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

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.

Why not load up Google site in the browser to do your comparison? That way its identical.

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.
Today I showed the screen of my galaxy s II to my iphone4 owning friend. We both loaded up bbc home page, and the white background on his phone looked much better than on my phone.
On my phone the white background looked cream in colour, where as his displayed as pure white.
Will this be able to be fixed with vodoo colour?
It can be helped with Voodoo color, but it can never look like an LCD based display since SAMOLED screens don't have the LED backlight in the back. And also, an iPhone 4's display has already been proven to be a bit blue tinted which makes whites look brighter when they're actually a slight shade of blue. I've spent a lot of time calibrating my Nexus S screen with Voodoo color and I can safely say the result is a more pleasant shade of white than my friend's iPhone 4. Also with Voodoo color I can boost the brightness higher than what the stock specifications permit so it's even a brighter white than the iPhone 4's if I want it to be, but it consumes a LOT of power.

the nature of LCD and OLED makes the colors differ here in America. It also makes the colours differ in England and most of its former colonies.
You can try setting the separate brightness setting in the browser settings to 100% (it is separate from general brightness setting in the phone settings).
I bet it would still have a different hue if you look at them side by side.
You can also try taking a friend with an iP4 that is a year old to a store that sells iP4 now, and compare how they look - you will probably see some difference there too, side by side.
He was saying to me, "oh your screen tech hasn't evolved yet, you cant display proper white", haha, "my text is so much sharper than yours".
It was true about the text, my heart sank when I compared BBC homepage in portrait mode. His text looked MUCH sharper than mines. But then he has got a much higher resolution.
I really did feel humiliated, I just want nice pure white like the iphone4 has. I know I don't have a backlight.

If you want to humiliate him, ask him to show you a black image. Then laugh at how much light leakage he has. Then play a high quality youtube clip like a movie trailer with some action scenes, then laugh at how slow his pixel response is (ghosting). Also while you're trying to play a high quality youtube clip... remind him that he needs to be on wifi in order to do it because he only gets low quality over 3G =)
Trust me I'd take the SAMOLED over an LCD display any day. Same reason I have a plasma TV and not an LCD/LED one.

They are phasing out plasmas because they are more expensive, eat more power , are harder to make, and can't compete with LCDs in price.
Real video buffs still prefer Plasma for its true blacks and great refresh rates.
I'm not gonna let this get into a TV debate but it's well known videophiles and avid cinema/sports watchers will always choose a plasma TV over an LCD because of the purer blacks and insanely faster pixel response (no ghosting like an LCD/LED). The mere fact that LCD/LED TVs even have to QUOTE a pixel response time indicates an inferiority.
And this also carries through to phones. If you don't believe me, try it. Pick up any HTC phone and compare it to any Galaxy phone. Go to a black menu with white text... perhaps the settings menu and scroll up and down. You'll notice MASSIVE text ghosting on the HTC LCD screens but none on the SAMOLED screen. Please, don't come back claiming things you haven't tested yourself with no facts to back it up.

Real buffs prefer high quality LED panels, plasma simply can't compete with the definition even if fast moving imagery is sometimes better. And I know this as someone who has owned high quality sets of every type.
Plasma's days were numbered as soon as it's monopoly on extra large panels ceased to exist thanks to LCD and then LED technology allowing 42" and above panels to be financially and technically viable with no loss of quality.
Still, we can agree to differ on all that if you wish.

I fail to see where the comparison between SAMOLED and LCD is relevant to a comparison between LCD/LED and plasma.
Oh, and I have tested myself.
What do you mean with "pure white"? To me it sounds like iphone has colder color temperature, that is not better, just different. In fact that would give less natural colors.
Try to change color temperature on your pc monitor to understand what I mean, a warm temperature of 6500K is more creamish than a cold temperature of let's say 9000K.

Obviously, I'm well aware of the technicalities of all current TV technology or I wouldn't be entering a debate about it.
Anyway, agree to differ and move on, as said derailing this thread is pointless.
Ask him to play a flash video from the browser And it is true the iphone's display is fairly impressive but I prefer the bright colors, larger size, and better power consumption of the SAMOLED+
Are you aware that the GS2 screen has 2 different brightness settings? It has the normal brightness, but lower down the menu it has a setting 'Auto adjust screen power' This actually dulls whites when there is a lot of white on the screen to reduce power use. If you untick it the screen is a lot more pure white.
Oh and on the subject of TV screens plasmas are getting a boost from 3D. 3D plasmas are much better than LED/LCD because of their reaction times. Much much less ghosting and as a result deeper 3D effect. A full HD plasma is still the best screen there is right now. Much less harsh than an LCD, better blacks, more realistic colours and less intense whites.

Who cares about which screen displaying bbc has better white. This baby has everything, 1080p, bluetooth 3.0, wireless n, hspa+, dual core, android (!), better battery and I think the samoled+ can display colours much better. Also no gay itunes and you do not need to jailbreak your iPhone (which makes the iPhone instable and ****) to just get freedom
Edit: forget about these things
4.3" screen, 9mm thick, 116g, micro sd slot and more.. seriously that phone rapes the iPhone

funny that you fall for that
put his iphone in the sun and say "whats white good for if you can't see anything?"
they're different techs. besides, true white is subjective. then theres like 150 other reasons why the SGS2 is technically better, and why the iphone5 will actually be very similar to the SGS2.
I can confirm this "cream" or, as I would put it, "yellow" tint to the screen and whites in particular. It's not right - I consider it a fault. My old (now current) SGS has the most perfect, even whites I've ever seen on a phone - even beating thr iPhone 4 in my opinion.
The SGSII is horribly bad quality as far as I'm concerned. I see nothing in SAMOLED+ that improved over SAMOLED. It's actually more grainy, too saturated, viewing angles - bizarrely are off, and blurs slightly when scrolling. What the hell is up with Samsung?
i am wondering what Samsung was thinking
when made of this.
Natural mode has washed out colors and normal mode
has over saturated colors .
We need something between.Is that so difficult?
ur thead is a joke
There are no oversaturated colors
All AMOLEDs are like this and I think display is very good.
Natural mode is pretty much perfect imo.

Coming from an WVGA TFT LCD on the HD2, the Natural Mode on the SGS3 seems to highlight the best of both worlds.

Standard mode is over saturated especially in games
and when browsing.
An extra mode between standard and natural would be
ideal for 99% of people.
They should just release all phones with a screen calibration mode after the first boot up.
People fail to realize that humans only see about 10 million colours so that the 16 million available, regardless of screen technology, is all there natural or not. There could be a variety of factors that contribute to AMOLED looking less natural but if I were to hazard a guess.
- people are used to seeing LCD looking colours.
- the LEDS are closer to the screen on AMOLED.
- Complete blacks trick our eyes into seeing colours around the black abyss as being brighter than they really are.
And of course the obvious such as a coloured organic Light source vs a white light source plus colour filter. And also the backlight needed on LCDs.
I think consumers just have to be desensitized to AMOLED displays and it will start to look natural. Or Samsung should do a better job with the natural mode and mimic LCD better. Or they should just give free reign of colour calibration like they do on HDTVs and add a back light. So if you like AMOLED, turn off the backlight. If you don't, leave it on. Barring the texture of the LCD colour filter, an AMOLED display with a backlight would look just like an IPS LCD display.

You know what is a joke? All the US versions don't even have a screen mode option. Oversaturation is nothing new for AMOLEDs but it can be remedied and has been remedied before, simply by providing an option. A lot of people like the contrast and viewing angles of AMOLEDs but don't like the excessive colors. I guess Samsung thinks Americans are all colorblind and took the extra effort to REMOVE the option altogether when they tried so hard to make everything else the same. The international S2 had color adjustments too, but not my T-mobile one. Then there's the terrible audio capture. Always taking two steps forward, one step back.
I quite like having an option to change my screen settings rather than not having an option. Thank you Samsung.

Due to the chipsets. Samsung used the television engine. The screen modes on my international SGS3 is the same ones as on my TV, producing nearly same effects (TV=LCD, SGS3=AMOLED). Sony uses their Bravia engine in their phones.
Hey guys, you do realise people are entitled to an opinion, right? Stop dismissing the OP blindly.
I happen to agree that the default profiles are not as good as they could be. Simply accepting that AMOLED is oversaturated by nature doesn't mean something can't be done about it in software. So before jumping down someone's throat, perhaps consider that they may have a legitimate concern.
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.

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?
I have no smearing, probably its all in your shorts lol.

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.

Your right. I had that in mind, but was confusing Pentile and the Diamond pixel layout as one and the same. My mistake.

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.

wow, pathetic. I hate all the BS threads about how samsung screwed us on the screen. Basically, by saying to turn down the screen all the way down and looking closely, in a dark room, you are asking somebody to look for a problem that never happens in a real world scenario anyways? WTF is up with all the people looking for problems in technology? Honestly, why in tha hell do people always try to find the tiniest this and the smallest that in every piece of tech they own and then bash the constructor for it, things that in the first place only appear in VERY SPECIFIC SCENARIOS THAT YOU NEVER ENCOUNTER IN REAL LIFE?

hello, 2 days ago i bought a refurbished gs5, right out of the box i felt like there's something wrong with it..
when im looking at the screen (especially on a white background) i can see its yellow-greenish. when i tilt the phone forward and backwards (taking the bottom part of the phone closer to me/further away from me)
the colors are perfect, like my brother's lg g3. what is the deal? is the screen defective? is it normal for this type of screen? the s5's screen is brighter than the lg g3, just for the record.
when i watch youtube videos, everything is greenish, when i tilt it a little bit, it looks almost as good as my dell ultrasharp monitor.
thanks in advance..
No, it is not normal. I might as well return it and get another one. I bought a SH unit and it came with minor burn-in, but that's not as bad as the yellow-greenish tint you're mentioning. Does it happen in download mode too? Or in recovery, if it's rooted with custom recovery. If yes, time to swap it for another refurbished. If not, we'll see.

thank you for your reply!
the rom is stock. after using the phone a bit, i feel this tint is just normal. its not VERY yellow, but when im watching vids faces look a bit greenish. its not critical, but not very accurate. still, when the screen is dimmed, it has a lot more contrast and looks much better than the washed out lg g3's screen (when its dimmed).
look, it might be just the way the screen looks. compared to the lg g3, is has a lot more contrast, but when im looking at images, the lg looks identical to my dell monitor (im a photographer so its very important to me), are you sure the galaxy is supposed to be accurate? are the white supposed to look as the lg? on the g3 the whites are a bit red, on the galaxy they're a bit yellow-greenish, but when i look at photos i took, the galaxy looks too warm. when i tilt it a bit, the whites turn a bit blueish, but its still better and more accurate than the yellow it normally is. are you completely sure it isnt the general look of this particular screen?
just for the record, its still yellowish in download mode
sorry for the long comment, im just trying to figure out what to do.,
AMOLED is over-saturated because Samsung is Samsung. Check a custom kernel which will be able to let you tweak the colours. I recommend Boeffla Kernel, because it lets you modify: R G B value, saturation, Hue, Display value and Contrast. Play around with all of those settings if you want to fix it using software.

thank you my friend. just for clarification, when you view a white background at "cinema" mode (which is the most color accurate) are the whites yellowish? when viewing in "Standard" mode, the whites are pretty good, but colors are SO SATURATED. and again, thank you my friend!
To my eye, the colours look washed-out, but that is because I am used to the oversaturation of the AMOLED. And yes, the white is yellow-ish.

How can I put it, uh, the S5 seems to be fine. The G3 is more vibrant, to be honest, but there is nothing wrong with the S5 in my opinion. Again, this is through my eyes, which are very different (and slanted), because 1/2 Jap, the colours on the AMOLED are better than on the LCD. Do you have both phones at the same brightness, and the colours are set nearly the same? Because that can sometimes make the difference. Send me that image, i'll load it on my Galaxy S5 and take a picture to show you how my screen fares.

the gs5 colors arent better, they're too warm :\.. in the photo the colors arent accurate, because the screens are too bright, but the lg g3 is identical to my dell monitor, the galaxy s5 is very warm and causes images to look almost orange. i shot the image of the gs5 and the lg g3 with my dslr, so it will look different than if you shot your gs5 with a phone camera. anyway, look at the image, tell me what you see at "standard" mode, tell me if the colors of the image look warm, and if looking at a bit of an angle changes the warmth of the colors to be colder (and much more accurate). thank you mate for the help.
for the record, the lg g3 look less greenish in real life, and the gs5 looks a tiny bit less warm. the photo (of the 2 phones) isnt accurate, but its close.

I see what you did there. I loaded the image on my S5 and, to sum it up, at least on my phone, with my eyes, comparing it with my 17" Samsung Syncmaster monitor, the colours on my screen look the same as in the G3 in your picture. I have my screen on Adapt Display. And in cinema mode, the colours are ~1:1 when putting my S5 next to your G3 in the picture, so yeah, your S5's screen is miscalibrated i suppose.

If the replacement also has these problems, just quote me back. Or just quote me back and keep me updated. When I will go to one of friends' place, where they have really professional monitors, i might as well compare the colours.

Now with an actual example, i can confirm to you that on the white google background the screen gets colder when you tilt it like in the video. And it also has some green tinting on the bottom. Again, our eyes are different, and this is my retina, my phone and my brain.

true.. one last thing, i have stock 6.0.1, when i change the display mode to "cinema" from "standard", the colors are accurate, but the whites are yellowish, when i change it to "standard", the whites are white, but the colors are over saturated and unrealistic. do you experience the same thing?
when i change to "dynamic", colors and whites on the internet, photos, video and such, look amazing and almost identical to my dell, but in games it looks just like standard mode, over saturated and too bright. im frustrated!

In dynamic, it changes according to what android thinks its on screen, or rather said, what colour profiles Samsung defined for games, internet, pictures, movies and so on. Unfortunately, with the properties of OLED, cinema mode tends to have rubbish whites. That's because the panel is OLED and your DELL is LCD, no matter if its TN, VA or IPS. The difference in technology is the base of your "issue". I keep my S5 on Adapt Display and forget about colour accuracy because AMOLEDs are natively over-saturated.

yeah then i think my gs5 is perfectly "normal" lol. ill just keep it at adaptive, its the most accurate for photos. by the way, my friend's gs6 looks a lot better. in cinema mode the whites are actually white, and the colors are better than the s5. i guess samsung improved it over the s5. i only paid 220$ for the phone (its considered cheap in my country, prices are horrible here) and i have a one year warranty. ill just keep it, its better than the lg g3 in sunlight, and when i dim the galaxy to 40%, its brighter and nicer to look at than the lg g3 at 60%. weird. well, thank you for the help, i guess im done here haha
