Everyone talks about the screen smearing (purple/pink tint) but nobody talks about how the there are ghostings (leaves a trail when scrolling) which is especially profound in text. Is this normal?
That's what smearing is, leaving purple trail - it's not ghost images. Ghost images is what you get after using it for a long time. Isn't the smearing what you're referring to?

I haven't come across anyone else talking about this... lately, I've been noticing that the screen on my Epic seems to have some sort of issue displaying grays/tans/off-whites, and I can see darkish streaks on any image that has those sort of colors.
A perfect example of this is the Tweetdeck app's gray background. I have already traded in for a new Epic from Best Buy because the screen had really obvious darkening that shouldn't be there on the left side of the screen when I used that app, and I thought it was just a bum phone.
But with this new one, I've recently noticed the same sort of streaking (no big spots like before though, just thin lines).
What's really strange is that it almost looks like it is something UNDER the screen, not an issue with the SAMOLED screen, but it only happens on those colors, so maybe it is.
I'm still going through the process of deciding if this is enough to bring it back again (it obviously doesn't hurt functionality), but has anyone else experienced this?
If you're displaying a non-constant grayish background, positioning of the pixels in the PenTile matrix can produce unexpected patterns and even colors (the N1 could hbe coaxed into displaying a rainbow with just using white and black pixels strategically arranged.) On a steady background though, it shouldn't be a problem.

So this is just the nature of the device's screen matrix? Would the PenTile matrix's "unexpected pattern" be unique to each device? Cause it always looks the same when it comes through, as it was with the massive darkening on my old Epic.
I have to say I can sort of see it even on solid gray screens (via the Dead Pixel Detect app), but it definitely is one of those "I'm really looking for it" sort of situations. I'm not looking at solid gray screens with NOTHING on it all that often.
I thought I was the only one. My second phone had it bad so I traded it in for a new one. This one seems to have it as well but not as bad. I notice it most on greys like when I pull the notification trey down. It is most apparent on the lowest brightness setting and solid colors.

I too am having this issue, and like you all, it only shows up on grayish backgrounds or the like. Is there any remedy for it? It's only a minor annoyance...
Perhaps one of you who is experiencing this can take a macro close-up and post it? You should have no irregularities on plain gray backgrounds.

The only camera I have at the moment is the Epic, but I'll see what I can do tomorrow.
It looks like I may be returning this one regardless... the screen on the left side is starting to lift out of the plastic bezel.
I'm also having this issue with my screen. It's pretty annoying. Does anyone know if there a fix for this or is it a pure hardware issue?

Hi all,
I know there is alot of discussions surrounding yellow tinting and yellow colors , or uneven screens on S2 , S3.
But I haven't seen much of it talked about for the S4.
My S4 has slightly darker colors on the top of the phone. The difference is quite visible on a white background, and very visible on a grey background.
Here some photos showing the issue:
From the naked eye the differences are not as great as shown on the photos. however it is there. sometimes its darker sometimes its not so much darker. but visible and very evident that the screen colors are not even.
Is there any problem with this? Do I need to take it to Samsung for repair?
When I'm using google for example the top of the screen is like bluish....and the other half of the screen is white.
Because I haven't seen many discuss about this issue, I'm wondering whether its just mine?
You have a defective screen.
Take it back for repair or replacement
Yo.
I'm still wondering if my S5 screens is as good as it's supposed to be. I have 2 major concerns, screen uniformity and purple trails.
I come from an ancient S1, and nothing of this happened. I have attached a single color pic that shows clearly how screen have a soft gradient from top to bottom on my phone. When I put basic colors (RGBYWB from test modes or apps) nothing of this is apparent at all, and screen looks gorgeus, but this color and some other grays show what I'm talking about. I would be grateful if you load the pic in full screen mode and tell your impressions. Offscreen shots would be welcome too.
Also, about the purple trails when moving on screen pitch blacks, it affects every screen or only some unfortunate ones? S1 never show anything similar. Max bright reduces it, but nor completly.
Greetings.
It's come to my attention that some people may not have tinted displays but have horizontal screen banding.
This is not normal, and no, it is not a properly of AMOLED screens. It is not image retention. It is a defect. It is especially visible on grey backgrounds.
You can check for yourself by downloading "Dead Pixel Test" by Ossibus Software on the Play store. When viewing the darker shade of grey, if your screen has banding, it'll be clearly visible as horizontal line(s).
Has anyone experienced anything similar?
*Raises hand!

Both are Nexus 6P. Guess which one is going back for replacement.
For some reason it shows up better the farther away you are... in person it is fairly obvious.

Here is my post from the "pink hue" thread, most appropriate here. It shows an example of what to look for.
(Ignore the diagonal lines. Those are scanline artifacts of a CMOS camera sensor.)
The thumbnails/looking from a distance/in person it is far more evident. Especially on movies/images with gradients. The human eye is remarkably sensitive to contrast.
You shouldn't have to hold a phone 5" or closer from your face to not notice abnormalities. If you have to, it's a defect. That's my reasoning, anyway.
Also, this is a "minor" defect, but a very noticeable one.
It's like a watermark, or bright spot on the display, and can be very distracting during daily use.
It draws your eye's attention to one region of the screen, regardless of content there. (Text, etc -- lower 1/3, in this case, gets focus.)
This criticism is especially true because this is an "ultra flagship" device.
(I didn't spend $900 on my first car, let alone my first phone.)
It's really looking like Samsung sent the defective screens that were in the garbage to huawei from all these threads I'm seeing on the screen.
I'm not sure if I'm the only one, but when I browse Reddit Sync on AMOLED mode on a decent brightness, I get minor to severe ghosting on certain images. Its gets worse on lower brightnesses, and I'm not sure if this is common occurrence for AMOLED screens, or if I'm the only one. Thanks in advance.
Link a page you're getting ghosting on so we can test it, also tell us what brightness setting.
I get screen ghosting when the color changes from pure black to grey. Especially when scrolling a black object on a grey background, I can observe the back pixel takes some time to switch to grey.

I get it as well, I think it's just a limitation of AMOLED panels. Not sure if the newest (on the Galaxy S7) have it as well but it happens with a lot of AMOLED panels.
