Screen defects?

After a few hours of playing with the VZW Nexus, I noticed a thin, vertical line of pixels that are lighter than the surrounding area. It's really noticeable on white to gray screens.
Has anyone else noticed such a defect on their display? Would VZW exchange it? I probably won't be able to get to a VZW store until the weekend is up, and I'm worried that they will assume the delay means that I caused the issue.

I think that's just an artifact of amoled screens in general. AFAIK, SGS2 had the same issue.

Are you sure? What I have looks more like stuck pixels; a line of pixels that are firing at a consistently higher brightness than the others. I had a Droid Charge before this phone and never had this issue.

The Charge doesn't have the same screen, it was SAMOLED+, the Galaxy Nexus is just SAMOLED.
That said, I'd need a better idea of what you mean, or how you're testing it. But I don't think I see it, and I'm pretty picky about my display.
I am a little disappointed in the odd washed-out look it has, almost like the gamma's too high.
Anyway, Verizon would probably exchange it, but you'd probably need to call in and have them ship you one. Going in-store you'll be fighting with stubborn sales reps who aren't getting a single dime of commission off their time with you.

My first unit had that, my current one doesn't. Try for an exchange, mine is perfect, but took two tries.

Is there a way of fixing it, like how you used to be able to fix old tv's with a magnet?

i have the same issue... and i can`t make an exchange because i bought at USA and know i`m in BRAZIL. =/ have some way to correct this problem??
thanks

Judging by the crickets chirping, looks like the only thing you can do is exchange it.

Has anyone had any luck with replacements? I get the vertical/horizontal line issue at lower brightness, but even at higher brightness solid colors look somewhat grainy.

I had a vertical line and some random spots with pixel problems. It wasn't visible during the day, but at night those pixel were darker than all the rest. Got a new phone within a couple of minutes in the store.

Galaxy nexus' screen makes me incredible dizzy :/

You might laugh but its true, i can't use my galaxy nexus while I'm on a moving car, and no I'm not the one driving, when I use it I get incredible dizzy, I wanna throw up, I'm blaming the pentile screen, I had a galaxy s ii which is super amoled plus and an inspire 4g which is super LCD and I had no troubles whatsoever, does anyone else has the same issue?

It probably has to do with you focusing on the text when you're moving, you get motion sickness. just take medicine for it

I did notice that effect when staring down at the screen with a certain pattern of floor tile in my peripheral vision.
Immediately got dizzy and no matter how much I told myself out was just a visual effect and that I don't experience this type of vertigo, ever... It continued
I've had several smart phones and other devices that should have caused this if I had this type of problem, but this is the first screen that had ever done this to me
So yes, I believe you are correct

As much as I doubt the pentile display is the cause for the dizziness, I found this hilarious.

It may be.
I personally can't watch DLP TVs or Projectors. I see very vivid flashing rainbows that make me extremely sick.
LED backlight LCD screens make me sick too. When the brightness is dimmed I start seeing the flicker from the LEDs. Hence why I've had AMOLED phones for almost 2 years.

Try not looking in the downward direction while your using it in the car, it helps

Your eyes probably run at a higher fps than the rest of us! :-O

Its because your brain thinks you're still and the liquid in your ears (forgot the word) is being moved around since you're in the car. If you look out the window then you won't feel sick.
Its motion sickness.

All of you are missing the point-obviously from his post he's had other phones and didn't experience the same issue, it's not simple motion sickness, it's somewhat device specific. Not that the Galaxy Nexus is the only device that can cause it by any means

because of the font, gamma settings, etc, he is having a harder time focussing when on this display. this is causing car sickness.

Could be, my personal feeling is the resolution has a LOT to do with it.
That's yet another reason the Galaxy S2 is pretty much the best phone every produced to date IMO. The lower resolution looks more stunning than anything I've ever seen on a smart phone and minimizes/eliminates the problems that come with a tighter pixel density
Still love my nexus though, more than the GS2

Sometimes when I play call of duty MW3 I get dizzy when I get a text and look at my nexus cause of the pentile....

The only logical explanation for his dizziness is that he loves his gnex so much, that everytime he touches it he gets an erection, causing more blood flow to other parts than the brain

Yeah I found the screen a little to look at coming from a super LCD device as well. Didn't make me sick just the samoled has a funny hue to it. I'm hoping the next nexus will be super ips, the one x has an amazing screen it's just a shame about the software.

I knew Pentile isn't the best, but that's a bit harsh to say that cause motion sickness.

For the next Nexus, you'll have 5 different brands to choose from.

You should see your doctor.Dont forget to take your phone with you as this will help in your diagnosis

Ya I can't do anything on my phone while in a car or on a boat. I get nausea and such. I've always been like that with phones though.
Sent from my Galaxy Nexus using XDA

I wouldn't blame it on the pen tile. You have to realise that this is a 720dpi screen compared to the sgs2 with a lower Res screen. The additional sharpness leads to slow slightly smaller font and the clarity makes your eyes focus on words and pictures more.
Sent from my Galaxy Nexus using xda premium

I'm afraid its bad news..... you caught eye aids from your phone and the prognosis isn't good.
Within 6 months you'll have full blown nexitis and maybe 6 months after that you will have to have your eyes replaced with two 5mp sensors from a gnex (irony) due to the eye aids.
In all seriousness tho there isn't much you can do, changing the gamma settings or a dev changing the frame rate or something like that may help you.
Other than that your only option is to not look at your phone when you're using it.

Nexus Screen

I cant tell if im being picky or not. I ordered the Gn from the Playstore, GSM version, I got the phone and loved it, but there were a few bad pixels. I called Samsung, they sent me another one. I got the second phone, this one has a red hue on the entire right side of the screen, enough to be annoying on brighter pages/apps. So, i called Samsung again, and they sent me another. The 3rd one... well it also has a part of the screen i don't like. It seems normal throughout, but the bottom right of the screen is brighter than the rest. Its noticeable, but especially when the keyboard is open, the left side is dark grey, the right side is light grey.
Am i being picky? Should I call Samsung for a 4th? Could it get any better? Should I just settle? No phone is perfect. I cant wait to root the damn thing and start flashing, and calling it my own.
I love the phone so much, other than the screen problem.
Thoughts/Comments please.....

call them again!!! also look for tiny black dots!
you can only see them when the screen is black and in a low light area.
so set a fully black photo in your gallery, open it and go to a low light area and look closely for any black dots you can see.

Honestly man you're gonna have problems whatever is going on with these screens. I have the same problem (not as bad) but I can notice slight color variation when the screen dims and when my keyboard is up. It is a known problem and I would just stick out to be quiet honest. I downloaded a pixel fixer (dont know the exact name of the app), but run the color fixer for 20 minutes multiple times and see if that does anything. When I notice a big difference I'm gonna get a new one, but honestly I wouldn't sweat it, even though that does sound pretty sh****.

This won't fix the issue. My screen has a heavy yellow tint and tons of black dots. I've just said **** it cause I have a feeling the screen is just made this way..
I just stay stock color as opposed the messing with the colors, because mixing them makes the tints different colors or multi colored which really drives me nuts.
I also have on my left side a blueish tint and right side red tint. Probably defective but whatever, doesn't sound like you can get a better screen so..

Yeah thanks. Honestly, the first one with the dead pixels is the best quality so far.
Otherwise you guys love the phone? I do, and I hope the devs stick around for a good while. Even if other nexus devices emerge.
Sent from my Galaxy Nexus using xda app-developers app

Oh dude I'm used to the tint already lol. Whatever man after a few days it will feel normal. Like I said try that pixel fixer app it is supposed to be good for fixing colors.
I will definitely be sticking with a Nexus line phone for sure. I am truly happy with it compared to all of the software/bloat ware phones like touchwiz and sense. It could always be worse man.

Does your screen have any "artifacts"?

I just got a refurb phone from AT&T a few weeks ago, and after awhile I noticed some weird stuff on the screen in the blacks when a video is playing. It's the only time you can see it - never when the screen is fully on or off, just in the blacks of videos. Mine looks like it has a "D" in it about 2/3 up the middle of the screen. It's stationary too which makes me think it's something with the phone. It really doesn't interfere with useage, it just bugs me and I'm worried it'll lead to something worse down the road.
After realizing this, I noticed my friend's Gnex has some similar issues but his phone is also recently refurb'd too.
Anyone else notice anything like this? I'm wondering if I should be returning this one or not. I'm just scared that I'll get something even worse off than the one I have now.

It's a common "issue" with OLED screens. I've heard some people DON'T have them.... but i'm pretty sure it would take looking through more phones than any carrier would be willing to let you do freely. My S3 has a few black spots... but it doesn't bother me enough that i'd really consider it an issue, although there apparently are some that DO find it severely annoying. I just don't see the point in fretting over something that's only visible on a dark screen in the dark.

so I'm guessing it's fairly normal then and nothing to really be concerned about?

Yes, I see the same thing (not a D but the spots) when I have black on the screen and I am in dark room. Talked to a friend of mine that has the SGS3 and he sees it too and mentioned it was common on the Infuse as well.

This happened with my Skyrocket but I noticed it after I dropped it a few times.
Stock ICS on my S3

Mine has a one inch streak across the bottom of the screen.
Sent from my I747 using xda premium

I've owned every generation of galaxy phones (captivate, gs2, gs3) and aside from using an app specifically for showing flaws on (i think) the gs2, have never noticed any artifacts.
If it's enough to detract from what you're trying to view, I'd most definitely try to get a replacement if possible. If its something you're just nitpicking on, maybe I'd let it go.
The only negative thing I can really attribute to amoled in the phones I've owned is burn in on the screen in the location of the top bar that runs horizontally ( carrier, time, signal etc.), but as it happened on the captivate it obviously hasn't been a huge issue for me, and it really isn't tbh.

I noticed it on mine as well, first noticed it watching Netflix in a dark room when the scene went dark. Now that I know where to look, I can see it other times when that section is dark or black. My unit is brand new and I've only had it for 4 days.

Completely normal for OLED tech. I have them on my GS3 but even watching a movie in the dark doesn't focus on it long enough for it to be a bother. If I am watching a video on TED with huge black borders I see it, but not something constantly in motion.

I got my s3 first before the release date even and i have that, i think.its been about 5 months now woth it and i had the same thing from day one. Even have the same D shape in the same spot with a few extra dots. I used to panic on it but now its just whatever. Never noticed it grow or affect aything in the time i owned it.

Mine had some very obvious ink marks (lines and dots), but amazingly they faded over the course of a few months. Now, on a full black screen in the pitch black it is a completely even tone of grey.
The lack of true black still bothers me, but that is a different topic. At least the blacks seem perfectly even.
Sent from my SAMSUNG-SGH-I747 using xda premium

I have those spots as well when the screen is black. It must have to do with the idea that theoretically, black pixels on AMOLED screens should be completely off. I guess the tech just hasn't been perfected yet.

Except that isn't even slightly true with SAMOLEDs... in a dark environment black is noticeably grey, and this seems to get worse over time.

vertical lines. blobs..etc

am i the only one that is noticing this? while its not as apparent as it was on t989, this phone seems to have blobs, vertical lines and other screen defects
link to the issue thread for t989
http://forum.xda-developers.com/showthread.php?t=1300133
ive went through 2 phones(one had physical defect) and both had this issue, so im going to guess its probably pretty widespread.
anyone wanna check their phones for these as well?
since blobs, lines are not acceptable on a 600dollar phone like this
To find the blobs/lines, look at grey background at night with no other lightsource than the phone itself.

Mine has a small line but it's like dead in the middle of the screen.

mine too, only 3 small blobs, and a line
the thing with these screens is that the oleds are controlled by a voltage regulator, and when you turn the brightness down the voltage regulator can't neccearily provide enough voltage to the screen, which causes the issue we have
i was hoping samsung would have fixed this issue by now..its a surprise that they havnt

just to add
this is the kind of technology samsung needs;

nothing does indeed, which is why im glad my credit card gave me a 2 year warranty on this phone
in either case, ive posted this so people are aware that this issue exists, should they take action against samsung

The 1st unit I had were free of dark lines; but I am confident that it had the mura effect as well but was much harder to find since the dots were concentrated on the edges (near the bezel) of the display; if you look carefully at all the T-Mobile note 2's, they all have the AMOLED issue. I did notice on my first unit extremely faint stains throughout the display just like in the demo unit (in black background), but the lines were not there and hardly any dots. However, the whites on my 1st unit were somewhat dull, not as bright as the demo unit at the store, and had a yellow tint on the 2nd half of the display, and a light pinkish hue to some extent at the center of the display in a full white background, and also had faint horizontal lines (only when looked carefully) at lowest brightness in a white background (which became worse and more prominent over time).
My 2nd unit, though it does have a 1cm black line in the middle of the display, with 3 or 4 dots on the top and bottom left of the display, the whites are true whites, and the display is much brighter than the 1st unit I had. No yellow tint to be found, no pinkish hue, and no faint horizontal lines at low brightness and white background! Surprisingly, the color and brightness uniformity are flawless on my 2nd Note 2 (throughout the display, white is white, even brightness) , compared to the '3' Galaxy S2's, '1' Note 1, and 1st Note 2 I owned in the past. Best of all, the build quality on my 2nd unit is also better, no squeaking bezel or back cover, and hardly any blemishes on the bezel. The light which was leaking through the home button is almost gone after a couple of weeks of use.
So far, it seems like my 2nd Note 2 is a safe and clear winner; really hard to find a unitform AMOLED display these days and my 2nd Note 2 just so has one.
Why send something back as a result of finding the slightest chance of a mura effect when you might get something worse in return.
Like many say on the forum, "I guess you can't get it all."
