The Nexus S had a completely black screen - at night black was no different that if it was switched off. My GN appears to have slight screen glow in the backs. However, I thought they were both SAMOLED screens? Presume I am wrong? Can anyone explain?
/R
I noticed the same thing. I just assumed that not all sAMOLED screens are equal, and that the change in resolution could have been a cause. Maybe Samsung wasn't able to perfect it. Just speculation
It is pretty close though.

I was expecting this too and was a little dissapointed, was looking forward to having my night clock on and the only light coming from the screen to be the clock text but the whole screen has a slight glow to it
Same here, I wonder why is it like that. No bragging of true black anymore. Feels like step backwards.

The screen does do true black.
It's just the wallpaper isn't turned to black, it's made very dim.
The "slight glow" is the dim wallpaper if you look carefully.
Hmm, I made own 1x1 black picture for background. Still it isn't true black.

The same here, not nearly as black as my old Galaxy S
The blacks look black as black to me.
Mine seems pretty black. I've only had a Vibrant with SAMOLED before, and I think this is equivalent if not better. Sadly, I've got a small weird green dent on the pixels on the second quadrant though...
I've noticed this too. Definately not as dark as my Galaxy S2 was.
My blacks look as good as my GS2's did to my eye. When you guys open up the app drawer, it's not totally black behind the icons? I can't make out bezel or screen with blacks.
I've also noticed that the blacks aren't as black as on my Galaxy S. The blackness on the GS was even more noticeable since every colour displayed is eye-burstingly vivid. I do miss the true black but at least the general display is nicer on the GN than the GS.

I just used the night display mode on Gentle Alarm.
I put the Galaxy Nexus and Galaxy S2 side-by-side.
The Nexus definitely has a noticeable backlight compared to the S2.

Well the nexus doesn't use any backlight. Which is odd because there is a definite glow, I wonder if some screen tuning can remove it

Nigel Tufnel: It's like, how much more black could this be? and the answer is none. None more black.
I hate black screens I only like white ones....yea i said it!
My screen is as dark as midnight and is peferectly fine with me.
Can people please who say screen is completely black test the clock app in night mode in a perfectly dark place. I have a feeling this is not only in some of the phones but in all. Will contact support to verify this.
I think the black tint on the glass isn't as dark as it was on the nexus s. At least that's how it looks on my gnex.
When the screen is on for an AMOLED display, it's not "true black". If I remember correctly, there's a minimum voltage applied when the screen is on. Otherwise it would draw more power to switch the pixels from fully off to on. In other words, the GN might have some slightly different minimum voltage.

As mentioned earlier, the clock app doesn't use a pure black background. Rather, it uses an dark overlay over your wallpaper.
Also, the default background for apps has been changed to one that isn't pure black

Turn off autobrightness and set it to 40% and it should be less obvious.
yup it's a common side effect of all the SAMOLED displays
it's less obvious when you have the brightness at around 30%
the only phone that doesnt is the nexus s.. because google made the color a little yellowish in an update. Maybe its the rom, or maybe i dont notice it anymore, but beastmod v3.6 seems to have white whites

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.

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.
On my Galaxy Note 2, if I display a pure black screen in a completely dark room, I can see that first of all, the "black" is not really black, but somewhat pinkish. And second of all, there are "really black" dots and lines across what is supposed to be "pure black" but is somewhat pinkish (like i said). Also, this effect, of having a darker line, can also been seen with say, dark blue on screen in a completely dark room.
This effect is not noticeable when white or other colours are on screen. I'm really sorry but I can't show you a picture of this because obviously a screenshot captures the digital signal and not the physical output and I don't have a good enough camera to take pictures of what I'm saying in complete darkness.
Is this a defect or just an unavoidable "feature" of Samung AMOLED screens?
you did not use the search function: i personally wrote a huge amount of posts regarding this, also in the note1 section!
search for "black blotches" or take a look at my posts. really lots of them are about this!
in short:
its manufacturing dependant and its luck of the draw to get a "good" screen!
samsung lives with this as not many customers complain(ed) about it, as most of them do not even notice it!

Mine is pure back at full brightness when seen in a dark room (no pinkish hue or any line that you mention). And Note 2 screen doesn't even have the infamous black clipping/crushing issue like its predecessors! Blue colour also good, no issues for me.
No, it is definitely not an AMOLED feature or drawback (never seen it on any other AMOLEDs either)! Of all other aspects samsung SAMOLED screens are known to have the deepest blacks (with best contrast ratio). Sure, it sounds like you have a defective screen, and my suggestion would be to get it checked up at SC for replacement.
i also have a similar issue on my note 2. a black screen is not completely black, but a brownish black. And i can see 3 (or more) dots which are completely black.. i can see this only in a dark room, so normally this is not an issue. But when i read kindle in my bed with dark background, this really bothers me. initially i thought this was some smudge on the screen. im sad to hear that other people are also having this issue..
I had the black dots on my galaxy s2 ... but not my note ... The screen on my note has none of that sooooooo happy about that it really is just luck of the draw ....
