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).

I agree with you
It's like my mom says not everything can be 100% perfect
Yeah I know what you're speaking of. I started a thread here about it: http://forum.xda-developers.com/showthread.php?t=877497
I went through this when I bought dual monitors for my computer. It is nearly impossible to find two monitors exactly the same. You will not know the difference unless you keep comparing it to others.

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.

Dumb question, but did you verify that the brightness levels in settings are set to the same values? Or at least compared the two phones when at the lowest and highest settings?

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.
Only be concerned if your screen looks like this
http://forum.xda-developers.com/showthread.php?t=882862
That would definatley warrant an exchange, because they are NOT supposed to look like that.
My Screen looks better than his I9000 though too, but that could be his camera too washing out the colors a bit

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.

bazinga.
hit under the belt.
Why not load up Google site in the browser to do your comparison? That way its identical.
lol
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.

In conjunction to the post, "blue tint problem," which isn't really a problem but anyway....
I thought it'd be interesting to create a poll to see where everyone's at with their Vibrants.
Please participate in the poll, it'll be very interesting to see...
So if you're on the blue side or yellow side, obviously submit yours accordingly, however, for neutral that's for those who have calibrated monitors that can get true comparisons to determine if it's neutral.
There's no need to lie here LOL..it's just for fun so the more accurate it is the better. Don't just click neutral if you don't really know for sure. Try comparing your phone first with other Vibrants to be sure.
Here we go!
It's slight blue, but related to viewing angle and screen brightness. Viewing straight on, it's pretty neutral.

I know what you mean. Could the SAMOLED screen perhaps slightly change in its color tone as it warms up?
When I fired up the two Vibrants I have that was turned on for the first time and compared it to my other two which has been in use, the two never been used phones screen looked identical in its tone/shade.
So perhaps over time it does change as it, "breaks in?"
Does anyone know if this blue tint will get better with time? Mine seems to be the same, wondering if I should exchange my phone.
Well, mine is more cyan, though I can understand people calling it blue and it's driving me crazy. Even with brightness all the way up, there is no real white. This issue will likely cause me to return my Vibrant - along with the cheap build quality - as my Nexus screen looks much better and neutral in comparison. Even my wife noticed it immediately though she also has a Nexus.
Neutral, I've compared with monitors and other Vibrants from my T-Mobile store.
The blue should fade over time..sometimes they put in a bit of extra blue to compensate the blue's lower life span..if you want to even it out use a blue background as your home screen for a while and it should even out >.>

Are you sure it will fade? Where did you get that info from, I know wikipedia talks about this and says the same thing, but wikipedia is not really that accurate. Where did you get your info?
I downladed an LCD test app from market, i'm running a constanst blue screen hoping it will help fade out the blue tint a bit. thanks

When compared to mine my wife's had a very strong blue tint to it. Since I ordered ours over the phone I called Tmobile. They overnighted me a replacement without any hassle, I'd give them a call and see what they will do for you.
posted this in the other "blue tint" thread too
"...since the OLED material used to produce blue light degrades significantly more rapidly than the materials that produce other colors, blue light output will decrease relative to the other colors of light...In order to delay the problem, manufacturers bias the colour balance towards blue so that the display initially has an artificially blue tint, leading to complaints of artificial-looking, over-saturated colors..."

I guess if your imagining a blue tint, or don't know how to change screen settings them maybe you need a less advanced device.

I guess if you did not receive a defective Vibrant with an extremely blue screen, even with brightness all the way up and power saving mode off, your not qualified to speak for those who did. Of course it would not make sense to you.
i dont know about you guys but every time Ive ever seen a white LED its always had a blueish tint (like automotive LED's) its really not that big of an issue
My display was noticeably blue the moment I turned it on... going to the T-Mobile store today to see if I can get a better unit with a more neutral color temperature.

It matters to some people more than others. If it doesn't bother you then great. It's not really fair to criticize people who are bothered by it--one should have a reasonable expectation for color accuracy of their display, especially for a device so touted as being a multimedia powerhouse.

I have that issue with the blue screen and for some reason I'm the only one who sees it, I work for T-Mobile and I was showing my co-workers that there is a blue tint to the screen and they didn't see it it until I compared it to another phone. I'm also a graphic artist and I guess we see colors that others don't notice cuss we have too that's what we do. I also had a issue with the screen, there was some pixelation on my screen so I exchanged it.

You know, some people here say every Super Amoled has a blue tint. I have to disagree. I've been comparing my vibrant side by side to other vibrants, and the screens vary from phone to phone. Samsung deffinately has some manufacturing inconsistences. Side by side to other Vibrants, my screen has a very visible dark grayish blue tint. Other vibrants have a slight blue/green tint. While other vibrants i've compared to have gorgeus warm whites. 1 vibrant had a very dingy yellow look to all the whites. So this is not in our imagination, the screens vary a lot on these phones.
My cousin just got the vibrant this morning, she had not seen mine. She saw mine this morning and says "why is your screen blue?" Put mine side by side next to hers, and hers has nice warm bright whites. All of our brightness settings were identical.
I'll be exchanging shortly when I have time.

So, does your replacement still show the blue screen tint?
I've got two incredibles side by side. Both are apparently listed as 'samsung_oled_display' with dmesg.
Right one has a purple tint that is more obvious on low brightness. But colors pop more, more contrast, saturation. On high brightness, whites and blacks look more right.
Left is slightly brighter on equal settings. Has a slight yellowy tint that's more noticeable on high brightness. But nowhere near as obvious as the purple tint.
Any thoughts? What looks more like the typical Incredible display people get?
it looks like maybe some of your LED backlights aren't as bright, or out completely. notice the shadow on the edges of the two sides? i don't notice a difference other than in one of the pictures, though. maybe do a better job taking pictures that aren't as shaky/blurry?
Best I could do, the incredible is my best camera and couldn't use it.
And which picture and which phone are you referring to?
I'm more just wondering why there's such a difference, and which one looks most accurate to what everyone else has?
3rd picture is the one i noticed it on. however, i wouldn't say....with the pictures i have in front of me....that either are too far off from what "everyone else has".
if you're that concerned about it, call VZW.
I had the same problem with a replacement, had to get a new refurb that didn't have a pink screen. Customer service is not aware of the issue, you might have to take it to a store and even the techs might not see it.
Sent from my ADR6300
I did, this is my replacement ha... I'm not going to ask for a third, I'm just deciding which one is more like the rest.
And you don't think either are too far from what others have? Between the two there's a decent variation, Samsung amoled manufacturing just vary that much?
Only the first picture can I see a noticeable difference
I'm aware of people reporting a pinkish tint, but I didn't think its the same, since this comes off as purple to me.
And yea the first picture is the most obvious, but if you just look at the color difference in white,gray,black for the other 3 pictures, you can tell they're different tones/shades.
Honestly the left one is 'warmer' in tone and the right one is 'cooler'. Though right has better contrast and is overly saturated.
I think I'll probably keep the left one even though the right one is hands down amazing looking in full brightness, but looks all purplish in low, which is basically the setting I'll be using the phone most in.
Amoleds don't have background leds, the pixels emt the light themselves, as fat as I know

OLED doesnt use backlighting
Just pick the one that is easiest on your eyes. Yes colours will vary differently by batch (not usually by this much but really I can't tell a lot by these pictures). Personally to me overall one doesn't appear as bright as the other, so if they are using the same profiles, I'd take the bright one (but that's just me).
I think you are making a mountain out of mole hill. They both look ok, yes different but acceptable. It's a phone, you are not going to be doing Photoshop or high end video processing. If it bugs you, by all means take it back and ask for an exchange.
Oh I did, that's why I have two
And no I'm not, I can easily ask for a third. But like I said I won't.
I just thought I can get some expert opinions from others, -and- start a discussion.
There was a thread regarding evo's @ i6.photobucket. com/albums/y204/blu3g/002and003.jpg
that got some discussion.

They get dimmer over time, so yes the brighter one if in newer condition.
I'd prefer S-LCD to AMOLED anyday just for the fact that I dont have to worry about the screen dimming over time or burning in.
My girlfriends is like that. We both got our phones at the same time last June, same screens. She lost hers, and while her new one is AMOLED it's pinkish. It's only REALLY noticeable when the screen dims.
.... Seriously? You're complaining about a tint... A TINT!!!! the phone still works the same right? my replacement has the purplish tint too but who cares nobodies going to look at and say oh man your phone has a purplish tint what a fag lol
He was just asking a question because like most people on this forum, we are intrigued by how tech works, and we like to ask why do gadgets so the things they do, he wasn't complaining. Everybody who is saying that he needs to stop complaining needs to calm down, this isn't 4 chan. If you don't know why the screens are different colors, then there's no point in you commenting on this thread, especially if its to talk down to somebody under false accusations like some of you are.

i jsut got a replacement in the mail a week ago and i saw the same differences between my old one and new one. And i've heard of this happening to other people. Here is a thread all about this. I havent taken the time to read it but im sure it has the answer http://forum.xda-developers.com/showthread.php?t=656128
P.S. Garrett, you sound like a real douche
I've seen similar in my phone. I had to turn it in for a replacement and the first thing I noticed when I booted the new phone up was "hey, that white looks more pink than the original phone." Just to make sure I wasn't insane, I showed my wife the new phone and she immediately pops out "hey, that looks pink."
It's not bad enough that it's really a problem, just a little different, and the difference only really pops out at low brightness. I'm not going to re-return over it. At least this one doesn't have the spazzed out and possessed optical joystick that my first Inc did.
Is it normal for the screen to be a bit yellow when the back-light is dim? While the back light is ~50% to 100% it's a nice clear white. When it's turned down though it has a yellow/green tint. I had an Epic before the fascinate, and it was always a clear white. Side-by-side the epic was also a bit brighter.
Picked up a Droid X yesterday, since it was the last day for the buy one get one free, and it's screen is even brighter than the fascinate. Which seems to contradict most of the reviews and comparisons I've read.
I'm wondering if this is normal, or if i should get it exchanged since it's only my 3rd day with the phone.
It's funny that you say something like that because I used to have the epic and the screen on my fascinate has colors off as well. whites look yellower and greys and blacks have a red hue so they look almost maroon. My brother's fascinate does not have these issues and looks exactly as my epic did.
edit: also, this is with any screen brightness not just minimum

Sounds like you need to exchange yours at least. I might take mine up to the store and compare them, just to be sure.
Does your screen turn a bit yellow when the backlight dims as well?

it is yellowish at 0%, yes, but darker greys are almost maroon as I said
it makes the lighter greys look green and the darker greys look maroon, so it's definitely something i'll be exchanging in the near future. I just need to have the time
My whites also have a yellow tint. Is this anything to worry about or will Voodoo ColorFix fix it?
I think my wife's phone has the same issue. After reading this thread I compared them and there is definitely a difference.
There doesn't seem to be a difference at the higher brightness settings though. (remove the space in the url to see my comparison)
This is at 0% brightness (my wife's is on the left)

I took mine up to the store today, and i'm going to exchange it for a new one tomarrow(store was closing). They said it was defective.

I would. The store should do an even exchange. After all, the screen is best part of the galaxy S phones.
My wife and I just got back from exchanging her phone, and out of two new phones they checked, they both had the same yellow hue... their display unit didn't, and neither did the associate's Fascinate who helped us. I wasn't going to make them open more phones up as this store has been really good to us.
The associate said he thinks that may just be the way they are manufacturing them. If that is the case, perhaps it is the software, and there is a setting buried somewhere that can be changed. I'm not sure, but I am curious to hear about everyones results on their exchanges.

Samsung did an awful job calibrating the display. Colors are extremely saturated(I'm a home theater buff and it looks like that awful dynamic/vivid setting.) I don't mind it though. I just wish this could display whites like my Droid. Maybe I should try returning it and see if I can get one with a working GPS and good screen?

I don't believe that it is just the way they are manufacturing them or else both mine, my epic's, and my brother's display would all be the same regarding colors. The colors should not be so significantly different between two units of the same model if they are manufacturing them properly. I will be returning mine and making sure they open them until the displays are properly colored... I am only returning one unit and I, like most consumers on xda, am not part of the majority they serve so I actually... well, notice the color difference.
Please don't put me in the "unwarranted exchange" club! My display really is off, and I haven't seen this in any of the other Galaxy S forums, just the Fascinate. I feel ripped off after having switched from Verizon to Sprint for the Epic, then being unsatisfied with my sprint bill/Epic switching back to Verizon and getting a junk display.

What's funny, and is actually kind of bugging me now is that my phone (without the yellowish tint) has noticeably dimmer capacitive buttons than my wifes new one. This might be due to it almost being a month old vs. one that is only a few hours. But if the LEDs are diminishing that quickly, what will they look like in another month, or even six months from now? I just don't think Samsung's quality control is what it should be.
As far as the screen, it isn't that big of a deal to me since the phone only has the yellow hue on the dimmest settings. If it were noticeable on brighter, or even mid settings then I'd be having a fit until we got one that looked good to us.
Your particular case sounds like it is way worse than what my wife and I have experienced. It sounds like a genuine defect, and you SHOULD get a replacement.
I just got back with my new one, no yellow tint at all.
The Vibrant has had similar issues with their displays. Ranges from a brown to a blue tint even. I've read a few about Epics having a yellow tint as well. So it's not unique to the fascinate.
I don't mind "vibrant" colors as long as the black is as black as possible. Even if it makes my ViewSonic look dull.
Now that I really look at it, whites are very blue tinted, while other colors are yellow tinted or over-saturated(which is on every one of these. The D1, D2, DX, and iPhone 4 are the only phones I've ever seen calibrated correctly out of the box.) Is this a defect? I am just happy these whites aren't like my friend Incredible's. His whites get black streaks down one line of pixels(it's hard to explain, but looks awful.) To return or not to return? If I return they better apply a new Invisible Shield for free.
Wow, you guys are really picky. I'm not about to say that my Fascinate's screen is perfect, but then again, no screen is. They ALL have flaws, one way or another. I for one have noticed that whites have a bluish tint, which strangely changes to a yellowish tint when I press on the screen. Does this make me want to complain and return the phone? Of course not. It really is not worth the hassle of going through that. Honestly though, I've never seen a screen that looks more awesome than this super AMOLED screen, despite the minor flaws. Guess there's just no pleasing some people. ;-)

The screen on my new one seems pretty perfect to me. No tints, and certainly doesn't change color when i touch it. Guess some people prefer to accept defects and substandard quality control.
Squeaky wheel gets the oil.
Went into the Verizon store today - the associate who I spoke with immediately recognized the problem, but I did pull out my brother's fascinate without color issues so we wouldn't have to go and check a floor model.
At first she said "Here, it's probably fixed" when she turned the backlight up, but when I showed her the difference between the two phones with the backlight dimmed to lowest. I mentioned the battery drain with it higher would not really be acceptable to me, she was more than glad to accept it as an exchange for a new Fascinate.
I also had my contract switched over to 1 year because I forgot to do that when I was in there and getting my old fascinate... sort of happens when you're sitting around for two hours. Picked up the extended battery too - not nearly as bad as people say unless you're shirt-pocketing it.
Took all of 45 minutes, I guess I was lucky - the longest part was the line.
Tints vary from handset to handset.
Hey just wanted to chime in.
I've compared Epic, Fascinate, Vibrant, and Captivate side by side. Here is what I found, almost no two screens have the same hue/tint/.
These are the following tints I've noticed.
Pink
Yellow (the best in my opinion)
Brown
blue/green
blue
blue/gray
When testing the phones, I set them side by side, and set the same brightness levels to test.
Why these tints vary so much, from individual to individual handset is a good question. I saw two Epic's in a sprint store side by side, one was blue tinted one was brown. Same exact settings. So strange.
Is anybody else noticing how dull the colours on the Milestone 2 is? ive looked around and havnt been able to find anybody else talking about it.
I took a few shots of it beside a ZTE Blade and a Zune HD (Zune on medium brightness, both phones on 30% brightness) and strangely enough the Blade's TFT screen looks identical to the Zunes OLED... and the Milestone looks awful!
im confused because the Blade cost 100 and the Milestone cost me 450!???
photos and a video here:
http://picasaweb.google.com/savagecabage/Milestone2TFTErrible#
is there some settings that im missing? im hoping there is. i feel like ive been screwed my motorola lol but i suppose its my own fault, i didnt really do that much research on the screen, i just presumed that a phone that cost 4 times as much as my last phone would have a decent screen
i got this info from pdadb.net, does this make sense to anybody?
ZTE Blade color transflective TFT , 262144 scales
Milestone 2 color transflective TFT , 16777216 scales
also there only seems to be about a 5-10 degree viewing angle on it, once the phone is tilted out side that the colour drops again, oh well
Do you have any screen protector or something on the MS? Are you sure screen brightnes is @30%? I have Droid2 Global and a Milestone (1) which both essentially have the same screen as on MS2 and it is not looking half that dull! True, colors aren't AMOLED like, but I would call it above average for TFT screen
Edit: just looked at the rest of the pics you provided and honestly the ZTE screen looks worse than the MS2 when it comes to color representation - everything feels redish/pinkinsh on it. The AMOLED is not comparable under this conditions. Take some photos at daylight to see "the other side of the coin"

no screen protector on and im using widgetsoid power widget and have both of them set to 30% using that. yea maybe its that the ZTE Blade colours are over saturated and im just used to look at them that way, but there is definitely some colours wrong and dull in places, like the red in the youtube icon is more of a washed out red than thier logo usually is
ah not to worry i suppose, i probably wont even notice it in a few weeks, ill be selling of the blade then so i wont have anything to compare it to anymore
awesome phone apart from that though
if i find some better examples ill post them,
thanks
I also noticed this the night I took my Milestone 2 home... I was a little concerned at first, but the soft colors eventually grew on me and I dont mind it so much now

Its not just me so! thats nice to know im not going mad. im sure ill get used to it soon as well, its not the biggest deal breaker anyway, im just into a bit of photography in my spare time so i like being able to look at photos on my phone in the correct colour
this guy says the screen is vibrant? i must go ask him how he gets it so vibrant, maybe theres a setting somewhere to turn the colour back on

"It is vibrant and displays colours well"
According to DisplayMate (which is an authority on displays) the Milestone Droid has the most accurate colors of ANY mobile screen. SAMOLED has awfully inaccrate and fake colors due to the poor pentile matrix arrangement. I dont know if the OLED screen on the Zune is full RGB or also pentile, but its colors are also "gaudy" and no realistic. Compared to my LG's IPS panel, the Milestone is pretty close. I suggest that your eyes are just accustomed to fake and bleeding colors, or your LCD might be a lemon.
The Milestone's display is IPS with full color gamut and true 24 bit color, not a cheap TN panel like almost every other phone. However, Android 2.1 and 2.2 have galleries that are only 16 bit, so pictures look compressed, not the screen's fault. Blame Google.

This picture indicates just how bad the ZTE screen is. That background on the right isn't even remotely close to being white like it is supposed to be.
It appears to me that your Droid brightness settings are too low (or is on auto dimming) because the Droid's screen should be much brighter--something like 550 nits for the Droid to 300-350 nits.
Also, your eyes are clearly accustomed to "gaudy" and inaccurate colors from OLED, whereas the Droid's display is very accurate.
Have a look at this DisplayMate article that breaks down why the Droid is accurate, Galaxy S' SAMOLED (similar to the Zune's OLED) inaccurate: http://lh3.ggpht.com/_BZtTwn-keT4/TSb4DpoadvI/AAAAAAAAAc0/0pqLgfd_Uik/s640/IMG_2833.JPG
I recommend manually setting the brightness on your Droid. Personally, I prefer the screen very bright. Let your eyes adjust to the Droid, and if you still want overly saturated/fake/inaccurate OLED colors, then please sell your Droid 2 to me
ive had my milestone 2 a month and when i look at it i still think how awesome the screen is, really sharp and clear, colours are vibrant, and ive had to turn the brightness down to almost the lowest it will go because its so bright! lol.
but as with most things peoples perception varies, what looks or sounds great to one person might look or sound horrible to another..

dont mind thoses pictures actually, using that camera wasnt the best idea, it white when looking at it, no red/pink in it
i think your talking about a different phone anyway, i had a quick look around display mate and couldnt find anything about the droid 2. they have stuff on the droid 1 but nothing on the droid 2. prolly a similar screen but might not be the same

yea at first i was thinking that my eyes were just accustomed to "gaudy" colours as you said but if thats true then it means that every screen ive looked at in the last few years has been incorrect.
i just put my xperia x1 and touch pro on ebay and realised that they look "normal", i put some photos on them to look at and both of those seem to be roughly the same as the zte blade, not as saturated as the ZTE blade colours ill give you that, but similar enough, and i have two monitors on my computer here and the photos have exactly the same "normal" colours, but then looking at the same photos on the Milestone 2 they look fairly washed out, even with the brightness at 100% there is a big difference.
i change the brightness settings all the time though but in the photo they were both at the same brightness so it shouldnt matter what % it was just to comapre them
anyway im definitely not imagining it, ive been doing photography and graphic design for a good few years now so my eyes are able to tell small differences between colour at this stage (i wouldnt be much of a photographer/designer if i couldnt) and its more than a small difference, enough that id bother posting a thread here to see if anybody else is noticing it!
well, ive come to the conclusion the screen on my milestone 2 it a lemon... or maybe motorola is the lemon. one of those two, or both lol
i wont be selling it anytime soon though unfortunately sorry im enjoying this phone way to much, the issue doesnt really bother me enough to do something crazy like that..
i just thought it was strange to see it on a 450 phone thats all
mine sometimes as problems, but not that bad :/
dude i really dont think your phone or the screen is the problem, i think its your eyes, just look at the picture of that Rovio screen! the left one is white, the right one is PINK! obviously the m2 has a much more accurate screen.

i totally agree about the sharpness and the clearness and the vibrantness of the screen, great detail in it. and i just realised all the colours are really vibrant apart from light blue and red, everthing else seem to be normal. the light blue looks the palest, and then the reds arent as bad but definitely still some difference compared to my computer monitors and other phone screens ive been comparing to.
ah not to worry anyway, i was just curious whether it was a problem everybody was having or if it was just my screen, i wont lose any sleep over it

yea i didnt really notice that when i was uploading the photo, i just explained that in a post a few seconds ago. it must be just the camera im using, both of them are the same whiteness when looking at them, i was just trying to show the difference in the red colour. the zte blade was at an angle too so i dont know where the pink came from, i just looked at angry birds again on that phone,and at an angle and its still white, stupid camera lol
Savage, I think you might have a bad screen. Can you compare it to another Global or exchange it? The Droid 1, 2, R2D2, and Global all have the same IPS panel as reviewed by DisplayMate, which thinks it is the most color accurate on phones. The Droid does use dynamic contrast, so its colors are sometimes deeper than at other times. I notice this especially when changing wallpaper. Some look absolutely stunning (almost as good as my IPS hdtv), but others are washed out. This is part of the dynamic contrast kicking in and Android's limited 16 bit gallery. I despise dynamic contrast and always turn in off on all my monitors. Unfortunately, I dont know how to disable it on the Droid

Yeah, I have the d2g, which I believe has the same screen as the m2, and I absolutely love the screen. The colors are very accurate and sharp, I used to have the captivate and I never liked how innacurate the colors were, whites never looked white, they looked grayish, and every other color had a bluish tint to them

Same here, my brightness is always almost all the way down except in sunlight where I turn on auto brightness.
Great Display.
I have a lot of phones with different displays including an Xperia with the Bravia engine which I returned for my MS2 and I would have to say that this is one of the nicest displays out there.
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.

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!

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.
