Red edges to text

is it just me or does the white text on this screen have red sticking out edges. I think I read somewhere about the pentile matrix causing it. Can someone confirm. It's a shame as the screen is great otherwise. Also when you have a white screen, it's got a green line on the left and a red on the right.

I can confirm this. I guess it'a downside to amoled screens... Oh well. Nothing is perfect.

None of that for me. Take yours into a store and compare side by side with another to see if yours is faulty.

Actually yes there is a tiny green strip down the left. i hadn't noticed that over the past two weeks!

I guess it is just a downside, but it's a pretty big one considering how samsung bit back at steve jobs fir saying the iphone screen is better. Jobs is right by the way ip4 is much crisper. Strange that none of the reviews would mention about these red things around the text. Every review I've read before buying said this screen was amazing clarity. Ib guess I must have better eyesight than these 40 something tech journalists!

Really? I mean... REALLY, does this bother you? How close do you guys hold the screen up to your eyes? I notice this easily at 6-8 inches but seriously, when do you EVER need to hold it that close?

I am trying to see the red edge you are taking about from the xda app. The texts on this application are white with black background and vice verser.
Trying as hard as I can I couldn't see them. Are you using any screen protector? Are you sure it is not the diffraction from the protector causing this effect?

Maybe because it does? I don't think there's a review that says the SGS screen is superior to the Iphone 4. They both have their positives and negatives. I looked at the ebooks that come with the SGS and I could easily read them without any problems or strain on the eyes.
People here are so picky. This doesn't work, that doesn't look right, they should have done this instead blah blah blah. I'm I using the same phone? cause I'm enjoying mine.

I can't understand why the hell people are going out of their way in such an amazing way to find stuff like this that NOBODY seems to notice even under heavy use.
No one complained about it in the nexus (nor about the green stripe/red stripe)
Yet, if you look for it- IT'S THERE. LIKE ON EVERY GODDAMN AMOLED SCREEN IN THE MARKET.
*This said, i can't see any red "outlines" on white text.

OP, you're too picky. This is probaly the most perfect non-iPhone screen money could buy now. Enjoy it.

If you look VEEEEEEERY closely, you can find a fair share if impurities in the iPhone screen as well. Mostly poor uniformity of back light dispertion (although a LED screen, it's FRAME led, not local dimming)
And some bleeding in bright shades of red.
Plus, the "blacks" are tinted purple.
All those are tpyical for IPS panels, but if you don't look for them under a magnifying glass (like people are doing here with the SGS), it's very unlikely you'll even notice.
Each technology has it's advantages and disadvantages. Currently all reviews agree unanimously- The SAMOLED screen on the SGS and the iPhone 4 retina display are the two best displays out there, without a definite first place between those two.

Listen I know some of you are quick to say I'm complaining and that I'm being too picky, but I'm only reporting what I noticed to be true on my phone. I posted to see if anyone else could see thee same thing. Not once didi mention I can't live with it, but for me I can see it and I'm suprised that in all the review they haven't mentioned about the red halo around entire text, your telling me that s not a fundamental thing? Come on, fir some people being promised the latest and greatest screen this might turn out to be issue.
Just to be clear, apart v ffrom this and a few small software issues,i love this phone, so please no flaming me for digging at the sgs.

red halo around the entire text. sounded like you have a defect on your hand. My Galaxy s have no such problem.

This is a problem with the pentile technology they use in the screen, the screen can't display white on each individual pixel, it needs to blend the colours from two pixels together to create white. This can make text quite jagged and make the white bleed slightly at the edges.
I too am a little surprised this wasn't picked up in review (although trusted reviews did pick this up) but I think this raises an important point, you need to make you're own mind up and not just rely on reviews. You wouldn't normally spend this type of money on anything thing else without using it yourself first, and its mainly the impatient ones who couldn't wait long enough to try it themselves first who then have the complaints, that's the risk you take! ps I didn't try it first, too impatient

It's not a downside to amoled screens, it's a downside to samsung's proprietary pentile matrix. Pentile is not inherent to AMOLED; every other AMOLED manufacturer besides Samsung use normal RGB sub pixels.

Not on the Cowon S9/J3, Zune HD, Sony XE-1, or LG EL9500. I've taken macro pictures of my S9's screen and it is RGB.

Ok, 90% of the amoled screens floating around on the market. happy?
The vast majority of amoled screens use RGBG.

I used "flashlight" application to look for the green & red lines on a white screen. I thought I might have seen the green line, but I couldn't even be sure to be honest, and there almost definitely wasn't a red line.
I looked at the text a little closer than I previously had and I felt I could see red within white text, however I didn't have a "red sticking out edges" problem. In every day use, and I use the screen primarily for reading internet articles and text messaging, I have never seen the colors within white text.

hmm it odd, f I launch the google home page in the browser, I can definitely see a Green line down the right hand side.
I wonder if my screen as some kind of alignment problem. I donlt even have to look that close to see it, it's a one pixel wide line down the left. and if I look to the bottom and right I see red pixels sticking out from the screen.
I realise that Pentile will make text a little jagged, but should it be this obvious?
I mean the clarity of text on this screen is very jagged compared to my Blackstone, even when I look very closely at that.
Logi

This is the best macro my camera can do at 100% crop.
Try taking the same picture and compare if your screen exhibit unacceptable differences, you may have a defective screen on your hand.

I can see what you're talking about, for me it's one green line down the left and a fainter red one down the right. But this is only on a white screen and when I look hard for it from about 10cm away - it's no big deal.

More bright, more tint vs less bright, less tint

Okay, everyone pretty much knows no two SAMOLED screens are the same. I recently bought a second Nexus S (because I kept hearing people say it has "amazing" battery life whereas I was getting nothing better than my Vibrant) and decided to keep my first one (I will return it later) to compare. The second NS definitely has a slightly brighter screen, but it also has a much more apparent purple tint. The first one has a slightly less bright screen but the purple tint is also very minimal, hardly noticeable unless one is looking for it.
Any suggestions on which one I should keep?
P.S. Both phones batteries behave similar so I guess everyone's definition of "amazing" is my definition of poor.

i personally hated the purple tint. if you dont mind the 'unnoticeable unless pointed out' defect, go for the one with the lower brightness. also, check your whites on both phones because mine had a problem displaying true white.

second phone definitely has "purplish" whites.

My personal preference is to have more accurate colors. If the white isn't white, it's not acceptable for me. I'd go for the less bright one, as long as it's bright enough.

Mine has a blue-ish tint when it's white... really annoying. Also there's banding when I swipe down the notification bar (the dark grey background... lots of odd colored lines). That and my oleophobic coating is wearing off, gonna exchange in a few days. I really hope I get one with a warmer tint so the white looks more white... I don't care if it's slightly less bright, it's too bright as it is right now anyway.
EDIT: Actually I just tried screen calibration under cyanogen rendering effects... using the N1 cool setting makes it a tad warmer, whites look white now, but it's SLIGHTLY less bright than before. Whatever, better colors, I like it for now until I exchange.

just for you info, the blue-ish white is the actuall true white . its the better screen than the purplish white. and once you comapre them both head to head, you are gona kiss your phone.
i am not aware of your other issues but if they are annoying you, then just exchange the phone.
god knows how many weeks i searched for cool blue-ish white for my galaxy S and then iphone 4. i hate the warm yellow /purple-ish color from my heart >_< " its a friggin defect "

This is how your NS should look in your screen while in the clock homescreen . If it looks any different, then its not right. Usually there's a purplish tint in the bottom tabbed icons on the lowest bright settings. You'll want to find one thats closest to this display

After doing the test mentioned above (Clock -> hit the brightness setting on the top right corner), I notice that the lower buttons are purple/pink tint.
Does that indicate a defective display? Also, after a few seconds, it dims even more, and the entire screen has a purple/pink tint.

Seems like some super poor quality control if there are huge variances in SAMOLED display tech coming out of Samsung... =[

purple = defective. bad screen
cool blue = good screen.
the end of the day = personal taste. but compare a purple screen to cool blue screen when you set the brightness to the highest on a white background. the difference is night and day

Gah, I knew there was something horribly wrong with the purple.
This is my 2nd unit and I'm not sure if I want to exchange it and take another risk of getting a faulty unit.
My first unit had a faulty back button and this one has a loose volume rocker (not too concerned about), and just found out that the screen is defective.
Now that I think of it however, I'm rarely on low brightness and high brightness.

good luck thinking about it before you go to sleep and you actually sleep.
and if you did, you will have nightmares about it

As I mentioned before, I'm not sure if this really considered a defect in the eyes of samsung because I've yet to see one displayed like the the 2 photos I've provided. I know this because of the inconsistencies I've personally seen with the N1 screens myself, and certain batches of N1 would have varying degrees of the purplish tint, some worse than others. It stills baffles me how they let this bleed over into their NS lines. My NS still has the issue but out of all the NS I've seen so far I've lucked up on the better out of the other evils.

As scary as it may seem, I did have nightmares about it!
I'm going to end up keeping this unit since I haven't ran into other large issues such as rebooting during phone calls, etc.

Yellow tint on S4 screen

I have this annoying yellow tint on my S4's screen, but disappears when the phone is tilted over 45 degrees. Is this faulty ? Shall I return it ? Or is there a way I can fix the gamma through an app without rooting the phone ?
Brightness set on full
Auto-tone, Auto-brightness disabled
Screen settings set as standard

I have this too, interested if this is a defect or just the colour tone of the amoled on the gs4

I have the S2 and it's blue compared to my display on computer, and I don't even notice it unless I put it against the computer display like you did.
Maybe try other display calibration, I hear you can change them.

Ok, been doing some google research on this -
There's always going to be a slight yellow tint to the particular amoled screen used in the GS4. However, to reduce the effect, set your screen mode to MOVIE.
Movie mode provides the best colour accuracy and also white point of the available choices. I can confirm this is the case having just spent a few minutes comparing colour charts to my girlfriend's very well-calibrated iphone 5.
So I would set it to MOVIE. The whites still won't be IPS display white, but then IPS can't touch the beautiful blacks on amoled. Horses for courses. Hope this helps.

@paddlyaz can you provide sources of where you got this info ? -- Edit : I just tried it, all that did was make the display washed off..Yellow tint still visible

It may LOOK washed out to you - but this is an AMOLED display, which is naturally very colour saturated.
If you compare the gs4 to an iphone 5 like I did just now, you'll see that even in Movie mode, the colours are a little MORE saturated than even the iphone 5 has to offer. The tint is a side-effect of this. IPS displays like the iphone may offer truer whites but amoled displays like the gs4 destroy them in terms of saturation and black levels.
It all depends on what you prefer on a phone.
In terms of the GS4, some people find the 'dynamic' and 'standard' modes vibrant and eye-pleasing - but they're not at all accurate and will exaggerated, innaccurate representations of your photos, videos etc. I have one photo of me in a yellow jumper (fashion mistake I know). When I have it on 'standard' it looks like I just came back from a two week holiday in Chernobyl. In movie mode, it looks exactly how it looks in real-life (i.e. still disgusting but accurate).
Here are a couple of links that describe it more:
http://www.gsmarena.com/displaymate_tests_galaxy_s4_screen_gives_it_the_thumbs_up-news-5928.php
http://gizmodo.com/5995376/galaxy-s-iv-display-shoot+out-how-does-it-compare

I wish I have another camera to show you the difference between my iPhone and S4 ... The iPhone's screen is bright white compared to the yellow tint on my S4. If this is a "feature" then it's not really efficient now is it =\
Maybe there is a way I can manually edit the gamma, this should fix the problem I guess. Or just exchange it for another one.

did you read ANY of my post?!
It's the trade off you pay for having perfect black levels and saturated colours.
The only way you're ever going to see perfect whites is if you get an iphone/htc one - e.g. an IPS display.
But then you're going to be stuck with 'blacks' that are actually grey. And that SUCKS.
People have differing opinions on which trade-off they'd rather have. Personally I'll take a slightly 'warmer' screen in return for having deep, inky blacks.

Hmm I see, so the display type is the reason why the yellow tint appears eh ? Interesting, thanks for the links too, going to check them out.

all screens will be slightly different from each other - but yes, amoled screens will almost always have either a slight YELLOW tint, or a slight BLUE tint - in other words, a slight exaggeration of one particular tone. If you have the time, do a google search and you'll see this was a common 'issue' flagged up on both the gs3 and gs2.
Your best bet is to do the following:
-set screen mode to MOVIE
-disable 'auto adjust screen tone'
-disable auto brightness.
You will never EVER see perfect whites on an amoled screen, and anyone who tells you they have them is lying out of their arse. Most reviews for the GS4 and also in the articles I linked you state that the GS4 is the most accurate amoled screen so far though.
If still disappointed, your best bet is the iphone5/htc one/nexus 4 etc

I think having an exaggerated blue tone is better than a yellow tone, in my own opinion.

Anyone else having this issue ?

I noticed this playing around with the S4 in the store. Still, much better than the S3 white point.

bad yellow tint
Hi everyone,
I received my s4 last week and found it yellowish as well. I have read everything regarding the screen yellow tint and the fact that it's because of the type of screen. I was going to give up but my girlfriend got one today as well and the comparison is very clear: her whites are so much better!
I have tried to take photos of them, and it looks greenish on the shots but you can see the difference. FYI the screen are both using the same settings: auto brightness off, brightness at the maximum, both screen mode in adapt display (I have tried the movie mode without noticing a change).
Mine is on the right if you couldn't see. You can clearly see the difference in the colour and the quality of the screen. I also noticed that the viewing angle are way worse on mine, the phone takes a greenish colour.
Finally I have very strong smearing/ghosting as soon as the screen background is black. For example when I am in the settings, if I scroll up and down, the thin lines separating the sections actually disappear whilst the menu scrolls. The thicker separator get a purple line until the scolling stops. Once again, the smearing on my girlfriend's phone is existant but much less strong. The thin separators are still visible even while the phone is scrolling.
I am definitely bringing it back to the store tomorrow. I am very disappointed with the screen even though the phone is great. I wouldn't change for a One, just for a good one.

I had the same yellow tint on screen and tried a few different firmwares thinking maybe its a software issue but nothing fixed it.
Picked up a new s4 last night and this one is perfect. The thing I noticed is the new one is assenbled in Vietnam and the old one
was assembled in China. Over all the build quality on the new one feels much better along with audio quality.
Maybe a quality control issues in some factories

You'll see it when you pull the battery, there should be a sticker there.
I am located in Toronto and we dont have any samsung stores here
so i actually bought another one from this dealer i found on kijiji.

I looked at mine and it says made in Vietnam... But I would agree to say that there is a problem with quality control overall. My guess is that they need to produce as much as possible to avoid any shortage. I had the same problem with my Note 1 and could be bothered to change it, this time I won't let it go.
I will keep you posted.

I had to go to another branch and thankfully they had a model with a white tone screen. I compared it there and they did indeed see the yellow-tone in my phone. I am getting a refund soon, it's not really worth all this trouble i'm fed up of the customer service experience with Samsung.

[Q] Note 3 Uneven Screen Color

I know there are a few different threads about various screen concerns, but this one is specific to color distribution. Sorry if this belongs elsewhere.
I attached a picture of the Note 3 screen without any screen protector while on the dark gray color from the LCD Pixel Testing app. Apologies that the uploaded picture isn't rotated properly. The bottom-right has a purplish/pink tint to it and the top-left has a greenish tint. It's not the camera angle/picture because I took another picture of it from the same angle, but upside down and the coloring moved accordingly.
I also took a picture of the Note 2 under the same conditions to make sure that this isn't normal for other screens, and the Note 2's screen was much more consistent. I've experienced uneven color distribution on the Samsung UN46B8000 TV, but not on a mobile device.
Does anyone else have this type of uneven screen color on the Note 3?
Thank you!

Im not sure why is this happening. Im now on my third replacement and every one has this hue or tint in different parts of the screen. Im not sure if its fixable but I gave up on samsung. I just hope it goes away after some time.

Thanks for the reply. I'm going to check out display models and see how the uniformity is. If they are worse than mine, I'll keep mine. Still, I think that Samsung should really work on this. I've compared it to the Note 2 and S3. All have better uniformity than the Note 3, which saddens me as I was really looking forward to this device.

I spoke to one of the tech guys at my work and he said it could be a power issue. The power source could be coming from the upper-left corner and it gets weaker as it goes across the screen, which could explain the gradient-like change in the display. If the pink is at the bottom-right for all our displays, it could be the explanation.
We looked online for a proper teardown, but we couldn't find one that showed where the screen power originates from. I don't know about this because I'm not sure if full/more power would result in a greenish-blue hue. The only evidence I can think of that supports this is that the Note 2 and S3 were overly greenish-blue in tint over the entire screen.
Does everyone affected have greenish-blue on the top-left that fades into pink on the bottom-right?

just tested mine with the app i got no tint or diffrent hue .. I've tested it on AUTO, Manual low, high brightness settings..

I have these problems since I own AMOLED devices, and that is now for quite some time (see sig.)! Me too had to exchange each device a few times until I got some with a almost perfect screen! On both N9005 I own so far the lower screen side is darker, although there are other significant differences between the two screens: the one of the second device is much more uniform! plus no1 has sharp pitch up in gamma on the leftmost 5mm over the whole side (maybe this screen has been cut out from the edge of the mother-substrate: the more from the center the better, due to principles of metal mask lithography)
I've done a few posts in regard to this in the past, if interested use the search function!

Another problem I have: When CUP is on medium to heavy load, screen brightness and contrast start to go up and down slightly each few seconds on all brightness levels, even on manual and lowest brightness! this happens on both devices, although here the first one is a little more stable! for me this happens always when in gallery for example, due to CPU load because of media scanning... Seems to be some load or thermal brightness throttling mechanism implemented (guess: in some part of the kernel)...

mine doesn't have a hue but on really dark colors (like the dark tapatalk theme) the screen color is uneven on the background.

I'm happy for you. For me, I gave up and bought LG g2 and I'm so glad I did. I just love this ips screen.

I'm wondering if it's there is edge LED lighting and the screen is just uneven.

My first one was like yours which seems very bad. Took it back got a new one, this one has the issue too, but its not that visible. I wanted to take it back again, but then i saw a guy who took 3 Note 3s back and the last one was the worst. So change it until you find one acceptable and next time wait a bit until Samsung gets better QC, or hope for another player on the phablet market.

It's probably not as bad as I make it sound. You can only see it if there isn't any light in the room basically. I took a screen shot of the battery status menu and cropped it to the all "black" part and put a black dot on it. In a totally dark room (doesn't mater what the screen brightness is) see if you can find the dot. It's pretty small you have to zoom in a lot. But using this image I can see the uneven lighting on the screen. If there us ant kind of color displayed though it's totally invisible.
I'm kind of worried about getting one that's worse too. that's what's got me not wanting to deal with it. A lot of them down here have been getting returned to best buy and Verizon because of a signal issue or battery drainage problems.

Nope. Obviously. ?

So I returned the first one and got another. This one is better but there's a big dark band that goes across the middle. It's not as pronounced as the last one though. -__-

Try this in a dark room. Using Display Tester app test card Grey #808080 and put the brightness in the screen tester to as low as possible as well as your phones brightness to low as feasibly possible. The check out the lower half near the home button. You will see it being slightly different and darker. Both mine and the wife's do it. Her's possibly a little bit more pronounced than mine. Normal, as I never notice it during day to day or night time viewing. Point being I have to go out of my way to find this so called issue.

i had same issue i replaced 3 note 3s then in white color there is no tint no screen issue..n checked 6 phones on shop..u r lucky if u get 1 phone with gud screen among ten phones..9 will be faulty and one will be gud....but my shop keeper is a nice guy..but really samsung should fix this issue.
..
people will complain about hardware issue after some time..when they will compare note 3 together..
coz i have too much experienced in note 3 replacement.
i had three note 3s n900 and n9005.And checked 6 note 3s...so trust me..some device perform gud some laggy..

can confirm this! and it was the same on note1, note2, ... on basically all amoled devices i owned from samsung so far!
the "problem" is the manufacturing process of the amoled screens:
they were cut out of a wafer. in the process of exposing the wafer with a light source through a FMM (fine metal mask) the exposure is not evenly distributed over the whole wafer. the more from the middle your screen has been cut out, the better it is! the gradients (down side darker, right side darker, ...) are due to the gradient light exposure of the wafer before cutting!
so it's all luck of the draw: atm i have one (!) decent screen out of 5 devices! the bad thing is: on this device the thermal throttling is comparable worse then on two of the other devices i have, but on these the display is very uneven!
so it seems to be a hard task to get a device where a) the screen is perfect and b) there are none of the other known problems (wobbly button, thermal throttling, noisy camera, ...) present!
thank you samsung!

Display Issues Thread

We can discuss display issues here. Here's my situation:
Let's be clear: MOST display have problems. My iMac I'm posting this from is tinted yellow on the left half and magenta toward the bottom right corner; my Nexus 7 2013 had edge light bleeding; 3 iPad minis retinas had edge yellowing; I returned and exchanged my way through 5 iPhones 5ses and 5 Nexus 5s before I found one without display problems; etc. But these faults are subtle enough that the general population isn't sensitive to them, or else they mostly don't care.
Sure enough, my Note 4 has display issues. I'm not sure if this is Mura Effect stuff or just bad quality control. Check it out below.

The picture above doesn't do it justice, it's a lot more apparent when you've been using the actual display in real life for awhile. Also disregard the scan lines. But notice about 1/3 of the way from the top, there's a subtle horizontal line where the display below it is more gray, and more yellow above it. And if you divide the display diagonally from the bottom left to the top right, then the left half is tinted yellow compared to the right half, especially toward the upper left corner of the display. And the entire right edge of the display is tinted magenta, which is more apparent toward the bottom right.
Above I used the Note 4's Screen Write ability to document the imperfections as I see them.
Don't get me wrong, the display is nice. But I will likely have to flip through several devices until I end up with a good display. Are you guys noticing some Mura Effect problems, or other problems? Talk about them here.
PROTIP: to see the Mura Effect imperfections on your Note 4 display, grab this image and view it in a pitch black room and manually dim the display to the lowest level.

All I see is someone who is a perfectionist

So far I haven't had a display Issue. I keep at full brightness at all times.
Anyway, I know people are having issues and I am sorry you are too.
I got lucky I guess
From the BadAss Note 4

I dont notice this at all on my white note 4. Even if it so faint then the difference is neglible. Its not really worth the trouble going through 10 different devices just to get rid of this effect. But i turned off all lights and its night here so no outside lights and i see nothing at all wrong with my display. i also dont see anything wrong in your images either.

OP def has issues.
I see grey lines on the image that I'm not even sure is an artifact of the display or what you purposely have showing on the screen n I do see the slight greying 1/3 the way down, but again, what do you have displaying on the phone to represent this and how do you know that image itself isn't creating the artifacts, not the display?
No way YOU get that many lemons... either you're too picky or your method of testing is flawed.

The gray lines are from the camera, I edited the OP to reflect that. The image is just a plain white image, the same one i used to demonstrate display problems with the nexus 5 earlier this year. It's not that i get unlucky, it's that displays usually have problems. The apple store manager let me replace my 5s to get a good one because he acknowledged the edge yellowing and that colors were inconsistent even across the 10 display models. He told me outright that displays are calibrated within certain limits, and every display will appear differently, but that edge yellowing is an actual problem and he could see it after I pointed it out. I can't be blamed that most people aren't bothered by these problems, or that they're too insensitive to notice them. And again, the pictures don't do it justice...we're talking about a display you hold in front of your face live and stare at for hours daily.
On my current Note 4 what i mainly notice is that the gradient, where the yellow tint of the upper left gradually blends into the magenta of the bottom right. For me that's noticeable constantly. I can't make myself not see it, it's pretty apparent despite the image in the OP not showing it off well. As for the horizontal separation between the milky upper 1/3 and the gray lower 2/3, I'm only actually aware of that whenever i scroll, because eyes are made to notice contrast so it becomes apparent whenever my eyes are tracking something as it passes that border.

Nope. Perfect display here.

my problem.... and a big one, i cant stop staring at it. lol

Starting to have buyers remorse, tempted to consider a 6+ if stores dont have stock to exchange this for soon. Its so gross, this is all i see whenever im using my $830 phone with the "best mobile display ever" according to display mate:
Also, not necessarily a problem just something i noticed, this display gets SUPER bright in direct sunlight (its max brightness is only allowed on auto brightness, you cant set it there manually). That makes all colors super washed out, its weird, but so far not a problem. What im writing about here though is something I've never noticed on an lcd displays: whenthe note 4 SAMOLED is at this max brightness because youre viewing it in direct sunlight, if you use your finger to cast a shadow on the display, it makes this really bizarre inverted shadow effect. Try it out, its kinda crazy!

Hey am having tmobile send me new device because of this issue,for me it was really noticeable in landscape mode browsing Web at night once eyes start to adjust to screen brightness, I can see on mine were one side is whiter and the other a greyish purple hue.

My note 3 did not have this issue.

It's highly unlikely that you're going to score a unit with absolutely consistent white balance across the display. I haven't had an AMOLED screen that doesn't have it to some degree, and i've had many. Even my Note 4 has it, but it's very difficult to see unless you're really looking for it.
When I first got the S4 a couple years ago I got a unit that was so bad that when looking at the keyboard in landscape it was clearly 2 totally different colors on each side, but I exchanged and got one that was much, much better, but still not completely 100% even. So you might try an exchange if you can, but don't expect absolute perfection. Most displays on most devices will have some degree of imperfection if you look for it, whether it's white balance issues, back-light bleed, uneven brightness etc etc. An AMOLED panel is still likely to give you a better overall experience than a comparable LCD.
As many others have said in this forum, just try not to look too hard at the finest details ("mura" effect for example)...it's still mass produced hardware. If your screen is that noticeable though, exchange it.

I had this problem with my black note 4, my wife has the white one so it was clearly there when put side by side, tmobile said it was ok so i had to take her phone the next time and then they said it was bad. Something interesting, the white ones seem to not have this problem.

Yea got shipping info for new device today,should be here Monday,which ever one has least defect I'm gonna keep.

my gf has a white note 4 from vzw .. i have a black note 4 tmo.. the only thing i notice between our devices is that hers has a slight yellow tint but her display is a little brighter.. i have seen this with my old iphone's if i ever had to get a warranty replacement form apple .. the replacements always had a yellow tint but were brighter ..
so far no issues with my note 4 .. i got lucky this time around :good:

Lol.... I think I beat all of you. This happened a few hours ago while I was using Yelp and Google Maps to find breakfast. Needless to say I'm pretty upset right now, but thankfully I have my Note 2 still, so at least I have something to use until T-Mobile helps me out. I'll be going there in a few hours to talk to a rep to request a new unit. Hopefully they don't try and **** me because I bought in via T-Mobile's website versus in store or because I don't have Jump anymore.

Dude is that the way it looks ALL THE time? Dude GO WITH THE WHITE ONE. I know I am I have the charcoal black and seems to be a bigger problem with the black ones than white I went in to the tmobile store and they had a white and black one. The black one was the same as mine (bluish white/warm color) compared to the WHITE note 4 the white looked great. Sure the black seemed brighter but I think that's what hurt the device in the first place. Sending mine in today or tomorrow already set.
Sent from another Galaxy! Note the difference!

Nick you should save yourself the hassle and just call tmobile customer care. The lady right away told me to send then my phone and as soon as they got the tracking number they will send me a new one. I'm going with the white if I can.
Sent from another Galaxy! Note the difference!

I exchanged mine 2 times because they had dust under the screen . Too bad I didn't check the screen uniform last time.
Anyway I'm on my 3rd Note 4. I don't have yellow/blue/purple tilted part but the white is not uniform as I can tell the top half of my screen is a little bit dimmer. It's something that an average user wouldn't notice but I do because I'm extremely picky. Anyway my dad's note 3's screen has uniform white so maybe you can score a perfect amoled screen but then maybe you'd end up with another problem like dust or dead pixel.
Sometimes I hate myself for having such good eyes lol

My black Note 4 also has some issues with the screen uniformity. My right side has a pink hue as described above. I don't have the yellow tint on the left. Also under direct sunlight the screen creates a strange effect, it looks like the colors are inverted. If you place your hand to create a shadow over the screen then the colors look correct without the inversion, it is a very strange phenomena. I am trying to decide whether to exchange it for a white one or get another black one.
Are the white version somehow better in quality control?

Mine was looked like this. And everyone in the BestBuy from where I got this said this is NORMAL. Fortunately I could able to get a replacement from the other BestBuy. The new one is still not perfect (it looks similar to yours), but I can live with it since I don't want to send it for Samsung's Warranty service.
(My local BestBuy said they can exchange the smartphone for only one time. If I have a problem with the replacement, I have to send it back to the manufacturer for repair. I couldn't find this from policy in BestBuy website, but that's what they said to me.)
