Hi Guys - great phone which I've had a week or so now. Upgraded from the first Galaxy S.
Now I must admit to having very good eyesight (sometimes wish I couldn't see finer details!) and..
On white / grey images (download the various screen test apps to have a look for yourself)
The screen, when on a low brightness, is "muddy" and demonstrates a few vertical darker lines on the screen with mine showing quite a prominent one in the bottom right heading up about half way up the screen.
This is mostly visible when the brightness is at a minimum (regardless of auto or the powersaving options)
When the brightness is turned up it is barely visible, if at all... looks fantastic..
But.. at this point I preferred the screen on the Galaxy S which, when dimmed was more vibrant and didn't have this "problem"
Hands up who can see what I see? Any darker lines visible on your white / grey backgrounds? a side effect of this new subpixel arrangement? totally normal? some pixels not as bright in a row hence darker lines?
What do you guys think?
Cheers, B

Could you take a pic or something?
ASAP yes (no camera ironically so will have to ask a colleague!)
hold menu and press power button for screenshot off the device.
Yeah, mine set to minimum brightness and has some line artifacts like when LCD supplied with low voltage. (low brightness setting)
Easily noticeable when displaying grey colors.
I'm also using Screen Filter app, setting brightness even lower, some black points around 0.3cm is exposed at night.
Not sure those points are affected by anti-scratch film though.
Hola
I can confirm that I see the same "line banding" effect when using the device with low brightness. Like others have mentioned I also use the free Screen Filter app to get even lower brightness levels especially when reading stuff in bed in the near dark.
I would think this is a side issue with having the Super AMOLED Plus type screen but I guess only a Samsung tech can confirm.

65" long exposure exposing some black spots.(digitally enhanced)
Lowest brightness + Highest brightness.
Wondering those spots are caused by screen protector or defective screen or limitation of current AMOLED's.
You can see there is some current leak.(It should be bezel-like black if it is ideally off)

Is there a consensus we all have this "problem" - i'm on the verge of taking it back for a refund and "monitoring things"
Anyone understand the tech / spoken to Samsung?

Not sure what those black spots are... is your camera messed up? There's spots on the right even off the phone...
Also yes, pure black for SAMOLED still produces SOME light, but it's almost indistinguishable to the human eye.
Take a picture of a dark grey image on low brightness and it should show the bands the best...

That spot off the phone is on the wall not defective cam. As you can see photos are taken at different angle. And it is visible in naked eye.
Yeah I like its screen very much. That black issues are no problem in real use.
I'm very satisfied.
hello all,
i have an LG G2 and I noticed there are weird horizontal lines showing on my screen as shown in the picture (lines showing across the picture with pants)
does anyone know what this problem is?
Can't recognize any lines, but if you think that there is a problem you should make use of your warranty and get that thing fixed. Can you see the lines in all circumstances, like e.g. playing games, white background, black background etc. ?
Cant see anything... Maybe its a problem of liquid spill lr something... Better to get it fixed with service centers
Does it show up all the time in all the apps?
Its because of the amoled display, 99% of amoled displays have either these kinds of lines, or little black stains, and can be seen with black backround, the lowest brightness, and under a certain angle dont worry

Display question...
From the tiny picture, it appears to be an issue with the poster of that pic, and not your device, unless those lines are moving with sceeen scrolling and can be seen in other images.
Aside from this, it might just be 'that' image, and not a true problem.
Take a pic with your phone's camera and view that image, if you see lines on your image, then you probably have a defective screen, as the capacitive touch screen overlay does not cause these issues on their own, they have no direct connection to the screens, they are overlaid onto the screen, and not a physical part of it.
I see the lines. There's one in the first thumbnail and several in the fourth one.
I have the exact same issue on my phone after having a broken screen replaced. Did you ever solve the issue?
What's up everyone, loving this k one but how about that screen bleed though!? Yes I know there is a similar post about this, but I want to make it only about the screen bleed issue and anyone experiencing same? I am about to go get my third exchange in less than ten days
I just checked and the only noticeable bleed I noticed was by the top left of the second screen but it's small. Main screen seems ok, to me at least.

That's true, and for me it's fairly noticable on the top left, along with under the two front facing cameras there is bleed as well for me. This is my second phone.
Could be like the g2x lol
It's definitely there in the top left corner, but there's no way it would bother me enough to go exchange it.
Same here, if only there was a way to invert the color from BLACK text on White backgroud, to WHITE Text on Black Background. The fade would not be noticeable.
I went through 2 V10s and ended up returning both and going back to my M8. Basically what I noticed was slot of backlight/screenbleed issues when in immersive mode of an app. Like a book reader for example. If the background color is white, up at the top of the screen there would be a gray/black hue leaking through.
Of course once you notice it, you see it in other applications that go into immersive mode. I think there is something happening where the 2 displays meet at the top when immersive mode kicks in.
It's mostly only noticeable when the screen is like 60% brightness or less.
Unfortunately that was a deal breaker for me, even though the rest of the phone was great.
What sucks is that I'm going to have to fight a restocking fee for this problem even though t-mobile store reps saw the problem as well

I was thinking in maybe doing the same but getting maybe the HTC m9 or anything other than the Samsungs. Hate them. I will be going today to get my third new exchange since I still have seven more days left. Gets very annoying all this screen bleed issues. This phone is so beast in all other aspects. Camera, sound quality, and love the software but not as much to stock like nexus line.
I have a post here with dead pixels issues, the replacement T-Mo sent me not only had dead pixels as well, but a terrible bleed where the two displays meet. It is only noticeable when you look at the display from an angle, for example phone on the table and you have a light background you see a dark spot there, once I noticed that its driving me crazy. LG quality control is a POS IMO. This phone rocks, but is plagued by stupid QC issues.
There is nothing you can do. All phones will have the "second screen bleed" due to how it's designed.
There are two backlights. First is the normal backlight that lights up the entire display (there is no "second screen" - it's a single LCD panel). Then, there's the secondary backlight - a single white LED on the left edge of the "second screen." This single secondary backlight LED is injecting light through the left edge of the second screen and is not attached to the main backlight diffuser, which is why it lights the screen so unevenly. There are certain times when that secondary LED is on and when it is off. When it is on, it adds extra light near the left edge of the screen, which makes the notifications in that area brighter.
Try this. Turn on the Camera app and observe the buttons that appear on the second screen. Notice that the left-most (or bottom, if you hold it horizontally) button is NOT brighter at all? That's because the second backlight turns off when the camera app is running, and you only see the main screen backlight, which is even. Exit the camera app and you'll see the second backlight turn on and the bleed return. Open the camera app again and you'll see the bleed disappear, as the second backlight turns off.
Do another test. Hold the phone at an angle so the bleed from the second backlight is clearly visible, then go into the settings for the second screen, and turn it off while watching the left-most edge of the second screen - you'll see the "bleed" suddenly disappear, because the secondary backlight turns off (even though the main backlight is on). Turn the second screen back on while watching the left edge, and you'll see the bleed come back as the secondary backlight turns back on.
Yet another way to see it - power off the phone, then power it on while watching the left edge of the second screen. During initial boot, it will look perfectly even, no bleed, because the secondary backlight is off. But half-way through the boot process, the secondary backlight turns on, and you see "bleed."
Now, when the main screen is off, the ONLY thing lighting the second screen is the secondary backlight, so ALL you see is bleed (since the main backlight is off) which looks horrible.
The reason you don't see bleed at all in TWRP is because TWRP doesn't know that there is a second backlight and therefore it doesn't turn it on, since it doesn't know how.
To get rid of the "brighter left side" problem when the main screen is on, all LG has to do is issue a software update that turns off the secondary backlight when the main screen is on - I'm surprised they overlooked this obvious problem.
And here's the kicker - you know why you don't see the second screen bleed on the demo units in stores? Because the Retail Mode app turns the secondary backlight off, just like the camera app.
here's my issue, called again to T/mo and they're sending another RMA..Apart from that am having a defective proximity sensor...will update when the "new" phone arrive
That's not screen bleed. That's where the edge of the lcd panel meets the edge of the bezel around the front facing cameras. It's an unavoidable shadow.
I'm really picky about my phones, especially the screens, but I think you're honestly expecting the impossible. They can't NOT make a shadow there, given the arrangement of the secondary screen backlight and the camera bezel.
If that's your biggest complaint about this phone and the screen, then I think you're being too picky.

I know am picky, we all should be with a $600+ smartphone, in the highest end gamma quality control must be precise. Apart from that I already posted a dead pixels thread and this one has dead pixels too...take a magnifying glass crank the brightness to 100% and watch very carefully in a dark, this is my second V10 and a third is on the way
Now dead Pixels are not acceptable. But that shadow will always be there no how many times you exchange it.

That shadow was not there on the last phone and its really annoying cause it distorts any solid color that's displayed there, also it's only a "shadow" with light content, it's a bright spot with dark content. It looks worse in real life than it does in pictures

That means our models r very radically different.
way much more of an extent than I have been realizing.
Or...u have an adware prob or it's hidden
I think when it comes down to basics...each flavor has it's own heart.
Yet..No matter the carrier and especially when it's a basic LG/LGE setting....it shuld b on all.
Forgive my lack of correct wording....
I bet if u can't see it ..the ..invert....setting maybe just hidden
Again...u r stock?
K now i think....
You should Try searching for "invert" with QuickShortcutMaker app https://play.google.com/store/apps/...G6PnXP4eFRw4Tw9vg&sig2=ujB0W4bySmI1c5Qzvof0KA

I noticed the same thing on mine. I hope they will fix it with a software update. I've noticed that it doesn't seem to happen as long as the second screen is active.
Anyone else having this issue? When I switch to the dark mode it's obvious the black level from one corner to the other is not the same.
A black saturation test clearly shows the bottom row visible when the device is rotated one way and then not visible the other way.
Anyone else getting this? I'm going to ask for a replacement.

Damn, that's almost exactly the same.
I just got a full refund for mine as the shop I bought it from had no stock for a replacement. Another one on the way from another retailer, hoping the display is in better shape.
The quality control on these appears to be a bit crap.
OneUI uses dark grey on the Tab S and Note10... There are many, if not infinite variations of grey that approach black. I do art, so it's easy to notice that #000000 was substituted.
SD_black is black, OneUI simply has a dark mode. Also black cannot be uneven on OLED, because black refers to an off state.

You're just splitting hairs.
Black can appear uneven on defective OLED displays. If you use a black saturation or black clipping test you can clearly see with the tablet or phone rotated one way that the bottom row is barely visible (which is normal), but rotate it another way and suddenly they're all clearly visible, they're only visible because that part of display is defective.
I have OneUI on my phone as well, there is no visible banding and black/gray levels (whatever you want to call them) are uniform. If you're seeing any variation then you got a bad display and you should get it replaced.
Similar here. But mainly noticeable in very low brightness especially with night mode on
With which app do you test it?

Display tester, first match on the play store. Find the black saturation test
Or you can use something like the below, loads of similar tests available on the Play Store or online.
https://www.avforums.com/threads/ho...el-on-oled.2204710/#lg=thread-2204710&slide=0
Replacement arrived today and it's even worse than the first one, instead of one corner it's right down the centre of the display.
Also found an easier way to highlight the issue, using the image tester select the burn in test and move all the sliders to the left, this should give you black. Then slowly move the green slider over, you'll notice some parts of the display become green when the rest remains black, at least up-to a certain point. Took the image below in good lighting.
The Amoled lottery. I had to go through many returns before I got a Tab S3 that didn't have unacceptable display uniformity and things don't seem to have improved a lot since then.
I guess that it's cheaper for Samsung to deal with the returns of customers who notice and care about this than simply having better quality control in the first place. Reviewers of course get cherry-picked samples so the quality of the display can be praised to high heaven.
Really makes me think twice about even considering upgrading though...

hi
hours ago i found that when a blank tab is opened in samsung internet (i am using dark mode in system as well as the samsung browser) i could see the uneven black on the screen. i tried to rotate it but still the uneven black was there on the left and right hand sides in landscape mode, and on the top and bottom after i rotated it. so it should not be the ui or one ui problem
i remembered i have read this post so i revisit it and found many of you have the same problem. when i bought this tablet i have check via *#0*# to see how the black was and it's perfect. i also checked with *#0*# before replying to this post and the black was perfect too!
i am too wondering what could be the problem. i think it could be the dark mode which does not use true black (pixel off) in fact

Yeah, It's not the dark mode, this issue effects everything.
If it was just One UI I could ignore it, but sadly it's not. Essentially you have different parts of the display clipping at different black levels, even the sections that are relatively good still look patchy.
Samsung screwed us all but it's OK because it's not a popular product so nobody cares, prime example of how useless reviewers are as well because none of them picked up on it, cherry picked parts from Samsung probably.
