "Activities"
=> "com.lge.hiddenmenu" => "Device Test(.device_test.DeviceTest)"
and go to "Touch test" there are some options to check the calibration such as 
finger paint, etc...

kuroneko // Use a Pen (:

PHONE SLOWS DOWN IN SPEED AFTER INSTALLING HiddenMenu2.apk !!!!

Original comment by Katzen...@gmail.com on 12 May 2011 at 7:31

[GoogleCodeExporter]

So if you can make a custom shortcut for this, is it possible to make such a 
shortcut to access the Testing menu (*#*#4636#*#*)?

Original comment by rais...@gmail.com on 13 May 2011 at 12:17

[GoogleCodeExporter]

@rais // yes some menu can be acceded by this method. not all of them

i have found some bug/misconfiguration at the touchscreen driver of kernel.

it is not properly initialized.

so trial and error to find out right value. I can get more reasonable result.

these are before/after imgs.

 * test method : try to pick the crossed points of grid with a sharp stylus pen.
 * ts_before : uniformly scaled up.
 * trial and error : increase maximum value and decrease minimum value step by step
 * ts_after : that's it!
----
 * remained issue : blind spot exists at the lower y / lower x regions.

above (comment #16) fix is only work correctly with my phone :(

it is not easy to fix it.
we need some calibration feature or workaround to fix this issue.

is something in cyanogen github/repository?

Original comment by Katzen...@gmail.com on 13 May 2011 at 9:38

Then there is always moduleap.apk, but to be honest, I have no idea what it 
does.  The error message is supposed to be normal.  Maybe it is only for a 
specific capacitive touchscreen.

i used that too in the past. ;)
i think there are no changes. try it.

wkp - I figured out how to make the shortcut I wanted, Shortcut - Activities - 
Settings - Testing (com.android.settings.TestingSettings) :D

Katzen - I also didn't see any real difference with moduleap, I haven't had any 
major calibration problems though.

this is unmodified just deodexed HiddenMenu.apk and it also works fine.
you can install it by "adb push HiddenMenu.apk /system/app/"

Sorry what is the difference between this file and the one you uploaded 
yesterday?

Also, do I have to uninstall the one from yesterday first?

Last, can I install this by opening the apk file, or do I have to put it in the 
/system/app/ folder?

Thanks wkp!

@rais // you have to uninstall HiddenMenu2.apk first, then "adb push" or just 
copy "HiddenMenu.apk" into /system/app/.

but i only think that its better now.

Thanks wkp, I'm going on vacation for a while so I won't be able to report back 
for a bit.  I'll test this out!

HiddenMenu.apk can do nothing for GB2.3.x :p it's only for testing.

Calibration menu makes /data/misc/ts_cal used by Official Froyo for TS 
calibration.
but it is not used by GB!

currently GB does support Touchscreen calibration at all.

Original comment by wkp...@gmail.com on 14 May 2011 at 2:04

I found this calibration tool 
 http://www.mediafire.com/?e47aloxaujxo2o1
It's probably pulled from a lg gt540 rom and it's interface is the same but it 
doesn't give "Out of range" error. So if you can get GB to use ts.cal we should 
use this app cause it's much easier to use and you don't have to create an 
activity shortcut.

Original comment by omarbeko...@gmail.com on 14 May 2011 at 4:22

[GoogleCodeExporter]

is that a distributable app ?

it is known that HiddenMenu.apk is distributable
(you can see this information at /system/etc/NOTICE.html.gz of Official LG 
froyo)
----
LGCalibrationTS.apk must be resigned correctly. it saves ts_cal into the 
/data/nv/ but have no permission.

----
and TSCalibration.apk also works too.
https://github.com/CyanogenMod/android_packages_apps_TSCalibration

but it is not good enough I think..

I had this issue a couple of months ago, intermittent at the beginning. Same 
problem with official 1.5 or opentena. This was due to a moisture / waterproof 
quality of the phone. I had it serviced, and they changed the touch pad and the 
covers, and everything has been ok since.
