Also, when viewing the screenshots on a computer (Dell 2208WFP), they do not look the same as they do on the phone. The dimmed desk clock has a black background with white numbers and the Youtube ones do not have the blotches.
Anyway, I love this phone, but I'd really like to know if I have a defective one or not. What do you guys think? Should I try and get it replaced? I live in Brazil, so it's not quite simple to find someone else with this phone to compare. But I will try to have it replaced if this one is indeed defective.
Thank you very much for all the help you've provided through these forums. I hope I was able to provide some too. Merry Christmas!

PS: Really, really sorry if this is considered spamming. It was supposed to be one post, but I guess only one link is allowed per post.

Also, the aliasing happens a lot when using the camera. Not only on black, but whenever there's not a lot of ambient light. Seeing through the screen gives a completely different and sometimes undistinguishable image.

I don't think you have a defective unit. This is just how the phone's display is. Video playback is horrible unless the video is high bitrate and/or 1080p. I'm still debating returning it, since I don't think it is something that will get fixed.

What I don't understand is why this isn't being reported more widely? And why people who have a similar display on other phones say they don't see it. E.g. someone with a fascinate doesn't see it. So is this a software/display mapping problem or is it just crappy hardware? Is there any hope of it being fixed? If not, I may return it.

Thumbs down Bad news people

I finally found a thread on XDA of Galaxy Note owners. They have the SAME issues, and as far as I can tell it's a hardware issue. There are a few reports of users without the problem, but those seem to be a rarity (and may just be people not watching in full darkness).

There is some speculation about it being something Samsung is doing and adding too much gamma or something.

Full thread is here:

[Q] Video on Note - xda-developers

Looks like this is par for Samsung's displays now. If this is not correctable, I'm returning my Nexus and waiting for a device I truly want. I have decided not to settle for a Rezound or Razr. Although I may get the Rezound if it gets S-OFF and CM9.

VERY disappointed in this Samsung. What a joke.

What makes me wonder if I got a defective unit is the fact that a lot of people do not seem to have the issues I'm having with my GN. And I don't need to be in a dark room to see it, and bet the effects would be visible to anyone who looked at the device I have.

I think the issue is ubiquitous, but some people can't see it or it doesn't bother them. For me, I need a phone that I can watch videos on without seeing the "black crush" effect.

I just got a chance to test this in a real world situation. I had a 4 hr plane ride so I downloaded a 720p movie. I watched the whole thing in dim/almost no lighting. I saw NO issues. I see the problems with the clip the op posted but didnt with the video I watched. I think it could be just a few badly encoded videos that have issues with the GNex screen

Unfortunately I think most content on hulu, Netflix, YouTube and TV shows/movies on Usenet/p2p are not of sufficient quality to hide the color banding. Higher bit rate/higher resolution videos make it less noticeable but only self-encoded videos with better encoding than what people would torrent or something will better hide it. Boosting the contrast helps a little bit with some cases of the color banding but not all the oddities I saw on my nexus screen. For ocd people like e, you are probably better off with an IPS or LCD based screen, though they have their own trade offs. :-)

I just exchanged my phone for radio reasons (seems to be better now on the replacement model btw). I watched this clip with my other phone in a darkened room and saw the blue posterization at both low and high screen brightnesses. It was really bad and I noticed it before it was pointed out to me on the forums (I watch movies in a very dimly lit to unlit room at times as well when others are trying to sleep). The replacement phone has some posterization in the shadows under the same ambient lighting conditions, but it is neutral gray and very, very subtle - nothing surprising for the source material quality or objectionable. I would say that the only way one is going to see this is with a display with the black level capability of an OLED display. You probably wouldn't see it in an LCD display because the black levels cannot compete with OLED. I'll reiterate: I'm picky and I did not find the level of posterization distracting, nor was it royal blue/purple-ish as it was that my first phone exhibited.

Further, I saw the blue posterization in the display when taking pictures in very low light as well, as some others have reported. I just tested this camera under low light (read: near blackout conditions, but similar to what I had previously seen) and there is no blue posterization.

My experience here is just one data point, but it does suggest that there may have been a bad batch of screen controllers in early production runs. I have no idea when the part that I have came off the line.

I had ZERO of this on my first GNex, but I do have it on my replacement. There is at least one out there that doesn't have it. I watched the video on the first page of this thread on both phones. This one has it, first one didn't.

FYI, for anyone still bugged by this on the nexus, someone over on xda found a way to improve things

[Q] Video on Note - Page 22 - xda-developers

I don't claim to know the technical details behind it, but maybe it's possible to do something similar on the nexus!

All he's doing is changing the minimum black levels to be much lighter. Basically defeating the great, rich, "true black" produced by the AMOLED screen, and instead making the black levels actually produce some light/color.

So, it's not really a "fix" - more like a workaround.

Probably makes some people happy - I'd rather have the darker blacks and accept the compression artifacts for the movies that are over-compressed.

Yep, always good to have options. If you're interested in the details of what he did, he adjusted the gamma correction levels to be brighter. Gamma modifies dark regions to make them brighter or darker.

Wikipedia has a good example of what gamma correction does (not embedded because it's a big image):

FWIW, I've seen these artifacts at both spectrums...

1. My friend's gn does not have any artifacts with the video you posted, even in the darkest room

2. My first gn had HORRIBLE blue box-ing in the video, and was visible at dimmer levels. However, I realized that my gnex had completely washed out colors and got it exchanged.

3. The one I have now has some blue-boxing in your video, but only when it's pitch-black. It's also visible in the camera at low-light levels. It doesn't really bother me because I haven't seen it on any other video.

If it's still bugging you, there are ones out there that don't exhibit any artifacts. You could probably bug CSRs about it for an exchange.

Was just at VZW store and checked out their display model. What I noticed right away was their display was brighter. The whites were whiter than on my phone. The rep came over and I showed him and he said that maybe I had defective device.
I then loaded up the video from first post.
My phone with the lil bit darker display showed less noise on the video. Quite a bit less. Their display,being brighter, was horrible with that video. The rep was then puzzled and didn't know what to say.
Also on the recent call log screen, cleared so it is all black, the display had banding up the wazooo. Mine, being a lil darker was much better. All of this was done with the same brightness settings.
So my question is, would u rather a phone with not so bright whites and better with videos and banding or the whiter whites?

To quote Darth Vader, "it is too late for me" (son).

But yes, ultimately, the person needs to answer that question for their own needs/wants out of a display. For me, it was enough of a problem that I went with a phone with an LCD display which I knew would more suit me.

I have just read the entire thread.

In my opinion if you are really unhappy with a device then just return it and buy a different device.

Although you will probably find a "fault" with a different device.

When are people going to realise that nothing is "perfect", if you go for an lcd you'll likely find backlight bleed, washed out blacks etc.

The internet is full of threads of people complaining about every device out there, what's worse is some people who see no issue in normal viewing then set up un natural scenarios to find "faults"

Now before anyone flames me or accuses me of trolling, I'm not. If something is an "issue" then I'd exchange it, if the next device suffers from the same "issue" then it's "normal". Some people do like ten exchanges and think they are just unlucky and all the units are faulty. That is NOT the case.

Life is far too short, rather than complain and be unhappy just try another device.

Although I believe that some people will find something to moan about with any device, honestly if you are looking for a "perfect" device you will NEVER find one, no screen technology is perfect.

For me personally I can't stand backlight bleed, and washed out blacks, so lcd is NOT an option I want to take.

I'd rather live with the limitations of oled.

I thought it was my imagination and was seeing it on certain videos where scenes were very dark. But was nowhere near as bad as this video that the OP posted/ I think what you saying about codec that some have mentioned makes sense.

Also I tried the same videos on my fascinate which has this same type screen right? and it looks perfectly fine.

The post ahead is contains lots of colorful pictures and really pushes the issue in your face, if you dont have such problems on your screen after doing the exact steps/test/scenario then by all means be happy and dont be a thread griever.
*** WARNING LONG POST AHEAD****


If you guys are using the web browser or youtube application or any other streaming app then you will never see this problem since the deepest black those applications can go is only and RGB value of 16 instead of a full 0, the issue happens between RGB 8 to 1.

To prove my point watch this video using your web browser or the built in youtube applications and use keepvid.com to download the said video and play it back on your Galaxy Nexus/Note and see the difference in black levels and blocks/banding.. So that we can have a very objective viewing experience it recommended you do this test in a dark room or in a place with minimal reflections.

Another sample to download:
Batman-Rises.rar

It contains the new batman (2012) trailer, both clips are identical but one is using a full color range of 0-255 while the other one is limited to 16-255. Take note this issue only happens with both Galaxy Nexus and Galaxy Note, playing this video on any other superamoled device will not show any issues.


Sample images on how it looks like on the Galaxy Note, 99% this is how it would look like on the Nexus as well.. to a certain extent






Here is a sample clip of ironman2, Idk if i've posted his one here before

How it looks like on the Galaxy Note/Nexus then follow by how it looks like on ther non HD SAMOLED device like the Galaxy S2.













Do you want to contribute something to the discussion aside from saying I dont have such issues then by all means post a picture showing the test clips with the same scenario, your contribution can help those who have this issue and forward it to Samsung. In my case they've replied to me that they see the issue but with only a single report from my country the ticket is just pending away.

So comparing these two, I see it in both, but it's definitely more profound in teh 0-255 video. Even on youtube with this clip I can see the "purple->gray->black" halo effect around :30 into the clip in the sky in the upper left and right.

I've kind of given up on watching video on this phone at night which is kind of a shame. I'll have to use my trusty old dinc for that I guess or save up for a tablet.

How did you report this to Samsung? I'd like to do so anyway, on the off chance they decide to actually address it.

I showed them a picture of it playing back on a Galaxy S2, Galaxy Note(mine) and on a friends Galaxy Note that didnt have such a horrible clipping+banding as mine, the person said that they can understand the issue and forwarded it to the 'HQ' but theres been no development anymore since Im actually the only one who reported in my country.

From there I demanded to get a refund and Im hoping it gets approved. They did refund my Galaxy S2 w/o a fuss.

Fantastic post EarlZ! Thanks for doing the hard work of finding a detailed reproducible test case for Samsung to work with. I have a suspicion that they were already aware of the strengths and flaws in the panels, and you might not even be the only one to have reported it to them (denial being a common response from many manufacturers), but you've highlighted the problem in a concrete and irrefutable manner.

FWIW, we're pretty good about handling griefers around here, but all are invited to press the button to let us know about any hostile or disruptive messages.

@BlueBiker

Thanks, I've already reported this to my local samsung office and they have agreed to give me a refund since they are not able to fix the issue with a screen replacement and the issue varies from screen to screen. I still had 1 pending screen replacement but they advised me to cancel it and they want to get my phone as is so they can examine it, Hopefully all of their words are true.

Did you purchase directly from samsung? If not they will still refund? How does that effect your contract with verizon?


I just realized something, I had exchange my Nexus 4 times for different reasons each time, so when I went to check batman video and even the one above the reelsteel clip one, I saw a huge improvement, maybe a fleck here and there, but nothing I would never really notice unless I was purposely looking at it. It was a huge difference compared to my first device. It is like night and day.

The thing is my screen is not perfect, I have this horrible vertical band right in middle of screen, not as noticeable at 50% brightness or higher but still annoying and contemplating getting exchange again but don't want to go through hassle.

What does that mean? I think samsung has horrendous quality control, and just this never came up in their tests. Not sure how or what causing it and if it will ever get fixed.

So I think you should get money back no way to know if they be able to fix it. Same for others unless you keep exchanging, but maybe have 1 in 10 chance of getting a good one.

I actually own a Gnote and not a Gnexus but my friend who has one has the very same results as I do.

My phone was purchased in a samsung retailer so I dont need to trouble with any contracts.

Its been known that every screen differs in the playback results, its all lottery

yeah I am still contemplating if I should exchange this to fix the vertical band because it really annoying me, but then my luck I get either purple tint on grays or this problem will start up again.

It really ridiculous so many problems with display on a $700 phone

I don't blame you, only reason I am sticking with nexus at this moment, is because of pure ICS and dev support.

I am so tempted to go rezound if they just had ICS officially.

It didn't look very likely the Rezound was going to get AOSP ICS support other than hacks that would work poorly (e.g. performance might suck), so I decided I would live with the video stuff since the rest of the phone was to my liking.

BTW, someone opened a google bug report on this, so I would suggest starring and/or writing in your experience. Probably a long shot that it'll help but starring it will take 5 seconds, so...

Just curious, do you know of any reason Rezound might perform poorly with any particular ICS variant? Reason I ask is that its Snapdragon S3 is still reasonably close to leading edge while also being thoroughly mainstream, so I'd be surprised if there were any major hiccups in porting ICS to it.

Good. It's one thing to complain about problems, but it's another to put it in black & white on the developer's plate to fix.

Noticed this issue for the first time on my second GNex and it is extremely annoying. Is it a software issue that can be fixed?

Default Pics taken of the dr who video

I took a few pictures at various exposure levels of this sample video which demonstrates the "halo"/"splotchiness"/color-banding effect during video playback. The pictures of this video are from the very beginning of this video:

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

Here are the pictures demonstrating what I see on my phone when I watch videos (more noticeable in a completely dark room, but sometimes even visible in low-to-medium light).

This was taken with dice player @ 75% brightness.

Hardware issue as of now as a replacement with a non defective screen can fix the issue.

I'm now watching the "test video" in the stock player on two Galaxy Nexuses. One is from the UK and has a Modaco ROM, the other one is brand new from Australia. The first one has the problem and the second one doesn't, even if I make it brighter than the first one.

Can you post a side by side picture of the two please? Also, since this is a ROM, it sounds like it is not fixable without a hardware replacement or if Samsung can swap the ROM to the newer/fixed one.

If you can post some pictures of the two side by side playing back various videos, I would love to see how much it is improved. Especially the Iron Man 2 trailer video here:

IM2_Sample3.mkv

And of course the video in the beginning of this thread (@ 7-8 seconds in):

http://dl.dropbox.com/u/28717002/test.m4v

And the Dr. Who clip (first 1-2 seconds):

Well that's not the answer I was hoping for but I guess it makes sense as the first GNex I had didn't have the issue...guess it's off to Verizon later to see if they can get me another refurb that doesn't have this issue.

Have to say this is down to bad videos. I tried promethious trailer on youtube and the blacks arent perfect although none of the effects this thread is suggesting.

Expendables HD looks perfect and the blacks are almost black with none of the problems suggested in this thread.

Dark knight rises trailer is a little greyer on the blacks but no artifacts.

What I have noticed is all the videos with issues are the apple trailers, so i'm blaming apple, as all the none apple trailers I watch have perfect black backgrounds!

This is UK GNex on 4.0.2 stock on orange. Normal lighting, 50% brightness.

Yes, this is "purely" a video quality issue in some respect, because uncompressed or sufficiently high quality videos will not display the artifacts. But it also is a hardware/software issue too, b/c this type of screen is known to show these artifacts, but maybe a software fix exists... I'm not really sure. It's not only a video quality issue, because the artifacts cannot be seen on different screen types and it purportedly varies from GNex to GNex in severity.

I just watched the iron man 2 sample... didn't watch that one before... and notice a poor banded gradient in the horizon behind iron man, and some artifacts in the smoke early on in the scene. Also, this was on full brightness in a 100% dark closet with MX player (screen set to 100% brightness both in MX and in settings, turning brightness down in MX and the artifacts disappear for the most part). The video in general is very bright, I notice details that are not visible at all when watching it on my laptop --- however, even on my laptop, I can see some banding in the horizon, but it is much fainter. So makes me think there is something going on with contrast/gamma too... If everything that was black on my laptop was black on the GNex, I wouldn't have noticed anything at all. And turning brightness on MX down mostly makes the artifacts disappear, but the video is then a bit too dark.

I am starting to think that this can be fixed with software for the most part...

***New finding: On my laptop, I can make the artifacts appear if I open it in VLC and turn the contrast down just a bit!. See screenshot from VLC on laptop with contrast & brightness ticked down, and gamma & saturation ticked up, just a hair each.

What would be really nice is to have screen calibration options in the stock settings menu. And/or video player that can save profiles for screen settings --- such as contrast, brightness, saturation, and gamma.

The bottom image looks brighter on the photo, but IRL I've tried to set the overall brightness the same on both phones. Which means 100% on the brand new AU phone and 28% on the Modaco UK phone. Modaco brightness is significantly more agressive, which is the way I want it.

With Screen Adjuster I can make this video on my UK phone look exactly the same as on the AU one. I wish DICE player had this capability, but I only watch videos on the tablet anyway.

However, if I reduce the contrast on the UK GNex, its black (e.g. notification bar) becomes grayish, whereas the AU phone has true black.

It does look like a hardware (screen technology) issue which is masked by tweaking the software (contrast and brightness). But the UK phone seems to be able to decrease the contrast of videos without decreasing the contrast of other things.

This pisses me off. It really does. Verizon and Samsung are claiming there is nothing wrong. This clearly shows there is a hardware flaw which they fixed and are just trying to pawn off the shitty screen to people who they hope won't know any better.

With your permission, I will submit this image and thread link to the google bug report I filed. Seems more like this should be Samsung's problem and we need to all call them and bitch about this vocally and frequently.

The Modaco ROM brightness levels are significantly raised, the contrast might be tweaked as well. I used the stock video player for the photo, but the problem manifests with other players.

Permission granted. :-) But I don't think Google should care about a customised ROM. This is what I currently have on my UK GNex: http://android.modaco.com/topic/351478-14-feb-ir11-beta-2-imm30b-404-cdma-gsm-modaco-custom-rom-for-the-galaxy-nexus/

Seriously, play the test videos in VLC on your computer with these settings as shown in the attached photo. I can reproduce nearly every artifact I've now seen on all the videos...

Can someone out there play this back and see if you notice it? I think it's pretty hard to miss, but would like some others' feedback. Watch the black parts of the video (especially the guy's hair on the left) and you'll see some really annoying blueish/light-blue blockiness in the black areas. This same video played back on my dinc doesn't show this.

I'm also curious if people with a Rezound can check this? That will probably be my next option if I return the Nexus.

Thanks in advance.
I know it's late but I kept seeing these threads and thought I'd give it a shot. Not sure if I'm doing something wrong but I chrome-to-phone'd the link and it opened in my stock video player right away.

In the black parts in the beginning, I'm not sure if there is supposed to be detail there but the black on the left looks completely black including his hair. I saw some strange texture for a minute but I think it's because my phone was streaming the video.

I didn't see anything blue, or posterized. I'm not in a completely dark room but it is dim and my screen was at 100% brightness.

I've also watched videos on Netflix and the quality is always great.

Let me know if I did it wrong and I will re-test my device if so.
