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

[Q] Galaxy Nexus Screen Looks Odd?

I just bought a Galaxy Nexus from Handtec, and I notice that there are lines on the screen that resemble the texture of linen. It's not as noticeable when the brightness it set to max, but when it's darker the lines are very visible.
For other Gnex owners, is this normal? Or maybe this is the effect of the penTile?
Thanks in advance

Normal SAMOLED behavior with white backgrounds.
Get an SLCD if you are unhappy.
Just the way it is.

Thank you. No, I just wanted to know if it were normal, since I've never owned a AMOLED phone. I'm not sacrificing this baby for anything... But can anyone else with a Gnex provide more firsthand knowledge?

I own one. More posts will get more of what I said. By all means keep reading but what I posted it universally true.

This is because AMOLED screens use organic diodes that are more 'noisy' the less brightness there is. That does not mean it actually is more noisy, it simply means that your eyes are able to detect the noise in lower brightness while not as well when the screen is bright.
AMOLED is a funky technology, it's diodes 'age' and their colors have a short transfer period (sometimes if you have a screen turn gray, you can see the previous screens ghost for a short time in low brightness settings).
But the flaws don't outweigh the gains of AMOLED producing the most vibrant colors, contrast and saturation there are at the moment. I love it.

Even though i had an amoled phone before i got the Galaxy Nexus - my Desire was amoled - this effect wasn't very noticeable. Was having the same doubts about the Nexus, thank you for clearing it up.

Thanks for this. I posted in a thread or two about this same behavior yesterday but didn't get any concrete answers. Appreciate it. Glad my phone isn't having issues.

The ghosting is a bit annoying, but strangely I've come to like the 'linen texture'. When it's subtle.
It almost seems as if by design on the app developer's side.

Hello, I'm total agree with you!
but my preoccupation about it dissapeared when I realized that the screen rotates extremly slowly. (galery, web browser, pdf reader...) with everything.
Sometimes even don’t rotate. I have deactivate all screen animations and the same duration. (2 seconds or more)
My nexus s was much faster with a beta rom with android 4.
Therefore I'm much more worried about this possible issue.
Do you have the same problem?
Thanks in advance!

The rotation delay is intentional. There are some ROMs (see Paul's MCR one) that speed it up a lot.

some people (like me) like it when the slightest tilt doesnt change orientation, its better now that its a more deliberate action.

Whilst on the screen issue...
Does anyone have or have experienced a purple haze in the screen? On my device it a purple haze like colour in the bottom right corner. This changes further up the screen until it becomes (from what I can tell) a normal colour. Hardly noticeable until the screen is dimmed, then quite apparent.
I've arranged a return as I've only had it 14 days. Just wondered if this should be expected...

like that?

Yes! Except on my screen its noticeable more on the left hand side of the phone. Is this sort of thing normal for this device?

****! I returned mine to Expansys cause i had the same issue and i tough my phone was damaged! Keep it mind my last device was the iPhone 4 which had a pretty good screen! I really don't know if i should keep this device now since you guys say its normal! My friend has a Razr and his whites backgrounds are amazing and on my Gnex they look like my screen is damaged unacceptable for a device i paid top dollar for!

I would advise you to keep it! At first it seemed awkward, but now i dont even notice it. And the fact that the black is actually unlit is simply amazing. I always look into my apps just to see the amazing contrast between the lit and unlit areas of the phone. And when you set the brightness up, you wont even see the textile lines. Trust me, it is worth it for an HD amoled screen, ICS, and a top of the line nexus phone that will always be up to date. BTW if you get the Razr instead of this nexus, i have no words...

im not getting the Razr i was just using it a reference! Im new to android and i think I am going to stick with my Gnex i just have to wait till i get my replacement back! should i root my Gnex?

So I am on my second Galaxy Nexus, and I'm on my way to a third tomorrow.
My first one was absolutely awful, with blacks looking bright purple (Phone 1: http://i.imgur.com/2bjUZ.jpg ) and now OTHER elements looking purple (Phone 2: http://i.imgur.com/1EI0V.jpg ). That's not all. My first one was somewhat free of screen banding, but this one is riddled with it in every menu: http://i.imgur.com/j2oxB.jpg

Are nothing more than standard AMOLED behaviour. They are saying that terrible colors like I am experiencing are normal if the phone is dim.
Is this true? Does anyone have ANY color issues at ANY brightness?

Good to know there are some phones out there that look great all the time
I'm not leaving the store tomorrow until I am certain the screen is perfect!

When you look at the phone in the store tomorrow, and you go to settings, don't get scared away by what appears to be "banding" in the background image. It' just a poor quality image google has chosen to use as the background. See?

Wauw that looks bad. I'm currently struggling with a grainy (gray) screen, but looking at other nexuses that seems normal. On light i can however see darker spots and lines on black screens (including boots and black images) but seeing other topics crawled with the same issue I don't put much trust in a device without it...

Oddly enough, neither of my Nexus' have had the grainy screen problem, just this discoloration

I received my 2nd Nexus today after the firsts' volume buttons stopped working. The new one has purple where black used to be, like yours, but doesn't make the experience any worse. However, when I pull the notifications area down on low brightness, the screen dims further - does this happen on yours? It's quite annoying...

Mine is okay. Not perfect but okay. There is still a little bit of purple (not that extreme like uours) but after a few days you barely notice it

on low brightness the notification tray is almost an opaque black

Same here but top bar gets even darker when notifications area is pulled down, even when brightness is set to 0. Whites are a LOT better tho.
Edit: just noticed that when taking photos, the brightness of whats being photographed affects the screens brightness. Also, top half of pages on tapatalk are a lot brighter than the bottom halves, it's strange and quite annoying once you notice it...

are all amoled not plain background?

yellow tint
I have that yellow tint that the link is describing due to the glue during the manufacturing process. I'm able to see it when looking directly to the screen. When the screen is slightly angled away, that yellow tint is gone. I hope it will be resolved on future updates.

Can't say what's your problem without any pictures but yes, AMOLED displays differ from device to device, and it's still immature, unlike LCD displays.
And yes, mine has Yellowish tint too.

This can only be resolved with a color temperature change, up to now im still wondering why the color temperature on the Galaxy Note 2 devices vary so much from phone to phone and no its not the glue. From where I live this is valid with in the 7 days of replacement provided that the next unit they open up is not yellow. But if im in a pitch black room or no 'warm' light sources there are no traces of this warm color temp.

Mine has no yellow tint, mine looks like middle area of screen is grey shaded, I checked, protector is ok, but screen middle area is very slightly shaded. Very difficult to see, when we scroll fb or youtube(down to up) then its noticable... most in plane white background...
I hope someone understand my fail English. .

Thats obviously a defect, have it replaced.

so, thats a picture,
shows that middle area of screen is grey shaded,
is that Normal?

have it replaced.

Like I already said in another thread to your query, this is normal. If you can't distinguish this from the naked eye (during normal use), this is definitely normal. I'm sure you are keeping the display in low brightness; this brightness uniformity issue exists on virtually all AMOLED displays, and the Mura Effect does have some attribute to this as well. Rumors say that the Samsung's Flagship Devices this year (2013) might feature an SLCD3 instead of AMOLED. Might indicate that AMOLED displays still need further refinement. If the shade is not so prominent, you should not worry about it then. Every Note 2 has this, those that say they don't see the shade are not looking close enough. I call this AMOLED phenomena a Samsung-kind-of-thing for a reason.

Screen issues

I've had 2 Oneplus 3's now, and am now in the process of sending the second unit back for a replacement.
This because the screen wasn't functioning properly, there was lightbleed on both and the screen had a green tint on one side and a red tint on the other side.
Has anyone else experienced issues like this? Is it a known problem, big or small? Or am I just in really bad luck by recieving a bad screen 2 times in a row.

No issue here. Wish the screen was brighter but at least its the same as my g4

The problems you're describing are physically impossible on a Super AMOLED display... and to say that it has happened to both OP3s you received is just as absurd. The pre-applied screen protector is pretty crappy, but I mean c'mon... Are you one of those guys who returns things with the smallest imperfections, or perceived imperfections in this case?

Do you have any picture of the defect. So far, your issue is uncommon one for OnePlus 3.

Woah there, I have no idea how it is possible to have the problems I have, I know that with lcd sometimes the glue causes the device to be lit unevenly, don't know if that could be the case, but it seemed a little off. I tested this using this video on full brightness: https://youtu.be/vu0mQa2EpS4
While going from. Grey to black, the pixels should all turn of at the same time, or at least, that's how I think it should be on amoled. But this wasn't the case on both devices.
As for the different tint problem, that does bother me a lot more, reading Web with a changing color if you read from left to right isn't that good for the eyes or at least It bothered me.

Here are some pictures, it's quite difficult to recreate on camera like I see them but this gives a general idea of what my issues were with the first device. The first being the screen tint, on the left of the screen it seems to be more red and on the right more green, while this is a Grey background at about 50% brightness. The second is how the screen is unevenly lit while on a solid Grey low brightness background.

I just watched that LCD test video and firstly my eyes hurt from the bright white light secondly I am quite picky and having come from the g4 which I thought had a great screen (few bleed issues though) I am quite happy. I couldn't see anything at all on my unit like you have so maybe it's device specific?
I have noticed this weird thing though and it's when I use MX player pro to watch films. I have been watching the dark night for like the 20th time on th op3 but do notice the skin tones look a little warm and when i increase brightness it gets worst. I think this is a combination of the pentile display and the AMOLED screen with a lower resolution than we would like. I am sure I remember my galaxy note 3 and wife's s5 looking like this also but could be wrong.
Overall it is strange using g4 then using op3 it's hard to explain but they are just different not just LCD / AMOLED but the calibration also. Love the blacks though it's like the phone is off when the screen goes dark. Nice.

So the screen turned black fully at the same time, well there's a logo on screen, but apart from that all black?
I know what you mean by that, I think thats in all screens, not sure, but I had it in both screens but also the problems occurred on them too, maybe that's a feature, I at least won't mind at night when the screen is that low and a bit more warm toned. I saw it on a selfie I got on whatsapp, at night when I got it, I saw her face normal, but when I set the screen brighter, I also saw that the photo also had a background! which was invisible and dark on the lowest brightness.

no issues

Didn't see a logo. Must be blind

Smallest imperfection? He uses the screen all the time and notices that all the time, how is that small imperfection? Also amoled screens are known for the issues he described. All screens have that issue. Just people like you are not good enough to notice it while others notice it easily.
