[Q] Touch screen malfunctioning? - G3 Q&A, Help & Troubleshooting

Hello guys,
My G3's touch screen has been acting up for a week now and I am seeking help to pin point if it is a hardware issue or a software issue that can be fixed.
Whilst typing (have used different keyboards) I cannot seem to press the letter 'k' and the letter 'r' or any keys directly above or below those keys. I wondered what the problem was and started swiping my screen to see if I can flow through the UI of the phone smoothly. Suffice to say that it didn't which then prompted me to turn on the "Show touch" & "Show touch data" within the developer settings of the phone.
After turning on those two options, I could clearly see that the screen does not recognise any input on two parts of the screen. This can be seen in the screenshots I have posted.. As it shows when swiping on the screen it skips an entire column of the screen on both left and right sides of the screen .
I was hoping someone could shed some light in this issue since I have been trying to troubleshoot this problem with no avail for the past week. If this is hardware related then what would be the best course of action?
Additional Info:
* Have tried different firmware and roms
* Have tried other keyboards like google keyboard and swiftkey
* Have tried to clear cache and factory reset
* Have taken it to phone repair store and they said they would have to replace the LCD.. Thought I'd post here before I go that route.
Any help would be greatly appreciated.

You're gonna have to replace the digitizer. Unfortunately I had the same issue with my nexus 4. That's why I have the g3 now.

Thank you for your reply.
Was hoping I would not have to go through that route but it seems inevitable .
Is the G3's digitizer and LCD stuck together? If so it'll be a costly replacement :crying:

That I do not know. I know the frustration though. It might be a big charge

[Q] Mytouch 3g Slide Screen Issues ? (WARNING : EXTREMELY LARGE PHOTOS)

So recently my mytouch has been getting worse and worse. I'm not exactly sure if it's me or if it's the stupid phone because it's been degrading over time for some strange reason. First of all, the camera is **** for some reason, this is my second replacement phone from T-Mobile and it's extremely blurry for some reason(apparently it's a common problem but not common enough apparently for the tmobile representatives I've met with have seen before). Secondly, it's been becoming unresponsive at times although i kill my apps after i'm done with them(I probably only have internet, and facebook running most of the time). Third, ever since I've factory reset it, it's become very glitchy for some reason. One of the problems is that I would close the physical keyboard but after sending a text and all of a sudden the screen goes black and the only thing to fix it is to hit the power button and press it again to get it off of sleep. Another problem is after i send a text i close the keyboard and the screen repeats but the location of buttons is still where they're suppose to be on the screen.

As you can see the buttons are on as the phone is on but the screen is black and unresponsive, i realize i can still go to apps while like that somehow but to fix it i just hit the power button which shouldn't be happening though
Fourth(Repeat Screen)

As said before unless you didn't read this happens after i send a message and close the physical keyboard...
And thank you for any suggestions you guys have, help is appreciated, also for taking the time to read the thread
Jezussss!!!!
Dude.. you dont need pictures, and if you post them.. resize them first.
Make the thread want to be readable, like-able. Ask yourself, would you read this thread?? and with yellow highlights that no one can even see????????
You also need to post if you're phone is stock, what rom you are on, what version..

This is a hardware problem (the repeating screen) that seems to be happening to many people. (it happened to me before which is why i replaced my previous slide). After my 2yr contract is done, im gonna stop getting phones with keyboards because this also happened to my previous htc slider phones

So it's actually because of the sliding part of the phone ?
I'm not surprised, this phone was pretty cheaply made imo, literally a piece of crap :\
I guess I'm getting the new iphone once it comes out and my 2yr contract is done

Oh I see, well I tried to get it replaced but HTC was a bit suspicious when they wanted my credit card before anything ......
I have the same issue with my phone
As I was looking at your photos I realized I have the same issue going on with my phone. Does anyone have suggestions on ways to fix it? Personally, I do not believe it is a hardware issue. I do believe it is more of a software issue. That update that HTC offered is definitely screwed up! Ever sine I updated my phone, all of these problems started. This problem did not occur beforehand! My phone was working fine - before this "software update."
Same Problem
I had the same exact problem with the Repeating Screen (and completely agreed about the camera lol). Yesterday I tried demonstrating to my friend the problem, and permanently blacked out my screen. Now, the phone works in the sense that it receives calls, the home keys light up, and the camera still takes pictures. However, with no screen to select any options or perform any functions, the phone has been rendered completely useless. I, too, would like to figure out what the problem is and if there is any possible fix.
Sorry I couldn't be of much help. Just know you're not the only one lol
My girlfriend had the repeating screen issue back in May/June of this year. It was more than likely a software issue, because it became incrementally worse as the phone opened and closed until it came to a point where absolutely nothing could be done when the phone was moved horizontally.
I had T-mobile replace the phone at the time. Unfortuntely an idiot I work with who was supposed to mail it back didn't, I got stuck with an extra $360 on the bill.
Worked out paying for the phone with them yesterday morning, this morning my girlfriend messages me to let me know the screen is acting up again.
Potential Fix?

I would recommend replacing your flex ribbon. It worked for me, and from other threads I've read, I believe it's the cause of these issues. It's a pretty easy fix ( coming from me, who's far better at breaking electronics than fixing them, lol ).
Here's the flex ribbon that I bought off of Ebay ( it's the cheapest I found and it comes with the tools too ):
http://www.ebay.com/itm/170647168235?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
And here's a good video on disassembling your Espresso:
http://www.youtube.com/watch?v=-jgFHuVWlig
P.S.: I'd recommend being more delicate than he was with the volume ribbon though, as mine seemed very frail. Also, this video is for replacing the digitizer, so you only need to follow it to get to the flex ribbon.
A month ago, I had issues very similar to the ones you posted. Sliding my keyboard out ( in any way but gently ) would occasionally split the screen or freeze the phone. Even without using my keyboard, the phone would occasionally freeze while "settling" after the boot animation, and sometimes even during the boot animation. Slowly, those "occasionally"s become more and more frequent, until my screen just went black one day. The phone still seemed to work ( lit up when turned on, made sounds, etc. ), just the screen seemed dead. Figured that I was having a combination of software issues ( the random freezes ), and hardware issues ( split & black screen ), but replacing my flex ribbon suprisingly fixed everything.
This is what worked on my MyTouch 3G Slide
i just keep sliding the phone. and turn off the screen then turn it back on. but not turning off the phone.

Touch screen issues?

Hi,
I have a UK sim free model. It sometimes misinterprets a tap or adds a phantom tap. Its not terrible but I'm sure mine has a issue. A quick Google and a tweet tell me I am not alone. Anyone else seeing this? I could return but I'm dubious it's hardware related...just not sure if it's worth waiting for a software update...

I have same issues with my g4 here in the US.
Unfortunately same here, on a G4, korean model F500S.
I have the same issues on my G4. So probably returning it won't solve it. I notice it the most when I am scrolling in Facebook or web pages I will open a link accidently.
I have the same, occasionally it just won't respond to some taps, i find just pressing the standby on/off button quickly sorts it but it is very annoying.
same here in israel, sometimes do not respond to double tap on lock screen to wake the G4 up
im sure its a software issue, prolly the LP 5.1
Are so you guys using screen protectors? That was the issue for me with g3 and g2.

I am using the out-of-the-box protector on G4. So the thing u mentioned was it with this kinda protector or after-market glass protector?
Try...SGS Touchscreen Booster - Google Play Store
I have run into this same problem with my Verizon G4 (VS986). Many of my taps have gone unrecognized.
I did find this.... http://forum.xda-developers.com/g4/help/fix-touch-screen-registering-touches-t3128518
I tested the software that was recommended...and IT WORKED!
Give it a try...can't hurt!

Okay, I was able to replicate my bug. It happens after playing a game and stops after some time. Turning autorotate back on and switching back and forth from landscape view fixed it.
Hey guys.
I was searching the forums for a fix that solves the phantom/ghost touches I'm getting frequently on my LG G4, H815 model.
Sorry for the long post but my case looks a little more complex than the ones I've been seen in here.
In my case, that's how it happens:
I receive several multi-touches at the same time, usually when Data is enabled. Sometimes it starts right when I switch from Wi-Fi.
It happens often when I'm driving and using Location+Data as well, which drives me crazy. I does also happens (like another user mentioned in this thread) when scrolling down a feed (such as on Facebook) and it suddenly likes/shares a photo/post. It also drives me crazy! And there is also the case where it taps the keyboard and send crazy typos on chat apps when you are real-time texting someone! Another hassle is right after using the camera and opening the gallery to show someone the taken photo...it suddenly scrolls the gallery and open another photo. I just can't make it to see the taken pic. Therefore, I really wanna fix this so bad since it happens every time I need something right away.
A workaround that's been helping, though it's a pain:
I found that pressing the On/Off button and giving it a few seconds will return it to a normal state. The problem is when it happens while I'm driving and are supposed to take an exit/make a turn at the moment. There are some other cases where I'm into something and giving this few seconds is not an option.
Trying right now:
Someone suggested in this thread to use the SGS Touchscreen Booster. I'm giving it a try right now.
Important notes:
This issue has been happening since I got this phone on November, 2015. We got this 6.0 update recently and I was hoping that it would fix it. It didn't.
I have an after market screen protector that I applied in order to see if the issue would go away. It also didn't.
I have been searching about a digitizer replacement but I don't think is a hardware issue, since it just doesn't happens when I'm only on Wifi at home with Data disabled. I believe that the problem is the Data connection that triggers smth.
Any thoughts?
Does anyone have any idea or have experienced the same scenario before? Any thoughts on my guess of data enabling triggering the ghost touches?
Sorry for the long post and thank you so much for reading it.
I think it's both, its hardware and software, LG tried to fixed it but it makes it worst. You can solve the problem for few seconds putting your five fingers at the home menu, It goes crazy and after it stopped making ****. Anyway this phone is great but all the problems make it ****.
I am going to use this thread even though I think my problem is not as serious as yours are.
My problem is that touches are registered, but no action is taken.
For example. Quickly tapping on an icon on the home screen will highlight it, but it will not open the application. I enabled the option in Developer mode to display the touches and the touch is registered. It's just that the app will not load. If I click for a tad longer - it loads. Happens on both stock Launcher and Action Launcher. I have not noticed it happening outside the launcher.
I read something about a keyboard update, but in the Update Center I don't have anything related to the keyboard.
The icons I see it happening with are located in the lower part of the screen.
I am almost sure that this is a software problem, but several updates have not fixed it. Currently on v20d.
Any suggestions or ideas?
After a few more testing and monitoring, I found out that the ghost touches only take place when I'm on LTE.
And even more weird, while driving through some specific areas when I'm commuting.
It's just so weird to think that some towers may send a LTE signal that may cause the ghost touches.
At home, at work, wifi or data, it doesn't happen.

Multitouch problem, screen is possessed

Hi guys I have a problem with the touch response on my G4 (H815)
Basically when I use multi touch (and sometimes just normal scrolling) in certain apps the phone will recognize screen taps at the bottom of the screen at the home and back buttons and sometimes other areas, I have used the 'multi touch app' from the play store to confirm that this is indeed the case. This is extremely annoying as apps exit by themselves because of this. It doesn't happen every single time either, just sometimes but often enough for it to be annoying and so may be hard to prove to my carrier or LG if i send it back cause they may say there's nothing wrong with it.
It seems like a hardware issue and in that case the phone should still be under warranty right? I got it in August and haven't rooted or done anything invasive.
There are many people having issues with the G4 touchscreen. Check with your carrier and see if you can exchange it or what your options are.
Hi,
Same problem for me, the back and home button seems possessed. Se this video dropbox.com/s/540ozmvdnhemv8f/MOV_0005.mp4?dl=0 for an example. I bought the phone Thursday last week and it have been this pretty much since unboxing. After a factory reset the phone acts normal for a couple of minutes or hours, but goes back to that stage were I can't use the phone at all. I've managed to update to the latest software but the problem didn't go away. I'll try to contact the supplier I bought the phone from and exchange it tomorrow.
Since I do not have enough posts to post external links you have to figure out for youself what to type infront of the "link" I included.

Ghost touches in upper third of screen

Hi.
My Z1C seems to have a similar case of faulty display as described in some other threads here, but actually a bit different. The phone is stock, not rooted, running 5.1.1
Whenever I do something, there are ghost touches in the upper quarter or third of the screen. They only happen when I am not touching the screen myself. It happens no matter what I do. When I browse internet, it clicks links, when I scroll contacts, it calls people, when I am on facebook it gives likes etc... It seems like the more demanding task the phone is performing, the more ghost touches.
I turned on the developer settings and the "show pointer location" option, which leaves track of the last touch on screen, so I can research the issue.
I found out that when the phone is on home screen, it happens very rarely or not at all - the track of my last touch stays until screen turns off.
When I jump into the touchscreen service test, it does not happen at all. I can draw a line around the whole screen and it stays higlighted indefinitely.
In lock screen, it also doesn't happen.
I tried it in Sketch and it confirmed what I thought, when I was just sketching, from time to time a dot appeared in the upper part of the screen, but when the phone was downloading or installing in the background, the screen literally had seizures. I touched and released and then a storm of dots started to appear around the top part of the screen. It stopped after 5+ seconds, and after another input from me, the screen got another fit, drawing more dots.
I don't have any experience, but I think that since the problem doesn't happen constantly and it doesn't even happen at all in test mode, it could be a SW mistake.
I have found this thread https://forum.xda-developers.com/showthread.php?t=2691849 and I'm willing to try, but 1) my phone is still under warranty and 2) I have never done a root so I am not too eager. Do you think I should try that? Or has anyone found another solution for this problem?
Thanks.

As You have warranty, I would strongly suggest that You go for a repair. I had the same issue in beginning, ghost touches appearing randomly, going away only after reboot. I was rooted and xposed, so went full stock without restoring any apps or data from internal storage, yet the problem remained, thus ruling out the point that it was software problem. And then after a week or so, that much part of screen stopped responding to touch entirely. You can see details over here, Another user had same problem as Mine and had the same end result,
OK then, I'll go for a repair. Thanks for the tip.

I am having exactly the same behaviour as you described .
Ghost touches happening on the upper part, and triggered when a demanding task is running.
Actually I didn't realized completely about this, I thought it was just random, but right now after I saw your post, I tried an app similar to Sketch while upgrading apps or playing a video in the background. And dots in the upper part start appearing crazily.
Did the phone repair solve your problem ? Mine is not in warranty, so I'll have to pay for it.
But also in my case, before this thing happened, I got some water damage and that upper quarter of the screen stopped responding.
After replacing screen+digitizer I got this very specific behaviour you described.

In my case, I realized that I bought (probably) a badly re-fitted phone. Display's backlight was visible around screen panel edges, where I'd say it shouldn't be visible at all. I decided to return the phone and got a refund.
Sorry for not being able to help you.

Ok. The aftermarket screen I got has that issue with the screen edges also. Very probable you are right.
In my case I water damaged myself. It seems that after 2 years of intensive use, waterproofing is gone, by accumulation of slight hits or so, never had a single crack on the screen. I read many posts reporting this happening, even with much less use time.
Too bad, I loved the phone, but I'm afraid that sending it to repair will mean to change the PCB or similar for a complete fix, which can come to a ridiculous price.
Seems it will be time to move on...
Yeah. If you want it fixed properly, you'd need to send it to Sony, and for the money it would cost you, you can probably gen a new phone. Sadly, similar phones aren't made anymore.

screen stutter, complete loss of touch.

Been using the phone for the last 12 hours and I noticed something towards the end of my use last night.
The screen seemed to become unresponsive. And when it would work it would start to make its own input when scrolling and opening any app or link my finger would drag over while scrolling.
Changed refresh rates, changed resolutions, even seen if the blue light filter was the issue. Nothing.
Almost seems like the screen drops frames when scrolling, like it gets caught on something.
New development. Fingerprint sensor doesn't respond at all and inputting a pattern is damn near impossible. Going to try removing the screen protector to see if that could also be the issue
Did a factory reset
Issue seems to be where the finger print scanner is
It's almost like a dead or unresponsive zone.
Sounds like a factory defect, better have it replaced if resetting didn't worked.
Small video showing when scrolling over the fingerprint reader, the screen almost loses input
Defect.
Samsung has been little help lol. They want me to send it in for repair instead of an exchange. They also said to just order a whole new one and return the one I have now except the black 128 is sold out

one of the first things i did to trouble shoot. still having the issue. sometimes the screen completely loses all touch registration and it doesnt even know im trying to swipe or push on things. just realized it did this also after tmobiles new software update.
im still waiting here to hear back from samsung on how they are going to fix this issue
The same thing happens to me. Pulling down the notification shade seems to be the only thing that still works. It seems to goose the phone and it starts working again.
Test using the *#0*# diagnostic menu and use the Touch test.
