I have the US T-Mobile version. I sometimes think I might be missing a tap, but I can never be sure if its just me missing the spot or the actual issue. This happens maybe once or twice a day. If I didn't know about this widespread issue, I would shrug these missed taps off as just me being clumsy.
[G4 General] Snakecharmed:
After enabling Force GPU rendering, the responsiveness has not improved. I haven't gone back to untick the option yet, but needless to say, all these fixes only seem to work briefly. After prolonged use, the problem always seems to come back.
[G4 General] barondebxl:
That'll change in a few days unfortunately
[G4 General] BoldCasual:
You're actually spot on here, as soon as I pickup the device multitouch works flawlessly. But lying down on a table/bed it doesn't work at all. What the hell? So obviously a software bug, albeit a very random one. Thanks for the tip!
[G4 General] brapicoco:
Lol! It looks like you're wishing it to go wrong..

Anyways, is this really a hardware problem? Others have it others don't

If it's software then almost all users should have it since all are running the same software.. Just thinking..
[G4 General] atsitalian:
I have had the phone for about a week and just received an update from at&t and it looks like my touch issues are resolved.

Nevermind. Looks like my update to H81010e just took a long time to get to me.
[G4 General] pepporony:
Have this problem too...

Lying phone down on bed and the multi touch won't work...
[G4 General] Snakecharmed:
Now trying the SGS TouchScreen Booster app and probably going to enjoy it for the 4-8 hours that it works well before it inevitably also becomes ineffective and useless.
[G4 General] frope01:
I tried that. Even tried the force GPU rendering. Nothing has fixed it.
[G4 General] gtg465x:
I have had my G4 for almost 3 weeks and haven't had this problem at all. It's an unlocked H815 SEA variant, made in the LG motherland Korea. To me it sounds like some G4s have defective touchscreens because a lot of people have said they exchanged and the new phone didn't have the problem.
[G4 General] coolmaster121:
Here is the test I can do and it will fail 100% of the time.

Hi coolmaster121, can I add your test to the OP ?
[G4 General] coolmaster121:
Go ahead
[G4 General] arcteryxbird:
This is the most frustrating touchscreen issue for me. Double tap to wake doesn't seem to want to work well, especially when charging. In this case, it didn't work at all: https://www.youtube.com/watch?v=gzI9FaOB49M
[G4 General] rsbenedict:
I get the same thing. It generally works, but when charging, it won't work at all. :(
[G4 General] shook187:
I just tested using the same Antutu app.. I get a similar response for anything past 5 finger. So does that make my screen defective?
[G4 General] IlyaKol:
TWN H815 with no issues.
[G4 General] shook187:
Now stop me if I'm wrong aren't certain screen supposed to handle only a certain amount of multi touch? It just appears that LG can only handle no more than 5 multitouch. Does that necessarily mean its a defect? Who actually used or needs 5 fingers gestures anyways?
[G4 General] coolmaster121:
I have issues that are random with missed taps when typing, or the phones does a tap instead of a swite etc. This was the only way I can see a consistent issue I can reproduce a visible touchscreen issue.

I am planning to stop by a Tmobile store to get it replaced under 15 days consumer
[G4 General] shook187:
Don't waste your time, I'm on my third G4 and they all displayed this kind of behavior. It seems that the t-mobile version of the g4 is suffering from this issue
[G4 General] coolmaster121:
The plan is to test the new device in the store and if it has the same issue Ill be asking for a refund etc... I dont want to have another OnePlus One situation on my hands.
[G4 General] josephcory:
I'm stumped as to what's wrong with LG G4's touchscreen
[G4 General] shook187:
Good luck because fresh out the box the G4 performs well.. But after a few days is when you'll start having problems.
[G4 General] redeyss:
I have the keyboard swipe problem. It drops touch during swipe and I end up with two words instead of the word I'm trying to type. Happening now as I type this. Also missed taps and missed dt2w. Really killing the experience for me. Had similar problems with G2 and G3. Looking at S6 active later today.

It's pretty close to unusable!
[G4 General] jaggrey:
This is the main issue I'm having with the swiping on the keyboard. It's annoying. Other than that I don't think I'm having missed taps.
[G4 General] barondebxl:
It's not just the T-mobile G4, it was happening in my international H815 version.
[G4 General] Semantics:
I had the exact experience with the G4. Never with the G2 or G3. I agree the G4 was close to unusable, and won't get another until this gets resolved. I don't buy Samsung, so I'll stick with my awesome G3 for a while longer.
[G4 General] redeyss:
I've got a warranty unit on the way, will report back.
[G4 General] liamR:
I got my new replacement unit yesterday, same problem (but better in overall, maybe because of the GPU rendering trick) :(

Now I have to decide if I want to wait for a fix for LG (update) or return the G4 and go/wait for another device (which will be too bad as I really like this phone).
[G4 General] brapicoco:
It really is a shame. I wanted to replace my iphone 6 with this but if the touchscreen is useless then it's gonna be s6 edge. What a waste from LG
[G4 General] redeyss:
Question is how fast can they update? Carrier versions of an ota will need to be certified which takes time. Could be two months or more for at&t? Will root and recovery come first so we can flash a stock updated rom like Cloudy? Reports of LG lowering G4 sales expectations in the news and now this huge defect in their shiny new flagship, doesn't look good for them.
[G4 General] WheresTrent:
I'm returning my replacement and probably going for an iPhone 6+. Sorry everyone. LG, ya blew it.
[G4 General] Snakecharmed:
I feel everyone's frustration. It's really inexcusable that this issue managed to slip through the cracks undetected during production. This is literally the only outstanding issue I have with my G4 and my satisfaction with the phone continues to dwindle with each missed tap. The only real hope I have at this point is that root access will lead to someone finding the actual root cause (no pun intended) of this issue.
[G4 General] kbuck13:
I'm having all of those issues, missed taps, a tap when swiping and dropped missing letters when swiping on multiple keyboards and I have the Verizon version.
[G4 General] frope01:
This is LG's reply to my email regarding this issue. They think that this issue is uncommon. I don't know the stats but it's looking pretty common to me. If more people contact them it may speed up their efforts at a solution.
[G4 General] ambervals6:
They can keep thinking that, because sales stats already speak. LG is doing poor and that is for a reason.

Sent from my SM-G920T
[G4 General] coolmaster121:
Well, I got my G4 replaced yesterday, the new unit seems to work much better with taps. I am still in the process in the testing with swipes, and light taps to make sure that 100% of touches are being registered.
[G4 General] csmall:
What is the version number of the LG Keyboard that they pushed out that is supposed to resolve touch issues?
[G4 General] shook187:
I really hate when people keep saying the replacement "seems better"

Wait a few days before you make that assessment.... I guarantee you it's going to have the same issues
[G4 General] coolmaster121:
1st. Chill the frack out

2nd. This is a 3rd replacement, so I am being thorough and I know when my phone has missed touches and when it does not.

3rd. As far as "guaranteeing" what If it turns out to be perfect, what then?
[G4 General] ruzkay:
OMFG I had light bleed on my first one and was offered cash back if I keep it. But I had already sent it in. Now the replacement is here and it has the exact same light bleed and an missing touches ****ing everywhere... I was thinking the people missing touches are being overly fussy and arent having any real problems... but like this scrolling on websites is nearly impossible. 15 presses to delete 4 letters, can only scroll if I do it in slow motion... Wasted the screen protector again if I send it back!

Is this hardware or software????
[G4 General] supadupa111:
H815 with a tempered glass screen protector on, it is way better than the stock protector. Scrolling is so much better; I never had double tapping issues though.

I think stock protector holds oil/grease easily, messing with the touch sensitivity.
[G4 General] gsxcorey:
My replacement is doing the same ****. S6 active hits tmobile and this pos is gone. Last lg I ever get too if I don't get a fix before I change phones. Did anyone use this phone before release? I mean the keyboard and scrolling through pages? F'n test it for a few days before you release it. This garbage will have me out hundreds of dollars. My wife has the same phone and it misses touches too. Utter garbage

---------- Post added at 04:34 PM ---------- Previous post was at 04:32 PM ----------

I only wish more places would pick up on this thread so it gets popularity. I think that is the only way lg will make it a priority.
[G4 General] ruzkay:
I wonder if it is some kind of memory leak or some process? Because after a restart it seems much better don't know if it is random but it is definitely not Placebo! I couldn't scroll at all before the restart now it works.
[G4 General] supadupa111:
Someone mentioned somewhere turning off dual screen smart settings helped
[G4 General] icecicle:
I honestly can't stand the keyboard lag ? i consider slamming my phone against a wall but then realize how much I paid for it
[G4 General] FMMFL:
I got the same canned bull**** response. Also from Jade.
[G4 General] Ahmed Alshaali:
I own H818P the 2 sim card

And i did the test many time with even 5 fingers and every thing is ok.

Even my friend got H815 the International model its working fine
[G4 General] Snakecharmed:
Regarding the multi-touch, I don't think that's actually an issue. In the SGS TouchScreen Booster app, the settings show that the multi-touch points value is maxed at 5. I don't know whether that's the max setting on the SGS2 or if it's reading that value off of the G4, but I don't believe that AnTuTu test really tell us anything with regard to missed taps. The G4's screen could just be a 5-point multi-touch versus a 10-point multi-touch.
[G4 General] gtg465x:
You can't guarantee that. I have owned my G4 for 3 weeks and have had no touchscreen issues at all. No missed taps or swipes. Mine is a SEA H815 that came from Singapore. It was made in Korea. Wonder if the issues depend on where your G4 was manufactured. Anyone else with a made in Korea G4 have this issue?

For the sake of data, I do not have a screen protector on and I do not use the LG keyboard. I use the Google Keyboard. Also, I have dual window enabled. My software version is V10a-SEA-XX.
[G4 General] siraltus:
H811 T-Mobile USA variant here, absolutely no touch issues at all. The only thing I have to remember is to double-tap slowly to wake it up, but that's normal because my G3 was the same way and my Nexus 9 is the same way, too.
[G4 General] herzzreh:
Do they not test anymore? How did this get past beta?
[G4 General] liamR:
That's why you should link them to this thread. 65+% experiencing this problem from 400+ users survey that's more than pretty common to me...
[G4 General] FMMFL:
I know you didn't quote me but LG sent me the same email. I sent them a link to this thread and about 5 other tech articles headlining this issue. And I sent it to them on June 16th. So it's not like this was shocking to them.
[G4 General] AegisValour:
After 2 days of use, I'm pretty sure I have touch issues. Though I think I'm on the lighter end of the spectrum that is missing around about 10% of my taps/touches. However, oddly enough my double tap to wake works 100% of the time which leads me to believe it is a software issue.

I believe LG set the screen sensitive lower (think the opposite of glove mode?). My reasoning is that it has something to do with the lock screen feature where you slide from the top to glance at the time as mine is very easy to activate. Basically in order to prevent it from activating in pockets the sensitivity was toned down.

My idea does not explain why some users do not miss any touches, but those like the ones in the videos (missing 40% of touches) are clearly hardware defects.

Of course me missing touches could also be in my head since I read all the posts prior to getting mine and it also passed the touch test app up to 5 fingers. Mines could be perfectly fine but I'm too damn paranoid about my phones.

Important to note is that it passes the touch test up until 6 fingers where it bugs out like crazy, but none of my previous phones would bug out and could handle 6+ fingers tests. If anyone who has one they believe has no issues test 6 fingers and let us know if it bugs out. Could this be also possible signs of hardware defect?
[G4 General] frope01:
Did in a live chat.
[G4 General] Stew503:
Problem solved!!!

I had this same problem with my G2 after I upgraded to lollipop. On my G2 I had enter a dialer code to get into the hidden service menu and basically recalibrate the input devices on the device. I have been searching the web since I got the G4 for the dialer code for the service menu but I didn't have any luck. After messing around with gestures options within Nova Launcher I found the service menu. Here is what I did.

From the home screen,

>Nova settings>Gestures and Inputs>Pinch In>Shortcuts>Activities>Service Menu

From the hidden service menu,

>Service Menu - Auto test>Press volume up twice>Press volume down twice>Cover screen with hand>Pull hand away from screen >slide the arrow at the top left of the screen to the right.

Done!

I just typed this whole post with no mistypes! Hurray!

---------- Post added at 09:53 PM ---------- Previous post was at 09:25 PM ----------

Someone should call LG support and demand that they give out the service menu dialer code for all variants of the G4. Then post the dialer codes on this forum.
[G4 General] kingwaffle:
This isn't applicable to the G4. Those options don't exist.

Service menu is 277634#*# btw

Edit: actually, they do...they're just not in the place he said they were. Hit the 277634#*# above then device test -> SAAT -> Manual Test -> Key Press Test

It doesn't seem to help anything, though.

---------- Post added at 06:08 PM ---------- Previous post was at 05:56 PM ----------

I agree with you in that it feels a lot like a misconfigured driver that is causing these issues. I noticed if you are slow or heavy with the taps, it feels fine. If you are a light tapper or quickly tap around, it tends to miss stuff.

My touchscreen freaks out on that Antutu test when I get about 9 fingers on it, and it shouldn't do that. Seems like a software glitch instead of faulty manufacturing.
[G4 General] Stew503:
Here is a screen shot from my G4 of the service menu I am referring to. It apparently is different from the menu you are accessing with 277634#*#. 277634#*# does nothing on my Sprint LG G4.
[G4 General] Stew503:
Screen shot.

Here is the screen shot.
[G4 General] AegisValour:
Well said, at happens mostly during these quick taps/swipes.

Hm, most people seem to be able to get up to 6+ fingers on the test. I'm beginning to wonder if I should just exchange it then.
[G4 General] shook187:
I get 5 no problem sometimes 6 sometimes 8... my question is are you going to use this test to return or exchange your phone? You'll look pretty ridiculous showing the sales clerk, your phone is broken cuz you can't put ten fingers on the screen at one time. Who the hell put that many fingers on the screen anyway?
[G4 General] AegisValour:
Yeah I know what you mean. Honestly, I don't care that I can't put more than 5 fingers on my device.

My real concern is that I am missing an occasional tap/swipe, but I can't necessarily recreate as it happens seemingly random. We pay good money for these devices, so it's not acceptable to have this kind of problems on a touchscreen device.

Like many others, if LG just stated that this problem was software based then I probably would not exchange it. I would like to believe the reason for the delay in statement is that LG themselves are not 100% certain if it is software or hardware.
[G4 General] 06stang:
Just got this from LG Twitter. He says just kidding at the end though. (his initials lol)

And in my opinion it's not hardware issues. Every app I download and even the built in touch showing options in Developer Options shows every tap and every swipe. It's the software not picking it up at certain times.
[G4 General] arcteryxbird:
I agree that it's software based. My AT&T G4 has passed every multitouch test I've done with flying colors. But then it'll miss double tap to wake, screen taps here and there, etc. As I've said elsewhere, this is just more evidence of how terrible LG is at making software. There's the ugliness of their UI, and they broke the G3 with their Lollipop update. The G4 should have insanely good battery life with the 808 SoC and the rather large battery, but I'm getting just barely better battery life out of it than the S6 that I tried. Then, there's this touch issue.
[G4 General] Snakecharmed:
I'm glad that there are people at LG addressing it with more conviction than a copy and paste generic email response. I do believe it will get fixed, just like I do believe we'll have a publicly available rooting method in due time, but the phone feels really incomplete until we get these two things. I signed up knowing about the latter, but the former even being an issue these days just boggles the mind.

Also, Roots, centrifugal, or twin screw?
[G4 General] 06stang:
As long as it's not hardware then I don't mind. I wouldn't even mind LG ignoring the problems as long as we get root and our development team to get us some amazing ROMs.

Twin screw Saleen. Sold it two years ago once stock mustangs started keeping up. Saw more value in a new truck and bike instead.
[G4 General] player911:
7 fingers will make the screen go crazy. I tested this in YAMMT and same results.

I can even make the screen do extra taps by using 5 fingers, tapping 8 times quickly (or more) and holding my fingers to the screen on the last time. The screen still pulses "please touch screen" a few more times even though all 5 fingers are solidly placed on the screen.

It also gets whacky when I rotate 5 fingers quickly for a few seconds and stop suddenly.

I can even make 3 fingers go crazy by slowly swiping 3 fingers from left to right on the home screen with "show touches" enabled. Doing so causes 2 and 3 to jump back and forth like they get confused.

2 fingers seems fine thus far.

A few more tests to try,

Uh oh
[G4 General] ruzkay:
2 Times I used my phone in the sun and it goes crazy zero reaction. Every single swipe randomly clicks around the screen... I restarted my phone and went inside and it works flawless. Maybe the phone doesn't like being hot or something about the light sensor?
[G4 General] fineazbro:
last night i just remove that Icarez matted screen protector off my G4 and just try it like that to see if i still have the touch screen issue but to my surprise all touch screen issue are gone, i cannot believe it i had that screen protector on the minute i open box, should of try it before...now i feel better.
[G4 General] wernerzero:
There is a missed tap every now and then, but that's been the case with every smartphone I've owned.

Outdoors is another story... I have tap several times and try shielding it etc. Seems the bright sun affects the sensivity..?!
[G4 General] frope01:
There is one definite in my case. It gets considerably worse when trying to use the phone while it's charging. Even if the phone happens to be running smooth at the time using while charging makes it worse. My screen protector had no effect at all.
[G4 General] 06stang:
I tried six fingers two toes and a baseball bat on the screen and it still messes up. Unacceptable. I like to type with a wood bat and if lg has a bug with it.... I won't accept that.
[G4 General] ruzkay:
Yeah that is absolutely weird... How the heck does light afdect the touch I kinda assumed it must be getting hot but it didn't really feel hot...

I wonder if other people except you and me link the problems to bright sunlight.
[G4 General] 06stang:
I've noticed the screen won't turn on at night. That's weird right? After about 8pm the knock on doesn't work and when I use the power button the screen will flash on for a second and right back off. I figured it was because I was doing it too fast but even if I start with a single power button tap it still does it
[G4 General] redeyss:
Is there actually a poll or are we just answering in this thread? G+ poll would be good.
[G4 General] shook187:
That's because if you cover the proximity sensor, knock on won't work. It's a feature so it won't turn on accidentally while in your pocket.

So in the dark the proximity sensor is sensing darkness.
[G4 General] 06stang:
Never had a sensor that sensitive before. Maybe it's the tempered glass. Great job figuring it out.
[G4 General] liamR:
If you have good quality tempered glass you shouldn't be worry, I tested a few different brands and all of them didn't affect the proximity sensor in any way (you can test it in the Service Menu).
[G4 General] busab:
I've noticed the unresponsive screen since day one. It's driving me nuts! I'm probably going to send it back and reactivate my Nexus 6. Sucks because otherwise I really like this phone.
[G4 General] chriskwarren:
Had a few issues with touch when I had my Spigen crystal film on it. Using the LG keyboard helped me a bit. Figured my issue was just software as missing scrolling and such did not happen too often.

I took the Spigen film off and put the Orzly 0.24mm tempered glass film on and now I have more issues missing swipes and taps. I'll probably have to take the tempered glass off and try the Spigen film again. (or try a thinner glass...I was looking at a 0.20mm one the other day in a thread here somewhere..I'll have to search that one up).
[G4 General] hdyim:
I've had my LG for about 4 days now. Noticed some issues throughout this time and was well... in slightly optimistic mood, that LG will fix it with a software update. Now I just sat in my backjard in direct sunlight and that made the issues far worse. It sometimes took me up to 10 slides to get to the second homescreen, not to mention how many simple taps were lost. That did it for me and I'm sending mine back right now. Maybe will order one again, when at least that issue is fixed (besides laggy browsing experience and some other minor ones).
[G4 General] aygul12345:
Is this being fixed?

I've noticed if you take the smart notice off the home screen the lag on there goes. The keyboard I dont like anyway I've gone to Google keyboard and I've no lag at all now. I'm on Vodafone UK
[G4 General] player911:
I use Nova and tried other keyboards, but I really like the LG one. I used Flesky for about a week and uninstalled it. I have Smart Notice and Dual Window Mode off. I can tell it still misses a touch here and there but it is so rare that I can barely notice it and it is in the window of normal. They can probably turn up the sensitivity
[G4 General] 06stang:
"Nope?"

LG has stated it's a problem and an update is being worked on.

[G4 General] csmall:
I switched to Google keyboard and so far I haven't experienced anymore missed taps other than when the phone is sleeping and I try to wake it up with knock knock code. While I'm using the phone it seems to respond to my taps now. Maybe the issue was just with the LG keyboard. At least on my unit.
