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.

Got mine today. The yellow tint was the first thing I noticed. I know it's fixable, but it's annoying.

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.
I am using Lightflow to control my new GSM Galaxy Nexus notification light. However, unless it is flashing a primary color, like blue or red, the light color is slightly off. For example, yellow comes off looking reddish green while white looks like a purplish green. Even with darker colors, it doesn't look solid. Is it just my phone or has anyone seen an issue like this? Is my notification LED defective?
Thanks

No; at least not from what you are describing.
Yours is fine, It's just a poor RGB LED setup.
Anything that I can do about it or do I just live with it?
Have the same problem. Is this normal?

Same issue here as well. Unfortunately, it seems fairly normal.
I haven't seen any real "fixes" yet and I'm sure if there is one. If there is one, I'm sure somebody will post up and help us out.
Only idea which comes to mind would be to poke around in the sysfs area to see if the stock kernel provides any controls of the LED and what those controls are ...
Is this a sw or hw defect? All galaxy nexus have this problem?
You'll just have to live with it, as do we all...
I have this too. It also looks like it's obstructed in a one way or another.
Isnt't yellow a primary color ;-)

There are 3 leds RBG (red blue green) that perform additive color mixing. And since there are only 3 leds (one of each color) it will seem separated when mixing of multiple colors occurs. In the past on other devices the color changing leds were surface mounted on the pc board with a plastic piece that would reduce the spread/mixing and diffuse it to a small 1/32" visible area on outside of the device. With galnex's thinner design with less diffusing and add in making the visible notification area 3/32" will make seeing a small portion of the individual colors when mixing occurs.
And yellow is a primary when dealing with subtractive color mixing (i.e. cyan magenta yellow black) also known as "cmyk" which is used for full color printing.
good day.
I've never seen so many ocd threads for any one particular device on a software development site ever before.
Chopper, I was about to explain it but you did the perfect job, nice one.
(I have repeated fights with my wife over what the primary colours are. She thinks in terms of art, I think in terms of light. But as our eyes see light, I'm right )
My colors look fine, with lightflow

I am positive that I am being paranoid about this but I thought I'd ask you guys anyway - when you guys use light flow to control the LED - if its a mixed color like, white, orange, cyan - do you see residue of indiviual led colors around the notification light? I mean when I do white I see a tint of green in one corner of the notification area, a bit of yellow, a bit of red but from a distance it looks white. I know white is a mix of all those colors but I just wanted to confirm that the LEDs on my phone arent out of place.
The notification LED isn't uniform; that's normal. It's good enough, you shouldn't bothered by it, as long as you can tell red from orange and the likes.
Thanks for the response!
Rgb led.

i see the mixed colors as well for the color white. my nexus one LED did not do this, but i figure it's normal since samsung used RGB to make up the LED. they just must have positioned them differently in such a way that there is slight bleed thru. no big deal to me.

Our Nexus Ones had a large translucent trackball to further mix the colors....
Yep, whatever diffuser they put over the top of the rgb led doesn't mix colors very well at all. I almost miss the Nexus One track ball.
Could be worse, the Nexus S doesn't even have a notification LED.
it will get bad when we're *****ing about phones that didn't holographically project who sent you a text or email. but then again who wants to see your grandma naked?
The other day I noticed that my once stock white colored notification LED was acting strangely. It now is multicolored and seems to have a slight flicker when it goes off. I went through Samsung US support steps, removed apps, then full factory reset. Still same problem. I installed Light Flow and tested all colors. Most work but still with a bit of a flicker. White is not working. It displays in three colors, yellow pink and green/blue? I suppose my LED has broken. Has this happened to anyone else? Is there a solution? Samsung US will not support the repair as it is an international GSM phone.
Thank you.

Yeah white isn't really white, its a combination of three colors. Its normal.. no biggie
Well mine is also like that..
Sent from my Galaxy Nexus
I have had my phone since January and it was always a white notification. My old Nexus One was also always a plain white notification. I am pretty sure thats what stock Android intends it to be. The multicolored just started. Either way Light Flow when set to White should display a white notification but it cannot. I am almost certain my LED is defective. Anyone else?

As proved by Newton:
White light is the effect of combining the visible colors of light in suitable proportions (the same present in solar light).

Ok, so... no help here. Thanks anyway, guys.
I sure wish my LED could be fixed. <head down>
Everything you describe is normal.
You probably just never noticed it before.
I actually did notice it and that is why I have posted here. The notification light is supposed to be white. Not multicolored. I know this phone like the back of my hand. The led has changed.
Mine has been like exactly what you've described on both Nexus' that I've owned.

It's a tri-colored LED (red, green, blue).
It displays different colors by mixing those 3 primary colors.
To get white, it mixes all 3.
The 3 LED's aren't close enough together, so around the edges you'll see the individual colors, but in the center it will appear white.
At certain distances/angles/lighting conditions, it can appear almost fully white.

If you insist that it was pure white before, then somehow you had a white LED and it has transformed into a RGB LED.
I'm pretty sure no Galaxy Nexus's were shipped with a white LED, and certainly not ones that can transform.
AFAIK
The notification LED at the bottom of the phone has always been a 3 color LED. Red, green and blue. To get white it turns on all 3. Other colors are variations on a theme.
Thank you, terryhau.
My notification light does not look like it does in that video. It is now mostly pink with a green hue no the bottom portion and a purple/blue color in the top left hand portion. It DID NOT used to be like this.
I guess I need to post a pic somehow.
Maybe something like an update or .apk has changed the behavior of the LEDs like reduced the output which would explain why you now see all 3 colors instead of white.

I did a full factory reset hoping that may be the case. No luck. This hasn't happened to anyone else?

The video shows that it is not pure white, but a mixture of colors. Kind of hard to see because of the bad camera.

Yes. And in the video it shows what my led looked like about three days ago. It no longer displays that way. Now the three colors are glaringly obvious with a bit of a flicker as it fades out.
I am having the same issue. I have a galaxy nexus from sprint and the play store. the sprint one is perfect. all colors requiring a mix of colors show perfectly like pink, magenta, lime etc. However the play one does not. its almost like its off center so with lime you will see a bit of green and then orange on one side. Pink is slightly pink on one section then almost white every where else. Purple is purple and then has a nice section of blue on one edge.
So my question is those who have replaced your screen is the led attached to it or is it part of the speaker daughter board?
My led is darned close to white (accepting Newton's physical laws etc.). I'm thinking that if yours has changed then perhaps it's damaged, but perhaps your rom settings have (been) changed and your notification colour is now set differently (by default). What rom are you using?
I'm using CM9, which nominally allows me to have notifications in different colours for different apps. I find when I pick colours from the chooser, though I'm meant to have complete control over the colour, in reality I can get white, red, blue, green, and different rotations of rainbows.
Clarification: when I say I can get 'red, blue, and green', I mean properly: I get a solid circle of whichever one of those colours I'm aiming for. But anything else (e.g. yellow, orange, cyan, magenta, lilac, etc.) will be a the chosen colour in a small part of the circle, and an array of all the other colours elsewhere in the rest of the circle.
i can get all those colors too... but only on a portion of the window. white will show green, blue and pink on the side.. but not just around the edges. I think this is what the OP was talking about. I honestly do not think its a software issue as i am running lightflow on both of my nexus's and one is has run cm9 and AOKP witht he same results. It has to be a hardware issue. So if any one can answer this, is the LED attached to the screen or the lower speaker daughter board?
The o5 had such a doll notification light. Has this improved?
Unfortunately, I can't compare it but it is definitely very low in terms of brightness. I used to know the Nexus 5, Nexus 6, Nexus 6P and OnePlus One and the OnePlus 5T has the lowest LED brightness I have seen. It isn't s big issue though but sometimes a brighter notification LED would help outdoors.

I can only compare it to the 3T and it is lower in terms of brightness on the 5T. Still perfect for me to see it in any light condition.
I was so grateful that it was so dim, last phone was Galaxy s7 and dam it lit the room up at night
i don't have op5, but i have op3t, all i can say is 5t's led is much darker than 3t's. So sometime if your view angle is too big , the led blink notification is hard to notice.
It's about as bright as the Pixel XL. Not super bright but acceptable.
Best to fix with Always on Display.
No, it's the same. Really annoying since there was a ton of complains about that on the OP5. I have had both.
