Touch screen issues? - G4 Q&A, Help & Troubleshooting

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.

Touch screen problem

Weird this. I sometimes find that the 'dock' area of the screen will not respond to new touches. Therefore I can't open the phone or the app drawer etc. Odd thing is that I can drag icons from elsewhere over the area which makes me think this is more a software issue than a hardware one. If I open Chrome links can't be opened if they are in the affected area. It's just weird.
Some times this requires a reboot to clear but other times it appears to clear by itself. From my observations it seems to start after using the camera app.
Any ideas? Could this still be down to a defective device?
Matt.
I experienced the exact same thing. Everything else works normal though. It happens after using the Camera app and goes away after I clear the app from the multitasking window (which I have to do app by app since also "Clear all" can't be tapped). I just hope its a software bug that can be fixed by an update.
Clearing running apps doesn't sort the problem on mine. Your problem certainly sounds very similar though especially given the connection with the camera app in your case as well. Tried a factory reset and the problem persists but it is very random and difficult to reproduce. Still not 100% sure it's not some sort of hardware fault as I can't really see any touch screen related problems being reported on the web and this one is very irritating.
I experienced this once - also after having the camera. I rebooted and haven't experienced it again.
I have the same problem where my touch screen doesnt respond in the corners sometimes. Really abnoxious when playing games and then i just lose because of this. I send my phone to HTC and i waited 20 days to get my phone back with the same problem as before. First i downloaded a touch screen test app, and there it didnt show any response in the corners but another touch screen test app registered every touch.
I have the same problem. Seems to be caused by either the camera or the photos app. Closing them doesn't help here, but a reboot does. It's something that started happening recently so I hope an update of some sort will fix this.
Very annoying... If anyone has found a permanent solution I hope they'll share it here.

Yes it is a software issue. U just need to revert the photos app back to the factory version. This can be done by going into settings >apps >photos app and the click on uninstall updates. Then reboot your device and the problem should be gone. Try it out and tell us if it works for u as well.

or you could turn off the screen using power button and then turn your screen back on using fingerprint option....
its something to do with incompatible apps messing up frameworkres

Touchscreen scrolling and swiping problems?

Is anyone else having issues with what appears to be dead areas when scrolling, swipe texting or otherwise using your phone? In typing this message the phone just lost my finger on 4 occasions. When scrolling webpages it often just stops and clicks an area where my finger was. I'll get occasional double clicking on things when I do try to click. I have trouble purposely replicating my problems but in regular us it is driving me nuts. Because I can't constantly replicate I'm not sure trying to take the phone back will be successful. Anyone else having issues? Could there be something I'm missing somewhere?
Sounds kind of mean but I hope your issue is isolated. I saw the ifixit teardown and the ease with how the digitizer came off of the glass has me worried about the longevity of the digitizer.
Happening to me insanely often on my regular Pixel.
This happens to me occasionally. Sometimes, when typing it spams v and b. If I find anything I will fill you in.
Yes, I'm having this problem with my Pixel. It happens across all apps, even in Settings. Generally it happens if I start scrolling after not touching the screen for a little while.. for example when reading a news article. The scrolling freezes, and I can move my finger around on the screen and it doesn't react, but then it might pick up my finger again and the screen jumps around or clicks on something even though I've not lifted my finger from the screen. I tested it in safe mode and it happens there also. I even got my original device exchanged, and the same thing happened immediately on the new phone. I've been in touch with Google Help this morning and they've confirmed it's a software issue. They've asked me to submit a bug report. It'll help them if more people report the bug though and they have more data to fix it, so if you're experiencing the same issue, please report it! You can chat directly to Google support through settings on your Pixel.
Haven't had any issues but I know the google keyboard can be a bit glitchy at times. I used to have a nexus 6P and I would get weird issues with that keyboard as well on that phone. Getting them less on my Pixel though.
Having issues with typing on my 6P, it's so odd as sometimes I can not type when in desktop mode and sometimes not when in mobile. Switching the webpage screen mode and also doing a soft shut off on the phone and coming back both fix it temporarily. Thought at first using a different keyboard app might help but what app it runs does not solve the problem.
Same problem here. Google pixel
Happening to me as well. Did a factory image flash and it seems to have helped but still happens once in a while. I notice it the most when I'm using reddit sync. Seems to just happen too frequently.
Just an update on this... After doing a few steps suggested by google tech support like, test on safe mode, factory reset using bootloader method, etc... They just replaced my unit. I'm using a new one today and problem is not existent now. I would assume the problem would be hardware.
To be honest, I'm quite happy with their tech support...24/7 support and the staff are really competent. This in my opinion, is worth the high price of the pixel. Good job google!
I have the standard Pixel, and I too had issues with typing (occasionally wrong letters or spaces would register), and dead areas in the top corners of my screen when trying to open apps. I was going to return it one day after confirming that the dead areas at the top of the screen were persistent, but for some reason I decided to grab an App from the bottom of the screen and move it by sliding to the top area. Instantly this cured the dead area issue, even after I moved the app back to the bottom of the screen. It's as if it recalibrated the touch sensitivity vertically as it stopped erroneous spaces when typing too.
Pixel 2 one handed thumb scrolling issue
I have the pixel 2 and I have intermittent scrolling issues when I hold it one handed and try to scroll with my thumb. I realized it's because the base of my thumb is brushing the opposite side of the screen and preventing it from scrolling freely.

You should probably post about that in the Pixel 2 forums.

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

Did you remove the factory installed screen protector? Maybe it's the cause of the issue
Return that pal, that doesn't sound good at all.

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.

Question Keyboard delay

Have any of you experienced a lag in the keyboard popping up in some situations. I'm using gboard on the latest update and it's so annoying I have to wait for the keyboard to come up
Seems like there's so many issues with this phone out of the gate!

I have to admit i've not come across any problems personally, although I am waiting on my Google Fi SIM (which should be arriving today) so that may change things.
My op9 pro arriving today
I too have the delay with the keyboard
are you all using the standard keyboard as I use SwiftKey and don't appear to get any issues

No major issues for me thankfully. Only minor ones I've experienced is that the "1" and "0" keys on the keyboard have a small delay before they appear. I'm guessing edge detection is a little aggressive to make sure I wanted to tap those keys?
And taking video sometimes has this weird wobble effect in the video with occasional brightness flickering on walls for instance.
Other than this, everything is great. It will be fixed in software updates. I still haven't downloaded the latest one which said it improved video so maybe this is already solved.
I have not had any problems. Not sure if matters but I always set the phone from scratch, no copy apps or backups. The most I do is export settings and import setting for some apps.
For me, it has proven to avoid a lot of "weird" things...
Not sure if this is the same issue OP is having but I've noticed since day 1 that there is a noticeable delay when pressing or long pressing the keys on the edge of the keyboard. For example, there's about a split second to full second delay when pressing the backspace key. So that means, I have to wait for that delay and then wait again for the original delay if I want to delete whole words at once. It is super frustrating.
I did some testing to see if maybe it's because I'm using gestures and the delay may be caused by the phone detecting the edge touch and waiting for a swipe inward to go back, but that's not the case as it happens with the button navigations too.
Looks like my issue is known and has been around for a while, even though it was not present in my OP7 Pro as of last week when I switch to the 9 Pro.

I've been using SwiftKey and haven't had any issues at all. It's the opposite actually, typing feels very fast and smooth, keyboard always appears instantly and the haptics when typing are very satisfying. Hope it gets fixed for you guys.

Glad to know it doesn't seem to be a universal thing, thanks for letting us know. I'm hesitant to restore to factory settings due to the time it'll take to get everything set up again, but I may have to bite the bullet soon.

I've never once encountered the problem you're referring to.
I Use gboard beta (this is better anyway because it has all the cutting edge sh1t), and turn off all system animations.
Problem fixed. You're welcome.

Sadly I can't update just yet as the install fails, likely due to me flashing the EU boot image on my global variant. When I update I hope my issue is fixed. I also just realized that my issue is a tad bit different than OP's. I decided to make a short video for you all to see, link at the bottom.
I started typing in the center of the keyboard so you can see how quick and responsive it is. Then I go to the edges and you'll see there's like a full second delay until the phone picks up the touch for the key. For the scrolling, I tested along the entire edge and it was the same which leads me to believe my issue is not a keyboard typing issue, but a full screen edge touch delay detection issue. You'll see that when I start the scrolling in the center of the screen, it's quick and smooth. When starting the scroll from the edge of the screen, it initially jumps before scrolling smoothly.
I swear it almost feels like the phone detects the touch on the edge but does not register it right away and instead waits a second to see if I will then slide in from the edge to go back since I'm using gestures. But I tried using the button navigation instead of gesture and the delay is still there so idk at this point. I can confirm that this issue never happened on the OP7 Pro that I'm coming from.

Same here. The 1 and 0 keys have a delay. I assume this has to do with edge touch rejection and it's be nice to have some settings to change this behavior, like Samsung has done (if that is the issue). Could be gestures as well with the OS wondering if you'll do a gesture, but it should not be this much of a delay. It is annoying for sure.

I'm pretty sure it's due to the gestures. I just tested it on my regular 9, same problem, it takes a fraction of a second to realize I'm scrolling and not trying to do a gesture if I'm at the edge of the screen. Does it happen with button navigation?
