i've had my nexus for just under a week and i've noticed the black lines as well. if i lower the brightness of the screen the black lines are more visiable and especially against lighter backgrounds. i've only found one article on the web that has highlighted this problem too, but would be interested to see if anyone else is having the same problem :confused:
[Samsung Galaxy Nexus] farfromovin:
No screen issues here!
[Samsung Galaxy Nexus] assisterah:
That's exactly the same problem I have , I even have those thing with the same shape and location as yours.

Can somebody explaine this?

Come to think about it I believe it is a screen quality issue in a certain batch.

I noticed the problem when at night with all the ambient lights off. You will see it better when using a light grey or black background. Everybody please check your phone.
[Samsung Galaxy Nexus] Yaminashi:
Damn, seems like the same problems that plague the SGS2. I wonder if its just the way the new SAMOLED Screens are manufactured?
[Samsung Galaxy Nexus] famoustito:
I just opened mine and i have the same problem! the question is have samsung replaced the unit or does the reseller?
[Samsung Galaxy Nexus] kristovaher:
This is how AMOLED screens work. They are splotchy when in low brightness and black background. They are also grainy in low brightness. This happens with all AMOLED screens, it simply is harder to notice, pictures posted here have been edited in post to highlight the issue. Raise brightness a little and the problem is gone.

It is not a faulty screen.
[Samsung Galaxy Nexus] elsif1:
No issue that I can see here, fwiw. Looked using low brightness on a black bg
[Samsung Galaxy Nexus] rikbrown:
Mine had graininess and banding. When compared to my friend's, although there was still light graininess on lowest brightness, there was not any obvious banding.

So I took it back to the 3 shop (13 days after purchase), luckily asked a staff member whose personal phone was a GN. She compared hers, same lack of problem, so just swapped mine for a brand new one then and there. This one is much better - a bit of graininess but no banding.

Now my phone is perfect :)
[Samsung Galaxy Nexus] sblantipodi:
what's this?

https://picasaweb.google.com/105010...id=1OIgW7-M4cmivJdnzBLDlw#5679627936172713522

isn't this a defective screen?
[Samsung Galaxy Nexus] kristovaher:
No.

That is how these screens work. There are these spots on very lowest of brightness setting and with full black color. Every screen has it, most people just never notice it and even if you go and do the magic required for you to see it, it is kind-of stupid to begin with.

If you get a replacement you will have it again. Maybe a little less, maybe a little more. That's AMOLED.
[Samsung Galaxy Nexus] sblantipodi:
Ok but when you see this?

Lowest brightness on full black color?
[Samsung Galaxy Nexus] kristovaher:
You have to be in a very dark room and have your eyes adjusted to the darkness. Then the phone needs to be in lowest brightness setting and screen has to be completely black (you should cover the on-screen buttons with a hand). Any sort of light will easily make your eyes adjust too much and you'd not notice.

And then you should see very faint black spots on the screen. It is nowhere near as visible as the photo shown by other posters here because the photo has been edited or taken with a camera that adjusts the brightness.

It is not an issue and there's no 'fix'. AMOLED screens use organic light emitting diodes and have a feature of being 'off' when color is black and fully on when color is white. Now, all of those diodes are not 'equal', this is why you can also spot things like slight noise when looking at gray or white backgrounds with lower brightness settings.

This also means that some of those diodes act strangely, because they are not 'equal'. This causes that noise, those lines as well as those spots.

When it comes to those spots, they won't 'change' much over time, if at all. All of my AMOLED screens have had it one way or another.

This is also related somewhat to how AMOLED diodes change over time when it comes to brightness. They have more 'memory' and each diode never represents 100% accurate color (but all together they get very close). These diodes don't get dead pixels, but they can get pixels that get out of line and start showing brighter or darker colors after a while than they should. This is why after few years you may notice on solid backgrounds that some areas look similar to LCD burn-in's (notably the clock widgets, top notification bar and so on).

You can also notice this when you switch to solid background in certain colors, your previous image may still be fainly visible for a short time (especially the notification bar).

But all of those anomalies with AMOLED screens are limitations of the tech today. It is a trade off to get better blacks and contrast on the device. In the future these anomalies will vanish, but for now we have to live with it.

In short, your screen is just fine, the black spots, noisyness, lines in low light and so on are not a sign of a faulty screen. It is a sign of AMOLED screen that is just quirky due to being a little organic.
[Samsung Galaxy Nexus] ferris2375:
err...not all AMOLED screens have those ugly spots. Faint lines and some noise are one thing, those blotches are terrible.
[Samsung Galaxy Nexus] Yaminashi:
Not to sound like a jerk, but do you manufacture AMOLED screens? I mean is this information directly from Samsung? I'd like to know what your sources are, as I'm sure it would put thousands of minds at ease and save people the trouble of returning phone after phone only to end up back at square one
[Samsung Galaxy Nexus] elite_is3:
mine is similar to this, i have a green band in the top area, but on top of that i noticed yours seems to have a brighter green hue in the top half of your screen. Mine is exactly the same in this regard. Weird...

i contacted handtec about mine, but im unsure if i should get a new one.
[Samsung Galaxy Nexus] alias3800:
Just to throw in my own tiny dilemma: My handset (which I purchased second-hand out and shouldn't have) has a few dead pixels off to the top left corner. It's really small and only noticeable when looking at either a white screen or a gray screen. I mean, it's decidedly tiny (about a few pixels down) and there's not much I can do now other than keep it or sell it on. I think I may keep it in this case and just avoid other (aforementioned) issues.

I'm just hoping it doesn't bother me several months down the road, because I'm actually planning on holding on to this phone for a while

[Samsung Galaxy Nexus] oatterzonxda:
yea that screen looks pretty bad. This problem is well documented from SGS2 and its variants, especially US variants with the 4.5" screen. it seems that AT&T GS2 has less cases but dont quote me on that. I manage a retail AT&T location and i have a group of hardware nerds that come to me a lot about these things. Skyrockets have more of the issue like this. my captivate and infuse is flawless, however my skyrocket is ****ty just like that picture except i had less splotches. You were a bit unlucky to get such a ****ty screen i think. my gnex does not have splotches but i have a lot of noise/debris and 2 horizontal lines. unfortunately thats how AMOLED is i believe.
[Samsung Galaxy Nexus] dinan:
As mentioned before... all SAMOLED screens have this. It's not noticeable to the naked eye usually and it takes a long exposure camera to pick it up. My Galaxy S2 has it, my Nexus S has it, etc. If you can see them easily then that's an issue but it shouldn't be easily seen even in a dark room.

[Samsung Galaxy Nexus] FC1032:
Hey guys!

I also have a GN, the prob for me seems most evident in auto/low brightness from the phone. However, once at 30%+ the problem disappears.

I too think its an AMOLED thing mostly. Hear me out: I have the AMOLED Nexus one, which had a fair few things wrong with its screen, there were ghosting lines next to text, pentile was visible etc...

I just tried the same images on the N1 and GN, the problem is more evident on the GN, but its also there on the N1. I think I probably didn't notice the blotchy-ness on the N1 because its not as high res. However, the GN has alot more pixels and when the screen is that much larger, its much easier to spot.

Basically, I don't think it's too much of a problem, if the auto brightness didn't make the screen TOO DARK, this would barely be visible. Like I said, having the screen at 30% + solves the prob for me.
[Samsung Galaxy Nexus] NatTheCat:
It just depends on how you feel about it i suppose. If you cant live with it i suggest taking it back as i did. I know i feel better now.

kristovaher - Some great info there which i know we all appreciate. I just think sammy should sort out the low brightness issue so we dont all return our phones due to not knowing its suppose to be like that. Anyway good luck with your issues...
[Samsung Galaxy Nexus] ribooo:
Anobody else having problems with the colors of the screen?

Here a screenshot of my nexus:

The keyboard on the left side has other colors than the right side. I think its NOT normal?
[Samsung Galaxy Nexus] jpalo:
I've now stared the buttons few mins and maybe there is slight color difference between L and Q, but not as obvious as yours.
[Samsung Galaxy Nexus] ChongoDroid:
Mine is actually really good as far as blotches but really the purple at low light kinda grew on me. 15% is my new 0% and 0% is my new ereader mode lol.

The only thing I'm not happy about is the tiny pop after ANY UI sound. Don't believe me? Enable lock sounds and lock your phone... then listen with your ear to the speaker. Key press.. touch sounds.. and lock sounds...
[Samsung Galaxy Nexus] FC1032:
I also have the colour issue. Its slightly green towards the top if the screen and pink on the bottom. Not too obvious, but once you notice it it's hard to ignore.
[Samsung Galaxy Nexus] TheLuckys:
My Galaxy Nexus displays both problems too, the slight color difference between the top and bottom of the screen and the splotches. Only on my GN the splotches show up on a black screen on ANY brightness level.

I don't really mind though, as you don't see it if you aren't looking for it.

A thought about the color difference: maybe this is caused by the curved display? I think the screen itself isn't curved, but the glass is. This means the distance between the glass and the screen isn't constant.
[Samsung Galaxy Nexus] Nutsonfire:
I have only one black spot and you have to look for it. But I have a reddish zone top half right of the screen and worse I have like a grid on the whole top half of the screen in low/medium brightness setting and certain shades of white. There is like a stripe and then everything above looks like a grid. But on tapatalk's white background for example it doesn't do it.

Anyone else have this?

To be honest my Nexus S amoled screen is a lot better, I never saw any defects on it. On the Galaxy nexus these defects jump out immediately unlike the black spot you have to look for.
[Samsung Galaxy Nexus] Crazy CS:
yeh mines not as bad as that..... you can see if you stare at it for a while though.
[Samsung Galaxy Nexus] sblantipodi:
My screen is ok but I have a speck of dust under the screen, build quality

is sufficient and this is really something disappointing.
[Samsung Galaxy Nexus] jake21:
I didn't want to quote the picture; but I think it is simply uneven back-light. These pentile displays have a bit of colour when the backlight is low (the razr is green and I guess the nexus is more purple). Anyways that's my guess as to what you are seeing. To be honest it doesn't look that bad....
[Samsung Galaxy Nexus] FC1032:
¯\(=^=)/¯ Judging from the responses here, it would be likely that even getting a replacement will have the same issue. Might as well hold onto it.

Mine has both the problems: grid like overlay at low brightness and green/pink tinge on the screen. Both aren't bad enough to be a deal breaker, but overall the screen is still very good.

Maybe there will be a render effect option later on like the Nexus one (the horizontal line ghosting problem) that will fix this.
[Samsung Galaxy Nexus] Rusty!:
AMOLED screens do not have a backlight.
[Samsung Galaxy Nexus] oohyeah:
I noticed the same issue:

- UPPER HALF of screen looks brighter, or more of a greenish hue

- LOWER HALF of screen is dimmer, more of a reddish hue

(In portrait orientation, that is).

For example, open up the Google homepage where it's mainly white, and look at the difference in hue between the top half and bottom half.

DOES ANYONE ***NOT*** SEE ANY DIFFERENCE?

I was thinking of changing it to a G Note, but does that have the same problem too??
[Samsung Galaxy Nexus] crazeco:
My new Verizon Nexus has a similar red/green issue (red on the left and green on the right). It's very light but noticeable when reading (from left to right). Bumping brightness helps.

Do you see it when you load up pixel tester? Oddly, I don't see it in that program, the screen when displaying white or gray looks fairly uniform. It's just mainly on web forums and in g-mail.

I think I'm going to keep it, my banding issues are not significant and I'd hate to get a phone that's worse.
[Samsung Galaxy Nexus] crazeco:
Scratch that. I got tired of seeing the color shift. I took the device back to Verizon and got an exchange. New screen has a slightly more quilted effect, but no real banding to see and no color shift that I notice. So far I'm glad I exchanged.
[Samsung Galaxy Nexus] beepbloop:
My GSM Nexus does strange things at lower brightness.

1. At low brightness, it appears the top half of the screen is brighter than the lower half. It depends on what is being displayed on the screen. On the homescreen it appears normal but when you open the app drawer it's very noticeable.

2. When I drag the notification shade down the bottom half of the screen again darkens.

3. Overall, the gamma seems to be set too high on the phone, especially when viewing videos.

I hope someone can figure out how to tweak this screen!
[Samsung Galaxy Nexus] columbo:
I bought my Galaxy Nexus from Three UK over the phone on the day they released it. The screen had a slight yellow tint, and it had faint lines running vertically down the screen, which were especially visible at lower brightness levels.

I took my phone into a local Three store and compared it to another Galaxy Nexus owned by a member of staff which did not have the same issue. We compared using the same apps at the same brightness. His screen was much clearer and less yellow looking. This proved to me that my phone's screen was faulty, so I ordered a replacement. Because I bought the Galaxy Nexus over the phone, I couldn't get the phone replaced in store, so I had one delivered to my home a couple of days later.

My replacement is better. No lines or yellow tint. However, there is now a dark smudge on the right hand side of the screen which was there when I first turned it on and won't go away. As with the vertical lines on my first handset, it's not so bad at the brightest level, but on lower and medium levels it is really distracting.

I'm now awaiting a second replacement handset which should arrive on Tuesday. I am wondering whether Samsung has a problem with quality control, because this sort of thing seems fairly common, judging by the threads in this forum.

Perhaps there should be a sticky thread collating all the screen problems. It is clear to me now that this is not a problem affecting every handset, but because there are quite a few people with similar experience it could become embarrassing for Google and Samsung unless they do something about it.
[Samsung Galaxy Nexus] ]grimm[:
I second columbo on my experience. I've also seen both the dark patch on the right side of the screen and a yellowish-green tinged display and am waiting on my third unit.
[Samsung Galaxy Nexus] AMaench:
I think I'm experiencing the same problem. At low light dark environments you can see the pixel lines it's extremely annoying. On white backgrounds like webages the lines are clearly visible. I don't know if this is standard with pentile screens I know the moto bionic did not suffer from this but the GN screen is far from as good as the Droid Charge is.

I don't know if I should get another one or just live with it due to the type of screen that it is?
[Samsung Galaxy Nexus] magicriggs:
Are these the lines you are talking about?
[Samsung Galaxy Nexus] mcgon1979:
Im on my 7th replacement due to screen issues.

Ok Im not. But I'm amazed at those who are. When someone finds the flawless phone, no dead pixel, no banding, no colour tinting, no variations of light and dark, no blotches etc... Call me. please.

:eek:
[Samsung Galaxy Nexus] AMaench:
This is what I am getting the dark lines between where the pixels sit-

On a white background I can see the dark lines where the pixels line up like in the test above.

is that normal for a pentile screen ? From what I read it is but I wondered if others were seeing the same thing?
[Samsung Galaxy Nexus] AMaench:
until you said something i did not notice but you are right there is a very small thin white line on the far left edge of the camera when it is on.

I take it that is considered a defect?
[Samsung Galaxy Nexus] RickROM:
My screen has faint lines also. Going to go compare it to one in the store tomorrow. My Nexus S did not look like this.
[Samsung Galaxy Nexus] :
It looks like they are supposed to be there seeing as that picture is a screenshot...
[Samsung Galaxy Nexus] FC1032:
After a month of getting sent around, I got mine back. Looks exactly like my previous one: pink and green tinge on opposite corners and grainy at low light.

I'm starting to wonder if its been replaced /fixed at all. I'm giving up, nor worth the time and effort to do all of it again only to receive it and find the same faults
[Samsung Galaxy Nexus] kwiggington:
So the only way to see this is stand in a dark room and turn the brightness down all the way? Doesnt sound like it would bother me much unless im hiding in the bushes after midnight

I had the same problem with my 1st unit. I think it's a faulty camera sensor. Had a line right down the middle of my screen the left side was okay but the right side had discoloration and horrible pixelation. I showed the people at Verizon and they exchanged it no problem

I'm very disappointed
[Samsung Galaxy Nexus] dk_iceman:
Jesus all these problems you all talking about, I've seen an all my AMOLED devices, SGS2 (on all 10 devices i had), Nokia N8, Nokia N9, Nokia Lumia 800 and Omnia W.. they all had some sort of problem that your are talking about in this tread..

My SGN has the spots in camera on VERY low backlight, why care about it when it doesn't affect pictures and can not be seen in normal light use ??

my screen has a warm tint, on white, but for the first time EVER my screen is pretty darn even when it comes to uneven color like the yellow tint on SGS2.. here is my GN PERFEKT...

when I'm in the settings menu where you have the grey fading from dark to light i can see slight color banding i think, but still much more perfect than any other AMOLED screen i have ever seen...

I think that AMOLED does perform best when it comes to black level... but damn LCD or any other screen doesn't have so many faults
[Samsung Galaxy Nexus] rye&ginger:
Agreed, this is the nature of AMOLED currently when at low brightness.

use an app like ScreenFilter and you can see how it gets even more off colour when you lower brightness past stock levels.

https://market.android.com/details?id=com.haxor&hl=en

Gnex just happens to have a low setting which is perhaps too low and you see this effect. Galaxy S did not do this to me unless I used the app I mention above.
[Samsung Galaxy Nexus] SL1VR:
I have this line as well.
[Samsung Galaxy Nexus] ciscostud:
I love how colorful the screen is. It's no fun keeping it dim all the time.
[Samsung Galaxy Nexus] sam2c:
I have these two darker spots on the screen, 1/3 of the way up from the bottom in the center (imagine if the nexus has nostrils). It can be seen on whites at low brightness (less than 15) and on greys at most brightness levels, but it gets less noticeable as u go higher. Is this a consequence of the samoled? Anyone else have these darker spots?
[Samsung Galaxy Nexus] FC1032:
I've noticed black spots when I view black backgrounds in a dark room, however, its completely unnoticeable in normal use.

I do get a slightly darker line vertically down. Also noticeable at low light.
[Samsung Galaxy Nexus] KLUVJ:
i too have like around a hundred blackdots spreaded out everywhere
[Samsung Galaxy Nexus] techno_techie:
I have a photo of the speckles I have. There are a ton on my display. I have to wonder if it is normal or not. It is driving me nuts, though.
[Samsung Galaxy Nexus] sam2c:
I have the bands too, but these are like two pea sized spots that look darker than the rest, even the bands. Since it really just noticeable on grey, im assuming its an SAMOLED thing, but im not sure
[Samsung Galaxy Nexus] arirang:
lol! Can't believe that had to be pointed out. I wonder if iPhone forums are like this.
[Samsung Galaxy Nexus] sam2c:
Sorry double post
[Samsung Galaxy Nexus] FC1032:
Hmmm, sure hope it gets better for you.

Funnily enough, my screen had a horrible green and red tinge/tint on opposite corners. It was even visible at highest brightness, over time however, the tinting seems to have faded and now the screen seems to look much better when I just got it.

Who knows, maybe these new amoleds need running in? My previous nexus one was perfectly fine out of box till now...
[Samsung Galaxy Nexus] droidsrus:
These screen issues you guys are talking about appear on all amoled screens. Some are worst than others. I never notice it unless I really try to look for it. And I never noticed it before until someone on xda brought it to light. Its noticible mostly when the brightness is very low and on greys. It bothered me at first but with normal use I never use the phone on its lowest brightness levels and I barely go to sites that use greys. So therefore. Not a bother to me.
[Samsung Galaxy Nexus] techno_techie:
I've attached a photo. Let me know if this is what you are seeing if you have this screen issue. The photo is long exposure; to the naked eye, the screen is a very deep gray/black.

And I didn't have to do anything special to see it in the first place. I was watching Netflix with no light on in the room. I wasn't looking for them, but they do bother me.
[Samsung Galaxy Nexus] minhqp107:
I had the same problem with my gnex, then I sold it, got another one and this one does not have that defect.
[Samsung Galaxy Nexus] techno_techie:
I just called Asurion. They are sending a new unit. I've done research the past 3 days - there are folks without the anomalies. I'm bound and determined to be one of them. (for $300, I'm going to figure it out!)
