The OLED screen on the GS3 is incredible because of it's intense contrast and instant refresh time, but there a many things wrong with it out of the box, and only because Samsung marketing is driving the settings for it....
The color gamut is too high. It looks good in the store but makes the colors look cartoony, and can decrease lifetime of the display. Is there something that can get it closer to the sRGB gamut used by Android? (90-110% of the gamut)
The autobrightness is very poor in this case, as it does not go low enough in the dark, and does not go high enough in the sun. Has anyone made a mod that has proper autobrightness values, with some middle values turned slightly lower for battery savings?
The white point is very very blue! This makes the display look more white, but this is actually very bad for the display. Since the reason why Samsung needed to have PenTile is because blue pixels die quickly, why is the white so blue? Is there some way to make it properly white (daylight, about 6500k?), in order for better color accuracy and to preserve display lifespan?
At some point, supercurio released a voodoo screen application, but since then I have not seen any sort of application that can properly calibrate the screen...
My cousin has one and it is not like that.. I would return it

Samsung anything with a screen is this way. Just go look at this TV, they are bluer than anybody else's. They look good in the bright showroom but in your actual house? Not so much unless you just love blue.
I am guessing a fix can happen in aosp/aokp where they have the screen calibration options.

As far as TV's go, those are way more easy to tweak display settings on than a phone display. I agree that a showroom Samsung is really really blue, but that is easily fixed in the color settings.

There is a forced level of blue in the service menu you cannot change without proper calibration equipment.
That is beside the point though. I know CM7 had a calibration setting. Does CM9/AOKP have this still? I haven't had a device that could run AOSP in a long time sadly.

I have a relatively new (1w) sgs3 and have notice that in the dark room when screen has a darkish grey too off-black background solid colour (even on the stock notification background) and with tge brightness on lowest setting,then there many blob marks in the screen.
I ran a pixel checker which is fine but this appears like a defect in the glass itself. I'm not using a screen protector yet.
Can anyone else notice these blobs, some of which are as big as 3-4mm diameters?

Haven't seen it on the SIII, but on the SII I have, this would happen with screen filter on lower brightness. I think that it has something to do with the level at which the pixels fire optimally. If they are under fed, essentially, the inherent flaws in the screen matrix (as in any manufactured item) become visible where they otherwise wouldn't.
I know this has been beaten to death, but it varies from phone to phone. My i9300 had a lot of blobs. My second one only really has one noticeable one. My i747 is almost perfect. It has little dots, but they are spread out and pretty much near the border of the screen. I wish it would have been the other way around...
please search before posting this topic has been discussed in great detail in another thread.
common on super amoled hd panels.
Same issue too. Checked with Samsung and they said it's common for the screen. Only occurs in black pictures low back light and dark room and it doesn't bother me

I got the AT&T SGS4 today and upon getting home I realized the lower left corner of my phone's screen has a slight pinkish hue to it. Is this common and I'm being overly anal and just need to deal with it or is this an actual defect with my phone? If this is something common are there any apps that can adjust screen settings to alleviate this? Is there a screen "break-in" time needed for colors to normalize on the SGS4?
It is a seriously small thing, but it just bothers me and will continue to do so for at least the first few weeks of ownership. Also I have spent 4 hours researching this, but all I can find on the internet are results for the SGS2 and SGS3 and Gnex screen issues, oh and a few threads on the Gnote...in other words the internet seems saturated with Galaxy making it hard to search.
Thanks for any answers.

I have the same problem the lower half of my screen towards the bottom has a slight pinkish purple tint to it that's only visible in Grey's and sometimes and other types of screens but it's definitely there. And no it is not normal just grab another s-4 and put it aside by side and you will see the difference. Go and exchange it if you can

I came to the S4 after two HTC Ones that both had build quality issues, I'm going to the give the phone a week to "settle" since I am tired of going to the AT&T store and maybe with enough screen on time it can balance out (I don't know, I'm just hopeful). In the mean time is there any app that can be used to adjust the contrast or gamma settings with or without root? I've been trying to find one so I can at least "hide" the screen difference, but so far the only thing similar I can find is "Color Temperature" settings that based upon the threads I've been through are only in Task650's AOKP.
I just checked mine on a white and grey screen and there is a very slight purple tint. I also now hate you for making me notice it because I never did before.
To be honest though it is barely visible and doesn't bother me. Reminds me of the screen lines on the gs2 that I eventually got used to and forgot were there.

Well i just noticed the dreaded screen smearing/purple haze on my new note 3 when i had the brightness turned all the way down, so i decided to check my new S5 and guess what its there too!
FU samsung how can they not pick up on this???
Yes there are fixes but it shouldn't be happening in the first place if you want to test yours out download the pic below, set brightness to 0 and zoom in on the pic and you will notice pink/purple smearing between the black and grey colours when moving the pic around.
Hmm wonder why they made all the menu bars green? now you know.
Don't see any problem in mine.

You need to have the screen brightness all the way down and make sure your looking real closely.
Out of the S4, note 3 and the s5 Samsung has seemed to make it the less noticeable on the S5.
What you could be seeing is the after image of the screen. You're seeing pink shade because of the way RGB is showing the color grey. You're seeing smearing because you could be moving the image around quite fast and the display is not fast enough to trail your fingers.
I followed your instructions and could see nothing that you are speaking of.
I have also previously owned a Note 3 and did not experience any "purple smearing" either.
In my opinion you are grossly overreacting.

I started the "infamous" thread over a year ago http://forum.xda-developers.com/showthread.php?t=2252445
Despite some thinking it was a software issue, it's simply a hardware issue with the panel.
The smearing occurs due to the native refresh times of the panel when going from completely off to dark shades, I.e black to greys etc.
The reason it wasn't an issue on older amoled screens was that the pixels were not completely off when displaying black, which is why in a dark room you could see a glow to blacks and also the "infamous streaks and blobs".
On the newer samsung amoled screens black is completely black, the pixels are not illuminated.
Samsung are just using cheap panels.
I spent a lot of money on an oled samsung tv there was the same issue. Putting a film on like sin city would highlight it. I returned the tv.
^S5 is the latest, so it's definitely new. So, was it really the panel?
What application requires one to view a dark grey image at 0 brightness zoomed in at 100%?
Come now, this thread is surely to attract the likes of trolls, or have I missed something?

Ok lets be realistic, the people saying their S5's are not doing it are ether one of 2 things,....
1. Plain stupid and don't know how to adjust their phones display to reproduce the smearing, example: "homer285 What application requires one to view a dark grey image at 0 brightness zoomed in at 100%?"
2. or in denial and don't want to believe their perfect s5's could have such a flaw.
Because all S5s and note 3s for that matter are all shipped with the same display hardware tech, and no you don't have some super special s5 that has different hardware from everyone else cause your awesome .
Now saying that there are fixes for the problem, one can use a screen colour adjuster to keep the "off black pixils" turned slightly on witch helps big time but kills ur battery dead.

Not black on whole screen, but you may see pure black parts when you watch videos that are not on HD scale. Also, around 95% of movies have at least one dark or low-light scene.

Most of us are neither of those two. Just because you experienced it, it doesn't mean that everyone has. Phones are not made in a single batch/production date. It's impossible to produce millions of S5 in a single day anyway. All products sold internationally have the so-called batch date/number to trace possible problems. My previous S3 have the black blotches when screen is dark and viewed under very low light, but my friend's has none. Now, my S5 doesn't have any screen problems.

Have fun with your "smearing" lol
I can confirm this too on my SM-G900F 16GB model... The Note 2 and S3 i owned didn't have this, but the S4 does and now the S5 also....
When having a black background (and lowered brightness) you'll notice it when swiping through the homescreen pages.
I don't know what causes this but i doubt it can't be fixed, yet Samsung continuous playing it their own way by ignoring the problem (the 'anti-smearing' update they once released was a joke)
This should only be a problem at night or in low light environments(typically when screen brightness is very low). I'm pretty sure it's a hardware limitation of Pentile AMOLED screens with the diamond sub pixel matrix, and thus affects all GS5's at low/very low brightness levels.
I've suggested this a couple of times on here, I'll say it again: 1.Change the screen mode to Cinema or Pro Photo.
2. (More importantly) Download Lux(free) and change the White Balance to Fluorescent. This slightly tints the blacks, and greatly reduces the smearing effect.

The S3 had a PenTile AMOLED screen and it wasn't affected by this. AFAIK it's due to the Diamond Pixel layout Samsung uses on the latter Galaxy series.

I too did notice a difference between KitKat and Lollipop. Throwing on Action Launcher 3 Plus and enabling wallpaper theme and using Tapet for daily wallpaper changes makes it sexier.
everything does look better and seems work way smoother than kitkat did for this phone
This sounds too good to be true, so the super amoled technology has finally been perfected through a software update? This is big.

So based on what you see on your note 4, do you think there is a chance that the lollipop update once available for my tab s 8.4 might completely fix those issues? It's the color uniformity that bothers me the most as the lower 1/3 part of the screen turns pinkish on white backgrounds and darker on grey or dark backgrounds, also viewing angle tints are very prominent even at slight angles. I have been under the impression that those are hardware issues related to limitations of amoled manufacturing or something, so to hear that it can be fixed/improved through firmware is good news I think.
They are hardware issues and LP will do nothing to improve them.
Sent from my SM-N910T using XDA Free mobile app
I don't know maybe it is placebo but when I got my phone I remember thinking that the color changes at even slight angles were very prominent. I even mentioned it to my wife that with the big screen at normal viewing distance was impossible to see the entire screen at a perfect straight on viewing angle and the outer edges of the screen were kinda off colored but if I looked at that part of the screen straight on it was beautiful I just figured that a big screen the edges were kinda off at angle so it was hardware limitations. But now whether I'm just getting used to it or its better because of lollipop update but it definetly is not as prominent to me. It is at least to me an interesting occurrence
The software update wouldn't completely resolve these issues due to the manufacturing limitations of AMOLED technology. However, the display uniformity is more acceptable now than it was in KitKat; the uniformity is more acceptable perhaps due to the material design implemented in Lollipop; also a few parameters may have been modified in the RGB values giving perception of a better display. I remember having a yellow tint on the Galaxy S2, and after flashing a newer firmware via ODIN, the yellow tint was gone. Definitely not a placebo. The conclusion: The AMOLED (hardware) uniformity issues are still present, but minimally, not as noticeable, and improved by software.

It will also depend on the degree of the uniformity issue on your display. Every AMOLED screen has a slight hint of uniformity issue (whether it is viewing angle tints or just the way the panel was aligned). Too much unevenness is indicative of a defective display, the tint shouldn't be that obvious and noticeable at appropriate brightness and display mode.

The screen on my Tab S 8.4 LTE has a yellow tint covering the top 2/3 of the screen then gradually fades into a pinkier/darker tone, it is not strikingly visible by any means, especially in higher brightness levels and on colorful backgrounds you cannot really notice it unless you know it is there and you look for it specifically, it's most noticable on solid white or grey, in games it appears as if the lower part of the screen is slightly darker than the top part, also AMOLED Cinema mode tends to mask it a little more than other modes in my perception, also tilting the device even slightly shows a blue/greenish tint. Are those the kind of issues that you had on your note 4? If so, how much did you find the Lollipop update improved them?

I noticed tint when tilting the display in KitKat. The degree of tint will very from device to device. Though Lollipop may have masked some of the tint when I tilt the device, the AMOLED anomaly will always be there, regardless of whether you have Tab S, Note 4, S6, etc. There is an improvement, still slightly visible, but nothing drastic; the update is not necessarily the cure.
Is it worth updating to lollipop?

It's fairly easy to prove if the update improves display uniformity. Download a free screen test app and set the screen to display a light gray scale image or whatever best shows the flaws. Take a screenshot under both KK and LP. Compare.
