Crazy Touch Screen Not Responding Bugs with my G3

So most of us know about the System UI crash when using Chromecast, but this is even stranger. [Edit: an OTA update fixed this.] Some times, when I wake my phone up at the lockscreen or at times in the middle of a call - the touch screen stops responding. I can press and/or hold the volume buttons and there is a response on screen but I can not interact with the phone at that point. I can't continue to do battery pulls everytime. This is crazy. I'm on stock software. No crazy mods or anything. I've done a reset in the past and flashed the stock package again but this still happens every few hours. Only happens when the screen just wakes up...
Edit: This is a confirmed fix for me.
If you face the same issue, try:
open dialer
press 3845#* INSERT THREE DIGETS OF YOUR MODEL NUMBER THE PRESS #, for example, I am the F400K, so 3845#*400#
Hardware Device Test > Touch
update touch firmware
touch firmware version
wait 10 sec
reboot

I would say there is a misbehaving app causing the phone to lag in wake (that is all the unresponsiveness will be, extreme lag).

@Lennyuk - tried for over 30minutes after leaving it alone, I doubt it's a delay... Battery pulls work, but that's not the point.

That was not his point.....to Find the app that is causing it go one by one uninstalling until you find it.... Something probably to do with app and the screen

Totally agree with @Epix4G on this one. I am assuming you had a korean variant? The SK Telecom stock image is pretty ugly. Took me 3 debloat attempts before I had it behaving the way I wanted it to, but before I debloated, I had some lag issues (SK Telecom... grrrhhh).
Historically, Korean carriers (much like AT&T and Verizon) love putting useless junk on the phones for "productivity" but really they are there to charge Korean users more for other services, etc.
If you haven't done so, I would root and debloat, and see how big of a difference it makes (absolutely amazing performance after debloating on my F400S).

^^^^ - Will take that into consideration.
This may be a possible fix for now, can't yet confirm
open dialer
press 3845#* INSERT THREE DIGETS OF YOUR MODEL NUMBER THE PRESS #, for example, I am the F400K, so 3845#*400#
Hardware Device Test > Touch
update touch firmware
touch firmware version
wait 10 sec
reboot
It may or may not help
EDIT: It's been a few weeks and I haven't had this issue again. Usually every 4-6 hours it used to happen after powering on the screen, but so far so good.

Tried that with 855 version, it's not working. This is REALLY depressing as i just got a new phone and from day one i'm having this problem. I just can't believe LG screwed up like this, and there's no mention of this anywhere online other than this XDA thread. I hope i don't have to root and install custom rom as this really defeats the purpose of the phone.

@deedscreen
I'm having exactly the same problem on an 850 and tried your firmware method. The version number of the firmware did not change after reboot.
ic_fw_version info
SYnaptics 5.5
PanelType 1
version: v1.22
IC_product_id[PLG313]
Touch IC : s3528(family_id = 1, fw_rev = 1)
What version is your firmware? Also, did you find out about the fix from somewhere?

I have the F400K, but just got a US T-Mobile edition, (I'll eventually switch my signature). I would honestly suggest waiting for an OTA update. Call LG so they can document this. If that touchscreen update method doesn't work, I'm not sure what to do. I found the method somewhere online, I don't recall where exactly. If someone can figure out how to side load the touch screen firmware from a working Korean model to others, that would be great. For now, keep calling LG. It won't do much at first, but at least they'll have reports of this issue.
I have (RAW) touch screen firmware version: 30 05 51 96

Same problem, but not only on lock screen
Since 5 days I have my G3 (855 Modell). I was happy the first two days, then I discovered the problem, that the device is always unlocking itself, when in my front pocket. It's because of the Knock on feature. I deactivated this now.
But since yesterday i have the same issue: three times, i was unable to unlock my phone. The touchscreen simply did not respond. I had to remove battery. Today, I read this post and tried the firmware update of the touch, but I have the impression it did not change something in the version.
After this, today I had again once time the non responding touch while unlocking and shortly after, I had the issue after ending a phone call! The touch did no longer respond and had to remove the battery again!
I hope this is not a hardware issue, otherwise I will hurry up to the seller to exchange the phone, because its only 5 days old.

This is happening when the screen is on right? Or is the screen turning off and then not turning I again?

You need to keep Knock feature on, someone already said this. That's why your screen is freezing.

Upps, yes, I just read this message now. To late: I was in the shop now and got mine exchanged. Anyway, that issue with the knock on feature should be solved also by LG: it's not acceptable, that the phone is always unlocking in my pocket.But then I wait with deactivating knock on for the moment.
So bad: such a good phone and such an annoying bug

I sold mine after a few days, i was sick with it. I disabled the knock feature through the hidden menu only to have the screen freeze every day. What, i can't use the phone the way i like? I have to face the screen outwards in my pocket and risk damaging it? Screw that...
That, plus the overheating and horrible build quality (back got scratched in my pocket) was a deal breaker for me...

Yes, indeed i also think about it. I got an official statement from support, regarding that the phone is unlocking all the time by itself in my pocket. They told me stuff like:
- this is a normal behaviour and can happen (!!)
- don't put your phone in the front pocket
- use the quick circle case to prevent...
- disable knock on (which is at least not possible over a standard setting, but only via the hidden menu).
I wrote back:
- that for me, this is not a normal behaviour
- that 90% of male users are wearing the phone in the front pocket
- that I don't like to buy a case only to prevent a bug of a premium telephone and
- finally, that they please could tell me, where and how to disable knock on
I am curious about their answer...

Good luck with that, disabling it through the settings doesn't change anything and they probably won't have a fix for months. They'll probably fix it though Android L update which will sadly come 6 months from official release at least.
Next time i purchase an Android phone i'm going with Nexus line...

So what happened? How is it doing now?

Hey everyone, I just wanted to report my results of this touchscreen bug.
Well, I've only had my D851 for a week now. Of course I rooted it the same day I received it.
I had no touch issues until after restoring apps with Titanium Backup. I'd restore all user apps, then very few system app via XML. Since I just upgraded from a Galaxy S3 T999 I limited the system apps greatly. So much in fact that I only restored 1 system app......Media Storage 4.4.4 (Playlist). THAT WAS MY SCREEN KILLER!
The media scan on my D851 would render my screen unresponsive. I could only hold the power button and click power off or restart or whatever else was on that power menu. Then the phone would reboot after minutes of of a dead screen.
I flashed back to stock and reproduced the same issue. So now I've been running this device for 3 days without any screen lockups. I just have to rebuild my playlist again LOL.
I hope this helps someone here.

Knock
If you turn off the ability to wake by knocking the screen, it causes this issue where the screen locks. Turn it back on and the problem seems to go away.
I think LG really has to deal with this issue.

Hi guys, I have red a lot about this issue but I'm still confused with my LG G3 855.
First I realize problem with unlocking the phone using double click. Tried to upgrade touch software firmware using hidden menu and the screen became almost totally unresponsive. Tried to re-flash original 5.0 and 4.4.2, factory reset, battery removed, etc. but no luck.
I'm wonder if this is a software problem or became hardware. Should I consider replacing display or problem is in motherboard?
I really don't know what to do! Appreciate any comments or suggestions!!!
Thanks in advance!

screen far too sensitive?

New member here, first post.
I had my g4 several weeks ago (uk version). Great phone, however recently the screen seems far too sensitive. Sometimes apps or other features are activating on their own without me pressing on them.
I looked in the settings but havent found a way to resolve this. Can anyone offer any suggestions?

Just to clarify a bit more about my issue.
Its like the "floating touch" some phones have, where i can be an inch or two away from the screen but it still activates. More rarely, it seems as if it was activating by sensing light or movement. Strange. Is the g4 supposed to have this type of function?

That sounds like a problem. The G4 is actually known for lacking sensitivity and yours is doing the opposite. enable this settings to see if it is actually detecting ghost touches.
Settings, About Phone, Software Info and tap on 'Buidld number' 7 times. Then go back to settings and tap Developer options, enable 'Show Touches'
if the dots show without your intervention, then it's likely due to faulty touchscreen.
Anyways, do a factory reset and see if it helped.

Does reset solve the issue? , happening on mine right now. Appreciate your feedback. Thanks

Same here, on Imperium and Stock rom, I have the phone since 6 months and it is a really random issue... my bootloader is unlock so I don't know if I can send it to warranty.
For information I have enable the touch "tracing" in developper menu, and when the issue occurred it's getting me perfect vertical line from bottom to top screen, and open a lot of apps..

And from the sound of it... Yours pretty much ****ed, at least to my knowledge. Hardware screwed and no warranty. Just bought mine like 3 weeks ago, and hated it so much. So much hyped, but the experienced is so far ****ty at best.
I suspect mine hardware issue. This seems like it's gonna be the first, and the last LG for me. Even mine with warranty still intact. Blackberry used to give this feeling long ago with their ****ty storm. Now, LG and blackberry can share that same ****ed up grave.

As madgibbon indicates, I was on Accessibility / Motricity / Response time (my phone is in french so i'm not sure if it will be exactly like that on yours) and I have set to "Long".
Since that, the issue is no longer appear, I have also switch to rom V20F (Turkey) with still the same setting for accessibility, and I don't have the issue anymore.
I don't know if it is a hardware issue, my phone falls maybe 4 times but with a case and from a little height, no broken glass or something else.
This is all the things I tried before that ;
Using flipcover (QI charge and quick circle), I have tested the "normal" case but same issue
I had a glass protection, I have removed it and cleaned my screen, same issue
I have done lot of hard reset (i'm kind of full wipe addict), same issue
Only the solution of madgibbon works fortunately, thanks mate
I'm also a bit disappointed by this phone, it is great sure I mean fluid, great camera etc... but I have some little issue that ruin the experience unfortunately (this issue with touchscreen, i'm experiencing issue with my Chromecast too that i don't have with other phones, some heating, I don't find the battery usage so good since MM, can't relock bootloader since now). I don't blame LG because i'm using some of their products and I'm / was really satisfied with : Optimus 2x, Nexus 5, TV, Monitor, Sound Bar. Anyway, waiting for 2016's Nexus and I will see if I switch or not.

Screen problem after all, just picked my phone up from the place that I bought for under warranty fix, and they told me they did replace for a new screen, and all is looking fine and dandy for now. Hope it stay this way, finger crossed. 3 weeks purchased and already this problem. I doubt this thing will last.

GPS Problems Even on Stock

Love my Note 4 but lately I have had nothing but problems with this damn thing. GPS NEVER stays locked for me use navigation or even check the weather if I changed cities. Saw the fix on where you take the back of the phone off and adjust the GPS contacts, long story short the LCD screen broke on me. I see nothing but problems people have on this phone about the GPS and Samsung will not hold there end. Anyone else have the same issue with there GPS?
Sending phone out to get repaired tomorrow.
Nick

i was on cm13 for a few days and i had horrible gps on google maps. when i returned to stock, gps was fine again. if ur having gps problem even on stock it may be a hardware issue.

If you have time, file an Android bug report: h t t p s://source.android.com/source/report-bugs.html
I have the same problem with stock ROM. I have also had the problem on 3 other completely different Android phones from different manufacturers - also running either with or without the stock ROM - mostly on Lollipop. This is probably not a hardware issue as another member has suggested, but a bug. I seriously doubt that the 4 different phones I've experienced this with all have hardware faults. If you file on that website, I'll join you. You are not alone.

Sounds like you solved the problem with a new phone. If the problem ever arises with the new phone you may be interested in my post in http://forum.xda-developers.com/note-4/general/gps-close-to-unusable-t2948602/post67864418 (see post #339). I was able to fix my phone by partially disassembling it and removing corrosion on various contacts.

!! 7 attempts at swiping up !

Maybe it's just the screen protector, I know I've read some stuff about the screen protector and people rooting and flashing something, but I swear this thing doesn't respond to my touch. I'm on Android p DP 2 and just factory reset it to see if it helps with some app bugs. Just swiped up 7 times before it went up so I could type my pin in, this has been an issue with this particular device.

I have noticed this sometimes as well on DP2. I have a fingerprint setup but my phone is usually lying on my desk so i swipe up and enter the pattern. Sometimes it just refuses to swipe up and stay there.. its sort of bounces back down. I have to pick up the phone and use the fingerprint scanner.

They lock screen swipe issue was fixed for me recently on a security update but on dp2 sometimes it's worst then it ever was before the fix.

Just tap the lock, no need to swipe

Ah never noticed that. If you have the fingerprint enabled, tap the fingerprint icon.

Are they not allowed to test and provide feedback? Why does it bother you?
Anyways, to be fair, I've been experiencing this issue off and on ever since I purchased the phone. And no, I'm not running beta firmware.

Why does it bother you if I comment?
If you're running a version of Android that hasn't been officially released yet then there is always going to be issues. That's pretty obvious frankly.

The lockscreen swiping is definitely an issue with the Pixel 2 XL. I always had this issue on Oreo but on P DP2 it's gone. It's interesting how it's the opposite for others in this thread.

Even on Oreo, it's hit or miss.
Swiping away notifications almost always takes at least 2-3 tries.
Super annoying for a phone this expensive.

Yeah the swipe up issue definitely does happen once in a while for me but it's not often or consistent. Now that I know the tap the fingerprint/lock does the same thing, I just do that.

No issues here. If i'm looking for perfection ill go purchase one of those $25,000 phones and even then you'll find something wrong.

Lock Screen unlocking problem guys, screen is unresponsive for 3 seconds.

after each lock when i turn the screen on with double tap or power button screen is unresponsive for good 3 seconds. This started happening after the latest camera fix update. When if i use aod and use the fingerprint through the aod this doesnt happen. tried reboot and factory reset with fresh install (no backups) tried safe mode. Same thing happens.
S20 plus exynos.

Yup happening to me too (s20+ exynos). For me the time of unresponsiveness is around 1-2 seconds. Happened after the latest update.

Yes, have been facing the same issue since "ATCH" update.

Yeah has been driving me nuts. Same problem.

I'm surprised this isn't gaining more traction? Can't be the only few experiencing this!?

Glad to see it's not only my device. Waiting for fix.

I have similar situation

I did this already and while it feels like fingerprint is faster, unfortunately this is a screen issue. You see if the screen is off and i put the finger in the correct spot it always scans my finger without any lag. The issue is occurs when -
a) I have unlocked the phone using above way, then the screen becomes unresponsive right after unlocking.
b) The screen is off and i either press the power button or double tap to wake, then the screen will be unresponsive and its during this time the fingerprint scanner doesn't scan (because the scanner doesn't know it needs to scan since the touch is unresponsive)
so TL;DR its not a FP scanner issue.

I am quiet sure Samsung is already addressing this issue for next update.
