Hi guys,
Anyone else notice any uneven screen backlighting? I read forums on the v20, and when reading back text on white background - while scrolling down to read more text I notice dark shades on the screen. I downloaded screen test and lo and behold...dark patch on my screen! I then sent it back to LG and assured me that they replaced the screen module and tested it and all 'voltage' was normal - BUT, dark shades were still present albeit in a different spot!
Can someone here please confirm if this is a normal thing for LG screen as I realise it is LCD backlit and not OLED hence a few bleeding / inconsistency of backlight would be present. Even though I have never experienced this on ANY of my HTC's which were all LCD screens.
cheers guys! sorry for the long post!
Yes, i have it too! H910 variant. Two dark/dim spots that run horizontal from edge to edge. Can be more noticeable/annoying in landscape view than portrait actually.
Exchanged one brand new H910 for another. Same problem. Both manufactured 12/16. Havent had this on any other LG Ive owned (RS988 G5, D850 G3, P930 Nitro HD) or Moto for that matter. Pretty bummed to have this in an $830 USD device.
Edit...seems like the issue can be excaberated by different viewing angles. Also, totally anecdotal, but i looked at my display at a stoplight (wearing polarized shades) and i noticed the screen looked unaffected by the shades compared to other LCDs (cars TFT nav screen, an eIPS tablet, etc) that i have in the car. Wonder if what we are seeing is some type of side effect from a polarizing filter, or maybe lack of, used with this display/panel?
Or, maybe these things are edge-lit and LG used an uneven arrangement of emitters. Not really sure.
Good call...I do think it may be the backlight being edge lit! which could only mean (maybe) the backlight has failed at some spots or LG engineers mis-formulated where to put the lighting. it is very sad to hear that this may not be an isolated problem.
I did however sent it back for repair and the technician advice of a NEW LCD module/screen fitted. was sent back to me the same day!! WOW! BUT...same problem but it a different spot.
If this keeps going I may have to consider a new device altogether!
Then im starting to hear crackling on both earpiece and speakers....but thats a different thread!
arrgg...
I began to notice this on my v20 that I bought at the end of December, at first I thought it was just viewing angle or I messed up the screen. However my mom just got a v20 and hers' has the exact same problem in nearly the same spot. I should add that my phone is an LS997 that is completely stock. Also @D0NZ which screen test application did you use to see the problem better?
I used an app called full screen test...its free and simple. I then took a photo of it with my old htc m8 then sent it to lg for review.
The V10s have this as well. Something to do with the backlight and 2nd screen. Kind of got used to it on my V10. Was hoping that would have been addressed with the build of the V20.

But I still have that unwanted effect even if the second screen is off?

I think so. On the V10 it was really noticeable when the main screen went into immersive mode and the 2nd screen went off.

this to me is a deal breaker! I read a lot on my phone, tis why I got a large screen! If this is the 'norm' for a flagship...
I pretty much think its unacceptable. They produce their own screens and cant get a flagship right? hmm...which phone to replace it with now that is available locally (for me that is down under)
So here are some pics I sent LG originally!

Looking at your grey screen, those bands/dim areas are in the exact same locations on my device (and my prior V20)! It must be inherent to this panel. You said the bands/dim locations changed after LG swapped screens/devices for you though?
Either way, it is a bummer. I'm still undecided if I should return mine as well, or just live with it. Almost every recent device has some quirk to live with it seems. I recently traded a Samsung Galaxy S7 that had a beautiful AMOLED display, but the device picked up scratches (on the display *and* body) like I've never seen before. I even took a look over at the dark side (Apple), and they seem to be catching flak for overheating and camera problems in some iPhone 7 devices. Sigh.
I have it on one corner pretty bad, is this because of the IPS screen and how the frame of the phone is pressing on it?

I think its to do with backlight distribution tbh. Ive had a number of HTC's and NONE of them had backlight distribution issues. Im now wondering IF a 3rd party screen module would be better than the original LG produced? OR...if this is an isolated issue only on some devices. My device was manufactured Nov 2016. Maybe a later produced model has better screens? Anyone with a newer produced V20 care to share?
I think its the placement of the 2nd screen backlight. Ill try to find the thread. Someone with a V10 explained it last year.

Here is the post I remember from the V10 forums that seem to make the most sense regarding backlight being uneven.
https://forum.xda-developers.com/showpost.php?p=64236798&postcount=45
Both my replacement V20 and original V20 have uneven screen backlighting (at least the replacement has a better back cover mechanism). There is a dark spot in the middle of the status bar on white (or lighter) screens. What is weirder is that it is the exact same pattern and location as the first one. It is present in both stock and LOS. I suppose I'll just wait around a year and warranty it out then because I just want to start using the phone. I included an image for people that were curious how it looked.
^
I think I can live with that...as in...the dim sections are on the edge of the screen. Mine was in the middle of the screen which i cannot stand!
I have sent the replaced screen NOT to LG but to the place where I bought it.
They said that the repairer that LG told me to send it to was the last on their system as 'reliable'. The store said that they will deal with the repairer and LG. I kind of hope the worst happens and they just offer me a refund or a total replacement - but I doubt that would happen!
UPDATE: so i sent it back to jb hifi, on the report, they can replicate the issue. On the repairers report - they couldnt
SO i get it back with all the 'test' that they have done on it being to manufacturer's specs.
Which i think now...was never good to begin with
Too bad i cant unsee what i can see...sux...I wonder if AMOLEDs have these issues? Anyone care to elaborate?
I have this issue with my LG V20 -- only when viewing photos
I have this issue with my LG V20 -- only when viewing photos - see photos -- screen has two long bright lines.
See attached photos - lines are not on the photos themselves --it is just in the backlighting -- and the lines are not there when viewing websites or if testing the screen with an test app. Please cut ans paste links to see photos - remove blank area after http -- I can't post links till I have 10 posts on this site - if any kind poster could repost so others can see them that would be great!

I have the same issue below secondary screen. Only noticeable on white background. Doesn't ruin reading books, it's there, but minor. I have dual sim variant. I'd be very upset if I paid launching price. All those things you only find out when you get the device.
Being a big LG fan and owning numerous LG phones over the years, I think I join the community when I say the G5 was a flop. I enjoyed the phone over the last year, but it had many quirks that should not exist for a flagship phone. One of those quirks being screen burn in. I feel it started about the 7 month mark and is only getting worse. What worries me is that the new G6, which I very much looked forward to, has the SAME screen!!!! Isn't burn in just going to be an issue on that phone as well or is there more to burn in that maybe I am aware of such as phone temp, heat dissipation and so on?
LCD shouldn't burn in.
Are you sure you don't have a fault with the display on the G5?
I have read about it in multiple forums. Its possible its a fault in the display, but its not just mine.

It`s not burn in, it`s image retention
I have the same issue. Hoping it's not same for the G6.
I was have same problem on g3, g4 and now on g5. I change screen (g5) but same problem
Screen is "same" so i think problem will be on g6
I had a Nexus 5 for 2 years and never had image retention.
I deliberately avoid amoled, so the last half a dozen or more phones I've had are LCD (some of which the display will have been made by LG if not the phone) and never had image retention.
Even my Sony TV has an LG panel.
The last good LG phone was G2, others had burn in issue, I'm pretty sure that G6 will have it.
I know that the technical name isn't burn in but ir looks the same and happens to every LG G3,4,5,V10,20 soon or later.
PS: I was a big LG fan due G2 but got disappointed.
I had "always on" turned on, on my g6
can confirm the clock has burnt in

My LG G6 has a screen burn in that will not go away. Phone is 2 months old. Only noticeable on a light background. It is of the game Pokemon Go the poke ball at bottom of screen is burnt in. Haven't played the game in a week and burn in remains.

same problem.Only grey background and dark backgrıunds i can see noti bar and navbar
Got mine a week ago. It is used phone. I am facing same problem. Is tbere any solution for it? Only visible on grey screen. Navigation bar and Status bar burn in appears only rest of screen is fine.
So far this has been the best mobile device I have ever owned from Palm, to BlackBerry, Motorola, iPhone, Samsung, Nexus, Asus. This has also been the best OS I have used to date. No lag, no battery drain, no boot loop, and I get a removable battery.
Too many features others lack for the same price with less storage for the same money as the V20.
All that being said there is a problem with this phone that also ocurred with my V10. I keep the screen on at maximum brightness all the time since battery is not an issue with this phone (I have many spare batteries). About 7 months into my V10 I started noticing "ghosting" along the left and right edge of the screen. I use white icons which means I always have a dark wall paper. I could notice a very thin whitish smear along the edges. Its not bleed like you sometimes see on the second screen. What I notice goes away when you turn off the screen a while or you switch to a lighter colored background. Then I started noticing that icons for notifications were beginning to burn into the screen when using a dark background... Very odd because this is almost always an issue with OLED screens and not LCD displays like on the LG phones. Then the screen burn in started occurint on the main screen, typically when a bright image is on the screen for a long time and when switching to a screen image with a dark background the borders of the previous image are still visible on the new image. Once the phone is off for while, again, the retention issue goes away but comes back if the same image is on the screen for more more than 30 seconds or so.
Thankfully This does not affect video playback or video streaming. Its only with digital images, logos, or text.
For those not familiar with this problem its called image retention.
I placed a warranty claim on the V10 and a new phone was sent. I traded in the replacement phone immediatley for the V20. And now only 4 months into ownership the exact same problem is occurring... Grrrreat.
When I called LG about the V10 they had no idea what I was talking about. I pointed out that this issue has been discussed in the forums for the last year.
Are you also seeing this issue?

it will go away its not really screen burn in, lcd's have this issue and its common, turn screen off for 24 hours and let the lcd cool off and the ghosting will go away. The LCD's dont have the same screen burn in that the OLED screen would.. but latent images will occur if your keeping it on non stop and high brightness. IPS at its best.
also try and use the screen burn in app and let it spam the screen with the multi colors overnight, this will help cover the burn in like ghost images.
24 hours? Hmm... I will try 8 hours tops because of obligations I need to be available by phone all the time.
I have had IPS displays before that were on all the time and didnt see this issue before...and I run all my devices into the ground.
My Plasma TV has latency issues, my Samsung AMOLED displays have burn in, Samsung LCDs had vertical banding, this LG IPS display has latency...so which displays are immune from premature (in less than one 12 month) issues?

V10 , V20 , G5's displays ( maybe include G6) are quantum dot IPS so they all meet image retention . Other IPS displays never meet this problem
I noticed this issue on my v20. If the phone remains off for a bit the image goes away. It can be annoying but if it doesn't hurt the phone
Sent from my Nexus 9 using Tapatalk
The screen on the V20 isn't a regular IPS, it's a "quantum dot IPS" which may be more prone to some degree of image retention due to their form of illumination (I don't know a lot about it but it's a kind of atomic luminesence) which supposedly increases colour accuracy and range while lowering the power requirement for for the backlight.
It's possible this might be the root cause of the 'ghosting' but I'm mostly guessing.
Ironic though if QD displays are prone to ghosting, and LG knowingly equipped thier phone with an always-on second screen with that tech.
Yes. I'm on my 2nd replacement for the same issue. The phone I'm typing on is now having it. The screens last anywhere from 6 to 8 months before breaking down.
Glad to see that this isn't only happening to me, I find it super annoying, I never had this happen before on other devices, and it's an unacceptable occurrence that of course nothing will be done about it, I for one can't wait to get rid of the V20.
same thing started happening to my v20 recently, around 4-5 month old phone. it's an annoyance that should happen to a flagship phone, but it looks like we're SOL...

Tilted Pixel lines Problem.
I am also facing same problem with my 3 months old LG V20 Phone.
My phone have one more Problem.
I can see pixel lining (in whole screen) even though it is quad hd display. But the problem is that it is not horizontal, It is tilted 10 degree, and there is no vertical lines that I can recognize . And it is annoying to me.
If the screen is equally pixelated then I should have seen both vertical and horizontal lines of pixel equally like you can see in TV LCD Displays.
I encourage anyone whose 12 month warranty is about to expire to file a claim. And not use the phone at maximum brightness unless outdoors. Luckily I had some other issues with the phone like NFC and the speaker being somewhat distorted and the phone was replaced for those issues as well. If you see any deterioration in any other hardware aspect of your V20 you should definitely file a warranty claim.
I plan to keep this warranty replacement for another year as the only phone with the image quality I like is the Sony Experia XZ Premium which doesn't work with Verizon. Believe it or not I compared the V20 to virtually every new OLED flagship anr they all had a dingy yellowy color compared to the V20, including the new iPhone X. The Sony was the only phone that had both the color accuracy like and LCD but the deep color pop of an OLED. Best of both worlds with the only 4K screen and battery life better than my V20

It is my understanding that the V20 will get image retention, but not actually burn-in. Is this true?
Also, I have searched for solutions to the image retention problem. Most solutions advise the use of apps that cycle through colors or simply leaving the device off for awhile. I used a color cycle app, which helped, but the issue returns. And leaving my device off is, simply put, not an option. I did come across a post about replacing the thermal paste. Any truth to this method?
But I'm wondering, if I go through with taking my phone apart to apply paste, wouldn't it be beneficial to also replace the screen as well? Or am I missing some factor I haven't read about yet?

Once image retention sets in it will return once the screen is on for long enough. I ran those screen burn in apps overnight for months. Made no difference at all. The only option is to completely replace the display if you can get it cheap.

No need to do all that, install Night Screen by paper airplane dev team and set the slider at around 80%(make sure you're on the moon icon). Also let the screen cool off before you do this and set it up. You won't really notice the filter much and all the retention problems will be a thing of the pass.
@porscheoscar - No kidding lol Replacement LCD are not cheap. I'm gonna keep an eye on them cause I want to keep my V20 as long as possible. One of the last phones, that I'm aware of, I can carry an extra battery for. I love switching batteries while my friends with their latest, greatest phones watch their battery percentage like a hawk hehe
@salvichulo - Thanks for the tip ^_^ I installed it & am giving it a workout. I try not to be on my phone a lot, but I'm a gamer ;P Once phones became powerful enough to really game on, I killed my Xbox Live account & game exclusively on my phone. When I get the money I'm gonna look into getting an Android Emulator for my laptop.
A bunch of people are on here saying that they notice this ghosting problem after a few months, and that after that their phone's screen deteriorates rapidly. I just got this phone for Christmas, and I love it, but I noticed this annoying ghosting problem immediately. Should I be worried? I'm a little nervous it's getting worse.
why don't you root your phone? By rooting your phone you can change color setting by using custom kernel it help you with this problem .

So.. Just today ive been noticing the remnants of a game or video name being "left" "burnt" (if you will) into the right top to mid side down the ride side of my display.. Any ideas? Has anyone else experianced this? Trying to recreate it but its only doing it very fantly currently.. And barley noticable.. But after i had played my game for a little while earlier i could clearly make out parts of the game remnants on my display..
I get this too but it only shows up on grayish colors and it goes away after about an hour or so. Happens mainly with 2nd screen but it'll do it every now and then on the main one. Brightness seems to affect it's appearance more as well. It shows up more frequently for me when Brightness is @ 90 and up.
same here , i am getting the pixel burn as well. what can i do any suggestion?
I'm getting the same problem, called T-Mobile they're sending me a replacement unit to replace the replacement for the original that was bootlooping.
For all with the problem, I suggest getting LG to repair it since it should be covered under warranty. Also, just thought I'd add that LCD screens don't burn in, like their AMOLED counterparts. I believe you can describe this as ghosting, or just say the pixel is stuck on the same color if a customer service rep asks. I could be wrong, but this is what I've heard for most of my life. Hope that you guys solve your issues and return to a problem free experience!
Guys try a program called Pure Noise 2 and let it work overnight. I never had this issue with my Note 4 but even then I periodically ran the noise program. Let me know if it works!
Residual Image
I have this issue as well. From Google sleuthing I've discovered it is referred to as "Residual Image" and it is not a "burn in". It was said that the lcd tech used by LG has this "characteristic". It does self correct. And, most definitely appears most often with gray backgrounds. After seeing both of my parents s7 Edges AMOLED screen burn in issues, I feel we have the better tech comparatively. yay?

This is pretty much the conclusion I've come to after researching for awhile
Hi, can't remember the last time I needed any help with a phone till now.
I used to love the old Sony Ericsson Walkman phones, then went to Motorola's, and my current phone is a Moto X Play that my contract is almost up on. It's getting old, beat up, and slow.
As I've been looking for a new phone the LG G6 and V30 have really jumped out at me. As I know nothing of the LG brand I've tried to look up as much information as possible about these two models. The same concern has me worried on both models, and that being the screen quality.
On one hand you have the LG G6 which has an LCD screen which appears to still have a lot of image retention issues. So while these may go away I don't think I could live with the issue.
On the other hand, the V30 has an OLED screen which are prone to burn in, degradation over a shorter period of time.
After all my ramblings, my question is this...
How wide spread are the issues with LG LCD screens image retentions, and are the LG P-OLED screens that fragile that I have to be careful not to use it very often?
I've seen both in person, and the demo models both look great. Originally I was going for the V30, but the Pixel 2 issues, and inherent OLED issues got me thinking of the G6 only to find out issues about it as well.
I would need to take out a contact for either phone so I would be committed to a 2 year policy with either one, strangely for the same cost.
Any opinions and help would be greatly appreciated.
LG G6 screen is perfect, I haven't had any problems with image retention in the 8 months I have used this phone. The only bad review of the screen is sometimes the bright is not enough outside when the sun hits the display. But the quality of the colours, resolution, etc its perfect in my opinion.
No issues whatsoever with G6 screen. I am comming from OLED in my last 5 smartphones so I can do an informed comparison. No retention, black level is acceptable (of course not AMOLED level), perfect colors and clarity. Perhaps a bit more brightness could help in a very sunny environment. Cannot comment on V30 though.
For me G6's display is finally something I was looking for for a very, very long time... colors are vivid but not overly, contrast could be better but it's not bad, however as mprovi_15 stated - the display could have better brightness as there were some moments when even 100% in direct sun was not enough.
Also I wish it was a little more battery friendly. It's not bad, I usually get 4,5-5hrs SoT but still OLED screens drain less energy.
No word on V30's display, I've seen it only once in the market on demo unit but it seemed really nice. However there are numerous reports of users having various problems with it, just google "LG V30 display issue".
Thanks for the insight. Good to hear that there are at least a few happy G6 owners. I've seen the screens in person, though I wasn't able to go through and test them in low light, or at low brightness settings, both looked great. Yeah the V30 looked better, but it was an OLED so I did expect.
I've just finished reading a 67 page thread about the V30 issues, but similarly there are also a few about the screen retention on the G6. It would even seem the more I look into it almost every manufacturer seems to have the issue to some extent.
I have an LG G5, which I think has the same display as the G6. I have to admit, I was worried when I first came across the image retention problem! I thought my phone was faulty or something. But you can get used to it. There is also a solution for it. I am rooted and using EX kernel manager, and it has a display control section. I found out if I set red, green and blue from the default 256 value to ~246, it pretty much solves the issue. So if you are planning on rooting your device (which I assume you will, that is probably the reason you are on this website in the first place), then I think image retention is not an issue. By the way, my father has the G6, and have never heard a bad word about it's screen, or image retention at all.
About brightness... Do you really use your phone that much in direct sunlight? You can always cover for the screen, by turning away from the sun, thus casting shadow on it. I think this is a problem that people overdramatize.
I am not a fan of LED displays either, for the same reason as you: burn in. I'm not going to buy any LED displayed phones in the future, that's why I am very happy to hear that LG's new flagship will come with a so called MLCD+ display.
At least to begin with I do like to keep my phones stock. I normally only root or modify them if there is a reason to.
For this very issue I decided to grab my old Galaxy S2 and see what the screen looked like as it's an AMOLED. Back then I was a bit naive about what the screens were. Let me tell you it didn't age well, and the screen looks horrible. Obviously the newer LED screens with better resolution will look a lot better, but if they age similar to my S2, I wouldn't want anything to do with them. Even worse yet if they are poor quality to begin with. I still remember the old CRT burn in and how horrible the screens got on those. It's a definite positive for the G6 as it's still LCD, which in part gives me a bit of a shock that the image retention would even be an issue.
Considering that both the V30 and G6 are the same cost on contract, I may wait to at least see what the G7 has to offer. As the tech seems to get more complex, so do the issues encountered.
I can personally tell you this, I've had both the g6 and the v30 sold the v30. Here's why the v30 is EPIC beautiful phone WAY better bluetooth quality that's for DAMN sure. The speaker quality and mic quality were mich better also. The screen 100% looks worth the $$ for sure. It's faster for sure also. The screen just feels better to touch and to view. I used them both side by side for about 30 days. I kept the g6 cause it feels better in hand. I have "average" sized hands for a 5'8" male so that said the v30 with its slight curve did not feel l "safe" in my hand. I did have them both in the spigen slim armor case. Love that case on all phones. Sadly limted colors but for sure nice case. The v30 is better for netflix or extensive YouTube watching. Of course screen size wins. Let alone the daytime visibility goes to the v30. But I feel that yhe LCD of the g6 is great as well and helps keeps photos, even those taken in HDR more realistic liking the PLED of the v30 seemed to over saturate colors even after adjusting it's color settings. The v30 is the better phone. Period. I however choose to keep the g6 cause I liked the way it felt in hand and truly over all the retail value of a barely used v30 with pre installed class screen protector was well worth selling it. Another thing the v30 is VERY hard to get a nice true glass screen protector for.
AMOLED screens become greenish over time (I had Galaxy S5, S5, S6 and S7, all with amoled) and they all have some type of permanent burn in. That types of displays must degrade over some period of time and you can't avoid that. Here on my G6 no problems with the screen from day one. It is like brand new. No image retention or something similar.
I went back and checked the two units on display and did some brightness and display tests. The LG V30 failed miserably. Extreme burn in even though they had a demo mode constantly cycling images and movies, and when put at 0% the screen was very uneven, and there was enough screen flickering that I could notice it.
The G6 seems dimmer than my Moto X Play, but no screen issues noticed. The screen is roughly the same size as my old phone, though at an 18:9 ratio.
Thanks for the help, now on to find a slim case and screen protector for it.
