Dirt and lines under screen

I noticed as soon as I turned my Nexus on today that there was a line across the screen that looked like dirt under the display.
It is only noticeable on low brightness but the auto brightness set the phone to minimum when I turned it on so I saw it. I can only also see it on bright backgrounds like the forum - it is not visible on dark backgrounds or the home screens.
Does anyone else have this issue? I will return it soon and get it replaced but I am wondering if this is widespread or I was just unlucky.
Try turning the brightness right down and looking at this page and see if you see any lines/marks under the glass.

I have a line as well but it's quite small so I'm not really bothered.

Few very feint lines here too. Setting phone to fixed second lowest brightness setting and they vanish though.

This issue is on the gs2's too.

if you go to every forum of a phone that launches you will see the same complaint. its a plague

I can also see two faint grey vertical lines on either side of the screen if I have a light (white) background and brightness settings 1-3!
I haven't come across any other issues, I only noticed it after reading this thread and now its in bugging me. But I love the handset.. better than I expected!
Are these lines normal or do I have a duff handset? I have a couple of weeks to change it if necessary but I am also aware of the stock availability due to high demand.
Anyone else in same situation (O2 UK handset)?

I have the same issue on the lowest brightness, but not on the highest. It is also very faintly noticeable on my SGS2 on the lowest brightness. On my Omnia 7 (samoled) it is also very visible on low brightness, I think it is an amoled thing.

Exactly even the iphones with it's tinting issues SGS2 with it's Blotches in the dark
and the glass isn't perfect around the bezel
people just look for this stuff

I don't understood if this lines means defective screen or if all phones will have this lines.

I have the same thing on my Galaxy Nexus. I guess it's just a thing with Super Amoled screens, rather than a defect.

+1 Just as I said in my post above I have 4 amoled screen devices and they all it to some effect. Do not worry, your phone is fine.

could someone please post a picture so i can see what you guys are talking about? i'm curious to see what it looks like since i don't notice this on the samoled screen on my nexus s.

I had that issue with 2 evo screens. I would also get dead pixels or blotches.. Just have to get lucky with one I guess.

why is fine if it seems to have a problem?
do you think that it is normal to have lines on the screen?
can you tell for sure that every phone have that lines?

I have the same thing on minimum brightness. Its best seen by using a white image as wallpaper and having nothing on your far left and far right home screens. I have many vertical lines. When I scroll the home screen all the way over to the left until I see the blue gradient appear, the gradient varies in shades exactly where the lines are.
I noticed it as soon as i first powered on the device, same as the OP, as it was set to minimum brightness but I dont generally notice it any other time. I dont recall having the same problem with my galaxy S2

Galaxy Nexus Camera Viewer

I got this phone last week and love it.
Anyway, I noticed that when I go to camera viewer in the dark or view a black image I get a gradient white to transparent line from the top of the screen all the way across. Is it normal or Am I the only one who has this problem?
See the attachment, so you can see the problem what I am talking about. See the mark on those pics.
Should I return it??
Thanks!

Yes, I get exactly the same thing. Only noticeable when the image at that end of the screen is completely dark.
It doesn't show in the actual photo.
I wouldn't return it as it doesn't affect the result and it seems to be only one pixel wide.

Darn near $800 phone... If I order it and don't have absolute perfection, it's getting returned.

I am glad to know that I am not only one here. However, I like to know how many people here have this 'not-really-problem'.
Anyone, does your nexus have a similar issue to mine? If so, please post here (just say "yeah, I have that, no big deal" or whatever)

Mine has it as well, and it appears to me to be the same color gray as the background for the camera UI, and this is just the edge of the "view finder," I am guessing that the coder for the camera miscalculated where the screen edge would be...

Bump

Thanks!

Is my screen deteriorating?

Hello everyone,
I've had my GNex since last February and just today I noticed something odd with my screen. Anytime I bring up a grey sub-menu it seems that there is weird fragmentation or pixellation of the grey shading longitudinally through the menu on the right side. Please see attached screen shots for a better idea of what is going on. I realize that the issue is faint on these screen shots, but it is really very pronounced on the actual screen itself. I'm concerned that my screen is dying and was wondering if anyone else has experienced this. I still have warranty for a couple more months. Thanks!

If it is indeed a hardware problem, it will not be visible in screenshots. Only way for you to show it would be to take a picture with another camera.

Interesting. Because I can definitely see it in the screen shots since I know what I am looking for. I'll try to post more shots with a circle around the region I am talking about.

If you can see it in screenshots it's a software problem. If you can see it on your phone's screen but not in the screenshots then it's a hardware problem. take a picture of the screen so we know what to look for too.
I mean, I do see oddities, but they look a kinda like compression artifacts
Edit: Hmm, I do see a strange horizontal line in the second picture..

This is an issue with 4.2. I believe it is documented as well, but since I'm mobile I can't get the link. Its just a software glitch and nothing to be overly concerned about

Oh I see. Okay thanks everyone.

anyone else have issues with a consistent gray onscreen?

My phone seems to have a gray issue. the lower 20% of the screens grays are much darker when it should be uniform. I can see that in horizontal view that the gray status bar gets noticably darker towards the affected area.. Whites also have a very veryyy slight pinkish purple tint. This is my second replacment S4. Is this common? Or should I deal with it since probably majority of these amoled screens suffer from this?
EDIT: whites have a pinkish purplish tint ONLY in the affected area. The unaffected area of the screen has perfectly correct colors as far as my eyes can tell

Yep this seems to be a common problem.
My s4 has this and lots of other people have reported the pink tint with their phones.
I'm on my second s4 as well. The first one had faint vertical lines on the screen.
Hopefully Samsung comes out w a fix for it.
The galaxy s2 had a similar issue where the left side of the screen had a yellow tint and it was fixed w a new update.

Thats dissapointing to hear. The screen is so beautiful usually. Then I notice the pink when reading websites or greys on the reddit app. Either I stick with this or go for the HTC one I guess

Yeah I was thinking of switching to the htc one as well but I really don't want to give up the 5 inch screen, user replaceable battery, and micro sd slot.
You can try another exchange but there's no guarantee they you will get a better screen and you may end up with another screen issue.
Hopefully we get a fix from Samsung on this.

Thats EXACTLY my problem right now lol I dont want to leave this 32 gig I just bought to waste, and the battery life and a 5 inch screen is too awesome.

seems like most s4's have a slight pinkish tint to some degree.
This reviewer's phone has a slight pinkish tint at the bottom.

Yeah I had this issue, I did three exchanges before I found one that was good enough for me to live with
I'm just sayin

Against my better judgement, I decided to try for another replacement to see if I could get a better screen.
No such luck. The third replacement still has the pinkish tint but it's at the top instead of the bottom. However the tint is actually worse than the second unit I had.
I'm pretty much done with replacements now and will just live with it.
Hopefully, Samsung comes out with a software fix for this issue.

Yeah they threatened me with " after this exchange, you'll have to go thru Samsung warranty" statement. I said well I'm not leaving out of this store with another screen like this. So I made them open the unit and make sure the issue wasn't prevalent or as bad as my previous unit. Good thing the first one they opened was acceptable for me to live with....... By the way it's not a software issue. Somewhere there are some inconsistencies with how the screens are manufactured.

I know it's a hardware issue, but I'm hoping Samsung can come out with a software workaround like they did with the galaxy s2 yellow tint issue.

The yellow tint issue was a bit different because the tint was applied throughout the entire screen, whereas with this issue it's prevalent in different areas of the screen. The only update they can issue to remedy this would be to replace the entire screen.

Actually the yellow tint on the s2 was on the left side of the screen, so the s4 issue is basically the same.
You can do a Google on it. There's a huge thread on xda s2 forums about it.

Hmm, I could be wrong on this. Either way, update or not, I'm happy with my current display. Here's to hoping for a software update that'll fix your issue!

Stuck / Dead Pixels

I have had over my phone over a month now , sharp panel vertical lines poor battery. However i have noticed today i now have 3 stuck pixels close to center of screen. I haven't had a phone with stuck pixels in over 6 years and i was wondering if anyone else has any ?

I've been lucky enough that my last 3 phones didn't have dead pixels. It's actually shocking to me. Generally, anything with a screen I have to return at least once.

well i used to be the same always purchasing screens with dead pixels and returning , talk about bad luck . This is the first screen in years ive seen dead / stuck pixels on and not to impressed , specially couple with vertical lines (Sharp panel).

My screen is all good here, but I have heard of many people exchanging this phone for various screen issues. First I've heard of dead pixels though!
These lines, what do they look like exactly? Just curious as I see that mentioned a lot..

What vertical lines are you referring to that bothers you? Can you take a picture of them?
BTW, I have none of those issues.

Looks like the touch sensor matrix. My iPad air 2, NVIDIA shield, 2015 Moto G, and 10 have these in horizontal and vertical if you look close enough. If they're the same lines, then this is normal and is needed to detect touch.

I see. I can kinda see them on mine. But I had to turn the screen off and get under a bright light. Never would have known. Are they more noticeable on yours??

for me they were very noticeable when i first powered the device on , viewing images or web pages with white background they would appear grey. They settled after a few days but still noticeable from time to time. Maybe i have just got used to them
Realized myself it was matrix and part of the tech , did consider rma at first but didn't want to risk the pink tint

Have a white pixel
So today morning I saw a dead white bright spot
May be dead pixel or even a broken pixel due to pressure
To be frank I didn't had it when I bought this month ago
I would like to say that I was playing gangster Vegas for around 3-4 hours yesterday night and when I woke up in the morning I saw it.
Have tried jscreen etc etc nothing worked. Applied pressure also that even didn't work
Any suggestions?
