I've read on some threads about this, but is this in the new V5 Voodoo kernels out for the Fascinate? I've applied them, but still notice the blue tint on my phone compared to other phones. I just want the blue tint to be gone, thanks in advance to any repliers
Color fix only works at 100% brightness.
so does the voodoo kernels for Fascinate actually have color fix? My screen is still tinted blue at 100% brightness.

I recently got a Fascinate and I've noticed that, compared to my dad's Fascinate, the color balance is significantly more blue on my phone at all brightness levels and is especially noticeable when looking at a primarily white webpage such as google's. While it's probably not something I would've noticed had I not had another screen to compare it to, it has really been bothering me and I'm wondering whether I should try to have it replaced before my 30 days is up (It just so happens today is the 30th day).
In trying to find info on this issue I've come across a lot of conflicting accounts about color balance problems on the SF. Some say their phone has the blue tint while others complain of a yellowish tint. One of my worries about exchanging this device is that the blue tint may actually be preferred or even intended on Samsung's part because according to the wikipedia article on OLED:
Additionally, as 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. This differential color output change will change the color balance of the display and is much more noticeable than a decrease in overall luminance. This can be partially avoided by adjusting colour balance but this may require advanced control circuits and interaction with the user, which is unacceptable for some users. 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. More commonly, though, manufacturers optimize the size of the R, G and B subpixels to reduce the current density through the subpixel in order to equalize lifetime at full luminance.

The problem is there is no citation given for the section in bold so I cannot be sure if manufacturers are actually using this method. It's possible Samsung uses the "more common" method and my device is simply a defect.
Has anyone had a similar experience with their screen?
Can anyone confirm whether this is intentional or unintentional on Samsung's part?
Do you guys think I should try to get a replacement?
tl;dr
My SF has a bluish tint to the color balance, should I try to get it replaced?
Hmm I noticed my replacement Fascinate had a purplish tint (mainly towards the bottom) on the screen.. This was not apparent on my original.. May it rest in piece(s).
Search for the voodoo project(?) on google.
Btw my screen is more blue than my girlfriends even when I have color fix. Not a big deal.

My Fascinate has a yellow tint - very slight at full bright, but rather noticeable when the phone downshifts to low-brightness.
The one at the store was similar, so I didn't worry about it, but the voodoo folks have a color fix. I have avoided voodoo thus far, so I have no idea how effective it is.
color fix only works at 100% brightness.

I am looking for honest opinions about the color change to the Nexus S display with the 2.3.3 update. I have heard very many people complaining and not liking the new color scheme. THis is key to whether I allow my nexus to update or not. If anybody can give me any opinions regarding this I will greatly apprectiate it. Also, what exactly was wrong with the original color scheme to begin with?
I've been lurking for a while now, but I suppose it's high time that I start contributing around here!
I think the update's colors are fine. Breaking it down, the 2.3.2 and below colors were a bit reddish in my eyes. While you couldn't tell for the most part, if you use a program like Screen Filter and get the screen to be very dim, there would be a very purple tint to the screen.
The update removed the purple tint, but a lot of people (the ones you refer to) began complaining about a yellowish tint and washed out colors. The yellowish tint is noticeable, especially when I compare white between the Nexus S and either my computer or an iPhone 3GS. In my eyes, it's not *that* yellow, and the screen overall looks better than it did pre-update. The washed out effect I really haven't noticed, though I do think that after installing netarchy's kernel, the colors do pop a little bit more.
Overall, I'm not a terribly picky person, but I do think that 2.3.3+Voodoo color looks better than 2.3.2 or stock 2.3.3.
Jeff's right. 2.3.3 stock colors aren't bad at all. I actually like it over the purplish colors of 2.3.2. Plus I think the lowest brightness levels have been darker than 2.3.2.

You can't compare your super amoled screen to a computer monitor or an iPhone. When making this kinda comparison, you should compare with another similiar galaxy s phone or N1 that doesn't have the purplish tint issue. With that being said, the reason why colors looks washed out to some after the update is because, before the update most of us was used to the grays being purple so alot of images that had this certain shade of gray would display purple. Now after the update, those images that we're used to looking at with the purplish issue are now all of a sudden displaying it's true color of grays, which causes the images to appear washed out. The update does provide the correct color calibrations. Also keep in mind the these screens are not consistently manufactured the same. So even tho the update provides the correct color calibration, the outcome still may vary depending on the condition of the manufactured screen which explains why some are experiencing extreme yellowish discoloration.

my brother bought a nexus S used few days ago. it was on 2.3.2
on high brightness, the white was perfect white " no yellow tint on it. perfect white.
however on low settings, it used to have pink tint that is more clear on gray colors.
so he updated to 2.3.3, the pink is gone. but now the screen has this " yellow " tint to it that makes the creen looks washed out. the blue not really a blue . its lighter blue, and the white on high setting is like yellow white.
however, he updated the karnel i think with one from voodoo where he can pick between 2 color profiles " forgot the name of the karnel but its in xda "
now the screen is back to how it was on 2.3.2 with its white " no yellowish" and when he pick the color profile for the low settings, the pink is also gone . no more pink on low settings and yellow on high settings. its actually perfect.
i assume if your phone has yellow issue on 2.3.2, then you are probably screwed. as there is no fix to that. the voodoo will only return the white to how it was on 2.3.2
but if your white was perfect and you have a problem with the pink, then look for the karnel, you will lose your pink plus the perfect white will come back agian
I had my Epic since august and now im starting to notice redish tint on all white pages.
I know that Voodoo kernel adds red to blue tint screens for those that was lucky to get blue tint screens to compansate for blue wear out.
Is it possible for someone to make a kernel with blue tint to compensate for pages appearing with red tint?something like cool temperature setting on tv's for those of us that are experiencing blue color degrigation.
Or is this covered under warranty?Sht is deffinetly noticable my google page appears light beige color instead of white and thats with maximum brightness,when brightness is all the way down pages look light brown.
Im starting to think maybe SAmoled's life is too short for 2 year contract,i looked at Atrix slcd and i wasnimressed almost as nice as Epic,i hope Amoled Plus fixes this.
I've had my epic since launch actually 2 now but I don't see any red tints on white pages. I've had many roms and kernels been on froyo dk28 day1 and now cm7. Maybe you faulted screen with voodoo cuz I never installed that mod. Bad screen or bad setting somewhere. Try odin

Nah i never installed Voodoo before.Im on latest Syndicate right now and i do flash my roms properly(with Odin and 4 wipes,lol).
My epic did see some heavy use though because somebody in my house is always on it.I doubt that its Syndicate's fault.I just think its degredation,thats the reason Samsung shipped alot of Galaxy S models with blue tint/cool temperature so over time when blue degrades colors just appear white and blue tint dissapears.
But not everybody bought their Epic with blue tint,my colors were on point with no tint.Im sure im not the only one having this issue,to make it short my screen is not what it used to be.
No tints on the white pages on my.phone.

already did. they refer to yellow tint on the side only.
I have the same issue. My previous sgs2 had a yellow tint on the left side. I send it for repair and got the screen replaced. Now my whole screen is more yellowish, while my previous phone was more blueish (warm vs cold tint). I'm on KG1 now. The yellow left side is as good as gone though.
On 100% brightness the whites are really white, but below 60% the white and grey turn yellow.
I've searched for an app that allows you to change the color temperature but haven't found one. I've found a few that simply turn down brightness levels individually for R, G and B, but that doesn't work. Personally I'd like my phone's tint to be a bit cooler.

On a yellow tinted phone, the whites only seem white till you compare it beside a phone with a higher color tone.. thats what I also experienced.
guess we just have to wait for speedmod colour fix or voodoo color..
Is that being developed? I would be more than happy to donate a few bucks to anyone who can deliver such an app.

Have you tried changing in settings, Screen the 3 different configurations it has?. Try the fist one, i think it has too many saturation but whites are whiter (at least for my sight).
