That's true, it's weird, when it is charging the problem of touchscreen is gone, maybe not gone but less annoying.
[G4 General] thatITguy:
The WiFi issues was having was that it would just stop working. I would have to disable WiFi and then enable it again. Once I did that, it worked fine for a few days.

It has been a little over 24 hours since I received my G4 back from LG. The touch issue seems to have be resolved but I will hold off deciding it is completely fixed until a couple more days of use.
[G4 General] rsbenedict:
Since T-Mo got the H81110n update, my touch screen issues have nearly all gone away. I'm also able to use knock code while charging which I was never able to do before.
[G4 General] shag_on_e:
Is there a detailed changelog anywhere for the update you took? I'm wondering if the changes can be duplicated for other root users that haven't received the update so they can just modify the system to squash this freaking touch screen bug.
[G4 General] rsbenedict:
I haven't looked. I just noticed an update and updated. Didn't even know what it was supposed to fix or add. Usually I look into these things before upgrading, but last week was so busy, that I didn't have any time.

---------- Post added at 10:26 AM ---------- Previous post was at 10:24 AM ----------

Just did a cursory search and there doesn't seem to be a changelog, but it is said to fix the stagefright issue among other things as it was 350mb.

Does LG official response for this issue or they didn't noticed? if only LCD touh sreen have some probelm they manufacture should

I received the 10h update from Rogers and now my phone is fine. I have a clear plastic protector.
[G4 General] Jonathan-H:
I'm having touchscreen issues on mine with or without screen protector.

Sometimes icons indicate I have pressed them but the app doesn't load, other times the screen simply doesn't register i've pressed the screen.

Knock code to turn the screen on works around 50% of the time.

Same. Touchscreen works perfect except for double tap to wake. So annoying. I don't understand how lg isn't addressing this issue, especially seeing as the power button is on the back and users rely on dt2w to work flawlessly.

LG G4 Recall ?
[G4 General] DoKaTSuYa:
With V10C I got no touch screen problem, since V10D I have so f****** annoying problem.

I had problem with V10B when I just got the phone, I updated to V10C works great, but V10D the problem came back in different way, so it's software !
[G4 General] frope01:
I'd say it's software too. I get those issues every few weeks. After factory reset it works great again...for a few weeks, until I must reset again. I shouldn't have to keep resetting on a monthly basis.

[G4 General] dork997:
I can confirm this V10C has fixed issue for me i am not updating further i have LG-H815 "suffix" NLD carrier free version Running v10c-eur-xx Can anyone please give me a link to this specific firmware so i can download its kdz and save it for future use incase i accidentally update it.
[G4 General] Kemby13:
For anyone having touchscreen issues, there is a simple fix:

system settings > accessibility > motor & cognition > touch feedback time > set it to medium or long

(note: this is for H815 international model as well as most others,

but some models will have "dexterity" instead of "motor & cognition")

I don't garantee this will help with all your touch screen problems,

but many people reported a lot less issues after tuning this option...

FYI, i have a Nillkin tempered glass (0.3mm) on top of my screen and

don't experience any issues whatsoever...
[G4 General] dongsa:
New to this thread.

It's highly likely it's software.

One good example of this is the Nexus 7 FHD 2013.

It was really unresponsive, to the point where I would not use it.

People started tearing into them and saying it was physical, reseat the cable, etc., and said it worked.

They lied.

I never touched mine, and once updates started rolling out, and 4.4.4 and 5.0 hit, it was like a new machine all together.

I just received an F-500L engineering sample LG G4, and it works great, still has the packaging plastic on the screen, I'll peel it off eventually and get tempered glass or a proper screen protector.

Unit shipped with Android 5.1 build LMY47D, software version F500Lx10d_us.

I'm pretty sure this is the latest and greatest until 6.0 comes out.
[G4 General] Resync:
i think its when the phone is idle with screen off, it sometimes misses touches.

nothing to dramatic here...

probably will be different with android 6

I sent my phone to LG for a warranty fix & got it back today. I can say it works so much better than before. According to the included sheet, they replaced the touch chipset.
[G4 General] frope01:
My first two phones had the issue. I got the first on release day and the second within two weeks of that. The second phone died last week and was replaced by warranty exchange. The new phone is about a week old and smooth as silk so far. I'm back in love with my G4 and no longer looking for a new phone.

Did the latest update not fix your touch issue? I haven't upgraded yet in hopes that our bootloader will be unlocked.
[G4 General] frope01:
My issue stopped while I was using my second phone. It must have been one of the updates I received in the last couple months. I had to reset every couple weeks then it would come back. The last time it just didn't come back. I'm on AT&T by the way.

[G4 General] thorcyar:
hello, that's exactly what I have : after some (long) sleep, phone will hardly wake with touch.

NOTA : phone will not wake with volume down photo shortcut either, so it's not touch related but most probably the sensors (physical or locical) are "too asleep to register their use"

You can unlock your bootloader from lg website. I didn't unlock mine (h811). I just flashed a rooted stock image then flashed twrp. Now running blisspop.

Could someone tell me if these touchscreen isues include phantom touches? My last phone had phantom touches and it seems it was because of my hands.
[G4 General] melvinchng:
Not sure have anyone mentioned this before, I do not have any problem with my knock on when I first purchased my LG G4. I found out that my screen does not really respond to my knock on after I installed tempered glass screen protector. I solved my issue my updating the proximity sensor (Boot into MiniOS). Apparently, the tempered glass that I have covers the sensor and causing all sort of issues. If you have tempered glass / plastic protector, check whether your material covers the sensors (on the right next to the camera)
[G4 General] redeyss:
Removing the glass screen protector on my G4 solved the touchscreen issues I was having. It did have to proximity sensor cutout. I'm on at&t 81010o firmware and debloated if that makes any difference.
[G4 General] player911:
The G4s had something going on at first. The later updates include fixes. I dont think it is a touchscreen problem as a background service hogging resources. If you enable touches in developer options, the screen was constantly making contact even though the phone wasn't getting it. Verizon got 13A with the fix and its night and day.
[G4 General] fiyawerx:
13B fixed it for me on VZW. It's 100% better - i used to not be able to swype two words in a row, now I don't get any misses.

Do you mean that we can still install twrp and flash a custom rom even with a locked bootloader? What is the version of your g4?
[G4 General] dadrumgod:
Uh yea a lil clarification on this please lol I thought someone bad to bump a twrp img. to trick the LG bootloader into thinking its an official lg recovery with a locked boot loader.. Is it an official twrp? And I bet somehow it still won't work on a Verizon model I'm not that lucky
[G4 General] pipeysh:
serial number

there are those who thinks those phones whose serial number starts with 509 and below are the ones with problems.

my g4 has a serial starting with 510, no problems with touch, got a tempered glass installed.

i think you might want to check on this
[G4 General] bigz1981:
Actually I have seen more development for the h815 than the h811...I see a lot of posts from h811 devs who port roms that have been created for the h815. Also I just remembered that I also did OEM unlock before doing anything on my phone. Easy enough to do:

-Settings

-Phone Info

-Software

-Keep tapping on the build number until you get the message that the phone has been OEM unlocked.

http://xdaforums.com/showthread.php?t=3190768

I haven't looked in verizon forums so you will have to browse them to see what options you have for rooting and twrp manager has the h815 version of twrp in its database.

If you don't already have twrp, download it from the twrp thread & flash it using flashify.
[G4 General] dadrumgod:
Nah unfortunately, unless I've somehow missed a big party, the Verizon model still has no twrp or especially a bootloader unlock, and I seriously doubt it ever will knowing the way Verizon is is or has been with some models for no apparent reason. But if it does get the same kind of love as your models have gotten sure it would at least be a good while until it happens. It will take some developers putting a lot of extra time into hacking that thing because I don't see Verizon letting up or LG but hopefully I'm wrong
[G4 General] drumbeater79:
Pressing the build number several times opens the developer options only, and not to unlock bootloader.

Can twrp be installed on locked bootloader?
[G4 General] dadrumgod:
Wait...what?? Did somebody actually tell you that's how you can unlock your bootloader?? Lol if so that was just plain damn mean and teasing you. And no you can't flash twrp with a locked bootloader unless someone bumps a twrp which would trick the LG bootloader into thinking its an LG recovery.. if you go and flash it with a lot bootloader you're going to end up in a boot loop that is not very fun to get out of
[G4 General] drumbeater79:
Read post #723.
[G4 General] dadrumgod:
I know man my bad I was being a smart-ass.. I was trying to relay before that is two different models basically
[G4 General] bigz1981:
Sorry. I said OEM unlock which is basically unlocking the dev options. Didn't mean to imply that it was the same as unlocking the bootloader. However, on the h811, I never officially unlocked my bootloader. I flashed the rooted stock system img on my phone then the twrp restore image using the posts and no issues on my end.

---------- Post added at 05:36 PM ---------- Previous post was at 05:31 PM ----------

I had been playing with custom roms at one point, but switched it back to full stock to send back to lg for repair on the touch issues. When I did that I went to the 10N base. It's harder to get twrp on the 10N base because you have to use flashify, which doesn't always work. i ended hacing to flash twrp for the h815 then flash the h811 twrp zip using twrp...wasn't ideal but it worked.
[G4 General] yakkity0:
I frequently see this problem on Sprint, but it seems to occur mostly when the network changes - when I enter a wifi zone, when I enter a subway (dead zone), or just if it falls between LTE and 3G. I'm Rooted on UltraPop-1.42.
[G4 General] heartagramm:
Here is one H815 international version with the stock 5.1 rom in it. I too have touch screen unresponsiveness as a problem with my device, I've owned the device for just over a week now, previously have had Samsung devices, latest was Note 3. None of them had _any_ issues regarding the responsiveness of the screen, and so far I've thought that this is just a feature of an LG device. But alas, it seems it just seems that it is the LG G4 that IS the problem.

- double tap wake doesn't register easily, you have to double tap several times

- while typing, you get really bad lag and miss letters if you write too fast with the device. This is ridiculous as it's a 2015 device, and was (still is?) the flagship of LG. Again, I had no issues with Samsung devices that I've had (i9000, i91000, i9300, GT-N7100, SM-N9005).

- I also did the factory screen test that pops up with the specific code, and on the edges the touch recognition is very bad. You have to glide your finger very slow and careful on the edge and most likely even then the screen won't recognize the touch.

This makes the device a pain to use. Wish I had not fallen through ice 2 weeks ago, I would have my Note 3 still functioning. :s
[G4 General] s0ulreaver:
My G4 LGH812 was manufactured in December 2015, hardware revision is v1.0 and I had a pretty bad experience with the touch screen missing touches.

So bad that I was actually thinking of returning it just for this reason only.

I had 2 firmware updates installed so far, one OTA, the last one was the update to MM.

The touchscreen response has improved with both updates so now, with MM, I have no more issues with the touchscreen.

I saw someone advising to enable 'Show touches' in 'Developer Options' to alleviate the touchscreen problem and so I did.

Does it help? Can't say. Try it and see for yourself if it makes any difference.
[G4 General] bigz1981:

Hi guys!

I've bought an G4 this year april and sadly ive got some touch screen issues.. Some weeks ago i've faced that my touch screen is not working all the time..: eg: when some1 called me the screen was unresponsive etc. 2 Days ago @ night i just charged my phone and next day morning the touch screen is dead. Its not responding to any touch, only the phisycal buttons are working. I've tryed a factory reset, but the same error occurs for me.
[G4 General] danaff37:
I find that my screen sensitivity improved dramatically, and all my issues with missed taps and taps instead of scrolls went away, after doing the motion sensor calibration under settings. I'm thinking that even if it doesn't do screen calibration, values are still written when writing the motion results, and that's what happened. But it's dramatically different now. I'm purposely using extremely light touches and it's working fantastic, scrolling, swiping, and tapping.
[G4 General] smw6180:

[G4 General] jamesjjj:
i have missing touch here on G4, just got it yesterday. A bit disspointed

The issue is exaggerated when I start using stylus, which work perfect on my iphone 6 and GS4, but on G4 only 30% to 50% of the time it get registered.

tried nova, still same issue, I open up google map and try move the map around with stylus but a swipe is not continuous so instead of moving the map around, i zoom/shrink the map instead

[G4 General] tripex2k:
I tested it with the QuickNote and ArtFlow apps, 100 of 100 taps registered. (Counting them all was not funny.). I use the Google Input, Nova Launcher and did the Motion Sensor Test in the service menu.

I only found 1 issue so far and that is when you hold to select an item in the gallery app, the circle that indicates the state is bit weired, it enlarges und goes back, enlarges and goes back, as if I do not have enough pressure on that point.

The missed tapping issue was with the original UI and the original LG keyboard, after switching to my normal tools of the trade, everything seems fine so far.

I think the slightly curved screen can be the weak point for a hardware issue, but at the moment it looks more like a softwareissue that can be corrected.
[G4 General] audscott:
Touchscreen, heal thyself....

I was having the touchscreen problems on my H811 (T-MO), naked screen until the T-MO update, then they went away. The most noticeable was the "P" while typing. I'd have to punch 3 or 4 times, hitting the left side of the "P" key. Now suddenly the problem is gone.....puff!!! gone. Battery performance improved, at least the first day going from average of 4 hrs sot to (yesterday) 6.5 hrs.

Maybe T-MO took the bull by the horns and made some badly needed enhancements.
[G4 General] emiratesson:
I have the same issue with my G4 Dual Sim Model H818P. I contacted LG regarding the issue and gave them videos of a screen recording of mine showing the touch screen issues. They asked me to use my warranty and take the phone back to the retailer. Of course, the retailer asked me to givd the phone for about three to four days, and I refused. I will wait till LG decides whether it is a software or a hardware issue. Aa software will be fixed with an update, of course if it was a hardware issue LG will have to deal with it. The strange part is that right now, I do not have the touch issue at all! It is 22:00 here so when it hits midnight the phone goes crazy! This phone is HAUNTED! :D
[G4 General] Semantics:
I loved my G4 but it went back to T-Mobile. Trying to type texts on the thing was maddening, so many unregistered touches, I wanted to punch the phone right in the face. I'll be sitting and waiting I guess until either they fix this, or something new comes out over the summer. Very disappointing because I loved the G4, except for the omission of smart screen which really pissed me off too. :)
[G4 General] aygul12345:
Im really want to know if this a software issue or a hardware issue. That being said, i really hole that they gonna fix this. It seems the GUI of LG seems heavy on the phone. Hope they gonna fix this.

What About if you put the extra settings off? Like dual window mode? Do you have still this issue?
[G4 General] Kristen21:
I'm going to say yes, it still happens. I've tried everything I can without a factory reset. Which I really would like to avoid lol I am still considering switching to nexus 6.

I absolutely love the LG camera though that and the nexus 5.2 is around the corner is keeping me on the fence.

[G4 General] zkyevolved:
I had a Nokia 1520 with this same issues. It was called phantom taps. While swiping or tapping sometimes it would register, other times no. Other times it would tap while swiping or the other way around. It was a 100% hardware issue that most people could remedy by reseating the screen into the body by pressing the top and bottom of the screen into the body. Strange, right? Nokia released a few updates to fix it but since it was hardware related, it could never be 100% fixed.

Hopefully this isn't the case with the g4. I was about to exchange my note 4 for it before finding this thread...
[G4 General] liamR:
I just read about the Nokia 1520 problem, I think that the cause is not the same but the affect could be. Maybe the glass isn't glued to the digitizer as it should and that why some experience the problem and others aren't, if it was software issue then everyone were affected.

This information is very disappointing. I'm also afraid that LG will try to hide it like all other brands do. I guess the only way to avoid it is to wait for a fixed batch (probably a few months).
[G4 General] emiratesson:
Well I am afraid as well. It happenes to me with a previous device. If this maybe the case then we will be living a disappointment.

LG said nothing about it at all!
[G4 General] Sher The Love:
I've been messing around with this app a bit. It seems that slow swipes from the side of my phone dont register at all. I can slowly move my finger from either edge of the screen and it won't pick my finger up till the middle of the screen.

I've also noticed that swiping up with my thumb (the motion of moving a web page up) there are times it switches from blue to red. What I gather from that is for a split second it reads two touches and then the "first" touch disappears, leaving the "second" touch. Not sure what that means, but it doesn't happen at all on my nexus 6. And since comparing them more, I've really started to notice the unresponsiveness of the G4 screen.

Since this phone has a removable back cover, it an easy fix.

Yes, I took the phone apart.

I took a look at the screen, and there were a few minor mistakes in the build of it. I brazed those and it worked perfectly fine afterwards. I do not recommend trying it yourself, it might break.
