Many of my friends and classmates carried the S3 in Pebble Blue..
I have the Marble White version
I have realized 3 issues with Pebble Blue models on the ATT/Rogers GS3 i747m
The first one being the OLED screen has some mura stains on it.. I wouldn't really call it stains, it is more like dots... Compare to my PS Vita, the OLED on the GS3 Pebble Blue is much less visible to the eye in a dark environment, and the GS3 mura do not have a lot of "stains", but rather the mura on the GS3 are composed of many darker dots and some bands on the screen.
The second one being the home physical button is colored differently than the dark blue on the rest of the phone. In most lit conditions, the buttons appears Purple rather than dark blue, and yes, I know it happens to the GS3 International as well since people reported it.
The last issue I have see is the button backlight for the MENU and the BACK capacitive buttons. If viewed in a dark environment or a dark room, I can see that the right side of the MENU button is dimmer than the right side of the MENU button, and the right side of the BACK button is dimmer than the left side of the BACK button.. This means the buttons have the LED backlight around the HOME key area..
On my White GS3, there is no mura (my S3 from Rogers is manufactured on July of 2012)... This might be I got a good batch... The Pebble Blue version that had the mura was manufactured on June of 2012, and it might have been a bad batch...
The physical button for HOME is the same color as the rest of the phone's housing... But of course, with the white version you are sacrificing the "imitation brushed aluminum" finish...
Also the backlight for the MENU and BACK buttons are much much more lit up evenly.. <<<< This is probably due to the white color glass and white LED and it is more translucent... ****NOTE: Because of the translucency, the LED notification light (R, G, B colors) appears to have a glowing halo around it when it lights up. You DO NOT SEE THE HALO ON THE PEBBLE BLUE VERSION.. On the Pebble Blue version, the LED is seen as a circular shape with a sharper edge.. On the Marble White, the LED is seen as a circular pe with blurred edge, kinda like an out of focused light source (Bokeh) in photography....
Anyone out there with a White color or Blue color that has issues with OLED mura/stain/dots/bands when it displays a completely black image and viewed in a dark room?
I always just assumed the home button was purple on mine xD
Mine's purple. I like purple so It's fine.
My issue is with wifi and it's different than the drop reconnect issue most are having. I know Samsung has notoriously weak wifi antennas but I should at least be able to leave the room my router is in and maintain signal. I can't. I also can't use hotspots in most public places because the signal is just too weak for my phone to pick up.
I'm going to be getting a warranty replacement when I get back from vacation in a couple of weeks because I need my phone until then.
My s2 had a single splotch / sorta blurry part on its screen sorta looked like water damage? ( is that the mura people speak of)
My white s3 is pristine and perfect in every way I was very happ about that. Checked the screen before I ever even left the store.
Well Samsung is not really notorious for the WiFi antennas..
My Samsung Captivate (Galaxy S) has very good WiFi signal even in the basement.. In the public space, I could pick up numerous WiFi signals....But on my GS3, yes indeed, the WiFi is EXTREMELY WEAK.
I have to literally be in the same room as the wireless routers to get around 2-3 bars.. I have to be 10-20cm from the router to get a full signal WiFi connection...
Read my WiFi thread:
http://forum.xda-developers.com/showthread.php?t=1794927
From my other WiFi thread, some people are reporting that they exchanged the phone and the WiFi is excellent... I do not believe this is the case though since I have exchanged my phone a day or two ago, and the WiFi is still weak, but at least it does not randomly disconnect like my old defective unit...

Hi there,
I just got my T-Mobile SGS2. When I look straight at the phone screen, I see whites that are yellowish, as if the color temperature is bumped up by +2000-3000K. Tilting the phone 5-10 degrees to the left or right shows proper, much colder whites, as one would expect. The same nice whites can be seen if I tilt 20-30 degrees up/down.
Perhaps I would not have noticed this problem had I not played the with international version of SGS2 - the whites on that phone are just stunning anyway you look at it. I went back to the T-Mobile store and all the SGS2 phones there the same "issue". The guy in the store thinks that is how the colors should be...
Am I going crazy here? Is it normal to see this yellow cast with a straight viewing angle? Can someone confirm that their screen shows fine whites at any viewing angle? I'm considering sending the phone back for replacement, but it'd be futile if this slight yellow cast is indeed normal...
Mine is like that too. I think its just a quality of the amoled screen, cause I've seen it on other amoled phones too. You get used to it.

I've checked out/toyed around with close to half a dozen handsets since they came out a couple weeks back and I have yet to see one that has a yellow tint. Every one I've seen has had a blue hue/tint, some approaching a grey cast while a couple others almost like a light mint green. Unfortunately AMOLED screens have the hardest time reproducing white as there apparently is no such thing as a true white LED.
Sounds like the one you got did indeed come a lot warmer than most which tend to me on the cooler side. I wish they would have a factory setting much like most flat panel TVs have for setting/adjusting color temperature to your liking. The blue tint really bugs me but I guess over time you just get used to it. Same would go with yellow too, just have to get used to it. I suppose you could keep exchanging phones as some lucky few out there seem to have gotten handsets with a good color temperature where whites actually look white, but who knows how many times you'd have to try that. I'd bet most places wouldn't be too willing to do that for a customer though.
I'm looking at a yellowish tinted XDA now. Totally dark in my room, auto backlight could be the issue...

Hi,
I got a grey One X last week and while fairly happy with the phone I thought the notification LED was pretty dim. Unless I look at the phone flat on I can't see it is on. I accepted this was to do with the LED being placed within the speaker grill; however a friend got a White version a few days later and the LED on his is about 3 times brighter.
A few videos I have seen show the Grey phone has a very dim light, would post them but can't link unfortunately.

I think that is simply because with the white casing, the light is able to shine through the white casing itself. Whereas obviously with the darker casing, it is truly confined to the tiny little hole of the earpiece. I do get the feeling that HTC designed the white one first
Yeah maybe, but comparing the two side by side, it looks as though his LED is a different type entirely. Looking at the LED straight on should negate the case colour and in that scenario his white version is still far brighter.
As long as other people think the grey one is dim there is no reason to send mine back.

It was one of the first things I noticed when I held a grey one. So I don't think it is faulty. But just like most things, LEDs do vary from unit to unit in brightness.
i haven't seen a grey one, but with my 2nd white replacement, the charging led was stupidly dim. now im on the 3rd replacement, the same led is much much brighter. leads me to believe it was positioned incorrectly, or just a crap led.
quality control really sucks atm.
I'm now on my 3rd unlocked European One X for one reason or another - the white one's LED was just right - I could clearly see from a distance if it was charging or flashing. The two grey ones I've had both had barely visible LEDs, which I can't see when the phone isn't right in front of me or when it's at an angle. Is this a problem with some of the phones in gereral or is it just an issue with the grey model? Cheers.
Your 2 grey phones may have been defective, but in general white surfaces reflect more light than black/grey surfaces. This could have made it appear as though the lights were of differing brightnesses, or just that the white phone reflects more of the led's light.

My grey one is just the same regarding the LED, it's a pixel sized flash as it is shining through one of the "precision" drilled ear speaker holes, so you have to be almost looking directly down on it to see it, certainly in normal lighting conditions.
I expect the white is just a bit more translucent so you see a bigger area of light.
It is one of those silly design decisions that HTC seem to make sometimes! The LED should be behind the glass at the top right where the border is, in the same way the other sits the light sensor. I've always assumed it was last minute rushed job to add an LED, and as after thought they just had to place it where they could that didn't mean reworking the phones design.
Some phones don't have LEDs at all. I'm not sure why a notification LED has fallen out of fashion, I find it really useful, for example I leave my desk to make a drink or see someone or for a comfort break, then arrive back to my desk, a quick look down at my phone I know nothing arrived while I was away and it saves turning the screen on to check.
Regards
Phil

It must be a defect which happens to be on the 2 grey phones then because the difference is huge - one is barely visible and the other I can easily see from across the room (it's probably 30 or so times brighter). Hopefully my 4th One X, which is on its way, will be ok (the white one with the good LED has the wifi problem so that's going back).
I just bought one of these as a birthday gift for my, once I opened and tested tablet, I immediately noticed purple fringing everywhere specially on white letters. Actually it is weird because:
1. On normal view, that is the Hardware button on the bottom, the purple fringe is noticable at the top of every letter, and "GREEN" fringing at the bottom of every letter.
2. When i rotate the tablet 180 degrees, (screen autorotation is on) that is the Home button now is at the top, I nptice the purple fringing is at the bottom, and the green fringing is at the top.
Anyone also noticed this on their Tab S 10.5? I am now regretting buying this.
===========
Edit:
I forgot to mention, with normal web browsing, there is no problem. The problem can only be seen when looking at the icons and their description, and also when you go to settings, it can be seen on the letters there.
I have just been to my local walmart and tested their machines there. Their unit has the same purple fringe on top of icons, and green fringe at the bottom of icons. My guess is my eyes are faulty, or my eyes are well trained to look at Samsung screens and look for faults. Super Amoleds are really not yet perfect.

I have had nothing short of spectacular graphics/images on my 10.5" Tab S and can't see even a hint of fringing. I wonder if anybody else has had this problem. Would it be possible to exchange your tablet, because that doesn't sound normal to me? I've seen 3 or 4 10.5" Tab S' s and none of them displayed the fringing your experiencing. Good luck!

Your tablet is defective. Return it.
I have just been to my local walmart and tried their machines there, they have the same fault (or should I say "characteristic) as my Tab S...
I have updated the op...
I am still waiting for other people for their feedback before I return mine to amazon. Problem is, this is a birthday gift, and it wouldn't came on time if I return it and have it replaced. My walmart only has the black one.
No need to regret a purchase just because you happen to aquire a defective unit. If the store units are exhibiting the same characteristics then they have a bad batch. My screens good apart from a very slight yellow cast when viewed head on, but it doesn't really bother me, besides all stock is sold out where I live and I couldn't get a quick replacement anyway (I'm off on holiday next week and need a tab!)

The black one? Tab S does not come in black.
Colors on a properly functioning Tab S should be perfect. Whites white (with no yellow tinge) and blacks black (with no mura effect). It has been well documented that Samsung let some mad cows out of the barn on this one. If your screen is demonstrating any of these defects return it (the same store likely has more defective units from same run).

I guess you already know what i mean when i said black... I meant titanium bronze.
Anyway i have already packed the tablet and will be returning it.
I don't know the extent of the fringing problem on your tablet but I can add this to the conversation. There is a slight tint to the screen depending on which way you tilt your device. Its an AMOLED display so its inherent.

You seem to be extremely sensitive. Do you even notice it from a distance, or do you have to get really close to the screen to notice it ?
It could be related to the screen's subpixels layout, here it what it looks like when zoomed it: http://cdn.gsmarena.com/vv/reviewsimg/samsung-galaxy-tab-s-105/samsung-galaxy-tab-s-105.jpg
You may want to have a look at it with a magnifiying glass, I wouldn't be surprise that this layout is causing your issue.

I'm not sure about tab S 10.5, but 8.4 is affected by Mura effect. Not on black though, but only on extremely dark colors.
"It should be white viewed directly and slightly pink at am angle."
Amusing, on 8.4 the tint is green when viewed at an angle, not pink. Same goes for my Galaxy S2. It looks like some greenish transparent liquid was painted on the pannel. I always wondered what it could be, as it seems to be specific to Amoled.
Bump: Just purchased a Samsung Tab S2 and have a similar purple fringing issue and slight text aliasing. Mostly occurs with black text on white background.
I took a few macro photos that display the issue. As I just registered to discuss this issue I am not allowed to embed photos from imgur, to view remove the space between imgur and .com.

Hey everyone,
I got my black AT&T Note 4 earlier today. I noticed the lower half of the screen is slightly darker, and has a slight pinkish tint on a white screen.
I do notice it in some apps, like Kindle when readinga book. Top of screen is slightly brighter, and when background is white there's a very slight pink tint.
Is that normal? Or should brightness be uniform and no tint?
EDIT: I added a photo. It's not a good photo but you can see how one side is tinted differently. In the photo the brighter top looks greenish but in real life it's not green. You can also the slight pinkish tint in the bottom half, which is the left side of the photo.
I wouldn't want to comment based on the image you uploaded directly since how a camera captures a digital display is much different than what the naked eye will see. If the picture on the panel is not consistent and appears polarized in any way, I would consider that to be faulty. Get it replaced.
Galaxy Note 4 (pink tint lower screen)
Hi there,
I have also noticed a pink tint on the lower half of the screen on new Samsung Galaxy Note 4.
As i intend to do a lot of drawing on this device the tint is unacceptable.
I wonder if there is a way to calibrate the display?
I had this issue with my Galaxy S3 display. I had at&t exchange it.
Have this same issue on my Note 4. Posted some pics over in the thread on this topic for the Note 3 before I thought to check here. Basically there's a brightness and gamma gradient from top to bottom. The top half is perfect and the bottom half gradually fades to a point where you lose the first 8-9 squares on the lagom.nl black level test.
This one emphasizes the black crush, which can be visible in video content on a dark screen (and makes dark colored backgrounds fade to black towards the bottom):
And here's one on a white background. At first it seems like a white point issue (which I would tolerate since it's common on IPS as well), but it's a brightness gradient:
Between this and the fact that AT&T disabled the slider for auto brightness I'm a little frustrated with this supposed best smartphone display ever (I realize this second issue isn't Samsung's fault, but the auto brightness is unusable without that feature). I bought the phone at Best Buy which is mostly out of stock right now so an exchange isn't likely, assuming they even take this seriously as an issue.
My note 4 does not display this issue.
No issues here. Display looks very consistent.

Have you tried a dark background in a dark room? For me it wasn't that obvious until I did this (was messing around in Sketchbook). If the majority of screens are better than mine I'll definitely be trying to get a replacement as this is bothering me.
I just installed Lux to resolve my backlight issue and its settings menu background fades nearly entirely to black at the bottom.
*Edit: So far it sounds like this is an anomaly. You would expect places like Anandtech to report on it if they'd seen that amount of variation. I'm going to have a good time trying to convince someone at BB that this is a real defect though.
Erica Griffin talks about this issue in her Note 4 review, around the 20 min mark: https://www.youtube.com/watch?v=-OyNWrQJzMY
I got a replacement and it's perfect. No pink tint.
So, if you have the tint return it. Not all Note 4s are like that.

Thanks, that was quite helpful. I think in general it's easier to trust reviews on retail-purchased devices over mainstream reviews with PR department selected units.
I went to BB today and looked at the display units. All perfect, but then that's not surprising (every company gives their display/review units a second QC pass, even Apple). I'll probably head to the only BB in the area that has units tomorrow and see if I can do an exchange. As long as they don't make me sign one of those "no more returns" agreements I've heard about I'm willing to take another shot in the display lottery.

Good to hear! I'll post my results after my exchange attempt tomorrow. Aside from the gradient I am impressed with the display. Not as bright as LCD in daylight, but I was drawing on a black BG last night and noticed that it has deeper blacks than my Pioneer plasma.

Fingers crossed for you to get a nice one like mine.
Yeah, the blacks and colors are amazing on the Note 4. The whites are not as bright as the iPhone 6+, but they are fine and way better than whites on my Note 2. In all other respects the Note 4 screen is overall better than even iPhone 6+'s excellent LCD.
One minor disappointment is the very high resolution has made some emulators dog slow as they attempt to render at full resolution, i.e. PPSSPP and ePSXe using ogle renderer. Hoping the devs find a workaround, maybe rendering at half or quarter rest instead - that would still be higher rest than my Note 2 at full rest. :laugh:
What's the color of your device? Anyone have this problem in the white version?
my note 4 has pink tint
I have the same problem on my Verizon white note 4 but on top half of display. Replacement should arrive by Friday :/
You can replicate this by looking at the screen at an extreme angle, obviously the ones that see green and purple straight on are screen defects.
I have a white version and whites are perfect and too bright at high setting. I keep mine half way. The whites are better IMHO than the iphones. The colors more vibrant and, the sharpness is ridiculously sharp. I dont see how they can improve it. I only thing there should be a waynto adjust the color saturation, because basic mode doesnt do much on mine.
My Note 4 has the same issue. It almost looks like the while balance differs from top to bottom, but it is really the brightness that is different.
This is a photo of my Note 4 showing a solid colored image at #030303 (very close to black). It shows how different the pixels in the bottom and in the top emit light.

Looks like crap.

I have a similar issue, though mine is brighter on the right side than it is on the left. Very noticeable with dark background in lower light situations as someone else mentioned.
