Hi all,
I have replaced touch layer in my hd2 and buttons. Everything was great, but sometimes HD2 has very strange behavior. For example, Iam at home screen, just scrolling thru apps, when suddenly touch layer starts to recognize touches in upper part of display. This can happen even when I dont have any fingers on phone ... If I want to stop this I usually put multiple fingers on layer, or just go to lock screen. So Iam wondering if my touch layer isn't somehow broken, or if is there any short circuit or something else? Do anyone of you have same experience as me?
Thx for all tips

Hi,
I just want to thank everyone on this site for the plethora of information that is available.
Here is a rather strange issue, that I did not see covered previously...
I purchased a used aria with a cracked digitizer off ebay for pretty cheap. I replaced the digitizer myself and all was good. I used the phone for about a week and dropped it. After that, the digitizer has been acting a bit flaky.
For instance, when it decides that it wants to annoy me, every input seems to register only on the middle of the screen. For instance, if I touch the top of the screen, the screen registers touches as though I was touching the screen in middle of the height. If I touch the bottom, it still registers the touch in the center of the screen.
I found that If I knock the phone against a table, along the edge, the problem goes away for a while. Then it crops up, again, randomly.
Anyone have this issue?
Thanks,
JC
Hello
I have 2 months old LG Nexus 4 and I have a problem with touch screen. These is a field in a buttom of the screen whitch is not reacting on touch. I ca touch it 100 times and nofthing happens it is not respondint to anything even harder touches.
so the field is here
shrani.najdi.si/?2k/2D/4dhib9sI/screenshot2012-11-04-14-.jpg
under these field and above is screen working normaly. now i want to know if is these maybe a softwere bug or is these a hardwer one and i should take the phone on the serverice, btw the phone never fall or anything else.
Thank you for advices.
Try going to developer options, enabling here "Pointer Location" and then swype across the screen a few times so there will be a long blue line (it's important to move your finger on the screen near that faulty place). If your finger suddenly stops drawing that blue line then it's definitely a hardware problem.
Now I know this problem has been asked before but after some extensive searches I can see there are no clean fixes for this.
My Nexus 4 (Android 5.0.2 LiquidSmooth ROM) has started showing ghost touches at the bottom part of the screen. I know there are a lot of explanations available such as digitizer not working, battery being too old etc. But I'm not interested in these hardware issues/fixes.
I have isolated the area of effect as the bottom ~160 pixel height of the device. I then proceeded to use the ADB shell command
wm overscan 0,0,0,160
which removed that portion from the UI. This fixed the effects these phantom touches have on the apps or UI. But a problem still remains that these ghost touches happen in too many numbers and this leaves other usable areas of the screen insensitive to touch. I am guessing this is due to the multi touch limit being reached in that bottom unused part itself. Multi touch testing apps dont pick up touches on the top part of the screen
So my question is, is it possible to remove a part of the screen from the System itself? Ideally a thick black bar of unused area, leaving me with a shorter yet fully working screen? Or atleast is it possible to turn off touch response in that lower part of the screen so that it doesnt max out the multi touch limit?
My Nexus 4's is same too
I think, that ghost touch will work from Screen Digitizer. My Nexus 4's screen digitizer was non-LG's digitizer, it was fake. I need to change that digitizer
I workaround this issue avoid using undervoling in the kernel, and avoid lower temperatures in phone, yes as you read ... this issue give my crazy when my phone was to hot and I tried to cold my phone using one ice cube in screen and back, the temperature of the phone down but ghost touches appears again, so played some videos to warm the phone again and dissapear again.
Don't ask me about how it works, or relation with screen, digitizer or battery, I don't understand but help me to workaround the issue.
Hi ppl my E7 start giving a few toutch screen problems a few days ago. At fist it start unlocking the screen and opening apps and doing calls on its own when on my pocket what it never did before since i bought him months ago. The when i was playing heartstone the toutch screen become totaly crazy no leting me do any grab and drag options e clicking screen at randow :S After a few turn screen on/off it become ok again.. But after a few minutes it hapend again :S when form tha moment it was never the same.. sometimes stops from responding other can do the drag up action to unlock screen others cant drag items others it just starts clicking like crazy on screen on its own.. Had a few power on/off.. Problems continues.. Had a factory reset problem seem a little better but not much.. juxt stop clicking on its own now but cant do drag actions across full screen. Now i installed a toutch screen test app. Found that a part of the screen is not responding (or is responding really really bad like a dozen pixels only in a finger from top to buttom size area) in a paint test... the lenght of a finger.. from top to bottoum near the middle screen (Landscape mode). Cold it be a software issue on the rom ? i did installed some suspecius software (im rooted) a few times could it have damage the rom or the touch drivers or controls in a way the reseting it wont fix? could installing other rom fix it ? Could it be that the screen got out of calibration or something like that ? or its really an hardware issue ?
if its hardware is it cheaper just to exchance the touch screen since the screen doesnt have a single scrach? Or replacing the touch panel is the expansive part when screen breaks? Please any idea is welcome even if little help. Thx for any answer in advance and sorry for my bad english :S im Portuguese
I've searched a good bit and wasn't able to find any information regarding the exact problem I'm having.
Bought a used G6 for starters
No water damage indicated by the sticker
The phone works great on the home screen and app drawer
I turned on dev mode to show touches
When you're in the camera it will stop responding to touches, you can still take pictures using the side buttons. The screen will become responsive again after a couple minutes. This whole time you can take pictures and the screen is functioning just not responding to touch
This happens also when you're loading web pages, even a Google search the screen will stop responding to touch and then eventually start responding again for a short while till you load another page or start moving around the page too quickly it seems. However again the screen is functioning, video previews are playing, just no response to touch.
Loading a game like Asphalt 8 the phone doesn't respond to touches until a couple minutes after the game has been fully loaded.
Even after a hard reset/factory reset the screen will sometimes be unresponsive upon the initial welcome/setup screen and then it will become responsive and you can go through the whole setup without an issue.
Any insight? Any suggestions? If I can't figure it out I'll just get rid of it but it's in great condition a shame it just doesn't function properly.
Thanks in advance!
Looks like some sort of hardware issue...
But before you start to worry...
This might sound like a stupid question but have you tried cleaning your screen with some cleaning solutions?
Sometimes dust mixed with dried sweat can cause severe touch responsiveness issues even if the screen looks like it's clean.
This is an older thread, but maybe I can help someone.
I replaced a touchscreen on a LG G6 and saw that the touchscreen did not work if the back cover was not mounted correctly and the data transfer between the phone and the fingerprint sensor was interrupted. This may be a common problem for users because the connector is small and the back cover is attached with a double-sided tape nearby this connector. It seems that the touch screen is disabled by the phone software without the back cover.

Thank you so much for this comment!
My gf phone had problems lagging and becoming insensitive to touch, the problem got worse and worse, almost never responding anymore. Performed a factory reset etc, didn't help.
After reading your comment I tried pushing on the back cover while swiping. Now I'm able to revive the phone after pushing hard on the top and bottom left corners, of the back cover.
Thanks a mille !
Lg g6 has back panel from glass and under it you have contact for fingerprint sensor.Somehow if the back panel is loose it can cause touch fail,and you cant use the device touch function!
--->FIX:
So you will have to turn screen off using back button,and then try to press back glass on left and right side of the camera lens !
Then simultaneously press the power button and try to use the touch .
If it does not work tru again around camera lens and turn off screen each time you press the back glass!
For me it worked !
