Some degree of blue bias is normal for any AMOLED display. Blue pixels burn out faster and are intentionally pushed higher to compensate for that. Most people given a choice perceive bluish white truer than yellowish white.

"Super AMOLED HD displays have a PenTile (RGBG, 2 green pixels for every blue pixel) sub-pixel arrangement, while Super AMOLED HD Plus has a RGB sub-pixel arrangement. The blue sub-pixels on the Super AMOLED screen degrade the fastest, so since the HD Plus has more blue sub-pixels, the display will not last as long as the former."

As soon as Android support ICC color profile. I have my colorimeter ready.
[Galaxy S III General] cba1986:
I never said that. Honestly i couldnt care less. I never noticed the blue tint of my SGS 1. Till i read it on XDA.
[Galaxy S III General] omersak:
Hopefully they'll calibrate it like they did the Note's display. It's absolute perfection, IMO - tack sharp with negligible tints and optimal brightness and superb color rendition, pleasant whites and no banding in the greys.

The Gnex display is great too save for the banding in grey areas. Plus it isn't as sharp as the note, still, a very pleasant overall experience.

The worst display i've ever, EVER seen was the GSII's, Horrible green tint with the slightest of shifts, on all three color settings. Went through 3 GSII's with the same result. colors and contrast were caliberated poorly too - webpages looked like absolute snot. especially the ones with light backgrounds.

Honestly, Pentile has become a non-issue at such high resolutions so i'm happy that the GSIII isn't using SAMOLED+
[Galaxy S III General] BladeZero:
Sorry for the noob like question, how would one test the display in shop?

type the following code in the dialer "*#0*#" and check the induvidual colors.
[Galaxy S III General] BladeZero:
Will that code work on all Samsung or just on the s3

[Galaxy S III General] vasp3690:
interesting thread. indeed the screen does look a bit pinkish from photos and videos and when compared to other phones. Question is how much is that a problem?

I mean, if the overall highest white is pink then yes,but if it only causes and issue when the brightness is reduced, maybe its not such a big problem
[Galaxy S III General] Zanr Zij:
My new S3 after warranty has less and smaller ink marks.

[Galaxy S III General] gaspernemec:
Got my s3 week ago and i am quite happy with screen however my whites are whites with pink taste only, nothing like i read here (large pink spots etc....), i have soma ink marks, one is little bigger and looks like o in upper middle of screen others are smaller and allmost unoticable, again nothing big, no lines etc....about black crush, havent noticed iz yet in youtube and video player, allthough i believe my phone suffers from it and i will notice it soon
[Galaxy S III General] bongobill:
pink pink pink

i tried to take a close up photo of my jeans in some dim light and ther was a large pinkish circle throughout the whole of the centre of the photo, i couldnt notice it on a distance shot, but deffinately there on a close up. any fixes? sorry if someone has already posted a fix, i am terrible at reading!
[Galaxy S III General] Kresstian:
That is something that comes and goes with many phones. It's the lens optics i think. It really depends on the motiv, and light that enters the optics.
[Galaxy S III General] abhifusion:
I got my phone two days before, and there is slight pink tint on the bottom 1/3 of the phone ... When I compared mine with another S3 which was without tint, I observed mine is more brighter than the one without tint also colors were looking more vibrant on my S3 :) ...
[Galaxy S III General] mits101:
Only had mine since yesterday so dont have much to say yet. I made sure too test the display though and i'm happy to say that similar to u, my screen is white with no tint, and i have 4 ink marks that are almost impossible to see (at first i literally thought there werent any until i squinred:D).

However i have tested for black crush and my unit suffers from this problem. i used filter your screen and that largely helps the issue but it warns that it can damage amoled screens so i only used it as a test and its not permanently on.

Would it be right to assume that black crush is mostly a software issue? Anybody try and install an AOSP rom and see if that altered the affect of black crush?

another small thing that i was a bit confused about is the blacks. i had read that amoled screens were able to turn off individual pixels and as a result produce very deep and true blacks, however the blacks on the S3 dont seem to be that deep? Anybody know why?

Thanks :)

[Galaxy S III General] gaspernemec:
I cant tell you about black crush on aosp. However about turning off of pixels, i have read somewhere that amoled screens can turn on and off individual pixels, but they dont, they always keep some voltage in every pixel, because turning on and off every pixel would take a large bite on battey-imagine, its like turning computer on and off or just putting it to idle (notice that on and off takes lots more of electric energy) my two cents here :-)
[Galaxy S III General] Condor Legend:
Hello, i have a uniformed yellowish tint on my s3, i'm fixing it with the app "filter your screen" with the blue value increased. But how about damage to screen? Can be this a reason to ask the new replace?

second question: i have the pink spot at center of photo on white backgrounds (like photo to a wall). Is this fixable with a new update? Or it is a hardware defect ?

I have the last 2 day of right of withdrawal (s3 vodafone)

(android 4.0.4 kernel 3.0.15-6718131)

Thanks
[Galaxy S III General] sav_uk:
Pink blotch is a hardware defect from what I've been told. A lot of S3 handsets have this defect but not all of them. I'd say it's grounds for return as I had four handsets with that pink blotch issue.
[Galaxy S III General] Condor Legend:
Thanks for your reply.

In another forum a user told me that the pink spot at center of photo is only the infrared used to set focus,and the pink spot can be saw only in a low light situations.

Is that true?
[Galaxy S III General] GiveMe2Beers:
Are out there GS3 without yellow tint?

Got yellow tint on mines (2 GS3) but when I tilt the screen 15-20 degrees it shows pure whites.

Annoying.
[Galaxy S III General] needhelp11:
I got a pink spot too on both cameras of my SGS3. It's only visible with low light like people said and on a white object. And my screen is yellowish too.
[Galaxy S III General] Condor Legend:
Try to use the app "Filter your screen" adding blue value
[Galaxy S III General] GiveMe2Beers:
Tried that and screen adjuster also, it help a little, but white are still not good enough.
[Galaxy S III General] Condor Legend:
I heard that the best solution is a custom rom with color temp settings
[Galaxy S III General] GiveMe2Beers:
Custom rom that allow to set color temperature? For Example?

Read a lot ang googled too, but couldn't find anything about that.
[Galaxy S III General] Wootever:
Abyss S3 Kernel has an option to change mdnie values.

You need to put that script into init.d folder and change the value 128 to something that fits your screen (from 0-255).

Hi guys... have any of you managed to RMA a S3 with ink marks? Haven't a clue how I'm going to show the store the problem... however my biggest worry is that I will get another phone with the same or worse problem.

At the moment, my ink stains are:

1cm by 0.5cm on the border by the power button.

Around 7/8 'spots' around the centre about 0.4cm high and 0.2cm wide.

[Galaxy S III General] amg009:
Guys is there any way to fix the pink blotch issue around the center of the camera while shooting white backgrounds....?
[Galaxy S III General] Condor Legend:
I heard that is the infrared used to set focus. So try to change the light-balance in camera options
[Galaxy S III General] clashie:
I seem to have one very subtle gradient band near the top quarter of the screen, it's literally invisible outside of the lowest possible brightness settings plus a dark room, but it still kind of annoys me that it's there. This is exactly what it looks like, except very, very subtle. Only one of them, it isn't striped all the way down. I've confirmed I'm not losing my mind and someone else can see it too.

That stripe picture in the first post is what it looks like, except there's only 1, and it's considerably more subtle.

Should I expect the entire screen to be absolutely without this? I get that the ink marks are an OLED problem, but I'm concerned about this band more than anything.
[Galaxy S III General] ZunRob:
Me and my girlfriend both bought a Pebble Blue S3 a few days ago. However, while on hers all the whites look properly white, on mine S3 white appears more yellow. This yellow tint is also visible on the grey and brown colors. At a closer look I observed that the front cover of the S3 of my girlfriend is lighter blue, mine is somewhat darker blue. Can this yellow tint be caused by a thicker coating on the front cover?
[Galaxy S III General] macdroid01:
I finally noticed I have a tint issue. I actually tried to see ink marks once at night, and didn't see any. LOL I'm not going to look any more. I have the Verizon S III. However, the bottom three quarters of my screen are tinted yellow, and it gets worst toward the bottom. I've verified it by using it with a white background in landscape and from multiple angles, and brightnesses, etc. Disappointing to say the least. But it could be worse. I compared it (with all the same settings e.g. "Tone Adjust" off and max. bright) to an AT&T S III in store. YIKES the one in the store was far more yellow on the whites. Looked horrid. Then I fired up a HTC One X. And was sad. Very sad. The display on it blows S III out of the WATER. It's just silly how dim the S III looks in comparison. I still might keep the S III. Everything else about it I love. I love TouchWiz. I loooove the handset. And I HATE the buttons on the HTC phones. There is no menu button. But there is a dumb "multitasking button". I know that can probably be fixed ROMing. I will probably root and ROM my S III with CM10 when it's final. For now I want to stay 100% stock. I'm loving my S III but this AMOLED crap has to go.

ink marks

i have ink marks on my SGS3 only on gray scale images. these ink marks seems like HDAMOLED and android logo.i have attached a few pictures with this awkward problem.
[Galaxy S III General] 10076757:
I returned 4 by using the front camera trick. If u take a picture of something white using the front camera, u will see a pink splodge guaranteed. Show them this and say my pictures come out pink. I did this 4 times. On the supposed 5th time I got my money back and went elsewhere and I managed to grab a blue one. And it doesn't have any ink marks whatsoever at all. Boom. Perfection at last
[Galaxy S III General] sav_uk:
Can I ask where you purchased your new handset from?
[Galaxy S III General] ruterjunior:
same problem here...

black spot's appear when backlight over image dark with maximum brightness

but only see in the dark room

this problem is very comun in AMOLED displays! my RAZR have too
[Galaxy S III General] treUse:
After having returned 3 S3s due to other problems, I can finally say that I'm satified: it doesn't even have ink spots :)
[Galaxy S III General] erto90:
is definitely the ( samsung screen protector LOGO ( the circle is very visible)) that seems dissolved in the screen
[Galaxy S III General] fasty:
It's difficult to see how the screen protector logo etc could conceivably imprint on to the screen "chemically" through the glass which should be completely impervious to chemicals.

I'm wondering if the device has perhaps been left exposed to bright light (especially sunlight), which has "bleached" or otherwise damaged some of the optically active pigments in the AMOLED by UV fatigueing...The variation seen after protector removal could be a "shadow" where it was less affected.

Just a thought!

white blotches on lock screen

I have not noticed the problems mentioned but, noticed something that have never been mentioned by others. I have noticed some white blotches on the lower right part of the locked screen when using a totally black wallpaper. This happens only on the lock screen since it disappears after you unlock it. I am using exactly the same black wallpaper as the lock screen so, I bet its not been caused by an imperfectly black wallpaper. It looks like a black cardboard that has been soaked by water droplets on one side and dried up later on making it look like the black had been washed out a bit.

Can you guys try to check if you have similar issues on your S3? This problem is so easy to reproduce. All you have to do is take a picture using your back camera while completely covering the camera. This will produce a fairly, if not totally black image. Use it as a wallpaper for the home and lock screens.

I believe this is not the amoled hardware issue but, a software issue on how the screen driver drives the pixels while on locked screen because it totally disappears when unlocked. Maybe the pixels and not turned completely off during lock screen mode in the effort to save power. In other words, the drive voltage were made to float (not zero or one in digital terms) so, was prone to inducted noise around that pcb area which is around the lower right of the screen. As you might have known, the mainboard is on the right side, exactly where the blotches are.
[Galaxy S III General] ste1164:
This is a shame I was going to get another S3 now am worried it will have loads of screen issues like the nexus. Can the S3 get banding on lower brightness like the nexus does? Mainly on grey/white screens.
[Galaxy S III General] buge boyo:
Thanks for educating me on oled screen I was going to ask for a replacement I am happy I read your post it really put my mind to rest,the ink blots don't affect picture quality really .
[Galaxy S III General] cba1986:
Look for black blotches near the power button. It looks like that a blotch grow there after a few weeks.
[Galaxy S III General] rookiegenius:
I bought my S3 at Costco and thanks to their easy exchange policy, Im gonna return my phone till I'm satisfied with the device. So far I returned 2... still waiting for the white one to come to my door.
[Galaxy S III General] hyandroid:
did you have your phone replaced? my original s3 has a big pink spot on the screen, I replaced it, but new one seems have the lower 1/3 slightly pink than upper screen. wondering if i should replace it again
[Galaxy S III General] Yusei:
My SIII got that too and i've change it.
[Galaxy S III General] jovu55:
Since actually getting my 32GB SGS3 10 days ago, I've done the test with a black background, resulting in four small blotches and a minute number of small mini blotches scattered. Only ever notice it in complete darkness and it very slightly bothers me (because I'm very fussy) but overall I can live with it.

As other people have eluded the SGS3 screen is still pretty awesome and produces great pictures, viewing media is amazing especially HD content. Just learnt about the Mura effect from a poster in this thread which makes me feel more at ease than I was originally. I can't really notice the Pentile matrix display at all tbh, seems better than SGS2 imo, reading webpages and text is great.

I am just really relieved because everything else is great as my other concerns were pink/yellow tints, screen burns etc.

Don't hesitate in getting this phone because it's a stunner, looks way better in hand - suit it up with a nice case and it feels and performs way better than any other premium phone.

Best phone purchase to date.

**Oh and again - thanks to this thread for educating me heaps about Samsung devices/technology...It's been a big help indeed**
[Galaxy S III General] GiveMe2Beers:
I'm on my third GS3 (Brand Vodafone this time).

This time I got a yellow shadow in the middle part of the screen (it gets whiter going to the top and the bottom of the screen).

Definitely a shame. :(
[Galaxy S III General] hyandroid:
Agree.

I am on my third too, still not perfect, but I can live with it.
[Galaxy S III General] GiveMe2Beers:
Hi man.

Can you explain what you got on your three gs3?

Cheers. :D
[Galaxy S III General] hyandroid:
First: pink spot on lower left

Second: light pink on lowee 1/4 screen

Third: almost good, but slightly pink on the left right edge of screen. maybe my eyes become picky after seeing the first two. :)
[Galaxy S III General] GiveMe2Beers:
Maybe Samsung can correct these issues via software update, like they did with the yellow spot on GS2? :rolleyes:
[Galaxy S III General] steveim:
i have black spots issue too. it looks like blob of ink. its very faint but noticeable when im on black screen with all surrounding lights off. its annoying the fact that something like that is there.
[Galaxy S III General] malyfsborin88:
I have black spots too and are visible on "black" screen. So when I take it to Samsung to replace my device, do they give you a brand new one or a refurbished?
[Galaxy S III General] jonstatt:
I have two S3s here. On one of them the screen uniformity is pretty much near perfect, and as you tilt the phone the whites go a bit bluish.

The second S3 is a bit more yellowy in the middle of the screen and gets more white towards the top and bottom. However when you tilt the phone, the whites go pinkish!! Also, the more the screen gets used the more uniform it is becoming (something that also happened with Samsung iPad 3 screens, glue?!). This one with pinkish tint shows more saturated colours/contrast at an angle than the bluish one.

So it seems Samsung have more than one filter type they put on the screen. One that makes whites go bluish at an angle, and the other where whites go pinkish!! The pinkish is much more noticeable. Head-on aside from the slight uniformity, the colour temperature of white is suprisingly similar between the two phones. Why would Samsung be messing around with different filters?

As an aside the bezel on the pinkish S3 is more bluish and had a newer software update on it to start with.

I have seen multiple HTC One Xs and while I agree there are aspects of the screen that are better, the variance between units is enormous. Although HTC use 2 screen vendors (Asus and Sharp), even multiple One Xs with the same screen type show SIGNIFICANT differences in colour temperature between units, particularly the Sharp ones. I saw ones that were pinkish and some that were very yellowish.

I don't know what it is these days, but nobody seems to be capable of producing consistent screens!

Neither of these two S3s suffer from bad (or any) mura although the one with the pinkish tint on angle, has slightly blacker blacks which makes it near impossible to see anyway.
[Galaxy S III General] Infinite Jest:
This will probably be the first and last time I buy an AMOLED screen until they improve the technology. I've given up at my 5th replacement and settled for a screen with two white tones (blueish white on the top half and more yellowish white on the bottom half). Either the quality control Samsung and its suppliers employs is complete crap or the technology just isn't up to snuff yet. It's a great phone, but I can't believe how incredibly inconsistent the units they pump out are and why they aren't screened for obvious problems before they leave the factory. I'm almost missing my iPhone (blasphemy, I know)...
[Galaxy S III General] hyandroid:
I agree with you. S3's screen is disappointing. But my Nexus S was good, I believe it's AMOLED too.
[Galaxy S III General] Ausboy 2011:
No problems with any amoled screen ever :D
[Galaxy S III General] hyandroid:
Once I got the first one defective, my eyes become picky. My nexus s was water damaged so I can not compare.
[Galaxy S III General] ABC_Universal:
I got 2 S3, one in June another one in July. Definitely no pink screen in both :)
[Galaxy S III General] specr1:
Hi,

I have the pink tint at the bottom of my SGS3. I don't have warranty. Does anyone know if Samsung will fix it if I pay them or knows of a website that will replace the screen?

Thanks
[Galaxy S III General] tian105:
so supercurio lied again. exact same as he did to the N7000 people.

promised to fix thing he cant, got people's hopes up and alot have donated to him.

So where is this display fix and voodoo audio? lol

not hating on him but one should do what he says.
[Galaxy S III General] sonic2911:
does the t-mobile s3 with new FW get any display problems???
[Galaxy S III General] tanjiajun_34:
He did delivered to Nexus S and Galaxy S users. Anyway voodoo sound I don't think he even promise for the Note. It does not use Wolfson sound chip anyway. Voodoo sound won't work. Anyway there is something like Voodoo Sound for I9300 already? In Siyah Kernel? Well its a port of the Nexus S and Galaxy S's version but it works as well.
[Galaxy S III General] specr1:
Does anyone know the cause of the pink tint problem? I want to get my phone fixed and I'm thinking of doing it myself.

Would I just need to buy a new screen?

Thanks
[Galaxy S III General] Cdjones187:
Screen = display, digitizer, and bezel. (digitizer is part of the bezel, which is glue to the display, and is likely the cause of inconsistent colors) Its all in one. There is a thread around here somewhere that a user posted a video on how to replace the screen step by step. Good luck searching though.. If I stumble on the post I'll update with a link.
[Galaxy S III General] Jose0726:
I just got my sg3 on sunday from t mobile & i was worried sick because last night whike browsing in dark room saw the blak ink marks on screen.. phone is on latest updates too :/ took it for a repkace thinking it was a bad screen but they couldnt see what i was talking about...
[Galaxy S III General] nudawa:
I don't think the back light of the two touch button is pink tinted too. This is photoshoped. Mine has no problem.
[Galaxy S III General] Infinite Jest:
This screen technology is complete crap. The first chance I get (when a new phone is released), I'm jumping ship for a LCD screen. 9 replacements and every single one had glaring screen flaws, among other non-display related issues. The one I currently have has visible adhesive under the glass, a blue tint on the bottom 1/4 of the screen, and "reverse burn-in" on the status bar already. I wish I had just kept my damned iPhone until the next flagship IPS android phone was released.
[Galaxy S III General] nikzDHD:
HTC One X+ :p

AMOLED is good but bit of a lottery to get a good screen. I love the deeper blacks in AMOLED. But honestly SCLD2 has to be screen of the year.

Let's see what these new 5" 1080p screens are going to be like.

I had 2 SGS3s in possession from Amazon and both were horrible with the tinting issues, my previous SGS2 was perfect but developed screen burn after 11 months, my SGS has screen burns.

My sisters AMOLED HTC One S is fairing well so far quite a nice and bright display.

It varies from device to device.
