I've been having a a bit of a strange bug with my GN...
When i unlock and open for instance messaging app to look at SMS's...i see the screen dim a lot and come back again. If i open up settings screen dims like an LCD panel with no backlight. If i click back, screen comes back again or if i lock and unlock screen, all is OK.
I've done some fiddling about and it only seems to happen on apps with white backgrounds i.e. messaging, gtalk, gmail etc. If i open dark background apps i.e. phone app, settings or gallery it doesnt happen.
But for all those other apps when i launch them, screen appears to flicker (dim) and come back again...messaging is the only one where it dims completely in settings.
Has anybody else noticed this?
And more wierdness...in the messaging settings menu, if i scroll to the bottom the brightness goes completely and then comes back again, and starts flickering a lot...
maybe i'll try turning off auto brightness and see if it still does it...
I've had a couple of customers come in already saying they always felt like the brightness was on notch to low sometimes or just very dim. Considered it user error, just got my nexus in the mail and after set up brightness just dropped randomly to almost nothing...
soooo guess we'll see
ah well still did it with auto brightness off
wonder if i've got a borked phone or if others do it and they just dont notice...
EDIT: if anybody's interested in seeing it i've just uploaded a vid here
And i know i still have the front screen cover on...havent wanted to take it off yet!
Restored stone to factory settings this morning and i've not installed anything else or changed any settings (other than turning off NFC, wifi and mobile data)...and it still does it.
Think i might have a defective handset then...annoying though, it's only 2 weeks old but the place i got it from states
Phones that are faulty out-of-box as determined by our warehouse can also be returned for an extended period of up to 7 days from date of delivery.

So if i can't get a replacement out of them, what are the odds of samsung replacing it for a new handset?
Hmm pretty sure it's hardware, set desktop picture to something quite bright/white and sure enough when i was scrolling through the 5 homescreens brightness was flickering from one to the next...
What are the odds of getting a replacement handset after 2 weeks? :|
I had this same issue when I got my phone. I had a yakjuwx build in my phone.
Ever since I flashed over to yakju I haven't experienced it.
You may want to check and see what you have.

Hi, thanks for the reply.
Mine is already running yakju from new :/ I might try re-flashing it tonight though just for the hell of it.
Is this not a bit weird that it happens only on bright/wight screens/backgrounds/apps? And that it's suddenly fine when you lock the screen...
If it was a laptop i'd be fitting a new panel to it but then i dont know what amoled's are like (especially combined with a light sensor)
Nope, still does it after a re-flash :/
Got a replacement handset now...
Like my first one, it was one of the early opened and re-sealed with samsung label handsets (and they hadnt put the battery door on properly, fingerprint on the SIM card slot!)
But anyways, waiting for the OTA update on this one
It's obviously running ITL41D and no OTA has come through yet whereas on my first handset it came through pretty much straight away.
Would the fact i've already had the OTA on one handset stop this coming through? :|
Hi,
I've noticed an issue recently with my SGS3 (I747M). The flicker that I am referring to is not the more common hardware overlays issue, but rather only occurs, or is noticeable, on a white background. What happens is the screen will flicker colors; it's not that the entire screen will display one color and change to another and another rapidly, but rather it seems random pixels on the screen will flicker in waves...almost a 'shimmering' effect. So far, it seems to happen not immediately after reboot, but later on as I use my device. I was hoping this was a software issue, but so far it seems to be more likely a hardware issue.
From googling, I have found that this issue is not limited to myself (http://www.howardforums.com/showthread.php/1772504-Samsung-Galaxy-S3-Praise-and-Problems), that being said, I couldn't find anyone else here on XDA that has this issue. Have any of you experienced it? and if so, what did you do? return under warranty perhaps?
Thanks in advance.

It might be a digitizer problem, digitizers are hard to replace but, I think zedomax has a way to change it.
Just go on galaxys3root.com-- this might help http://galaxys3root.com/galaxy-s3-root/how-to-replace-broken-lcd-screen-on-galaxy-s3/
thanks for the reply, but would a malfunctioning digitizer actually cause the screen to shimmer as it does? I would think it might be a digitizer problem if the screen wasn't recognizing my inputs properly, but I think this is a different issue which, to me, seems to be not related to the digitizer.
thanks though!
any other possible ideas/solutions?
I have had that issue. It would do the same thing and then lock up because I would try and hit the home button. The. It would do a full reboot. Weirdest thing I have ever had happen to a phone. I tried different than roms and stock and didn't do a dang thing. Returned it to att.

I suppose if it actually does get to that point where it renders the phone as unusable as in your case, I'll probably do the same...though since it's outside the 14 days I have with my provider (Rogers), I think I might have to go through with a warranty replacement through Samsung.
Thanks for the reply
update:
It seems it was either the ROM or Kernel that caused the issue (last few versions of task's AOKP). After flashing a different ROM (bacon version of Roger's JB), the issue seems to be resolved *knock on wood*.
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!
I've been able to replicate this issue on my G4 (815T Australian model) on a daily basis, just on the instagram app though.
I recorded a video of it. Slowmo part shows the issue
https://goo.gl/photos/F823e125PQckCPLp6
The screen seems confused and it just scrolls the other way even if my thumb wasn't touching the screen.
Factory data reset did not fix anything.
Are you able to replicate this LG G4 owners?
I don't use Instagram, so can't help with that app, sorry.
But if you go into Developer Options, and turn on "Show touch data", it might help add some more info to the discussion. It will show a trace on the screen of what the phone's touchscreen interpreted from your last tap/swipe.
It would presumably show a swipe up, and then back down, when you're getting these ghost touches that change the scroll direction. But perhaps it could also help show if swipes are interpreted the same way in other apps. It might help you learn a little more about what the phone is seeing, at least.
Thanks for the video and everything but why a new thread? Plenty of videos on the main thread.
Is another thread really necessary?

Might be, because this only happens with IG. I've got the exact same problem, only with IG and its very annoying.

You can try to change the touch feedback time from short to medium under settings/accessibility/motor & cogination. This will reduce the touch feedback time. Give it a try, and see if it gets better.

Well this problem is only related to the LG G4 and IG for me...I don't have any other touchscreen problems with this phone. So for me I guess this is not hardware related. During the day I just had 2 small "ghost touches", way better than before. Will see how it goes the next few days...
Edit :
after a view days, it looks like it didn't solve this issue. Today I notice the ghost touches were there again in IG
Force GPU rendening under Developer options somewhat helped.
The new v10f on my Australian G4 didn't fix the issue as well.
Any updates on this? I had same issue. N this is a replacement unit after 2.5 weeks of waiting
Just day one and this ghost touch come up.
I also have this problem
Did you solve the problem?
I am facing similar issue.between...i am not using ig.
I've had this issue as well (not just IG) and sent the phone back for servicing. It was sent back to me with a report showing that they'd done a few things but the problem is still there. I'd been thinking I'd send it back in once more and ask them to have another look. I'm getting ghost touches everywhere and quite a bit, it's very annoying.
Someone mentioned there was another, large thread about this issue but I can't seem to find it, can anyone point me to it?
Hi, I posted this in a new thread yesterday as I couldn't find anything. Never thought to search for 'ghost taps' duh.
Every now and then when just doing normal things on the my phone it totally freaks out and all by it self it suddenly starts to tap random parts of the desktop, slides the pages, opens apps, closes apps, goes into calculator and a bunch of buttons are pressed randomly. It's almost like someone has hacked my phone and is trolling me by just tapping randomly on the phone.
Just today when looking at Facebook it closed the app, scrolled down notifications, data was turned off and wifi turned on.
I thought it might have been my screeen protector, bit of moisture in it or something. Took that off and still does it. Took out the battery for a minute and still does it.
It happened a few months ago then nothing for ages and now it's started again this weekend.
Thought it might have been only when connected to data but has now done it when offline.
Any one got a solution? Does a custom rom fix?
I recently experienced really bad image retention issue with my LG G4 (and my wife's V10 but that is for another forum). It was so bad that even if I use any of those burn in fixer apps it just keeps coming back. It would go away when you turn it off but come right back within 5 minutes of using the phone.
In any case, I had it replaced for free since it is still under warranty. I'm worried now that it may eventually come back again because it seems to be common to the G4 (and the Quantum IPS screen phones)
My question is:
1. Has anyone else experienced image retention? Is it a common G4 issue? How can I avoid it?
2. For those that has experienced it and had their LCD replaced, did the issue ever come back?
Thanks!

Hi, i have the same problem but i found a very easy solution. All you have to do is install sfilter(or any other blue light filter, and no retention anymore, even if u keep it as low as 20 or 30%. I did the same, i keep my filter at 20% and no ghosting what so ever no matter how bright the screen is. And the second i turn it off, all hell breaks loose. I have an lg g4, but i am sure it will work on any ips display. Hope it helps ?

Hello, I am new here. I have same problem with the display on my LG G4 H818.
1. First instal from Gplay: " Galaxy Nexus Screen Diagnostic " . Now Test your screen with "repair custom" option. If leave 5 minutes on this screen test, images retention will disappear. This is first good sign.
2. Instal from Gplay: " Blue Light Filter ", for recognizing, icon is a 1/4 yellow moon ?in blue circle. Developer is Leap Fitness. This is my try. You can test another blue light filter and test.
3. Go to activate blue light filter from button, and set:
-Color temp to 3200k;
-intensity to 10, is enough and it works fine for me;
-screen Dim to 9%.
4. Optional, for better color contrast: Go in phone settings/ general tab/ accessibility/ vision / screen color adjustment / actiaye from button and move the cursor down a half centimeter. For me is enough this setup.
Hope this is helpful for all. Thanks
