Display Artefact/ghosting line on lowest brightness

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

LG I want my yellow back

So, I love everything about this G Pro except one thing it was bought for. The display of it is a disaster. I mean it's the worst LG smartphones' display in some years. I prefer to use indoors @ 60% brightness with autobrightness on and in this setting everything looks so dim, grey and almost unseen-able. Especially yellows, I mean there's almost no yellow colors @ all even at 100% brightness, but at 60% it's even worse. And to not be a windbag I've snapped some comparison photos of G Pro next to another LG smartphone, which has, IMO, the best screen ever. When you hold them both in hands its no question which one you'll keep to yourself being forced to choose
So if LG will continue to mistakenly set their display's color temperature to 10000K, I confess my next phone would be HTC or even Motorola. I don't want to see ppl faces of corpse skin colors, and green everywhere where yellow supposed to be

I'm at 25% brightness and I can see the yellows in the pics you posted just fine.

Your comparison phone is over-saturated and blown out. I am looking at the images on an very expensive and calibrated IPS at work. Neither phone has it right, but the G Pro is closer in comparison. The G Pro certainly is cooler in color causing the yellow to become green-ish. But comparing an almost green image looking for yellow is silly. It won't make people look like corpses... you can test that too, with pictures of people... odd you didn't include that in your image set.
Edit:
Wait, hold the phone, there is one person in your test, and they don't like like a corpse... imagine that.
Edit 2:
Wow, if you really can't see that the G Pro looks better, you need to have your eyes checked.
Can you really not see how **** the other devices screen looks?
What ever you used to take the pictures is very grainy too... just fyi.

Is that a nexus 4?

You don't see my point or don't want to. Look on your expensive IPS at this image http://www.google.com/search?site=imghp&tbm=isch&q=5403393757_b5b17ea28d_o.jpg You see? There's tons of colors in it. Then transfer it to your G Pro and open, it made all color turned into shades of blue. It's intolerable. Well, Nitro also make this image bluish, sort of, but in way no as blue as G Pro
Nitro has its fallacies, of course, it can't show every possible color in the Universe, as I remember it covers 87% or 97% of sRGB when G Pro covers 99% sRGB. But Nitro has col.temp set around 6800K and all images looks true to life. I haven's seen one person who was dissatisfied with that screen, even photographers. And G Pro has around 9000K, it's way too much, the white percepted as grey, yellow almost gone and turned green, oranges turn into cherries and etc

No, even there it has slight green tint, and white below is blueish, you must have good IPS monitor or mobile display at hand to compare. When you compare the difference is stunning and eye-popping.
Also, in original post the second picture is https://play.google.com/store/apps/details?id=com.gombosdev.displaytester showing yellow on both devices and in archive all other main colors like white, red, blue. My concern is yellow and white because the white is what you looking at most of the time

No, I don't think so. Every other youtube review unit had the same cucumber-blueish tint on white background, EVERY. So it's LGs settings that are faulty.
Do you have any spare phone at hand? Like HTC One? It almost perfectly calibrated. Go to some place, put the same white or yellow wallpapers on both devices and compare which unit will be more eyepleasing and easier to look at. I'm sure the other phone than G Pro will be
We're waiting for anandtech review, pity that he doesn't even look at G Pro, it even prefer noname Oppo Find5, it means bad for LG, it's bad marketing that even anandtech doesn't review their phones

I have yet to find a single review that had anything negative to say about the display on the Pro. The worst comment is that it's almost as good as S4/One. I even saw the color accuracy praised in a review. I don't doubt there are likely exceptions, but not in the ~10 reviews I browsed through.
My co-worker has an HTC One and while due to size his screen looks crisper, the Pro looks damn good otherwise.

Checked out that link, everything looked perfectly like they saidit was supposed to even at lower brightnesses...maybe u just have a bad screen, i watcj lots of vids and pix on mine and they all look fine

"The screen is very nice." First sentence in what you quoted. Not a single one of the reviews mentioned an issue with the color balance. I personally do not see an issue with the color balance. A number of other people in this thread don't see an issue with the color balance. I definitely saw an issue between the two in the picture, but my phone doesn't look like that and from the sounds of it.. neither do most of the other people's. So, if everyone else is telling you it's your phone...

Why are you so effing worked up over this? It's not nearly how you describe. Almost everything you have pointed out is either slanted/strategically chosen quotes from actually solid reviews or pure hyperbole.
Just sell the flippin thing and move on, your exaggerated criticisms are going to scare off developers that we desperately need.

Screen tint

The screen on my 8.4in Tab S is bugging me, is it just me?
With all "super enhanced" colour settings set to plain and boring colour, I keep noticing a slight green tint in the central area of screen when viewed square-on, it's very subtle and seems more obvious with text on the screen, e.g. the Tapatalk forum listings. Also when viewed from an angle the display takes on a slight blue tint, despite reviews saying how good the angles are, it seems worse than the LG G Pad.
Is this just a feature of AMOLED displays or could it be a faulty unit (how?)?

I don't see it. Sorry.

There shouldn't be any differences viewed at any angle with this screen. Try this... in bright sunlight, with the screen off, look at the screen on an angle. It should look a uniform color - actually almost exactly matching the titanium bronze bezel... just to make sure there is no physical defect.
Something to note - if the screen is OK, it could be your eyes (not joking). The eyes can play many tricks - for example, seeing a lightly shaded box with text on a piece of paper that is only black and white - the box can appear to be shaded slightly red. That's one example, but there are many. And with the resolution and technology of this screen, there are no imperfections to draw your attention, like staircasing, blur, backlight irregularities, that you are used to seeing. It is a bit confusing to our physiology, and our brain does this thing called "patternization" that can contribute to us truly seeing something other than it is. This seems to be more subtle, yet more frustrating on a display that is so close to perfect.
I'm not saying that there is something with your eyes specifically. It could certainly be a defective screen. One way to find out would be to take a look at someone else's - also, if you have another decent camera, you can take a picture of the screen and look at the picture - that will usually confirm (or not) whether what you are seeing is there. Like I said, it's not you or your eyes I'm dissing. These are things I've picked up on over the years. In fact, it could ONLY be my eyes. If that's the case, I'd probably rather not know.
You can also use a colorimeter and software like HFCR to get the discreet measurements from different parts of the screen. When I have done this, I've found that there was no real difference in chromacity. Of course, that has always made me walk away thinking that the colorimeter must not be accurate. So human.
I would definitely be interested in your feedback about what you find because I've obsessed over high resolution displays trying to figure out what is real and what I'm imagining... it's an active area of interest for me.

Yes I have also noticed this. I've seen these green or pink tints on all the amoled devices I've owned. You need pretty good eyesight to be able to notice it. You shouldn't be bothered by it, they're all like that, if you can see it. But you'll get used to it.

I probably will not get used to it...

Thanks Freshman206 and SrAdama, glad (?) to hear that it's not just me, I've had the tablet just over a week and still notice it. Any slight tilt and the colours appear/shift, green, pink and when angled beyond what I'd consider normal, blue.
Have photographed it and will have another go at getting it clearer but by winding up saturation the effect becomes visible in the photos (on pc).
I'm now trying to decide what to do about it, I have an LG G Pad which doesn't annoy in this way, though it has just gone away for a warranty screen repair for bright spots (not stuck pixels)!

It is probably the antiglare coating you are seeing.. If you have the coating on your glasses and check them out, it will do the same thing as your tablet... I also noticed it appears to have a anti fingerprint coating on as well, very nice indeed :>

In shops I also have compared 3 different Tab S.
All had an immediately visible green tint, white looks not white but greenish and a bit "washed out".
I find it a bit surprising that with other devices, when they have a tint (like the yellow tint of the Xperia Tablet Z), people complain much, while here, with this really apparent tint, people tend to say: It's normal, get used to it...
I would never buy a Tab S, just because of this tint and because of the, compared to other devices, low maximal brightness.
These devices are overrated.

I ran a poll in this forum as to whether people were satisfied with white reproduction on their tablets or not. Out of 15 responses 12 were satisfied.
We have heard reports of manufacturing defects such as yellows screens, muddy splotches in the middle of screens, loose creeky backs, warped backs and excessive lag/stutter.
These are not "normal" for this tablet but represent what may be a bad run of tablets that made it out of the barn. If you are experiencing the issues suffered by the OP, I suggest you seek a replacement unit. If you have observed similar performance from other tabs in the same store that would make sense as they are likely from the same faulty production run.
When operating normally, white should be white on the Tab S. For myself and the large majority in the poll, this is the case. I have also not read any reviews by professionals mentioning this discoloration and believe me, if CNET or THEVERGE had something to rag on the Tab S about they would have.

You will see very little if any mention of an issue with yellow or green discoloration. I'm sure you are seeing what you are seeing but the problem does not appear widespread.

I just took a picture of a webpage with a white background on my 10.5 and sent it to my laptop which has software that measures colors.
The website background from my Tab S 10.5 measured at 255:255:255. That is pure white. This was a photo and not merely a screen shot.

Saw the 10.5 inch and 8.4 inch models together on display in a shop. The 8.4 inch version also had slightly yellow tinted whites when looked at directly, not as bad as I was expecting though. The 10.5 inch model had no yellow tinted whites at all, when looked at directly or tilted.

Mine has pinkish tint at the top visible when everything is white especialy when reading wikipedia

so when i switch screen mode to amoled basic, my screen have yellow tint (like warm color) and a little washed out color, is it normal or just my unit?
because when i switch screen mode to amoled cinema, everything looks saturated which is i think okay...

Yes the Basic profile is meant to be that way its not the screen problem being discussed here, if you wanted an accurate image then Basic is the closest of all the profiles. If Basic looks washed out to you then your used to looking at an oversaturate screen, if you were used to looking at calibrated screens then all three profiles would look over saturated.

I had the 8.4 and just returned it. I also had the greenish-blue tint when the screen was even just slightly tilted. More noticeable indoors with brightness set to below 40%. If I had the tablet flat on the table and walked across the room, I could see it too - screen only looked good if looking at it directly in front of you. As others have said, I think it's probably due to some coating on the screen, which explains why it would be more noticeable with the screen brightness set lower.
I've checked out a few display models at stores, they all basically look the same, though some were slightly worse than others. That being said, the 10.5" ones I saw don't seem to have this problem... if they do, it's definitely not as noticeable. Not sure if it's just an optical illusion or what, but the 10.5's look OK. I'm going to go buy the 10.5 one today, mainly for the size. I'll post again if there are any tints on the screen.

The problem was a green tint in the center when looked at head on not at an angle, seeing shifts in color when tilted is normal for this tablet. I would have kept yours if it was fine straight on.
My 10.5 had greenish yellow tint when looked at head on exactly the same as the op.

I was gonna return for the 10.5" anyways, the screen tint wasn't part of that decision, but I certainly won't miss it, heh.

Mine it is extremelly yellow! I hate this bug... It happends to me every 10 minutes, i need to restart every time to revert this.

Irregular Display Lighting (with Pictures)

I have a visible light strip at the top of the display... what should I do? I say to myself I don't care but it annoys me because I keep noticing it.
Here pictures, please check them out:

That's light bleed - light seeping from the backlight into the edges of the display. Happens when the display is compressed/bent during installation into the phone. Nothing you can do about it but get the phone exchanged if it bothers you that much. However, if you exchange it, it's the luck of the draw - you might get a better one or a much worse one.
Unfortunately, all LCD displays are prone to this, as manufacturers would have to reject something like 50% of them otherwise - I had to go through SIX brand-new 27" Dell monitors before I found two that I could live with - and they're still far from perfect.
I had to exchange my iPad Mini twice to get a good display, and my Nexus 9 three times. It's totally random. Got lucky with my G4 that has a perfect screen (though I had to exchange it, too, as the first one had dust stuck between the front glass and the display panel).
Manufacturers just have really low "acceptable quality" standards to maximize profits/units sold, as many people will never notice those issues.

I see thanks, I had some light bleed (I knew what it is didn't remember the english word LOL) on my N4 too but nowhere near this and it didn't seem like a solid strip more random...
Sent it back... hope I got luck with the next one, and hope Amazon is quick my current phones battery is pretty much dead...

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.

All true, I've heard complaints about screen burn in on with amoled screens, some mentioned in the reviews of the Nexus 6P.

I don't think screen burn is as bad as it used to be. I had pretty bad screen burn pretty quickly on a Galaxy Nexus.
Here's my LG G4, can you see the pink in that? i.imgur.com/YjmtPtT.jpg
Sorry can't post links yet. Very poor quality image, taken on my work phone.

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.
