[Q] Touch sensitivity issue cause?

I've been reading through the previous threads and I'm still confused if the issue is hardware or software related. I have the AUO panel and have broken swipes, and times where I can't scroll properly. This has been going on a couple months now and it's getting on my last nerve since it's frequently happening when I need my phone to work properly. All this time I assumed it was software but a couple threads mentioned it was hardware. Trouble is, some people with the JDI screen also have issues so I don't understand. My question is, has anyone ruled out software by flashing an AOSP rom? I'd rather not send this to Sony if at all possible since they don't cross ship and I'd be without a phone.

I have rarely an issue with the touch screen, when swipe up or down, it doesn't swipe it acts like I've just touched (clicked) once the display. I think it is a software issue, because in my case, if I turn off the display wait for 2-3 seconds and turn it on, it works with no problems.
Can you point me please to other threads that have this issue in discuss?
Thank you!

Have you removed the asf from the screen and placed an actual screen protector on it? I found that this really helped with the weird screen issues.

I have a screen protector over the ASF. But that has nothing to do with my issue, because, like I said, when I turn the display off, wait 3 seconds, and on again everything is working normally.

Yeah, I reboot usually and the issue temporarily goes away. Then it will come back a day or two later. I'm afraid to remove the ASF because I've read some issues with goes touches even with a screen protector. I just want the issue to be fixed... I was thinking of flashing a AOSP rom but wanted to see if anyone with that ROM had any trouble or not. Maybe the L update in January will fix things.
Here are the resources I've read on this issue:

I have rarely that issue, like I said I just turn off the screen, and after 2-3 seconds turn it on and it's gone. I'm sure this is a software related issue.

If it helps at all, I never had the issue in the two weeks I tried an aosp rom. However the camera and battery life were a bit lacking so I'm back on a stock rom.

I haven't have the issue too in the past weeks, I've wiping cache and dalvik cache pretty often , because I've installed some system apps. Anyway I will really want to know the cause of this
L.E. I'm still on stock firmware.
L.E. 2 : The Glove mode function, in the Settings-Display menu has an application or something? Has a file redirected to it? Is there in the phone's system a file than can be edited or deleted or something for the glove mode function? Maybe we will find answers there.
I'm not sure that I've made myself understood with the question.

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.

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 won't wake up sometimes

Hi,
My phone sometimes doesn't respond when I try to wake up the screen. Double tap, power button, fingerprint, nothing works. The only thing I can do at that point is to force reboot. This is a pretty serious issue. When this happens I had to wait for it to reboot.
Anyone else having this issue?

I'm also experiencing this and I'm not able to reproduce it. It drives me crazy, I so wanted to like this phone

That has happened to me too. Probably 3 - 4x over the course of a little over two months of use.
HMD Global's software sucks. This will be my last "Nokia".

Their hardware is pretty good. Only if the bootloader can be easily unlocked... this would be a good phone.

I think I may have experienced what you're talking about. Most of the time for me, it seems to be a notification screen overlay issue. When it happens, I get no reaction on my screen until I brush from the top down, as if I'm pulling down the notification screen. After that, the phone rights itself and behaves normally.

I've experienced this in the past and recently. Not often, but sometimes. It seems to be camera-related.

Question Gboard intermittent freeze

Does anyone else have this issue where you are swiping and it will suddenly freeze and you have to wait for it to unfreeze, maybe Gboard needs updating for Android 12

Not specifically Gboard, but quite literally only just today I've been getting some little lags on my Pixel 6 Pro and experience the same freeze on SwiftKey.
Running Kirisakura and all has been well with no new apps installed recently, but indeed today been getting some weird brief lags....
Unsure what the cause could be, but thought I'd share my experience nonetheless

I had a ton of Android 12 issues that were tangentially related to Gboard: minimize arrow persisting even when the keyboard wasn't visible, mysterious System UI ANRs after using the keyboard, etc. At some point I had opted in to the Gboard beta and opting out to the production release build fixed all of my issues.

Yes. Sporadically

I've been having intermittent issues with both Gboard and Swiftkey. There's been a few times when the keyboard doesn't display when I'm trying to message or send an email. I have to restart the phone. A bit of a pain in the butt. BTW, I have not received the December update.

Trying the beta version now to see if that fixes it

I do also encounter some lag when typing. Already contacted google support about it. You can either wipe your phone, if the problem isn't gone you are able to send it in for warranty.
I assume it is a software problem, so I won't do anything for now.
But glad to see there are more people who have the same problem.

As you worked out seems pointless wiping the phone when its most likely a software issue, the Gboard beta is so far ok for me

I've switched from beta to stable
I do also encounter lagging when browsing in chrome or switching between recent apps. Not a huge deal breaker, but it should be fixed

Maybe this is the cause

Oh I'm glad this is being recognised! As whilst I don't use Gboard (SwiftKey instead) I have the lags, which aren't just typing but also when scrolling and so this lag explanation of occurring when the battery percent drops makes sense as it is very much intermittent.
Will hope to see a fix soon.

This is getting worse for me, was out typing before when it just locked and then after a few seconds a load of gibberish came out

I wonder if this is the cause of some entire screen lock-ups for some of us until we turn the screen off and back on?

Damn, that's pretty bad and I haven't experienced a lock-up of that level. Have you experienced the lesser lock-ups as well? The one that I described in addition to your five minute lock-up?

If it is the Accessibility Services issue plaguing others, it's pretty crazy how extreme the issue is for some. Vs the small delays/hithces that I've read, the majority are suffering. Hopefully Google fixes this soon as I don't want to play device lottery with a refurb.

The only real Accessibility setting I used was dark mode either way this has been going on since October so I'm going to try this new patch from (Jan) Google but if it hasn't fixed it I'm gone and will never buy a Google device again, I found not being able to swipe text etc without freezing for all this time is just pushed me to far now

I just had it happen once on a fresh install of the Jan build when I was scrolling through Discord. Haven't updated the apps yet so that could of been why. I also ran the Pixel repair tool and I'll see if it happens again. It is pretty annoying when it happens and having to stop what you're doing to turn the screen off and on again. Don't really want to deal with Google during a time where their support is non-existent and end up getting a scratched up, dinged up refurb replacement. That or get a replacement and the same crap happens.
