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?

Recently i've been noticing a certain color fade on my nexus one. it struck me especially when using handcent, and it's also very clearly coming forward in 3 banana.
Basically i notice that on the side of the screen the black is much deeper dark/black (& 'higher standard'), in comparison to the center. the color depth (again, only speaking for the black standard) is much less towards the center.
It's not really blurring the letters, more fading them into the background color, diminishing the contrast.
Does anyone else have a comparable problem or noticed any kind of similar screen behaviour?
i dont notice anything

the diagnosing powers of the nexus one! what a phone.
In conjunction to the post, "blue tint problem," which isn't really a problem but anyway....
I thought it'd be interesting to create a poll to see where everyone's at with their Vibrants.
Please participate in the poll, it'll be very interesting to see...
So if you're on the blue side or yellow side, obviously submit yours accordingly, however, for neutral that's for those who have calibrated monitors that can get true comparisons to determine if it's neutral.
There's no need to lie here LOL..it's just for fun so the more accurate it is the better. Don't just click neutral if you don't really know for sure. Try comparing your phone first with other Vibrants to be sure.
Here we go!
It's slight blue, but related to viewing angle and screen brightness. Viewing straight on, it's pretty neutral.

I know what you mean. Could the SAMOLED screen perhaps slightly change in its color tone as it warms up?
When I fired up the two Vibrants I have that was turned on for the first time and compared it to my other two which has been in use, the two never been used phones screen looked identical in its tone/shade.
So perhaps over time it does change as it, "breaks in?"
Does anyone know if this blue tint will get better with time? Mine seems to be the same, wondering if I should exchange my phone.
Well, mine is more cyan, though I can understand people calling it blue and it's driving me crazy. Even with brightness all the way up, there is no real white. This issue will likely cause me to return my Vibrant - along with the cheap build quality - as my Nexus screen looks much better and neutral in comparison. Even my wife noticed it immediately though she also has a Nexus.
Neutral, I've compared with monitors and other Vibrants from my T-Mobile store.
The blue should fade over time..sometimes they put in a bit of extra blue to compensate the blue's lower life span..if you want to even it out use a blue background as your home screen for a while and it should even out >.>

When compared to mine my wife's had a very strong blue tint to it. Since I ordered ours over the phone I called Tmobile. They overnighted me a replacement without any hassle, I'd give them a call and see what they will do for you.
posted this in the other "blue tint" thread too
"...since the OLED material used to produce blue light degrades significantly more rapidly than the materials that produce other colors, blue light output will decrease relative to the other colors of light...In order to delay the problem, manufacturers bias the colour balance towards blue so that the display initially has an artificially blue tint, leading to complaints of artificial-looking, over-saturated colors..."

I guess if you did not receive a defective Vibrant with an extremely blue screen, even with brightness all the way up and power saving mode off, your not qualified to speak for those who did. Of course it would not make sense to you.
i dont know about you guys but every time Ive ever seen a white LED its always had a blueish tint (like automotive LED's) its really not that big of an issue
My display was noticeably blue the moment I turned it on... going to the T-Mobile store today to see if I can get a better unit with a more neutral color temperature.

It matters to some people more than others. If it doesn't bother you then great. It's not really fair to criticize people who are bothered by it--one should have a reasonable expectation for color accuracy of their display, especially for a device so touted as being a multimedia powerhouse.

You know, some people here say every Super Amoled has a blue tint. I have to disagree. I've been comparing my vibrant side by side to other vibrants, and the screens vary from phone to phone. Samsung deffinately has some manufacturing inconsistences. Side by side to other Vibrants, my screen has a very visible dark grayish blue tint. Other vibrants have a slight blue/green tint. While other vibrants i've compared to have gorgeus warm whites. 1 vibrant had a very dingy yellow look to all the whites. So this is not in our imagination, the screens vary a lot on these phones.
My cousin just got the vibrant this morning, she had not seen mine. She saw mine this morning and says "why is your screen blue?" Put mine side by side next to hers, and hers has nice warm bright whites. All of our brightness settings were identical.
I'll be exchanging shortly when I have time.

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.

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.
The Galaxy S2 is known to consist of many issues particularly with its screen. Although the screen technology is far more superior than the one featured on the Galaxy Note, I wanted to know if the Note has any of the following issues with its Super AMOLED HD screen--
1). Black blotches? (*#0*# Select Black; wait for your eyes to adjust; be in a complete dark setting, and assess for this)
2). Stains? (*#0*# Select Black; wait for your eyes to adjust; be in a complete dark setting, and assess for this)
3). Red Tint in Black Background? (*#0*# Select Black; wait for your eyes to adjust; be in a complete dark setting, and assess for this)
4). White-colored bleeding? (*#0*# Select Black; wait for your eyes to adjust; be in a complete dark setting, and assess for this)
5). Brightness uniformity issue? (One side darker than the other or lighter than the other, vice versa)
6). Color uniformity issue?
7). Washed out colors?
8). Lack of clarity?
9). Horizontal or Vertical lines?
10). Ghosting?
11). Circular mark?
12). Banding? (Use *#0*# to test)
13). Dead pixels? (Use *#0*# and Select White)
Above, are issues I've encountered on different S2's. Please let me know if you spot any of the above issues on your Samsung Galaxy NOTE. I really want to gather feedback on all of the above. Thank you.
I dont see any of the above issues but one issue is the white seems little bluish due to pentile matrix

Bluish-tint is normal for Pentile matrix, but is the color evenly distributed?
? I haven't encountered any of the issues that you mentioned on my SGS2, and I've had it for almost 1/2 year now.
Anyways, just picked up the Note a few days ago and still customising to my liking, but so far have noticed (compared to the SGS2):
1. Banding. It's more noticeable (eg. Grey keyboard keys) compared to the SGS2.
2. Tile pattern when seeing grey background (eg. The notification bar)

Comparing to my S2, the screen is brighter at 100%, I can read better any text, but I can still see the pentile screen. Not much problem, it is not annoying as hell as was in the first galaxy, but it is there and I can't wait to note 2 with plus technology.
So, on your questions, no to all of them.
Oh, for banding, testing with this image

I can't see banding when I use full screen view on browser, but it is there if you move the image or don't see in full screent. It looks like the stock browser changes the colour to 65k when you make scrolls or something like that to be faster and smoother.
No problem for me.

Don't panic. The screen on mine is superb.
I have not looked at any lo-qual 8 or 16 bit images, which will look like so called "banding". Banding is not a technical term, but I know what you mean.
This screen is 24bit, Millions of colors. If you look at 8-16 bit images, they will show banding. On older devices, you would see nothing but banding as they were only 16bit max.
Check out this: color depth
The checkerboard pattern happens when the screen redraws graphics when you resize it.
Zooming out to see a smaller view of a web page, there is a momentary checkerboard pattern behind the image, like the pattern denoting a transparent background in Photoshop. Normal and nothing to worry about. When I think about it, my HD2 showed a blank white background in this situation, not as good as I could not distinguish a page being redrawn and a web connection error giving me a blank page.
Samsung are leaders in the field of screen technology, no? Think about it. Who makes the best TV's? OLED screens are now becoming the TV industry choice of video monitors. They often cost over $10,000. Broadcast engineers are not likely to accept lower grade technology. In fact, LCD's are on the way out.
Don't believe the hype.
This device is amazing.
You can also use *#0*# to assess for banding, although I would believe banding to be common on a phone with greater resolution. The Galaxy S didn't have banding btw, unsure if that had to do with smaller resolution.

I wish I wont have a problem.
I saw an interesting issue with 2 G2 Phones when I went to upgrade today and I wanted to see if others saw the same artifacts.
1.) When holding the screen under bright light, it looks like you can see "through" something and it appears like you can see a pattern of some sort either on the LCD itself or maybe some sort of polarizer. If this was the only thing I noticed it wouldn't have been an issue.
2.) When on a dark or black screen, you can see vertical "stripes" of dotted white lines. This was the deal breaker for me. I purchased the upgrade, they handed it to me and all I could see were these vertical stripes of white dots across the screen.
The other G2 did this as well. Were these a bad batch of G2s? Is this some sort of artifact of the IPS screen? I was coming from a Droid HD which had nothing of the sort but it isn't nearly as high resolution of a screen.
I ended up with a Note 3 because of this. It wasn't my first choice, but there was no way I could look at those stripes for 2 years!
Are any others seeing this artifact on the screen?
Thanks!
It's the digitizer. All G2's are that way I believe. Not a defect. Some phones you can just see it more than others.
OP let me get this straight, you don't like the phone because of the dot matrix you see when the phone is off and in direct sunlight?

It's when the screen is BLACK or DARK while the screen is on. I think whomever suggested the digitizer is probably right.
One of the artifacts didn't really bother me, I was more so fascinated by the pattern than anything else. To see that one the light had to be intense and direct (screen on or off) so very low likelihood of that impacting day to day use.
The artifact that really bothered me was, for lack of a better explanation, the white dots on the screen that looked like backlight bleeding through tiny vertical perforations in the LCD panel. I'm sure that's not actually what it was, but that's what it looked like to me. I'll probably end up with a G2 in addition to the Note, but I wanted to know if the ones I looked at were part of a defective batch or not.
Thanks
