Hi all,
Has anybody else noticed a yellowish tint to their screen, especially when displaying lighter colours, white, light blue etc?
This only seems to be the case when looking directly at the screen. If I look at it from any sort of angle the yellow tint is not there.
Any info or confirmation that others are experiencing this too would be much appreciated. If this is a hardware issue then I will return my phone.
Thanks all

Sorry to bump this, but I assume the lack of replies means I'm alone with this issue?
Should I get my unit replaced or is this a software issue?
Thanks
Mine is quite yellow too against my S2. Decided it must be faulty and it's going back.
Going to stick to my S2 with Cyanogen as it's much better...
When I go into my settings screen it has a yellowish tint in the bottom half of the screen where the top half is black.
When I go into my app drawer the background is black as it should be.

The gradient in the settings background is a feature.

I have not noticed any yellow screen in the settings menu myself.
I have been reading that the Galaxy SII had similar yellow tint problems when released and that it was corrected with a software fix?
I'm more worried that this isn't a hardware fault more than anything, software faults don't worry me too much as I'm happy to wait for a fix...comes with the territory when owning a smartphone
Think I will be returning my handset, the yellow tint combined with the volume problem is doing my head in!
I have been watching a few you tube clips and i don't see much yellowish tint on theirs but then again it does go completely black in the app drawer.
It really doesnt faze me as much as the volume issue though.
is it a problem or a feature?
I don't really know what to say, but let me give you my 2 cents.
First, AMOLED screens are all different for some reason, and I can vouch for this as I replaced my Nexus one 9 times for power button and various other issues, and each time the color temperature was different. Some were warmer (with a red tint) while others were cooler (blue tint). If you swap it, you might get a better tint, maybe even white if you're lucky.
Second, the Nexus S also had a tint problem (yellow tint) just like yours. The two display models at my BestBuy both are VERY YELLOW compared to my HTC Sensation and look really bad, but it might be because their screens were ruined from being on for so long. There was a post on XDA in the Nexus S forums who said he swapped until he got a "white tint" but then Google actually updated the Nexus S with different Color Settings and totally washed out his screen, while yellow tinted ones actually got better. If Google releases a color patch, you might not like it, but I don't think they will after the backlash from the Nexus S one.
tl;dr Get it swapped, it's a hardware issue. Swap until you get one you like, you paid for it, you deserve it.
Oh geez here go again, i thought the yellow tint was going to die with the galaxy s ii, guess not, it's alive again on the galaxy nexus , i swapped my galaxy s ii because the yellow tint was too distracting, in low "backlight" the white looked yellow , the one i got is less yellow but the colors dont pop as much as on the first galaxys ii i had

You're going to want LCD if you want perfection, but you'll give up great blacks and thinness+battery life, not to mention the phone entirely.
Keep swapping, took my 9 tries but it was worth it for my Nexus One

I've got the same 'issue'. While I understand it is a feature, it really looks odd/very greyish, especially on auto brightness.
BTW I'm starting to like that yellow tint. It really is helpful when browsing the Internet, because it's more pleasant for the eye.

The Galaxy Nexus screen looks so yellow compared to iPhone 4S display
It looks like he has auto-brightness enabled on the Galaxy Nexus.. it looks yellower unless you turn up the brightness.
The whites on the iPhone 4 are ridiculously clean and white, no phone compares to it. The blacks on the Nexus are also ridiculous and no phone (except other Super AMOLED phones) compare to it.
Take your pick, better whites, better blacks. The iPhone screen is still tops, but it's small. I have an iPhone 4 and a Nexus (just sold a GS2).
If I compare the screens side by side, then yeah, the utter blinding white of the iPhone 4 makes the Nexus white look kind of eggshell white, just not as bright or crisp. But using the Nexus on it's own and it's fine, white looks white enough when not being compared to the iPhone. The colors on the nexus are much more vivid and true to life than on the iPhone.
Nexus also has crisper text than on the iPhone 4 believe it or not. There is no perfect screen, all have +'s and -'s, you just have to pick which +'s you like best. For me it was the insane resolution, size and color accuracy of the Nexus. It's plenty bright, just not plenty white when compared to the ifruit.

definately noticed the yellow tinge... bloody Samsung!
actually the yellow issue on the GN appears to be because of the colour profiles that have been set in a similar way to how google updated the nexus S and altered the colors.
in AMOLED screens overtime the colours actually fade and become less vibrant now blue usually goes first and is at a much faster rate than the other colours.
considering that this fading occurs perhaps they deliberatly make the colours a bit 'warmer' to offset the blue fade time.
this was also interesting:
"Color balance issues
Additionally, as the OLED material used to produce blue light degrades significantly more rapidly than the materials that produce other colors, blue light output will decrease relative to the other colors of light. This variation in the differential color output will change the color balance of the display and is much more noticeable than a decrease in overall luminance.[63] This can be partially avoided by adjusting colour balance but this may require advanced control circuits and interaction with the user, which is unacceptable for some users. In order to delay the problem, manufacturers bias the colour balance towards blue so that the display initially has an artificially blue tint, leading to complaints of artificial-looking, over-saturated colors. More commonly, though, manufacturers optimize the size of the R, G and B subpixels to reduce the current density through the subpixel in order to equalize lifetime at full luminance. For example, a blue subpixel may be 100% larger than the green subpixel. The red subpixel may be 10% smaller than the green."
its quite possible that the tints that are experienced on oled devices are probably deliberate to offset the problems with oled technology.
someone here already mentioned that the GN screen isn't as black as the gs2 or nexus s. as in, a backlight is still visible on an all black background. can others confirm this? even better, can someone who owns both phones, or all 3, take a comparison pic? thanks

I have the Nexus and GSII side by side and there is no difference in the 'blackness' when the screens are switched off. AMOLED does not use a backlight; absolute black is represented by a switched off pixel.
One thing I have noticed is that in boot screen animation they use a grayish background rather than absolute black which is kind of stupid. Makes the screen look like a washed out LCD.
i should have been more clear. i was referring to the screen in a switched on position with lets say an all black wallpaper. i know how amoled screens use a switched off pixel for blacks but some people on these forums have claimed that they are noticing a slight backlight, especially visible in the dark

Galaxy nexus screen is pure black; however, it does seem to have more reflection when around light, and that light makes the pure blacks look not pure black.
But if you are in a dark area, blacks are pure black.

myself noticed this although I'm not really concerned for now ( I own a nexus s )
So are the pixels 'off' or not..that is the question!
On the Battery test thread the all Black and all White screens were comparable in battery life, which i wouldn't expect.

No, they are not off.
AMOLED screens have a minimum voltage applied when on. To turn a OLED pixel from fully off to fully on takes a lot more power. The contrast ratio of the sAMOLED screen is something like 100,000:1.

I guess the minimum voltage in GN has been increased at least compared to Nexus S. Here's comparison of my Nexus S (left) and GN (right). Pic is taken with 5 sec exposure. To be honest, the difference in that photo looks slightly bigger compared to what it is real life, probably because of that exposure time.
Black is from Dead Pixel Test apps black (second) screen. https://market.android.com/details?id=net.ujacha.deadpixel
aww that's kinda disappointing. I was really hoping for a pure black screen =/ you might be right about the minimum voltage increase being the cause of this
Well mine is BLACK and those pictures on my gn may look grey but the black around the phones show jet black (as viewed on my gn) Trust me blacks are black!
Disappointed, my Nexus S is really black.
Hope this is software issue and can be improved with future update.
you are correct the blackness is not pure black as my galaxy s, strange as it is using same screen technology
It is not pure black (as in a void of darkness) as it is like on my Nexus One. Very difficult to see... but seeable...

I've just done the same test using the same app (thanks for the link) and what I've noticed was the black wasn't pure black like Nexus S but software buttons were PURE BLACK. Because they are the part of the screen itself, it means Google changed it on purpose (or it's a bug)

Really hope this gets fixed
My screen is totally black when viewed when any light is around...like DAMN, black.
But I definitely agree when viewed in total blackness it looks like the screen has a (dim)backlight. Hopefully software and not hardware.
I think this could possible something that google have done on purpose to make the colours more "true to life" as with my S2 the blacks were gorgeous as the screen went off, but sometimes it didn't make the image very real as blacks were sometimes darker than they actually should of been
Any i don't know :/ - would be nice to have the option ie a switch on and off switch
Hallo friends, i read lot of about problem with this kind of display( pentile matrix)

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

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.

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!
Hi all. Few days ago, i've made a pure black image on my PC and set it as wallpaper on my Gnex. But when i view that photo in gallery (in full screen mod) i realize that screen is not 100% black, it's super strong gray but not black. I'm confuse that the screen is really Super AMOLED or a kind of LCD?
Its superamoled

Although its true that in theory there would be no backlight for an OLED screen, there is still a small amount of current that goes through just below the threshold of on/off for no lag when going from black to something else. Unfortunatly, the tjreshold will not be common for every led, so some leds will be lit. Thats what produces the small backlight even when displaying true black
Its super amoled (or amoled HD or whatever they call it) and is able to produce true black.
Xda dark theme shows no color difference between it and the nav buttons on the bottom.

There is no difference because the soft buttons are part of the display. Turn off the lights and you will see the entire 4.65" display glow a dark grey. It's a bit of a disappointment actually, I have a Samsung focus and galaxy S2 and the displays are BLACK. Side by side you can definitely see the difference, in the dark I cannot even find my Focus, the nexus on the other hand glows bright enough to notice.
You guys need to remember also that this is a PENTILE display, in order to get the 720P res, Samsung went with a pentile display. There is a big difference between the Super AMOLED displays on the other samsung devices and the nexus. The not really pure black blacks is one of the cons of the nexus' pentile display along with a slight yellow hue, viewing angle and a few others covered in many online articles.
Don't get me wrong, the display is still very beautifull in comparioson to most other phones. The resolution is amazing, I played a 4.2GB MKV of Avatar with MX player and it played flawlessly and the full screen (4.65") video was gigantic and absolutely crisp. But it's still not the AMOLED that Samsung customers are used to seeing.
so pentile or not if it displays black all led is turned off and thus dark no?
i understand pentile may affect other color reproduction but true black must be true black coz led is turned off right?
my previous phones were a gs2 and vibrant, blacks are blacks on all of them including this gnex

It's a PenTile Super AMOLED screen. This is as opposed to the Galaxy S II and Droid Charge which use Super AMOLED+ screens-- which use the traditional RGB stripe sub-pixel arrangement.
Looking at the button bar in the dark on my gnex, I can safely say mine is true black.
Sent from my Galaxy Nexus using xda premium
No. Like the guy before said, there need to be still a low current on the display so that there would be no lag when switching from black to other colors because it takes longer to switch on the display than changing the color.

For some reason these new HD amoled screens aren't showing total black like previous amoled screens. There are already threads we talked about theorizing why this is. Put next to the nexus one or galaxy s and its not as black. Perhaps its due to higher pixel density, or maybe a change in the technology. But you're not alone, just have to live with it.

It's more of saving battery. When it's pure dark, the individual OLED's are almost completely turned off. I say almost because some current still runs through it but nothing like what an LCD would.
And it's better for contrast?

Higher resolution will most likely result in more possible backlight from true black. (Because of the greater amount of leds being over the threshold)
And i cant says my screen is totally absent of any light, but it is damn friggen close.
Any AMOLED screen will beat the crap out of LCDs. The contrast is an order of magnitude higher thanks to the screen generating its own light, thus being able to shut down fully (or almost fully) to provide no light.
Why do you complain that there is a minuscule amount of current going through the current with a barely noticeable in pitch black amount of light being emitted, when any other screen will be VERY noticeable at night when displaying black?! This phone's screen is amazing. Yes, it's not perfect, but it's better than most (all?) other phones' screens out there. You know, screw that, this thing is probably SEVERAL THOUSAND TIMES BETTER THAN THE MONITOR YOU ARE CURRENTLY STARING AT.
I was under the impression that oled screens were capable of extremely deep blacks, to the point of there being no light produced at all. I just got my Play nexus, and I'm not seeing that at all.
Black on this screen is bright, just as bright as the LCD on my old G2x. Is this normal or is my device defective?
Sent from my Galaxy Nexus using XDA
Not normal. Make sure the color you're looking at is actually completely black, and not black-adjacent.
We've already discussed this. For some reason the new amoled screens don't display black like previous amoled screens from Samsung. We don't know why, maybe the HD. My nexus one is way darker side by side. Oh well.
