Hello.
So I've noticed a strange thing while adjusting the screen brightness manually. When you slide the brightness slider it seems like there are individual brightness steps. And each step affects the screen colors differently.
Try it yourself. Like when you slowly slide the brightness slider, focus on the quick toggles background. It changes color slightly with each brightness step. It's very slight and you got to be in a dark room to notice it.
Does it happen on your note 3 too? Is it normal or is mine defective?
Thanks
That's called physics.
Colour is nothing more than light. The less light, the less colour.
Ever noticed how your eyes see everything in black and white in the dark? How the world becomes more monotone whenever there is less less?

I don't mean less colour, but different colour tint with nearly each brightness step, some brightness levels got green tint, some blue and some red. It's hard to explain you have to try it yourself.
It's best noticeable when you download some 3rd party brightness slider adjuster and adjust the brightness while seeing your homescreen and not the almost black notification panel.

I'm using LUX. Right now I'm at -56%(My night setting) and the hue is slightly green. It always makes my blue SwiftKey keyboard a very peculiar sea-green.
Which is still perfectly normal.
You are aware that screens are composed of Red, Green and Blue LEDs?
And that brightness is determined by how much light is emitted by each LED?
Naturally each step will have a slightly different hue.
The three don't blend their light into one, there will always be one of the three LEDs that is the dominant colour.

Yeah I know AMOLEDs are made of tiny green blue and red subpixels.
So in conclusion this is normal? Is this just another disadvantage of AMOLEDs display?
Thanks
I too have noticed this. However you will need another smartphone in order to see the difference. This is what I did and this is how I know that there is a slight tint.

Yes, it's normal.
It's more a disadvantage of the Diamond Subpixel configuration. AMOLED isn't at fault, it's the matrix configuration Samsung uses that causes this.
It features size difference in the three colours. As you change the brighness, one colour will overpower the other. The S4 and S5 have the same configuration, as does the Note 4.
Which looks like this:

Yeah. I started noticing it after I saw this problem on the samsung galaxy s3 mini. It was alot more obvious on that device.
Without that I wouldn't even notice it on My note 3.

Hello,
I have noticed when I look to my display in more detail I can see strange vertical lines through it. It is not very visible but I can see it better when there is white color for example in mail application, or if I setup blue color for lock screen. I wonder if it's just caused by AMOLED technology or my HW is not ok. Is it same on your devices?
Thanks

what colour are the vertical lines? samsungs OLED screens have pentile technology which kinda sucks in my opinion. basicaly it simplifys the pixel structure quite a lot so that it has the same number if pixels but rather than each one being split into a red, blue, green section they have 2 parts each alternating between red green and blue green. i think advantages are that this makes the screen brighter and colours stronger but it also reduces sharpness and seems to make the pixels more visible. i might be wrong for your case but I didnt realise this when i got the phone. still would choose it for the amazing blacks, just a shame they done have normal pixel structure.
hope that helps

Thanks. But I think it's not pentile technology. It looks like tiny straight scratches more visible on top part of the display especially visible on bright color,s for example when I use green for lock screen. I will return it to my seller and hopefully they will fix it or give me a new one.
I noticed it on my Focus, as did Engadget in their Nexus S review:
http://www.engadget.com/2010/12/10/nexus-s-review/
We did see some strange issues with the display -- while it does look handsome in most settings, we noticed some troubling inconsistencies in the panel against certain colors or tones. It was particularly pronounced on solid gray backgrounds (as you can see above). We're not sure the cause of the problem (or if it was simply an issue with the device we had), but it was somewhat troubling.

Can't decide which bothers me more though, the lines or the fact that the screen dynamically dims itself based the amount of white pixels that are displayed on screen.
I can't see those in my omnia, maybe it's only present in some of the panels?

It was quite visible in Game hub mostly on top part of the display. Or try to setup your lock screen to green.
I've noticed this on mine too. I'm wondering if it's just a bit of image retention from the live tiles on the home screen, much like you get on plasma screens. I've got a photo frame app which I'm using as a screen saver for a couple of mins each day to 'clean' the screen.
It may do nothing, but it's worth a try

cant say i can see any lines in the game hub but the green really seems to make the pixels more visible on the white 'games' writing at the top
My Guess would be that this too is due to the PenTile Matrix used by Samsungs Super AMOLED Screens. As the green occurs more often but only at half the size this might lead to this effect:
http://en.wikipedia.org/wiki/File:Nexus_one_screen_microscope.jpg
Sometimes I'm tempted to dub the Display a Super Lame-OLED but only until I see the colors next to a non OLED Display.

That's interesting. My problem looked like those tiny green vertical lines on your picture, but mine had grey colour and were very visible on top part of the display, in the center I could barely notice them. The other thing is that I should see them very close to each other but in my case they were 2-3 milimeters far away from each other, which convinced me that my HW is broken. Also when I showed it to the seller he advised me to send it back for repair.
I have bought 2 Galaxy S From the first batch for me and my.
Now I just purchased one for my father.
And his screen is much better, may be it is just the calibration
But the color seem more bright, vivid and white.
the color of mine is more yellow.
Just a thought
May be Samy improve for the last batch
No pictures and it didnt happen..
Sent from my GT-I9100 using Tapatalk
mine is very white as well, I have seen the ones with yellowing and mine doesn't have it.
May be is only that i don't have chance and the 2 first i get is like that.
In fact i don't see a band like other thread mention, it just like calibration thing.
But it is ok, if i haven't see my dad's one i would never notice
i don't think picture would reveal that small details, and will send his phone to the dad day.
Thx
Have you checked the Settings>display> Background Effects to verify both are on the same setting, and yours isn't on movie?
I read somewhere that some specific models have a yellowish colour problem on the screen..
This really shouldn't be normal, so my best answer is to send it in for repair
No yellowing on mine all looks good.
Are both phones using the same brightness settings?
On my phone, when the brightness is low, whites have a yellow cast, but on full brightness, they look very good.
Mine is white as well. No yellowish color or pink spots on camera shots.

What he described is not the problem that people are facing.
BTW Engadget are simply repeating what people are saying here. They have no information of their own and it was people here mailing them that alerted them to the problem in the first place.

I've noticed on mine that the colour temperature gets warmer at lower brightnesses. Also dark grey takes on a brown cast. On full brightness it's perfect though. No left hand side yellow cast either that I can see.
There's 60 pages of discussion on this already and the points you're making have been made there a dozen times. Do we really need another 60 page thread on the exact same issue? In the other thread there's also a code to tell what version of screen you have. It would be interesting to see if the claimed "new batch" has a different version.

The main question arises....HAS THE BANDING issue been rectified...so i can FINALLY go head with my S2 purchase ? I'm hesitant to purchase such an expensive device..KNOWING it has a very obvious banding defect...and it seems samsung is unaware of its existence!
I had to ask this question, when I had my S8500 I always set the Brightness to 0, still the screen was enough bright with vivid colors and good contrast looked very sharp and there was no Bluish tint on the screen. But here with S-AMOLED+ if I set the Brightness to mid level or higher then the screen performs well and probably beat the former screen. But when it's set to Auto brightness it seems that the screen has a bluish effect and the whites are not perfectly white, the pictures are not that crisp like it was on the former one, in this case I'd easily say that former screen was better. Now is this a feature of S-AMOLED+ or problem? In low or 0 brightness it is the S-AMOLED which perform much better but not S-AMOLED+ !
Anyone noticing the backlight bleeds in the dark and at low brightness? It looks pretty horrible on my unit. It's looks similar to the backlight bleed on the kindle paper white.

That looks like a bad case.
But yeah, these threads are everywhere.
Mine does not do that my my first one had bad light bleed I took it back my 2nd one is good almost no light bleed. You should take that one back if you can.
My G Pad looks exactly like that. I'm very tempted to exchange it but now Newegg is out of stock. =(
Sent from my LG-V500 using Tapatalk 4
Mine was not that bad, but had a blue line and significant bleed in all corners, - How common is backlight bleeding on these? Not many reviewers seems to mention it?
I'm returning my G Pad to Newegg in hopes of getting another with less backlight bleeding. I'll report here when I receive the new one.
Oh wow yeah i would return that, i have light bleed but it only drives me crazy when a game or moive goes to a black screen, i don't want to return it and get something even worst, it's a shame we pay so much money for this stuff to have screen problems.
Change the theme of the screen buttons to black and you will hardly see the leaks.
I have this issue too ;/

My tablet has a little backlight bleed in dark backgrounds in maximum brightness but I think that's normal for this screen technology. It's not that bad. Fortunately, I don't have the backlight bleed in white background. However, this is what I saw on the display on the store...

I have the same issue on mine. 7 little light projectors symmetrically placed appear at the bottom side of the screen at low brightness, 20-25%.
People say it's very common on these types of screens. The thing is how bad is that bleed effect.
Mine is like that too. Anyway if you don't see this kind of light bleed, you see it the wrong way. Set the brightness to very low and change background to white (you won't see it with black background), rotate it in landscape mode. You will see it. Those bleeds are at the bottom only. This is very weird. This is the first time I've seen this type of light bleed. Deal breaker for me. I'm returning mine.

Yeah I can see why. When you get that urge to set the brightness down to 5%, rotate it in landscape and change the background to white, you want it to be perfect. I understand....

You'll run into this situation someday. When the battery goes low and you're on Chrome, for instance. Indeed I mostly use tablet in portrait, and I admit that I wouldn't find out this issue if I didn't come here. But I'm picky lol.. So yeah. If this issue doesn't affect you then it's great.

Trust me, it doesn't. And even if someday the situation arose where I was forced to turn the brightness down to a very low level and use landscape on a white background for a few minutes, I think I could survive. But hey, you've got to do what you have to do.
I can't believe I have fricking burn-in on my screen! I have had the phone less than two weeks and have been loving it but last night noticed lines on the screen. They look to line up exactly with the thread topics list on the Tapatalk app.
I have been using the app a lot but there is no way I should have burn in happening. It's not like I have even left the screen sitting in one place when using the app. My hypothesis is that it might have happened from using the ultra brightness mode (adapt display with maximum brightness on with auto brightness turned on) in bright sunshine and using the Tapatalk app.
I have googled burn in for this screen and haven't seen anything so I wonder if I somehow have a bad screen. It did look great when I first got it. If anyone out there has heard anything about this or can check their screen on a dark grey background I would appreciate it. Thanks.

Got a new phone and the screen is actually a little worse than the original.

The lines are actually not that easy to see during normal usage and I really like the phone.

Know the feeling. It freaks me out every time I use Tapatalk.
They also show up when you use a paint app and fill the screen with +-80% brightness with the screen brightness below 30%
However, they disappear when you turn the brightness of the screen up, (and compensate the black to 80% again) so it's just a bit of an error in the led calibration.
The area below the notification bar also has it when you run the colour tests after dialing *#0*#.
It's more predominantly visible on the S5 and Note 3 because those screens have the highest contrast ratio.
I'm horribly OCD over my devices too. There's a 0.5mm distance-to-screen difference between the edges of my screen protector... It bothers me every single day! >.<

Funny you should say that I just got one of those tempered glass screen protectors and was amazed that I got it on without any dust or air bubbles. Unfortunately it is also off a fraction to one side and also doesn't quite line up perfectly around the home key. I am so tempted to try to fix it every day but I know I should just leave it alone. ?

I get more red than green, but it is only when I tilt my phone at a certain angle towards a light source - one which wouldn't allow me to see my screen properly anyways. It doesn't bother me at all during normal use though d: Sorry I can't give you any helpful information haha

What I saw on my and other notes is there is slightly blue or green shift when you look at angle. It doesn't bother me.. Not like flickering of brightness control....
Truth Behold, all AMOLED screens have a tint. Some will have pink tint, others will have a purple tint, some will have green tint, whereas others will have yellow tint. The tint should only be moderate, anything excessive is sure to be defective. These are inherit problems in AMOLED displays, some will not notice the tint as everyone's focal vision is different. Most unboxing videos from Day one will show the tint without the Reviewer's comments. The only reviewer that seems to comment on the hue is Erica Griffin. The newer AMOLED panels are still a lot better than the years before. Enjoy your Note 4.
Make sure your display is set to Adaptive Display for best results.
The custom kernel I'm using on my galaxy S4 has colour tuning built in. Are there not custom kernels for the note 4 that have this also?
Same with my old S1, and my old S2

I don't know the cause of yours. The cause of mine is that the phone is a year old, and the blue pixels wear out faster than red and green, but tweaking the blue fixes it.
Just tweak the green down a bit on yours if you've got a kernel which can do it.
My screen looks horrible without tweaking the blue, and totally perfect with more blue added.
Edit: wait a second... It's perfect when looking at it straight on? Because that's normal if it changes a little when you turn the viewing angle. Only do calibration if it's got a tint when looking at it straight on.
Every Note 4 Owner has a tint somewhere on their display, whether its a pink tint, purple tint, blue tint, yellow tint, whatever the claim is; this is due to the fact of how these displays are calibrated. Viewing the screen from a particular angle usually corrects this, has nothing to do with the subpixel and life expectancy of certain colors on these latest AMOLED Panels. The Blues and Greens are now engineered to last long equally together in the current Note 4. The tint many are describing is to do with the gamma correction. Color accuracy is there, though based on the manufacturing dates the area of tint will vary. I was able to confirm this on '4' AT&T Note 4's all having the same pink tint in the same location. The AMOLED Panels in the Note 4's are far superior than its older gen panels.
It's good to know that there is a mod to adjust the amount of tint. Wish Samsung could have done this job on their end.
