Are someone has same issue? and how to fix it? thank you very much.

The best I could to to check mine was to open up my email. The whole screen is white. I did not see anything except white along the edge.

thank you very much.
please try in LCD Test(*#0*# in Diagnostic Mode) select RED you will see a white border but on my device left-border is green (other sides are OK).

It's very hard to be absolutely sure on red, but on blue and green the edges are definitely all white.

I loaded your JPG onto my Focus and the left side is green. The left side is always green, but the right side and even the top and bottom can also appear green if you hold the phone at certain angles. The green can also appear purple at extreme angles.
Is this a manufacturing flaw, or just a characteristic of AMOLED screens? Could it be some sort of back-lighting source that's located along the left edge that's causing the green tint?

I loaded the picture after downloading it and then attaching it to an email.
It does have a strange tint on the left side.
I then created my own version of the image. I started with a 480 x 800 blank image in Photoshop. I filled the entire image with black at 100% opaque.
Then I stroked the outer edge with 1 pixel of white. I repeated this using 2 pixels and then 3 pixels. As you can see, it is still visible at 3 pixels, but it is starting to turn white. I think we are seeing a consistent result that means the AMOLED screens have a slight design problem that is not considered to be worth holding back this technology from the market. I know I like the display and this is minor.

darker and brighter stripes on gray background

i have this problem(maybe common in amoled devices) if i take gray pitchure and put it on background there is distorsion in grey. like brighter and darker stripes(but you need to look it realy good) for exsample download program screen helper lite and tell me do you see stripes on main gray program screen.
There is a thread going for so long,

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.

[Q] i9500 red tint on half screen, upper side

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.

True Blacks are Grey (ish)

Hi guys,
I have noticed in the dark when using my note 3 in the settings menu the bottom portion of my screen seems to be grey not black. At first I thought maybe this was a software issue so I took a screen shot and zoomed in. When viewing the photo zoomed in the entire screen is grey ish with lines (normal lines had on all amoled screens) When moving the image the greyness does not move which to me says its the screen. However! When using a pixel tester and putting a pure black picture up the screen is perfectly black.
Ideas or thoughts?

That's the way Touchwiz and Gingerbread was originally designed and Samsung kept it this way. This is completely normal and is the software. It's not an issue. It is the same way on my Note 3,Note 2 and Galaxy S II.

Open a completely black image. Download a solid black JPG from google as your test. Do the same thing with a completely white image.
Look at those images in full screen mode.
If there is burn in (which CAN happen on an LED screen, though it's actually pixel fading rather than burn in) you should be able to notice it with this test.
If you see fading in the white image, or general non-uniformity in the brightness, it's a sign of fading. (burn in)
If you see a ghost image in the black image, then something is wrong. It means the screen is lighting up when it shouldn't be.
You should not be able to see a residual image on a black screen like you used to with an old CRT computer monitor. The burn is doesn't work that way. What happens is the pixels lose some of their brightness over time. It's subtle, and if the screen is fading uniformly you probably won't notice. But when 1 spot isn't fading, you notice it quickly. This is most commonly seen with the status bar. If it's always black and the area right beneath it is always colored, then the black status bar wont' fade and the rest of the screen will.

Thanks Sir,
actually it was lcd problem

Look at the black picture. There are several fixed pixels on the screen.

My xa2(h4133) turns off the light at night and looks at the black picture,the brightness is the highest,it can clearly see four color pixels: white,red and green,one in the upper left corner and two in the lower right corner of the screen,my version number is 50.2.A.0.352,I tried to take pictures,it was too small to capture,do you have any of them,please?
By the way, look at the black picture. Is there light on both sides of the screen?
RMA, I also had some (much more) dead pixels. They replaced the screen, now everything is perfectly OK.
