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.

Well thats why I want to change the color settings because the high levels of red in the whites are really bothering me.

[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.

[9020t]Why is the color so different?

I currently is using a 9020t nexus s and I realize it has the washed out problem like many people even after I upgraded to OTA Android 4.0.4. I managed to fix the problem by rooting and voodoo color. However, recently, I was helping my friend to upgrade his Nexus S from 2.3.1 to 4.0.4. Immediately, I noticed that his color is much different and it is not wash out at all even after the update. The grey are darker and the color is darker in general. Do you guys know why there is such a difference in color even though we both update to the same stock rom and kernel? I am just curious. Thank you for the help in advance!

Many different batches of OLED based displays tend to look different. One display may look green, one blue, another accurate but saturated, as has been my experience with others phones. Whether it is different materials or material quality, hardware calibrations or manufacturing machinery we will probably never know.
Slight blandness is probably more noticeable due to the pentile screen on the Nexus S AMOLEDs when different settings are used as opposed to full RGB arrays in "xxOLED Plus" displays.

Thank you so much for the reply, so if I install the same rom/kernel and used the same setting on the voodoo color, both phone would look very similar ?

No, but the same phone will between ROMs. Voodoo would be relative to what is already shown and not an absolute change that would work between phones. However, they would likely look similar. I've not played with it myself (i have the LCD so I can't) though.

You are right, I tried install the same rom and set it with the same Voodoo setting, it is just not quite the same. I also notice that the one I have is brighter than my friend's in the same setting. Upon closer inspection, I realized that mine was a remanufacture model. Could it be possible that mine was actually a SLCD instead of AMOLED? Thanks for the help.

If voodoo colours works, it's amoled.

[Q] yellow tint with CM,normal color with ColorOS?

As the title says,MY OPO is suffering from this.Flashed CM or any roms aosp/cm,I found my screen color is normal for the first seconds of booting,then the color of the screen turned to yellow.yeah,it's sooooo much yellow.even I configured in the display settings,it's no use.I flashed back to ColorOS.then the color turned normal,beautiful screen back.
so my question is why this happens,if it's intended to do like this,why?then do you guys have this problem?
regards.

It's by design in the CM ROM and a future update will allow the color to be adjusted. The warmer tone is technically more friendly for text viewing and skin tones, etc. but people don't tend to like it as they are used to a cold white. Properly calibrated displays are always warmer, however, because they tend to reflect a more natural light that mimics the sun.

I just posted the same question: http://forum.xda-developers.com/oneplus-one/help/oneplus-display-color-temperature-white-t2801107 probably should be deleted, I didn't see this thread.
But, anyway.. is there any workaround for CM and other custom roms? This yellow screen is annoying, so annoying...

Franco kernel will have the necessary adjustments passed into userspace soon enough, just FYI.
From the man himself, "We already have color control interface in the Kernel by supercurio, I've asked him to expose the controls to userspace. Once that is available I'll add the code to the app."

i had the same issue, when i was on cm the whites are so yellowish i thought i had a bad screen. but when i flashed color os the
yellowish tint was gone. so ya its a software issue with CM
