I'm doing the same. Still missing swipes in the middle of a word sometimes, ending up with two words instead of the one I was swiping. LG keyboard and Swiftkey seemed worse on the missed swipes.
[G4 General] Ken4G:
I still have random misses even with the Google keyboard. For example, I'll type a few letters and then tap a suggestion up top. It sometimes does not trigger a tap on the suggestion. That along with random misses in other apps is getting a tad frustrating. I have faith LG will come up with something.
[G4 General] Illmatic662:
This thread made me do two things, first update to see if there was a difference with the touchscreen (To me there are big differences) and two it made me get Google Keyboard, how did I live without this thing?
[G4 General] player911:
I am not a fan of Google keyboard. I use it on my Nexus 7. I like a dedicated number row because I am an IT admin and input numbers alot. I tried Flesky but it was aggrevating. I do not like keyboards autocorrecting me.
[G4 General] josephcory:
this is a superphone they must be doing some kind of research on their touchscreen I think
[G4 General] csmall:
You can enable a number row, but it sucks.
[G4 General] BrokenWall:
I noticed there is a definite issue with this phone when I try to use it while on my Motorcycle.

My old Moto X would detect every touch without any problems. When mounted on my handblebar mount using my gloves (which work with touchscreens) the Moto X would still detect the touches without issue, sometimes I just had to make sure I was touching with the right section of material.

My LG G4 using it on my Motorcycle handlebar mount, trying to use the phone at a stop light, is ridiculous, I have had plenty of times where I have had to pull of the road, take off my glove and still wrestle with the phone.

At this point I am only using the G4 because the battery lasts for awhile, I will probably be going back to the Moto X PE when the 2015 model comes out.
[G4 General] MatanYeho:
Comeone LG, fix it!!!

There is no changes for who got OTA update to 10B / 10C version?

what we should do?
[G4 General] 06stang:
I have zero problems with my phone now. The screen protector causes sensor misreads but other than that it looks like I'm one of the few that got a good phone.
[G4 General] gboybama:
This issue is a killer. Try playing a game where timely touches matter. Half of my attempts to drop troops in Clash of Clans fail. This never happened with my HTC M7.
[G4 General] AegisValour:
So has LG addressed this as a software or hardware issue yet?
[G4 General] atsitalian:
Looks like the at&t update from 7/1 may have fixed the issue http://xdaforums.com/g4/general/att-software-update-7-1-15-t3147812/page3. I'm updating now!!

Update complete and the phone is much more responsive and the touchscreen issue appears fixed. I am a happy camper now!!!
[G4 General] atsitalian:
See below. Definitely a SW issue
[G4 General] sharpehenry:
Seems like Sprint, AT&T, and Verizon are receiving updates, why is T-Mobile so quiet?
[G4 General] shook187:
We got our update 2 weeks ago
[G4 General] sharpehenry:
Oh was that it? Haha... We got it so quick for a moment there I thought there was another one.
[G4 General] gboybama:
Early results look like my AT&T version was helped greatly by getting today's update. My touch screen is a lot more sensitive now. Not sure if it's perfect yet, but certainly improved.

My Swiftkey can now select the middle word suggestion reliably and the knock to unlock has worked with two light taps every time I've tried but once.

Previously, I had to knock about ten times in a row to get the thing to wake up and the middle suggestion on Swiftkey never worked on the first try for me.
[G4 General] csmall:
AT&T update seemed to resolve my touch screen issues.
[G4 General] jaggrey:
Was it mentioned in this thread that the issue of swiping seems to be much worse when the phone is flat? I just realized this.

Anyway, I hope T-Mobile updates the phone soon.
[G4 General] Sammae7:
Yeah, the AT&T update fixed my scroll/click issue but it seems like my tap to wake is acting up now. Occasionally it refuses to work and I have to use the power button.
[G4 General] anwar08:
Facing an issue where am unable to pull down the notification bar when the mobile is placed over some soft/Flat surface. Even multi touch app does not detect any taps. Sometime when swiping the notif bar, it recognizes that as double tap and locks the screen.

H818N model
[G4 General] faizalotai:
Is it on 10e or 10g?
[G4 General] darkstreets:
Exact same issue here. Even after the update it's still the same. I'm thinking of returning the phone, I had just about enough of it!
[G4 General] anwar08:
Its in the service center for the past 4 days. No response yet. Worst after sales service from LG
[G4 General] Culex316:
Dude, I've had the phone for a little over two weeks already and I am STILL not experiencing any touchscreen issues on my unlocked G4 H815.

The only thing that occasionally doesn't respond immediately (after its been asleep for a long time) is double tap to wake (have to tap four times) but other than that, I can scroll and swipe smoothly.
[G4 General] jaggrey:
Interesting you said flat / soft surface. When I posted that I was on the bed. But I've realized that I haven't had an issue when swiping when it's laying on the table, like I'm doing now. Maybe coincidence.
[G4 General] flamadiddle:
Question to those who answered No. I Have No Issue Whatsoever. to the poll:

Do you have the Knock Code enabled?

I have a theory that a lot of these missed taps might be LG's UI waiting for the second "knock" to see if you did a single or double tap on the screen. So if you disable that, the missed taps might go away. Just a hunch. I'm about to buy this phone next week (I think), and I have no interest in using the Knock code. I prefer pressing a real button anyway. So I'm wondering if that will fix the issue that most people are experiencing, since I'm guessing most people leave it enabled.
[G4 General] AegisValour:
Interesting theory, I will look into testing this out myself today since my touch screen issue seems to have gotten significantly worse to where I am considering exchanging for an S6. For others who want to try this as well but can't seen to find a way to disable it. I used this method from reddit.

LINK

I would also like to know if there was a way to disable the slide to preview option where it previews the time when sliding down on a locked phone.
[G4 General] flamadiddle:
Thanks for the link. I had no idea some carriers hid that option, although I can't say I'm surprised. Things like this are exactly why I want root/bootloader unlock.
[G4 General] anwar08:
The issue i have is mainly on soft surface. when i use it lying on the bed or kept over a cushion chair or purse.
[G4 General] frope01:
I've been doing a lot of testing since the last (AT&T) update. My touch issues, including knock code and keyboard swipes are gone. My touch issue was at its worst while plugged in charging. That's also gone as I'm writing this while charging which used to be a nightmare.
[G4 General] roosta:
Happy to report my MADEIN TAIWAN dual SIM H818P model sourced in UAE has zero issues. Not a single missed tap/swipe using play store tap test apps... Phew! Very happy I haven't ran into the issues described.

RoOSTA
[G4 General] aygul12345:
Can you really confirm the issues are gone?

[G4 General] roosta:
Ummmm...I don't know what else to say - I've never had the problem for it to "go away".

Ive never experienced missed taps/swipes and I use a thick TG screen protector. So no "fix" here, as I never needed it.

[G4 General] Mr.Kakarot:
Bell LG G4

Lg h812

Knock knock almost never works...

I am on my second lg G4 from bell... Exact same issues on both. Touch issues while typing, swiping but more importantly....GAMING! I have a very hard time collecting coins, doing anything really.... Typos out the yin yang... And in clash, missed spells, troops not switching.... And if I try to hold down archer and barbs to build at the same time, it does nothing.... Pure trash
[G4 General] barondebxl:
But the fact that you have to double tap 4 times still shows an issue. Good thing it isn't as bad as others.
[G4 General] Culex316:
I mean, day-to-day usability like scrolling through web pages, e-mails, navigating menus etc does not really feel hindered or impaired in any way. If it bothered me that much I would have sold it already.

I hope at least that a future OTA will solve the issues the rest of you guys are having.
[G4 General] barondebxl:
I moved on from the G4 personally. But as long as you have no issues then it's a good thing.
[G4 General] superbonto:
i recently discovers that my G4's screen behave quite weird on specific condition: placed on a car mount.

my touches are hardly registered upon touching my phone in an upright position.

no such issues appeared when using with my hands, lie my phone on bed or table, etc.

still bearable for me.
[G4 General] tymansdaddy:
I've had 2 different ones from T-Mobile with the issue. The manager when doing a factory reset said man this thing is going crazy. Lol. I'm on an M9 now. I still have 1 week to get another G4 if the problem gets fixed. I really want my G4 back.
[G4 General] SWiSS BOSS:
Using H815, I was not able to detect any issues. some taps may miss if you really barely touch the screen, but I don't believe this is the the problem you are talking about as most see it as a game-breaker...
[G4 General] nsmal24:
My g4 (vzw) has the same issue as everyone else. Has anyone EXCHANGED theirs and gotten one without the issue? It seems to be fairly global. It is slight enough for me that it just makes you doubt the accuracy of your tap. I'm wondering if those without the issue just aren't noticing the problem. I've been opening QuickMemo, choosing the pen, and tapping all over the screen watching every tap. It seems that I miss about 1 in 10 taps (not specific to any section of the screen). I will contribute to the LG support case when they open this morning.
[G4 General] Snakecharmed:
The only thing I seem to notice is sometimes a double tap to wake doesn't register about maybe 5% of the time, but I don't have issues with it when the double tap is more deliberate.
[G4 General] nsmal24:
I just talked to LG Chat Support. She recommended a factory reset then sending the device for repair. I said that was unnecessary since I can exchange it still. Bleh.
[G4 General] ecpolo521:
I had this issue and asked to exchange the phone. Plus, my screen gets washed out in the sun and a had blue tint when starting up camera.

I'm hoping the replacement doesn't have any of these issues. If not, back to my Nexus 5.
[G4 General] Batfink33:
I used to see this issue on my old Chinese phones. Can't believe my G4 has it. Is it a hardware or software issue?
[G4 General] player911:
It is very unnoticeable. It only happens occasionally.

It doesn't seem like a hardware issue. Almost like a background process is "freezing" the system for a millisecond.

I am kind of leery because my Nexus 7 2013 had a grounding problem and was really bad. I couldn't play games at all. There were hardware mods to help "ground" the touchscreen cable but honestly it doesn't seem to really help.

The G4 is no where near at bad, near perfect. I just notice a "tick" on the occasion. Definitely something I pay attention to with a new device now.

I haven't done a lot of testing with it but it seemed to be worse when plugged in.

Things to looks for:

Worse when plugged in?

Worse when not plugged in?

Worse immedately when turning on?

Worse after a while of use or gaming(heat issue maybe or throttling CPU due to heat)?

It could be a sensitivity issue. Several people have reported this to help:

If you find a good setting, post it for all to use.
[G4 General] liamR:
I tried this app, didn't do anything to my device, maybe others have a placebo effect.
[G4 General] player911:
Perhaps. I haven't tried it. Just offered a suggestion.
[G4 General] didi_ghost:
I think that was discussed here that is normal with this device. It's just the way the screen it is.
[G4 General] darksulfur5:
I have the T-Mo variant (H811), that didn't work either. Any idea what I can do to test it?
[G4 General] coolmaster121:
What version of Software are you guys running (who have the touch issues)?

I am running H81110d
[G4 General] JedixJarf:
Tempered glass and no issues here.
[G4 General] liamR:
Someone here suggest to test it in QuickMemo+.

You can choose thick marker and tap on the screen.

Edit:

Found the post -
[G4 General] Kristen21:
I just came from a s6. The missed presses on the G4 is frustratingly noticeable when I'm trying to type. It's slow to respond IF it does end up catching the letter I just touched. The G3 felt way faster in every way, typing, picture taking, sending and receiving texts. I'm debating going back (gulp) to the s6 or possibly sucking it up and paying for the nexus 6. I'm not sure I can wait to 'see' if this gets fixed in an update.
[G4 General] legend221:
Temporary fix is using a 3rd party keyboard like SwiftKey. People are noticing lag on the LG keyboard which can make the lag worse.

Also the S6 does have a better processor so the difference should be very similar but it will not be faster than that flagship. Depends who you ask.

.: Sent from my 'Android til I die' Phone or Tablet :.
[G4 General] Kristen21:
Darn that's what I'm using, SwiftKey.

I don't expect it to be faster than the S6 but equal, yes. My M7 felt faster than this lol
[G4 General] olivercervera:
I do loose some touch/tap, if not so strong. I am using a tempered glass screen.

International version H815
[G4 General] rsbenedict:
I'm noticing most of my issues with knock code and you're right that it seems nothing responds when plugged in. It's becoming annoying. :(
[G4 General] josephcory:
I'm not giving up this phone even it this is a hardware issue
[G4 General] vegetaleb:
Looks like only US variant have this problem, no?
[G4 General] Sammae7:
Mine is 10g
[G4 General] Shimpossible:
I've noticed that while plugged in I can register all 10 touches. While on battery, the screen goes crazy at the 6th touch. I've tried this on 3 different phones and they all behave the same.
[G4 General] I Like Soup:
I'm coming from a G2 and a G3. I bought my G4 on June 25th and I've certainly noticed the lack of responsiveness on the screen. Sometimes I'll have to double tap to wake two or three times. When it is plugged in, it takes several tries and with very heavy taps to boot and there are times I've given up and simply used the back button. I've also noted pulling down from the top to see the time/notifications has been a little sporadic as well. All in all, there is definitely something wrong, even with the LG Keyboard update and running the latest T-Mobile software. I absolutely love this phone, the feel in the hand with the curve, the leather back, the screen, and the smoothness of the device. However, I may end up taking it back in before my 14 days are up and get another one hoping it will either be a later manufacture date or simply a phone with no issues. I'm not really sure how that effects the promotions I've sent in for (with the IMEI number), but may as well get another new device just in case. It can't be worse, right?
[G4 General] frope01:
You'll still get your promotional items. I exchanged my first G4 due to the touch issue only to have the same issue with the new unit. I still got my promotional charger, battery, SD card combo. I'm on AT&T and the latest update has solved my touch responsiveness problem so now I'm sure it's a repairable software issue.

It's 10g.
[G4 General] liamR:
I have a few friends that also got the G4 and they were 100% sure that they don't have this problem. I took their phones and showed them that they do have this problem. That makes me believe that people who don't think they have the problem in fact do have it but they don't notice it.

The new update doesn't fix it.
[G4 General] 20degrees:
Go to keyboard selection, select Google keyboard for typing. Then go to app settings, find lg keyboard, force stop, clear cache, clear data and reboot phone.

Type up a text with Google keyboard, see if problem resolved?
[G4 General] liamR:
Thanks but I wasn't talking about the keyboard, I'm using SwiftKey without any issues. The real problem is KnockCode/Tap to wake and some missed taps when just using it.
[G4 General] 20degrees:
Well I got a replacement G4 and did the update, reset the phone and never used the stock keyboard. Accidentally 1 day the stock keyboard got selected, it started having touch screen issues all around (not just typing) so I did what I posted and they all went away. Might be able to do with Swiftkey too and not Google keyboard.

Did you ever use the stock keyboard?
[G4 General] Babak678:
LG G4 Touch screen issue is present in Canada as well 😕

To all Canadian LG G4 buyers, the touch screen problem is alive and present in Canada as well. I bought a Wind Mobile LG G4, everything was fine at first but once I plugged it into the charger, it started to to miss touches and being unresponsive (the touches won’t register on the first try) the good test is when you double tap to wake or sleep OR when you go to phone’s setting and touch “about phone” or something else and it misses the first touch. It SHOULD NOT miss any touches, period. I put it next it to my LG G3 and on my LG G3 double tap to wake and sleep worked every time and no missed touches in the phone setting either, when it was plugged into the charger.. but it didn’t work on LG G4 which is unacceptable for $700 phone, once again it only happens when you PLUGGED IT in to the charger, if its disconnected it works fine. I returned that phone
[G4 General] AegisValour:
Mines is also from WIND.

The issues persists plugged in or not. For me there is no difference when plugged in or not. Though the issue is worse when the phone heats up.
[G4 General] player911:
I have a new LG x8.3 tab that was released with the G4. It experiences the same issues. I occasionally get the static flash on my screen and randomly the system just pauses. Touches are being seen but the software just hiccups and misses touches.

I use LG keyboard on both. My G4 got an update but my tab did not. Just fyi
[G4 General] josephcory:
there must be a problem with tempered glass covering up the proximity sensor or blocking it from reading right
[G4 General] liquidraven:
No Verizon update?
[G4 General] malnash52@gmail.com:
forcing gpu rendering should help with the touchscreen issue
[G4 General] player911:
Verizon got the update as a OTA update. We are now running 11A version of the rom. There was not a separate keyboard update.

I still get misses occasionally. My keyboard does the same thing it did on my G2. It will hiccup, lockup, crash, highlight all of my text that I entered, and replace it with the last few characters I inputted. The keyboard is definitely buggy.

My Verizon X8.3 Tablet does the exact same thing, except it has longer pauses. The tablet will just randomly lockup (but I still see the "Show Touch" cursor).

My Verizon X8.3 is rooted. I should go in and manually remove/debloat it and/or run logs to see what causes it. Probably won't help since the G4 International is rooted/unlocked. But it is something in the software.
[G4 General] liquidraven:
Can we disable knock with Verizon edition?
[G4 General] AegisValour:
I don't have a Verizon model, but you can give this a try.

LINK

FYI, it did not help the touch screen issues.
[G4 General] josephcory:
I called LG and they said the G4 has a factory installed screen protector removing your aftermarket protector helped me a lot
[G4 General] liquidraven:
Were they referring to the gorilla glass lol
[G4 General] zkyevolved:
Guys, I'd like to chime in. I've had my device for 3 days, and I'm a fairly fast typer. I haven't seen the issue. But the first thing I did was install nova prime and touchpal keyboard - they both allow backup and syncing so when I change devices they're always there for me! :)...
[G4 General] Sammae7:
After various updates on my software and a few apps I decided to do a factory reset, which seems to have made things worse. My touch issues have returned and my phone seems to be heating up quicker, which in turn is making my brightness jump around.
[G4 General] callousparade:
I've been having the same issue, Verizon g4 with a naked screen, primarily when typing (swiftkey).

Messing around in developer settings, I enabled 'show touches'. Oddly I get the missed touches way less often with that enabled, but when does occur it seems more like a typical UI lockup. Ei It'll miss the touch, ignore the next touch or two, and then catch up and input all missed touches. Before, it would just miss that first touch and never 'catch up', pressing the missed key again simply counted as a single touch

Wondering if anyone else has seen similar behavior or if that's meaningful at all
[G4 General] enfurno:
I returned my g4 this morning for a replacement.. So.... I don't currently have a screen protector on and well... Not even skipping a beat... Lg needs to address this issue immediately.
[G4 General] shook187:
Give it a few days... it will be skipping plenty of beats.
[G4 General] enfurno:
Thanks. I always appreciate a positive outlook on things.............
[G4 General] Sammae7:
If I didn't pass my return period up almost three weeks ago I'd probably just take this back and break out my G3. My fiance's seems so smooth in comparison, which is sad.
[G4 General] 20degrees:
Warranty it?
[G4 General] AegisValour:
These touch screen issues aren't 100% recreate able, though at least mine don't feel like it does.

I also think that LG believes it's a software update as the new Korean OTA has touch screen related changes. Thus, they'll most likely ask you to wait for the update.

If anyone has tried it, I would love for them to share their experience (considering sending mine back to LG as well).
[G4 General] shook187:
If software doesn't fix it by the 6 month mark im going to warranty it out and hopefully get one that doesn't have issues.
[G4 General] budeone:
Mine is bad, its aggravating. I suck at typing but my g3 didn't miss anything. I wasn't going to say anything until it was rooted but now that can be a while away. I am starting to think its not software. Kinda sucks!
[G4 General] liquidraven:
For those with knock taking awhile to turn the screen on, download "gravity screen" from play store..it's free and pretty damn cool way of getting rid of screen on/off buttons. I'm liking it.
[G4 General] flyinj54:
I didnt have any touchscreen lag issues until just updating to 10b ota tonight on my eur 815. I was wondering what everyone was talking about with touchscreen issues until i installed this update. Now it's terrible with every other touch not responding. Very aggrevating especially since I wasn't having this issue now i am. Bummer. Very noticeable when swiping between homescreens
[G4 General] Andrea g:
Tpuch screen

The knock screen is so bad I'm just about to take of the lock screen I just got this boneless than three weeks ago any ideas in the fix this problem is not irritating me
[G4 General] vegetaleb:
Damn!

I think I will keep my M9 till all this touchscreen problem is sorted out, I hope LG will fix it soon because the Note 5 is coming in 6 weeks...

Hardware or software culprit is also a good question
[G4 General] marcinek321:
LG G4 Touch response.

Hi.

Im interested to buy Lg G4 but in shop while using G4 i saw that the screen is not responce that screen in samsung or iPhone... When you swipe your finger on homescreen interface are delayed relative to the touch... It's visible when you pull down notification bar too. When i compare it to Note 4 it's hudge difference...

Have anyone have the same "problem" ? The interface isn't moving just under finger. It can bee seen on YT videos when G4 is compare to another phone ;)

My English is poor but I hope all are understant what i mean ;)
