Green tint to screen? - Moto Z Questions & Answers

Green tint to screen? - Moto Z Questions & Answers

Not sure where to ask this, so here goes. Picked up a Z Play for my wife and it's great. Then picked up a Z for myself and while it looks and runs great, there seems to be a definite green tint to the screen when viewed off-center. And I don't mean 30-40 degrees off, but as slight as 5-10 degree off center, in any direction and it has a definite green tint, regardless of brightness setting. Previous AMOLED phones for either of us never had issues until extreme angles, and her Z Play is far better, not turning green til about 40-50 degrees, which is what I would expect.
Is this common or an issue? It's only been a few days, so I can go change it if it's a known issue of any kind. I guess I can also go compare it to display phones.

Mine doesn't appear to have this issue, perhaps a slightly noticeable change when 40° off but not at 5/10.

Me neither, nothing remarkable happening when tilting it in either direction.
When the Moto Razr XT910 was new, there were many reports of varying panel quality problems, such as strong green or yellow tints
They did get new phones when they returned them, as it was a quality issue, could be the same thing now.
If I'm not mistaken, those with lots of green had field/cloud faults when viewing a black image in a dark room at full backlight, as they failed to reach zero brightness.
It was described as the pixels leaking electrons to surrounding pixels.
Viewing angles on the Z is worse than my old Moto X 2014 for sure, but it's probably due to the smaller pixels.
Nothing beats the old HTC One M7 though, that thing never faded, but it had an IPS screen.
However, in standard colour mode, it's heavily yellowish to reddish (some would call it warm colour temp)
In dynamic it's closer to white, but with a strong nudge to the blue spectrum.
Can't wait to get the custom colour temperature setting with Android 7.0!

[Q] SGS 2 - low light reveals screen defect?

There are a few threads out there that have touched on this issue but none as far as I can see that deal with it directly.
The problem comes when you display a pure black screen in low light conditions. It shows that the AMOLED screen is actually grey / blotchy / cloudy instead of being pure black. Initially I thought mine had fingerprints or smudge marks on it, until I realised they were behind the screen. I guess I might have got a phone with a screen that was replaced, but the amount of people who have also reported a similar issue leads me to believe that it might be a manufacturing default? The blotches / clouds on the screen dont change, but exhibit a random formation as one would expect from a defect. It is also possible to see a very faint outline of light running along 3 edges of the screen.
Naturally this is a situation that doesnt reveal itself very often. But I as I use my phone a lot at night, especially reading ebooks or watching films, you start to notice it more and more where you have large expanses of empty black screen.
What I would like to know is how many people have got screens that exhibit this behaviour and how many of you have sent them in for service or had them replaced?
Is it a common issue and something that is to be expected from this type of screen?
You can test if yours has this problem using 'Screen Test' (its free) from the market place. It cycles through solid colours and patterns every time you touch the screen.
Just do it in bed with all the lights out P), give your eyes a few seconds to adjust and see what your screen looks like displaying pure black.
I'm very interested in everyone's experiences and any input or information you have.
Thanks everyone in advance!
ps: I came from a ZTE blade (OLED) which has a uniformly dark grey background when displaying pure black. I kinda expect this as it is a budget phone (albeit with a better than budget screen), but I didnt expect the SGS2 to be quite as bad.

Use "screen adjuster" from the market and set contrast to -60

i have never seen this black low light screen defect. but i am asking you people if any of you have noticed that ugly blurry shadows which are perfectly visible with low light, on white backgrounds especially. they look like marks above the actual display and make high quality images look like low resolution.. it is annoying as hell..

I have this. Noticed it one night when my phone was switched off and charging.

I also have this, noticed the first evening i used the phone...you can notice this during the screen wake delay, or when in a call if you cover then uncover the proximity sensor...don't know if it's a defect but sure it bugs me, i know many won't notice it and will say they don't have this...i will add that if u look carefully to the screen dimmed at lowest brightness in a low light (buy not dark) environment, like early morning, you'll see some "interferences" behind the image, also the darker/yellower left half screen is still visible in these conditions
These things shouldn't be there in a 500€ phone

Thanks for the feedback already.
@elmerendeiro: I have also noticed some 'interference' lines on my phone from time to time. I did a bit of research and it seems when your phone's brightness is set around 25 - 30% it picks up interference from either the wifi or 3g radio. Notch the brightness either above or below this level and you wont see it anymore.
I agree with you when you say we shouldn't be having these problems on such an expensive phone.
It bugs me too - if it wasnt for this i'd have to say it would be an amazing phone
Might give the Samsung service center a call and see if its something they're aware of and if they are replacing screens with this problem?

Display not TRUE BLACK ?

Hello,
Im Using Amoled Smartphones since the Galaxy (i7500). They all were always showing at 100% Brightness for Black parts of a picture a true Black like the Display is OFF.
If you put the Brightness to 100% and go to an complete Dark Room and open an Black Picture you see some Gray/Yellow Tint on the Screen. You can compare this good by locking the phone to see the Screen OFF and than unlock it to view the Black Picture again. You should see a huge difference. Hope to hear from your experiences.

I've seen that already on the S1 when abusing it a a nightstand clock.
Best guess I've heard is that the (AMO)LED screen leaks some luminosity to other pixels in the background which is then visible as a very faint glow.
However I rather believe that the AMOLED are not truely off but rather get some leak voltage and thus have a very-very-very faint glow (like one photon per second xD )
That would explain the black spots most people seem to mind on AMOLED when on minimum brightness with a black screen; they are truely off or without insufficient leak voltagage (LED's requie a minimum voltage to work).
AMOLED production is somewhat complicated (very thin layer of silver as a power source and a control-layer) so I wouldn't be surprised if the above is true.
Nothing is perfect, especially not a rather new technology.

It's not backlit is the point.

Correct me if im wrong here but amoled is, by design, not backlit.

Yeah so I was wondering why it does this little/ hard noticeable yellow/gray tint on a dark room...
There is no Backlight... Unfortunely i Sold my Galaxy S2 so I cant compare it.. But im Sure it wasnt like this

I have this on my gsiii and also on the Gnote... I think is due to the pentile screen

I had this on my Fascinate but realized it wasn't a big issue. Definitely more noticeable on my Gnex but it also has more pixels so that could be why you see more light. I wouldn't call it a problem because the majority of the time it's absolutely unnoticeable. Each pixel has so have some sort of voltage to be ready to react to changes. Turning off/on completely each time light is needed might waste battery.
P.S. I'm noob at displays but that's my theory.

I was curious about this issue as well. It's my understanding that OLEDs do not produce any light in their inactive state.
Regarding your theory, I wonder if it's similar to plasma displays. Even though plasmas are capable of true black (they do not use a backlight) The individual plasma cells have better response times if they aren't fully discharged on blacks. So they have a faint glow that comes from the low power they are using to keep the pixel charged up and ready to go when a color change is needed.
This actually costs a little power though, rather than saving it. So if thats what they are doing, it is for screen quality reasons so that movies and other things look better.
Did some Googling and I couldn't find much information, but there is talk of delivering pre-charge voltage to the OLED pixels to improve response times. So it could be that they are indeed similar to plasma displays in that respect: Capable of true black, but the benefits of not using true black are too good to pass up.

Are you SURE the picture is actually true black? By that i mean pure 100% black in an uncompressed image? If not then you cant expect the phone to display true black. A JPEG of black may not be enough.
My screen it totally off when displaying true black.

I can confirm the screen showing a faint glow on S3 with a true black screen.
Use Firefox with Fullscreen extension (Chrome and the default browser don't seem to have fullscreen mode yet) and go to http://d4f.pf-control.de/black.html
That's rendered on the phone so we can expect it to be the blackest black an app can produce, however in a (very) dark room you'll see a very faint glow coming from the screen and you'll be able to see the black spots (truely black) that people keep complaining about.
The theory about it being a precharge voltage does indeed sound plausible since LED's have a certain reaction time which unfortunately cannot be compensated by e.g. Overdrive as is used in LCD screens.
Note that the S3's "black" is still far better than any LCD.

No mine is still jet black, no light at all.

Go to a COMPLETELY dark room and make sure the screen is actually turned on when on the website (not timed out).
Then take a long-exposure photograph of your phone (still make sure the screen is turned ON!).

I don't have a long exposure camera, but the room is completely dark and my eyes have adjusted, there is no light.

All sgs3 ( as sgs2) screens emit a very week glow on a black pictures ( with the screen on )
Sent from my GT-I9300 using xda premium

It would seem to me that the 'ink spots' many have are not overly dark spots at all, they are what the screen should be. My screen emits no visible light when displaying a true black image, at least nothing my eyes can see, even at the edge of my vision field where light cell are most sensitive. My screen is on maximum brightness.
My screen has no patches, no streaks, no spots, no pink or excessively blue tint. I guess i have a screen thats as near to perfect as they get.

yes there is very faint glow indeed making the screen a bit greyish instead of pitch black

I don't think anyone is trying to paint it as an issue that needs to be resolved. It's more of an odd technical mystery rather than a real problem. The blacks are still extremely deep on an AMOLED, just like with Plasma it puts LCD to shame in that department.

How is the screen uniformity so far?

How is the screen uniformity on your Note 8 (outside of Adaptive display) I avoided the S8/S8Plus due to the red tints that affected portions of the screen, Ive seen a total of 20 display units for the Note 8 and only 7 had good screens the rest had 'dirty' screens when the display mode was changed to Basic/Amoled Photo, its a combination if either partial red tints or yellowish tints on sections of the screens and the demo units were just installed.
I check the screen with Basic mode, brightness under 50%, fire up chrome and check in landscape, also i use the stock sms app in landscape and i check if its grey background is 100% even from left to right.
I am just curious if Samsung has upped the quality control or its still all about panel lottery ?
EDIT:
Im more interested on feedback that is using Amoled Photo or Basic, as Adaptive mode drowns the screen with a more blue.

My eyes are very sensitive to the red or yellow tints. In Samsung's case red.
My wife's and I note 8 doesn't seem too bad, some red tints around edges depending on veiwing angle but very acceptable.
Mines running basic model also

Adaptive mode here. Absolutely flawless, thankfully. My S8+ had tinted edges but that was fixed by the update they pushed out after adjusting the edges color. My Note8 is hands down the best screen I've ever seen.

When say edges is it on the curved edge or even on the flat part at the top ? as I've noticed most of the red tint is from the top part.
Im also very sensitive to this, other things I have accepted like the grey full screen uniformity on AMOLED is just terrible compared to LCD.

I was hoping that this issue would be fixed. I had an S3 with bad color uniformity issues. My Note 4 is darker along the left edge.
Can't stand the tinting issues that these seem to have. Also dislike brightness uniformity. A lot. I understand that each panel is different from the next, but what is it that causes these issues?

this is why

It's better than my previous note, which was a 4 but still the white isn't as white as some lcd panels out there. I didn't notice any uneven red tint on the N8 either for mine or the wife's. Tilting and viewing and looking out for it I see it a little around the curves of the screen, nothing that concerns me. But there is some red tint in there but not as bad as some note 4 or 3.
Good thing is , there is an adjustment that can be made in the display setting to reduce the red hue should you feel the need. I'm liking it as it is in Reading mode.
My ZTE Zmax whites look better.
Sent from my SM-N950U using Tapatalk

So to summarize, it's relatively uniform but I can still see a pink red crush/hue is present when white is being displayed. Using AMOLED adaptive reduces the red pink hue but looks like trash elsewhere.
So,yes it's still pink. Not much has changed since my Note 3 or 4 days. Then again those were pink or red in parts of the screen. Least the N8 is uniform pink.

I would also like to know the technical reason on whats causing it other than "manufacturing variance" and up until now samsung has not addressed such issues and some customers even struggle to have the devices exchanged.

No, I dont have the resolve to go through that exchanging bull**** anymore, too old for that. Ill either live with it, or send it back .
Last iphone I had owned was the the 3gs and 4s, yellow tint bull**** on those also.

I've had so many iDevices and Macs and never have I seen a screen that I'd even consider good, especially in the area of uniformity. Always darker on one side or the other. Always a bit more yellow here, than there. I've exchanged so many iDevices over the years because of screen issues. Every iPhone release is loaded with crap screens. At least according to all of the threads on various internet forums and groups. That is one of the reasons why I've never tried an iPhone.
FedEx lost my Note 8 and I might just say screw it and stick with the Note 4. My wife's Note 8 has the best screen that I've ever seen on any device with a screen. The brightness is completely uniform. I'd say that it does favor red a bit, but I'd hardly call it pink. Very nice screen.

Indeed, mines not pink like some of the S8 images posted. but there is some hue all over it especially as I normally run "basic" screen mode. Turned the red bar down a little and or use adaptive and makes it ice blue, I can live with it.
Another observation I noticed, if the screen is in Basic mode and I turn on Blue light filter setting, but turn down the bar for the filter to min, the slight pink hue on Basic mode goes away.

Can you adjust the colors independently in all modes or just adaptive display?

Just curious, isn't "warm" supposed be somewhat yellow color in tone ? It seems like when you make the screen warmer it goes pinker.

I have a professionally calibrated workstation display at my office. Whites look like paper and I adjust everything to mimic it.
I was able to get really close by adjusting in adaptive mode.
Problem is with our devices we take them everywhere and the environment changes dramatically, bright, dark, pitch dark, etc.
This plays tricks on our eyes big time! So what may look perfectly fine in one scenario may take on a very blue or very reddish hue in another.
You will drive yourself absolutely crazy trying to adjust all the time!
Like an EQ on a stereo, you adjust contour for flat response and leave it alone! (but most people constantly tweak it!)
Find a reference point and you will be good.
My panel is very consistent.
You want to see a bad display look at the Surface Pro! They may have decent color when calibrated but when the lights go out HOLY BACKLIGHT BLEED!
I am so done with LCD and just want AMOLED on everything NOW!

While what you're saying is generally accurate, that's not what people who have the red tint or purple tint are complaining about. I've seen many amoled screens from Samsung flagships that I consider defective due to extreme hues that can't be "adjusted" to normal. In addition, only adaptive mode can be adjusted, so when the screen is bad, you cannot use any other screen mode without the tint ruining the quality of the display.

BOE screen issues

I sent back an Mate 20 Pro because (with LG screen) I had intermittent data disconnection issues. I had no gluegate screen issues, the screen was fine. The replacement device has a BOE screen. In comparison to the LG screen, after a few days here are my observations:
- The screen has a greenish tint (not gluegate) when viewed from the side. View the screen at about 45 degree angle (left, right, top, bottom etc.) and the color changes.
- Brightness: the BOE screen I have seems less bright than the LG one.
- The screen also seems less sharp than the previous LG, I would describe it as a bit "grainy" or "noisy", not the pin sharp display you would expect at this resolution
- Low brightness: when the brightness slider is low (10% brightness or less), the grey text breaks up on a black background when scrolling. Here is how to reproduce the issue.
1. Go to Settings and select the BLACK background mode. All text is white or grey and the background is black.
2. Set the brightness slider to minimum
3. Select a submenu in settings (e.g. Battery) then go to a dark room (with brightness at minimum)
4. Scroll slowly up and down the screen in the Battery (or some other) settings menu
5. On my screen the light (white and grey) text breaks up into green/magenta components. When the scrolling stops the text is white again. It's like the screen can not keep up with the scrolling, can not refresh the pixels fast enough so the white text breaks up into various colours.
Anyone has experienced this issue on either an LG or BOE screen? Any feedback is welcome.
I am not pixel peeking. I noticed this behaviour while adjusting some of my settings on the new phone. I did not see this at the LG screen. Because my old phone has been taken back by the courier I can't do any parallel comparisons.
This screen is a BOE screen, serial number 18B08. on the latest 122 software version. Based on my subjective observation the LG screen was brighter and did not notice these low light issues (however I was not looking for it in all fairness). Update: now on 146 software update.
Any feedback is appreciated.
===============================
Update (9 Dec 2018)
I went to a local store and took some comparison pictures / videos between store units and my BOE screen Mate 20 Pro. See them below. All videos taken at MAXIMUM screen brightness on white background to compare the quality (max brightness and colour shift) of both screens.
Here are links to 2 Youtube sample videos:
https://youtu.be/t_BSsJi0f1o - My unit vs a O2 store demo unit
https://www.youtube.com/watch?v=AUPe-z5ArfI - My unit vs a Three store demo unit (verified with LG screen)
Some images also attached.

The green 99% of people report on LG displays is in completely unnatural conditions that would never occur in real life use. They use a grey background, turn the brightness down to 1 and see a tinted glow coming out of the curved part of the OLED display that isn't even part of the actual display area.
The fact that the BOE display is not as bright and smooth as the LG display has been reported by many owners and is also likely the reason there is less light bleed coming out of the curved edges when people use the same unnatural conditions--the BOE screen is natively less bright and powerful at every light level including 1. If you research exactly how AMOLED displays generate color you will understand what I am referring to.
Even though the LG display actually seems to be far superior to the BOE display in normal everyday use with better colors, contrast and pixel response Huawei will probably be using the inferior BOE displays going forward because of the hysteria of some users that believed the LG display was defective.
As far as I know the curved OLED display was used on the iPhone X but not on any Android phone before the Mate 20 Pro so doing the same unnatural display test with the curved Amoled on the Mate 20 Pro and the non-curved Amoled of any other Android phone is obviously not going to yield the same results. The light bleed only manifests where the curve in the Amoled is.
Huawei said this was normal but some people loudly insisted that it wasn't so now going forward everybody is going to get the markedly inferior BOE display.
AMOLED displays do degrade over time so it would be interesting to compare how the LG and BOE displays each hold up but since people are only interested in the newest phones that comparison probably won't happen.

Wow dude, you don't know what you are talking about...
The green is totally defective and can be seen in many normal conditions!
The fact that it's emphasized by grey screen doesn't mean it cannot be seen.
I now have a BOE screen and cannot be happier, colors look excellent compared with my Galaxy S9+
LG green screen was crap. And I'm not biased towards LG, I have a very nice OLED 4K tv at home.

I found myself on Spotify with a really distracting green uneven smear all over my screen.... That wasn't a unnatural situation.

biggest pile of rubbish ive ever read in the nicest way possible. to dismiss other peoples experiences just because you havent seen it is rubbish. my friend used my phone in the car at night ( i was using it for sat nav, is that normal enough?) they went on the spotify app to change the song then asked me why is the bottom half of my screen green. if thats not an unusual use case then no one can use their phones at night?

I am not pixel peeking. I noticed this behaviour while adjusting some of my settings on the new phone. I did not see this at the LG screen. Because my old phone has been taken back by the courier I can't do any parallel comparisons.
This screen is a BOE screen, serial number 18B08. on the latest 122 software version. Based on my subjective observation the LG screen was brighter and did not notice these low light issues (however I was not looking for it in all fairness).
Any feedback is appreciated.

inn regards to this. the BOE screen seems to be less vivid if you had the LG phone before. however i had my S8 on standard or SRGB mode. (maybe it was called basic i cant remember) and to me the colours look fine. i cant say it looks less 'smooth' not sure what that means either and i think you hit the nail on the head. when you start to pixel peep youll see many flaws. even if they arent really there. if you look at the LG display as hard as you have looked at teh BOE, maybe you would have found something else. I know the whole display thing is annoying for the price but i took into account selling my s8 and selling the WAtch GT (which i am using at starting to like) into the price

I think low brightness usage of a screen is a valid scenario which should work properly without green issues. I am occasionally reading ebooks in the dark, at minimum or close to minimum brightness. I had a number of smart phones and they all worked fine with a pretty uniform screen. I am not looking for perfection, but low light performance is a valid usage scenario where smartphone screen have to deliver - especially top tier, expensive flagship models.

I have the LG screen and apart from the greenish tint on the curved sides when viewed in a dark room with grey background (low brightness), I really have no issues during the day when there is normal lighting. I've read several forums with other phone manufactures where this complaint seems to be common, clearly Huawei could have done better QC. For me at least this nuisance isn't enough to return the phone.

Hi The LG is very bad, did you see the anandtech review of the Mate 20 Pro

That makes sense. For me the overall brightness and sharpness is important as I am doing a lot of work outside surveying buildings. This is what I am apparently seeing in my BOE screen, the screen seems to be greyer and less bright than the LG one. But again, it might be an issue with my screen only - that's why I am looking for others' feedback.

Thanks for sharing this review - it's so comprehensive and technical, without being too technical (if that makes sense).

On my 3rd phone with this being first BOE screen.
1st LG screen was utter crap, by the 2nd week at 50% brightness you could see the green around the edges on youtube videos etc... ( I would count that as most peoples use of a phone?)
2nd was much better but was still noticeable while using dark theme and dark backgrounds, which I do a lot. Main issue was I didn't want to wait for it to get worse like the first one.
3rd BOE - Much better screen. It is slightly less vivid but still plenty nice enough for me. Sharpness I have it set to FHD all the time and haven't noticed any issues at all. Only thing I did notice is there is a slight green tint viewed at certain angle, but pretty extreme angle which is unrealistic so doesn't bother me.

I don't think this is an issue that's specific to LG or BOE screens because I had this on my 2nd LG device. I thought it was because I was using YouTube vanced but obviously not. These screens are garbage.

I think OLED screens all have the problem to a certain degree. Just some are worse than others.

Funny, I was sitting in a dark room with the screen set to grey and on the lowest setting and I was thinking, what the **** am I doing??? When would actually be doing this?? Probably never. I think some people are looking so hard for something that they are starting to see things.
I'm not doubting the there probably are some faulty screens out there, I had one right at the start too. But I've had an LG screen for a while now and it kinda looks green round the edges in that unnatural way of grey screen and low light. But I find it 10 time better than the grey washed out screen of the BOE. I had to turn the BOE screen brightness right up if I wanted to read in bed and the auto brightness was unresponsive.
Normal everyday use of the LG screen is 10 time better and the colours are just more vivid. I think I'm going to stick with LG

Sorry but you are dead wrong. This does not remain this way. The LG panel shows the green after a few days even on 50% brightness.
The BOE screen is exactly as bright, clear and sharp as the LG and I know this because I had them side by side.
Don't spread nonsense. LG screen TEN TIMES BETTER? Shame on you.
For your information, Huawei admitted to EE on the phone that all the LG panels were in an early batch, and faulty. Good luck getting help when your LG panel goes bad, and it will.

No need to take that tone. We're all adults here so please don't act like we're back at school. So shame on you!!
It was just my opinion. I have both of them next to each other and there is a difference, I even posted pictures on another thread showing the difference in colour. I'm also not the only person to notice. Plus I've had my LG screen for 3 weeks now and it hasn't got any worse.
I mean jeez all these people getting het up, when it comes down to it, its just a phone.

I have a BOE screen as a replacement for my (slightly) faulty LG screen.
I've had other LG & Samsung OLED (both P-OLED and AM-OLED) screens on phones as well as many LCD screens.
I can honestly say that the BOE screen I now have is at least as bright as *ANY* other OLED screen I've had and pretty much as bright as the SuperBright LCD on my LG G7 Thinq.
The resolution of the BOE screen is also pretty bloody good; certainly no worse than it was on my LG screen'd original Mate 20 Pro.
I don't see any light bleed; only the "usual" colour shift evident on pretty much any OLED screen when viewed at an angle; and for me this phone hardware-wise is now pretty much perfect.

My BOE Screen is great, clear, sharp nice and bright. Except for when the Power Genius app kicks in for Gmail, Chrome and Facebook.

General The Display issue Thread....(color fade, flickering, tints)

Hey guys,
I havent seen a thread related to display issues. In 2 german Forums I found threads about various issues. From Color fade, to overall greenish tint or flickering screens.
Sadly I am very picky with display stuff and my Display isnt perfect either. I mostly use relatively low brigthness settings (around 30-40%) and on dark mode especially the settings menu has a color fade from dark grey to dark blue. This cant be seen on any other color.
Its easy to see in a dark room, the brighter the room the lesser you will notice.
To easier check: use telegram, with its blueish theme its definitely way stronger fading there...
For a phone thats 649€ in germany thats unacceptable for me. My P5 has a slight warmish but perfectly even colored display and thats what I expect from a P6.
What about you? Can anyone check their display if thats a common issue?

Hi,
i have the same issue, also a device from germany.
Even when booting when everything is white, I always have multiple changes between white and blue in the display.
I'm at work, I try to take a picture when I get home.

Please do, Id really be intersted. Sadly we cant do anything about it...

Anybody have the green ish tint on a black screen issue? Seen a few of those floating around as well...

Similar issues with my screen, also from Germany.
My first OLED screen had been with the Galaxy Note 1 and I hated it for its issues. Always bought devices with LCD screens afterwards.
The Pixel 6 is my first OLED phone since and it is having pretty much the same issues my Note had 10 years ago
Great phone so far (Android is still a bit buggy), but the display is quite a disappointment for me personally, at least for brightness levels below ~50%...

Is it just me or are most of these issues regarding the display coming from Germany? Please can people state what country the device was purchased from if they have this issue

Wow @Abnovitas thats really really bad. Sadly till now everyone seems to be from Germany...

I just finished chatting with Google's support.
They are going to replace the phone, but I'm still waiting for their email with instructions.
But first they walked me through some superficial settings (disabling Dark Mode and some accessibility stuff, like Color Inversion...) and then tried to talk it off as a normal property of OLED displays, which I didn't accept to this extent. But hey, that's probably just Google's policy.
Let's see if this was just bad luck in the OLED lottery.

For me its too difficult to take a picture with dark screen. The color change is slightly less than the picture from @man1acc
But i have problems with white color, it is light grey and i have green stripes on white, this is also very very difficult to make a picture.
Here you can see it a bit, but in real life it is much stronger

This is how my display looks like. Quite disappointing, Google has the same problems for years. But the phone itself is very well built, so maybe I will keep it. Bought the phone in Germany.

I have some rainbow effect which is mostly noticeable on white backgrounds. Hard to capture but found it is quite noticeable with an external light source. In this case my monitor. Anyone else have this or more importantly for a RMA, don't have it?

Pixel 6 when on a black background the right side of the display has a green tint shadow effect kinda worrying as it's not present on the left side and seems to only appear on darker backgrounds like when pull notification tab down or in a app (like xda) with black background very noticeable , or is this just standard now for Oled displays it's not the first phone I've noticed this over the years just curious if any pixel 6 owners see similar or should I get it exchange ? Added pic not sure if shows that well though

Not normal. Each pixel is controlled individually.
It maybe hardware or firmware.
Sounds like the display control matrix wasn't designed properly or is defective.
Your screenshot isn't showing it so neither should the display!

Unfortunately not true. If it's an issue with the display, a screenshot should never show it. But it can be visible when a picture of it is taken.
My Pixel 6 (right) was bought first day from the Google Store. I'm in the USA. It has a very strong dirty red tint at the bottom and a garish green at the top. Easily visible at 60-70% brightness and lower. Here it is compared to my Pixel 4a (left), shot on my 3a. Haven't had uniformity issues this bad since my OG Pixel (which got replaced).
Waited to chat with a support rep for an hour, chatted for another hour, and have an RMA device ordered and on the way.

Maybe are cross to dark side lol

That was a joke id never cross to the dark side lol and tint only seems visible when in certain dark mode apps and not actually navigating around the phone xda app is worse lol so don't think hardware issue tbh

At any rate... that's a dud.
Just for giggles and kicks, see if lowering the refresh rate effects that.

My bad too, it wasn't worded as concise as it could have been.

who of you all has the problem with the green rainbow effect on a white background?
