SCREEN COLOR VARIATIONS among galaxy S line?

Its strange but noticed that my phones whit coloring looks a little more greenish than my.friends vibrant. And then i compared my captivate to my gfs and here whites r more white colored like my friend.
I don't get it, did a lot if the models come with different screens that display differently?

seems like someone needs a little more research
wait what no the whole entire galaxy s line has super amoled hmm its maybe the tint thats changed a little

A Super ALOMED screen is still AMOLED.
Anyway, just because it is the same model screen doesn't mean there are not variations in the mfg process that could cause slight differences. With the amount of screens that they are pushing out I am sure they are using equivelent components that may not be exactly the same.
Also depending on the allowed tollerances, 2 screen with slighly different temperature ratings could both still pass QA.
Personally my screen is very cold, whites tend to have a slight tint of blue to them. I prefer warmer displays but the SAMOLED is too nice to ignore even if the picture is cold.

It's possible that the screens are going through a rapid break-in process and the screens look different because they have been used different amounts.
Or it could just be differences within manufacturing tolerances.

Well this all makes sense. Mine has a greenish tiny, my gf and frie.d have a warmer orange redish tint and i have a lil blue green tint.
This follows the rgb thing in a way. I think different screen manufacturers favor one of the latter.

That's funny cause the AT&T commercial specifically says "The first and only Super AMOLED screen" or something of that nature....

screen is fine, got mine on launch day,,,im sooooo loving this phone,i was using omnia2....

They may make the screen, but that doesn't mean they make all the materials used to manufacture the screen.

Different materials cause wider manufacturing tolerances. It's not different manufacturers favoring one color over another in this situation.

I really wish there could be a straight answer instead of speculating why our phones are cooler and warmer in color. I mean the screen still looks freakin great, but i wonder if there is a way to manipulate it through software.

I agree. I would love it if phones finally started letting you adjust color temperature like computers.

My screen is also blue. I´m waiting it to go away in time, but I´m really sceptic about it...
It´s easy to test after you download somekind of a flashlight app and use it in the dark, mine gives the same blueish light like those cheap led-flashlights, so definytely not real whites in my unit...

There is no such thing as real white when it comes to light (what your screen is putting out). I would prefer the screen to be warmer, but it is still white.
For more information look up color temperature.

The HTC Desire and Nexus one on Cyanogen Mod both allow you to adjust gamma settings via software. So this can definitely be corrected. All it requires is additional dev magic and a dab of patience.

That's interesting,i hope someone is working on color temperature too.

Somebody else mentioned it but "manufacturer tolerance" is what causes this. It would be possible to make them all exactly the same, but the costs of the device would go up significantly. Usually the difference is so minute that most people never notice.
You see the same thing with mass produced digital projectors and tvs. If you were to take 10 new projectors of the same model and line them up side by side you would find not all the pictures were exactly the same. Due to manufacturer tolerance some may be slightly brighter or dimmer and colors may be a little more vibrant on another.

Blue Tint
Yes, Super Amoleds are coming in all forms of Tint. Some are lucky to get nice warm whites. Other people get green, blue, greenish blue, or even yellow tints.
maybe even pink tint like the amoled on zune hd

Color calibration?

Is there any way to change the color calibration on the display? I want to raise the blue levels because I'm a bigger fan of a cool color tone and the whites on the g2x are more than an off white. (compared to my mt4g with good lcd where whites are bright white)
I have heard about the color calibration hack for the nexus one but I don't know if it'll work on the leaded gingerbread ROM from paul o'brien

If you don't know what I'm talking about go to the color settings on your computer monitor or tv and change from "cool" to "normal". The g2x is more like the normal setting while i like the cool setting better.

I posted a link already. There is a calibration tool in the Nexus One forums that you can use. I don't think the G2x needs it though. Mine looks natural.

I'm fine with all the colors except for white, I'm a bigger fan of a more bluish white like on the iphone.
I'll give the nexus one thing a try but i think a bunch of people who tried it on the g2x it force closed. Not sure about the leaked gb rom though so I'll try it and report back

the flash aborted because it says amend scripting is no longer supported since android 1.5?

I also tried installing both apk's and they both force close when I try to do anything

pretty sure you have to be on cm7 for it to work

Is it just my specific device or are the whites on this phone not really true white but more like off-white? If u compare it to the mytouch 4g with good lcd there's a big difference. Although this device does have truer blacks.

Every LCD is different. Even if the phones are the same model. Mine has a bit of a red tint when showing white but its only noticeable if I look at it next to my Vibrant.

I know different phones have different color tones but I just wanted to know if it was just my device where whites weren't true white because some people have been talking about a yellow or orange tint. I'm expecting a replacement phone to arrive next week so I guess I'll do a comparison when it arrives.

Looks fine to me, but really I'm all about resolution. Colors can vary and sounds can be medium quality and I probably won't notice a difference.

Meaning if you took a number of G2x and put them side by side none of them would be completely identical. So its not just you that has a slightly off screen.

[Q] Screen pinkness (is mine normal?)

Hi all,
Picked up my One S on Monday and, so far, in almost every way it's my "perfect" phone - great feel, weight, crazy slick... just lovely.
However (and why is there ALWAYS an Achilles heel?), I'm really not happy about the screen. Ok, it's pentile, but so was my Desire (AMOLED one) and I never had a single problem with that. It's just this one seems so, well, pink! Not just in white balance, but there seems to be too much red everywhere - e.g. text on grey in Tweetdeck has crazy amounts of red fringing (especially noticeable on the yellow too), and the over saturated colours are almost too much (though not much more than my Desire, to be honest).
(Quick comparison of the screen temps attached)
I mean, seriously, that's not normal, right?
Am I the only person who seems to notice red / pink outlines on everything, am I the only person bothered by it, or am I just unlucky with this phone?
I went to Carphone to swap it, but they wouldn't because their manager was out and because I traded down from the X on Monday (flickering screen nightmare), so I had a play on their display model and I convinced myself the screen on that one was better! But, I'd love a second opinion!
Cheers!

Oh that's really pink! Will check mine when it finishes the first round charging.

I would say this isn't normal. On amoled Displays white areas appear a bit blueish or grey. But this red/pink looks unnormal
Sent from my HTC One S using xda premium

no, this doesn't look normal. But the thin red and green outlines are caused by the pentile-matrix, this is normal.

Just download Screen Adjuster and increase blue and green values a bit and your red screen will be gone

That's a v. useful app! It's definitely taken the edge off (green & blue at +5), but I'll still pursue a replacement as the contrast has taken a bit of a hit now.
(I'm such a perfectionist!)

Well, when I say "see" I meant on their own One S rather than on my screenshot.

I sometimes notice it being a bit pink when the brightness is set low, have you tired using auto brightness or putting it a bit higher?

Hmm. Other than at 100% brightness, it still seems pinkish. I finally get to persuade CPW to give me a replacement tomorrow...

That's looking odd definitely. Let us know if the replacement is better.
I haven't noticed any issue on mine
sent using HTC1S

mine screen is definitely on the warm side of things (meaning the whites are yellow'ish). seeing how One X has a yellow tint issue (different screen manufacturers involved it seems) and you're playing a screen lottery i wonder if One S is the same. slightly warmer screens is not an issue per se but a strong yellow tint definitely effects the overall brightness and sharpness. i would love to compare different units in store to see if One S with cooler screens actually exist.
the pink tint is a straight up defect, however.

This probably won't help you. It won't hurt I guess, but this is something that can be worked out with a software solution. The SGS had something called Voodoo Colors, and I'm assuming that at some point that'll make it to the One S, as it's an AMOLED device as well. The colors changing on low brightness is one of the characteristics of an AMOLED screen.
As a poster above recommended, install that tool and set adjust the values for now. In due time, this'll be worked out. HTC just didnt do a great job with their color profile.

A fix for the yellow-ish display

I really like the phone and think the screen is fine in most areas...but it's very yellow. The whites aren't really whites and, compared to my HTC One, the difference is striking. Yes, I know the One has an extremely cold screen while the Nexus has a warm screen, but there has to be a happy medium here, right? I think this is clearly just a calibration problem that can be fixed with a software tweak, so does anyone have any ideas? It's literally the only thing I'm not happy about.

Maybe it can be adjusted for in software, but I don't believe this is just a calibration issue. I also don't think it's color temp, precisely, because that should be either bluish cold or reddish warm, not urine yellow (sorry, best way to describe it). I've seen this on many devices over the last few years, from ASUS Transformers to iPads to the Nexus 7 and Nexus 10. The only device I've bought where I didn't have at least one with a yellow screen was my Nexus 4, and I'm pretty sure I was just lucky the first time out--plenty of people complained about this on their Nexus 4s.
I think it's some kind of manufacturing variability, with the intended design specs (and software calibration) to have truer whites and deeper colors (washed out UI colors go along with the yellow tint). Personally, I can't accept it--the problem also shows itself as a lack of contrast in UI elements, such as the browser address bar against the background gray, or text fields in Hangouts. On the yellowish displays, there's almost no contrast, and so the fields can actually be hard to make out sometimes.
Thing is, if you never have two devices to hold side-by-side, then you may never notice the issue. You'll just think that colors are washed out, because that's more obvious by itself than the off-color whites.
I went through four iPad 3s before getting one with true whites, and more Nexus 7s and Nexus 10s than I'll admit to. I just hate it, personally, and honestly the Nexus 5 hasn't been so great so far that I'll go through the same number to get one that's acceptable. I have a replacement on its way (my audio output is also a bit distorted), and if that one's the same then I might give up on this year's Nexus and get an LG G2 instead.

Interesting. Yesterday I was actually angry and posted the phone on Swappa. Today I've been much nicer toward the subject. But if it's really due to the manufacturing process, I might just swap it for a Moto X. Either way, I'm not sure. I still need to decide.

Best thing would be to wait for the dev's and see what they come up with. They did great with the N4, so I'm hoping it'll be the same on the N5. I do think the display is incredibly warm. Having it side by side with my N4 is striking.

Yes, thanks, you're right--color temp does go through yellow as it gets warmer before getting to red. So, thanks for the correction.
That said, it's not a _consistent_ thing, or at least hasn't been in the past with other devices. I have a Nexus 10, for example, that is much colder (with white whites, not blueish, so I'm calling it right in the middle) than many others that I tried out side-by-side. It also seems to get better with given devices as the manufacturing process goes on--for example, it was a problem early in the lifecycle of the iPad 3 but then became consistently over time (if forum complaints about it can be taken as evidence).
So, personally, I think that it's simply very difficult to make consistent LCD panels with these resolutions and at these price points. Perhaps someone like LG does a better job of quality control in making their higher-priced G2 than they do screens for their Nexus 5; I haven't read about this being a problem with the LG G2's screen, which I think is similar technology.
Anyways, it definitely makes an impact on the quality of the experience. I might be much more sensitive to it than others, and some people might actually prefer their screen warmer--although I wonder if they would if they hold it next to a screen that has truer whites. Really, the difference in contrast is what's most striking, to me at least.

Oh, and, I think you're right about the brightness levels as well-it does seem to get a touch better when the screen is brighter.

this also happened with the iphone 5s..it was fixed a few weeks later..our phones have only just been made and the glue takes on average 2 to 3 weeks to dry completely and then become transparent..relax

Here's a really good article discussing what's going on here: http://www.eizo.com/global/library/basics/color_temperature_on_an_LCD_monitor/
Look at about 3/4 down the page, they have examples that demonstrate what we're seeing quite nicely. Not only are whites more yellow, but to my eyes colors wash out the warmer the display.

Unfortunately, I don't think this is the same as the glue issue. That's typically only on parts of the screen, and I've seen this too many times on other devices where out of the box one is terribly warmer than another and it never resolves.

You're right , when it's a glue problem usually there's just spots, not a solid yellow tone over the screen, so what can we do? try to exchange the phone, are there nexus 5 with colder screen or are they all so yellow?
I had a galaxy nexus with a terribly yellow screen, let me tell it NEVER got better , even after months of use :crying:

This video shows the difference between the N4 and N5. Wait until it gets to the browser speed comparison, you can see the screen is yellower on the N5 and the UI contrast is less. Note that the apparent difference on mine is much greater, so either this is variation or the video mutes the difference.

Comparing my Nexus 5 by eye to my calibrated (sRGB, 6500k white point) monitor, the Nexus 5 has a very slight blue push. The Nexus 4, however, is INCREDIBLY blue. Like 9300k blue. If you're used to the Nexus 4, the Nexus 5 will look yellow, but it's the Nexus 4 that is out of whack in this case.

Return it. No yellows here.

LOL is anybody else using comfort view 100% ?

Im using comfort view round the clock because the yellow stainig seems to round out the natural blue tint of the display. Not sure what is more color accurate but my eyes adjust easier to the yellow tint. Lol! Funny i didnt think the cold hue screen would bother me.
Do you like the screen? :laugh:

I use the comfort screen all day too

Me too! Its pleasing to the eyes.

Same here, switching now back to normal seems to have a blueish tint to it maybe the colours aren't calibrated right from the box...but comfort view just seems so normal now.

LOL cuz your eyes adjust!
try sitting at a color-accurate monitor for a few hours or close to your tv then switch or compare side by side to another screen! if i go v20 i see it blue and feel my eyes need to adjust to the white. if the comfort view is on i feel my eyes adjust more quickly. if i view either without comparison they look normal but switch one to the other and comfort view looks more normal to me even though i know they intentionally mess it up for yellow!! haahhaa...
srsly tho, i dont think their panels have so much variance that you got accurate one and i didnt... but maybe that would sux. once again, only visible in comparison!
glad you like it! it's nice phone. not sure i understand the fetisch with locked bootloader but hey... whatevz. i\ll be happy if we oreo in april.

100% comfort view all day! Lol! Yes, the natural color calibration on the v20 feels cooler than usual but it's quite accurate in fact. The reason we feel this way is due to the immense number of AMOLED display panels on the market these days, which by nature, are MUCH warmer than any other panels. Not to mention over-saturated in their colors.
That also begs the question, is the color-accurate monitor, or TV you're using, an AMOLED, plasma or IPS LCD panel? haha (;
Either way, I enjoy comfort view too!
