The delayed responsive to swipes is one of the touch problem feature.

If only someone that got the Verizon/Korean update that supposed to address this issue will clearly state if the problem is gone or not.
[G4 General] marcinek321:
Ok Thanks for reply... Its bad year to buy highend smartphone... LG is so close to be the best but this "responce lag" is annoying ;/
[G4 General] jaggrey:
I've been wondering that also. That update looked like it would address most of the phone's issues.
[G4 General] vegetaleb:
Tried a G4 at Lg showroom today, the double tap to wake was perfect (even better than on my M9) and I didn't notice any touchscreen problem, though it was only for 5mn
[G4 General] AegisValour:
Certainly makes me feel hopeful that this will fix my phone.

However, given the variation of missed taps among people, I would say that people will still have touch issues and LG will either need to provide more updates or repair/replace though ones.
[G4 General] ForbEx:
Absolutely not.

My g4 screen seems alright, it doesn't miss any touch, what happens its just random clicks when i swipe a page, which is rather annoying

ps. i think i fixed it with screen booster app, setting the sensitivity to 100
[G4 General] flamadiddle:
Just got my G4 yesterday. I'm noticing missed taps and swipes on it, but it's not very often. It seems like a simple sensitivity issue, which should be easily fixable by software. Awaiting a fix hopefully.
[G4 General] Snakecharmed:
You know the app says that lower numbers mean higher sensitivity, right?
[G4 General] Quater:
I also have the touch problems

The problem is even worth when I drive the car and the phone in the holder the phone does not recognize the pinch and swipes, but if put the second hand on the back of the phone all problems gone.

I think when hold the phone I experience much less problems.

Would like to know if LG will replace the affected device or not?
[G4 General] kaiowas82:
yes, that's why I've increased it to the max, to not get accidental taps when swiping...
[G4 General] G4rcU:
I also got myself one (international version) and I do, too experience touch issues.

touching and swiping seems to be ok, but button presses very often are not registering.

I did a touch screen test via the service menu that LiamR pointed and all touches and swipes registered fine, but I had to press the "back" button maybe 10 times.

I am seriously considering returning it. This is not what I'd expect from device of this class... :confused:
[G4 General] aygul12345:
Is this bug already fixed?

No for the European version.
[G4 General] Velcorn:
I have no touchscreen issues in general but the knock-knock feature doesn't work too well... Sometimes I have to try 3+ times to get my screen to wake up :/

However, when using knock code this problem doesn't appear and it seems to work almost every time which seems odd to me.
[G4 General] Orsocamillo:
Same problem here (italy) , my phone 815 has a 10b fw version (vodafone branded).

I need to try tapping at least 3-4 times before realizing it has to wake up :rolleyes:

I also tried to enter the hidden menu and test the display with the result that i changed my display into measles :D red dots everywhere, but same problem:

on 2-3 taps just 1 or 2 where drawing dots. That's really annoying, it begins to make me feel unconfortably with this phone :(
[G4 General] flamadiddle:
An update on my experience: I'm noticing far less missed taps and swipes, and I think know why (in my case at least).

When I first got the phone, I was positioning my palm around the lower corner when holding it with one hand, and I wasn't careful about keeping it away from the screen. When my palm was close to the screen was when I noticed the most missed taps/swipes. Since then, I've unconsciously adjusted how I hold the phone to make sure nothing but my fingers is close to the screen. I've had maybe one missed tap in the past two days.

I don't know if that will help anyone else, but thought I'd mention it.
[G4 General] miyuru4u:
I got my international version today ..test for the multi touch and all the 10 fingers registering fine no issues.. i did got 3 hour SOT with this new phone with initial charge... here and their DTW not working like 1 or 2 out of 100 .. i think its not big deal.. i love it
[G4 General] clockcycle:
When testing the phone after full wipe, no customization, for the fist time, I noticed having to tap tap. I then turned off LG Health and removed the default LG weather clock smart widget. No issues on my F500L. I tend to notice it while typing on the keyboard that im not having to tap tap anymore. Even on my nexus6 id mistype often.
[G4 General] Velcorn:
Oh, and another one. I'm using Swiftkey and countless times it doesn't recognize the spacebar... I don't know whether that is a problem due not not being completely used to the software buttons or if it's a different problem since all other buttons seem to work.
[G4 General] chriskwarren:
I have noticed the space bar on SwiftKey is the most problematic as well.
[G4 General] jaggrey:
My phone doesn't bug out all the time but my tmobile replacement definitely does more that the original one I had. Doesn't seem to matter what keyboard I'm using. I've tried stock, Google, Swiftkey, and even Swype.

I guess there was never any word on whether that update from Korea actually fixed things huh?
[G4 General] Azure1203:
I'm wondering the same thing. Restart and it works better. I also forced GPU rendering as discussed earlier and use SGS sensitivity boost.

---------- Post added at 12:56 AM ---------- Previous post was at 12:30 AM ----------

I have this exact same problem. Because it is always the space key, I'm thinking it is a software issues....
[G4 General] Velcorn:
Not necessarily, I think it might just be a general problem with the software keys because when you hit the space between the Swiftkey spacebar and the home button, nothing happens which explains the problem. It is annoying and seems to support my concerns about software keys... I would've preferred normal, "hardware" keys instead :/ I mean there is enough room under the screen to fit those buttons, I don't get why they need to use the display for that^^
[G4 General] Azure1203:
Could be. I've always noticed that if I intentionally slow down my typing, it seems to recognize every tap. Hard to believe it is a hardware issue. This is why the unlocked bootlooder is important. Someone would have a fix already if we could root the damn thing.
[G4 General] got heem:
This problem sucks...Every single test message that I send is jacked up. Ughhhhhhhhhhh
[G4 General] psynonamous:
I've had some issues with my screen skipping, swipes end up multiple taps, drags become a quick swipe and a tap, knocks don't always work. I'm on the G version of the software, and I had the problems on bare screen and with the tempered glass screen protector on it. I went through developer options and turned on some of the touch/data settings trying to see if maybe there was a dead spot or if it would even pick up the skips but so far when I'm running with those on, the screen works great. Just covered with all the lines from the data.

I have noticed that with my case on the skips happen a little less. It's not too annoying for the most part but sometimes when I'm writing a message and it skips a letter and auto corrects to two or three wrong words or in a game it'll annoy me. It seemed like it was worse using the stock LG keyboard, happens less with Swiftkey running but takes a little longer to load the keyboard.
[G4 General] zkyevolved:
I am now on my second device (the first one had nothing wrong with it). I was in my first 30 days, so I exchanged it for the leather back version (which also came with a standard back) and it actually cost me exactly the same price as my standard back one. So this is why I'm on my second one :)

0 issues. In fact, I feel like on my newer one my wifi connection is actually stronger. But that's not something I can test now because I have returned my LG G4 White.

But, this device is French, while the other was German. So, different countries of origin and they're both perfect. I think the majority of the issues are with US models, sadly. Stupid carriers always mucking things up!
[G4 General] AegisValour:
This is literally how mines is. It's actually bearable without a screen protector but it's frustrating when using one.

There was a Korean update that seems to address, but I have no idea when it will reach NA.
[G4 General] Azure1203:
It would of course probably be fixed already if XDA could get an unlocked bootloader with root access.
[G4 General] narcarsiss:
I dont get thsi problem.... Unless i have more than two fingers on the screen at once.
[G4 General] moobieboobie:
I have two of these phones, both on ATT and with the G update. They're both day 1 devices and I thought only my phone had this issue. But the fiance just told me hers wouldn't register touches when trying to take pictures. We both have glass protectors and it seems like touches don't register on the lower half of the phone or if they do, they don't hold when I do a long press. It's almost like pressing rapid fire when I do a long press. It's annoying and this could have been an excellent phone, but the touch issues are making me reconsider.
[G4 General] bicki1:
Have the same issue. After mount in car holder, multi touch is not working. Have same issue at oppo find 7a

https://youtu.be/QvtBUkwpvo4/

Also some scroll that is reading as tap. Very disappointed.
[G4 General] s4lmon:
So I just got an LG G4 and I have no issues so far. I've tested a lot using the Antutu app (see youtube.com/F0gBR611FJE, can't post links as I'm new) and all ten fingers are registering fine. I'm happy with this phone and don't really want to switch to the S6 but is there a likelihood of issues developing? I still have the plastic screen protector on that it comes with.

Essentially I'm asking whether or not a 'working' phone will develop issues or have you guys with issues experienced them from day one?
[G4 General] dadrumgod:
My first one had issues from the first day but I took it back, got another one, and it's been fine. What people don't realize is there's always little issues and bugs with a brand new model of device or software in general, that's just the way it is because it's made by human beings. As far as issues developing that's about impossible to accurately answer because there's so many factors, but mainly it will depend on how you treat it and maintain it overtime. If you don't have any problems at all now you won't have any later most likely as long as its not abused physically or by loading it with dangerous junk software. This phone is way different than any of the others and it takes a little getting used to it just has a different feel than a normal smartphone to me, but I like it. I do still think they could have done a better job but I'm content lol I mainly pissed off about having no root
[G4 General] AegisValour:
Has anyone sent their G4 to LG to be repaired because of this issue?
[G4 General] shook187:
I think most people are waiting on a carrier update to see if it fixes it.

I'm personally waiting to see if T Mobile next OTA update will correct the issue.. If not, I'll look into my options.. Maybe warranty it out or just use my T-MOBILE JUMP and dump it like a redheaded stepchild.
[G4 General] dadrumgod:
I'm unfortunately stuck with mine for the next 5 months before I can upgrade again, but this time I am going to make sure there is no problems and a full solid route even if I have to get a little bit older model of something a little less fancy. I just hate having something I am having to pay so much for basically lockdown with all of the good stuff kept away from me and I have little say so in it. Verizon removing all those features that it did really was pushing it too far. But at least I figured out how to reenable the steam engine for the home screen lol
[G4 General] bicki1:
I did today. Will wait about 3 weeks for respond...
[G4 General] blitz911:
This is pretty much what my screen response is when I scroll using my left thumb..it almost always does it and sometimes clicks on stuff..plus it's not as responsive when I press the shutter button and when texting as well ..hoping an update will fix it..
[G4 General] AegisValour:
I'm Canadian so I don't have the option to just jump and have to bear with it for the next 2 years. We also have not received any updates so, I might decide to wait until at least 1 update.

3 weeks to get it back? Or 3 weeks to get an answer if they'll repair your device? Surely you mean 3 weeks to repair and have it shipped to your door.
[G4 General] bicki1:
I hope to have my phone/new phone back in 3 weeks. Or perhaps 4.
[G4 General] AegisValour:
I guess that seems reasonable. Please do keep us here updated. I'm curious if they'll repair or send you a new one.

Isn't there also a chance that they won't do anything as some of the touch issues aren't easily recreatable without spending time on the device? Ofc yours might be one that it's super obvious something is wrong.
[G4 General] bicki1:
Of course - thay can be THAT stupid. This is very easy to recreate the situation when the multitouch is not responding - i show this today at the store where I bought the phone - I show my car holder, and how the MT is not working. I also have a movie on YT showing this. I will call them after one week to consult this.

I will keep U updated.
[G4 General] Azure1203:
Canadians have 15 days to send it back, don't they? I'm going to try and factory reset mine and see if it helps. Pretty annoyed right now.
[G4 General] AegisValour:
I'm already passed the 15 days. The store was also out of G4's. I had the option to switch to a S6 but decided to take a chance with G4 and LG's ability to handle this problem.
[G4 General] Azure1203:
Ah. Well I just factory reset mine and it seems to be working better. I think I'll keep it for now. I seriously love everything about this phone and have no problem waiting for root. But seriously LG, how can you screw something like this up? :/
[G4 General] superbonto:
whoa. mine wasn't that severe.

and after the v10c update it's 95% gone.
[G4 General] poon:
I have similar issue here when the phone is "isolated".

Moreover, with Tempered Glass protector on, my G4 only detect 1-2 fingers. Without protector attached, my G4 can detect at most 2-3 fingers.
[G4 General] bicki1:
Somebody on polish android forum, posted interestin thing - To try remove plastic cover, and again put phone into the car holder - perhaps the back cover is the problem, but i do not have phone to test this...
[G4 General] chrisokaly:
If anyone is looking for a solution to touch screen issues where scrolls register as taps, go to settings>accessibility>motor & cognition and set Touch Feedback Time to Medium (or Long, your choice)
[G4 General] bicki1:
No, it is nor working at my case :(
[G4 General] Ken4G:
This just increases the delay on long press. I don't like that as a solution (if it is even a solution).
[G4 General] nr2134:
Mine (TMO version) misses quick presses, especially typing and I tried a couple different keyboards. The "knock on" function is completely ignored while hooked up and charging. Its inconsistent when not, but not horrible. Maybe its a grounding thing seeing the charge cable makes this worse. Either way, I cant stand it and may go back to my G3.
[G4 General] chrisokaly:
Well sorry it hasn't worked for you. I've gone 2 days with zero touch errors since changing. Other people have reported a positive effect in my main thread about this.
[G4 General] I Like Soup:
This is becoming more and more of an annoyance. I also have significantly reduced responsiveness when the G4 is plugged in trying to wake the phone up. I did also notice the same issue when the phone is in my car holder vertically, even when it isn't plugged in. While there don't seem to be any issues when I load up the Multipoint app to check it, there are certainly issues when I'm deploying troops in Clash of Clans, selecting troop types, etc. I have to press relatively hard. And this isn't in just one area of the screen, but all over. I am hopeful a further software fix takes care of this. I haven't noticed any improvement worth noting trying the motor and cognition change to lengthen the touch feedback time, but I always appreciate anything that may help!
[G4 General] juju2011:
And it's 15 days or 30 mins talk time or I'd probably have the s6 by now :( no touch issues here but the no root is killing me
[G4 General] gsxcorey:
If I do not have a fix by the time the note 5 or s6+ come out then I done with this phone and lg as a whole. How hard was this to miss in testing? Anyone use the phone for a week? At least do a release about a fix but they put their heads in the sand. Done with lg and wish I would have stuck with Samsung
[G4 General] AegisValour:
Couldn't have said it better. I love this device but this issue real kills the experience and sways me away from every buying a LG device again.

LG claims they're aware of the issue and released a keyboard update to fix it, but that did little to nothing for me (not even using the LG keyboard).
[G4 General] AegisValour:
If I recall correctly, someone tweeted LG and they said that a fix was coming which was apparently the keyboard fix. I don't believe that would actually fixed anything and I think LG has been silent about the issue since.

You can also turn on 'show touches' in developer experiences.

My personal experience with that one is that sometimes it glitches up especially when my swipe registers as a tap. Sometimes tap will register shown through the visual indicator but there is no response from the system, while systems it just clearly misses a tap with no indication.
[G4 General] rousanco:
Found something

Try to put the usb cable without the charger...it works perfectly...i think it's about electricity
[G4 General] got heem:
Very interesting...This fixed my problem...Well, it isn't really practical to walk around with a charger hanging off my phone.
[G4 General] porc1:
Interesting. I did notice an improvement. I'll need to try this out for longer to see if it's a fluke or not... it has started working for periods of time before.
[G4 General] rousanco:
Well...i figured that the problem about grounding..and when you hold the phone touch screen is better than when it on some surface....
[G4 General] vegetaleb:
Do you think it's hardware or software bug?
[G4 General] rousanco:
Its a hardware bug..but maybe i think it can be fixed by software update...not sure
[G4 General] liamR:
It looks like software problem, but my sources in LG say that there isn't a fix coming soon.

I'm returning my G4 (my 3rd) and maybe I'll buy it again when I be sure LG fixed all its problems.
[G4 General] porc1:
I wish I had that option. How do you get rid of a $629 phone that has a known defect, thus effectively making its value pretty close to $0? No one is going to buy it from me unless I lie to them (and I won't). I guess I'm stuck with it and I can go shell out another $175 for a G2... those are terrific. And keep the G4 but disconnected from the network.

---------- Post added at 02:11 PM ---------- Previous post was at 02:07 PM ----------

Well, it isn't making the problem go away for me. It does seem to do it less often though.

I'm still puzzled how this could be a hardware problem. If I use that Multitouch Test, everything about it looks perfect. But, that app doesn't attempt to interpret touches as anything other than touches. Maybe I should write a simple app that creates a View full screen and prints out what events it is finding. I've only played around with Android development a few years back but it shouldn't be too hard. It looks like all the possible events (and there are a lot) are listed here:

http :// developer.android.com/ reference/ android/ view/ MotionEvent.html
[G4 General] vegetaleb:
Perhaps a custom kernel can fix it, if it's hardware then you should change the digitizer right?
[G4 General] shook187:
I ended up selling my G4 on Craigslist.. I was lucky to get $400.

But anyways.. I went ahead and repurchased a G4 at T Mobile because I really do like this phone if it wasn't for the touch screen issues.

And I don't know how to say this but I personally think you guys with the touch issues are out of luck if you think a software update will fix the problem. I think its a hardware issue because this new phone is night and day when it comes to touch screen sensitivity and accuracy. My new phone is a joy to use now. I recommend those who are waiting for a software update to just warranty it out, because no software update will fix the issue.

FYI.. I'm also on my 5 day with the new device so it isn't like the previous device when after factory reset it ran well for day or two, only to resort back to the touches issues.
[G4 General] Sammae7:
All I know is I really miss my G3. This phone just seems broken. We paid very good money for it and deserve a resolution.

I don't think I can support LG and their next phone after this.
[G4 General] AegisValour:
I think deep down inside we all thought it was a hardware issue, but just kept on hoping it would be fixed via software.

Damn that real disappointing.

Question why not use the warranty to get it fixed or a new one?
[G4 General] SecondRoom:
hi all..

got the g4.. screentouch issue here also..

a massive problem when i try to zoom in/out in pictures and the browser..

the device work perfect only when its in my hand so in this way i understood also that its a

'grounding" issue... i think u all need to read this one (google it cause i cant post direct link):

Fixing the ghost touch/grounding issue once and for all! (Hint: it was never a software problem)

gonna try it tommorow..
[G4 General] AegisValour:
Was this the one you're talking about?

LINK

Either way that looks complicated and might be a too much for most of us. Interesting read though, but wouldn't try it myself.

Let us know how it goes, as I recall someone here mentioned he fixed it himself with some prying but never went into detail.
[G4 General] SecondRoom:
hi

yes.. that's the link.. i'm almost sure that is the solution for my issue - "grounding".. cause my the device works flawless

if its in my hand or connected to the usb cable that connected to the pc.. in fact u can put

the device on any surface and just give a little touch on his side body while testing and u can

c everything work well.. (in my device anyway..)

u can take the device to some phone lab they can open it and just guide the guy there to check

in this dirction and to fix the problem.
[G4 General] Hendrycks:
I was ready to return my G4 as I got it 3 days ago and was having touch issues. Brought it back to Telus and said I wanted to try returning the glass screen protector I was using and then seeing if that fixed the issue. Now without any sort of screen protector it works flawlessly.

When I looked closely at the protector it had a bit of a difference between the screen and it as the phone slightly curves. If I pushed down lightly in the middle you could feel the protector VERY slightly flex so this must be where some of the problems are.

I'm not sure if some people here don't have anything on their screen but if you do it's worth a try to take it off as I've gone from hating the phone to actually thinking it's the best phone out there right now.
[G4 General] player911:
I don't use a screen protector and the screen is fine. It does miss touches although I have "show touches" turned on in dev options. I can SEE the taps being registered. It isnt a grounding issue. The screen senses it but something beyond that isnt responding properly. It is a software bug. The phone reacts exactly the same whether it is plugged in, being used 1 handed, or held. My Nexus 7 2013 has grounding issues. The G4 does not. I firmly stand by my belief that it is a rogue background app or service that is temporarily causing a hesitation in the software and "skipping" to catch up... missing any inputs in the process.

Once we get a custom rom, we'll see. I bet this goes away with a CM rom. Maybe even a debloater app
