OP, your phone is defective. Return it for a new one. Seriously, the issues you describe are NOT common on these phones.
[Samsung Galaxy Nexus] EarlZ:
So why is it not visible on my Galaxy S1, Samsung wave and Galaxy S2?

Not also visible on 2 of my friend's Galaxy Note.
[Samsung Galaxy Nexus] Spronx_:
got my hspa+ version from the UK, honestly don't know what you r talking about with these 'lines'. My screen is perfect nd sharp and vibrant. It does suck battery but that's to be expected. Root + under volt offsets this and I get 26 hours+ normal use on a standard battery.
[Samsung Galaxy Nexus] EarlZ:
Your phone is not affected hence you remain ignorant on the issue, luck.
[Samsung Galaxy Nexus] eus107709:
I don't know why some people are so hostile. So its not a perfect phone for everyone, who cares?

I just asked the three people next to me if they can see these imperfections. Two say they can't while the other and myself can, its clearly visible to us. But to be really bothered by it, you have to be damn close to the screen..which isn't a good idea anyway. Otherwise it isn't a deal breaker for 99% of the world. The super saturated colors are annoying to me, but it might be worth it just to hear people commenting on how gorgeous the screen looks.
[Samsung Galaxy Nexus] EarlZ:
The hostile ones are always those who dont have issues or fail to see it. Thats always the result. On my screen even at arms length its visible at 100% brightness even on whites. But ill have this one replaced till I get one that meets my needs.
[Samsung Galaxy Nexus] jkc120:
Is anyone else seeing the blockiness described in this Galaxy Note thread?

http://xdaforums.com/showthread.php?t=1344714

I'm seeing what is described there on my Nexus. A good example is this video:

http://dl.dropbox.com/u/28717002/drwho.mkv

In the first few seconds of the video, you can see the "halo" effect above the earth and there are (at least on my phone) three distinct "not quite black" colors in a concentric pattern. The blacks around the outer part look terrific, nice and deep. It seems to be some sort of dithering or color space mapping thing or just that the true black areas are not lit up at all and this gradient or blocky effect is a result. Hard to describe, but if you watch that video on your Nexus, you can't miss it (unless of course this phone and my previous one it replaced both have a screen issue).
[Samsung Galaxy Nexus] ianwood:
I have to say I am disappointed in the banding that shows up under certain conditions. Grey backgrounds in low light have 3 or 4 chunky vertical highlights. Maybe my screen is defective but 90% of the time I can't see it. I am reluctant to go through the headache of returning it especially if I am likely to get a replacement with the same issue or worse.
[Samsung Galaxy Nexus] AMaench:
I have gone through 3 LTE GN phones. Two had really bad vertical lines and a yellow tint to the screens. This last one is perfect other than the small white line when you go into the camera.

I had the same issues with my nexus s and the screen either separating from the molding below it or having color issues. I honestly think Samsung just has horrid quality control and just doesn't care because I have had a bunc of Samsung phones but the are not near as good as HTC when it comes build quality. The nexus one was and is a beast, mine still works and looks great. I wish Samsung would better patrol their equipment.
[Samsung Galaxy Nexus] EarlZ:
They make great phones but the quality control is really low, I cant fully blame then since others are accepting obvious defects as 'normal' or 'part of the technology' if only there was another competing brand that offers great phones.. (sigh)
[Samsung Galaxy Nexus] Galitrin:
I am also experiencing vertical lines on my GN, only in grey/white backgrounds with low brightness level... or when opening Android Market at any brightness level.

It seems it's a generalized problem, but it looks like some lucky people dont have this problem so... Should i get a replacement? The newer one could be even worse...

Best regards,
[Samsung Galaxy Nexus] EarlZ:
If the store allows checking/choosing then do so.
[Samsung Galaxy Nexus] kms108:
I'm on my fourth gnex as a return, and been through 5 units in the shop, lucky i know the shop manager so i dont get the funny looks from the shop assistant, anyway

first unit--1 bright pixel problem

second unit--hanging and screen jumping around

third unit --scratched on top of screen

fourth unit--looks perfect upto now

the other 5 units were rejected by me in the store during checking, they had bright pixels problem, scratched screen on outside, scratched screen inside glass(not the LED lens) and some screen problem that didn't convinced me to take on.

of all the units, the screens looks good to me, there are lines, but thats in all amoled screen, it's just either stands out more or very faint, but i can put up with it, and so far the unit i have now, i'm quite happy with it.

and with the pixels problems and screen problems i am very fussy, evern the manager said that to me, as you know it's very hard to check in the store due to bright light, so i had to cover myself and the phone with my coat, and i had everyone looking at me.

if you need to check for dead/bright pixels and screen problems use this app, it's better than the one list at the begining of this thread, use the white, light grey and dark grey too see much clearer but do go through all the colours, and in a dark room.

http://www.appbrain.com/app/dead-pixel-tester/net.lostlinksearch.android.deadpixeltester
[Samsung Galaxy Nexus] EarlZ:
At least you got a good one after 5 exchanges!

And no the lines maybe normal but its unacceptable to me and some because other units dont have it.
[Samsung Galaxy Nexus] droidstyle:
I'll be happy to take it off your hands!
[Samsung Galaxy Nexus] Crazy CS:
I'm not even going to bother changing mine. I'll wait a few months and just buy an OEM screen and replace it myself. Give them sometime to make more panels....
[Samsung Galaxy Nexus] tcpsyn:
I agree, completely.
[Samsung Galaxy Nexus] kms108:
the screens aren't cheap, and if unlucky you may end up with a even worst one.

either accept what you have, at least there is no scratch or pixels problem, or just get a non super amoled phone.

you eyes will probably adjust to the screen, most of the samsung phones i've used has a amoled type screen, and these problem are normal, but i got used to it, as long as the screen is not scratched or contains dead/bright pixels, i'm ok with that.
[Samsung Galaxy Nexus] Nutsonfire:
I admit I sort of got used to the lines etc even if I have horizontal ones too... still sucks for the money, nexus s screen was purrfect.

Still haven't given up totally on the idea of getting it fixed.
[Samsung Galaxy Nexus] kms108:
the nexus s also has them, it just didn't stand out, may be this screen uses HD technology, that why it show up well, this also goes for the galaxy note, it also has the same problem.
[Samsung Galaxy Nexus] Crazy CS:
S2, note and nexus have this issue....
[Samsung Galaxy Nexus] ChongoDroid:
These threads kinda suck
[Samsung Galaxy Nexus] kangxi:
You shouldn't accept defects as normal. My screen has no issues whatsoever. No lines, or grains. I wish people would stop these threads.

The thread title should say "MY screen sucks!" as this is not everyone's issue as the title misrepresents. If you want to see an example of how a perfect screen should look, I can show anyone my device in person.
[Samsung Galaxy Nexus] kms108:
you should rephase it, "You shouldn't accept defects as normal", it isn't a defect.
[Samsung Galaxy Nexus] kangxi:
It is a defect. What the OP is talking about isn't normal. I don't have any lines, discolored pixels, haze or whatever on my screen. Therefore there is something wrong with his screen.
[Samsung Galaxy Nexus] kms108:
use the app that i posted further up, and use the grey setting in a dark room, you know what i mean, you do see the line and grain, but some may stand out more, other may not.
[Samsung Galaxy Nexus] Jerry1130:
Can you post a screenshot of what a good screen is suppose to look like?
[Samsung Galaxy Nexus] kangxi:
I can take a picture of my screen if that what you are asking. I'm not sure how well that will translate as a picture but I will do it when I get home. I'll use the app someone mentioned above.
[Samsung Galaxy Nexus] kms108:
use the one that i have posted.
[Samsung Galaxy Nexus] platinumandroid:
Seriously I have no idea what the fuss is all about,My Screen is beautiful,do I see a bit of grainy ness, Of course sometimes I do,especially when the brightness is turned down but honestly it's only if you have the screen right up in your face & I'm not sure about you but I don't use my phone like that.If your unhappy with the phone & something bothers you that much then either return it or exchange it,nobody cares if you don't like your display or anything else about your phone for that matter.I never post about stuff like this but I am so sick of these types of threads filling up the forums.It makes it difficult for everyone who comes here for useful information and complaining about how you don't like this or that is just ridiculous imho.
[Samsung Galaxy Nexus] Shawn_230:
No issues with the screen here. Obviously if it was both HD and had an RGB subpixel arrangement it would look even better, but as it is it's not like you are being shortchanged for your $650.

Although I have noticed one weird thing about the screen. I have the flicker animation turned on and when I turn off my phone, the image turns noticeably yellow as it fades out. Not sure if that's the PenTile even...
[Samsung Galaxy Nexus] RogerPodacter:
There are 2 nexus phones at our Verizon store, one has a horrible screen and the other is perfect. So anyone complaining got one of the bad ones. Sucks.
[Samsung Galaxy Nexus] platinumandroid:
That may be true but opening a thread to complain about something that can easily be taken care of just doesn't make sense to me.
[Samsung Galaxy Nexus] kangxi:
You're absolutely right. This thread doesn't make sense and not everyone is having this problem which is what a lot of people have been saying.

I took pictures of my screen like I promised earlier. Both at minimum brightness and Max brightness. Don't know if pictures can convey what I've been saying but.

Enjoy

The OP said said red and blue looked terrible. Well, I think you could agree that red and blue looks perfectly fine. Only one that looked remotely suspect was gray at lowest brightness.
[Samsung Galaxy Nexus] Valynor:
You, Sir, need a new set of eyes. 8-)

After looking at your screenshots (the two low brightness white ones) I can clearly see grain, vertical banding and red/green colour shifting. More or less like on my device.
[Samsung Galaxy Nexus] jimbok:
+1

Especially the last picture, the grey color really makes the banding obvious.
[Samsung Galaxy Nexus] kangxi:
Clearly I mentioned that in my post. Is this an issue to me? No. If I have to turn my brightness all the way down and fill my screen with one color to notice something, is it really an issue in normal use? And btw those two bottom ones were dark gray, not white.

The OP seems to be having way more issues than this.
[Samsung Galaxy Nexus] Valynor:
I think this is what most people are angry about. A little banding and graininess at low brightness in whites and greys. They're not an issue to me either. I would prefer not to have the red/green colour shift on my device, though - but I can live with it and the gorgeous resolution makes up for it.
[Samsung Galaxy Nexus] bplewis24:
This is where I stopped reading.
[Samsung Galaxy Nexus] Drachnem:
I swapped mine out 3 times before I got one with a half decent screen. I don't get how Samsung makes the iphone 4s screen but then sticks us with this garbage.

I'm trying to keep it together because I know there will be a great following behind this phone, but the screen really is beat.
[Samsung Galaxy Nexus] WillEat4F00d:
I think LG makes the screen for the iPhone.
[Samsung Galaxy Nexus] EarlZ:
LG makes the IPS displays on the IP4, in terms of quality the IPS can be far superior compared to OLED but it wont have that much of a black level. Contrast wise they can achieve pretty similar results even my TN monitor can be calibrated enough to look almost like the HD SAMOLED but not on the SAMOLED Plus though.
[Samsung Galaxy Nexus] k.electron:
First world problem.

Get a nokia 1100, makes calls and texts, send the rest to donations to devs at XDA and in a few months the devs will have a custom screen to flash on ur phone.
[Samsung Galaxy Nexus] stevo101:
how about those that say they have good screen take some sample pictures, of a gray image or some video playback so we have something to compare to.
[Samsung Galaxy Nexus] G1-8701:
i really don't see what your talking about i love the screen on my Galaxy Nexus, and i'm coming from an Epic 4g Touch, and the battery is amazing, It charges super fast and lasts all day with heavy use. The Camera is great, but i guess it depends on the person, some people don't understand that no phone will be perfect but this nexus seems to be the phone i've been waiting for, massive developer support, guaranteed updated, pure android, great battery life, beautiful screen and camera, and a fast and dependable network(was with sprint on my Epic 4g Touch, now with Verizon) i mean what more could u ask for?
[Samsung Galaxy Nexus] EarlZ:
Because not everyone has the same level of perception or expectation.
[Samsung Galaxy Nexus] NuclearEMP:
If you took the iPhones screen and stretched it to 4.65" it wouldn't be all that great.

Take our screen and make it 3" or what ever the dinky screen is on the iPhone is and the amoled screen would blow it out of the water.

Amoled is designed to be bright, vibrant, super saturated, deep contrast, image popping beauty. You don't find all of those in other screens. Give this display some time and it grows on you.

I can't stand to look at other screens anymore. Would it have been better if it were a super hd amoled plus display?...maybe

But these things are the future of mobile displays and they are only getting better. Just bringing up the iPhone every time as a comparison drives me nuts because that phone is so over done. The only thing it has going for it is the apps and gpu.
[Samsung Galaxy Nexus] govindadas:
Are there some issues with the GNex screen that make it 'less than perfect'? Yes. In particular:

-it's ability to display 'clipped blacks' (blue/black crush, blue graininess, blue banding, etc).

-it's graininess/banding/flyscreen effect apparent on low brightness display of solid greys or blacks in a dark room

Overall, this phone has about as many manufacturing defects as any other phone, I presume. If the iPhone screen was scaled up to 4.65", would it look better? Probably.There may be a higher variation in this phone though. I'd have to read some iPhone forums to get a better grasp on the complaints there though...
[Samsung Galaxy Nexus] number3pencil:
Man, some people must have super duper vision or something. My screen looks AMAZING and it looked a lot better than any other phone I saw in the Verizon store. Only one that came close was the rezound.
[Samsung Galaxy Nexus] EarlZ:
Since I have an S1 and S8500, it makes me wonder why these issues didnt exist on those devices if they did its not this wide spread. I guess its because people started to accept these defects as 'normal' ?

You do realize that not all of the screens are 1:1 alike, there are huge variations between screens. If you got a great one then be happy!
[Samsung Galaxy Nexus] AllGamer:
the old devices had the good quality screen that was made by Samsung own factory in Korea

but since SGS2 and the shortage of SAMOLED "# version" screens, they started making them in the new factory somewhere in China

http://www.phonearena.com/news/Sams...on-of-AMOLED-displays-tenfold-in-2011_id13096

as usual China has lower QC (Quality Control)
[Samsung Galaxy Nexus] EarlZ:
Hmmm, I always thought all of these SuperAMOLED screens are made in Korea.. The article does not really point that there is a new factory in China ( or I missed it ) but its also a plausible reason why we are getting sub par quality.. chances are those w/o any screen issues are the ones made in Korea.
[Samsung Galaxy Nexus] AcE XBOX:
I honestly think all screens are a little different. I received my first Galaxy Nexus and the screen is great. Looked fantastic. I was having a data issue so I got sent a new replacement. As soon as I turned it on I could tell a difference. The colors seemed washed up and you can see pixelation when the boot up screen comes up especially in the back areas of the screen. With the first phone there is no pixelation on the boot up screen and it's a bit darker and you can see a lot less of the graininess.

I loaded up the dead pixel test app and it looks fantastic on my device. When I get home ill try the replacement phone with the weird screen to see how it looks.
[Samsung Galaxy Nexus] govindadas:
pure black screen test movie

play this video in a 100% dark room (probably need to turn your brightness all the way up). You will need to let you eyes adjust to the dark for a minute or so. This is 60 seconds of pure black, virtually uncompressed (indeo5) at 1280x720. You shouldn't see any of the blue crush/pixelation artifacts, just pure black. MX Video Player plays it, the stock video player won't (at least it doesn't for me).

My screen shows two small black splotches (about 3-5 mm in diameter) and some flyscreening. It's really hard to see, you really have to let your eyes adjust. The black movie looks more grey in complete darkness.

I'm curious to see what other people say. I've always thought my screen was one of the better ones, as it looks amazing, except for the flyscreening/banding on solid grays with the brightness turned down. Maybe mine is one of the problem ones...
[Samsung Galaxy Nexus] cmscritic:
Uh What?

What on earth are you babbling about? The screen is outstanding and easily blows away the 4s, which is a steaming pile of crap. <shakes head>
[Samsung Galaxy Nexus] EarlZ:
I should refer you to my post later on. I'm using a galaxy note tonpost this and my bookmarks ae on my pc. But I see the same issue on my note.
[Samsung Galaxy Nexus] kms108:
I dont think it's possible to get a pure black screen on a video format.
[Samsung Galaxy Nexus] govindadas:
I honestly don't really know the technical details, but I made a black 8-bit PNG in photoshop and turned it into an avi in matlab, exporting it to play 1 frame per second for 60 seconds. I would have posted the uncompressed version, but that is 200MB. I didn't see any difference between the uncompressed version and the indeo5 compressed version.

So I figure this is as black as any movie could possibly get, and as black as the screen will display without being off...

my laptop screen is actually brighter in the dark for sure.

Also here is a movie where you can see the blue/black crush/pixelation / black clipping effect. It's just pure black, but compressed by youtube (and the GNex video recorder -- I just recorded a video and blocked the lense). You can see some pixelation around the edges... again it's hard to see and you have to be in a completely dark room with your eyes adjusted.

*edit: Or you can just go in a completely dark room, record a video, and then play that back (fullscreen)... although it still gets compressed by the phone, and you will get the 'clipped black' noise/pixelation... another simple way to do a screen test. Then you can play that video on different devices to look for the compression artifacts.
[Samsung Galaxy Nexus] EarlZ:
It is google for samsungs slimness and lightness vid it has a pureblack scene a few seconds at starting point.
[Samsung Galaxy Nexus] player911:
I don't notice vertical lines but I do notice grainy grays when there is a alpha transparent or low brightness over a gray background. Big deal though.

Whites aren't super white when compared to my Asus transformer though. But beyond comparison, day to day the whites look white. Can probably be fixed with more of a blue color profile.

LTE EX Galaxy Nexus - AOSP KANG

Asus Transformer - 3.2.1 OC/UV
[Samsung Galaxy Nexus] EarlZ:
The rgbg pentile can't produce whites like lcd even if its calibrated its either gonna have a yellow or blue push. The whites on the samoled plus are great though.. if the next galaxy note comes with rgb stripe or rgbw it might prove great.
[Samsung Galaxy Nexus] Jayrod1980:
To all gamer, your assumption about the Korea vs china thing is totally false. First batch was all made in Korea and by far had the greatest amount of defects as they were still ironing out the bugs in manufacturing process. A great deal of the later ones are made in china and have been reported to have much better blacks and less banding. I cursed when the daily steals bought model I got said made in Korea. Just because its been made in a country known for quality doesn't automatically mean it is good. If you ever had a mytouch4g, they had a good screen version made in china.
[Samsung Galaxy Nexus] EarlZ:
Mine was the first batch and made in korea no issues. Both on the galaxy s1 and s8500. My s2 was made in china.. all 7 all different defects.. my note made in Vietnam and also has issues. Although I understand your point but my experience contradicts your statement.
[Samsung Galaxy Nexus] @work:
Phone must be broken.
[Samsung Galaxy Nexus] Soutaiseiriron:
Why would the location of where it's manufactured affect the quality? Isn't it just Samsung making it in china?
[Samsung Galaxy Nexus] PeXda00:
Apart from battery drain when using it hard.. These complaints seem very petty or BS. Perhaps there was a bad batch??

Held it next to iPhone4 screen, found that iPhone4 screen may have better colour accuracy in some cases but that's where iglory ends. Contrast, Sharpness.. no contest. Silly comparison to say the least.
[Samsung Galaxy Nexus] AcE XBOX:
No joke. The one I kept because the screen was dramatically better is made in China. So I pulled out the one I am going to return and it's made in Korea. Thanks for the input! The difference between these two phones are dramatic.

Made in China Nexus is the superior version.

EDIT: I'll try to make a video so you guys can see the difference.
[Samsung Galaxy Nexus] RogerPodacter:
I keep saying, samsung switched their amoled screen production to new equipment line in order to make higher res amoled then the previous phones. The note and nexus are likely first 2 production with this new equipment process, and these are side effects of it. Thats why we've never seen it before. Likely will improve with future production.
[Samsung Galaxy Nexus] EarlZ:
Can you link me to that information source?

None of these issues are actually new.. lines,blotches,uneven brightness,poor viewing angles, spots on gey and black are issue already heard on the galaxy s2. Lines were quite rare on the s2 though.
[Samsung Galaxy Nexus] biffsmash:
Question thread that is actually a statement, and an incorrect statement too lol

Nexus screen is best on mobile by far. All screens have their issues as nothing is perfect.

On nexus and sgs2 its hardly noticable oddities at low brightness, on iphones its washed out blacks and size.

Fact is, loads and loads of phones are 500 quid a pop these days, doesnt guarantee them fault free.

Cars are thousands but all cars have issues that annoy us.

As for colour reproduction and whites, hogwash! Iphone whites are no where near real white in my book.
