[Samsung Galaxy Nexus] coltronathon:
Well I'm having a GREAT time with my Nexuses (Nexi?). I just ordered my 7th replacement.. I'm starting to lose count. The direct line to the Verizon warranty center is 866-406-5154 btw. Getting that first warranty was the hardest. I barely had to make an excuse to get them to approve all my subsequent ones. I even offered to send pictures in or give proof but they declined.

**side note**

It's unfortunate because my 3rd or 4th Nexus was pretty decent. It still wasn't as bright or white as my SGS fascinate or my friend's gnex but at least it wasn't blue or red tinted. I realized that by running with my phones in my ringke slim case it allows the sweat to seep in and damage the USB port. Now I switched back to my ugly cheapo "condom" case and haven't had an issue yet.

My advice is that if you get a screen you can live with, keep it. The next one I get that's decent I'm holding onto for dear life. Look at the bright side... in another 5 or 6 months Google will release FIVE nexuses for us to choose from and we can say bye bye to this piece.
[Samsung Galaxy Nexus] darkvice01:
You're right about that guys.. we can say good bye to Samsung.. maybe welcome HTC Motorola and Asus .. I hope Asus will have pure Android..
[Samsung Galaxy Nexus] Molitro:
I can't really make it clear if mine has what's considered a defect.

Front top to bottom, the colour gets from a colder to a warmer tone (on low brightness).

I also see image retention when i close the keyboard and have a dark grey background. It last for a few seconds, or if the background changes.

Neither are really annoying, but I'd like to know if an screen replacement is likely to remove these problems, or I'm probably going to end up the same, in which case I'd just wait until some burn in shows up to use the guaranty.
[Samsung Galaxy Nexus] Matt08642:
New problem I've noticed lately, not sure if it's a recent thing or if I just never noticed it before

My screen has a solid blue line going up the left side, and it's VERY noticeable on anything grey (hard to see in the pic, though it IS there) http://i.imgur.com/IRUWj.jpg

Seriously, did they even test these screens when they made them?
[Samsung Galaxy Nexus] Frosty666:
Does anyone else's have purple tint even at full brightness? Mine does, but other people keep saying it goes away when they bump up the brightness just a little bit.

[Samsung Galaxy Nexus] Matt08642:
If you have ANY purple tint at all, your screen's defective and you should exchange your phone
[Samsung Galaxy Nexus] nickcuban:
Well samsung is standing strong that the 14 day return is from the original purchase date, not from each phone receive date. So google worked it to where i can return the phone and order a new one. I told them I'll return it, but not buy another one if samsung cant stand behind their product. I guess lesson learned and all it cost me was a trident case... Hopefully. I should get my return label tomorrow morning.
[Samsung Galaxy Nexus] Alexander T.:
Rest assure, all the GNex screens have these two defects! I had an opportunity to check about 15 (I'm not exaggerating) handsets, and ABSOLUTELY all of them had problems with color uniformity across the screen going from warmer to a cooler tint either from top to bottom, bottom to top, left to right, right to left or by diagonal. So, I picked up one that had minimal color change from top to bottom, when keeping in portrait, but it is still quite annoying in landscape. The good thing is that mine doesn't have the purple grays even at the lowest brightness level. I had 4 replacements, and my first 2 handsets suffered from strong purple grays as well. The current one is relatively the best compared to what I got before, so I decided to keep it.

The image retention is also normal; it was present on all GNexes I had, including my current one.

Overall, I think Google made a big mistake choosing those crap amoled screens instead of nice IPS LCDs.

I really don't think its the status bar and such. Even on a full screen black image the screen does not appear to be completely off.

Its just BS, feeling more and more let down by the device, yet I still love it.

Screen issues (banding on low brightness, not pure black)

Camera issues (flash makes everything yellow)

Music app issues (drop down notification and click pause = music icon disappears from bar, stuttering when screen off)

Sleep of death (occurs randomly and loose 10% battery after battery pull)

Different builds (Samsung, Google)
[Samsung Galaxy Nexus] chjade84:
The reason I wonder is that just like a edge-lit LCD backlight provides light throughout the whole screen, the white light from the navigation and status bar could illuminate the whole screen by reflecting inside the glass adding some light to an otherwise black background. I just can't think of a way to test it.

I created a black 720p video clip from a black image since that does away with the status bar and navigation but the blacks in video are noticeably brighter than "off".

The only other thing I could think of was rebooting the phone but the black background with the white Google logo would cause the same problem. FWIW the screen in between the Google logo and the boot animation IS 100% black - but I don't know if the screen switches off or just goes black for a moment.
[Samsung Galaxy Nexus] stretched:
Could it be backlight leaking in from internal led's? Are the screens sealed?
[Samsung Galaxy Nexus] chjade84:
The only internal LEDs are in the notification indicator. The rest is all AMOLED screen.
[Samsung Galaxy Nexus] NPuter:
Why is everyone complaining about color temperature? Can't it easily be changed if you are rooted/on a custom ROM?
[Samsung Galaxy Nexus] xDarKnighTx:
I've never heard of this... how do you know which build you have? and which one is better?
[Samsung Galaxy Nexus] dario3040:
All Amoled phones have this, RGB or not.
[Samsung Galaxy Nexus] bongadadu:
Sorry I meant, two software revisions. Samsung (yakjuxw) and Google (yakju)

It is believed that the yakju one gets updates faster as they are straight from Google, that is the one I have. If yours isnt then it can easily be flashed.

Loads of threads about it in the forums.
[Samsung Galaxy Nexus] kms108:
I think there is more version, mine is yakjuzs.
[Samsung Galaxy Nexus] EarlZ:
How about the bad (blocky) blacks on the G-Nexus has google/samsung provided feedback on it or is it a limit on the HD SAMOLED?
[Samsung Galaxy Nexus] aalmuhairi:
Thanks for this info, i bought GN today, lucky me i had a condition to try it if locked and if any defect would appear to accept it.

as soon as saw the screen at 20% brightness, i called it defect and refused it. so i went back online to check any info about it and found this thread.

Really google failed us here, i own G1, N1, NS, SGS2, and wanted GN, but this really stopped me from buying it.

i tested colors and blackness with s2, and s2 was richer color and better blackness.

now am not going to buy it.
[Samsung Galaxy Nexus] aalmuhairi:
OK guys. I got called from seller saying that he got me another GN piece to sell and it's new generation.

So I meet him and tested it to find it as promised. No screen gray lines or in clear white background as it shows in this thread.

So I end up buying it
[Samsung Galaxy Nexus] :
Is there actually a version two floating around without screen problems?
[Samsung Galaxy Nexus] Silent8Strike:
Has anyone actually compared a SGSII with the Nexus according to true black? In a dark room I can barely tell the screen on the SII is on, the nexus however is much lighter, almost like a LCD. If the pixels on the Nexus actually turn off and put out true black, why does this happen?
[Samsung Galaxy Nexus] aalin13:
Hi all,

I also notice some screen issues with my Gnex GSM model where the top of the screen shows a slight green tint.

Here's the screen at 0% brightness with a pure white background (google.com in browser)

http://www.flickr.com/photos/73445319@N06/6627174839/in/photostream

Here's the screen at 25% brightness with a pure white background (google.com in browser)

http://www.flickr.com/photos/73445319@N06/6627179997/in/photostream

As can be seen in these photos, it is visible only by staring hard at it at 25% brightness, but it is quite apparent at 0% brightness. I think there's also a dark streak near the left of the screen (in portrait orientation as shown in photo). Any comments? I'm torn on whether I should try and get it replaced, as I bought mine through Telstra in Australia and they will have to send it back to Samsung for a technician to make the call on whether it is faulty. I'm worried that if I'm not present at the Samsung's inspection, it will be hard to describe clearly the issue.

Cheers!
[Samsung Galaxy Nexus] Joshaldo:
Hey mate I have the exact same streak as you when I put my phone in portrait mode. I also bought mine from Telstra. Are you going to take yours back? This seems to be a fairly common problem, not sure if it is worth it.
[Samsung Galaxy Nexus] chjade84:
I don't really notice this in day-to-day use on mine. Compared to an iPhone and an HTC EVO my blacks are REALLY black. The bezel is almost indistinguishable even in a dark room with just the TV on.

For instance, the grey clouds on the Nexus's "Microbes" live wallpaper are the same shade of grey as the other LCD's "blacks".

However, if I get in a room with total darkness I can make out the black screen like people are saying. My theory is still that the navigation icons and status bar put out enough light that reflects inside the screen making the whole thing light up. There is a post I made back a bit of the individual pixels on and off and I don't see them on at all.

I am intrigued about this "gen 2" Nexus aalmuhairi is talking about....
[Samsung Galaxy Nexus] k_myk:
I'm not here to complain, I love this device and take it's screen with all it's advantages and disadvantages:) But I have to say that in a dark room, let's say at night, when SGN is displaying a night clock it is easily distinguishable from rest of the room. You can clearly see whole screen. That's unfortunate, because it doesn't look as awesome as it could:p but that is not something I would be paranoid about:)
[Samsung Galaxy Nexus] Molitro:
About the purple... I don't have any on normal use... but! if I bring down the notification bar, depending on what is behind the """"glass"""" it can become very purple.

Or to be more specific, the grey of the holo interface is what becomes purple the most.

I've been thinking this is expected behaviour, but let's ask just in case xD
[Samsung Galaxy Nexus] Alexander T.:
Mine is free of any purple on any brightness level.

There shouldn't be any purple at all, cuz otherwise you'll most likely have purplish grays/blacks in video and images with dark areas, especially when viewing in a switch-off-lights environment.
[Samsung Galaxy Nexus] ph0b0z:
I had it, i returned it. I think it's just harder to see at higher brightness, since there are less of "the greys" displayed. But i could even see it in the Brightness-Settings on the upper end of the screen.

Best way to see it was the Grey Saturation Test in the "Display Tester" app from the market.
[Samsung Galaxy Nexus] Alexander T.:
That's because even at highest brightness the viewed image may contain rather dark areas, which will still be visible as purple! It depends on the pixel's brightness level, in fact.

I've gone thru 4 replacements, 'till I got one that looks more or less perfect as compared to my old but ideal SGS screen.
[Samsung Galaxy Nexus] Frosty666:
I sent my phone to Samsung, they kept it for two months, did a data wipe and sent it back to me.

[Samsung Galaxy Nexus] Molitro:
I mean it just gets purple when is under the darkening effect of the dropped down notification curtain.

There is no purple otherwise at any brightness level.

But when I pull it down grey things do get purple. The thing is I don't know if that is considered a problem.

That really does the opposite of reassuring me. It really sucks that they're all like that.
[Samsung Galaxy Nexus] darkvice01:
Have you guys notice any galaxy nexus purchase in Korean's complained about the galaxy nexus Amoled issue?hmmmm
[Samsung Galaxy Nexus] a5pe4:
What did anyone who had splotches that show up on a black screen end up doing?
[Samsung Galaxy Nexus] Nickel Dime Bay:
I read the ones made in Korea do not have a lot of the issues that the China ones have
[Samsung Galaxy Nexus] darkvice01:
Ha.. just what I suspected. So now better to buy online website who's selling in Korea. That better chance than buying anywhere else.
[Samsung Galaxy Nexus] ph0b0z:
That's my second Nexus (Germany).. which i also will return again. :(
[Samsung Galaxy Nexus] Matt08642:
God I am so pissed at how shoddy so many of these phones are.
[Samsung Galaxy Nexus] darkvice01:
What I suggest return them both. Try to find galaxy nexus that came from Korea they have less issue compared to other countries.. I'm in Philippines and so far I ask Samsung to replace the LCD and I have the same quality of LCD. Only problem in my LCD is that black dint that can only be seen in dark room or dark places. I ask Samsung to put back the original lcd and I'll just take the replacement LCD before warranty ends. Reason is because this LCD don't last long and eventually quality of the LCD will deteriorate..
[Samsung Galaxy Nexus] sblantipodi:
where did you get the test image?
[Samsung Galaxy Nexus] Alexander T.:
Display Tester
[Samsung Galaxy Nexus] xm0nkey:
I've had 4 Nexus' so far, 2 Korean and 2 Chinese. The one with the best screen was made in China, but the radio/antenna is faulty and can't hold a 4G signal. The other 3 suffer from purple of some sort. The last one I got (LNR from Verizon) is from Korea and the purple isn't terrible but it's still there, althought not nearly as bad as the first 2 replacements I got. The newest one also doesn't suffer from the terrible blue-tint that you get on white backgrounds when viewing off-center. My one from China has a much better white balance and I think the Pentile isn't as noticeable when held close, but the black levels in some grays did seem to be elevated (sort of like improper gamma level) compared to the LNR I just got.

I'm torn on what to do. Might try to get another LNR from Verizon, keep this new one and just live with it, or possibly send my good screen into Samsung and have them repair the radio problem.
[Samsung Galaxy Nexus] darkvice01:
Well if radio problem then ask for replacement for the mother board..or yet another unit.. for the screen if you think you can live with it then stick to it but inform Samsung that you have defective LCD so that before your warranty expire ask them to replace it.. just tell the you will observe what will be the consequence if you use or stick with the defective LCD... that's what I told to Samsung and they told me if I'm ready for replacement I'll just have to go to there center and they will replace it.
[Samsung Galaxy Nexus] zaneburton:
When Samsung did an advanced replacement on your device, how long did it take before the hold came off on your credit card? Were you able to do multiple advanced replacements at the same time?
[Samsung Galaxy Nexus] zaneburton:
I'm actually on the phone with Samsung right now, and one of their representatives said that the purple hue/image retention was a known issue with phones manufactured in China, and that they were working to make sure that no more phones with the issue were shipped. Maybe my fourth phone will be the charm! The phones manufactured in Korea apparently have no issues at all...
[Samsung Galaxy Nexus] xm0nkey:
One of my Korean-made replacements had the same purple image problems as my China one.

I have to think the screens are all made in the same factory?
[Samsung Galaxy Nexus] zaneburton:
Oh...oh...oh no. How many did it take?
[Samsung Galaxy Nexus] xm0nkey:
First one was China. Good screen, faulty radio. The next was from Korea (brand new from Amazon), bad screen. Next was from China (brand new from Amazon), bad screen. These two were almost identical in screen quality, although the build quality of the Korean one was slightly better.

Last one I got is a LNR from Verizon from Korea and it's got an alright screen. Purple tint really isn't there, but it's got some noticeable lighter bands running vertically down the screen that my others didn't and the white point is not as accurate as my first one. I may just keep it, not sure. At least the horrendous off-center blue tint isn't as bad as the first 2 replacements.
[Samsung Galaxy Nexus] zaneburton:
When your Galaxy Nexus replacements are shipped out to you, does a four hundred dollar hold stay on your credit card until they receive the device? There was a four hundred dollar hold on my card initially, and I was curious
[Samsung Galaxy Nexus] xm0nkey:
I got mine through Amazon or Verizon and there were no holds or anything. I just had to ship back one of the phones within a certain time period.
[Samsung Galaxy Nexus] thetrailofdead:
Just received my 5th RMA. All from the Feb made in China batch. Each one had screen issues. I'm at the point where I'm just trying to pick the least defective one to keep. This last unit is probably the best, but has a very visible green tint at the very top, and the color isnt as good as my current one, but the ghosting is less significant. I'm seriously considering keeping this one, because Samsung's quality control is ridiculous and I cant seem to get them to send me a phone from a different batch.

That's funny, I could never get them to admit there was an issue. But each time I called, they didnt put up any fight to take my CC and send me a new replacement.

Umm, yeah, that's why they call you to get your CC so they can put a $399.99 hold on it. Didnt the CSR explain this to you or did you just blindly give your CC to someone over the phone?
[Samsung Galaxy Nexus] Formhault:
I just got my phone three days ago - it was bought on 26th of January, from a Vodafone store.

It went into warranty service only once (in March). Problem was the earpiece was making bad noises during calls. They didn't replace anything else but the earpiece.

Anyway, my screen has a purple tint to the upper left corner of the screen. Compared to that, the lower right corner is somewhat blue`ish. All this is visible only when reading articles (black text on white background). It's REALLY noticeable, especially when reading articles (~40 are saved in my Opera Mini, just so you can get an idea of the pain I'm experiencing, haha).

Besides, the gray from Settings, for example, is PURPLE when the screen's brightness is at lowest :( .
[Samsung Galaxy Nexus] RichAP:
What number are you calling for Samsung advanced support in US?
[Samsung Galaxy Nexus] ph0b0z:
Maan.. i start to hate this.. why can't the phone just work as it's supposed to be? :(

I had a small odyssey with the Xperia S this weekend.. my only alternative in this pricerange. It was actually really nice, great resolution, nice colours (well, the blacks were at least okay..), veeeeery good gps, a little faster.. and i like the matte-black colour and the monolithic design and i even think the sony-skin is okay.

but i hated the lower bottom and the really annoying buttons.. so i couldn't really fall in love with it. :/

The biggest problem with this is: most people won't even notice the purple tint. Or they will think you're crazy if you tell them that this is a problem. Why did nokia adress this with the lumia 900? why did sony react to the yellow-tint problems with the xperia s? why doesn't samsung admit anything?

And well, i don't really know how many galaxy nexus' are sold, maybe not enough in the "mainstream".

I'm really sad, since i want to own and use the galaxy nexus even if it's slower and has a worse camera than some of it's competitors and un-expandable memory.. but right now it seems to me that almost every device has this problem.

But i'll try a third one in the next weeks, seems that the stocks of most of the german shops are empty, i hope that's a good sign.
[Samsung Galaxy Nexus] Formhault:
Once you see it, you can't unsee it :) . My screen displays grays as purple only when the brightness is set at lowest or a close point (say, 10% or so). If I raise it to 20%, it is not purple anymore.

Anyway... let's just hope Samsung fixes their AMOLED screens in the future :) .
[Samsung Galaxy Nexus] ph0b0z:
Are you 100% certain of that? If not, maybe you should stop reading because maybe you can't unsee it! ;)

I had two devices here, they had both absolutely the same problems, it's only much more perceptable at very low brightness (since more of the affected grey-values are visible i think) but i could see this at 50% or 100% brightness anyways - not only on test screens, also on videos and photos with dark and shady areas (prometheus trailer for example.. ;)). (I posted some pictures of the 2nd device a few pages back)

So.. it's not actually PURPLE (as when you are in the display settings on 0% brightness).. but the exact color-values that you see there are used in any brightness-setting - at least that's my understanding of how this works. :o
[Samsung Galaxy Nexus] ph0b0z:
I just meant reading my post.. thanks for the nice post!

Is burn-in really covered by the guarantee in the us? i'm interested in that since it's another factor why i'm "afraid" of using it too much.. black button-bar.. whoo :(

and i don't think we have the lte-version in germany.. and i use a "contract" were i got restricted to 64kbps after 100mb of traffic.. since i mostly have wifi available and it's cheap. ;)
[Samsung Galaxy Nexus] Formhault:
Oh, so you're from Germany. LTE is currently available only in the US, so your phone is most likely a GSM. Oh well...

In any case, the burn-in is supported by warranty, or so it should. I mean, if you experience it, it's because of the defective nature of the screen, not your fault. If you spill water on it, for example, the app drawer button doesn't get imprinted into the screen :) ... but it gets stained / stops working. So I'd say a display with burn-ins is eligible for warranty ;) .

Dang warranty retards at the stores... They try ANYTHING just to avoid you placing your phone into service -.- but they end up looking retarded, and losing, anyway.
[Samsung Galaxy Nexus] Formhault:
Galaxy Nexus vs. Galaxy S3

I saw the Galaxy S3 many times until now. But today, I went to this store where the S3 (among a few other phones) has just been brought to life, so-to-say (until now, only mocks were displayed). So those phones have been used only for 3-4 days.

I wanted to compare my Galaxy Nexus's Super AMOLED HD display with PenTile to the Galaxy S3's Super AMOLED HD display with PenTile :) . I set both displays to maximum brightness, and I started Screen Test. Every color was brighter on my Galaxy Nexus, while the colors of the Galaxy S3 were more feint.

The Galaxy S3 doesn't display grays as purple when you lower the brightness (but you can say the same about the S2 or the Note), and that's the only advantage I'd say it has over the Galaxy Nexus. Aside from that... it just sucks, seriously. The Galaxy S2 and Galaxy Note were there, too, and the displays were exactly the same as the Galaxy S3's :) . Yes, although the S2 has a Super AMOLED+, it was the same as the Note and S3.

Note : the Note, S2 and S3 screen modes were set to Standard.

-----

Conclusion? Galaxy Nexus ftw :) .
