Is super amoled screen dying - Galaxy S I9000 General

SGS screen is awesome, even if colors are not really well calibrated...
Yesterday, I saw a recent Galaxy S and it was really brighter than mine (4 months year old)
I noticed a huge difference!
Did anyone of you got the same experience?

Insulting question perhaps, but did you check the brightness slider of both phones?

We just got 4 at work. The supplier told us they only had 1 left a few weeks ago and we had to wait until they got new stock so when they turned up we had one from an old batch and three newer ones. The one older one was very noticably darker then the 3 newer ones even with exactly the same screen settings. It also had a slight blue tint to it.

My brother and I both have I9000 Galaxy. The 1st phone (the older one) was very bright that it resulted in eye strain while using!
After about a month when I bought a new Galaxy S it was very dark compared to the older phone on same settings and same firmware.
So maybe its the issue with some phones or I am guessing that the older phone suffered from backlight bleeding! But now the screen broke and I bought a replacement screen from ebay.

Now THAT explains something. I have a pixel tester and when I set it to black, in a pitch black room I can still see the screen. Well now I know... You sure about that though? Even the Samsung Super AMOLED videos make a point of there being no backlight.

AMOLED does die over time, blue first. So as I understand it most of these AMOLED screens in phones have twice the blue pixels to make up for it over time. I would of suspected that the lifetime is a few years though, not months.

There is no backlight in S-AMOLED displays.

As you can see, there is no lamp, neither a white background needed for the light to reflect.

Thought so. So, can anyone explain to me why I can see my screen in the dark when the phone is showing only a black screen? Such as with the dead pixel checking app I used? Perhaps it does not correctly request true black but even noLED from these forums does it.

I would expect it's due to leakage current.
Each pixel on the screen is controlled by a transistor (actually probably more than one). Even when the transistor is turned off (and the pixel should be dark) there will still be a small amount of current leak through. I suspect that this is what causes the screen to glow slightly even when displaying black.
Of course when the entire screen is turned off, no power is going to the display, so even this small current stops and the screen is darker.

Maybe Samsung has switched to SLCD screens.
The rumour circulated few months ago that Samsung has stopped the production of the Wave and the Galaxy S smartphones because of the Super AMOLED shortage.
Maybe now they are shiping SGS with SLCD.
The SLCD screens are much brigther than SAMOLED.
Here is the comparison:

I highly doubt samsung would discontinue the SGS line for any reason. In fact, they just started to showcase the 7inch SAMOLED most likely for the next gen galaxy tab.
However, here's a comparison.

I'm sure it was an AMOLED Screen, easy to recognize...
I'll try to make some photos.

i got mine when it first came out and i have it on zero brightness setting and it is bright and clear (except in sunlight when it becomes as hard as any other phone to see)

ive tried about 15 of these phones and the screens on all of them were different when set to the highest brightness. The most common differences were darker and lighter shades of blue. a couple were more red than others and looked 'warmer'. The one im using right now is pretty neutral though not sure why that is but they all seem to be different.
(all 15 were running JH2 stock with no lagfixes on i9000m from bell)

Argh...
I have a dead green pixel towards the bottom of the phone... And now that i know its there.. I keep looking at it! Def wasnt dead when i got it
A good way to test the pixels is via the *#0*# menu... red, green and blue.

i always have brightness settings at the lowest and when i was using eclair rom everything was really dark. after flashing froyo rom i noticed straight away even at the lowest settings the phone is still pretty bright but green colour does not look good at all.

Do all the newer/newish Epics/Galaxies have yellow/yellowish displays?

I just got an Epic.
Reading several threads across the Galaxy line, there is apparently a variation in screen color temperatures. From my readings, I see a pattern where perhaps the newer/replacement units have yellower screens. At the same time, those newer units also get darker in auto brightness mode than the older units.
From my own observation, the color temp gets cooler as the brightness increases.
Is it possible that Samsung tweaked the auto brightness so that the phone now gets darker in order to save the battery? So perhaps the different color temp observed are a function of how bright the screen is?
I don't care for the yellowish screen on my new Epic. I like a cooler/colder screen. Comparing the Epic next to my LCD Evo and Touch Pro 2, it is outright yellow. Comparing the 3 phones next to my Nexus One, the N1's screen looks pink. (I can post some pics tomorrow).
Bottom line, I'm trying to decide if I should try to return/exchange the phone for another and hope for the best. I read that there are some potential software solutions out of XDA, but I prefer to have a phone that is natively "cold".
Any input would be great.
Thanks.
Mine's pretty yellow. :-( In brighter light, it is not a problem. Darker screen is the result of a software update. Got mine on launch day.

Thanks for the information. Before the software update, when the screen didn't get as dark, did it appear less yellow at the [pre-update] low brightness?
In other words, does the screen now look more yellow than ever since the update and darker screen?
Cheers.
I got my Epic on Oct 1st, and I haven't noticed this yellowish at all, but maybe I need to do a thorough side by side with an older model?
Did you get any pics to post up yet? I'm interested to see this
Edit: Sorry, just saw you said you can't post pics until tomorrow.

Just as yellow as always. Post-update, the screen dims more. At this point, it appears yellower. My Captivate also now dims more, post-update, and seems bluer at dimmest setting.

The only time I've had problems with my screen was when my phone had gotten damage from water. I'm on my 2nd epic and this one doesn't have any yellowish tints. Only about a week old now.
Sent from my SPH-D700 using XDA App
I picked up my Epic on 9/29 and don't see any yellow tint at all. I'm not an expert here but I think I would notice a tint like that. My blacks are very clear and dark also. I did notice that it seemed to run on auto brightness a little darker than it had...that was probably the D-118 update after I had it for only a few days.
I will follow this thread and see where it goes.
I don't think the screen color variation is based on release date. I have two of them since 8/30. One of them has a yellowish tint compared to the other. They both have the same DI18 update.
It seems like a coin-toss what screen color comes. I wish we have a tool that would allow easy color temperature adjustment.
I read a thread about a way using a modified kernel, but it would be nice to have an .apk that works (even if it requires root).
I got one on launch day that had more of a blue tint to it. I got another one last week that was a refurb, and it definitely is more yellow.
Weird. I just got mine today and it's very cool (read: blue) compared to my Evo... being a photo guy, this drives me nuts. I prefer warmer diplays.
Sent from my SPH-D700 using XDA App
I have one of the cooler screens, and I kinda like it.
My thoughts:
1) Samsung is trying to extend the life of the blue oLEDs by altering the color temperature of screens. Since this seems to be happening independently of ROM version, it's probably something they're doing with firmware.
2) (IMO More Likely) The screens on different phones came from different assembly lines or different production runs, and have a slight variance in color production. The production date of the phone wouldn't necessarily matter in this case.
The only project I know that deals with the color temperature of the screen is voodoo:
http://project-voodoo.org/color
I currently have it running on my ROM. It adds a new "very low" brightness setting a the bottom that's much dimmer than even the lowest one available in DI18. (Note: it doesn't interpolate levels between them, either. Meaning there is a big jump in brightness from the voodoo lowest level to the DI18 lowest level, which is the next "notch" up on the slider.) It also adds a brightness level at the very highest brightness, which noticeably makes the display warmer. (The highest and next-to-highest brightness notches are the same brightness, the difference being the highest one is warmer.) At this point of its development, it's really of no use if you want to make your screen warmer at all brightness levels.
At any rate, the project leads me to believe that, with further development, we could have an app that allows us to freely change all the color settings for the display for all brightness levels, save them to profiles, etc.
The idea of the screen getting warmer as you decrease its brightness might be a natural phenomena, or just perceptual. In my experience, colors usually seem warmer as you decrease the intensity of the light. This is even true of light on a physical object.
My screen looks awesome. No yellowing or anything. I wonder if there is a difference based on who made the screen for that particular Galaxy S phone? I remember reading an article when all the Galaxy S phones started rolling out saying that Samsung was having trouble with the manufacturing of the AMOLED screens. Perhaps they started cutting corners.
However, there also seems to be issues with auto-brightness, etc...I have that disabled on my phone and the brightness set on its lowest setting (which is plenty bright for me and all my viewing needs) which may be the difference? But, I have cranked it up from time to time just to show others and I still don't notice any yellowing.
Is there a specific test image or something where one could view that would show/exaggerate the effect people are talking about? I would be curious to see...
Thanks for the great input and information.

Here is a quick picture taken by a Touch Pro 1. Sorry about the quality. I can try to take better ones if there is interest.
From left to right - Evo, Epic, Nexus 1, Touch Pro 2. All with auto-brightness on.
In real life:
The Evo looks whiter (cooler)
The Epic looks much yellower (warmer, almost greenish)
The N1 doesn't look as pink as it appears, but looks the darkest
The Touch Pro 2 looks the whitest (coolest)
To my eyes, the Evo/Touch Pro 2 looks good. Although the picture shows the Epic looking pleasant and only slightly warmer, the white elements (clouds in wallpaper, browser backgrounds etc.) look yellow/green.
Edit: Notice the Menu, Home, Back, Search menu LEDs look whiter than the screen. See the contrast between the two makes the screen look yellower.
I've owned 3 Epics since launch day. First one had a good screen, 2nd one had a yellow tint, 3rd was perfect.
The build dates of the first 2 were 10.08 and my current one is 10.09.

By perfect, do you mean that it is not yellowish? It's interesting that the first two phones with the same build date has two different color screens...
The Epic I have has a 10.10 build date. It's yellow at dimmed levels and color temp gets cooler as it brightens up.

Not all Nexus S SAMOLED Displays are the same

Hi everyone,
I'm starting this thread to show you guys that not all Nexus S AMOLEDS are the same. I purchased a Nexus S on launch day from one store, and my brother bought a nexus S from another best buy store. We were comparing each others phones, and mine turned out to be darker than his, specifically the whites. We compared our screens at full brightness, and we set the same backgrounds, and his was noticeably better looking. So I went and exchanged mine, the new one I got still suffered from having darker whites, but it was not as bad as the first one, so when we compared them again, his was still better. I took a few pictures of the new one i got compared with his (on right). It may not look like much, but if you look at it in person, it's very noticeable when they are next to each other. I think you guys should compare your nexus s with a display model at a store, or with someone else to see what I'm talking about. I think it's easiest to see what i'm talking about if you look at the search widget. Like I said the first one I had was worse, but I'm comparing the newly exchanged one (left) with my brothers (right).

lol thats true. it made me laugh lol
download a solid white wallpaper. set the brightness to the highest. if one of them is cool blue white then this is good screen. if its warm yellowish white, then its a bad screen.
also there is the issue with pinkish disaplay. download a solid gray wallpaper. set the brightness to the lowest, if the gray turns to pink a little. you have a defective screen no matter what others tell you. if it stays gray " like my old Samsung Galaxy S " then you have a perfect screen.
AND there is also the grid pattern matrix you can see on the lowest brightness on the same gray wallpaper. ALL of them are more visible on the Super Amoled screens, just try to get one that is not very noticable.
if you got all those 3 perfectly " with no dead pixels or stuck pixels. then your phone worth alot.
i sold my galaxy S USED more than i bought it NEW because of these effects when i mentioned them to the buyer and he saw with his own eyes the difference. plus it didnt have single scratch on the whole phone so it was like a brand new.

No one's nitpicking. It's a matter of what you're willing to settle for. I paid my 580.00 for a phone to display the colors correctly. I didn't pay that much for the display to change colors just because I lower the brightness.

ya, after i took pics, i realized they were not on the same page on the home screen.
This is a very common issue on the Galaxy S phones too. Different suppliers are used in the manufacturing process resulting in some screens with warmer color temps, and others with cooler ones. The Engadget review of the Nexus S specifically called out a warmer temp by the way.

ya, i actually made sure they were both brightest, and when they are both on the lowest, you can tell one of them displays brighter whites. But the first one I had was worse than the one I have in the pictures on the left, it's hard to notice that you have a screen that does not produce nice whites, unless you see another nexus s that does a better job.
I actually like the ones on the left, the ones on the right crush the blacks, resulting in basically everything washed out, even if it "looks" better to you, it isn't from a calibrator prospective.
The Evo 4G had the same thing going on with its display. HTC used 2 different Manufacturers for the screen, One Novatec, One Was Epson. I believe the Novatec panel had darker colors (warmer?) resulting in more of a purplish color on blacks (what ll_l_x_l_ll calls pink for whatever reason) While the epson didnt have any purplish tone, but most say had a washed out look.
I would say though that on the nexus S, probably 99% of them are going to have a little purplish effect on the lowest brightness setting. If the OPs brothers phone has no purplish color, that would be the first i have seen. Ive seen many many demo units, several video reviews, and even the 2.3 rom ported to other galaxy S phones, and they all have the "purplish" display.
All my whites on my phone are really white, and blacks are really black.

Yeah my camera isn't great, it was poor light but it was enough to show the difference.
My i9000 screen is pretty incredible, I'd be impressed if I saw one better.
Oddly though, you say that if it turns blue when the brightness is turned right up, it's a good screen - my Nexus S does that. But it's yellow when the brightness is low.
Personally I think I'm going to take your advice in another thread. I'm going to return this phone for a refund, enjoy using my i9000 for a while as it's now apparent that the screen is excellent (I never really had GPS issues either, so I'm pretty lucky), and go around stores when they have stock to find a screen that compares favourably against my i9000. I'm in a nice position that I can do a side-by-side comparison each time.

So, I guess not many of you have ever messed around with the LCD monitor in front of you (if you have one).
Mine I can set to be a cool white or a warm white.
Here is the real problem... Your brother is smarter than you. You see, there is a difference maybe in the screens. But instead of him *****ing about it, he likely just said his was better. Thus leaving you with the **** screen.
The tables could have been turned if you would have said "HAHA your screen is broken, and mine is better" the second you found the screens were different. Then it would be him here all upset about the screen.
The things people ***** about on this form are just crazy. And no, I don't care about how much you spent on your phone. When you buy any product you should only have a expectation that it is usable, not perfect. And thats mostly because perfect is mostly opinion when it comes to things like this.
Also, this is a phone, not a pro display marked for having the most accurate color production.
What kills me most is the people who take phones back over and over for problems that only exist in their heads. All you are doing is raising the cost of phones and keeping them high for everybody else.

Galaxy S2 screen quality

I've just got a new S2. I thought my Desire was good but this is fantastic.
However an iPhone-owning friend took a look and said "the screen's not very white is it?" I compared it to his and he was right - very grey. But the brightness was set to auto, so I turned it up and it was a lot whiter. But then he said "it's very green". And there is a greenish tint.
So I compared it two two other (about 3 months old) S2s that people have at work (using the *#0*# tests).
And my screen is definitely inferior: less white and more off-colour. Yes I did check that the screen modes were the same (eg standard/dynamic/movie) and that the brightnesses were the same. None of the phones had screen protectors on.
I know sometimes there are differences in screens, often because they're sourced from more than one manufacturer. But I thought Samsung made these screens?
So in essence, the screen on my phone seems to be worse than others, and markedly less good than my pal's iphone - for which I will get no end of ribbing!
Is this a common trait? Am I seeing things? Should I return it?
Love the phone otherwise. FYI it's brand new on Virgin Mobile in the UK and is running 2.3.4.

Try updating to one of the 2.3.5 based roms and I would definitely recommend trying out supercurio's "Voodoo Screen" app from the market(combine this with the movie preset found in settings->display->screen mode) as well. Just compared my SGS2 to an iPhone 4S and I'm really glad I didn't make the switch, as while the latter does have an edge when it comes to screen resolution, the former more than makes up for it with its 4.3 inch super amoled plus display. The iPhone's browser was a little bit faster, and the camera better, but I still I preferred the SGS2. Once it gets ICS it'll be absolutely amazing.
No don't set the screen to the movie preset AND use Supercurio's app at the same time !
But You'r right set it to the movie preset the screen will be more color-respective
Supercurio's app is great although still in progress. I'm also used Screen Adjuster to compensate for the greenish hue (red is set to +2 and blue to +5.
I ran into another application yesterday here on xda that let's you adjust sharpness and hue... let me see if I can find it again.

Why not? Looks a lot better than it does on standard.
You have to understand that the screen technologies used in each phone is different.
The iPhone uses an IPS screen.
The Galaxy S II uses a Super AMOLED Plus screen. It's not very good at handling whites, but it has the advantage that it doesnt need any power to show black pixels (unlike the iPhone), so its more black and more efficient at showing blacks.
Great replies, thanks all.
Since posting stijnr, I've got Screen Adjuster on, and interestingly my settings aren't a million miles from yours, red +4, blue +6. One thing I do miss from the Desire is the optical track button - I'm finding adjusting things that need a little bit of input to be quite tricky on the touchscreen.
Toss3 you made me laugh, not intentionally I'm sure! I will flash a new rom at some point - god knows how many I got through on the Desire - but I will spend a few weeks appreciating this stock ROM! Best thing about Virgin Mobile is it's non-branded and as Samsung shipped it. Not even any logos on the case.
Good point kwazi on the different screen technologies. But that doesn't explain different S2s having different display characteristics. Anyway I'd rather have this larger screen - the iphone screen may be beautiful but it looks very... small these days for what is a premium handset.
I'll check out some other S2s in stores in the next couple of days. If this is what they're shipping I'll live with it. If it's a 50/50 chance of the other screen I might try my luck.
Most of the viewing on our smartphones involves looking at whites, webpages for example, NOT blacks. And the Iphone 4 displays superior whites than the Galaxy s II.
I've gotten to the point where I think I would be happier with an regular lcd screen.
While the tech is nice in Super Amoled Plus, the quality and consistency of the display that's being manufactured is all over the place.

I've just got a new S2. I thought my Desire was good but this is fantastic.
However an iPhone-owning friend took a look and said "the screen's not very white is it?" I compared it to his and he was right - very grey. But the brightness was set to auto, so I turned it up and it was a lot whiter. But then he said "it's very green". And there is a greenish tint.
So I compared it two two other (about 3 months old) S2s that people have at work (using the *#0*# tests).
And my screen is definitely inferior: less white and more off-colour. Yes I did check that the screen modes were the same (eg standard/dynamic/movie) and that the brightnesses were the same. None of the phones had screen protectors on.
I know sometimes there are differences in screens, often because they're sourced from more than one manufacturer. But I thought Samsung made these screens?
So in essence, the screen on my phone seems to be worse than others, and markedly less good than my pal's iphone - for which I will get no end of ribbing!
Is this a common trait? Am I seeing things? Should I return it?
Love the phone otherwise. FYI it's brand new on Virgin Mobile in the UK and is running 2.3.4.

You're comparing apples to oranges here. iPhone uses IPS technology, while Galaxy S 2 uses SAMOLED +. You're going to see differrnces between them. Personally, I wouldn't worry about the differences, or even see them as drawbacks; as each display has it's strengths and weaknesses. Industry standard resolution for most smartphones is 800x480, which is quite good on a screen size of 4" or larger.
Next time your friend pokes you about your display, remind him that his iPhone is still 3g device.

no, he's comparing apples and desserts, not oranges!
I compared SGS and SGSII with auto brightness and manual lowest setting.
SGS brightness with auto or lowest setting is at cca 50% brightness level on SGSII, I think Samsung sets brightness range quite down for saving battery life and users dont have to use Screen Filter app in the night
But imho auto brightness is low for me - at the edge of usability.
I remember when I first got this phone about 10 months ago, the greenish/blueish tint was so very much visible on the screen. Even when the screen is off, I can see a shade of blue on the reflection of the screen. But then it gradually "wear off" until the green tint disappear completely after about a week later. I don't know if it really disappear or just me being used to it. Or maybe after I update it to 2.3.4, 2.3.5, 2.3.6, I just can't tell. But I certainly feel it's not there anymore.

Screen disappointment?? Anyone else?

Hi guys!
First off I wanna say I love my Note!! I have the Korea version as well.
Anyway, I still have my Galaxy S I which I ended the contract to get a Note.
I have to say as far as the "blacks" are concerned, the Galaxy S I wins hands down and also the text/color is sharper and even brighter than the Note.
I tried to take side by side photos but this was the best I could do to show the difference. Both phones are at max. brightness

The pics do not do justice. In person there is a real difference. Even the capacitive lights on the bottom are brighter and whiter.
Not a big deal though when my Gaalaxy S isnt being compared to the Note. Just bothers me a bit personally
Thanks!!
Its becoz of the resolution . Galaxy Has 480 x 800 and in Note 1280 x 800, their is a lot of difference in these too models. anyway Supercurio is working on color issues on Note. lets Hope for better result.

After installing Screen Adjuster free from the market ..I just upped the red a fraction [+3] to get rid of the slightest green tinge to my screen.
Then installed Voodoo Screen from the Market and set it to Native Mode... this has fixed 90% of the banding issue on my Note.
Now the screen is beautiful and can hardly fault it.

Coming from a galaxy s with a perfect screen i have to agree that the black levels on the note is not as good and yes picture quality on the first generation screen is better even if its just plain pentile and non hd resolution.
People who started with the galaxy note are easily blown away but those who started with the first gen need more to be pleased. I also started a thread about this before and got the same results on the black levels.. im hoping that hd samoled plus can redeem the samoled family.
I think it is an amazing screen!!! I love it, about it being less bright, god I think the note is too bright. I never have it on full brightness unless its really bright sunshine, and in the dark I wish it would go darker, but it won't.
And the black levels!!!(I'm sick of hearing about this in the this forum) some people are so anal about this, I mean I can only just about tell that the screen is on, on a full black screen when I'm in a pitch black room, which I did to test the blacks. So 99% of the time you can't tell, and even in a pitch black room as soon as theres a pixel of light on the screen your eyes adjust and the blacks look black again. Secondly how many of you that are bothered about this, actually sit in the cinema or watch tv or when on the computer, say oh my good the blacks aren't quiet black. I can pretty much guarantee that all the screens in your life aren't LED so why bother so much about it on your phone?
I also love the screen. No disappointment at all!
Would you rather have 480x800!?
This is brand new technology! It pushes the limits of what can be done at consumer price.
And people are complaining!? WTF!
edit: I owned a SGS1, but I like the Note's screen way more. Much sharper.
Although I must say I'm not experiencing the issues I read about on the forum.

Are you joking???
I worked a few years in an industrial R&D department and designed new products, but we NEVER would have dared to release a product with such massive quality fluctuations (problems) onto a mass market! Especially when the screen is THE major unique selling argument!
Fine that YOUR screen is fine for YOU, but sorry, your arguments are pure ignorance! You do NOT have this issues, fine, then why judge about their seriousness??

Jeez, dont buy a samsung nexus then because that thing is a mess. Signal fluctuates so badly that its kinda funny. Fake screen size (the android buttons are actually on the bottom of the screen, reducing the screen size to the razr. The sound is a joke, the battery useless. Match that with no sd card slot no hdmi and the headphone jack at the bottom of the phone and youve got a 600$ flop.
I bought it for my 12 year old and even he doesnt want it. He wants me to bring it back and get a razr....
BTW, i have a bad s pen and the trademark samsung pink hue in the middle of my camera but asude from that, i love my note. When i saw it in youtube early 2011 i knew it would become my daily phone web surfer.
I wish for the same phone with S amoled PLUS, volume and sleep buttons not across from each ither, no pink in camera, mute button (like iphone) and the sane type of notification light as on the samsung nexus, micro hdmi out and quad core
try the free wallpaper called "no wallpaper" by simplicity apps. The blacks that you see with that wallpaper are amazing and it is free. i often use my phone at night when my child is sleeping, so lights are off and dark and see pitch black screen.
have 2 htc desires at home with amoled screens and the note screen is way better than that. have seen SGS and SGS2 screens and the note is definetely much better than that.
also try the wallpaper (free and paid versions) of KF Flames or KF Flames Donation by kittehface software. the blacks on that are also awesome with equally awesome flame effects. prefer the stock setting than variations possible with paid version but bought paid version just to support developer as liked free version.
the screen on even the sgs2 is no comparison to the one on the note. is your phone stock version or is having different roms affecting the display?
ICS should sort out most issues as its 32bit colour .... (or it could be 24 bit not 100 percent) ,,,
no wallpaper works a treat ... also lowering red to 3
still some apps which are lower density look like they have lines on .. but if you take screen shot they are still there when looking on pc so its the app not the phone
this phone rocks ... never ever going back to the half eaten apple ....

Where in my post am I "judging" about "their" seriousness?
If you find the screen their "major unique selling argument", why did you buy it before doing research on the screen?
If you are so worked up about the screen, why don't you get a replacement or trade it for a different phone?
Why do you point your frustration at someone who bought a phone he likes?
Because you bought a phone that you do not like?
Really, if you are so pissed off that you have to enter a forum discussion this angry. You should return the phone.
If you worked in a research and design department you must be a smart guy. You know getting angry won't get us anywhere.

The blacks on my old S2 is way deeper than the one in the Note.
Disappointing for sure.
But i'll take sharper screen over deeper blacks any day.
Well I was the proud owner of two notes this week, first one had a screen which used to tint between pink and green, so I got Amazon to send a replacement, which came today.
Alas this one isn't rendering the blacks properly and makes Black & White photos and videos look awful, pity as I'm a photographer and wanted to show client photos on the note (First note rendered Blacks great, just the white balance kept going off every odd second or so).
So two notes being returned, not taking the risk again.

I'm not sure how the black levels are perceivably different from one OLED screen to another, whether it's AMOLED, SAMOLED, SAMOLED Plus, or HD SAMOLED.
I mean, think about it...
All OLED displays are actively lit, which means that each pixel is its own source of light as opposed to being, essentially, active colour filters for a backlight, like on an LCD.
Let's go ahead an use 24-bit colour for the following example:
Basically, each pixel is able to register 256 levels of intensity per colour, which is represented by 8 bits per colour. And since you have three colours (Red, Green, and Blue), that's 8 bits times 3, hence 24-bit.
In the case of an LCD, where each pixel is essentially a filter, blocking or allowing backlight through, a bit value of 0 for any particular colour would mean fully blocking light, and a bit value of 255 would mean fully allowing as much light through as possible.
However, since the backlight in an LCD is always on, regardless of the image, the front panel isn't always able to completely block all the light, even on a completely black image. That's why you're still able to see a little bit of bleed-through, even on the best LCD's.
With any kind of OLED display technology, this is not the case however. On an OLED display, each pixel is essentially a microscopic cluster of light emitting diodes, and since each pixel produces its own light, there is no backlight whatsoever. Thus, on an OLED display, a 255 bit value for a given colour means full intensity, and a bit value of 0 simply means "off."
Q.E.D. on any kind of OLED display, true black is truly black in the same sense that when a light bulb is turned off, it's completely off.
So, if you're perceiving a difference in the black levels between respective OLED devices, it could be simply that you're not viewing a truly black image. The image might contain pixel bit values close to 0, but not actually 0.

proving Oled (amoled brand name) superior unlike what your told by mainstream media!

Your told, lcd is brighter in sunlight which is the main reason your tokd Lcd is superior or at least thay say amoled is inferior. Wrong,its because if default settings by the makers. Once rooted with proper kernel(almost every device has em) you can do with amoled what you cant do with lcd. Double the color multipliers from android default of 200 to 400. I use in order of RGB, 320/320/400 to achieve perfect white and black. Also the battery myth,lcd drains less. Thats bullcrap. Amiled black pixel achives pure black because its actually OFF. that is main reason it uses less power than lcd. Instead if going on and on I will just show u proof. I will show you picture of my LGOG(sprint optimus g) and my even aging gnex side by side in sunlight with my shadow on half the screens to show its actual sunny lol. A pic says a lot more than my Bloveating. Im using my sgs4 to post this and used its awesome camera tontake the pic if pic does not show in op I will post in first post. Have a great day peeps.

Pics wouldn't attach.must be because of using phone
Pic
2 different pic styles,img and jpeg clearly shows that even with a shattered and pentile matrix amoled screen its brighter in the sunlight. Even did my shadow in it so no one would say....sun wasnt out lmao. Sorry naysayers proof is in the pudding and the gooey pudding is right in front of your face. Proper kernel with amoled is brighter and better battery saver than lcd. Lcd is backlit anyway and most high end phones will use it in the future because it can be bended and manipulated and LCD can't because it is backlit. Only low end phones will be lcd in the future.
I agree with what you've said (I use Samsung phones primarily), but it is true that when displaying white, it uses 3x as much power as an LCD. On mostly black, you're correct; very little power draw.
Tell me about AMOLED burn-in. Since you are increasing the luminosity, I would suspect that burn-in would be faster?
Keeping my eye out for this one...very interesting.
Do you guys mind if I ask what this "burn-in" is and how to fo about it?
Very interesting indeed.

Similar to plasma screen televisions, if you leave an image on the screen for a long time (much more than average), you'll see remnants of it permanently. However, if it's anything like televisions, you can fix it by displaying a white image on the screen (entirely white) for a few hours. I've never had this happen to me and ive owned almost all major Samsung phones. Nexus S, Galaxy Nexus, Galaxy S II, Galaxy S III, Note 2, and now S4.

Yes burn in can occur on older like the gnex. Newer amoled is less likely but always set time out of 2 min when color multipliers are set to max. Best settings,for pure white is ,320,320,400 rgb color multipliers. Sorry should have talked about burn in,my apologies .
of course

Just remember in all aspects except maybe battery power AMOLED is superior if your rooted and have a proper kernel (there there look for em) amoled is superior and infinitely more controable then LCD, period. Sorry naysayers look at proof in sunlight
