[Q] Poor screen uniformity (+yellow tint) - brightness and colour - Feedback Please!

So the Nexus 4’s potentially quality screen has crappy screen issues. There. I said it.
What I mean is that it’s a GREAT screen in some ways (resolution mainly) but it’s let down by what seems to be noticeably poor quality/manufacturing.
Why do I say this? Well, it’s been my experience that the Nexus 4 (in general) has a chronic problem with significantly poor screen uniformity for both colour and brightness. I ordered my first phone on the 13th December 2012 and as soon as it arrived I was pretty excited at finally getting a new phone (upgrading from Galaxy S1 the N4 is a beautiful beast).
When I booted it up and started using it I immediately got a sinking feeling as I realised that the bottom third of the phone had a slight but easily noticeable yellow gradient tint to it along with the left edge and the right edge was grey/dingy about a half a centimetre in. The left side and bottom third were also noticeably brighter than the right side of the phone. I’ve illustrated this in the attached pic. It’s all fairly subtle – but it’s definitely there and is easy to see.
Since I use (like most people I guess) quite a few apps that have white or solid colour backgrounds (gmail, currents, google books, email, messaging, chrome etc) – this lack of uniformity really made things look crappy in a not spectacular but just “sub-par” way unless I was viewing something which was a picture or video or filled the screen where it wasn’t noticeable.
So I called Google Play and told them about the problem and they arranged for a return.
When I got my replacement I booted it up and immediately, even before getting past the X logo animation noticed a big spot of light bleed at the top right. *Very* easy to see and my heart sank.
There on in I opened up the Mail app and closed the keyboard so I got a nice, mainly white screen. Again I noticed the same issue with the yellowing tint to the bottom and left but this time it was *more* noticeable.
To cut this long story short I’ve now sent back 3 devices for this issue, about to send back my 4th and my 5th should arrive tomorrow. I’m not holding out much hope.
I’ve seen this exact same issue on about 4 other Nexus 4’s in shops in the UK (Carphone Warehouse, O2) and while there looked at the HTC One X, iPhone 5 and the new Lumia phones from Nokia running Windows Phone 8. Those phones in particular (with LCD screen tech too) didn’t have these issues *at all* as far as I could tell. In fact the HTC One X screen looked to me to be flawless, as did the Lumia 820 and 920. If I could put the screen from the One X into the N4, I would. Sadly, not gonna happen. Sadly I don’t want the One X but do want an N4. P.S. I know LG manufacture their own displays.
Now I’m NOT claiming to speak for ALL N4’s (why I’ve started this thread) but I do believe that it cannot be a coincidence that ALL the N4’s *except one* showed this issue. I believe that LG simply manufacture the screens in such a way that they invariably have these tinting and brightness uniformity inconsistencies and that because most people don’t care, they don’t care.
********What I’d like is to ask if people with an N4 they’re happy with could do the following and provide the following info:
*Open the Mail app and close the keyboard (press down arrow at bottom). Look at the white of the screen and see if there is any edge or part of the screen that is noticeably *brighter* or *more yellow*. Are there any areas of the screen that are noticeably darker or duller? Do this for different brightnesses (low and fairly high). What do you see? Any yellow tint? Any inconsistency in brightness? All ok? Perfectly even?********
TL;DR: I’ve had 4 Nexus 4’s from Google Play all with the same yellow tint and brightness uniformity issues. Very noticeable. Not acceptable to me for a device that displays a lot of white “pages” and solid colours. Other phones (that I don’t want) do not have this issue (annoying). Please can you give feedback from your phone.
PLEASE NOTE:
Other threads discussing the “yellow tint” issue invariably attract trolls in their varying forms.
DO NOT reply to this thread if you simply want to say any of the following:
1) I don’t see a problem with mine therefore I don’t understand what you’re talking about.
2) I don’t see a problem with mine therefore you’re imagining a problem with yours.
3) I don’t see a problem with mine therefore you’re expecting a “perfect” screen and they don’t exist.
4) There are more important things in life to worry about. (A: I’m not “worried”, screen uniformity is important to me, get over it.)
5) I see a slight yellowing but I don’t care therefore you shouldn’t care. There are more important things in life to worry about.) [see above]
The attached illustration is slightly "exaggerated" to make sure the effect is reproduced for all screens. Not by all that much though.
UPDATE: 31/01/2013: Well I've received *another* N4 replacement today and lo and behold the exact *same issue*. With this one I'm going to wait it out at least a week and see if it improves. I *really* want an N4 as in every other way it's truly a great piece of tech. Pray for me guys!

My screen has no discolorations or brightness unevenness that I can see.

I've had tint issues with all three handsets. First two it didn't disappear after use. This third handset SEEMS to have gotten a little better after a week.
All three had light bleed. First one was least noticeable, last two including the current have two blobs of light bleed in the exact same places along the top of the LCD.
It's almost as if something during manufacturing (screw tightness?) has caused it on both handsets. They are both 212K and revision 11.
It's annoying me and I may do one final RMA once I see what this new wave of devices brings.

mine's fine.

I did what you asked, OP and I'm not seeing and unevenness, yellow tint, or brightness issues (aside from auto-brightness being stupidly low).
The only issue I have with my screen is poor colors. I have a One X and an iPhone 5 that I sometimes compare with my N4's screen and it's shockingly apparent that the N4's screen has colors that just aren't worthy of a top-tier device. The resolution is nice and all, but I like it when the colors are nice and accurate. It's most easy to tell when comparing images of people and looking at their skin. Now I'm no anthropologist, but I have a pretty solid grasp of what skin looks like. The One X is probably the best at representing things the way they look IRL, followed by the iPhone 5. I don't know if it's just my N4 or other people have the same issue. I've tried using apps to adjust the color (FauxClock with Faux's kernel, to be specific), but nothing makes it look quite as nice as my other phones.
I guess you never asked about the second part, but there it is.

I had that issue when I received my device, Used kernel setting to rectify the problem but after 4-5 days of use it gone away. Now device is perfect.
I recommend you to stay with it for 3-4 days before returning it and check.

Thanks for the feedback - very helpful. I got *another* one through today and it seems "better" by a bit than the previous one at least. I think I'll see how it goes. Good to know that it's not only me sho can see the difference.

All the phones I've had have been 301K and they've all had the same issue with yellow tint/backlight inconsistency in a very similar way. I'll have sent back 4 N4's if I decide to keep the current one! I think you're probably right about the screw tightness or some such other minor thing during manufacturing. It's not like a viewing angle problem. It does look like something to do with assembly in particular. Please do let me/us know how you get on and how things work out.

I used FauxClock on my previous device (sat here waiting to go back) and it did seem to improve the situation slightly - but then since the screen isn't uniform, it reduced the yellow where it was yellow but then made it too "blue" on the rest of the screen. I really hope that this yellow tint is a "glue" issue or something that will even out through repeated use due to heating/cooling - i.e. expanding and contracting which somehow settles things down. I'll keep this one about a week and see what happens. Fingers crossed!
Thanks for your feedback guys!

^ this is pretty much all I can say.
Every nexus 4 phone I handled had a slightly yellower screen at the bottom. For me its barely noticeable, not as yellow as it is in your illustration.
They all seem to have that same issue, along with light bleeding across the top edge.
You can keep RMAing if you're not tired of that .. But you will not receive a fully uniform no matter what.
If screen uniformity is important for you get one of the above phones you mentioned.

Thanks for the info, that's interesting to know. Out of interest, how many have you handled? Going by some comments on XDA and around the web regarding this issue, you'd think that the yellow tint was only on a handful of handsets and an isolated quirk, not as I suspect and you seem to suggest, a common trait of the N4.

Well,
I ordered three of them, all screens looked identical with the exact same issues: some yellowing at the bottom with a light bleed over the top edge (especially top right corner). I had to RMA 2 out of the 3 due to severe screen issues (screen flickering and dead pixels). Received 2 new units, screens have the exact same issue. I have 2 friends with N4s and their screens are like that too. It's almost not noticeable.

Does the light bleed appear like small blobs from the top edge?
My worst is the top left, about an inch in. Then there's another smaller blob nearer the right hand side. Little bit leakage top right and top left, but its worst along the actual taskbar.
I will take a picture tomorrow.

My first nexus 4 (rev 10) has perfect whites except the bottom of the screen would turn yellow after warming. All of the 4 RMA devices I've recieved (rev 11) don't have this issue EXCEPT all the rev 11s are calibrated horribly leading to the entire screen being yellower than my rev 10 unit. The screens are uniform, however, I just wish they calibrated the phones like they did with the rev 10.
The new rev 11s have a calibration problem while my rev 10 has a glue problem.
The new rev 11s also have a dimmer screen than my rev 10. I kinda just want them to send a perfect rev 10 to me.

Interesting because calibration issues affect the whole screen. If any part of the screen isn't the same "tint" as another part and its noticeable then this isn't something that can be fixed with calibration. Calibration can only save a uniformly "yellow" or "blue" tinted screen. To that end I wish mine was uniformly yellow. Mine is a rev 11 and I'm on my second day with it and hoping the bottom and left yellow tint fades soon and that it's just glue. I've tried Fauxclock and applying various screen tweaks with a previous similar phone and it helped somewhat but there's nothing can be done about unevenness in the tint really unless its glue and it dries.

G3 visible screen texture (LCD issue)?

I'm contemplating returning the G3 but need to ask everyone who owns the model if your units suffer the same issue or if this is just an LCD issue in general. I'm comparing on white backgrounds this noise/textured pattern reminiscent to a digitizer somewhat that literally for me defeats the purpose of having a QHD screen since it's the only thing I notice. When looking at my S4 AMOLED there is no such issue, and I just checked out the HTC One M8 with its Super LCD 3 in store and it doesn't seem to have the issue. The Xperia Z2 does also have this effect as well. Can anyone comment on this, and tell me how does it not distract you if it is there since for me it is a deal breaker!

I see it too- I just assumed it was my screen protector though...
K

I just realized this. I don't think a replacement will help. Seems like a panel problem. Until LG acknowledges this and ships out a fresh batch, I think I'll hold off on a replacement.
Sent from my VS985 4G using Tapatalk

I've seen this on every G3 so far that I've looked at. It's not the digitizer because you'd see that when the screen was off.

My AT&T variant doesn't have any visible digitizer pattern

i dont see it on mine either

Its very hard to see. It can be seen on a white or light grey background. It almost looks like pixelation. Hard to explain.

It's not a digitizer pattern, definitely has to do with the lcd. Just reminded me of a weak digitizer annoyance. You have to look for it though but once you notice it you'll never unsee it

Seems like a vague statement. With the incredibly powerful cameras and even microscopes that can be done to really see these screens in detail, where is a picture of this 'visible screen texture'?
I can put the display all the way up against my face and can not see any texture you speak of. Please help to explain or at least show what you're talking about

OK do you have your G3 rooted? Probably you've got G3 with JDI panel, why don't you try to find it out and vote in that thread http://forum.xda-developers.com/lg-g3/general/g3-display-manufacturer-t2824310 ? Sony has also such patterns because they also use their own JDI panels.

I think that someone here is "looking for hair in the egg"!

I have this problem as well. I actually thought it was a real problem and went to get a replacement about 4 times. After the fourth one, I gave up after noticing that a lot of the G3s have it. I looked at a lot of display models (best buy and att stores) and looked at a lot of G2s as well. At first I was really annoyed by it, but now I've gotten used to it

I can see it on mine in certain conditions, but most of the time it's not visible. Same with any other device I've had, really.

I think I see what you're talking about, I just don't know how to explain it. I can only see it on a bright white area, and I'm guessing it's a result with the panel and how high the resolution is. I don't mind seeing it though... I don't see it as a defect since others are reporting it. MUCH less of an issue (if one at all) compared to a yellow screen area or something. Comparing this display to 1080s which never did this isn't fair. The technology is too new and doesn't have anything to compare to.
Not everyone can be expected to see it or notice it, especially since near sightedness is going to vary amongst people. Uncorrected, I can see extreme detail on objects within a 1-2 feet, but I can't see any details past 20 (signs are unreadable, etc). When I am using corrected vision though, my near vision gets slightly worse and the effect is less pronounced.

Yep, I noticed this as well. However, it is mostly only visible when the screens shows only a single color. E.g., it's really visible if you use an app like Dead Pixel Test. Under normal conditions, I've only seen it a few times, which is fine with me. The real problem still is the oversharpening.

I have seen maybe about 30 different G3s now, all of them have it but with varying levels of visibility.

It's one of those issuses there is probobly no point worrying about. All G3's probobly have it, nothing we can do about it (at the minute). If it bothers certain people that much, get a different phone

Done and done! Switched to the M8 and the super LCD screen is fantastic, Crystal clear. Love the G3 and I'll miss it but once I noticed that issue it was basically game over for me.
Sent from my HTC One_M8 using XDA Premium 4 mobile app

I agree with others that it's only apparent in unique moments, typically where black text is on a light background. After a bit of thought, I've decided that certain apps are not able to display the high resolution that the G3 can produce...so dithering artifacting occurs.

Its not an issue. I have seen it on every single lg g3 and its only visible on high brightness with a white background. And it seems like some models show it more than others, but most are acceptable.

Users with defective screens (pink/uneven color temps), what model do you have?

I'm on my 4th phone, and this one is by far the worst. I busted out my Galaxy S4 to compare, and it's night and day difference. The S4 (also super amoled) is completely uniform color temp, and has almost zero color shift when you tilt the phone. Every 6P I've had has some type of pink to blue color gradient, and shifts to blue when I tilt it just a tiny bit forward (like everytime I'm reaching for the notification tray). I'm starting to think people with "zero issues" are either smoking the hype pipe, or having a completely different experience. All 4 of my phones are 64GB Graphite, with build dates of 10/25 or 10/27. It seemed there were a disproportionate number of 64GB Graphites reporting these issues. I'm thinking I keep getting phones from the same crappy batch(es). I'm wondering if there is any correlation between the color/size variants and these defects.
I'm considering returning the phone for good and either reordering in a month or two, or getting a 5x to hold me over until next years Nexus. I got Nexus Protect and the whole shebang with the 6P because I was planning on keeping it 2+ years.

2x bad 64gb graphites for me. 3rd one seems to be better, but not perfect. I'm not sure if I'll RMA it or not. Like you said it seems like every screen has issues and it's just a matter of how bad it is. The 3rd one isn't too bad at least.

Frost 128gb, no problem at all except for the random reboot.

Frost 64GB and same as you, no defects but I need to check if I got a random reboot while asleep as it asked me for the secure boot password when I unlocked it this morning. Strangely, once I did this, the phone appeared to have been exactly where I'd left it, instead of going through the usual boot up process of loading home screens, widgets etc.
I do wish to clarify that I do find this device to shift colors ever so slightly when not looking straight on. It is nothing major and I put it down to Google/Huawei not sourcing a good panel. It is the obvious shift expected from lower end panels due to changes in viewing angles. I do not classify that as a defect. I will post pictures of this in another thread in General.
At the most extreme near 180 angle, I can see some green rainbow effect. I don't know if this is due to my cheap screen protector or it has something to do with the Gorilla Glass treatment on the panel. It really is a non issue for me. I NEVER noticed ANY of this until I came along the forums and read people complaining about defects, making me go LOOK for them on mine. This doesn't mean others aren't suffering from defects.

Mine had the freeze and reboot issues. Did it 7 times in the span of 5 days. Put it on safe mode and still rebooted. Factory reset the device and clean install of apps and rebooted once. After that one random freeze, the device hasn't had one in 48 hrs and counting but still rma'd for a new device to make myself feel more at ease knowing that there is no internal hardware issues.

Not had any reboots at all but my 3 phones had increasingly worse displays. Alu 64gb, manufacturrd 18/10, 28/10,28/10. The original 18/10 was the best of them all but still not good with pink hue on the left side of the screen.

I also have the color shifting, but this is probably caused by the tempered glass screen protector. anyway, I always look a the device with an angle of 90 degree.

Thanks mods for cleaning up the hate speech. It amazes me people think we should be grateful and accept any crap Google ships. The way QA works, it's not an issue unless the customers make it an issue. If Google can save money and use grade B panels, and their customers don't seem to mind, then next year they might use grade C panels.
This is what my 6P looks like on the google homepage at normal brightness levels: https://goo.gl/photos/z77YPDta247Jh3Zt5
Last I checked, there is no gradient on the google homepage that goes from pink to green. And if you're curious, here is what that looks like next to a Nexus 5X: https://goo.gl/photos/3huN7dPbeBKqrodf7
Every one of my 6Ps has a color gradient when looking directly at the screen. That's not taking into account the crazy rainbow effect when you tilt the display just a few degrees any direction. I had multiple Galaxy S4s, which also have a samsung amoled screen, and they are all completely uniform and have close to zero color shift at normal viewing angles.
So to everyone that thinks we are just picky @#[email protected], in all my years and hundreds of consumer electronic devices I've owned, I've only ever RMAed two other devices: a plasma TV that buzzed like a bumblebee, and an og PSP that had dead pixels and completely outrageous back light bleed.

Fix uneven/yellow screen with intentional burn-in

So I was on my 2nd Nexus 6P and like the first it had an uneven screen. Normal/slightly pink at the top and at the bottom it's more yellow. Instead of returning it I've decided to try and fix the yellow tint by intentionally causing a burn-in on the over-enthusiastic green pixels in the bottom half of my screen.
To do this I flashed a kernel which unlocks the high-brightness mode of the display, the awesome EX kernel, set my screen timeout to 15 minutes and left the display turned on for 3x15 minutes in high brightness mode with a black-to-green gradient open full screen in the Photos app (absolutely nothing else on screen). After each of the 15 minutes I checked the progress, after the 3rd time I considered it done. I'm happy to report that this has nearly eliminated my uneven screen problem.
So far I've seen no ill effects, just a nice even screen.
I used this black-to-green gradient that was a close match to where my screen was yellow. My first 6P had a different pattern of yellowness, so that would have required a different gradient, more like black-green-black.

Interesting, the normal slightly pink at the top transitioning to yellow at the bottom describes the screen on my original nexus 6P and it's replacement.
I'll look into giving this a try as well.

I´m not sure if something like this could be considered as a defect. If you look at a very high angle, you might see some sort of "rainbow effect" on the screen. You should be careful about "burning in" Pixels in a Amoled screen. High brightness will wear out the LEDs faster than you think. At least this is how I remember my old Samsung Galaxy S3 but maybe Amoled technology has improved a lot.

I can't really comment on if the OP's method is safe or not, but it is worth noting that the gradient/tint change is noticeable even when viewed straight on under normal use, such as browsing etc.
It could sort of be likened to the old TN based flat screens from a number of years ago where the top and bottom looked slightly different colours, however a lot of this was down to narrow viewing angles. I'm wondering if the same applies to the specific AMOLED display used by the 6P as well.
The AMOLED screens on my Moto X 2nd Gen and Moto X Force don't have the same problem.

I have a slight purple tint too on the screen but it is only visible on a white background. It does not bother me, if you set a higher brightness it is barely visible. Maybe all Nexus 6P have this sort of display and you simply have to live with it.

Would you happen to have a before image for your screen? I would like to try this on my phone but can't say for sure what exact color the uneven section is. Most of the screen seems to have a pink tint that fades into a green/yellow tint in the bottom left corner. I don't want to stress the wrong color accidentally.

Can you post before and after pics of your screen please?

Its a well known characteristic of samsung AMOLED screens. Samsung users have been complaining about this for some time. Its actually worse on the sgs6. But more brightness will make it less noticeable. Honestly, if you forget about it and stop focusing on it, you will stop noticing it.

Yeah I understand some are really bad you should send it back.but if its slight. There's no.point obsessing about it. It takes the joy away from using the phone

It's impossible not obsessing about it since the display is very thing you look at when using a phone, people wouldnt tolerate if it was an LCD, dead pixels or any other defect at the advertised price, but since it's amoled we should be expected that these errors occur.
The issue on slight displays is that the screen is uneven on white, so its impossible to ignore on web browsing and how dark ui and gapps is not provided by Google, I would prefer it to be slightly pink/blue all over not half so you won't notice it.
Not meaning to rant and whine but consumers shouldn't have to accept this or fix the issue themselves, when I show the phone of friends, they notice the inconsistent white background and are shocked when I say its something you have to live with, the features are not going to outweigh the display issue
The joy of the phone is still there, just wish they implement quality control.

I complained about this on my Nexus 6. Ended up buying and returning a total of about 8 phones from various stores until i found the "perfect" one. Its incredibly irritating when you can notice it and its the first thing you see when the pixels light up. Some people may care more than others but im not willing to compromise anymore. AMOLED displays look great, but LCDs seem to have a better yield or QA. I was of course down voted and flamed about this. Good to see people starting to take action against garbage quality AMOLEDs.

So I was on my 2nd Nexus 6P and like the first it had an uneven screen. Normal/slightly pink at the top and at the bottom it's more yellow. Instead of returning it I've decided to try and fix the yellow tint by intentionally causing a burn-in on the over-enthusiastic green pixels in the bottom half of my screen.
To do this I flashed a kernel which unlocks the high-brightness mode of the display, the awesome EX kernel, set my screen timeout to 15 minutes and left the display turned on for 3x15 minutes in high brightness mode with a black-to-green gradient open full screen in the Photos app (absolutely nothing else on screen). After each of the 15 minutes I checked the progress, after the 3rd time I considered it done. I'm happy to report that this has nearly eliminated my uneven screen problem.
So far I've seen no ill effects, just a nice even screen.
I used this black-to-green gradient that was a close match to where my screen was yellow. My first 6P had a different pattern of yellowness, so that would have required a different gradient, more like black-green-black.

This post is old but I wanted to try this nonetheless. You can't just burn in or wear out the pixels in such sort of time no matter what. 45 mis is not enough to cause such an effect. I tried it as I have a screen with the same exactly issue but there is no change. And I did it for far more than you. I let it all the night long for 3 days. There was no change. I don't think you can fix this issue this way (or any other way)

You guys keep saying "AMOLED issue". I bought 6p after having OnePlus X - it has AMOLED without any issue, it was perfect screen! Nexus 6p is great phone, but screen really bothers me... I hate, but I need to replace the phone. And I am not sure whether I will get a good phone or not. Support told me that if I would ask for replacement - they could send me a refurbished phone. Only buying new will give a new phone. I can still return it as I have it for few days...

Hey,
Seriously, a refurbished device just after a few days? Like you had it for 10 months, lol? Is it Huawei?
Escalate the case to a supervisor and don't give up until you get a "proper" new phone!
Good luck...

image retention?

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

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 .

I don't really know how to root my phone, it seems complicated, and wouldn't it void the warranty?

You can use app Nightly from Play Store, set to 75% and ghosting effect disappear
