I really hope so. Maybe if they will see it's a major issue they will come out with a fix asap. For now they're (LG) saying they don't know about it and there aren't complaints from users.
[G4 General] prosive:
LG will claim they don't know about it until we raise a storm on social media, support cases, etc. So we need to organize an effort to make things happen.
[G4 General] audscott:
Mine's not severe, on the edges, more than anything. Most noticeable when typing "p". I know it's there so I watch for it. Other pretty solid device for me (other than no Gmail notifications, but I'm not posting about that).
[G4 General] RealEvil_UK:
Mine has the problem. About to return it.
[G4 General] scrillakev:
I just opened up a case with LG.

You should contact them via their live chat and reference the following case number. The more people report this, the faster we'll hear a response back. I really don't want to return this phone.

Really annoying..thought it was my screen protector at first
[G4 General] lazarus2297:
I came from the S6 and I have noticed it as well. I really hope its something that LG addresses.. I want to keep this phone, but its pretty annoying when it happens..
[G4 General] WheresTrent:
I just sent mine back in today for this issue. No screen protector on mine. I have to decide if I want to go buy a replacement G4, or...something else. *dun-dun-duuuuuuunnnnnn*
[G4 General] coolmaster121:
I have had two G4s so far, both brand new from Tmobile. Both have this issue. I purchased one when it was released and the other one 6/8.

Is it possible that the people who are saying that this is not an issue are not seeing or noticing it, but it is still there?

Because if there is an issue with the display, and not all of the units are having it, then this is a Hardware defect, and cannot fully be fixed with software.
[G4 General] esmenikmatixx:
I just came from the s5, before that s4, and i thought i was just not used to an ips touchscreen but then i found this thread so i will try op
[G4 General] liamR:
That's my thoughts exactly. I really like this smartphone, but this issue is a deal breaker for me. I really hope that it's just software fix. I'm not planning to return it for now for replacement as I'm pretty sure that every device is affected (if it's hardware issue, from past experience we need to wait a few weeks or months for fixed batches). I'll give it some time and see what LG doing about it...
[G4 General] mahdibassam:
I have used a tempered glass on my G4 from minute 1, and i notice a very, very, very slight version of this issue, where taps sometimes dont register. it is very slight however, which makes me wonder maybe LG has set the touchscreen sensitivity a tad bit too low, and it could be fixed with an update. Its definitely not a hardware issue, as so many people are affected, and these screens get tested before production with like 5000 taps per minute by testing machines (seen from youtube videos).
[G4 General] jerflash:
I have the same phone and I notice exactly the same thing. It's really not bad at all. I'm running the Skinomi right now and it is perfect fitting and feeling
[G4 General] drt054:
Haven't noticed the miss touches yet. (VS986) but poor battery life is making me rethink this phone.
[G4 General] Semantics:
I had to return mine for the awful keyboard lag making it near impossible to text properly. I'm very disappointed, I really loved the phone but LG messed up a couple of things apart from the screen touch issue.

1. They didn't include smart screen. A horrible omission.

2. They tied Notification volume into ringer volume. You could adjust the notification volume seperately on the G2 and G3.

Even if they fix the screen, with those two omissions, I would probably not go back to the G4 which really bugs me because I love everything about it but those three issues.
[G4 General] daddymikey1975:
The volume issue can be changed with a custom rom. Smart screen could maybe be added with root.

Touch issue.... I dunno... Hoping they fix it asap. I still got a couple days before my 14 is up.
[G4 General] liamR:
I guess that not all the branches are in sync, we should give LG some time to handle it. On the other hand they could be behaving like most of the big companies and deny the problem (and still fix it with an update).
[G4 General] lamzaza:
My have a KnockOn wakeup issue when the screen is off. Only a small part on the screen respond to the knock knock. But G4 from my sis have no problem at all.
[G4 General] jayleekay:
Just a heads up, there's an update to the LG keyboard today. Maybe it will fix some of your issues. I'm using nova launcher and Google keyboard and I don't have any missed touches
[G4 General] Semantics:
Finally got a response from LG USA about the screen issue. They said we are aware of this issue and currently investigating. Thank you.

I don't have the phone anymore but if they fix this I'll go get another.
[G4 General] JaySoul:
I'm not having any problems with the phone - no touch, overheating etc.

The only thing I'd say is my screen certainly seems a lot more yellow than it should be. I think it's the screen colour lottery that others have spoken about.

Tbh I don't mind a slightly warmer colour, as it's easier on the eyes. But whatever.
[G4 General] frope01:
I'm on my second G4. I exchanged the first one yesterday because the touch issue was maddening. Had me seriously looking at other phones. So far so good with the replacement. Let's hope they realize this as an actual problem and roll out a fix.
[G4 General] Culex316:
I just received the international LG G4 H815 and I (thankfully) have no issues so far. Double-tap to wake and sleep work as expected and scrolling is smooth in the web browser.

I am loving this phone and I hope you US LG G4 owners get a fix rolled out to you soon.
[G4 General] generosity21:
I'm on the Sprint variant and the dialer code does nothing for me. Is there any other way to get to that testing menu? I'm having the touch issues pretty bad. Double-tap to wake often takes 2 or 3 or 4 tries before it works, and every keyboard I've used has had issues occasionally (using Swiftkey now). Just interrupting a swipe, or suddenly combining my previous word with my next word, weird stuff like that.

The biggest annoyance is the tap to wake problem. I tried installing the Touchscreen Booster app, and it may be helping when the screen is on, but does nothing to help fix tap to wake.
[G4 General] larsdennert:
No problems on my Verizon Leather Version, fortunately. Maybe I've dodged the bullet. Multi touch works fine. Keyboard has not misses. I would know if there was an issue on mine.

I have owned Smartphones since 2002 including all manner of resistive touch displays on WM like the HTC Titan and Samsungs as well as PDAs back before that to the US Robotics Palm Pilot. I've owned iOS devices; HTC Eris, Incredible, Incredible2; Samsung Galaxy1; Motorola Droid X, Bionic, Razr, Razr HD Maxx, Droid Maxx and now the G4.

Not everyone is experiencing these problems but I believe that people are, frustratingly, having them.
[G4 General] Seth28:
Sprint g4

I just got the G4 from sprint and am having pretty much identical problems. I also use swift key, which had no issues on my previous phone.

touchscreen issues
[G4 General] WheresTrent:
Thanks, that's me who asked. :D

I can at least confirm that this has not helped me in Pinball Arcade. Had a couple of missed taps during a nice game on the Xenon table.

This is probably going back (G4 #2 now), and I don't know if I'm getting an S6, switching to iPhone, or going back to my G2 with borked battery and micro-USB port. Frustrated as hell.
[G4 General] player911:
I think it is a background service. Some reported Dual Screen mode is causing it. Perhaps it adds a transparent layer that adds system load and stutters. I disabled it and it indeed feels more responsive. Ive had hardware touchscreen issues on the Nexus 7 2013 (still unreolved) and this is nothing like that. I use Show Touches from the dev options and I can see the touches making contact even if the app/keyboard doesnt pick them up.

I am not saying there are bad units but I would compare it with display units if you are concerned.
[G4 General] WheresTrent:
I have Dual Screen turned off, turned it off after I got my replacement. No improvement. I had one instance the other day where the phone just wouldn't respond to double-tap to wake up, and it took two or three presses of the power button to get the screen to come on. Just weird all around. Like you, it seems when I use an app like multi-touch tester, it shows every tap.
[G4 General] rsbenedict:
Mine won't wake up with double tap or knock code when plugged into the charger. Sometimes if I tap really hard, it will register, but usually have to use the power button. :(
[G4 General] barondebxl:
I sold mine and ordered another S6. I just think the S6 is a better phone overall, its faster, smoother, supports fast charge out of the box, is already rooted and all plus has a better camera in my opinion. Bye ? G4

---------- Post added at 01:50 AM ---------- Previous post was at 01:48 AM ----------

Wait a few days, those issues will appear. It happened to me after a few days of owning it. Not trying to jinx you but its true.
[G4 General] wadamean:
I had to take off the knock code because it wouldnt always register the taps with the screen off and or on. As well with using fleksy keyboard the touch screen get fairly unresponsive and doenst seem to keep up to my speed and the swipes to space the letters.
[G4 General] aygul12345:
Is this a software issue or a hardware issue?
[G4 General] John Stone:
My Verizon LG G4 has been nearly flawless. The highly annoying exception is that the tap to wake and knock code taps fail to register many times. It seems especially bad after the phone has been idle for a long time, like when I first wake up in the morning. It usually takes 3 tries just to tap the phone on. Sometimes it takes 2 tries to tap the phone on, even if it's only been off a short time. I have not experienced any touchscreen issues apart from that. The phone works perfectly once it's on.

I don't want to return the phone, because I otherwise love it, but the lack of any real acknowledgement from LG has me concerned. I don't want to live with this problem when there are so many other excellent flagships out there right now.
[G4 General] WheresTrent:
That's kind of where I'm at. I want to keep the phone and enjoy the awesome camera; I haven't really begun to explore its full potential. LG being a bit shifty about this problem has me worried they won't fix it, or that it will take a full, agonizing year to do it.
[G4 General] siraltus:
T-Mobile H811 variant here, absolutely no touch issues whatsoever.
[G4 General] :
The same happened to me when I was testing the camera yesterday in the back yard. I tried turning the screen off with the power button and it was unresponsive after many tries. The open with double tap happened a few times too. Luckily I still had my S6 and was able to get a 100% refund on the G4. It's a nice phone but a little too buggy for my taste.
[G4 General] Culex316:
Did you own the International version of a US carrier version?
[G4 General] chriskwarren:
I voted yesterday that my G4 had no issues at all. Starting last night, I began noticing missing taps when using a keyboard (Swiftkey). This am, it misses a tap almost every time I try to type anything. So you are correct.

LG says they are looking into it (I think this news item has been mentioned in this thread already):

http://www.androidpolice.com/2015/0...ur-lg-g4-lg-knows-and-theyre-looking-into-it/
[G4 General] player911:
Supposedly LG released a fix and blaming it on the keyboard service. Anyone know where to find this?

http://www.xda-developers.com/lg-releases-app-update-for-lg-g4-touchscreen-issues/
[G4 General] Th3Bill:
It's in the settings, about phone, app update. Update LG Keyboard

It fixes both the really slow response to long-pressing keyboard for special character as well as the touchscreen tap misses....at least on mine. I wasn't getting missing taps on the main device, but double tap to wake would routinely take 3 or 4 tries to wake device. Since update, no such misses on mine.
[G4 General] chriskwarren:
When I go to that screen, I see a bunch of green checkboxes next to a whack of LG apps (none of which are keyboard-related). I guess that means that those apps are fully updated already?
[G4 General] shook187:
I just took the update...I'll report back.. this device is taking a lot of patience and customization to get it working properly.
[G4 General] barondebxl:
The international H815T. Before that I had the S6 for a month and zero complaints, maybe battery life wasn't the best but in terms of performance the phone just flew through everything. Then when I got the G4, very first thing I noticed was that it wasn't as responsive to the touch as the S6, I texted my buddy right away who wanted feedback from the G4. Then it was fine for the first 2-3 days then one day the home screen just got stuck and it wouldn't register any swipe at all. Rebooted the phone then it was fine but it happened several other times afterwards. That's very frustrating in my opinion. If you don't have that issue then its good cause the G4 is a solid device, but for me that issue plus the device tends to get quite warm sometimes and stutters a little bit so I decided to go back to the S6 which did not give me a single issue after owning it for a month.
[G4 General] Th3Bill:
Quite possible. What carrier are you on? Not sure if that matters like the OTAs do. I'm on T-Mobile.

Do you have missed taps?

---------- Post added at 11:46 AM ---------- Previous post was at 11:44 AM ----------

I rather expected that it would take a little bit of patience when I got it. I've never owned a device this early in it's "lifetime". At least LG seems to be really pushing to get everything ironed out as quick as possible.
[G4 General] chriskwarren:
Bell Mobility Canada (H812, build H81210c). I will update my sig asap...xda noob error :)

I have missing taps too, mostly evident using the keyboard (Swiftkey). The multitouch testing app shows no missing taps. I decided to use LGs keyboard about an hour or so ago and it seems better, but I'm not sure yet. But no keyboard service update here.
[G4 General] BrokenWall:
I haven't had any improvement. I used the Google Messenger as well as EvolveSMS on my G4 and my Moto X (2014) and notice that the G4 lags when typing long responses, I also have more mistyped words on my G4 than with the Moto X. I am tempted to go back to my Moto X until either the G4 gets rooted and romed or the new Moto X comes out.

Problem is that the G4 has such better battery life, nice screen, better camera that I haven't switched back yet.

Seriously use a texting app and start typing a long message that would usually be in 2-3 sms and notice how the phone lags more the longer the message is
[G4 General] Culex316:
I totally understand your frustration. I would also sell my device in a flash if that were to happen to me too.

I have the International H815 (not H815T), so I am hoping the same doesn't happen to me. I will report back in a week to let you and everyone else in this thread how it's working out for me.
[G4 General] Th3Bill:
No problemo on the sig. I see you're a fellow "phone whore" like me, changing devices like underwear. :)

I used swiftkey for about an hour...couldn't get used to it's location of special keys LOL.

LG keyboard was very wonky when it came to the long-press for special characters....took like 5 second long-press. Update cleared that up without so much as a reboot.

Maybe you have apps set to auto-update on the LG update app? I know I usually turn that feature off on my phones for all "app stores" as I like to read changelogs before choosing to take or not take the update :)
[G4 General] player911:
I dont see this App Update in my Verizon model. Can someone post the apk?
[G4 General] atsitalian:
I'm on the at&t version and don't see the update yet either. I disabled dual window and forced GPU rendering and it "seems" better but not sure if it's a placebo effect or it is actually better.
[G4 General] Th3Bill:
I forget where, but someone mentioned that they were able to search for it and found the update. I think it was in the thread about how much you like your G4.

I can try to pull the apk later from my PC. I'm not sure if device will let me pull the updated apk without root. It's going to be in /data/app if I am correct, and that's only accessible with root...at least on the phone it is.
[G4 General] jbdan:
Wow. I updated LG keyboard (said I needed to even though I don't use it) and rebooted. I feel like ALL my touchscreen issues are gone so far. Still testing and will post back if I feel otherwise. Who would'uh thunk...
[G4 General] WheresTrent:
Please do. Because this hasn't fixed my issues; definitely not in Pinball Arcade, and it seems like I still have problems tapping icons in Android. I also don't use the LG keyboard.
[G4 General] Kenishi99:
I just put the screen protector I had on all my earlier phones on the screen.

I never had problems with the other phones so far.

What I found out: When the screen is laying somewhere and you touch it it is unresponsive like hell.

When touching with two or more fingers it doesn't recognize it at all.

BUT when you touch the back with one finger or more while using the touchscreen there are no issues at all.

Why is that so?

Can you try this on your phones?
[G4 General] aygul12345:
Is it a hardware issue?

---------- Post added at 22:35 ---------- Previous post was at 22:34 ----------

How did you upgrade the lg keyboard?
[G4 General] jbdan:
So far I only have one touch screen issue and that is on the Google keyboard. All my other mis-taps and mis-swipes are gone. It also seems that some minor lag i used to have is gone. Seems snappier. Crossing my fingers

I did it through settings>about phone>update center>app updates. I own the T-Mobile version
[G4 General] thatITguy:
Mine misses touches pretty frequently (Verizon, VS986). At first, I thought it was due to the tempered glass screen protector. It continues to miss even after taking the screen protector off. I have had better response by switching to Nova Launcher and using SwiftKey but it still has issues.

It is very frustrating when trying to type responses and having to go back and correct several words due to missing characters. Playing games can also be hard because the quick taps aren't registered.
[G4 General] Snakecharmed:
After installing the LG Keyboard update, the screen seems to be performing much better. The double tap to wake has been perfect so far. When the screen was on, I don't recall any missed touches that weren't my own fault from tapping the wrong spot. I think I remember one missed keypress on the keyboard though, but I could have been mistaken. When you've gotten used to missed keypresses over the past couple of weeks, your expectations of reality get altered.

I don't know if this keyboard update fixes all the issues 100% because the missed taps seem to come from multiple possible causes, but it is notably better than it was for me before the update.

Also, I would say the biggest noticeable improvement is the elimination of lag when you long press a key on the keyboard to bring up alternate characters.
[G4 General] barondebxl:
I missed a lot of slicing on fruit ninja due to the screen not being responsive.
[G4 General] aznblade:
Mine did this only a few times where it gets stuck and it can't register my touch but funny thing that emails and updates goes through weirdly enough. Mine stopped doing it after I cleaned up my screens and removed the weather widget. After that works great. I have the H815 EU unlocked
[G4 General] frope01:
I tried all the "fixes" and nothing worked. I exchanged for a new unit which worked fine for two days. I'm now having the problem again.
[G4 General] ambervals6:
It is software issue. Some kernel update can easily fix it, just like it happened with 1+1.

Sent from my SM-G920T
[G4 General] aygul12345:
First the g3 had overheat issue and the g4 have unresponsive isseu
[G4 General] Svartsyn333:
I had this issue, too, but was able to fix it by installing SGS Touch Booster app from the Play Store and setting it to "optimized".
[G4 General] Kenishi99:
When you have the phone on the table without touching the back and test the Touchscreen with 6 fingers, does it work for you?

EDIT: Reason for asking - when you have a screen protector on the display it won't even recognize two fingers...
[G4 General] pugliatti2000:
Try using the G4 in the sun, a touch crazy.

Inviato dal mio LG-D802 utilizzando Tapatalk
[G4 General] liamR:
Trying to pinpoint the problem, so far it seems like there're 2 main features to it.

1. When the device is "sleeping" (Screen is off) it doesn't register some taps (I can find myself taping about 3-4 times for it to register the taps properly).

2. When the device under heavy/long time use at some point it starts to miss finger taps and slides.

This indeed looks like a software issue (kernel).
[G4 General] BoldCasual:
Mine doesn't do pinch-to-zoom anymore. As in, this gesture doesn't work at all, in any app, at all the time, making maps really unusable. It's as if its been disabled. H815. Misses taps every now and then, too + general laggyness.

Edit: tried the touch test through service menu, and it doesn't recognize more than 1 finger on the screen at a time (i.e. no multitouch). Very disappointed.
[G4 General] liamR:
Are you saying it becomes worse with time ? Did you try to hardreset the phone ?
[G4 General] rsbenedict:
Can't find that touch test in the T-Mobile Version. I can get to the hidden menu, but can't find the touch test.
[G4 General] sharpehenry:
Force GPU rendering under the development might be helpful. It did on me. But I think the phone should work the way it should without us messing around.
[G4 General] frope01:
Has it had a noticeable effect on your battery life?
[G4 General] shook187:
My battery life has actually gotten better... Force rendering has completely transformed my phone overall... I was on the verge of returning my G4 till I decided to try it out...now i'm official keeping it.
[G4 General] brapicoco:
I'm torn between the s6 edge and g4. Planning to get the g4 because of the larger screen but i've been monitoring this thread and it seems that the touch screen issue is still not fixed even after LG pushed the update..

Any progress so far? Or is this really a hardware issue? Thank you.
[G4 General] a_ride_4_ever:
I started noticing it after turning smart locks on. Its especially noticable on waking up. Turning off power saving seems to reduce the error rate but still happens on ocasion.
[G4 General] Snakecharmed:
Experienced some failed double taps to wake since my last update. LG Keyboard update is not a complete fix. I'll be trying the Force GPU rendering option in Developer settings next.
[G4 General] brapicoco:
Is this a hardware problem that LG is masking through a software update? Much like my z1 before..
[G4 General] Kenishi99:
That's exactly what I had after using a display protector on my phone.

Do you use a display protection?

Do you use a phone case? Bumper? Or a different back?

Could you test something?

Do the test on a table and then while holding the phone in your hands.

Does it better recognise your finger when you hold the phone in your hands? While touching the back with your fingers?

That's what I found out.
[G4 General] Culex316:
I have now owned the phone for about three days and I still do not experience any touch issues. I left the screen protector that the phone came with on. Only minor issue is double tap to wake occasionally not registering but it is a minor issue at best
