Just got my VZW galaxy nexus, and im loving it so far, but have noticed something odd: toward the top of the screen (about 1/4 of the way down from the top) there seems to be a very slight green tint, noticeable only when looking at a dark background (like the settings menu).
It's kind of hard to explain, does anyone else have something similar on their phones? Is this normal for amoled screens or should I ask for a replacement phone?
i believe it has to do with it being a pentile screen... well, 'HD' pentile, but still..
i'd say if you try an exchange, make sure you the test the other in store first.
can anyone with a galaxy nexus please post a photo of their phone on the settings menu? (scroll all the way down)

Pretty sure the setting menu is a background gradient with an intended color shift.
But yeah, mine has a blueish/greenish hue if I tilt the phone away or towards me in portrait mode. Straight-on, I don't notice anything.
yeah i am talking about viewing straight on
mine has this greenish tint slightly at the top right screen...
that settings menu then scroll all the way down is normal.. the color is not as dark as the top. I'm seeing greenish tint when on white background
I have a very light greenish tint on the right side of the phone on white backgrounds with text when at low/automatic brightness. The green goes away when I bump brightness to 40%+.
Did you try that?
Oddly, when I ran pixel checker, the pure white background has no green tint to it at all.
Yeah, at low brightness I see a tint/haze but at full brightness, everything looks beautiful.
Welcome to the world of pentile.
I see the same green tint on my screen. I thought it was normal, but I compared it to another unit today and saw that my display was both dimmer at the same brightness level and had a greenish cast and different color temperature than the unit I was comparing it to. I'm not sure if this is within the normal variance for these displays, but my phone certainly looks worse to me than the one I compared it to.
Both units also showed a green/blue tint when viewed off axis but with greater discoloration on mine. The second unit showed almost no discernible tint when viewing a white screen straight on unlike mine.

i have the same problem. Sometimes (usually after a power down and restart) my entire screen is very dark and has a, very obvious, green tint to it. I compared my phone to my girlfriends at the same display setting and the tint is very obvious (especially when i'm viewing menu, text messages, browser). When i adjust the brightness it seems to make it less obvious, but still there. However after certain power down and restart this "green tint" seems to 'go away' only to either gradually re-appear or just happen when my phone self adjusts to "automatic brightness" setting.
p.s. my phone also, had another minor issue of random re-start when listening to music (via google music) and adjusting the sound effects option. After that restart my phones display was significantly tinted and dark. Weird, Either way getting a replacement unit tomorrow.
Mine has a very slight green tint on the left hand side of the screen when at the lowest brightness and viewing a white background.
I normally have the brightness bumped up a bit, but it still bugs me when I have it low
EDIT: Checked pixel checker, has the green tint. I can definitely see it on the keyboard as I'm typing this though
I took my unit in to Verizon today for an exchange. New one doesn't have as significant of color shifting or banding issues.

yeah i got mine replaced the next day, all good now. No green tint, reduced banding, and much better viewing angles (the first one heavily tinted green or pink colors when viewing it from the right or left side, respectively)
Alright, got a replacement today.
No green tint that I can see, almost no banding and the colors don't change like, at all when I tilt the phone.
Now my nexus truly is perfect

Sorry, I find this very hard to believe. *ALL* pentile AMOLEDs change colours like crazy when you look at them at a sharp angle. It's a characteristic trait of this kind of display.
Pics from various angles or it didn't happen. ;-)

That's nothing to do with the Pentile Matrix! Definitely a defective screen, return it to the store and ask for a warranty replacement. The 'banding' is more to do with the AMOLED screen technology rather than the Pentile, as it was present on my SGS2, but is generally only visible under certain conditions (background colour/brightness).
Regards.
Is it visible on colors other than grey?
Sure, on blue background too,sometimes on white.(poarws photo with blue background) It depends on brightness.
More visible at white background with high brightnes.
More visible at blue and grey background with lower brightnes.
It does have to do with the Amoled technology, but I doubt it's a defective display. You can try to exchange it to see if it really is defective or not.
I have some vertical and horizontal banding only with lowest brightness at the white background.
With maximum brightness no lines or whatever
AMOLED has a few imperfections here and there, so it's not surprising. But if it's bothering you too much exchange it for another one, it could have less prevalent issues.
Just performed a test using screen test app my screen looks great.

How high is brightness with test screen
Mine is fine too but 60 percent and more.But this one issue bother me pernament ( no matter if 30 or 70 percent brightnes)
Tuesday iam going for a new piece, hope that will not be affected worse than mine
Try viewing those shades of grey on your phones, it's usually the most problematic color. Use a low brightness setting (around 25%) at a dim environment.
This exists on all OLED screens. Its the exact same on my Nexus S. It has nothing to do with pentile matrix, but OLED.
Sent from my Galaxy Nexus using XDA App
Yes i had nexus one galaxy s galaxy s II so i can compare,nothing like that before that.
50-60 percent of brightnes
I have the Galaxy Note and it has the same panel as the Galaxy Nexus albeit at 1280x800 instead of the Nexus's 1280x720. (Super AMOLED HD with Pentile sub-pixel arrangement)
My screen is great. The whites are brighter than they were on the Nexus. The Nexus displayed whites with a yellowish tint especially on low brightness. Plus I can't seen any banding on the screen and I have tested it on White, Red, Blue, Green and Grey backgrounds.
Im getting a new Galaxy Nexus in a couple of days. Since this unit is from a later batch I hope that there is no banding on the screen too.
Funny, I have a similar issue to Delarock's on my Galaxy S2, manufacturing date is 19th of October. I'm still thinking whether to replace it or not since since it's only visible on dark'ish grey, I couldn't replicate it on lighter greys, white, or any other color at various brightness settings.

Hard for me to get a good photo but you can see the same problem on my NEXUS S screen. Its just a characteristic of OLED displays in general.

Really similar to the screen on my new Galaxy Nexus. I didnt notice the diagonal right away but that is certainly more significant. My screen a rosy hue in the bottom half and especially the lower left.
I'd love to see a similar picture of someone who says that their screen doesn't have it.
(Click for 100% crop)
So are some of these screens defective? Or is it really just the nature of the beast?
How does one tell what manufacturing date their device was made to? Would I be able to go to a store and exchange for a datecode that shows no banding issues?
I am having the same issue ... another thing I notice is weird issues with the camera while in a dark room. If I have my camera on in a low light room, I get this weird "dancing" of black blotches in the really dark areas of that room.
I like all solid black wall paper, I find the fastest easiest way to get it is to turn off the camera flash, put my finger over the lense and take a pic. Worked for every other phone I have but the GNex. I get a weird blotchy image ... now I am on GNex#3 (other 2 I returned for different issues) and I have noticed this camera thing on #1 and now #3. With the first one I assumed this was normal ... but after going from the second one to the third I see a HUGE difference in screens. With phone #2 I was able to do the phone/black wallpaper with no weird distortion. Now the really strange thing is that that same pic taken with the second phone (that displyed pure black on that device) shows up blotchy on device 3.
Hope this makes sense to someone lol cuz reading it back I sound crazy.
I just hope the folks at the Verizon store don't give me a hard time trying to get another one!
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.

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 !

Hey everyone,
I got my black AT&T Note 4 earlier today. I noticed the lower half of the screen is slightly darker, and has a slight pinkish tint on a white screen.
I do notice it in some apps, like Kindle when readinga book. Top of screen is slightly brighter, and when background is white there's a very slight pink tint.
Is that normal? Or should brightness be uniform and no tint?
EDIT: I added a photo. It's not a good photo but you can see how one side is tinted differently. In the photo the brighter top looks greenish but in real life it's not green. You can also the slight pinkish tint in the bottom half, which is the left side of the photo.
I wouldn't want to comment based on the image you uploaded directly since how a camera captures a digital display is much different than what the naked eye will see. If the picture on the panel is not consistent and appears polarized in any way, I would consider that to be faulty. Get it replaced.
Galaxy Note 4 (pink tint lower screen)
Hi there,
I have also noticed a pink tint on the lower half of the screen on new Samsung Galaxy Note 4.
As i intend to do a lot of drawing on this device the tint is unacceptable.
I wonder if there is a way to calibrate the display?
I had this issue with my Galaxy S3 display. I had at&t exchange it.
Have this same issue on my Note 4. Posted some pics over in the thread on this topic for the Note 3 before I thought to check here. Basically there's a brightness and gamma gradient from top to bottom. The top half is perfect and the bottom half gradually fades to a point where you lose the first 8-9 squares on the lagom.nl black level test.
This one emphasizes the black crush, which can be visible in video content on a dark screen (and makes dark colored backgrounds fade to black towards the bottom):
And here's one on a white background. At first it seems like a white point issue (which I would tolerate since it's common on IPS as well), but it's a brightness gradient:
Between this and the fact that AT&T disabled the slider for auto brightness I'm a little frustrated with this supposed best smartphone display ever (I realize this second issue isn't Samsung's fault, but the auto brightness is unusable without that feature). I bought the phone at Best Buy which is mostly out of stock right now so an exchange isn't likely, assuming they even take this seriously as an issue.
My note 4 does not display this issue.
No issues here. Display looks very consistent.

Have you tried a dark background in a dark room? For me it wasn't that obvious until I did this (was messing around in Sketchbook). If the majority of screens are better than mine I'll definitely be trying to get a replacement as this is bothering me.
I just installed Lux to resolve my backlight issue and its settings menu background fades nearly entirely to black at the bottom.
*Edit: So far it sounds like this is an anomaly. You would expect places like Anandtech to report on it if they'd seen that amount of variation. I'm going to have a good time trying to convince someone at BB that this is a real defect though.
Erica Griffin talks about this issue in her Note 4 review, around the 20 min mark: https://www.youtube.com/watch?v=-OyNWrQJzMY
I got a replacement and it's perfect. No pink tint.
So, if you have the tint return it. Not all Note 4s are like that.

Thanks, that was quite helpful. I think in general it's easier to trust reviews on retail-purchased devices over mainstream reviews with PR department selected units.
I went to BB today and looked at the display units. All perfect, but then that's not surprising (every company gives their display/review units a second QC pass, even Apple). I'll probably head to the only BB in the area that has units tomorrow and see if I can do an exchange. As long as they don't make me sign one of those "no more returns" agreements I've heard about I'm willing to take another shot in the display lottery.

Good to hear! I'll post my results after my exchange attempt tomorrow. Aside from the gradient I am impressed with the display. Not as bright as LCD in daylight, but I was drawing on a black BG last night and noticed that it has deeper blacks than my Pioneer plasma.

Fingers crossed for you to get a nice one like mine.
Yeah, the blacks and colors are amazing on the Note 4. The whites are not as bright as the iPhone 6+, but they are fine and way better than whites on my Note 2. In all other respects the Note 4 screen is overall better than even iPhone 6+'s excellent LCD.
One minor disappointment is the very high resolution has made some emulators dog slow as they attempt to render at full resolution, i.e. PPSSPP and ePSXe using ogle renderer. Hoping the devs find a workaround, maybe rendering at half or quarter rest instead - that would still be higher rest than my Note 2 at full rest. :laugh:
What's the color of your device? Anyone have this problem in the white version?
my note 4 has pink tint
I have the same problem on my Verizon white note 4 but on top half of display. Replacement should arrive by Friday :/
You can replicate this by looking at the screen at an extreme angle, obviously the ones that see green and purple straight on are screen defects.
I have a white version and whites are perfect and too bright at high setting. I keep mine half way. The whites are better IMHO than the iphones. The colors more vibrant and, the sharpness is ridiculously sharp. I dont see how they can improve it. I only thing there should be a waynto adjust the color saturation, because basic mode doesnt do much on mine.
My Note 4 has the same issue. It almost looks like the while balance differs from top to bottom, but it is really the brightness that is different.
This is a photo of my Note 4 showing a solid colored image at #030303 (very close to black). It shows how different the pixels in the bottom and in the top emit light.
Image can be seen at 1x.com/tmp/uniformity_note4.jpg

similar problem
I have a similar issue, though mine is brighter on the right side than it is on the left. Very noticeable with dark background in lower light situations as someone else mentioned.
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? )

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

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.
