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
Hi everybody.
I bought my Nexus in December, and some time ago I noticed that screen looks ugly on certain backgrounds, mainly gray ones. So I did a little investigation and it turned out that I was right: picture looks mostly okay on primary colors, but grays shows terrible smudging. I took a photo of it. Do you think it qualifies for a warranty repair? Any of you noticed something like that?
I attach a photo, it's out of focus on purpose, because otherwise there would be a rainbow goo on screen.
The screen doesn't look good at lower light with certain colors that's just how it is..
The smudges look like someone wiped the screen with their thumb.
Screen was cleaned before taking photo. This rainbow effect is more or less visible on any background, but gray is especially bad. Even scrolling webpages is a bit annoying, because starting from top there is a pinkish stripe, then normal, then pinkish again... Yuck.
i have the exact same problem! Gray and white is the worst, and lower backlight is worse. But I realized this is mainly the glass top's fault, while i scroll a page, i can see those sumdges staying in the same spot!, don't know whether a protecting film will help or not.
joshdu1125 so I'm not alone then. I had a protective film on screen until yesterday and removed it because I hoped it was it's fault. Turned out it's not. Contacted Samsung via email, wonder what they will say.
Handtec said that some of the first phones (first batches) have worse displays than newer batches. I already sent my phone to them to be replaced.

screen issue
looks like its more or less same problem experienced by G.Note user, like myself..
G.Note Screen Problem Thread
try get "screen filter" from market and lower the intensity of color to let says 30%, check that same grey image, how does it look?..
My screen is much worse than urs if u wanna see... =.="
I am starting to think this problem is universal to all Samsung devices.. Zzzz
unfortunatey this is a problem with all samsung devices i suggest getting a kernel with color control such as francos or glados. its a lot better then the color control filter app and runs super smooth , francos kernel also pretty much doubled my battery life.
rey5757 you are right, less brightness = problem more exacerbated. I you have a photo of your screen, let us see it.
amcmearty I'm using Franco's kernel right now, but tried others too, to no avail.

just go to G.Note thread in my last post, at page 65. I don even have to take "out of focus" photo to see it.
This is a problem with the screen at lower brightness levels.. it happens to just about everyone that greys and whites look bad.

The problem with this shadow thingy is that is varies greatly on difference screen.
The "Size", "Darkness", "Area" of shadow are INconsistent. Some screen have shadow on top area of screen, some have it at corners, some have it at lower bottom, some have it all over half or screen. Then some have it but barely visible(maybe this fall in perfect screen category), some have it but extremely obvious..
How is all these random quality screen fly out of Samsung?..

¿Samsung? No thanks: P
I'm considering getting the S3 but Im worried about screen burn in. I'm the type of user who uses the lowest brightness possible. Should I worry?
I don't think burn ins are a concern with these screens. I left my screen on on a few separate occasions displaying a single image for over 7 hours each time with no problems so far.

I wouldn't worry. You need a still image to be up for an extrenuous amount of time. It is possible though, but you'd almost have to try. I haven't seen any posts with users with screen burn either.

Does using the lowest brightness possible reduce the chances of this happening or it doesn't matter?

Use auto brightness.. and set the screen to turn off when your not looking at it.. my S2's screen was messed up but so far with this phone nothing

Yeah, you never see much complaints about it but it's definitely possible. I'm going to guess it's less possible than previous version of the AMOLED displays. On my samsung infuse after 2 years of using the AOSP android keyboard, I could somewhat see an imprint of the keyboards keys whenever a dark-grey image is displayed on the whole screen but it was extremely minor.
You will get some burn-in with AMOLED after a few years no matter what. Pentile AMOLED (in the S1 and S3) is also superior to the AMOLED+ in the S2 for longevity, or so says Samsung.
My 2-year old Captivate has some up top where the notification bar is, and on the bottom where the keyboard is, and where the high-contrast black&white WordFeud game tiles are that I always play.
The burn-in ghosting isn't THAT noticeable, though, unless you're viewing mostly white images or webpages.
S3 do have burn ins just to let you know. Download screen filter and lower the filter to 10% or maybe 0% and you will see imprints. or download dead pixel test and the second color will show also all your burn in.

Hello,
When i have a wallpaper whit black on top of the screen, then i have a small black line on top were normally the status bar ends, so thats a half centimeter from the top screen.
Its really difficult to see and its only when i have a really black background,
When there are other collors then the black line is gone so its only with really black.
Maybe that its normall
Thank you
Best regards

I can only see it when its darker in my room, so on a clear day i dont see it.
I have the screen setting on standard and the brightness on 25%
So its about 1cm below the samsung sign from left to right
Further than that the screen is really perfect
Sorry for my bad english

I don't have one yet but it doesn't sound like a faulty screen. A faulty display may have pixels or a row that is all black regardless of what's on the screen or always white etc.
You can try downloading a screen checking app, it will display all black, white, red, green and blue to try and identify faulty pixels.

Hello,
I have checked it with the app screen test.
I only see the small black line when the screen is full black in the test and i must be in a darker room, the rest of the test is perfect from dark grey to every collor
Maybe someone else can test it to with the app screen test, i would appreciate it
Thank you

If that is the case something may be wrong. While it isn't a typical problem it should not be occurring. Consider getting a replacement.
Hello,
Do you think its faulty?
Is it not normal like the black spots on the note 1?
Sent from my GT-N7100 using xda premium
If you see a black line that goes across the whole screen and it is only visible on a black screen that is defective in my opinion. It should be consistent.
No its not from top screen to home button.
The small black line is on top were the status bar ends so its a horizontal line when you hold the phone like when your calling.
Yes its only when there is full really black picture or movie
My note 1 from last year had alot of black spots over the whole screen and that was only when there was black screen
Sent from my GT-N7100 using xda premium
I don't really have any experience with AMOLED screens but it still does not seem normal to me(I could be wrong). It really comes down to if it bothers you and how noticeable it is. It probably isn't too bad since its only for black.
Why don't you take a screenshot from your phone (Press the S-pen button, then tap on the screen) and then transfer the image to your computer.
Compare both images and if the black line doesn't appear on your computer, it means that your screen is faulty.
I can do that.
Is there nobody with a note 2 that can test it maybe whit the screen test app, and then go to the full black screen and look good for a black line, but with normall light its not noticable you must be in a darker room
Sent from my GT-N7100 using xda premium
I had exactly the same issue with S2, sent back for replacement. It was very noticable with black backgrounds and also whilst using camera in dark situations, other than that is was very difficult to see.

Yes i have seen pictures of a s2 that was really terrible, alot of black spots and line over the whole screen.
Did your new s2 have it to?
My note 1 had black spots, almost every note 1 had them so far as i know.
Now there are no black spots just 1 small black line so its not mutch, and its only noticable if i am in a darker room with full black screen.
I have read that its a amoled thing, and almost all amoled screens have it, some worse then other

Did you not tested it or do you mean you have no small black line?
Thanks for the help!
What do you all think:
Is it just an amoled thing, that is what i have read on the internet
Or
Is it a defective screen?
just return it for an exchange if it bothers you.
I can do that but if its just an amoled thing then the new one will have it to or maybe worse

It is an AMOLED thing.
All will have it to some extent, some more than others.
I can see a small 1cm line on my s3 screen in darkness with a dark wallpaper etc, but it doesn't bother me as I only see it in extreme circumstances!

Hi,
I have an issue with the screen of my Gnex.
I tried to post the question in this thread http://forum.xda-developers.com/showthread.php?t=1394358 but i received still no answer.
My Gnex had a yellowish tint on entire display, but i have resolved the problem setting up colors with trickster mod.
The issue is that the top half of the display is a bit darker than the bottom half, it looks to be a little yellowish than half bottom.
It can be seen on a completely white background.
I noticed also that looking at the display at about 45° from bottom to top the color seems to become uniform.
Can be this problem due to the fact that the touch screen is curved from the half to bottom and not from the half to top?
The display itself is just flat and this may create a sort of refraction thru the touch glass.
I was not able to see a brand new Gnex till now because i buyed mine by second hand.
What about your gnex device?
I would like to know if it's a real defect or not because I have to decide buying a brand new replacement display.
Thanks you in advance for your answer.

I have found that my purple tint is more purple at the bottom, where the navigation bar is, might be a similar thing. Best thing to do is just to live with it, it's probably a OLED issue

Galaxy Nexus has content adaptive brightness turned on by default for the screen and the messaging app is white, apps like facebook are a light color as well. So when you pull up the keyboard, the total white color is reduced and the one that is left is turned up to a higher brightness. Which causes faster degradation of blue oleds on the top half. Turn off content adaptive brightness in trickster mod to prevent this from happening further.

Thanks for the answer, i had already disabled the content adaptive brightness, but the strange thing is that the top area where there is the notification bar is more yellowish than the area where there's the navigation bar when I hide them. Both bars generally are black for the same time but the pixel degradation seems to be different. This made me thinking that the color shade is due to a sort of refractive effect due to the curved glass. As I wrote previously, looking from bottom to top at about 45 degrees the solid white looks to turn uniform.
I also changed the color of the keyboard to white to avoid to use different colors on both top half and bottom half.
Also disabled the crt animation because this burns a stripe in the middle of the screen. My brightness is always set at 20 percent.
Thanks very much for your suggestion anyway
