Hello, since yesterday I started having problems with the touch screen ... to see if I can explain what is going right....
I can not write using the "q", "t", "f", "v" and "shif" and everything else that stands in (and this I presume) two vertical stripes where the touch does not seem work ...
Anyone else had this problem and knows how to solve it, or do I have to send the phone for warranty?
Thanks in advance!
have u tried to install a diferent keyboard app? or maybe clean data from original keyboard app?
yes i had miui installed when it occured then i've downgraded for official 2.3.5 and the problem remains...
I think i'll have to take the animal to the doctor...
Had a similar problem on mine, the right 1cm of the touch screen didn't work. I replaced the touch screen, problem solved.
Hi All,
I have a dual monitor setup with one touch and one non-touch. The problem that I had was in-order to make my touch screen work I had to make it the default. I did not want that as my other monitor (non-touch) was larger. I have been searching all the various forums for a solution. I found it on the Surface Geek web site. The instructions follow:
-----------------------------------------------------------------------------------------------------------
So, I know that you guys are going to think I am crazy, but I recently bought a new machine that has a touchscreen. I had already bought a touchscreen for my old machine and decided I wanted to go dual monitors with each a touchscreen. I found an interesting problem. It appears that Window 8 sees the touchscreen input differently than the monitor. Sorta makes sense, how is it supposed to know which touchscreen goes to which monitor. I looked on the web to see if I could find a solution and nothing could be found except others complaining about this as well. Well, I am happy to say that I figured out how to associate the touchscreen of each monitor to the correct one.
You have to go into your control panel. Click on Hardware and Sound. Click on Tablet PC Settings. Click on Setup under Configure your pen and touch displays. Then you have to touch the screen that is showing the text. Click OK or Next and then click the next one when the words come on this one. This allows the computer to know which screen is which screen. Otherwise it appears that it just thinks that both are one. Hope this helps.

I dropped my phone and cracked the screen. So since I've did that, the touch screen doesn't work. I went to get the screened replaced and went to test it out and it still doesn't work. What's not allowing my touch screen to work after getting the screen replaced? If I change the screen does is the digitizer attached to the screen so therefore it will get changed too or is it a separate hardware?
Most likely faulty replacement part.
Try downgrade to 4.2.2

Hi, I've purchased a cheap diplay at ebay. Touch didnt work any more.. after a number of tests i found out this was due to a HW test at boot. When downgrading 4.2.2 everything works fine. Any upgrade 4.3+ failed to enable digitizer after reboot.
PS: When booting eg 4.4.4 with the old digitizer connected and then connect the new digitizer w/o rebboting the the touch was working well.. I'm very interested in geting a confirmation or reason what causes this issue kindly keep me posted
Most replacement screens use an original LCD (recycled from a cracked screen) fitted with a copy touchscreen. Either the incompatibility could be deliberate on LGs part but I think it's probably due to a driver update or something which has broken compatibility with the reverse engineered touchscreen. It could also be a coincidence, some copy parts are prone to just not working for no real reason sometimes.
Hey DrFredPhD
Can you imagine a costum rom with the old touchscreen drivers from 4.2.2 into 4.4.4?
What would this require: To compile a costum kernel? The drivers would usually be in compiled form in the boot.img, right?
I've tried to flash 4.4.4 with the old boot.img from 4.2.2. - but the phone didn't start (as expected..)
Can you imagine someone how could help me in this regard? I think there may be a number of people facing the same problem..
Anyway, thanks for your help - Greetings :good:
Binaries are available for nexus 4, maybe compiling from AOSP with older binaries would work, but you might break functionality too.
It's been done on other devices but probably not for the reason you want.
https://developers.google.com/android/nexus/drivers#makojdq39
So what are you essentially saying? Put the mb in a good working nexus and see if it works or that maybe the tech put a new digitizer with the old rom driver onto an older mb with a new rom driver? And that could possibly cause conflict with drivers or roms? Which in turn will not allow my screen to function?
The part he put on is crap, if you put a decent replacement screen on it'll work fine.

Are you sure? Because I don't wanna regret spending money on a new screen and it doesn't work. :laugh:
I've seen phones damaged by a repair bad enough that the touch will never work, but I've seen far more copy touchscreens that are useless.
Hi Guys
Just to say: may bad fake faulty touch "per se" works well under 4.2.2 and updated 4.4.4 also! It just prohibited "start" the phone with this digitizer attached! Both, phone and digitizer are fully functional and "compatible"..
Hi Folks, Firstly I know I have been very stupid. Please don't make me feel worse than I already do. I have read through this board and after feeling like I was about to give in trying to fix my Chinese GPS I have a bit of hope. I bought the unit as working from ebay and decided (stupidly) to flash Mio Pocket after a guy on a car forum sung its praises. I initially meant to run from the sd to test but I accidentally clicked install and it did its thing then froze on reboot. After rebooting it was just stuck on the screen saying Welcome to Navigation. I have measured my screen, it seems to be 6.5" measured diagonally
I found a chinese site and have tried all the firmware on there, it all seems to restore my original GPS side of the software but the screen is the wrong resolution and too low on the screen. I can just about calibrate it by poking my nail down the bezel for the lower calibration points but then when I select the navigation source selection screen I cant see the files as they are off to the left (off screen) I tried using the remote to no avail. I have also tried the 117_nav_en.exe floating around on the internet which again seems to be the right software but the wrong resolution. My problem is that I bought the unit off ebay and I don't know the brand or model number to contact support. Neither does the seller unfortunately (it was used)
The unit is for a Skoda / VW it has GPS, BT, TV Tuner, 2 x sd slots (one for nav one for media) and an iphone input on the front. It has the car door open indicator pictures etc and the non ce side of things is still working fine.
I am reasonably confident that the firmware I have tried so far is for bigger screens than my 6.5" and hopefully if I can find a firmware version for this size I should be ok.
I have included an image of how it currently looks
I really hope someone can help me
Thanks for reading
