Uneven black levels - Samsung Galaxy Tab S6 Questions & Answers

Anyone else having this issue? When I switch to the dark mode it's obvious the black level from one corner to the other is not the same.
A black saturation test clearly shows the bottom row visible when the device is rotated one way and then not visible the other way.
Anyone else getting this? I'm going to ask for a replacement.

Jup i have the same

Damn, that's almost exactly the same.
I just got a full refund for mine as the shop I bought it from had no stock for a replacement. Another one on the way from another retailer, hoping the display is in better shape.
The quality control on these appears to be a bit crap.

OneUI uses dark grey on the Tab S and Note10... There are many, if not infinite variations of grey that approach black. I do art, so it's easy to notice that #000000 was substituted.
SD_black is black, OneUI simply has a dark mode. Also black cannot be uneven on OLED, because black refers to an off state.

You're just splitting hairs.
Black can appear uneven on defective OLED displays. If you use a black saturation or black clipping test you can clearly see with the tablet or phone rotated one way that the bottom row is barely visible (which is normal), but rotate it another way and suddenly they're all clearly visible, they're only visible because that part of display is defective.
I have OneUI on my phone as well, there is no visible banding and black/gray levels (whatever you want to call them) are uniform. If you're seeing any variation then you got a bad display and you should get it replaced.

Similar here. But mainly noticeable in very low brightness especially with night mode on

With which app do you test it?

Display tester, first match on the play store. Find the black saturation test
Or you can use something like the below, loads of similar tests available on the Play Store or online.
https://www.avforums.com/threads/ho...el-on-oled.2204710/#lg=thread-2204710&slide=0

Replacement arrived today and it's even worse than the first one, instead of one corner it's right down the centre of the display.
Also found an easier way to highlight the issue, using the image tester select the burn in test and move all the sliders to the left, this should give you black. Then slowly move the green slider over, you'll notice some parts of the display become green when the rest remains black, at least up-to a certain point. Took the image below in good lighting.

The Amoled lottery. I had to go through many returns before I got a Tab S3 that didn't have unacceptable display uniformity and things don't seem to have improved a lot since then.
I guess that it's cheaper for Samsung to deal with the returns of customers who notice and care about this than simply having better quality control in the first place. Reviewers of course get cherry-picked samples so the quality of the display can be praised to high heaven.
Really makes me think twice about even considering upgrading though...

same here, You say they change it under warranty?

Is your display like that for every image with that gray scale? Or is it just elements of the UI settings, dialer, contacts etc when you have dark mode enabled?

I'm doing this through Amazon,
I did call Samsung support hoping to speak with someone and they basically just said take it to a Samsung store, I'd rather not waste time with that, they'll just pretend they've never seen the issue before and send me back to retalier for a replacement.

you can even see it on on xda black theme.
But since this is a common issue maybe manufacturing level, I rather leave it like this, because I do not want to end up with an even worse one.

hi
hours ago i found that when a blank tab is opened in samsung internet (i am using dark mode in system as well as the samsung browser) i could see the uneven black on the screen. i tried to rotate it but still the uneven black was there on the left and right hand sides in landscape mode, and on the top and bottom after i rotated it. so it should not be the ui or one ui problem
i remembered i have read this post so i revisit it and found many of you have the same problem. when i bought this tablet i have check via *#0*# to see how the black was and it's perfect. i also checked with *#0*# before replying to this post and the black was perfect too!
i am too wondering what could be the problem. i think it could be the dark mode which does not use true black (pixel off) in fact

Yeah, It's not the dark mode, this issue effects everything.
If it was just One UI I could ignore it, but sadly it's not. Essentially you have different parts of the display clipping at different black levels, even the sections that are relatively good still look patchy.
Samsung screwed us all but it's OK because it's not a popular product so nobody cares, prime example of how useless reviewers are as well because none of them picked up on it, cherry picked parts from Samsung probably.

Screen problem: slightly visible moire-effect like pattern

I bought this phone 2 days ago, new, sealed, free from contract, and so far I love everything about it, except for this problem which I have found only today. I guess It was all the first excitement keeping me to notice earlier.
Like the thread's title says, it's like a perfect pattern across the screen, from edge to edge, consisting in perfect parallel 10-degrees-from-horizontal-oblique stripes. They are very very subtle and only visible on light backgrounds and more from looking from the upper part of the screen down.
Do not confuse them with the pixels matrix, whose density, by the way, is great. They are all right, and the effect described above seems to appear on a layer which is on top of those pixels.
To make an almost perfect comparison, this effect looks almost like the striped background from market.android.com (as seen on a computer), but with more subtle greish on white stripes inclined from right to left, and only like 10 degrees oblique from the horizontal. That is what's making me curious, why is that pattern oblique? If it were straight horizontals or verticals I would have confused them with the pixels arrays, and it would have been bearable. But like they are I can't stop but notice this pattern every time and it annoys me a lot! In GMail, Browser etc... all the apps with plain backgrounds...
It wouldn't appear on any close picture I tried to take, and I guess filming for you to see it isn't a good idea either, because you won't notice it. It's only visible with the naked eye, at a distance closer than 30 cm from the screen. It isn't also a problem of my eyes, because my wife is noticing it too.
Thank for any shared thought.

Much better to send you're mobile to the store were you bought it. because as what i have know the problem is the LCD. that is what they called wire stripe or ribbon.... maybe that is the problem. Try it, there is noting to lose.....
I see that too, only on light (white) backgrounds. I thinks it's normal, you may ask your local Sony Ericsson customer service or a phone shop, but I don't think this is a production fault.
On a dark blackground it is purely invisible.
Try it with and without the Bravia engine enabled.

sdk16420, thanks for sharing this, It is somehow a relief for me to know I'm not alone in this. Yet, I'll wait until next week to see if I can find more explanations, and then maybe I'll return it for a replace. It's especially bad for me, as I waited a lot to receive the silver one (a week or so), and I don't know if I can find another.

It doesn't depend on Bravia Engine, unfortunately. It was also the first thing that came into my mind, tried it several times, even with deactivating and rebooting, but the effect is persistent.
Again, it's only visible on light backgrounds, especially white and large ones (browser, gmail, etc). If you read this, please check yours also find some time to post a reply with the result. I would be very grateful.
Thanks!
I have the blue model but i can barely see that pattern with a screen flashlight (on full white) and i don't find it annoying at all in daily use of the phone.
You can check the screen from a new phone in a shop, to see if it looks like yours ... or you have a eagle eye
PS
check softpedia also
I think I can see what you're talking about on my Red Neo but only if I max the screen brightness and look really closesly (like practically inserting the Neo into my eye). 99.99% of the time I don't notice a thing.
I just followed your description and found the same with my neo, so I think it the LCD design. Not an issue to me indeed.
Does anyone have another phone model (e.g. Samsung, HTC) with a LCD touchscreen? Is it also visible on other phones?

I have a Samsung Galaxy S with SAMOLED, a HTC Desire with S-LCD and an Asus Transformer with IPS LCD, and they all have better screens. The Desire's is the most problem free, whereas the Galaxy S has problems with screen burn-in (or image retention, like some are identifying it, but for me it's still like the old good plasma screen burn-in ), and the Transformer's has light bleeding. But, like I said, when put aside, the Neo's looks the worst.
I don't know if you noticed it already, but it comes with another "feature" that is so annoying: it stays always on auto brightness regardless of the custom level set, maxing that automation on that custom level. It's so annoying, cause it's always too dark for me, and being a "feature" it doesn't have also a switch for that. At least it has for Bravia....

When I put brightness on 100%, and hold my finger on the light sensor, I don't see the screen getting darker. What does annoy me is that you can't make the brightness less than about 30%. I use widgetsoid for brightness adjustment, and the screen will only become darker than 30% if I hold my finger on top of the sensor. That sucks. I I want to sacve energy, I have to hold my hand there, while using the phone.
I don't see why people need the brightness that high anyways, aside from in some games with small hard to see details I'm perfectly fine with my brightness set at just 30% or even just 20%...heck I can still use the phone when the brightness is completely off though that does get a little hard to see everything.

I use it a lot outside, and its sunlight legibility isn't as good as SAMOLEDs or others, but that I knew from reviews before the buy. If it wasn't for the problem in this thread, I wouldn't be so harsh on it.
LE I se new posters here. Do you noticed the problem described in the first post? Does it bother you?

Backlight uniformity?

I love my Xperia Z4 Tablet. However the backlight is noticeably dim on the bottom (when in the default landscape position) or the left hand side when in portrait (volume/power button facing up). It is most noticeable in portrait mode when there is a white background (Kindle, Chrome and Instagram most notably). I am willing to live with this issue, but was wondering if anyone else is seeing any issues?
For the price I paid, it would be nice to have uniform backlighting. But I am worried it could be worse on another unit. Expansys has offered me an exchange or refund but there is a delay in availability now that the first lot has sold out.
No problems with mine
I am sending mine back for an exchange. I miss it already
Now I noticed that too. The difference is really small, but it's there.

Hopefully my replacement isn't any worse than the one I just sent back. It was as bad as I could handle.
Interesting, the same with my tablet - seems to be a general problem
I don't know if I should return and change the tablet...
can you make a picture for us? I dont know what you mean? my backlight is perfect - no bleeding and no clouding )
I'm sorry, but it was not possible to make a picture where you can see this.
However I can only see it on white backgrounds - the first centimeter is slightly grayish...

It is not a hardware problem. I see the band only when the bottom menu appears. It looks like the transperancy issue with that menu layer.
Mine looks fine, just hope it is not something my eyes just don't notice, but others do.

No, I think it is a hardware problem - if I turn the tablet from landscape to portrait mode, white backgrounds are gray on the left. Btw for me it's only visible in portrait mode - in landscape mode the menu bar on the bottom is usually black or transparent...
It is definitely a hardware problem and it sounds like the backlight is weaker on several units on the bottom (when in landscape) or left hand side (when in portrait with power button facing up). It is a shame as it is very distracting to read on anything that doesn't have a dark or black background in portrait. Still waiting for my replacement unit As long as the replacement isn't worse, I will likely live with it as I really enjoyed (and miss) the tablet.

Try anything with an all white background. If you open Chrome with no web pages loaded and the new tab page up or Kindle with a white background and hold the tablet in portrait, you might see uneven backlighting on your left or right sides depending on the orientation.
Backlight direction is notable
Got my Z4 tablet yesterday. After reading some issues with the backlight I checked this at my device and can see there is a notable uniformity.
If you hold the device with power button upside, then one can see a thin bright line from the backlight LEDs on the left side, while the opposite screen edge is slightly darker.
It looks like the screen is only backlighted from one side. For the normal usage it is not really annoying, but it is there and you would see it, if you take attention for the issue.
Do other Z4 owners have the same effect?

I have the impression my Amazon Z4T packages was already a replacement from someone else. The box made used look, some scratches and one corner had a ditch.
It wasn't sealed in any way. The charge adapter cable looked out of its the small box. The screen protection layer made the impression it was reattached, a lot of air bubbles were included.
Can someone describe how he found the delivery when unboxing it?
Was it sealed?
I also consider a replacement, if the screen issue is not a general construction feature.
Oddly enough, I purchased mine from another supplier, and also felt the item had been handled if not used. USB cable was out of wrapping and screen protector had signs of being removed and re-applied. I received mine the day after they were available for sale. I am hoping my replacement looks like new and has minimal or no backlight uniformity issues.

Hopefully you get it soon and can report here the condition of the replacement.
I have 14 days left to send it back to Amazon for free.
Please also describe how it was packaged.
Are there any seals or blister foil?
I can't believe Sony delivers an open package to retail stores.
Unboxing videos on Youtube don't show this clearly.
Thanks in advance.

For me:
Not sealed.
Box in perfect condition.
Screen protector had a few bubbles, but not that many.
It was perfectly even on the tablet, edges protector = edges tablet.
Charge cable was in box, but it was wound a bit loopsided. But I think it more likely that it came that way - besides, how many people do even need those cables nowadays? Even if they need them, they likely will not use them when trying the tablet out.
Charge of 65%
Tablet itself:
I couldn't see a backlight uniformity issue, tried it with a white background with 100% luminosity in a dark room. Compared to the Z1 Tablet the screen looks a LOT dimmer in the dark, but I suspect that is more because the Z4 has some auto-dim function there. In bright light the Z4 screen looks slightly brighter.
What I noticed is that the speakers produce a fair amount of white noise. At 10% it is very noticeable, at 50% I do not hear it unless it is a very silent scene and I am concentrating on it. Somewhat annoying and IMO not something a tablet in that price range should have, but not annoying enough for me to play replacement bingo.
My seller is out of stock with a new batch due next week. I'll let you know when it comes. From what I can tell, Sony products are never fully sealed.

Yellowish / Warm screen on the international S9 plus?

I have the Indian version/ exynos version of the S9 plus, and the screen seems to be overtly warm or yellow throughout. The whites are mildly yellow instead of white.
I tried everything. Changed the screen mode from adaptive to basic to cinema to photos. Still warm. I tried reducing the reds also. Still a bit yellow. Is this a problem with other users as well? Anyone can help me with this? Do I need to send it for replacement?
I've seen a lot of devices in stores (UK) and most of them -but not all- have a cool white temperature.
As with all panels, unfortunately this boils down to a lottery. I'd suggest you try to replace your phone if you're not happy with it and hope for a better white balance on the next one.
My first S9+ had cool whites but uniformity issues (left side cooler than right side) along with black crush. My 2nd unit has good uniformity, cool whites but sadly still black crush.
Actually it might be worth checking the thread about the colour blending https://forum.xda-developers.com/galaxy-s9-plus/help/colour-blending-blacks-problem-t3765385 and see if your device has this problem before you make a decision. If you like watching video on your device, it is a much more serious issue than white balance.

Thanks for the suggestion. I went through it and posted it there as well. I don't have the black crush problem (lucky me i guess?), but this yellow tint is unbearable. I think I'll go to the store and show it to them.
Hi,
This is a stupid question (maybe): don't you have the blue light filter on, have you?

I have the same exact issue. I have the blue light filter off, maximum brightness on, and basic display rather than adaptive, and still yellowish. When it initially starts up the screen is white, and then the Samsung software loads and it turns yellow. I factor reset it, same thing happens. Did you find a fix? I have been spending hours trying to fix this issue with zero luck.
same problem here exynos variant. yellowish when facing directly on screen but when viewed from different angle i got better color. hope we will get an answer to this problem of ours.
I have some problem, got it from Dubai.
i think mine is more serious. Whole screen is Yellowish
So this is on the Snapdragon models?
Here's an example of an unlocked US S9+ that I posted in the black crush thred.
The top of the screen was significantly brighter / warmer than the bottom even during the day. I ended up exchanging this device for another with the same problem. I gamble in the amoled lottery through a different retailer.

Hi Guys
I was Having exactly the same problem, but then I start thinking backwards and I realize that he problem start happening after I Activate night light for google ebooks, then I when there and deactivate night light and it fix my problem, and that is the reason why it affects your phone even if you reset the phone to fabric because the ebook night light is on google not on the phone inself.
Mine seems to be cool white, compared it to my s8
YELLOW TINT SAMSUNG S9+ EXYNOS 128gb Titanium Grey
Hey guys im living in saudi arabia we have the samsung exynos version
first and foremost the display is frighgin amazing nothing to say about that, next the whites, allthe background with white screen (csetting chrome youtube all bckgrnds ) everywhere its like a coffe dipped ( maybe a bit too much) but in general the white does not feel like its supposed to
its like the warm setting comes in default but
they had the same issues with s8 & s8+ last year the store guy told me "samsung had fixed it" :::::bull****.
there really is this yellow tint problem this is exactly what happened to me:
1. 13/04/18 bought the s9+ 128gb titanium grey from store
2.opened the box two days later (i know) was busy.
3.the moment i switched on it started troubling me going through the initial settings in mid brightness , i said to myself might be ready after setting up. Then when the phone swtiched on i forgot about it all coz the screen is beautiful you gotta admit that
anyways after sometime going through the ssetting i found the yellow tint i was friggin irritating.
4.i played a lot with the display settings
adpative display
WQHD+
yelloww tint
then went into the advanced made some rgb changes it is possible to get somewhat of a pure white screen but stilll it is not perfect
so on
5.18/04/18 i went back to the store showed em the problem u know what they said
"I'm the first one reporting such a complaint" anyways he said hell compare it with a piece , they got a s9 at first switched on and fish it had the same yellow tint. i had lost all hope
i told em compare it with the same model so they got another one black s9+ switched it on and "hurray" the screen was pure white( cool setting white) and they wer dumbstruck he called the supervisors they all saw the problem, they reset both the phones nothing anyway i got a replacement by closing time. took home the new s9+ grey
6. opened it " fish" it was the same yellow tint . anyways the store told me if i was facing the same issue again to come back.
so will update you guys after
But this is manufacturing issue i think go at once claim the warranty
we gotta shed come light on this topic becoz this being a new phone everyone isnt aware of it samsung should at once rectify this **** if a problem.
I am not an international user, but I would have to agree with the people in this thread who say that screen balance really is a lottery with the way that Samsung manufacturers AMOLED displays. The displays are produced in big sheets that some refer to as 'wafers' with each individual display punched out of that sheet. The closer your display was punched from the center of the sheet. The better quality/balance it will have. The displays punched out from the edges of the sheets are more likely to have discoloration, and other anomalies. With that being said, there is truly no such thing as a 'perfect' AMOLED display. The most you can hope for is one that is more or less within the tolerable limits of your expectations. I have a T-Mobile Snapdragon S9+ with a manufacture date placing it closer to what was probably the beginning of the second production wave after the initial pre-release wave and my display is pretty good. Little warmer than I am comfortable with but uniform in balance, very little shift, no crushing.
i have an international DUOS (dual sim) version of the G965F Exynos, and when compared with demo phones here in uk and a friends s9+ from o2 (all same settings) its more yellow ... a bit annoyed but its still a nice screen ...
same thing here in my country, all of the display units have cooler displays than my retail s9+ and i don't consider that to be an issue
i'm almost completely sure they tweak those display units, so they look better than the retail version.. after all, they need something to show off with, something that will attract the customers and what's better than the display? i mean, that's the first thing users see and interact the most with, so it kinda makes sense.. moreover, you cannot even open the display settings, because it crashes immediately after you tap on it

Funny that you said that because I've went through literally 6 phones and 3 of them had perfect whites. The other 3 were yellowish.
Thanks that solved the problem.

S9 + yellow tint on screen FIX
Hello! I found a solution to your problem! I also have s9 +.. and every time i was recording in QHD or UHD.. and then try to see what i had recorded..my screen was turning yellow with no reason.. like the blue light filter was on..even if this one is allways OFF. . . So i found out how to fix that and have no more problems after. Go to Settings - ACCESSIBILITY - VISION - And then close to the buttom you will see : COLOR ADJUSTMENT... You click o that, then turn this ON, and then go and choose :TRITAN ( blue and yellow ) or PERSONAL ... and this is it!
I think this problem is a software bug. I had done a hard reset etc.. but my problem wasn't fixed until i had done those settings on color adjustment!
HIT THE THANKS BUTTON IF YOU FOUND THIS USEFULL! THANK YOU
Here is the method used, posted by me on youtube:

Hi Guys
I was Having exactly the same problem, but then I start thinking backwards and I realize that he problem start happening after I Activate night light for google ebooks, then I when there and deactivate night light and it fix my problem, and that is the reason why it affects your phone even if you reset the phone to fabric because the ebook night light is on google not on the phone inself.

Thanks for this tip, it fixed my yellowish screen instantly. I had turned night light on in Google Play books a week or so ago and forgot about it, but ever since my screen has been too warm and yellow and general Android Settings did not help. Problem solved as soon as I turned night light off in Play Books. Turning off blue light in general settings does not work.

Mediapad M5 pro panel brightness white background

Does any tablet owner here of M5 or same family tablet, has noticed if one of your display has an edge or sideline that is slightly slightly darker, during using a fully white background?
On my m5 Pro I've noticed that with a fully white backgroud, I do have an edge, close to the left bottom corner (holding the tablet horizontally) that is slightly gray rather than the right side. Off course that: if I'm rotating it, then it Will happear to the top instead.
If you don't stay there and looking at it for a minute, you don't notice it. But if you look at it and compare to the rest of the screen or other side, then you'll see this small difference.
Do you have same issue? Does it is an IPS display issue?
Ah! It makes it only with the White. Only the White. Other colors comparisions are fine.
Looking videos, pictures or anything else that does not push the screen to a very high density white in that side, it's fine.
You can try to see if you're having the same of opening the cleaning chache program, where there is a lot of White all around the screen. There you can watch side by side and every corner... and you can try too see if somewhere do you have a slightly white difference compared to the rest.
But as said above. Only white make this.
Videos, pictures with same colors side to side are fine. It's all about the White.
I've contacted the Huawei assistance trough Phone and they said that is normal and panels might do this, and if in doubt, I'm free to go to the Local official technical assistance in my town to have a confirm for it .
So I've done that! I've moved to the Local technical assistance and the technician told me that it might happens and it is not worthy of a repair, because changing panel might not solve the problem as this slightly slightly brightning difference might show on another side. Has more sense to wait if in these 2 years something going worse and repair it over warranty.
It's hard to see this difference of White brightness, and I've noticed that just because I'm a really fussy guy and ... off course I don't spend my time on surfing on the menus. It's also a post to understand it these kind of IPS panels may encount these issues.
Anyone here is experiencing this thing? Or are you watching all the sides of your tablet to see if do you have it aswell? :laugh:
It's called uneven brightness, and reading notebookcheck's review said that it is above average. Seems you have received a dud, but it's likely within tolerance im afraid.

Are you sure It's a dud? In a FB group a guy said that he's even worse on his 8.4 because he has it all over the edges . And on a previous M3 he got, there was an even worse side with less brightness. And so He returned the tablet.
In my case, it's so soft that you don't notice it at all. You do have to search for it. And it happens only with the White.
It the technician in the store told me it's not worth a replace the panel, this slightly brightness might happpen and same issue might happen in another side, nobody knows. I wish to beleive him . Why He would had lied to me?
Anyway I've read the m5 review and they are showing the characteristic of the brightness all over the display. Yea, it is seems a trait of it, and a 0,25 cd/m2 is barely perceivable.
What's your opinion?

my M5 is perfect, no noticeable differences in brightness anywhere. Notebookcheck said that the 8 in model has poorer display anyway.
If it's not noticeable in normal use then it's fine.

Nah...exept The White background, it's ok on all use.
But as said above, if I do watch that edge to try to catch the eye to find this difference.
Technician said it's ok. Hope it is. I just want to know if anyone experienced this with this model or any other tablet with IPS display

Is there any reliable software for Android to do the same thing done by notebookcheck and testing the brightness? Like this:
I've checked that one on playstore, but I did not find nothing.
Any suggestion?

You need something that can detect the brightness, usually expensive hardware that connects to a windows machine. I think they start at around $500 or so. You could rent one i suppose. (if you could find somewhere or someone!).
But yeah it needs hardware.

What did you decide? I have one side that is darker or M5 10.8, not a pro version.
Should I try to replace it? It does not bother me much and I read here that there are more units, that come with more darker sides/edges.

The problem for me it's just a little and not worth a change for defect.
Because a repairing stores told me that quite always somewhere that little little darker side happear. It's not guarranteed that with a replacement it would not happear elsewhere. It's happening only with the White. Normal use the tablet is fine.
It's an issue of the IPS display, expecially large displays. That's Why i love the AMOLED all the way.
Technician said it's not for a change/repair, exept if it is gonna go worse.
So I'll keep it. Does your problem is so noticeable?

It is, the whole left side is darker, so I contacted for replacement. Amazon was very helpful and the replacement is coming to me. Hope that unit will be be without darker sides.
Thanks for help.

Did you had this issues also with other colors? If you were watching a movie or working on a picture was noticeable?
For me it's only the White, but you do have to look for it. It's same issues that have low/mid ranged TVs.
Not worth a change or a repair. Because it can ne elsewhere.
Does it is the same for you?
Keep us updated.

Yes, there was also a problem with other brighter colors. It was noticable only when browsing, but that's mainly what I do with a tablet. After a while I started searching for that darker side in various apps/colors, instead of enjoying a tablet.
Today I got a replacement. The screen looks more or less fine on the sides/edges both with white and other colors.
my m5 pro 10.8 is perfectly in balance.
iv´e tested with a white fullscreen wallpaper on max. brightness. everything is ok.
also other colors are fine.
...
every M5 screen has it. I had 3 pieces, each one had a near the status bar (battery, hour) visible only at a sharp angle. If you do not see it, you look at it badly. I stayed with the first copy. These two still had dead pixels. This is the construction of ips.
yeah i have no issues on mine, full brightness and looking from sharp angles doesn't make much difference at all. Slight brightness changes maybe, but same happens to any screen.

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
