The reasons why I purchased a Tab S 8.4 were its awesome screen quality and high grade processor. For the later, the poor touchwiz optimization and the average gpu led to disappointing results. But well, the screen IS awesome !
Or is it ?
At first, I was truly impressed. But after some web browsing and reading e-books, something felt wrong with the colors homogeneity. On white backgrounds, the right part of the screen in portrait mode would tend towards a yellowish tone, while the left part would tend toward purple tones. Nothing obvious, but quite annoying when noticed.
After trying around with different backgrounds, it become more obvious with certain colors. The one used in settings background for example: The left side of the screen is deep blue, the right part is much lighter.. and greener.
Further investigating the issue, I figured it is most obvious when watched in the darkness and using dark colors: RBG such as R:0, G:10 , B: 20 or even R:20, G:10, B:0
Did anyone else notice similar issues ? Would you guys mind trying to create a R:0, G:10, B:20 (#000A14) background and check the result on your tab S in a low light environment ? On mine, it results in an obvious gradation from dark blue to green.
Attaching some pictures. The rendering is not the best especially in the darkness, but the issue remains clearly visible.
There is something very wrong with your screen. Return it.

I second that, that is not normal
I concur with the others, get it replaced.
AMOLED screens can fail for any number of reasons (pixel death is the main one) , if yours is showing problems get it replaced now rather than live with it and have a more serious problem later.
We've seen this yellow color issue reported by a few others. Looks like Samsung let a few diseased horses out of the barn. I concur with the others. Return it.
Thanks for your feedback, guys.
I'd like to highlight the fact this issue goes completely unnoticed in most scenarios. A friend I showed it on white background didn't notice it at all, in movies/games/pictures I don't see it at all. I only felt it while reading, and even then it was not obvious, just a persistant feeling that led me to further testing.
Only the extremely dark colors seem to be affected, and even then it's only noticeable in the darkness. I will go back to the store tomorow and exchange it for a new one, but I'm wondering if the issue isn't widespread and simply went under the radar as its effect is hardly noticeable in 99.9% of the situations.
Did anyone else check at an homogenous R:0, G:10, B:20 image in the darkness with their tab ?
I personnally used Moon+ Reader's background color settings for testing purpose, pretty easy to set up.
New Tab S, same issue
I changed my Tab S 8.4 today for a brand new one. Same test, same issue: the background is still not homogeneous. The issue is visible in the darkness on dark colors such as the one used for the settings menu, which seems naturally gradated from deep to lighter blue on my screen.
Could someone else test and reproduce the issue on their tab ?
I have tried to reproduce what you're seeing on my 10.5 and honestly I can't. I'm not going to say the white is always 100% pure white but it's close enough. At the same time I'm trying to avoid looking for something that's not there for my Tab.

Maybe you can go into Settings / Accessibility / Vision / Color Adjustments and see if your calibration is off. There is a test there where you arrange tiles by color gradation and it adjusts your screen. I am having none of the issues you mentioned, but my 10.5 Tab also passed that test with no color adjustments required. Give it a try.

Test completed successfully. The calibration is fine, and the issue is not noticeable during the test. The issue is actually not noticeable in most usages, I only see it on homogenous very dark color backgrounds (the 10% darkest colors), and while in a dark environment myself. In most common usages, the screen looks fantastic and flawless.
Unfortunately, I often use my toys in my bed in the darkness. AND I am concerned about a possible defect that would get worse over time.
That said, tests on similar colored backgrounds on other AMOLED screens (PS Vita, Galaxy SII) lead me to think this could be a global issue with AMOLED.

Lol, to those of us with a perverse sense of humor we would refer to that as a hanging curveball.
Whatever issues you are experiencing I would take that over LCD light bleed any day.

Dear Friend. Like you I am very sensible in that point. I have a lot behind me and I can tell you, that homogeneity is something we can not expect from all types of modern displays, except the pro ones with a special function that takes care about this issue. Any screen has such issues, the question is just what type of and the intensity differs. The lower the light in our environment the more sensible our eyes get. The longer we stare into the screen the better we see all color details. Worst case scenario is a totally darkened room. Your eyes won´t get more sensible than in such a situation. Especially AMOLED displays will show the strangest kind of irregularities you would never see normally. I remember the Tab 7.7 -- in a dark room the screen was over and over covered with black circles. Wow ! The Vita shows strange textures instead. It is horrible.
My advice to you would be to start trying to avoid using your tablet or any display in a dark room. Turn a light on, it will be nice for your brain and eyes and you will not see the described things. It´s just a matter of habit, nothing else. You will get used to it and probably feel very well with it. Anyway there will still be the green haze.... Not to talk about the yellowish etc. stuff.
I returned the Tab S for a MiPad and it´s much better, really nice homogeneity (compared to other actual devices).
I had 4-5 iPad Mini Retina and all of them have horrible yellowish/blueish tint.
I had 4 iPad Airs, 3 were horrible in a similar way, now the 4th one is okay, I finally had luck.
I had 2 Galaxy 12.2 - the first one yellowish in a quarter, the second has just a slight, short yellow stripe on the bottom border.
I had a Kindle Fire HD + HDX - both with bad, ugly green spots at borders and corners. Also partially yellowish.
Once I held a Galaxy Tab 3 in my hands that was actually flawless. I was shocked. It never happened again. Was from a classmate.
Today I guess it was a mistake since I could not test in in a home-at-night-environment.
I checked dozens of Tablets in big stores here - guess what I found ???
Look at the iMacs .... Horrible yellowish tint. Horrible. It´s a shame.
I use my Tab S 10.5 in a dark room with some regularity. I've never experienced any of these odd artifacts you guys are discussing. My black screen is just black. Colors look right. White is white. I think its a fallacy to claim that all amoled screens face these issues. The amoled screen on the Tab S is the best most advanced amoled screen ever created. Problems from older devices shouldn't apply here.
Please remember based upon other user input, Samsung did seem to have a run of defective screens on these tabs they put out.
Here's a quick video test taken in a pretty dark room (it's daytime here). As you can see the screen is just black. There is absolutely no reason to avoid viewing your Tab S in a dark room. If you are not seeing the solid black I have demonstrated in this video I suggest exchanging your possibly defective unit.

In my experience 100% of AMOLED displays exhibit this behaviour, i.e. both Tab S 8.4 I've had! The first one (exchanged because of unhappy whites) had it so obviously that it looked like a diagonal gradient fade to one corner. The second tablet shows it as a slightly patchy screen, see attached photo which looks worse than the reality.
This is only visible in a completely dark room with the display set to its darkest (or close to), displaying a very dark image (my photo is of the spec. you mentioned - hence blue/green colour). To show this I needed to use an exposure of about 1 second, if you use less the image will appear black, likewise (probably) if you try to capture it as a video using normal ISO values in camera, the camera won't pick up the background.

All I can say is that is seriously messed up. My screen looks nothing like that and just as pitch black as in my video. Considering black pixels in amoled screens are basically turned off, they should be utterly and completely black and devoid of light. Am I misunderstanding and your picture is of a blue background?
All other dark colors should be solid without strange light effects as well.

It's daytime for me at the moment but yes from memory, if you display an actual black image then it will appear as black, you see this effect when trying to display an image that is almost black, at very low levels of light output the (my!) panel isn't even.
The attached image is R0 G10 B20 and on my PC looks black - it isn't I just used "ColorPic" to check the screen colour and it shows those values.
It's not a big issue but does appear when using in fully dark room with brightness turned down, I notice it in some apps that have very dark background colours (which you'd assume were black and see as such in daylight, but aren't).
Obviously under these circumstances an LCD would appear as a (relatively) bright grey !

OK I'm a bit confused. The image you attached looks either black or very very dark gray on my screen. No color variation at all. Oh well

Same on my tab in daylight, it only appears patchy when in a very dark room with brightness turned right down. Maybe amongst the variations some will be perfect?

Still beats LCD light bleed
Hi all,
Had my Pixel for a few days now and noticed what I thought was a new gradient in the background of posts in the XDA labs app, I checked the screen using one of the grey test colours and found that I'm getting a dark cloud over the bottom right hand side of my screen. I tried taking a photo with my old phone (Moto X Pure) but the camera isn't good enough at low light for it to show up, I'll try and get a photo with my DSLR when I'm back from work later today. In the mean time some quick googling has shown it's very similar to the "Dirty Screen Effect" described here: http://www.rtings.com/tv/tests/picture-quality/gray-uniformity-dirty-screen-effect-dse
Had anyone else noticed this? Do you think Google would RMA it? I've not really been bothered by the blue shift on my device so I'm slightly concerned that I might end up with a worse replacement if I do send it back
Cheers
Michael
It's a tough call, you have to ask yourself if you can live with it or not. Does it show up a lot during normal usage? Or is it just with the XDA labs app and similar applications in a low light setting with your brightness turned to like 0-10%? Or if you can see it at all times regardless of brightness settings you can contact Google tell them of the screen issue and get a RMA. Check out the replacement and compare the blue shift to your current and see if it also has the same issue as your current device. If it's better in both regards send it back, if the blue shift is a bit worse on the one and you can tolerate it and it doesn't have the bad back light uniformity you could keep it. That's what I would do personally, best of luck!
Yes, I have a similar issue. My first device had severe blue tint at any angle and Google would not replace so I returned and and reordered. The second device had only slight blue tint and is not an issue but of course has the uneven grays. The right side of the screen is much darker and there is also a dark spot around the sim tray area on the left side. I sent Google pictures and they are sending a replacement. It's only noticable in low light, looks fine at higher brightness though.
Ah I didn't realize they sent you the replacement first. That makes it a much easier decision. I'll still try and add a photo of it in the OP later today but RMA seems like the best choice. It's noticeable at lower backlight brightness and since it's winter here in the UK now the auto-brightness often drops it down to a level where it is noticeable just in normal daily use.
I get a VERY slight hint of that on a dark gray background at 5-7% brightness in a totally dark room but other than that very specific condition it's uniform otherwise.
The photo as promised unedited straight out of the camera (USB C OTG is neat). It's not quite this bad in person, if you imagine the light grey is the same shade as the dark grey in this image and the dark grey as being almost black then you get the idea, but it does show the difference between the two and it is clearly visible with the naked eye in a dark room.

Woah! Holy crap that's pretty bad. I would RMA that bad boy right away.
Honesly, i don't expect the screen to be yellowish like that, but it is a bit yellowish only if i view it 90 degrees directly. If i view it from the side, the screen shift to blueish colour
Your guide is so useful since i am a new Samsung user, thanks
What phone are you coming from and what other electronic screens do you have around? The S9 is calibrated to 65K (see color temperature) and can appear yellowish if you are used to other screens that defaults to higher color temperature (including most iPhones/iPads). In that scenario there is nothing wrong with the screen and your eyes will get used to the new white pretty quickly.
On the other hand if your screen appears severely yellow compared to other Galaxy S9s' (e.g. check store models) then you probably should 1) get yours replaced from where you bought it, or 2) contact Samsung tech support.
Thanks for your reply, i come from Xiaomi Mi4i, it is cheaper phone by a large margin, but i don't know why the white seems nicer. Oh and i have another question , when i tilt the screen to the side, the white switch to blueish colour and it seems nicer than staring at the phone on 90 degrees, is that sAMOLED thingies ?
As to your latter question, yes that is an AMOLED thing. As to the first, do this simple test: Go to a room with no direct sunlight and no other electronical screens, where you can just look at the phone's screen without distraction. Use the phone for 10 minutes or so @50%+ brightness as you normally would, without worrying about 90 degree tilting. Do your eyes see the whie as yellow? Or have your eye adjusted to the new screen and white now looks white? If the latter, then your screen is likely just fine.
If you want to see what yellow-white looks like, try "Blue Light Filter." That thing does turn the screen yellow. (maybe you have it enabled now and that is why you are seeing yellow? )
---------- Post added at 03:00 AM ---------- Previous post was at 02:38 AM ----------
I have no first-hand experience with the Mi4i, but judging from what I can see in videos its color temperature is at least at 7500K, meaning it has blue-ish white.

hi im having the same problem with my s9 brought it yesterday and youtube videos look horrible discolor yellowish
had that issue with my first S8+. compare it with store models to check. my replacement was much better. now I have the S9, and it's definitely not yellowish. it's such a good white balance actually. so if you're not happy with it, exchange it while you can.
Thanks for all of the reply appreciate it, i check to the store and... turns out it is the same white as mine, still like the bluish white on my former phone. Compared to the note series, the note has better white. I tried to change the screen settings to cool, but it appear greenish. @lopri Thanks for the research on Youtube, respect for the additional research
I already calibrate the screen to cool, to overcome the greenish, i turn down the red and green color, now it is better but still can't resist my old phone blue-ish white.
When watching video on youtube it turns orange-ish, it might be because the video enhancer <- Now this is the problem
Before i got the phone, i have an impression that it would have a very great display... , but now it feels -- only good, but not overwhelmingly great like the review said
"· Record small Shifts in Brightness and Color with Viewing Angle, including White."
http://www.displaymate.com/Galaxy_S9_ShootOut_1s.htm
Adjust the display settings. Put display warmth to the highest then reduce red and green to a quarter.

it's possible the store display also has the same issue. mine is bluish white. I went through the same thing as you with my former S8+, in that even changing settings to cool, didn't make much difference. the replacement I got after confirmed that it was the display itself.
Yep, comparing the S9 and S8 side by side the S9 has a yellow tinted screen. The whites aren't as clear even after adjusting the colour settings.
Man I hate OLED lottery.
Does anyone else have this issue? It's something similar to this:

I have the same effect in original Youtube app. It is just a bad background gradient in the application. Don´t blame the phone....
When I open Messenger with black background and grey status bar at the top of the app in the same brightness level, there is no greenish effect.
I am also having uniformity issues. Very noticeable, unfortunately. As there are no 512GB Ultras available anyway ATM, O will just have to live with it for the moment. Maybe I get used to it...

mm weird, I see it in every single app with dark grey background, even in settings (w/Dark mode on), the bleeding is a lot bigger from the top right corner.
EDIT: Just checked the messenger app (FB messenger) and background is completely black so most pixels are off except for the letters and gray search bar but bleeding wouldn't be noticeable.

I've just checked it with Gmail since it is also a Google application and you can notice the bleed when the lights in the room are turned on and I try to cover the top of the phone to see it. After turning the lights off, whole app is equally gray so in my opinion it is just an optical illusion. If I recall well the AMOLED displays use some kind of dimming (tinkering with the frequency) in order to reach a lower point of the brightness that is not noticeable for human eye. Probably this can be seen when covering a gray part of Google apps in a room that has another not so bright light source.

I made a picture. It is showing a 5% gray test pic and supposed to be uniform. It is easy to see and I was kind of shocked when instantly noticing it the first time I was using it in the dark. Settings and many parts of the dark one UI are using grays in that range.
Anybody else? If it is rare, it will be worth pushing for an exchange.

I did the same test, I'm attaching a picture of my Note 10+ and the S20 Ultra side by side. Uniformity seems a lot better on the note 10+, however on white background the Note 10+ turns more red when I slightly tilt it while the S20 Ultra seems to shift colors a lot less and still white overall.
Still not sure if it's worth the hassle to return.
Ok, the fact, that it looks very much like mine can be good and bad ?
Could you please check, if is different at 60Hz? For me, it is clearly different.

Oh wow, you're right! I set it to 60 hz and QHD+ and uniformity on the gray test got noticeable better, still some green on top right corner and around the punch hole but noticeable less. I love reaaally 120 hz during normal use though.
Thanks for confirming, same here. I wonder, if this is something, that can be fixed in software... And if the rumoured 'dynamic refresh raze' update might change things.
Could please note people check their Ultras displays?
Same here with my s20 more visible at 12hz refresh rate with dark theme
Damn it, ok, then I really hope that it is fixable... Weird.
I am using smiled displays since Symbian Nokias, never had one, where I noticed it so much.
I remember all the Mate 20 Pros with LG screen had this issue buy way worse in some cases
https://www.google.com/search?q=mat...JtXpfSDsL9sQXomrbgDQ&rlz=1C1CHBF_enUS731US731
In some cases they were normal during the first days but the problem evolved until the display was unsusable in low light conditions, hope the same won't happen to our phone during the next weeks.
yeah I don`t have this issue I did the screen test in Gmail and download the app that does all the different colors including gray, at the lowest brightness and at other levels of brightness at 120hz its all uniform.

Mine is most noticeable at around 35-40% brightness and with 120 hz but still noticeable with 60 hz while on the note 10+ I can't see any green at all at any level of brightness. I think it's a quality issue and variation of OLED screens but not sure if it would count as "defective". Samsung doesn't do exchanges so it would be a pain to return everything and recorder without the promotions and reservation/pre-order credits. Ugh not sure what to do yet.
EDIT: Btw I tested with gmail and didn't notice the green in the app since it's light gray but as soon as I drop down the notification panel (w/dark mode on) the green is immediately noticeable. It's only with very dark gray that lookd almost black which is what Samsung use for all their apps (settings, calculator, messages, etc.) when dark mode is on. I wish they used true black so pixels were completely off like with facebook messenger.
I am also unsure what to do. I have to say, however, that this is the device that gives me the most uncertainty ever. For this opportunity price I want a good to perfect display. @vwite Don't you think that the dark grays are too bright as well? It wouldn't be so visible otherwhise. I also sent my picture to the 'write the CEO' address and a pledge to be aware of the issue:
https://www.samsung.com/uk/info/contactus/email-the-ceo/ (example: UK)
I will try checking in a store, which will be totally hard because of the light there. Maybe I will just order another one... Or a plus ?
Made another picture 'for the CEO' :silly: and will also attach the source image I showed on screen. To replicate:
- 25% brightness
- Show 5% picture in a dark room
- made picture with an S10+ on full auto

Thanks! Please let me know what they say.
Actually I ordered an S20+ now and will most likely just give the Ultra back in the first 2 weeks. Yes, it is a pain, but I really can not stand the screen as is. I am even putting it in its box before I have the plus and using my S10+ in the meantime - the green tint is driving me a little nuts.
I am having a hard time justifying the thickness and weight for a feature I hardly use (amazing zoom) while having an inferior main camera at the same time (focus issues).
i noticed this issue too on my 20+
it seems to be worse some days less bad other days
it also is very dependable on how much ambient light is around - eg is much more noticeable in dark rooms
and yes is an issue with Samsung dark mode that isn't true black but some dark greyish
other then this - all other colours look amazing = so not sure if the screen itself is defective
I do hope there will be a software update that will fix this or make it less visible
Hello, I've noticed that when I use my phone in night mode I can see green areas on the screen. Are there other people in my case?
No on mine so far. Black is black no greenish.
is see this too sometimes esp at night when its dark in the room with no other lights - in the day when its brighter is not visible
it does seem to be an issue with some backgrounds as i noticed in apps where the background is black (not dark grey or greysh) this isnt visible
so not sure whats going on - but i didnt had this issue with the s10 .....

Yes, I have the same problem, it comes from the screen according to what I read on some forums. Some OLED screen have problems. I think I'm going to get it exchanged.
no issues so far with mine s20+ (exynos variant), however if i were you i would seek to get replacement

Screen sorry ^^
ok but how do you explain that its only visible sometimes and then sometimes is not?
and is only showing on grey backgrounds etc
like now i have the phone in my hand and is looking ok
the best place to test is in the samsung daily or SMS app - the top part of the app thats meant to be black was sometimes showing more like greyish - now is proper black again?
like i said it seems to be dependent on the ambient light - i wouldnt want to replace the phone if its not an actual issue esp since it took me a whole day to get my stuff transferred and setup

Oled is known for reduced quality the lower brightness you go.
But all units will have varied levels of tints etc
In my case..
Unfortunately, yes. Also, it is more noticeable at 120Hz.
There is a thread about that in the Ultra section:
https://forum.xda-developers.com/galaxy-s20-ultra/help/green-tint-dark-background-low-t4065621
I also tried to get people with that problem in the S20+ section:
https://forum.xda-developers.com/galaxy-s20-plus/help/s20-ultra-oled-bad-uniformity-bright-t4067051
It is rather horrible and i noticed it right away the first time I used it in the dark. I think it can not really be fixed in Software, but it can be probably made less noticeable, as 120Hz is making it worse.
I wrote an 'email to the CEO' about that here:

If its same as below thread...Welcome to OLED!
Colour blending (blacks) problem
https://forum.xda-developers.com/galaxy-s9-plus/help/colour-blending-blacks-problem-t3765385
Had this on my S9+ and S10. Nothing can be done about it.
Using OLED since 2010. Starting with Symbian Nokias, Windows Phone Nokias and switching over with the S8+ - OLED only.
I suppose - never had a display that bad in this regard. At least never noticed it that bad right away. The upper right corner is almost always showing a green tint.
But I am glad, if it is not too widespread - then the S20+ I ordered will probably be fine.
in your case what?
Pardon me?

sorry it was for an earlier post with a screenshot of a call in russian
Hi,
Just attached a picture of my screen with adaptive brightness with low light with screen at 120Hz.
At 60Hz the screen is even, at least almost even.
What is your opinion?
Thank you in advance.
Report it to Samsung, probably get it exchanged, if possible and it really bugs you.
I gave back the ultra because it was too much green tint. The plus has it as well, not as bad as the ultra.
