Display Artefact/ghosting line on lowest brightness - Samsung Galaxy Nexus

I have a diagonal line that runs along the width of the display it runs at a slight angel, it can be only seen with the display set a its lowest setting and running a black image in a very dark room. I have taken the phone back to three (solihull) who after 3 goes of trying to see it are aware of the problem and acknowledged it. They checked their demo phone which didn't have the problem. They have contacted their Samsung rep who I am awaiting a call from.
Does anyone have a similar problem?

This is normal with AMOLED displays.

the thing is, my GS2 doesnt have this "problem" on the lowest screen brightness.
I compared them last night side by side and its very noticable on my Nexus
That said, i've already accepted the fact that everyone else has some variation of this "issue" but im more curious on what the Samsung rep has to say about it. I'm also curious if its more visible on some devices as opposed to others.
I put my brightness on a static settings so it doenst effect me much (I can see it a bit on dark grey backgrounds) but i'm just imagining people who use auto brightness cause there's NO way you can miss it on whites/greys

you must have a magic Galaxy S II then, because it is a known issue with AMOLED screens when running at low brightness.

ill try and take a picture tonight with my devices side by side
honestly, anyone would be able to spot it out if you saw them in person.
Either my GS2 doesnt have the issue, or its VERY hard to see. I took long hard looks because i was really debating if my Nexus was defective - if this is just how it is then im willing to accept it - i just want to make sure we're not part of some funky batch

And if you said they tested the demo units, thats also my observation. Some screens have it more than others (others being almost not visible) and some inbetween

It may be a known issue, but that doesn't mean it's acceptable. I've not experienced any issues like this on either of my Fascinates. I'd certainly return mine if there were any screen issues.

I understand the artefacts you mean but this is a single bar about 3mm thick its not dead pixels like the three store suggested otherwise it wouldn't matter about the brightness it almost looks like something is pressing gently against the screen. I have tried to photograph it but my camera/me are not the best.

yeah its pretty much like that
it's like...grainy with weird colours. I wouldnt say i see any thick LINES, instead it reminds me of throwing paint on a wall and letting it slide down. I'll try and take a picture tonight with some high res camera so you guys can hopefully see what im talking about
unfortauntely its not so easy for me to get a return since im in canada and i bought mine through Handtec in the UK - im pretty sure RMA-ing is a huge hassle and wait, plus im not sure if i have to pay for the shipping

Its not like that on mine.

lol i took that pic with my G2x, its not as extreme as that in real life.

An OLED (organic light-emitting diode) is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compounds which emit light in response to an electric current.
It;s Organic. Each row of organic pixels may have slightly different tolerances to voltage than the next, hence you get dark and lighter rows varying to different degrees on different screens.
By all means take a chance and see if a replacement is all the same tolerances with no darker or lighter lines or if it has lots of them and looks like a striped screen. I don't think its a "defect" as such, its just a "characteristic" of AMOLED. If they wanted Samsung could measure the tolerance of each OLED to a very accurate level and there would be no dark or light lines on any screen. It would be very expensive though, so they fall into a catagory of acceptable or not.
Thats just my opinion by the way.
edit: Im actual glad so many others are questioning this too. I feel less pedantic now. lol

Bear in mind that any replacement you get may in fact have a worse screen. I was lucky when I got my replacement phone (replaced due to volume bug, nothing to do with the screen) and my screen was luckily better. You may not be so lucky.

Indeed

well i just got my nexus today and as expected noticed a small transparant line running down with screen with auto brightness / low brightness. So i turned it of and manualy set to around 55 60% defintly cant notice it now just bummer cant use auto brightness .... will have to see how battery holds out like this as i luv this phone

Pentile for the anally observant / S-LCD

Hi, I really want to buy a Desire but when I tried it in a store I could easily notice the fuziness caused by the Pentile subpixel layout. This was on white text on a medium coloured background - I've read it's worst on black/white. I also looked at the Galaxy S and the fuzziness was much less noticable - I just hate the look and feel of that phone.
The problem is I have a pretty low tolerance to small details like that and pretty good eyesight, so I was wondering if anyone here is as anal about visual flaws as me but happily lives with the Desire's screen? I want my next phone purchace to last a couple of years at least...
I also thought it might be nice to wait and see if HTC release a Desire with a S-LCD screen - sharpness wins over deep blacks for me considering the other potential flaws with the AMOLED screens. Any thoughts?
(If the Wildfire had either an AMOLED RGB screen or a higher resolution LCD then I'd just settle for that - it looks sexy enough to live with the lack of power.)
any thoughts? eh, sure. I don't see the the "potential flaws" of AMOLED screens at all. Sure a true LCD display will have sharper definition for black on white text, but I hardly would clal my Desire screen blurred or fuzzy. I think its fine. I do a lot of reading on the net too and its absolutely fine, but you are right an LCD like iPhone is sharper for text.
I prefer the colours and the perfect blacks myself. Makes using the phone for watching movies etc a pleasure. If you use it just for very small text though, get something else. If your as picky as you seem, you will definitely have problems with this one with its amoled screen. I won't even mention the over saturated colours or the pink hue when viewing grays. You won't like that either.
i compared the screen on my desire to my friends new iphone 4 and honestly i could only tell the difference when i got so close it was physically hurting my eyes to focus on it, i really think that the screen on the desire is top and i dont seem to have much trouble with it in the daylight either for some reason
By potential flaws I meant the uneven & relatively fast fading and the burn in that some people are reporting.
I looked for the pink hue in the shop but couldn't notice it. Isn't that a hit or miss thing?
OLED is a major selling point for me. But then is resolution (<3 my x50v)
Anyone think the Desire with an S-LCD would be a big improvement?
Yeah, daylight didn't seem to be an issue at all, compared to other devices I've used over the years.
I definitely see a huge difference between Desire and iPhone 4 though. Desire is actually about on par with the previous iPhones in terms of actual blurryness, but the fact the pattern is staggered makes it more noticeable.

No the pink hue effects all AMOLED screens when displaying certain gray shades. I suggest you read the sticky post all about the AMOLED Pentile display and how it works.
Is the Desire available with S-LCD? If not, whats the point? Just get yourself a phone with LCD and be happy. The power drain on a desire with LCD would be significantly increased too. Sure AMOLED uses more on a 100% white screen, but it use much less on darker themed screens or coloured screens.
I've read the sticky and think I have a good grasp of the issue, but I've seen reports from people saying the pinkness varies.
I also have 20/20 vision and this screen is fine, the only times I'm disappointed is while text is scrolling there is a visable wave in the letters and outdoor in direct sunlight you need to find the good angle to read.

I used to be very anal about my phone. And of course you might be different but for me trying to choose the perfect one / making the perfect one ever more perfect just does not work. Huge effort, lots of frustration, little or no results and even the ones you get are brief. That's the problem with this attitude - you'll just always find another flaw to frown upon.
What worked for me was taking positive action rather than getting rid of all the faults. I implemented Allen's GTD system and I'm using my phone as a collection/organisation tool. Works great and now my phone is a very useful tool instead of being just a gadget. Flaws don't matter anymore. And with GTD I can be as anal as I only wish and still happy
BTW totally agree on Galaxy S. It's so much better phone than Desire but it's simply atrocious. Couldn't bear the thought of carrying something that makes me wanna puke for next 2/3 years.

Pink hue is not AMOLED related since it shows also in software emulator (on PC) and varies among phones. Sticky post is wrong all around but arguments for that are buried too deep in long thread.
AS for OP, HTC announced LCD Desire, and I would like to see one. I can notice PenTile artifacts and don't like it (together with over saturated colors and pink hue), but phone is so good in other segments it is worth owning.
Lots of anal talk in this thread!
Seriously, I have never seen the pink everyone is talking about and I have had my phone since the middle of april. It's weird that some phones are affected and some are not.

Yeah sure the screen has some negatives about it but when compared side to side to my old iPhone's screen its blows the iPhone out of the water. I prefer AMOLED because I can turn it up full brightness and not be blinded by an annoying backlight that make sthe phone more suitable as a flashlight than a screen.
I thought I replied earlier, but it seems Opera 10.60 is a little glitchy with the forum (and in general...)
Anyway, thanks for all the replies guys. On the way home I had a look at the Desire again in another store and found the screen a lot more agreeable. I tried it sitting down, making me naturally hold it a couple of inches farther away, which makes a big difference. Plus I had more of an "how nice is this display?" attitude rather than "can I notice the flaw?"
So I came home and ordered one online. If the text bugs me that much, I can always stick to my Axim for ebooks.
edit: Still eager to see what S-LCD brings to the table, though.
Apparently, S-LCD does not stand for 'Super LCD', it is just a name of Samsung-Sony LCD factory.

Did you know that PenTile OLED was in tens of thousands of cell phones for over a year before anyone noticed that they were different? If one has to be told that they are different... well that tells me that they work as designed.
Full Disclosure: I'm one of the inventors of PenTile technology.
PenTile technology was actually designed with a specific minimum distance from which to view it. Bring it too close to one's eyes, one will see the pattern. Actually the same thing also happens with the legacy RGB Stripe matrix, but since one is used to seeing that pattern, one mentally filters it out. The same should happen with the PenTile screen, once one is used to seeing it, one no longer "sees" it, if you can pardon my circular explanation, but it's true. If you use the phone at a more comfortable distance, as opposed to as close to your eyes as you can get, the screen will appear as intended.

I definitely would have noticed it if I didn't know in advance. (I'm not trying to imply there's anything good about extreme pickiness - it's a compulsive disorder and a bloody nightmare.)
I appreciate the minimum distance thing, but obviously it varies with eyesight - hence the brief controversy over Apple's 'retina' claims. It's just going to require a slight adjustment to my habits while standing to compensate for this.
As for the RGB thing, I feel that's easier to mentally filter out because it's consistent vertically whereas Pentile alternates the relatively larger red/blue subpixels. I imagine this is why the effect was less noticeable on the Galaxy S's RGBW layout, despite the slightly lower DPI?

As above, I think this is subjective. Some people stare at their phones looking for dust, looking for a hint of pink, looking for a mark in the case, looking for... etc etc etc... If you want to treat it like that you will be a very miserable camper. It's a phone, it has an average lifespan of 2 years probably. Use it. It reminds of these people who own a beautiful Ferrari but on't drive it. just keep it in a garage and rub it with a cloth. whats the point?
I think the only thing thats variable on the pink hue thing is the persons opinion of how pink it is. not noticeable or noticeable. some people will say its not there, some people will say it sso pink they cannot even see any other colours.
I had my eyes colour calibrated in a 16 hour operation at an optical lab in switzerland 4 weeks ago, they now recognise 400 shades of pink and have 20/20 vision, so I KNOW my phone has pink. etc etc LOL

Sorry, but all your arguments don't add up. On LCD screens i have perfectly straight horizontal and vertical lines, there is no need to filter out anything.
On PenTile displays i dont have straight lines because of the pattern that is used. THAT is the problem. Lines look like zigzag-lines not straight ones. And no i'm not looking at my phone from 1 cm distance, i'm looking at it from a normal distance and i can see the pentile effect on my Nexus One. I also had a Motorola Milestone which comes with an LCD that surpasses any AMOLED PenTile screen quality regarding resolution. (while both claim to have wvga)
There is a very easy test for this. Take a Motorola Droid and a Nexus One. Place them side by side and open a webpage on full zoomed out view. You will see the difference in resolution quality VERY clearly. Anybody who claims that there is no difference is lying. You can't just imply that the eye can't see an difference because there are many people out there with normal eyesight (i'm not talking about eagle eyes here) which see the pentile pattern too clearly.
The whole topic is quite frustrating because when buying a nexus one you make one step forward (generall hardware) and two steps back (pentile).

Disadvantages of AMOLED screen

Hi all.
Last night I accidentally discovered the burnt pixels on my one year old Focus screen The sights of high contrasts Metro-style icons (such as IE, phone and marketplace) are visible on the white background as a darker "shadows" (actual color is like a light-light yellow, close to white). These "shadows" are visible on the white background in the dark only.
It's not a big deal but I'm kinda disappointed
So, my conclusions are:
- high contrasts Metro-style tiles on the home screen are evil, at least for AMOLED screens. However live tiles (probably) can solve the issue (he-he, just thought - may be it's a real reason why MS implemented and pushing live tiles? Kidding );
- periodical changing of tile location on the home screen also can help;
- using AMOLED handsets for development is not so good. The best practice is to keep AMOLED screens off all the time (what is not acceptable for development).
My Focus is one year old, but I don't have any burn in problems some reported. Granted, I don't leave my phone screen on for extended periods, but my live tile arrangement really never changed.
Now that I have the HTC Titan, I have no regrets with the SLCD screen. The colors seem more natural to me. While AMOLED screens certainly have a "pop" factor, it's not a must-have for me.
This is a well known issue that you have to live with: AMOLED will get screen burn-in if it is use for an extend period of time.
I know most of the Android Galaxy phones also have screen burn-in especially on the status bar.
My own Samsung Focus developed screen burn-in (esp. Metro buttons) after only three months of use.

How about Super AMOLED screens, is problem still persists?
I notice things on my Omnia 7. Normally if i've had a menu open for a minute or more and i switch to a black background i can see a kind of greyish imprint of the last displayed icons.

SAMOLED has it as well. I'm sure it was a big issue in the focus forums last year
The biggest disadvantage of an amoled screen is when you move to another type of screen, and notice just how gray blacks can be. Using my old focus and having the blacks blend with the bezel was so visually pleasing, and the colors had so much pop. I hear that the colors aren't as accurate, but what does that mean really? 90% of what I look at on a phone is arbitrary colors anyway; how would I ever know that the blue tiles are really supposed to be one shade vs. another, and why would I care?
(btw yes, I had the same screen burn-in problem on my focus)
Yeah i had a major burn in problem with my Omnia 7, I think it was something to do with the bright blue theme i used, i have pictures here: http://forum.xda-developers.com/showthread.php?t=973337

Wow... I had no idea of this...
I have a Galaxy S I9000 (as well as an LG Quantum) and luckily it hasn't burnt in...
Is this a really wide spread problem?

The problem is particularly bad on Super AMOLED screens.
Super AMOLED is still AMOLED.
My Vibrant, if I turn my screen on to the home screen and let it sit there for 10 seconds and then open another app, I can see the shadows on the home screen superimposed onto the app that's running. It's very noticeable, and gets irksome after a while. You won't see that on LCD screens.
The status bar is burnt in, which is noticeable when the phone is used in landscape mode because you can always see that faint strip where the status bar is (in portrait) on the side of the screen.
I set my screen timeout to 30 seconds to "preserve" the screen.

All of Samsung's displays have this issue. Perhaps you just haven't noticed it, or are just fortunate
Not really widespread, and not really a "problem" per se. Just a component of the screen tech. It burns in and shadows easily.
However they have better power management than LCD screens and better brightness, viewing angles, and outdoor visibility - as well as better color saturation and reproduction. For example, I increase my Vibrant's stock battery life by like 4+ hours doing absolutely nothing but putting a true black background on the launcher...
It's a trade-off. It's worth it for someone like you who doesn't notice it, though. It's worth it even for some people who do. It really depends on how long you keep your phone, Lol. If you upgrade yearly it's not that big a deal. I can't see myself going 2 years with the Vibrant as my primary device and dealing with it, though. It's too startling to look at at times, especially after you spend a significant amount of time in one app with static UI elements and move to something else...
If you look at the AMOLED technology, it's understandable really. All the colours displayed on the screen are composed of green, red and blue sub-pixels.
In an AMOLED screen, there is no backlighting. The sub-pixels themselves generate the visible light, hence why the blacks are so black, because the black pixels are not powered on. (Think of an AMOLED screen as having thousands of tiny tiny LED's)
However the problem with AMOLED is the manufacturers could not produce a specific chemical compound for each colour that would wear evenly. For example, the blue sub pixel has a shorter lifespan than the green. When the AMOLED sub-pixels gets used, the intensity of light produced decreases, hence there is uneven wear. The pentile arrangement was to actually arrange the pixels in a way, which as the display wears, the colours look normal. When there are static pixels displayed, a certain portion of sub pixels gets used more than others, hence why you can notice it.
In an LCD, each sub-pixel is a polarizing filter, which filters out either red/blue/green and displays it or blocks it, so an LCD doesn't suffer from screen burn in as much as AMOLED and PLASMA displays.
From day one I have only ever used my phone on the lowest setting and I have alternated every few days from red/green tiles. I have never used blue due to the low lifespan of blues!!
I don't think it's a huge problem if you are smart. I made the mistake of leaving my screen on as often as possible when I first got my focus. Once I started noticing the burn in, I moved my tiles around, put my screen on 2 minute timeout, and didn't notice any more of the burn in. Just the original images.
As Big K mentions, blue pixels are the quickest to degrade, that is why you never use a blue theme with an AMOLED display. Also, displaying white actually activates some blue pixels and draws more power, so the black system theme should always be used over white.
Every AMOLED owner should know these 2 things and it is a shame that Samsung and the carriers don't do a better job of informing their customers of these simple facts.
I cringe every time I see an AMOLED phone with a white background and blue theme.
This is why I still stick to Super LCD.
I saw an S2 get a burn in within 2 months of use. Lawl.

The solution is ridiculously obvious: turn off your screen when you're done using the phone. Duh. That's obvious from a simple battery life perspective.
Of course, I see people *constantly* who just set their phones down with the screen on and walk away. Idiots.

The solution is not ridiculously obvious because other screen types do not suffer from thsi issue, therefor the user who moves from an LCD screen to an AMOLED has absolutely no clue that this screen type has these deficiencies. They simply assume their screen will always look the way it does as long as they take care of their phone.
That is not a bad assumption. It just doesn't jive with this display tech.
I love the deep blacks and color saturation on Samsung's AMOLED screens, but I don't think I can ever convince myself to get another one.
The issue isn't just keeping the screen on. I've always used a 30 second screen time-out on all my phones, so they aren't just sitting there a ton with an image on them. Even when you have something on the screen for like 10 seconds and move to another app you can see the image shadows on the screen. Yes, it gets pretty noticeable after a while to the point where it's constantly drawing your attention.
It's actually worse than the PenTile they use in the 1st gen SAMOLED screens, TBH.

1st gen? It's being used in the Galaxy Nexus, too
It's a really useful point to raise, and something to think about for people using their phones for development. Automatic screen time-outs can be an annoyance when you're testing features (against a real device), and wanting to stay connected (in visual studio) to the phone for debugging info and deployment. I know I have my current phone on most of the day to test tile and page updates etc. so there's bound to be large areas of the screen remaining static for long periods of time.
It's made me think twice about getting a Lumia (which I assume would be prone too) for this reason
I'm surprised manufactures don't include info on it bundled with the phones (e.g. on not having a white background) - that's pretty irresponsible.

Screen light blee.

Hi guys,
Do you have any light bleed on your screen? I have a few spots on the bottom edge of the screen.

Yea, That's Samsung for you. I was lucky not to have any on my device. And from the looks of it, it isn't too common on the Note 2014.
The Nexus 10 though. Wow. Everyone had it. It wasn't a question of if you have it or not, it was about how bad. Not to mention the blacks were blue.
I'd exchange it if I were you, no point in getting stuck with that.
Nope, no blee here.

I will exchange mine. Hopefully the new one will have no bleeD
Mine just came today and with my normal brightness setting there is only the slightest hint of bleed from one of the four LED spots on the bottom of the screen.
My panel seems perfect so far so it doesn't seem likely I will exchange it over this.
I'm pretty impressed, but I have to say the build quality is not up to par with my IPad and not what I would expect at this price. Samsung has a long way to go to produce really premium products.

I would like to see one iPad without a light bleed. So far a few I saw (including 2 which belong to my wife) had some light bleed as well. What is wrong with build quality of your unit? Mine, except for light bleed, is very good.
I think my tablet has very very slight bleed at the bottom of the screen near both capacitive buttons, I won't return it because it's barely noticeable BUT does this mean the whole screen has an issue and also could it deteriorate over more usage or anything like that.
Apologies if these are idiotic questions but this "screen bleed" is a completely new subject for me lol.

How was your exchanged tablet?
I think my light bleed is actually getting worse and I am thinking about exchanging it now that there is more stock available.
One of the spots on the bottom is about 1 cm, and while viewing movies it is a nuisance.
Does anyone have a perfect screen?

This was my worry, my screen has slight light bleed at the bottom nothing too noticeable but then again don't all LCD screens have some form of light bleed
Writting from my third Note 10.1 2014. The first one had a huge dust particle under the screen and bad bleeding. The second one had a bearable bleeding but at least 7 bad pixels (3 dead ones right in the middle of the screen and 4 stuck). This Note 10.1 has almost non- existent bleeding and just one little dust particle (invisible if you are not looking for it) but has yellow tint along the bottom edge (over the buttons) and at the bottom left corner, so when you are reading in portrait mode over white background it is impossible not to get distracted as you start one line with black over white and you finish it with black over yellow.
I truly love this device but I am getting tired of all of this. My third replacement is on its way, though I seriously doubt it is going to be a good one.
iiSo say we all!! from my SM- P600
Just noticed the blee today while watching netflix...does it actually get worse? I can live with it now but I would send it in for a replacement if it's gonna deteriorate over time
I'm on my third device and 2 of them have had lightbleed. I can't say for the first one though because the screen was dead on arrival. I think everyone should expect some lightbleed on any LCD screen. If your tablet is perfect in every other aspect other than a little screen bleeding then I wouldn't exchange it. There are too many things that can be messed up other than the screen such as S-pen detection, loose speaker grills, dead pixels, dead screens, faulty bluetooth, and the list goes on...
I have a 32bg black model and my GF has a white one, both bought at BB at about the same time. There is quite a lot of difference between the screens, mine has quite a bit of light bleed on the upper right and all across the bottom - you can see the individual leds - hers does not. However my screen is quite a bit brighter and much more "white," in side by side comparison hers looks a bit yellow. All of the screen settings are exactly the same. Last night we had them both on for 3+ hours of internet and point-and-click gaming, I had 80% power remaining while she had 56%, checking hers I noticed the brightness was at 100 while mine was around 25%. She says it needs to be that high to see the game and it does seem much darker/mudier than mine. Thinking these must have different panels because they look so different. So, light bleed or dim yellow battery eating screen, are these our options?
The pictures were taken with an iPhone 5S (flash off). The tablet's brightness was maxed and as you can see, the room was dark. Does this degree of backlight bleed warrant a return (mainly concerned of the tablet's longevity. Thoughts appreciated.

here it is. Same exact conditions. Thanks for your opinion, in advance.
The picture isnt very clear as its difficult to take a picture of properly but if the points I have highlighted are the only bit of screen light bleed you have then yeah its normal, I have pretty much identical bleed points too as do most people on here.

Thanks, I appreciate the prompt response.
And I'm inclined to agree with your observation. In particular, those are indeed the points of bleeding.
What do you make of the top corners being so bright, though? It's not like the points you've highlighted, but rather large areas -maybe this is where the light comes from?
In all honesty, I'm more concerned about future degradation than anything else. If the device is going to remain as is, I don't mind the current state of bleeding. But if this is an indication that the device will be noticeably worse in a few months down the road, then I'd like to take it back to the shop and exchange it.
Again, thanks for your time and opinion.
Much appreciated -and thanked.

No problem mate.
From what I understand Lightbleed comes from the points it's visable - it's just that for whatever reason the device doesn't block the light passing through hence the brighter areas along the bottom. And about degradation from what I have read it doesn't get worse or better just stays like that.
It depends on you if you want to give it back and keep trying to get a bleedless device but as some form of Lightbleed is common on LCD's it will be tough. I returned one due to high Lightbleed which was visable in a lit room and the brightness on low - that's bad Lightbleed and I couldn't accept that so I got the one I have now and the Lightbleed for me is more than acceptable. Plus the other problem is if your device is perfect apart from the bit of Lightbleed your next one could have other issues LOL.

IPS Screen/Backlight issue/bleed!

This being my first smartphone, I apologise if this question has been asked before and for generally being a noob, but hoping a recent answer would clarify the situation for me.
I know IPS screens for any type of device/product are prone to backlight bleeding, the reason I have a VA pc monitor. I did consider an amoled screen, but for the price, £300 and my intended uses, the G4 was the best option presently.
Without another phone to test it against and no photographic evidence for you guys my description is the best I can do. There are two points on the screen where I believe there is some bleeding present, but this is still subjective. The first is the along the top edge, where there is a very thin lighter strip of possible bleed, maybe an issue with the panel, where the info bar is normally present, that is lighter than then rest of the screen. I can notice it whilst watching full screen video, not always, when the bar is absent. The second is more minor, there are two spots on the bottom of the panel, either side and just above the LG logo where there is some bleed leakage, but minor.
I guess I'm asking is this common and worth the risk of replacing, or are the odds are I might get the same again?
Thanks.
Some light bleed top and bottom is going to be somewhat inevitable. On my phone it is noticeable if you look for it, but not too bad.
I have another issue with the panel itself not being uniform. The top of the panel (near the earpiece) is all bright and possibly on the touch of the yellow side of white. Lower down the screen towards the bottom left it goes towards pink.
Is yours OK in this regard? It is most noticeable with the phone in landscape reading forums like this.
I have a replacement phone arriving tomorrow to compare it to.

The uniformity on mine seems okay - using your suggested test on 50% brightness on this webpage, I have none of the other issues you mentioned (pink or yellowing), apart from that bright strip along the entire top edge under the front facing camera that is brighter and slightly washes out any colour/images on that edge.

Thanks. Another place it is noticeable on mine is in Gmail or any notification on the notification bar in landscape. Almost as if one side of the screen is a different colour to the other although you won't notice in photos or videos. Only on white/grey backgrounds.
It sounds like all you are seeing is the backlight bleeding through, this will happen to some extent on all LCD's. I tried screen test on the play store and on the black background test I can see a faint bar of greyish light right at the top of the screen. Unless you go AMOLED I think any replacement phone is going to look the same.

Hopefully a replacment will be an improvement for you.
I'll see a few days how this bleed works out for me. Would get an amoled, but the prices plus a lack of microsd card limit any options for me. Since testing lcd monitors, always try to avoid them now because of the panel issues that are inherent to this tech process.
Good luck on any replacment.

There's been a few good deals on the Galaxy S6 (around £325 unlocked) but all the reports of poor signal puts me off (and of course there's no micro SD). The G4 seems very strong in this regard, only phone I've ever had that works in a few of the blackspots round here (all other phones report no service) Some reviews even mention that it is a bit deaf.
AMOLED isn't without its own issues though.

Yes, definitely around the middle-right-lower portion, pinkish presence even in that picture. You still within the retailer warranty/return period? If so, don't hesitate to return it.

It's not that obvious in real life, looks worse in the picture to be honest but I still can't live with it. It'll be going back when the replacement arrives tomorrow. Hopefully the replacement is fine otherwise I won't know what phone to get to replace it with. I can't get over how good the signal is now on it.

Replacement is way better. It's definitely a keeper. Has the slight 'light bleed' that you mentioned in your OP but the panel is at least completely uniform.

Green tint on greys

Is this normal? Greys have a green tint which is really noticeable on low brightness. Is this a limitation of AMOLED? But I don't recall this issue on my 6P or Note 4.
Hmm. Not having this issue...
Greys are really greenish. Though it happens only at some certain brightness level (a little more than the lowest).
The panel apparently is of low quality and has issues with greys. It's detailed in the anandtech.com review
Not noticing this on mine either.

I may have a slight tint on mine on greys, only on one half of the screen though. I'm colourblind so it could be green. I'm thinking it's more purple-ish though...

Yes what I had experienced from my last 3 phones I.e galaxy s2,s3,s4,s4 mini,s5 all of em which had amoled screen all have this thing. Its like if u seen u can't able to unseen. But its hard to notice. I think these displays are rather builded like this to work. Even my brother's new s7 has this thing.

On only part of the screen though? I know when tilting AMOLED displays that can happen but head on I don't know. (I've avoided AMOLED up until now because my last couple experiences with older ones was not so nice)

Guess that answers that, cheers!. (although mine might be right side of the screen, not bottom)
On my phone, the bottom part is also "greener" than the upper part. This is especially visible when brightness is set low (which I do when not outside, because it totally suffices).
Do more people have this problem?
Would returning the unit and getting a new OP3 make sense, or are these unevennesses typical??

I'm wondering if it's just an AMOLED thing... If it's really really bad then you may be better off RMA-ing it of course.

The findings on Anandtech have nothing to do with the quality and everything to do with the calibration, which is just software.
Hi, is it darker like the pics from my thread? I think I have the same issue on my display, just at the middle of the screen.
http://forum.xda-developers.com/oneplus-3/help/dark-line-oled-screen-t3402293
One thought came to me: In the upper half of the OP3 are the parts which get warm when the phone "works". Perhaps the part of the screen which is warmed up regularly loses a bit of green tint, while the lower, colder part remains as it is??? Just a thought...
I get a weird purpley/dark colour on greys and when scrolling white font on black background, but only on minimum brightness.
After reducing brightness below a threshold (just above the minimum) the colours across the display seem to shift

I got my replacement phone today. And. The display is even more worse. The colors are uneven, like some of them have here. The bottom is greener and the top slighlty pinkier/the correct color.
Argh. That's what I'm afraid of (sent my device in for replacement on Saturday):
That, as a replacement, simply someone grabs a box with a new device and sends it to me, without testing.
Edios, what did you write in the service request as your reason why you want a replacement? Did you write about the display problems?
Welcome to the lottery...
Does anyone know: If the 2nd device also has a defect, and the 14 day return time since I got the 1st device is already over, can I demand from Oneplus that they take back the 2nd device and that I get my money back??

I didn't even mention the issues, Amazon immediately gave me a replacement.
The problem is, they provide only a single replacement and now insisting to give a refund. But I want this device cos there's no other device that I'm interested in. And it's out of stock also.
For what it's worth, these sound like typical AMOLED issues. There are long threads in the Galaxy S6, S7, etc. forums with people experiencing the exact same thing. AMOLEDs just seem to not be as consistent as LCDs in the quality control department and it's always just the luck of the draw whether you get one with green or pink tints or not.
