Touch screen stopped working :-(((

Hi,
The touch screen part of my universal has ground to halt to the point that it won't work.
There doesn't appear to be any cracking and I don't recall dropping it or sitting on it.
I work a fair bit outside and can get quite a bit of dust and dirt in my pockets and am wondering if it could be due to dirt getting into the connect on the hinge.
Has any one else come across problems with the hinge?
I'm reasonably adept with a screwdriver - are there any things to watch out for when disassembling to check it over?

Hi..
If u can open with the Universal guide posted in the forum then try clean ing the connectors on the Right and Left of the Clamp Shell part with Iso Propyl Alcohol.
Before opeining you can try pressing mildly with yr fingers, at all the forur corners..it can start working..else do the above...

Hi,
OK, the screen seems to be working OK this morning, however I seem to be getting a sort of ghost effect where it appears as though the phone icon and the volume icons are getting pressed resulting in the volume controls and the phone/flight mode popup appearing on screen.
I guess it is all down to dirty connections.
Do you have a link to the thread about dismantling the hinge, I can't seem to find it.
Thanks.

re isopropal alchol
only use 99% alchol to clean contacts anything below that can cause corrosion on printed circut boards and contacts.

any progress yet.
mine stopped working today too.
but when i took off my screen protector, it worked for a while.. now its dead again.

I think the screen protectors may cause this problem, as I too had this problem with a screen protector; but when i took it off it would work and and off. I cleaned the screen up and after a few hours my screen was working again!

being in Australia I go to the beach allot. with my jasjar.
the sand gets stuck in the sides of the screen putting pressure on the screen and disabling any input. just a thought that it could be the same with u.
hope u sort it out, otherwise claim it on warrenty sooner than later.

The problem I have with the screen is that occasionally the touch screen side of things appears to stop working and also the the volume, wifi and phone dialogs keep on appearing as if I am pressing the relevant icons in the top bar.
I'm guessing some dirt has got into it somewhere or there is a loose connection, but am struggling to open up the screen's case to inspect it.

i took off my screen protector and it worked an hour...
got home, prepared to go to the T-mobile store.. then cleaned my screen ( without protector ) with a small cloth and it was working again.. so weird..
lets wait and see what happens ..

It's not really that weird: If some dust, or something equally small gets between the screen and the plastic frame, it can put enough pressure on the screen, and so the touch screen takes it as a constant (or intermitent) input, invalidating any other action on the rest of the screen.
I just received my Aquapac waterproof (and sand/dustproof) to use my Jasjar hapilly in the beach! :lol:

oh so annoying, my volume sliders keep popping up now..., as if some one keeps tapping, cause when not in Land scape mode when i open the "START" menu. it scrolls down, the same input/tap as wher the volume is in Landscape mode
There must be something wrong ... my screen still isnt working properly

one possible solution for touch screen not working
guys.... although I dont need to register onto this portal and it took me 15 minutes to register (fault of my own) but I got so much relieved with the solution that it deserved 15 minutes of my effort ;-) I hope it helps someone...just like it did help me....
I own a P835 Asus mobile and from past 2-3 days was having problems - start menu continuously appearing and my taps not getting recognized. Since yesterday my screen suddenly stopped responding to any taps or scrolls altogether.... buttons were working fine but not the screen..... i spoke to the facilities centre this morning and was about to take it to the shop but due to my laziness...didn;t go.....
Thanks guys.... what you mentioned above is very correct.... it was just a tiny molecule of dust that the screen was interpreting as my input and finally refusing all my taps..... I just cleaned the screen and the speaker side with the mere stylus n things started working.... thanks a lot.... more than laziness was this worry cause I just bought this piece a month before....
so people...before takin it to the shop....try this one too.....huhhh.....

[Q] Screen crack and blackout after phone call

So my sister who also has an Aria dropper her phone and now there is a huge crack on the screen. She doesn't have insurance so she is trying to find an alternative way to fix it.
Simply replacing the screen would work, but another problem started happening when she cracked the screen. During a phone call, the screen will turn off, as it should, but when the call has ended, the screen stays off and the only way to turn it back on is to either pull out the battery and reboot the phone or to plug it into a charger.
Does anyone know how to solve this problem? Will replacing the screen fix the blackout issue? Or is this phone just trashed forever?

sounds like it destroyed the phone and the proximity sensor. i'm not sure if replacing the screen will fix this.

I actually had the exact same problem after dropping my phone during a call. I noticed that I didn't have to pull the battery to end the call if I held it up super-close to a really bright light (desk lamp, etc).
There were many times when I was on the street (in nyc), and had to find a bright light to hold it up to.
I dropped my Aria right on the corner with the ambient light sensor (in the upper right corner), which shattered the glass right in front of it.
Amazingly enough, after a few weeks, it started to get better and better - and now, nearly 4 months later (yea, i just deal with **** lol), it will hang up cals properly.
I'm actually working on replacing the screen right now, btw

[Q] Bug during call, please help!

Hello! I have recently installed CM9-20120319-NIGHTLY-jordan on my Defy and it seems there's a problem during calls. The proximity sensor is not working (when I'm taking the phone from next to my ear, the screen won't turn on, as it used to before in the CM7). Also, the screen remains black and won't turn on unless the other party hangs up the phone. I need some help about how should I fix this. Thank you!

Ok, I know this is really old, but I just had the same problem and want to document how I fixed it cause this is a top search result for me and I figure it must be for others too. I had observed this behavior just after installing Quarx's CM11 Nightly, and I had assumed that it was a software glitch.
Some months ago I actually managed to crack the glass on my phone, and I had ordered replacement parts. I thought I had just ordered glass, but I got a whole new case that was all shiny and new. So I swapped broken parts for new and went on my merry way. But I did notice that the volume down button was sticky, but I just dealt with it for a while. Recently when I was Rooting and installing CM11, I got frustrated with my volume down button trying to get into the recovery system, so I cracked my case open to take a look at the sticky button. I found a small plastic burr left from the molding process. I sliced it off with a razor and reassembled and thought nothing of it. Happy with my functioning volume down button I proceeded along my merry way.
Now, why was this detail in the story important? Because in between Froyo and CM11 I had inadvertently caused my proximity sensor to malfunction, by tightening the screws too tight when I put it back together. It wasn't CM11; it was me. The fix was easy. Pop off the battery cover and loosen one screw a half a turn at a time until the proximity sensor started working. Pro Tip: Dial into voice mail while trying this so you can have an active call without hassling your brother.
I only know this now because I found this video:

Screen becomes unresponsive to touch frequently

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 !

Please help! How can I keep screen on during call?

So I broke the screen. replaced it and it worked fine. However i noticed the adhesive wasnt holding it tight enough. so after a few days I pulled the glass up as munch as I could and used some superglue on the top and then clamped down to hold in place. Now no more light is coming through but.. When I make a call as soon as a i press dial the screen turns back regardless of my distance to prox sensor. I'm assuming I got glue on it or broke it.
Eventually I will replace LCD but in the meantime is there any way to simply have the screen stay on during callsly ap?
I tried a few apps which did nothing. I looked for settings but nothing jumped out at me. I swear I have done this before on either an iphone or a much older android device.
Any suggestions would be great appreciated. Right now by using switches under accessibility im able to hang up at last but I cant turn on speaker and not sure how to set that up. So if there isnt a way to keep the display on any suggestions on how to set up so I can hang up and turn on speaker phone in the most effiecient way?
Its gotta be built in the system to keep the display on during calls but maybe not.
Again thanks!

There used to be an Xposed module to disable the proximity sensor on some SoC... But it is VERY SoC dependent from what I understand... And it may not be supported anymore...
Your other alternative would be to disable the proximity sensor in the kernel... I know it CAN be done... But I have no idea how
