How are you just going to leave the carrot dangling like that? Details please. Did you forget this is XDA where warranties essentially come to die?
[G4 General] WheresTrent:
I bought a new G4 at a T-Mobile store yesterday, and downloaded the update while setting it up. It feels faster, it seems to run a little cooler, and the battery seems to be better compared to the phone I got when I preordered. But I think I'm still having the occasional touch issue, and that's with Dual Window turned off.
[G4 General] daddymikey1975:
Mine is unresponsive as hell. Very frustrating.

Sprint version.
[G4 General] ambervals6:
Yes it does. Software issue just like the 1+1

[G4 General] liamR:
Another video demonstrating the issue (G4 on the left and G3 on the right) -

[G4 General] coolmaster121:
Seems like the sensitivity on the touch panel is either uneven or really low. Im a guy with pretty short fingernails, I can type on my Nexus 5 and LG G2 with the tip of my fingernail. But on the G4 there is no response. Also when typing using the native keyboard or even the Google keyboard there are def. missing touches. Keep in mind this is a second device I got from T-Mobile. One came from the online store the second one is from a retail store. Both have touch issues. For those hoping this is a software issue, if it was a software issue then everyone would be having this issue not just 60% of the XDA G4 user base. I'm going to figure out a sure way of reproducing the tap issue and will head over to a local T-Mobile store to get another replacement...
[G4 General] DRSdroid:
It seems like a software issue to me. I see it happen where my touches on the screen register slightly to the right of where they should be.

I clearly saw it happen in hungerquest so i rebooted the phone. Then it was fine. Then i downloaded a screen test app from the playstore. And everything tested fine. Then it happened again with the dreamcast emu and i ran the screen test app and it showed my touches accurately. When o switched back to the emu it was fine again. Seems like a software issue
[G4 General] coolmaster121:
Have you tried the fingernail test I did on my G4?
[G4 General] gsxcorey:
Just got a new one and mine is much better so far

---------- Post added at 12:32 AM ---------- Previous post was at 12:21 AM ----------

Nevermind. Same missed touches... Awesome
[G4 General] Semantics:
This is seriously disappointing!! My JUMP upgrade should be back on my account tomorrow and I was going to go to a T-Mo store to get a plastic back G4 this time, but if the screen is still doint that, I can't. I love the damned phone too. Very disappointed.
[G4 General] jairusz:
When I do a multi-touch test I register every input but when I use either the default or SwiftKey and actually type, I get missed and delayed inputs. It's rather off putting and I might have to get a refund before it's too late.
[G4 General] gsxcorey:
Same here. Keyboard issues... Really sucks. This new phone is even worse it seems
[G4 General] WheresTrent:
I returned my preorder phone via mail, so I went out yesterday and bought a plastic G4. Not as many missed touches, but it's still happening. Gonna spend a lot of time playing with it on the train to and from work the next few days, but if it keeps up, it's going back. I'm either going S6 or iPhone. :(
[G4 General] gsxcorey:
Google keyboard for me wotks much better than swiftkey it appears. I would recommend trying it
[G4 General] megamanfre:
So...Where are these problem issues on the screen? Where exactly did you look? Pics of the process? I've got my soldering iron warming up.
[G4 General] ruzkay:
Mine should arrive tomorrow. If I have this problem too I will be very disappointed. Since software, performance and display-wise my Nexus 4 is still top-notch. I can type like 55-60 wpm on stock keyboard...

I hope it will not be a downgrade!
[G4 General] DRSdroid:
Typing right now with fingernail without much trouble at all. Stock keyboard, stretched to be a bit more spacious. I purchased my unit this past wednesday and it already had the software update, or it did it right after boot without me noticing... Either way, I've noticed odd touch recognition intermittently, but when it happens its like the response of any touch registers 1/4" left from where its input. As of you are always hitting just to thr right of where you are aiming. But if i open recent apps or even open another app and switch back it corrects.
[G4 General] liamR:
I sent emails to some Tech news websites, here is the first reports (thank you Android Authority and GsmArena!) -

You're welcome to do the same :)
[G4 General] oranglewat:
So I had nooooo problem at all with my G4 for a whole week. Last Saturday I installed a tempered glass (It was a gadget show, and got it cheap on LG's booth) and sometimes, after it wakes from sleep, I can't seem to do the pulldown menu. Happens randomly and it happens often enough that it would be weird if for a whole week it didn't happened.

If I slide download slowly though, the pulldown usually pops out. Knock codes are harder on the my G4 than my old G3 though.
[G4 General] samecin:
AT&T G4

I am also having touchscreen problem from day one.

I really like this phone, so don't want to return it. Just Hoping for ROOT arrive ASAP.

I waiting for Dev to jump in and make Custom ROM that might solve this problem.
[G4 General] holzmann:
Bought my H811 from a TMO store in Washington DC on Saturday, 13 June. Update was installed in-store upon device setup.

1. Cannot access the "Device Test -> Service Menu – Manual Test -> Touch Draw Test" menu.

2. Downloaded the Multi Touch App instead.

3. No problems observed via the test.

4. No problems observed during real-world use over about 48 hours.

5. Phone so far is great!

I have a naked screen with a Tech21 Evo Tactical case.

---------- Post added at 01:09 PM ---------- Previous post was at 01:00 PM ----------

Doesn't work on my TMO H811. Neither does 3845*#Model#

The 277634#*# shortcut brings up a menu. Just not the one with the options being discussed.
[G4 General] gsxcorey:
Awesome job. I hope they fix it now. Wish i never turned my s5 in. So pissed.
[G4 General] StuMcBill:
The only time I have any issues is when the screen is off and I am trying to wake it or use knock code.
[G4 General] XTRoRDiNAiRE:
I get some unresponsiveness every now and then, it is annoying
[G4 General] rasel800:
Confirmed, poor touch sensitivity.
[G4 General] liamR:
You can try to test it with the Multitouch Test app that I posted [MENTION=225651]op[/MENTION] just watch the second video.
[G4 General] holzmann:
I did download that app from the video and tested it. No issues. Works great: one finger, two, three, pinch, zoom, swipe, etc. All registered.
[G4 General] Tomyk89:
I think people should start posting their purchase date for the phone as this may have already been fixed.

I purchased my LG G4 (verizon) on Friday 6/12. I have zero issues with touch (naked screen). Multitouch testing app shows no issues.

-Tom
[G4 General] rfarrah:
I am not having any issues with my touchscreen at all, but my fingernail doesn't do anything. I don't think it is supposed to....?
[G4 General] coolmaster121:
How did you arrive at the conclusion you don't have any touchscreen issues? Did you do the multi touch app test or did you use the UI of the phone?

How long ave you had the device?

Well I'm speaking from experience with LG G2 and Nexus 5. I can use the phone with my fingernail all day long.

Thanks for testing.
[G4 General] rfarrah:
I've had the phone since 6/4. No noticeable problems so I haven't bothered to test. In case it matters, I'm on Verizon.
[G4 General] coolmaster121:
Guess I am going to the Tmobile store to test their display units and replace mine. Because This is the most annoying thing about the G4 in my case.
[G4 General] Tikerz:
Unless you have weird alien fingernails, fingernails DO NOT work with capacitive touch screens as they are not conductors of electricity.
[G4 General] coolmaster121:
Here is an example, just filmed my G2

https://www.youtube.com/watch?v=8bQwaD_dzTA
[G4 General] Tikerz:
That's because you have short fingernails. The conductivity is actually coming from your finger being so close to the screen. Use your girlfriend's long fingernails and you'll see it won't work. ;)
[G4 General] coolmaster121:
The fact remains the same. I cant do the same type of thing on the G4.
[G4 General] megamanfre:
Got my new G4 today from verizon. The tech I spoke with said it was the first time she herself has had to do a replacement for the G4.

So far, I haven't had any issues with the touchscreen missing taps or swipes. I may actually turn off the touch display since I don't need to track it anymore. It actually feels like it should. Just wish I could adjust the sensitivity to be more like my a5.
[G4 General] yodan4:
i am waiting on my replacement from tmobile. I went into the store where I purchased the first one from and they tried to charge me a restock fee, for a warranty swap. I called their customer loyalty department, and they sent me a new one next day air. It is really frustrating when it doesn't work and it takes away the key knock feature.
[G4 General] arniman:
No problem hire, register every touch. Euro h815 unlocked
[G4 General] philbring:
Fixed by SGS Screen Booster app!

[G4 General] shook187:
Wow I just discovered my G4 is also having touch issues when I originally thought I didn't.. Even voted that I didn't.

I discovered if you swipe up from the Navi bar, that swipe goes undetected.

Why don't you guys try it using some of the touch test apps
[G4 General] liamR:
So far no comment from LG, a few of my friends exchanged their faulty G4 with a new one but the new ones having the same problem.

I tried this app and I tested it really good, I think that what you experiencing is a placebo effect.
[G4 General] bhtale:
Anyone with Korean models tried these kinds of tests?

Are Korean models having these multi touch issues?

Thank you
[G4 General] psygnosi:
Did test and no touch screen problems here. Using skinomi tech glass on screen and still no touch screen problems. HG-815 v10a-TWN-XX. Mine was purchased from ebay vendor never-msrp.
[G4 General] daddymikey1975:
Sprint version. Purchased in store 6/8. Missing like a V8 running on 5 cylinders. Naked screen. Have not swapped it yet.

It almost seems like the phone is "busy" when typing... It's weird and annoying as hell.
[G4 General] megamanfre:
Felt like you're updating 20 apps from the app store and the phone just didn't have the resources to handle touchscreen.
[G4 General] daddymikey1975:
Exactly!
[G4 General] megamanfre:
Try doing a system reset. It seems to work for some people, and for me it made it a little better. But it was still happening enough that I got a warranty replacement.
[G4 General] FMMFL:
I'm having the same issue on my tmo g4. I'm on my second replacement now and it's the same thing. My wife also has the same problem.

As much as I love this phone I may have to switch back to the s6.
[G4 General] daddymikey1975:
Spent a ton of time setting my phone up the way I want. I really don't feel like doing a factory reset. Lol

If it really annoys me, maybe I'll reset it this weekend. (yeah I'm kinda lazy Hahahaha)
[G4 General] mustbepbs:
I got fed up with the touchscreen issues and I have zero faith in LGs ability to get it fixed and pushed through Verizon in a timely fashion. I swapped my G4 for a GS6 and it's night and day. The GS6 is fast, fluid and the touch screen is on point. I don't regret the switch at all now. It's a shame because I really liked the G4 but I'm not putting the next 2 years of my smartphone life in LGs incapable hands.
[G4 General] Snakecharmed:
Some of my observations:

The screen felt more responsive immediately after the push update last week, but it's now back to where it was before the update

The responsiveness has seemingly also gotten worse after installing a screen protector

Hard presses seem to be more effective

Double tap to wake failed three times in a row for me yesterday after an extended idle, but once the phone is awake, it seems to work more reliably

There isn't a physical dead zone anywhere on my screen, which gives hope that it isn't a hardware issue

I think this is almost certainly a software issue at this point that results from lag. People seem to be having better results with Nova launcher, which is a positive sign. I've yet to switch to Nova, but I'm increasingly leaning in that direction. I hope that once root is achieved with this phone, our dev community can figure out this out because I trust them more than LG or the carriers in pushing out a timely fix for this problem.
[G4 General] FMMFL:
Before I decided to call Tmo and switch phones I decided to give LG a shot.

Their answer is for me to send the phone in for 'repair'. No loaner, no advanced exchange, just send them the phone.
[G4 General] gsxcorey:
Lg after calling wants me to send in my phone. Pretty dumb request when the person openly told me they don't know if it's hardware or software. Already got a new phone and same issue. Talk about frustrating.
[G4 General] ruzkay:
This thread had gotten me really scared but after getting my phone today I didn't notice any problems also with touch test I could fill out the whole area (I drew didn't care to tap for years). Seeing the poll I was thinking surely the ones who voted they have no problem just don't realize it? But I guess I'm one of those... luckily! Have unlocked H815 from Europe
[G4 General] Naaser:
Thanks god. No screen issues on my TMo
[G4 General] jamesjjj:
the double tap wake is so buggy on mine, so now I just "tap till you wake" consecutively, usually 4-6 taps lol
[G4 General] ruzkay:
Do the issues arrive later on or if I don't have them initially I'm fine?
[G4 General] coolmaster121:
I think I got the thing fixed by running the SGS touchScreen booster app from the Play Store. It seems to be way more sensitive using the Optimized option in the software.

https://goo.gl/oAsQRJ
[G4 General] rsbenedict:
I didn't have many issues with the screen except for knock code. I downloaded that app and tried it and it seems to have made knock code work so much better. I love knock code and prefer it to any other security method. I really appreciated it on my G3.
[G4 General] shook187:
Can someone run a touch test for me and swipe up between Navi buttons and see if your swipes are registering?
[G4 General] nexy33:
Shot LG a Support email here's my answer,

Good afternoon , I hope you are well.

Thank you for your query regarding your G4.

I hope this email gets to you safely and you have had a fantastic afternoon so far.

I am sorry to hear that you are still experiencing these issues.

This will indeed be caused by software, I would think that this issue will be resolved in a coming update.

As a question of curiosity , can you let me know whether this missed touches issue occurs on all applications and the home screen etc?

Looking forward to hearing back from you soon and I hope you have a lovely week.

You can reply to this email by clicking the more questions link below.

I mention on knockcode and the the screentest in the service menu as given by drippler plus a few apps it kept missing in.
[G4 General] WheresTrent:
"I would think that this issue will be resolved in a coming update."

No, I would think that this issue will be resolved in a coming update.

LG, you should be commenting on this. Android Authority wrote about the issue, it's here, it's on Reddit...rather than let people burned by the bad screen turn others away by telling them to get a different phone, tell us what you're doing to fix the problem and when.
[G4 General] jdugan83:
Trying to test my touchscreen....

Think I'm missing something here. I just received mine today VS986 version and tried the dialer with the appropriate number (277634#*#), nothing prompted, and when I called, it just informed it couldn't be completed.

Any suggestions?
[G4 General] megamanfre:
I believe verizon disabled that menu on our phones. Think they do this to all of their phones.
[G4 General] jaggrey:
I've realized I mostly see this issue not when I'm tapping but more when I'm swiping with SwiftKey. In the middle of a swipe it will skip, as if I lifted my finger off. If I then swipe slightly different it will work, so it doesn't seem to be that a particular area of the screen isn't responsive.
[G4 General] Ryslegit:
My tmo h811 once in awhile doesn't register the double tap, but it's not to the point where it is bothersome. Other than that my phone works perfectly fine.
[G4 General] SpinningHook:
On the VS986, the only issue that I have noticed is the occasional missed tap with the middle suggestion that Swiftkey offers. Other than that, I haven't had any problems in that regard, otherwise.
[G4 General] shook187:
Well I just got back from the T Mobile store and managed to exchange my G4. The original had minor issues but it was definitely missing some taps on the screen and often would register a swipe as a tap.

Replacement one seems better so far.
[G4 General] combsco:
Downloaded the app, works well up to six fingers then it gets spastic and drops touches. Other than that it is fine with .3 mm glass protection.
[G4 General] player911:
Just did this all this with 3 missed taps. They were lighter taps though. I think it is software myself, specifically surrounding the default homescreen launcher.
[G4 General] iflyimpilot:
You can add me to the list

I have the AT&T version (810) and noticed some issues with mine as well. I've given the factory reset a try and to my surprise it seems a little worse now.

**ONE THING I DID NOTICE**

For those having issues with missed taps when tapping to unlock screen, I noticed this on mine and did a little experiment. If the ambient light sensor toward the earpiece part of the phone is blocked thats when it seems to not register taps at all to turn the screen on.

Can whoever is willing to try please see if you can confirm this? For example just hover your other hand over where the front facing camera is so that it's blocking light from it (without touching the phone) then try double tapping the screen with the other hand to power it on and see if this happens to you too. If this is the case, we may be on to something. Not sure whether or not the ambient light sensor has any involvement in this but maybe it can help us determine whether or not it's a hardware of software issue.
[G4 General] natec003:
I just tried several times doing it exactly how you described with hand covering light sensor. I performed very light taps with no response. I then removed my hand and tapped again, the screen turned right on. I would guess it does this so the screen does not come on in the pocket. That would make the screen less likely to turn on in the dark also which is fairly obvious. Good catch. Fwiw I also think a lot of the missed touches are software related, and find it becomes worse when the device is "working harder" or there is Data being transfered.
[G4 General] nexy33:
This is when I first noticed it as well
[G4 General] MetalMan889:
Touch

I sent LG an email and this is what the response was:

Thank you for taking time to contact LG and we really appreciate your e-mail.

I hope everything is going well with you.

Thank you for bringing this concern up as we are not aware of the touch screen issue of the G4.

Your concern has already been raised to our Developers team and please expect an immediate positive response from them regarding this matter.

As a possible workaround, please consider performing a factory reset on your device and see if this would correct the issue that occurred. But by doing so, it will erase everything on your phone such as your contacts, pictures, music, applications and settings. Resetting the operating system will clear any bugs that have developed and restore the software to factory standard. Please back up your phone’s contents before performing that procedure.

From Home screen, tap APPS > SETTINGS > GENERAL tab (if applicable) > BACKUP & RESET > FACTORY DATA RESET > RESET PHONE.

Should you have any other questions, please feel free to contact us again via Email, Live Chat, or Phone by calling 800-243-0000.

I find this funny because I saw another post by someone that displayed a response from LG and it stated that they already knew about the problem and a software update would fix it. But in my response today they said they have no idea about it.

I have the sprint model of the LG G4 (LGLS991). I have noticed a few times when the touch screen does not respond. I didn't let it bother me until I saw all of the articles and posts about the issue. I started to test it and found that it does have a minor issue with some of the responsiveness. I love the phone other than this issue. I hope it can be resolved.
[G4 General] Draconian77:
Same problem here. LG G4 H815. Suddenly i couldn't wake up my phone via double tap. Tapping like a mad man. Wouldn't wake up. Now used the button on the back to wake up and double tapping is working again. What a fail!

Update: When you put 1 hand over the top of your phone it won't go on with double tapping. When you remove your hand it will go on. So it has something to do with the sensor on the top. It thinks it's still in your pocket for example.
[G4 General] bobloadmire:
Lol if course it doesn't wake when you cover the proximity sensor, the phone thinks its in your pocket so it won't wake.
[G4 General] drt054:
I have not noticed this on the Verizon variant.
[G4 General] liamR:
I returned my G4, I should get a new one from a new batch next week. I will report back...
[G4 General] Andrew025:
Has anyone exchanged a "non perfect" phone... Like you dropped it but only has a small mark on a corner?

I'm assuming if I go in complaining about touch issues they'll blame it on that even if the problem existed before the drop.
[G4 General] Shimpossible:
I've noticed the same problem and assumed it was the screen protector, or extra sensitive screen. Scrolling will sometimes open things instead of scroll, and other times taps are missed. After reading this thread I've rebooted the phone and things seem better, but I'll wait after a day of use to decide if that fixed it. This is a Sprint phone

Also, the MultiTouch test app registers 5 points just fine. For the 6th point it freaks out and it loses all the points. How many points are you expected to be able to track on the phone?
[G4 General] viberzdae:
My phone was laggy and touchscreen was unresponsive too. Especially when using the default browser. I changed to the UC browser.. Everything works fine now...

Guess this is the Temp fix for now until lg come out with updates to solve this issue....

Oh and I disable the dual window option too. Whole phone feels snappier now.
[G4 General] liamR:
Update:

According to Android Police LG US knows about the problem and they're looking into it.

http://www.androidpolice.com/2015/06/16/having-touchscreen-problems-with-your-lg-g4-lg-knows-and-theyre-looking-into-it/

Keep posting your experience and updates until they will issue a fix. :good:
[G4 General] Russosniap:
Try using Flesky Keyboard

Hi Guys,

Same problem here......I noticed that, in my case, the unresponsive to a swype is much more visible when the G4 is in charging! And if I reboot the phone the problem seem disappeared, but after a while it come out again, so I think, and hope it's just a software issue!

For a really good test, try to use Flesky Keyboard, this one, permit to type a "space" by swyping direct on the keyboard, but with the G4 you can do this 2 times on 10!

This is the way I discovered the issue! Let's Try!;)

I hope LG can resolve this with a software upgrade!

Thanks to All!

Bye!
[G4 General] iflyimpilot:
For those affected by the touchscreen issues, what's your wager? Software or hardware?
[G4 General] Snakecharmed:
It could be a fundamental hardware issue that is fixable by software. It appears that the OnePlus One had a similar issue. From what I've seen, software lag plays a role a well.
