I think that he meant this:

I dont think he is refering to both yellowish screens or banding.
I'm having this issue too. It doesnt show itself unless the screen brightness is turned down, and especially an grey background. There will be faint large vertical stripes. It is as if the backlighting is uneven. Increase the brightness and it'll go away.
Seeing that i do not have the yellowish screen problem, no stuck/dead pixels and no bluish tint problem, im very reluctant to send this phone back for a replacement due to this problem. Its something that i can live with.
I have had my note for about 2 weeks now and noticed a barely visible thin vertial white line about 1.5cm from the left edge of the display . It is only noticeable on white display at low brightness and if you know where to look for it. I am not even sure if it has been there from day one. Anybody having seen anything like this? I am not sure if this is a defect or acceptable since it is barely visible and not distracting unless you know about it and look for it. Any comment will be appreciated.
update
Today I played with the brightness control to see if the line will still be there at different settings.From automatic went to manual and gave it full brightness and then back to minimum. Opened applications with white background and the line is gone.Hope it will not reappear
hello everyone
I have an issue with my i9500 screen.
I installed Display Tester app from Play Store. I run the Defective Pixel Detection test.
In red, green, and blue color, it doesn't have any problem (or it's just my eyes). But, in white color and grey, there's kind of darkish red tint with gradation in upper side of screen. So basically the screen appear brighter in the bottom but darker in upper side. I've tried turning off auto and maximize the brightness, but the problem is still there.
It's very noticeable too in Viewing Angle test.
So anyone have this issue? and (perhaps) the fix?
mine is running on latest OTA update (XUAMDK baseband and XXUAME1 build number)

I've had 2 devices with this issue, I'm pretty sure is a hardware problem so I don't think an update will fix it. You should go for a replacement.
I have the same problem but in the left side of the screen it has yellow tint while in the right side it has pink. I took it to samsung customer service today, they told me we will call you once we take a good look at it.
Same issue with mine

mine is darker with a pinkish tint on the top half.
It is a hardware problem. Hopefully my replacement phone does not have the problem.
Since last week I am seeing horizontal banding (dark/light banding) on the screen, this is very notable on white backgrounds/low brightness.
Not sure if this is a result of screen burn in, any body seen any thing like this? Is this a hardware issue?
So I recently noticed a thick but light band running vertically through the center of my screen
Is this normal for this phone? It's only visible on dark gray backgrounds and its still so light you can hardly see it, but it is noticeably there.
I don't want to rma for a refurb and I can live with it but I don't want this to be the sort of issue that gets worse with time.
