Off-Color Screen Streaking?

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?

IMPORTANT: Screen

So can anyone confirm that the striations or lines on the screen are normal??
Im talking about when you pull down the notifications bar there are light lines that come down vertically and soma cases are horizontal.
Please let me know I got 30 days with it. thanks!

my first nexus s had darker whites than the display model at the store. I would recommend comparing yours with the store display or another persons nexus s, I think this is the best way, since we cant physically see how your phone screen looks. good luck

Are you referring to the gray section where your service provider is listed? Or the very dark area where the notifications are listed?
If I stare I can see some lines in the gray area.
I do see a slight grid pattern in the power control widget.

No I'm talking about grey section where your messages show up

I think its screen burn in already

I don't have a Nexus S, but I have a Galaxy S i9000M which has a similar (if not exactly the same) screen. If I bring up a screen that is a solid colour, I do notice some imperfections like you describe. They are hardly noticeable though.

Weird. My nexus doesn't have that and I would know, I modded my nexus 1 to be pretty much like gingerbread 6 months back, massive burn in.
Sent from my Nexus S using XDA App

actually no.... mine doesn't have any lines or defects.
the only lines are the horizontal ones separating the notifications.

I think I know what you mean. My N1 on certain backgrounds has very faint grey lines. Not always visible, even on white web pages

Why would that cause burn in more than anything else?

Yes, I can see it. I can see it on any AMOLED/SAMOLED phone I've ever come in contact with. It's the nature of AMOLED screens unlike most LCD screens. With AMOLED, each pixel is individually powered, and it's impossible to have each pixel (or subpixel) be identical, which leads to slight differences in output and color reproduction. An LCD screen is backlight by either florescent tubes or recently, LEDs, which produce an even backlight (usually) where the colors are controlled by filtering each pixel, rather than having to illuminate each pixel.
Anyway, I only really notice it when the brightness is at the minimum and it's very dark in the place I'm using my phone. If I crank up the brightness or if I'm in a well lit area, I don't notice it at all really. Although if it's VERY obvious, you might have a screen that's significantly lower quality than average... it happens, bad QC or something, exchange it.
Oh, and if you stare at a plasma TV long enough you'll notice the same thing... similar technology, each pixel illuminated individually.

Is it true - Grey color and super amoled don't go together?

I recently purchased galaxy note and had dead pixel issue with it. So I got it replaced, and now the second one I ve got has this strange light greyish blemish visible on grey backgrounds. Also when I see the screen with grey color on it the screen doesn`t look uniform where as in all rest of the colors it looks uniform. Please have a look at the attached pictures and let me know if its normal ?
Also please set your brightness to 15% or below to check your devices.
Heres the video for better view:

Honestly, I don't see any blemishes at all. However, I do see a lot of air bubbles trapped under a screen protector. Are you using one?

Yes I am using a screen protector with lots of bubbles. But do check out the video, in images its not much visible !

No issues on my Note
No issues with the screen, no grey spots no bubbles, no screen protector.
My screen is great.

Also please set your brightness to 15% or below to check.

My god that CPU is loud!
Btw, i can't see anything.

Same thing happened to me. The 1st note I got had dead pixels and dust moving behind the screen. The second one had those dark lines on grey and white color... the first one had those too but not as much as the second one. I sent them both back for a refund. Don't know if I should try my luck on a third one..
Here are some photos:

[Q] Note 3 N 9005 16Gb version: The back light of the screen can bee seen!

Well, I actually noticed it with my Samsung Galaxy Note 3 16Gb N 9005 version.
When I go into settings and open "Accounts" or when I hold the home button to see apps running, I can see the back light on the lower half of the screen. Well, I can see the back lights because the background is black. Whether I'm using it the screen with 100% brightness or less possible, it's the same.
However, when I'm viewing dark pictures or gallery or many other parts that has a black or dark background I can't see the back light. Unfortunately I don't have a picture of it cause I don't own any other camera than my phone to show it to you.
Well, I just wanted to know if it's actually normal to see the back light on the screen as I explained above or is it that my device is a defect one or is there some sort of setting that can change it.
My friend has the N9000 but I can't see the back light on his screen. I'm a little worried.
Thank you in advance for your replies and help!

I've got the 16GB N9005 as well. The screen doesn't have perfectly dark blacks.

Correct. I was under the impression this was unavoidable as it is the lcd reflecting the backlight.
Maybe I didn't understand your question.

I hope it can just be fixed with an update!

Does the 16gb version have an lcd panel ?

You have a defective screen.
AMOLED displays don't even have a backlight, individual pixels themselves lightup when needed and go off when it's black.
Unless the 16GB version has an LCD display - which I am not aware of.

16GB? Really?

Well, I don't know if it's the back light actually. However when I go into settings and then account on the lower half of the screen, I can see the white lights behind the screen. It also apply when I hold the home button to see active apps I can see the same white light like on the lower half of the screen. Normally, since the default background is in black or dark grey it is noticeable.However, the weird part is when I go into gallery which also has the black background, it doesn't appear there! It's full black and I don't see the white like stuff.
Normally it is more visible when I'm in a dark room, mostly at night!
It's not LCD, it's Super Amoled just like the other!

yellow screen?

Is this normal or do I have a faulty unit?
Screen looks very yellow compared to my other phones.

What is the other phone? Go to settings -> display -> color mode and set color to normal, that will normalize it a little. It's set on vibrant by default. Regardless of that setting though, the screen on this phone is a "warm" one compared to others. The phone on the left is "cold" and bluish in comparison. Warm screens are a little more yellow/red, cold are blue. If the other phone is AMOLED there's your reason, but even if it's LCD, it's just tuned a bit differently. You should know that the phone on the left isn't producing a perfect white either, just a kind of white you're used to. Personally I prefer a warm screen, I find colder screens harder on my eyes.
TLDR- it's working as intended.

Unless you screwed with some settings no that isn't normal. If my whites were that yellow I'd return it. While an LCD might never be as white or black as an amoled it shouldn't look like 20 year old yellow paper either. WIth LCDs if you lower the brightness the screen will become more colored but nothing like that. You can also go compare it to some phones at the store that have LCD's and get an idea if its out of whack.

I spoke to two different support people at motorola ...one said it was normal for this phone as the screen was optimized for gaming?? .....the other said it was not normal and I should return it.
I tried using the app 'screen adjuster' to boost the blue light and it did indeed make it look white rather than yellow so it seems to be a color temperature setting so I'm still not sure wether changing the phone would make any difference and I can't compare in stores because they don't have them yet.
p.s. the other phone is an LG G2 which is LCD

Mine seems to have a little yellow at low screen brightness but it doesn't seem as bad as in your photo. I probably would not have noticed if not for this thread. Is your screen brightness low? Mine gets more white as the brightness goes up.

If it bothers you you can go through the return process and see if another one is different. My phone looks pretty much the same next to my Galaxy Note n-7000. That's AMOLED, but AMOLED or not, screens can be bluish. For perspective, here's what white looks like for reference. Neither of the phones are producing white. One is bluish, one is yellowish. Do you notice it when you're not comparing phone screens? After a few minutes of looking at the screen, going from app to app or looking at pictures, do white things register as white?

I noticed it had a very warm color temp immediately I turned it on, and then got my other phones to compare ....it does bother me yes ...it's like having a TV with a yellowish screen ....I'm pretty sure it can be fixed with a software update and is not a hardware problem which is why I'm not sure if returning the phone would accomplish anything unless I see some other pures to compare
I just found this thread on another forum:

I also noticed that the Moto X screen runs a little warm with regard to color temperature. When browsing the web via Chrome, there’s a noticeable yellow tinge, especially when compared with the iPhone 6 Plus’ screen.

This is mine. I think ambient light may affect it. It looked more yellow when I was in a dark room. This is in a well lit area.

Mine is warmer color from 50% to 0%, Higher values and its very white. Didn't even notice it till I saw this post and well, it can't be unseen lol. I keep my display around 10-20% usually on the low side however at night in bed it doesn't look warm at all.

yeah, ok so it seems it is quite normal for this phone then, although from the androidcentral forum thread I posted above some screens are more yellow than others and some are actually very white, seems to depend on the batch .....i guess I'll just learn to love it :laugh:
