Are someone has same issue? and how to fix it? thank you very much.
sorry for my bad english

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.

thank you.
I test again on black image with 1 pixel white border.

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.

[Q] Color bleed normal?

I was wondering if it is common to have a little color bleed by an edge of the screen on the nook color. On a completely black screen, I have a little bit of a green color shadow to the left of the nook bottom. Is my nook defective?

I think I know what you're describing... I get a little bit of that on the bottom of my nook when it's showing a black screen. Someone else will probably chime in, but I assumed it was "normal".

Yep, a faint greenish glow just above the n button. Hadn't noticed till now. Only barely visible with a black bacground and a dark room.

K, mine is a little more noticeable but not a big problem. Looks like it seems to be a common trait for the nook. Thanks for easing my mind.

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:
http://forum.xda-developers.com/showthread.php?t=1075364&highlight=banding

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] hardware or software issue?

hello everyone
i received my snapdragon note 3 yesterday, was playing with it till i found something, its hard to explain but i will do my best.
what i noticed is that when i move something blue (like the small bars between each alphabet in contacts) to a black space (where pixels are shut off), the blue bar turns purple for like quarter of a second and then goes back to its original color.
it is really bothering me, i waited like a month to get the snapdragon version from outside my country and now this is happening.
could it be software issue? as i remember that note 1 has a display issue where black color appear grayish in homescreen, if so, what are the best stock roms that support RDLV root with out tripping knox ? last thing to note is that it is really hard for me to return it to where it came from.
any help appreciated.
edit: it apear that it is happening with the gray color or any other one that tend to be grayish at very low brightness

This is something you'll either have to get used to and learn to live with, or sell the device. It's a HARDWARE issue, not software, and it can never be "fixed" in any way. The short explanation:
What you are seeing is the latency inherent to the design of the AMOLED pixel matrix. It takes some time for the pixels to go from black (off) to any other color (on) and what you perceive as a blur or "small bars" before it does so is this latency, and when you are driving so many pixels on a full-HD display, the latency is even more apparent.
Samsung has attempted to mask this design limitation by essentially taking true black (off) away from the user, but it only works for Samsung apps and the parts of the OS that are tied to the Touchwiz UI.

update:
it appears that this problem is called smearing/ghosting, the reason it happen is that samsung made pixels combletly turn off when it is black in addition to cutting any power going to the screen.
why Samsung did this? well, to fix something called mura effect (black amoled screen can be seen as green or brown in very dark room), this caused a delay in turning on the pixels again which caused this effect (especially with gray color).
the solution is to use an app called screen adjuster (found for free in play store) and using the following setting:
red +14
green +14
blue +14
brightness 100
contrast 0
hope this help anyone who encounter this problem
cheers

as i said in the post above, i managed to solve it but adjusting screen colors (a Little bit that it does not affect the overall colors and in the same time keep black pixels on)
by the way, are all note 3 owners facing this issue like what happened to most s4 users or just me?

Just so you know that all you've done to "solve" the problem is shift the colors up to remove black. It's not worth the loss of a true black (off) pixel state, IMO, but to each his own. All Note 3/S4 owners have this issue. Some don't notice it until it's pointed out to them, but it's a hardware/design issue common to every single unit without exception.

Just noticed some banding

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.
