Guest ShMaunder Posted February 15, 2011 Report Posted February 15, 2011 Hi Guys, I would like to thank the members on this forum for their newbie guides on flashing to Froyo - very helpful :D Anyway, I have a problem with the touch screen. After a lot of searching around; my understanding is screen calibration isn't possible/provided with CM? A lot of users have used a keyboard calibrator to fix their issues. I've installed Smart Keyboard Trial and calibrated it - this has fixed some issues with the keyboard. My problem is with the general usage of the phone - the screen is about 5mm out of alignment on the top and bottom though fine in the center. Pointer location reports that the Y axis is at -25 when i touch the top of the screen - i guess the phone thinks 0 is the top of the screen. Are there any work arounds or solutions that i've missed? Thanks
Guest wyeko Posted February 15, 2011 Report Posted February 15, 2011 HM, I think i have the same problem.

Guest AerospaceMango Posted February 17, 2011 Report Posted February 17, 2011 credit to fishears for the link: http://www.mediafire.com/?e47aloxaujxo2o1 Does anyone know if this works with 2.3??
Guest Dr.Alani Posted February 17, 2011 Report Posted February 17, 2011 Does anyone know if this works with 2.3?? I used it in CM7 (2.3.2) and it worked perfectly.
Guest AerospaceMango Posted February 17, 2011 Report Posted February 17, 2011 I used it in CM7 (2.3.2) and it worked perfectly. Cool....I shall be doing that then!!
Guest Loginer Posted February 17, 2011 Report Posted February 17, 2011 My touch screen has been insanely uncalibrated ever since I first installed OpenSwift -- clicking on links near the top or bottom of the screen is practically impossible -- and I've tried using this calibration app on both OpenSwift and SwiftDroid. It does nothing. I've created the data/nv folder (yes, there's a file called "ts_cal" in there now), rebooted several times, tried both pushing and installing the app, all to no avail. It's possible that my touch screen's defective in one way or another, but I'd imagine there'd still be some sort of noticeable difference after calibrating. I'm more inclined to believe that this app currently does nothing on anything but LG's firmware/kernel; any minor improvement in accuracy some of you are noticing is probably a placebo effect.
Guest ShMaunder Posted February 17, 2011 Report Posted February 17, 2011 credit to fishears for the link: http://www.mediafire.com/?e47aloxaujxo2o1 Thanks for the link - though this hasn't fixed the problem :D Is there anything else I'm suppose to do after installing and calibrating?

Exactly the same as me. I just added the nv directory and now have ts_cal, though no change. I don't think i've got defective hardware as the axes on Pointer Location precisely follow the touch screen into the minus figures. Plus this was only a problem the moment i upgraded to CM. Though i would say that the top is by far worse then the bottom. If i get a chance tonight, i will upload a video on youtube showing the extent of the problem. Cheers all.
Guest ShMaunder Posted February 17, 2011 Report Posted February 17, 2011 I have uploaded a video to Youtube here: http://www.youtube.com/watch?v=IbBplFkyko0. Its pretty bad, though it does show the effect I'm having. Would be interested to know if anybody else has something similar to that?
Guest ShMaunder Posted February 28, 2011 Report Posted February 28, 2011 Bump.... I've tried flashing with CM 7 (2.3), reinstalled the calibration tool with /data/nv directory and it still has the same result. For now i've gone back to LG's 2.1 where the touch screen calibrates perfectly. Though its soooo slow compared to 2.2 or 2.3 :huh: Surely somebody knows how to fix this :)

Its pretty bad, though it does show the effect I'm having. Would be interested to know if anybody else has something similar to that? I have the same problem. I guess most GT540's have "standard" calibration settings for their touchscreens. Unluckily for some of us some mobiles have some "deviation" from the factory standard. I use the "Multitouch Visible Test" app. (Source at: http://www.rbgrn.net/content/367-source-co...h-visible-test) It tells me that there's a 25px difference at the right edge of the screen. This is what the "Screen Calibration" app reports: #cat /data/nv/ts_cal 58451,6,61465,18,65536[/codebox] I'm curious about what other users are experiencing. Any idea on how can we help solve this problem?
