I'm calling all the GN owners to check your screen to see if you could duplicate the same issue I have on my TWO GNs.
Step:
1. Manually set your screen brightness to lowest brightness.
2. Go to a complete dark environment like in your closet or test this at night with all the ambient lights off. Again in a COMPLETE DARK ENVIRONMENT, this is crucial to duplicate the issue.
3. turn on the Camera app and look at the screen.
After your eyes adjusted to the darkness, you will see a bunch of nasty scattered pixel blocks. It's like pouring inks on your screen.
This pic says it all. From forum member sunnyshirz from this post:

Both my phones ordered from expansys-USA and Negri Electronics have the same issue.
I do this about 7 times a day, it has to be a common use case right?
Seriously, do you see the insanity of recreating this non-problem? Just think about it.

The screen image attached to the OP of this thread also suffers from the same issue:
http://forum.xda-developers.com/showthread.php?t=1366878&highlight=test
How many more of you have this?
I haven't checked mine yet. But I don't really use my phone in the closet with the lights off, so for me, and how I use my phone, my phone kicks ass
I did use it on lowest setting with light out in bed last night for a few mins, and saw no dots. So it probably has something to do with the camera and what it is seeing in total darkness. Since it is not an infared camarea, I see no problems with that either
I tried this and couldnt see spots, mine does have the right edge slightly tinted issue though. All amoleds have variations theres over 200 pages in the galaxy s2 forum.

If you set your wallpaper to black/grey you will see it at your home screen.
I spotted this issue when I was playing with my phone before bed, it is definitely not a Camera app issue, it's something hardware related. Like I said before your eyes need to adjust to the darkness in order for you to see those dots.
This is pretty annoying if you use your phone at night with all lights off.

It's true that during normal usage in daytime you cannot see them, but I use my phone in dark environments a lot so this is crucial to me.

I have used my phone in the dark a bit. Kindle app set on black bg with brightness turned all the way down is the largest. I always have the brightness all the way down when using phone at night in bed so not to bother the wife. Have seen zero issues.

My first nexus had many stripes from the bottom to the top but my second one is much better.
Sounds like a classic case of someone looking for a problem. If a person has to take all the steps the OP described to recreate a problem, then it isn't a problem. Nothing to see here.

This is correct. And I think an easy solution would be to put the brightness at 15-20% instead of the lowest so you don't see whatever it is you see
try installing dead pixel from the market then check it that way. My is solid black, no bleeds at all.

This.
You can pretty much obsess over and examine any product long enough until the following realization occurs:
OMGDEFECTIEVE!!
It's really unfortunate that the OP cost the retailer/Samsung money going through a few phones for an obsessive compulsive microscope discovery about a real non-issue. Results in higher prices for everyone.
Ridiculous.
I think here's how you get to the bottom of this. Go online and google search absolute black. Save the 7th image on your phone. Then go to the saved image in your gallery and zoom in on the top left corner of the picture while in a completely dark room. If it looks weird, then your phone may have a problem, but if not, then STOP LOOKING FOR THINGS TO HATE.
This is a great phone, why try to ruin that. My guess is that the issue you're seeing is because of the camera. It's horrible in lowlight settings.

I don't have a GN yet so can't replicate your method, but if it happens when you use the camera app, don't you think it could have something to do with the camera? The camera gain will be all the way up in total darkness which will produce weird pixelations.
If you're trying to get solid black on the screen to evaluate the display, I am sure there's an app that can do that. Or simply make a web page with all black.

Hah!
Same thing with my gsalaxy s2. There are also other "strange" effects on gs2 screen at lowest levels. I think I saw something like that at note subforum. So I guess it is more or less normal for every amoled screen.
I can reproducethis issue, but I never experinced it in day to day usage. It is no problem for me.
Ok guys. Thanks for all the negative comments.
If your phone has no problem then good for you. I couldn't stand for this issue because I can notice it fairly easy in low brightness condition, I have tried to increase the brightness to around 40% and I can still see it. And again this is not a camera caused problem. I first noticed this when I was using Google Music to play some songs at night. The problem pretty much exists under any pure dark background.
Please look at the pic I posted, Does this look like "normal" to you guys if you were in my shoes?
This is an AMOLED issue. Just keep the screen step above minimum and its completely fine. Phone is not faulty, that's how that screen works. AMOLED is also more noisy on lower brightness, that's not a faulty screen.
I don't have this issue. My screen looks great and is from Expansys. What do I win? Your phone does look pretty bad though, maybe exchange it again?
I dont understand why these newer screens just look worse in coloration to me. It seems like all these new phones have a blue or green tint to the screens. I went to look at a Epic 4g touch in the store today because I love the form factor but the screen doesnt look as good to me. Is this fixable with some sort of calibration? Or is the hue always there? I want a new phone but I dont know what to do! I like the screen of my old one more!
What say you XDA experts! Looking forward to your responses!
I think you're 100% right. I remember comparing my old G2x screen to the display unit at the sprint store and being quite turned off by it. It even took me a few weeks to get used to the "bluish" color of the Epic... however.. I do so love that deep black. Wow.
Aagghh! So there's just no way to fix it? Seems like the only neutral screen these days is the 4gs

Check out "Screen Adjuster" by Netman in the market. It let's you adjust the RGB values of the screen, as well as the contrast.
Watching videos on the GS2 is very hard on the eyes if there are a lot of dark scenes... Most of the detail gets lost because of the deep black, even with the brightness turned up to 100%. This app lets me crank up the contrast as well so I can actually see detail in dark scenes.
Essential free app, in my opinion. It can be set to autorun at system startup, or you can run it on demand (that's how I use it).
Any way someone could post comparison screen shots? Would be interested to see how neutral one can get it. Also does using that program cause more battery drain?

There's a setting to adjust the colors to make it less saturated. Lighter colors especially white will never be pure white, then again there is no true black on an LCD

Before I used the program, I could watch 2 full-length movies streaming 3G via Netflix and still be at 45-50% battery. After I started using the program, my battery usage didn't seem to change, at least not that I've noticed.
I apologize if my attempt at search terms didn't yet yield an answer that has already been posted.
On my Droid Charge if I tilted the phone up or down in portrait mode it would cause the screen to take on a blue hue. It turns out it was because of the screen protector I was using. Took it off, no problem.
However, I have no screen protector on my Galaxy Nexus, and I'm seeing the same thing occur. Since the screens are hardly the same (AMOLED+ vs AMOLED, different resolution, different size) I can't really tell if its normal. The demo model at my store was out of commission.
Anybody else notice this or is there something wrong with my screen? My friend said his doesn't do it, but I haven't seen it myself (he lives an hour away) and its possible he just isn't as picky as me
Thanks in advance.
I got the same thing on mines. Blue tint when not looking at screen straight.

A blue tint of some sort, or cool colors in general are a product of the Super AMOLED screens, yes.
I don't think Voodoo Color would fix it in this respect, because I think it either has to do with the coating on the screen itself, or the way the light is refracting based on viewing angle.
I could be wrong...
Previous to my GN, I've had a Nexus One, Nexus S, and Galaxy S II (international version) and on all of the phones black levels were pitch black and no different to the screen being completely off. Despite still being an AMOLED display, it seems the GN's screen can't do pitch black.
As a test, go in a dark room and open the clock app. Long press anywhere on the screen and the clock will go into night mode where it will be a completely black screen with just the time showing. You'll notice that there is a still a bit of light emitting from the dark spots.
A little disappointing... I wonder if this could be fixed in software.

It can do pure black but not everything is pure black. I just rebooted and say the Google boot image. Its solid black. I'm in a dark room now and can't tell a difference where the soft keys end and the case begins.

Actually that's just the clock app, you can easily see that it's an extremely dimmed version of your wallpaper. My wallpaper is this http://cooldesktopbackgroundsx.com/wp-content/uploads/2011/02/34327523.png
and I can easily see the eye in the dark mode.
I don't see how your background could make a difference. Night mode is completely black. Just look at the screen shot.
I can also notice this when first booting up and see the Google logo. It was the same this on two other units that I looked at, so I don't think it's unique to my phone. To truly notice it you have to be in a pitch black room. I only noticed it because I was using my phone as a bed side clock.

The whole point of AMOLED is that each pixel is it's own light source which can be completely turned off. True black was possible on every AMOLED phone I've ever used prior to this one.

That is exactly correct. Fortunately, at very low brightness, my GN does indeed display true black. I have an all black background and if I cover the time, I can't tell a difference between the phone off and on. Keep in mind that true black only occurs under extremely low brightness. Turning the brightness up introduces a bit of light polution.

No, no... I've owned the Fascinate on Verizon and when in complete darkness you can see a little bit of light emitting from the screen. The Gnex just has more pixels so there's probably more light emitting. But the blacks don't seem to be any less black than my Fascinate. When you turn the screen on the pixels must be excited in order to know when they must turn on or off, this will still emit a miniscule amount light.

I'm sorry but you're TERRIBLY mistaken and I wish this thread would get deleted before you confuse others! Night mode is simply DIMMED. It is NOT 100% black, but transparently darkened. There is a really easy way you can see this for yourself, simply turn on an animated live wall paper and go into night mode in the clock. You'll se the moving live wallpaper in the background in the "black" areas. That screen shot you took is showing the TRANSPARENCY where it's black. It is NOT actually black there!!!
The GNEX screen is JUST as black as any other SAMOLED Screen if not even more so! If you want to see 100% black - just boot into clockwork mod recovery! the entire background ther is 100% black and you'll see how inky black it looks! That said the status bar at the top of the screen is also black, and blends right in with the bezel.

What are you smoking? Download that screen shot and check thd color yourself. Its #000000, meaning BLACK. The only confusion is with people not knowing how to go into that mode in the clock. LONG PRESS, not just a simple tap.

I guess the comment that there is always a minimum amount of power in even the black pixels could be accurate.

Yes. From what I have read (OLED information, a few book selections, and an interesting patent) sAMOLED displays include what is called "pixel pre-charging".
This is due to the fact that it is far easier to precisely control the pixel, which corresponds to a "drive voltage", when the starting point is a pre-charge. Its faster and more accurate. However the pre-charge causes light to be emitted. There is no avoiding that. As much as people say "my nexus s/galaxy s/galaxy s 2 have pure black", there is NO SUCH THING even on a sAMOLED display. Contrast ratio for the Galaxy Nexus is 100,000:1 rather than infinite.
Hi, just wanted to put this topic to rest.
Was somewhat disappointed in the screen performance of the Galaxy Nexus, coming from an Galaxy S2. However I reckon it is an issue that can be fixed with drivers.
The blacks on the Galaxy Nexus are far from as good as the SAMOLED+ panel on the SGS2.
Here are some pictures of them side by side with the clock app set to night modus.
Not a deal breaker for me, but I hope this is improved in future updates.
PS: Sorry for the big-ass pictures..
my screen is blacker than the bezel..

What is your wallpaper, cause I think I can see it in the second to last photo. Like stated above, the clock is only a semi transparency over the wallpaper. Run a screen checker and take pictures of that black, that would be a better test and example
Edit: in all likely hood its just a calibration issue. Franco's kernel improved whites and colors significantly over stock. Personally, I can see that its not 100% black at the moment, but it is 99.999% black. And 100x better than backlit

The technology switches off the pixel so there is no blacker than that if you are not getting pure black then something is wrong most probably the wallpaper is not really black.

Ok, I have just noticed this, not sure what it means. but it's something that can be easily tested by everyone in a few minutes.
While in gentle alarm in nightmode. the screen is all black and the digital clock is shown, I noticed black lines across my screen and really black dots peppered all over the screen, mostly at the top closest to the earphone. I'm thinking they are dead pixels but not sure.
To reproduce it, I downloaded SBMX, a paint app like photoshop. I painted the canvas black, turned off the lights and after my eyes adjusted, I can see the same pattern of black pixels all over the screen. there is one line near the top of the screen that goes right across.
If some people can try this and post your results it would be very appretiated. If they are dead pixels, I will return the phone.
If they were dead pixels you would see them no matter what color the screen was.

It's how the screen technology is.. we had a lot of threads like this a while ago.
The conclusion was: "When are you ever going to be looking at your phone in pitch black, on a black screen, with the brightness set to 1?"
From what I have read it has something to do with Super Amoled and the glue used.
My Nexus is not near as bad as the Razr I had. Check out the Razr thread on this.
Ocassionally I would notice on my Razr when using the phone at night, without having to "look" for it.
I can honestly say that I have to try hard to see this on the Nexus, and I have never noticed it in general use, even at night. It shouldn't keep you from enjoying your phone!
edit: so much for that build quality argument they keep throwing around
lol had to say it.
I noticed this on mine in bed the other night ,it is all along one edge in landscape mode. can't see it at all in normal use though...
