I guess it's normal if the temporary ghosting/retention happens in just a couple of seconds. Hd samoled uses organic material, so it needs time switch off and on the RGBG diodes to produce the display.

I have this symptom on a brand new replacement phone. Very noticeable when switching to gray background, for instance when displaying the homescreen for a minute or two and switching to settings menu, i still could see the apps center/drawer icon was still there for about 2-5 seconds and then faded away.

After many reading about this, i guess it's normal if it happens for just a quick couple seconds. Just don't pump up your brightness too high and leave your screen on for long time.

I notice mine has this issue for about 2-5 seconds as well. In dark rooms, that time is significantly longer. I see some ghosting up to 10 seconds when using my phone right before bed. I will have to say, this is less annoying than my Droid Razr Maxx's black splotches. I find the black splotches on the Droid Razr Maxx to be more noticeable than a little afterglow on the Galaxy Nexus. I might still exchange my phone just because I had other issues.

i know samsung has been accused of copy catting apple iphone design, but one thing for sure they somehow missed to copy cat iphone display build quality. lol :D
[Samsung Galaxy Nexus] xpeter88:
This is exactly my situation. Do you think guys that this a software problem and can ce fixed somehow? It shows me this defect on low brightness only. When I am on 40± %, everything looks much better. It is also problem on white or grey background only so on the botom part of display is a tint of this colors a litle bit different.

it's hardware issues, but you can hide it with software using either trinity or franco kernels, or other kernel which has the tools to set colors and gamma settings. :)

i don't have purple tint right now at 0-10% brightness, but i got stripes/banding/textures on gray (heavy vertical and horizontal static stripes pattern), white (slight banding on the right), and red (annoying horizontal stripes) backgrounds.
[Samsung Galaxy Nexus] xpeter88:
Shall I kindly ask you for some pictures taken after this correction? U just bought my nexus and I am unhappy because of this problem :(

finally, better replacement screen!

quick update, after around 20 minutes long the time the technician took to replace my screen, finally i got much better screen today! :)

tests were done in 10%, 40%, and 100% level of brightness in a low ambient room lightning, except for the black splotches test is done in a very dark room displaying pure black (#000000) background in full screen mode. testing in mid and high ambient room lightning minimized all the defects.

results:

no purple tint. very slight purple thin on 10% brightness, but no purple tint upward.

no texture on white background.

very slight vertical banding at the right side of the screen on white background when brightness is set to 10% brightness and lower, but pumping the brightness up a bit makes the banding goes away.

no texture on gray background.

light vertical bandings on gray background on left-center-right of the screen, the banding is fading away as the brightness is up. no more vertical banding on 100% brightness.

very very very slight vertical banding on particular other colors in 10% brightness, but I'm afraid it's just me being paranoid. Haha :D

black splotches are still there but less sporadic and less in quantity. as popping up pure black background in full screen mode in a very dark room, the black splotches are populating half the screen making thin vertical line on the right edge of the screen, while other are spread sporadically at the rest of the corners (major) and edges (minor).

the white is solid now, while the gray is still not as solid as it should be due to the vertical bandings or the inhomogeneity. take a look at the loading of google play screenshot on the attachment and compare side by side it to your gnex and computer displays. :)

temporary image retention/ghosting/burn-in/burn-out or whatever it's so called still there but with a very minimum time to fade away and it also very hard to look for. while on the old screen, it took 3 to 10 seconds for the icons on home screen faded away when displaying the homescreen in a long time and did a quick switching to settings menu.

Gnex screen is still a level or two inferior compared to SGS3 though they both using the same HD Super AMOLED technology while only having differences in screen size and ppi. 5 from 7 of SGS3 displays I tested with were able to produce solid white and gray on 0% brightness.

Compared to the old screen, blue colors look pale/brighter, gray background on keyboard looks brighter though not pale enough, and the light gradient gray on the bottom of settings also looks pale/brighter.

too bad both samsung indonesia and the technician herself couldn't tell me where the replacement screen was made. it's not near perfect but i can tolerate it. at least with this screen replacement, the inhomogeneities of the screen is lesser than the old one. overall, i'm quite satisfied with the replacement screen. will get it replaced later near warranty expiration date. i'm sorry for being not able to photo the issues i have above since gnex is the only camera i have. :D

here's a full size screenshot of google play loading page to compare with.

I had other problem after using it for near two months, somehow the screen was producing lots of horizontal banding stripes on red background especially in low brightness.

But i did have textures on white background in low brightness, and gray background even in 100% brightness.

This one am using is much better displaying solid colors. The white is solid above 10%, while the gray is solid beyond 40% brightness.

What is normal burn in on these screens? I got mine in June and the screen already has a keyboard burnt in.
[Samsung Galaxy Nexus] chrone:
sorry couldn't help you out with that. i only used these gnexes for a short period of time, the longest one was near two months old and the screen got replaced with a new one.

but from the old screen, i noticed there's a temporary image ghosting while using keyboard for couples minutes and then switched to another app which has gray or white backgrounds. it took only just a couple seconds before it faded away though.

just curious, in what level of brightness do you use daily?

i use mine on auto level brightness almost all the time and sometimes back and forth in 10%-40% range. the new replacement screen has image ghosting too but it fades away super fast, it's hard to notice compared to last one. :)

Mine has purple tint with stock rom but fix it with franco, need a replace?
[Samsung Galaxy Nexus] darkvice01:
I'm back.. Samsung decided to replace my galaxy nexus. Just waiting for approval from the management. And about the new Motorola. They said that LCD is suffering with yellow colors.
[Samsung Galaxy Nexus] chrone:
if it doesn't bother you than don't. claim it whenever the warranty expiration date is near. :D

hope for the best. :)

yeah not all oled displays are made equal. gnex has this purple/blue tint, banding/stripe/texture/mura, and black splotches, while motorola has black splotches. the yellow/green colors on moto devices perhaps 'caused of oled can't produce true white especially in low luminance. on the new replacement screen of my gnex, the white is now more warm, tend to be more yellow/green compared my friend's gnex running on trinity which has cold white color.

i do hope they pre-calibrate the display before shipping. i bet almost all the defects can be minimized by calibrating the gamma and rgbg.
[Samsung Galaxy Nexus] Lorthirk:
However, with all these defects in my GNex screen, all I can say is: I'm DONE with AMOLED. SLCD for ever.

You're right on that one. Can't wait what padfone 2 will offer though
[Samsung Galaxy Nexus] untruestory:
My screen doesn't suffer from ghosting. It's actually burnt in. When I boot the phone you see the image of my keyboard. I use mine on auto during the day. At night I use it on the most dim setting.
[Samsung Galaxy Nexus] :
Screen banding example, is this worth returning the nexus for?

This is at minimum brightness, the banding is slightly less exaggerated in the picture than in reality. The banding mostly disappears from whites at 50% but not completely gone until 70%. Even at 100% I can still see the bands on browns and grey colours when watching videos.

Is this worth returning the device over or should I just accept it as normal?

Thanks
[Samsung Galaxy Nexus] chrone:
yikes, what is wrong with super samoled these days. :/ just claim your screen replacement.

all i can see on the picture above is that you're having vertical and horizontal banding or stripe or texture or whatever it's called. i got mine like that on white and gray background, the white had lesser banding while the gray still had it even at 100% brightness. so i swapped it and got better display but not perfect. now the white is acceptable above 10% brightness, and the gray is great at 40% and above. all colors now looks perfect at 50-100% brightness range.

if it's bother you than it's worth returning and asking better display. :)
[Samsung Galaxy Nexus] natzy85:
I noticed I have a blueish color were white is suppose to be in the upper display region. I noticed when I turn the phone to landscape to be able to write a sms. I tried display tester and run all the colors test and it seems fine. The display of the phone I had replaced last week. It is an original display.Should I be worried?
[Samsung Galaxy Nexus] chrone:
samsung hd samoled display technology could not produce true white in low brightness, sometimes they have texture/banding/stripe/yellowish/greenish/purplish/blueish and so on you name it. using display tester and run the dead pixel test, by default it runs on 50% brightness, and you should see solid colors produced on your display, try to lower the brightness by swiping to the left and set to 1%, 10%, 20%, 30%, 40% and see if the blue on white is still there or not.

if the blueish doesn't bother you at low brightness, then just enjoy the screen. otherwise claim your warranty. :)
[Samsung Galaxy Nexus] natzy85:
I also noticed that in low brightness with the Nexus I don't have to use Screen Filter app in order to watch the screen. On my last phone (SGS2) it was very bright and it bothered my eyes. So the pentile uesed on Nexus is more acceptable when reading right? Outside on full brightness from what I have seen is it the same as SGS2. It direct sunlight is not quite readable.
[Samsung Galaxy Nexus] chrone:
actually on what level of brightness do you use daily? 40% is the max my eyes can take in a room, while on outdoor it's the minimum. i use auto almost all of the time though.

by default, your vanilla ICS or JB is set either to 40% or auto brightness, and yes it's more readable that way. i often read news and articles from google current and they look great!
[Samsung Galaxy Nexus] natzy85:
I'm on stock 4.1.1 and always with auto brightness. Also SGS2 was on auto but a lot more disturbing to look at.
[Samsung Galaxy Nexus] chrone:
Oh i see. Try to crank up your brightness to half full from the power control widget (it's actually 40% from the settings > display > brightness) and see whether the blueish banding is still appear or not.

It may be that I am just paranoid and afraid that something wrong will happen with this display also. When I bought the phone from a guy when I got home I manage to see in low light that the upper part of the screen was faded away but it was to late to do anything. In about a month or so the display started to loose pixel until it went black. I switched the display and the battery a week ago. Everything seems ok but last night while reading in the dark room I noticed the blueish color were white should be. In normal light it is not visible. So now maybe you understand my concern. Am I just paranoid? :D
[Samsung Galaxy Nexus] chrone:
Oh yeah, you're that guy who bought a new screen from samsung back then. I don't remember having blue tint on white in dark room, but it's ok if you don't see it in daily use. It's just that the auto brightneas set to low in a dark room then the display had difficulties producing solid white.

To ease your mind, using auto brightness, i too have vertical banding on gray background in dark room.

Enjoy your screen for a while. You do still have screen warranty from samsung, don't you? When the blue diodes of the screen deteriorates in time, then claim your warranty.

Blueish tint is reported normal for OLED display, you could google about OLED display in wikipedia, some manufactures tend to give us big blue diode to prolong the life span of the screen since blue diode on the OLED tends to deteriorate much faster than red and green diodes, hence the blueish appears. I might be wrong about this, don't hesitate to correct me. I will update the source link once i get back on my PC. Cheers! :)

Hope this helps. :)

So what are the odds of getting a good one if you get it fixed? I do have extra parts coming for mine, maybe that one will be good.
[Samsung Galaxy Nexus] chrone:
Can't tell you exactly, it's just like a lucky draw for most of us here. You can minimize or even get rid mostball of the defect if you care to use custom rom or kernel with colors and gamma calibration. I happened to saw what a cyanogenmod 10 build sep 20 did to his device, it turned to near perfection on white and gray backgrounds, while on vanilla jelly bean rom hid screen has banding/stripe/texture.

Hey guys,

So what's the verdict? Should I get the Nexus or not ? I am getting a very good price for a brand new one here in India but it is an imported UK piece and without warranty. Since it is without warranty, am scared a little. Also, do these problems occur anytime during its lifetime ? or can I just check the piece in the store itself before purchase, and if I don't see any of the issues, should I get it ? Or are these problems going to occur anytime during the phone's life ?

Thanx a lot in advance for any info. Desperately waiting for a reply :)
[Samsung Galaxy Nexus] chrone:
again, the verdict to get good acceptable display on this current batch of Galaxy Nexus is like a lucky draw. Test your screen right at the store before purchasing and hope for the best. I got horizontal stripe banding on red background after using it near two months then got it replaced by Samsung Service Center.

If you happen to own defect screen, you can eliminate or make it hidden by using custom rom such as cyanogenmod. a friend of mine who happens to own stripe banding defect get his screen produce solid colors on cyanogenmod 10 nightly build.
[Samsung Galaxy Nexus] Kazekage Gaara:
Thanx for the input. Since it's a "lucky draw" :p I've dropped the idea of getting the Nexus altogether. Now am thinking of either getting the Xperia S or Atrix 2 which are close to my budget :)

Thanx for the input dude. Really appreciate it :)
[Samsung Galaxy Nexus] chrone:
don't get me wrong, despite all of the defects found on most gnex, i love the nexus ecosystem. almost every ROMs out there support Nexus, and Nexus line has the most amazing developers out here. :) it's a PITA if you don't have warranty from samsung though, just in case something not wanted happened to your display or even your device.
[Samsung Galaxy Nexus] Kazekage Gaara:
Thanx for the help dude. We finally got the Galaxy S2 :D Actually, all of this was for a very good friend of mine. It's his first Android phone, and we got it at a very good price with bill and 1 year official Samsung India Warranty :D And we got the I9100 "non-G" version ;)
[Samsung Galaxy Nexus] chrone:
great! i9100 is still legendary. :D
[Samsung Galaxy Nexus] Kazekage Gaara:
Yeah, it is a ROCKING phone :laugh: It was a little bit over our budget, but we got it for $450 or €350, and at that price point, S2 was the logical choice with a Super AMOLED screen :laugh: We were inclining a little bit towards Atrix 2 but the S2 has a better screen and the price difference wasn't much :)
[Samsung Galaxy Nexus] thegtfusion:
My sister got also got a nexus and her screen is perfect. No black dots or tints. Lucky her!
[Samsung Galaxy Nexus] Kazekage Gaara:
Well, since we were getting the phone from a grey market coz Nexus hasn't officially launched in India yet, we were able to examine the phone personally before buying, and we also were getting a perfect screen without any errors, but two things scared us the most. It was coming to us without warranty and the possibility that the Nexus phone will develop screen errors in the future down the line. I read many posts here where people stated they didn't have any errors initially and that the issues developed after 4 to 6 months of regular usage.

These are the things that scared us the most. If there had been official Samsung India warranty on the Nexus, we would've bought it blindly :o
[Samsung Galaxy Nexus] raptir:
Just got my Galaxy Nexus and wanted to provide my experience. I bought it from the Play Store. It came with ICS with I thought was odd (I thought they were shipping with JB). The screen has an uneven yellow tint with the top being much darker than the bottom. The screen is also very grainy.

I called Google Play Store Support and they forwarded me to Samsung who is going to replace it.

i guess there's no such option on vanilla jelly bean. :(

Green screen after replacement

Hi!

I did a screen replacement on my GNex today, at first boot up after replacement the Google logo was upside down and green(!) When finished booting the screen was completely covered with transparent green. There don`t appear to be any other issues. Did a wipe and re-installed rom (CodenameAndroid) and Franco.kernel but with no luck.

Is there any chance this can be a software error, or am i correct in assuming it to be the screen itself?

Regards

Jorgen
[Samsung Galaxy Nexus] chrone:
are you using stock android 4.1.1 from google? try to reset to factory image using yakju or takju build, search for xda id: efrant and follow his guide.

the upside down logo is weird.

the white on this gnex is not pure white especially on auto/low brightness, try to crank the brightness up a bit for instance 40% up to 100% and see if it's getting any whiter.

try to replace it again to samsung if you don't like the screen up until you can live with it.
[Samsung Galaxy Nexus] ste1164:
Erm that looks like a hardware defect D:
[Samsung Galaxy Nexus] jorgen.bruntveit:
Updated radio and returned to stock 4.1.1, still no luck :( Installed CyanogenMod and ran Color Control, seems like i dont have RGB but GB only :eek: The only thing that is quite confusing is that in bootloader the image is flipped, but as soon as the phone is within the rom it is the right way around.

So now the big question, get a new screen replacement or be patient and wait for the next gen Nexus? :silly:

here's the guide by efrant on how to do the above: http://xdaforums.com/showthread.php?t=1626895

it feels like a lucky draw, some get good some get bad. most of us in this thread has bad experience with the screen though. but that didn't hinder us to enjoy our nexus. :D

we can't tell the defects by using screenshot images since screenshot is done by software render which is perfect or the way it should have been displayed. try use decent camera and post it in here.

you could always download display tester app from google play store, it's free. test your screen with the dead pixel test, swipe to the left in display tester dead pixel test slide show to reduce the brightness down to 10% and see it again on each colors how good your eyes can tolerate the defect if there is any. :)

the perfect one should have solid color displayed on 10% brightness. but most of us get solid color on 40% upward, this thing is weak to produce solid white and especially grey backgrounds and its gradient.
