[Samsung Galaxy Nexus] bongadadu:
Hmm, won't be buying that lol.

Maybe I'm paranoid, but in a completely dark room, on a pure black wallpaper using 100% brighthess the bezel looks blacker and it seems as if there is some backlight. Any one else getting this?
[Samsung Galaxy Nexus] :
Yeah I think that's normal. I've had 4 of these phones (so many screen issues, I'm finally settling for the least annoying of the bunch) and they all display this characteristic.
[Samsung Galaxy Nexus] bongadadu:
Why is that though? Is it due to some reflection caused by the screen glass ?
[Samsung Galaxy Nexus] Nikke_2:
I have corrected color balance using application "Screen Adjuster 1.6"

(it's free application)

Settings

Red +0

Green +0

Blue +6

Now the color balance is much better for me :)
[Samsung Galaxy Nexus] chjade84:
I am not getting that - in fact, often my bezel looks LESS black because it reflects ambient light. I set my brightness to 100% and turned off the light on the microscope and this is what I got at the edge of a picture in the gallery - single thumbnail with the rest of the screen black background.

Since there physically is no backlight and each of these pixels is essentially a tiny LED there just can't be any light bleeding through. Maybe your background isn't 100% black? Do you notice it in the background of the gallery album thumbnails? That's 100% black and is where the above picture came from.
[Samsung Galaxy Nexus] :
Don't get me wrong... It looks really black, but even in an all black page on pixel tester the screen still has more luminance than when it is completely off.

Edit:

Interestingly enough my galaxy s (fascinate) displays this property, but is much much darker than the galaxy nexus. Overall the nexus has a more yellow cast, and in my opinion, a SERIOUSLY worse screen in every regard except resolution than the fascinate. As I said before, I've compared my nexus with several others and have actually had three other phones so I have no reason to believe my unit is out of the ordinary (It is possible however that over 50% of the phones are defective and I have never seen a good example). Interesting stuff... I'm really disappointed with this screen.
[Samsung Galaxy Nexus] chjade84:
What pixel tester are you using? Perhaps it illuminates the pixels very slightly vs having them completely off?
[Samsung Galaxy Nexus] Flash728:
the reason that you do still see some "backlight" when the screen is black and on full brightness is because of the TFT backplate used in the Super AMOLED display. The transistors used need to still keep a "slight" charge in order to redraw the images on the screen faster, otherwise there would be a slight delay in you doing something on the screen and the screen actually drawing it. So that slight power going through the transistor is causing that slight glow you see on an all black screen. I belive that the reason you cant see the "black" pixels in the OP's picture is because the camera adjusted for the brightness making the really dark pixels look darker to prevent the "bright" pixels from being too bright. I know this seems like a dumb source but i got this info from wikipedia lol
[Samsung Galaxy Nexus] :
That seems to make perfect sense to me. I wonder why it's more pronounced on the nexus though...
[Samsung Galaxy Nexus] chjade84:
While I'm no Wikipedia-basher I don't think the TFT backplate thing would *normally* cause this issue. But since you made me doubt myself (and I currently have nothing to do at work) I got out the DSLR and the optical scope in the lab....

With no illumination and 10 seconds worth of exposure I still don't see ANY light from the pixels. I'd post the resulting picture, but it's nothing but black and noise.

EDIT: Here it is. Left is 10 second exposure unadjusted - right is with the Exposure, Brightness and Contrast upped enough that you can start making out the edges of the pixels. If the camera couldn't catch any light I doubt a human eye could.

Once I turned on some side illumination things got interesting...

The upper portion is illuminated while the lower portion is black. I don't see any light from the lower part at all.

LED's have a minimum voltage before they start to light (e.g. 1.0V = off, 1.1V = off, 1.2V = off, 1.3V = 5% 1.4V = 10%, and so on). If I were a betting man I'd say that the voltage wikipedia speaks of is probably close to the threshold but just not quite enough to cause illumination. Perhaps he keeps getting phones with slightly low tolerance resistors that let that voltage get just past the threshold.

Who knows...
[Samsung Galaxy Nexus] kms108:
about the black colour, the led display should completely be turned off, does this only happens to a 100% pure black or all black shadings, also can you comfirm that the black walpaper is 100% pure black, and not just black, isn't it impossible to distinguised 100% pure black with the naked eye.

if you dont want to answer this, it's fine with me, it just suddenly pop in my head.

thanks
[Samsung Galaxy Nexus] qwho:
I've never gotten the screen completely black at night. When on, the edges are noticeable, no matter what you display on the screen.

I will try the gallery later tonight to see if it was just that I never actually had a black screen displayed. Maybe someone who has this perfect black screen, make us an image that is the correct blackness that we can view and all try out?
[Samsung Galaxy Nexus] chjade84:
Here you go. Pure black. #000000

EDIT: I have tasted my own medicine. I went into a virtually 100% dark room and am seeing the background as slightly more grey. If I crack the door and let in a little light it turns back to almost pure black. But that's with the navigation icons and the status bar still illuminated and I'd bet that that light is enough to illuminate the glass which would make your blacks appear less black.

More testing must be done!

lol
[Samsung Galaxy Nexus] kms108:
are you talking about pixels or actual spots or patches.
[Samsung Galaxy Nexus] remedy1978:
Yes, I have around 20 black dots, not pixels. They don't show up unless I am looking at a completely black screen. This of course makes it difficult to enjoy any videos or movies because they stick out like a sore thumb. :(

Google is suppose to send me a third Galaxy Nexus so I will probably compare that to the one I have now and keep one or the other. I do not have the energy, time, or patience to keep swapping these phones.
[Samsung Galaxy Nexus] thetrailofdead:
I saw someone mention it earlier, if I rotate my phone and there's a white background, I see a green tint where the status bar used to be. Is this a prevalent issue?

Just did the test for dark spots in a dark room. I have some as well, but they were hard to spot and it took a little while for my eyes to adjust to notice them, but they're definitely there.

Edit: now that: know the dark spots are there I notice them. Three streaks and some spots :(
[Samsung Galaxy Nexus] jeNova-:
I got my Nexus like 30min ago, played around with it a bit so far.

First thing I did was settings brightness to 0 and going to a dark room to see if there are any purple / yellow tints and stuff like that.

And my Display seems to be very fine, the black is totally black, the white is a bit grey'ish and grainy but its not that big of a deal, overall it does not look as colorful and sharp on low brightness, but as as I see on the first page thats normal and imo its okay I can live with that since its only on low brightness anyways.

Either then that I didnt noticed any errors so far, so my display seems fine.

And overall I love the display, its sharp its clear and the colors are amazing!
[Samsung Galaxy Nexus] Alexander T.:
Can you please check if it has a slight green tint at the bottom part of the screen as compared to upper part on low brightness gray or white backgrounds?

Also, please, tell us the production date. See manual on how to figure it out: http://xdaforums.com/showthread.php?t=1519606
[Samsung Galaxy Nexus] brian515:
I got my phone almost a week ago from the Play store and I really love it, but I think I have a green tint towards the top of the screen, some black streaking, and the image retention. I'm not being too picky in getting a replacement for this, right?

It won't let me post links, but if someone would take a look at these I'd be really grateful!

The first picture is completely white at the lowest possible brightness with 1/30 shutter, and the second one is completely black with a 2.5" shutter.
[Samsung Galaxy Nexus] kms108:
people can click on the link now.
[Samsung Galaxy Nexus] jeNova-:
No I do not have a slight green tint, at least I cant see one.

And I dont know the production date, cant seem to find that "sticker" ?

If it is the one that was on the phone, then its gone I guess x:
[Samsung Galaxy Nexus] sblantipodi:
it exist a nexus screen without banding at all?
[Samsung Galaxy Nexus] jeNova-:
Well at least I really dont see any :/

Maybe there is and its just so minimal that I dont see it.

I think its kind of funny tho, I was scared like **** after this thread but now I have a really fine screen :D

As mentioned the only thing I notice is that on low brightness the screen (especially the greys and whites) gets grainy and the whites get a little blueish, but thats not really that big of a deal for me and seems to be normal with amoled(?).
[Samsung Galaxy Nexus] untruestory:
I think most of the problems people perceive are in their heads. Just fired up my Nexus for the first time. No lines, no dots. The colors are off and there's a green tinge the left edge. This is the same screen the Epic had right? My Epic had a much brighter screen than my Evo but I'm afraid my Evo is brighter than my Nexus. I'm headed to Best Buy to compare my screen to their demo. That'll tell
[Samsung Galaxy Nexus] Alexander T.:
It is located under the battery.
[Samsung Galaxy Nexus] jeNova-:
Ah, thanks for that.

It's C1 so january 2012.
[Samsung Galaxy Nexus] alexmad33:
Hi all!

I have a blue pixel in my N1. I think that the pixel is barred because the death pixels are black.

Do you know how can I revive it?

Thank you and sorry for my english
[Samsung Galaxy Nexus] Alexander T.:
What's your production date?
[Samsung Galaxy Nexus] Emama:
I just got mine today from Play store,

no tint fade or retention

However, I saw Black dot in the black screen and a horizontal black line across the screen..

and I have the same "二" black icon like this picture around the same location..

http://i.imgur.com/K5RiD.jpg

I think I should get a exchange..

But, is the black dots appears almost in every phone since I see so many people having this problem...

Made in China C2 (02-2012)
[Samsung Galaxy Nexus] kms108:
wrong thread.
[Samsung Galaxy Nexus] remedy1978:
black Dots

Ill be getting my third replacement hopefully tomorrow or Friday. The first two have the black dots, one with a horizontal black line through the middle. Either Google got a bad batch or perhaps this is the norm.
[Samsung Galaxy Nexus] rmcsc:
Now I see something I hadn't seen on my screen. The screen looks like it has some sort of texture across the screen. Meh, I was gonna ask for a replacement anyway. This just adds to my reasons.
[Samsung Galaxy Nexus] mgymnop:
Black dots are normal. I had them on my Galaxy S II too. There are supposed to be some without but I don't believe that.
[Samsung Galaxy Nexus] Emama:
My vibrant does not

but my Nexus S has one..

I dont care about that since even it is in lowest brightness it is not obvious.

However under the lowest brightness in Galaxy Nexus I can see that already at night,

it is VERY obvious when I take picture at night...which is not acceptable..
[Samsung Galaxy Nexus] kolyan:
Received Nexus, dont know if this is a defect but whites are very grainy. Compared to my One S and Nexus is just horrible. Whites are white without any grain on One S w/ automatic brightness.
[Samsung Galaxy Nexus] coolmaster121:
Two phones orderes but they are are soo different

I ordered 2 phones form Play Store, and one has the purple screen issue the other one is fine.
[Samsung Galaxy Nexus] kolyan:
Mine only has pink issue at zero brightness but screen looks just horrible with automatic setting....due to grain, its the worst screen I have ever used on a smartphone.... including my tmo shadow
[Samsung Galaxy Nexus] sblantipodi:
what about banding issue? do you have lines on grey and white color?
[Samsung Galaxy Nexus] Emama:
The quality of HD amoled screen is really :(

Even it does not have black dot..the grainy white color is really disappointed.
[Samsung Galaxy Nexus] sblantipodi:
what do you mean for the grainy white color?
[Samsung Galaxy Nexus] brian515:
Production date was C2 so February.

But here's the kicker. I called Google yesterday and they kindly overnighted me a new one which I just got. The new one is less grainy and doesn't have the lines, but it does have a green tinge towards the left edge, a blue tint towards the top, and some retention when the brightness below 20% or so. But here's the good part. I took another picture of a perfectly black screen. This new one has the SAME EXACT dots in the SAME EXACT places.

Old: imgur DOT com SLASH K5RiD.jpg

New: imgur DOT com SLASH dekMi.jpg

Samsung? More like Sam-suck.

Maybe #3 will be better, otherwise iPhone here I come!

PS The production date on my second one is also Februrary
[Samsung Galaxy Nexus] Emama:
see the 1st post 0% white

---------- Post added at 05:31 PM ---------- Previous post was at 05:29 PM ----------

why dont u post the link directly? :rolleyes:

btw, I have one of those "二" mark too...

which is very obvious during the night time especially in the camera app
[Samsung Galaxy Nexus] kolyan:
thats exactly how my phone looks. the ony way to get rid of the grain is to use it around 100% brightness level. One S also has SAMOLED grain but its NO where near what i so on Nexus.
[Samsung Galaxy Nexus] jeNova-:
Well I understand that people here are angry and pissed.

And although I am really glad I got a good one I can understand that and I think its just bull**** what Samsung hast done here to this awesome phone.

BUT the screen is in no way the "worst screen ever" first of all most issues are just on low brightness, so on normal brightness the screen shoud be fine right?

Well it sucks anyways, but the screen itself is gorgeous. And yes that its grainy on low brightness sucks, but is it really that big of a deal? I mean who uses his phone on such a low brightness? I dont even do that in the dark.
[Samsung Galaxy Nexus] Emama:
I put in lowest brightness most of the time in my Nexus S,

so I guess it will matter
[Samsung Galaxy Nexus] alangrig:
Either do I
[Samsung Galaxy Nexus] kolyan:
I dont even touch Brightness, mine is on Auto and its grainy as hell......simply unusable. I will settle when I dont see any grain at around 20% and up. My One S SAMOLED gets grainy only at 0% brightness....move slider 1 click to the right and most if not all grain goes away....whites are pure white, and blacks are pure black.....and its not even a flagship device with qHD pentile screen. How hard is it to fix a damn problem thats been there since launch date, or is it gonna be just like Nexus One were Google screwed all customers with cheap ****ty AMOLED ?

What is it with QA these days ? Is it too much to ask for a functioning phone ?
[Samsung Galaxy Nexus] remedy1978:
I had a Nexus One with an AMOLED display. It was 10 times better than the one on my Galaxy Nexus. Again, I wonder if this is a bad batch that Google is currently selling.
[Samsung Galaxy Nexus] brian515:
I'm a new member so XDA won't let me.

I'm thinking maybe it's the same thing. I had a Nexus One too and after 2 years that phone has no burn in or image retention issues. Even the gradients look better. Apparently effective today Google isn't doing the RMAs for the Nexuses bought from the Play store and instead Samsung is. That's unfortunate since Google overnighted me a new Nexus no questions asked last time. With Samsung I now have to wait a day for some person to call me back to authorize the RMA.
[Samsung Galaxy Nexus] kolyan:
Nexus One was fine, but it had bad multi touch issue.

Rep at Google said they are overnighting me my replacement Nexus....I suppose this is pure BS?

---------- Post added at 05:23 AM ---------- Previous post was at 05:14 AM ----------

PS. screen also looks nasty on a black background. You can clearly see defects.
[Samsung Galaxy Nexus] mingkee:
After careful observing, mine has faint "banding" at extremely low brightness (lower than manual lowest) when using facebook app. Morerover, there is a pretty faint "ghost" when opening "Draw!". Notwithstanding that, these screen issues are not bad as the first post and they are acceptable.
[Samsung Galaxy Nexus] kms108:
this is normal.
[Samsung Galaxy Nexus] kolyan:
Spoke to Google about my promised exchange which was supposed to come in today and yet i dont even have a tracking number or any word that it was shipped out....

Rep said that perhaps they ran out of stock and now Samsung is handeling all claims, he also asked me if I would allow them to check my device before shipping it out to make sure there are no defects....i agreed to this.

UPDATE: just got my track. delivery tomorrow. fingers crossed
[Samsung Galaxy Nexus] brian515:
When did you call? I called Wednesday and got my second one on Thursday directly from Google. It had the same defects as the first one, so I called on Thursday and Google claimed that Samsung was handling all other claims. I called Samsung and now I'm waiting for a call back from someone before they'll even ship me another one. Needless to say I'd rather have Google handle it. They were much more efficient, plus they sent me a sticker!
[Samsung Galaxy Nexus] kolyan:
I called Thursday morning and I suppose my order was handled by google since I haven't received any calls from Sammy. but my phone was only overnighted next day....which is today, so i should be getting it tomorrow per Google email (track still doesnt work)

hoping for the winner cause i wanna use AOKP, i hate unrooted Vanilla
[Samsung Galaxy Nexus] Emama:
Just got my replacement,

at the beginning I was very happy since it does not have any purple tint in the setting,

There is still some small black dots in the black screen but no more huge one.

However..when I check it again It come with 1 dead green pixel and one tiny tiny dead pixel (or dust)..

I don't know what to do now...

If I call again and even if they send me new one, it may have purple tint again...

Update: I choose to keep the new one with that green dead pixel since I cannot see it in normal use at all

Time to stick the Screen protector and ROOT!
[Samsung Galaxy Nexus] ajgorr:
Hmm, first post confuses me. Could you please tell me if this is normal or not?

This is minimum backlight setting, those lines are starting to fade out at 50% or more backlight setting. I would appreciate if my phone would be exchanged on warranty, since I have probably broken the NFC Secure Element while flashing AOKP update without wiping Google Wallet internal app data.
[Samsung Galaxy Nexus] kms108:
by the looks of it I think it's acceptable, if you do return it, you might get one that could be bad.

also the NFC is in the battery.
[Samsung Galaxy Nexus] ajgorr:
Thanks for your quick response. Would you think I could get a replacement anyway?

Also; isn't it only the NFC 'anthenna' is in the battery, but rest (including the Secure Element) on the motherboard?
[Samsung Galaxy Nexus] kms108:
if you insist that you see purple and it's in warranty, they will just replace the screen, but not the whole phone unless it's within 7-14 return period.

to be honest it looks fine to me, just a slight tint of purple, but this could be just the photo, as a photo might not show the actual true colour variation.

---------- Post added at 02:38 PM ---------- Previous post was at 02:35 PM ----------

what makes you think you damage the NFC, do you have any cards like visa pay wave/rechargable bus tickets or something like that, and download some apps from the market to test it out.
[Samsung Galaxy Nexus] ajgorr:
I just made another test, bumped the backlight to 100% and then swiped the notification bar, so it bends over the white background. Lines are still visible, more than the photo shows:

---------- Post added at 02:38 PM ---------- Previous post was at 02:35 PM ----------

The NFC itself works well, tested with NFC TagInfo app, VISA paywass card and door entry card. Program detects cards, reads the data etc. When it comes to launching the Google Wallet app after ROM was updated to AOKP5, there is an information that 'Secure Element has stopped responding'. I tried restoring NAND backup to the version when the Wallet was working, still same error. Some people already had the same issue with the app after flashing update packages or other roms. Some guy said, that when the Wallet app is not 'wiped' internally before flashing another ROM, the NFC Secure Element chip that is responsible for authentication while using the phone as a credit card, it is programmed to shut down itself (preventing any security violations, like theft etc) into unrecoverable state. That doesn't make sense to me either, it should be fixable by complete wipe or something like that, but in my case even going into stock image and relocking the phone still makes the Google Wallet app unusable.
[Samsung Galaxy Nexus] kms108:
too me the colour looks ok, it really depends on how much you will considered as acceptable, as for the NFC, you can try to flash with a stock rom.
[Samsung Galaxy Nexus] Android_Monsters:
+1
[Samsung Galaxy Nexus] kms108:
the banding shows up more on the gnexus and note, it could be related to the HD super amoled screen, but it is on every amoled screen.
[Samsung Galaxy Nexus] Emama:
Damn..

I post earlier saying got a replacement having good color but only 1 green dead pixel..

I chose to keep it..

However, I check it today and see the green or red pixel near that is dead too..

Does one dead pixel spread along time?

I put the Screen protector on already and I need to call Google again..

This time they forward me to Samsung....

Jesus....

Update: Samsung asked me to send the phone back to them,

And they need 6 business day to evaluate the phone by their technique guys and they may REPAIR it

And the main thing is, when I ask WTH? They disconnect my call, WTH??
[Samsung Galaxy Nexus] kingnaldo28:
Interesting, i received mine with a pink band in the right side of the phone, looks like bleeding, replaced with Google and they send me other with the same problem i returned ans ask for refund, i don't wanna gnex anymore. this problems scared me for a $400+ phone.
[Samsung Galaxy Nexus] kms108:
what you have are bright /stuck pixels, not dead pixels as dead pixels are black in colour only.

Do not mention to samsung you have these unless you have over 5 on the screen, according to the international standard, the screen must have about 3-5or above for a exchange or samsung can just reject an replacement.

Just give some other excuse.
[Samsung Galaxy Nexus] Chad_Petree:
Mine doesn't have banding but the screen is yellow as hell, I mean everything that is white or grey as a VERY noticeable yellow tint, its super annoying is this problem because of amoled or because of pentile?

My best bought a nexus too and his screen is almost perfect, he has the yellow tint but it is A LOT LESS noticeable :(
[Samsung Galaxy Nexus] Emama:
I am sure one of the Green pixel is dead since it show as black in green screen.

However, Samsung sounds like they will charge if they Think it is normal.

And I am struggling if I keep this now since one pixel is okay in 720p screen

( as u said, I am not sure if they replace for free for only one dead pixel; and I am scare if the new one is worse....):sly:

The customer service in Google help me to deal with Samsung since Samsung just have a Repair option for me.
