Because some people are bothered by a noticeable blue color cast. I wouldn't call wanting passable color accuracy "anal".
[Vibrant General] androidmonkey:
like I said, turn up the brightness and turn off power saving mode. Your whites will be white.
[Vibrant General] blanked:
You know what that sounds like? "You're holding it wrong"
[Vibrant General] androidmonkey:
How is that? Adjust the brightness of a light in your house. See the colors around you? They change, brighter the light, the brighter the colors, the darker the light, the darker the colors.
[Vibrant General] SamsungVibrant:
You are making an assumption that people didn't already try something that is common sense. Of course I increased the brightness in both the settings and the browser, and power saving mode is off.

You know, you may not know how severe the blut tint is, because your phone doesn't have the problem, however some people their phone is shockingly blue. I've compared mine to several vibrants, and my screen is very grayish blue, even at the highest brightness it doesn't look as bright because of this issue. It causes not only whites to look off, but other colors also.

Today I walked into t-mobile, put my phone next to the display, adjusted the settings exactly on both, and my screen was strikingly blue. while the display model was showing warm bright whites.

Obviuosly i'm not the only one with this issue, even some reviews from tech sites have commented on some vibrants looking blue.
[Vibrant General] tariqgibran:
The Vibrant I just received today has this exact same issue and it's not subtle in the least. It's going back!
[Vibrant General] temperbad:
No blue tint here ..
[Vibrant General] androidmonkey:
For those with this problem, are you viewing the phone at an angle when seeing the blue tint? I see a blue tint when viewing on the left side angle. On my Macbook Pro, I have a yellow tint when viewing at a side angle.
[Vibrant General] lp894:
I don't know if this has been posted or not but it's from wikipedia. granted wiki isn't 100% accurate but since Blue OLED's have a much shorter life-span than green or red, it makes sense:

"...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..."
[Vibrant General] androidmonkey:
@ip984,

Good info. Regardless, these screens are the best out there. As for complaints about color accuracy, the phones are not meant to be used for professional photography. But if you are not happy, return it.
[Vibrant General] tariqgibran:
Nope, when viewed straight-on. I sent my Vibrant back for a replacement.
[Vibrant General] hot_soup:
The blue tint was the first thing I noticed on the demo unit at my local AT&T store. So some people have this problem and some don't. It may be a property of OLEDs and it may be on purpose by the manufacturer.

Now the question is: is there any way to adjust the tint or color temperature?

And how long does it take for the blue to fade away naturally? I don't know about you guys but I've never had a phone for longer than a year and I don't want to spend half that time waiting for the color to equalize.
[Vibrant General] SamsungGalaxySVibrant:
no way to adjust the color temperate of the entire phone yet that I know of. But if you go into stock video player, you can adjust video playing to warm tones.

but the rest of the phone is still blue :(
[Vibrant General] os2baba:
Compare it with the iPhone or iPod Touch

For those of you who are not seeing the problem with the brightness set to max and the power saving set to OFF, can you compare it against the iPod Touch or iPhone if you have one? Mine seemed that the blue tint was off, but then when I set it next to my iPod Touch, I can clearly see the blue tint. And it's really annoying since the whites look duller.
[Vibrant General] xhuix:
I compared my 2 Vibrants. One has blue tint and the other one does not.
[Vibrant General] rocketpaul:
I have a blue tint on my galaxy S, will it fade naturally or should i go and get a replacement?
[Vibrant General] SamsungGalaxySVibrant:
This is the million dollar question.
[Vibrant General] rocketpaul:
I couldnt risk it, so they are sending me a replacement tomorrow. Fingers crossed it hasnt got the same problem.
[Vibrant General] SamsungGalaxySVibrant:
please let us know if your new replacement vibrant has the same blue tint.

thank you!
[Vibrant General] silverwolf0:
I just got my vibrant and I did not notice any blue tint at all. The blue tint I had noticed before on youtube videos, I rewatched again and did not see them anymore either. My conclusion is that since my computer monitor is set to warm and since most colors are washed out a bit but comfortable to view, the highly saturated colors of the vibrant made me think everything had a blue tint. The UI in fact utilizes a lot of blue for menus and text, and of course Avatar is excessively blue no matter what. Also, lowering the brightness dramatically reduces the color saturation but contrast still remains good with no leaning towards any color, other than the dingy look that white exhibits which is a given at lower brightness.

I don't have an eye for this stuff and am changing my mind constantly, but so far any tint issues haven't been apparent to me since I finally own one now, and its not because I'm coddling the phone as I have a history of complaining about phones right from the unboxing and onwards.
[Vibrant General] floepie:
So, I really hate this about the phone. I suppose for some, white balance doesn't bother, but for me, the colors are very off. Here's what I've done so far. I ordered a replacement from T-Mobile. I then took my 3G iphone and the 2 Vibrants and photographed them with my DSLR with RGB histogram on display. I held exposure constant with manual adjustments as well as the distance of each screen to the lens. I manually set the white balance for the flashlight app on the iphone with brightness maxed. So, the RGB levels were set to identical peaks as the iphone becomes the baseline. Then, I photographed each of the Vibrants with brightness maxed and power saver mode disabled (this makes more of a difference on a white screen than brightness levels!). Not surprisingly, the red levels on the vibrants were quite attenuated compared to the blue and green levels, which were virtually identical on either of the Vibrants. What did surprise me was how bright the 3G iphone is compared to either of the Vibrants. It was significantly brighter as revealed by the histogram (peak further to the right). So, not only do the Vibrants seem to suffer from red levels when compared to blue and green levels, the screen's brightness cannot match that of the 3G iphone.

I then visited a few T-Mobile stores in the Midtown area (all within one mile of each other) to see if their floor models were similar to mine in terms of the blue-green push. Sure enough, some were ever so slightly better (warmer), and some were even ever so slightly worse (cooler).

My take is that these Vibrants are more similar to each other than what is reported in these forums. And, the blue-green push is significant when compared to the iphone, which I regard as having a similar color temp to most other mobile phones.
[Vibrant General] androidmonkey:
Post your results.

Fact is, some people will not be happy, specifically people who expect perfection. One of the main selling points is the screen and everyone I show it to loves it. I dont show them a white screen and tell them "Look how white the screen is" I show them the Avatar movie and their mouth drops to the floor.

I'm not saying this issue cant be corrected or lessened, its just not that big of a deal to most people. If this were a computer monitor, you would be using a calibration system to get optimal results. This is a phone....
[Vibrant General] Jayrod1980:
Call me anal but this is my fourth vibrant. I had a washed out grey blue hue to my first one but otherwise it was fine. Second had a stuck red pixel right in the middle of the screen. Another had a messed up bezel. Checked 3 phones in the tmo store to finally get one with a screen that looked right. Now my phone has beautiful warm whites and the screen and everything else is perfect. Even with those issues, I love this phone and I'm sure my issues are just me being anal. Prior to that, I've never returned or even complained to tmo in the 7 years I've had them. Tmo store was amazing btw in dealing with such a picky customer. By mistake I put my sim in one of the ones I was trying out, and made the phone "used" by doing so. Oops, but they still kept helping me, even after burning thorough that much of their inventory.

If the phone is too blue for you, take it back and ask to see a complete different new ones. My tmo store was fine with it, yours should be able to help.
[Vibrant General] floepie:
Oh, no doubt I'm the strange one. Most people are oohed and ahhed by the overly saturated colors and would never even remotely detect any sort of green-blue push unless shown another phone like the iphone alongside. Any TV showroom worth its weight in salt maxes out their TV's saturation to unrealistic levels, so the average person is not one to ask. There does seem to be a segment of the population which may be more sensitized to proper color temps. And really, the color temp on this phone is dramatically different to most any other phone out there, and we're not speaking of brightness levels. That said, because the black levels are so deep on this phone, it really does make it a joy to use despite the odd colors and almost makes up for the cool temps. I chalk this white balance issue up to the use of the new screen technology in the Galaxy phones, and perhaps it's just something that needs to be improved in newer versions. But, clearly the initial impact of the screen does draw the WOW factor for most everyone.
[Vibrant General] androidmonkey:
Yea, im sure the technology will be improved, unless something better comes along and SAMOLED is ditched. You are right about the black levels, they are amazing. Sometimes I cant tell if my screen is off or not.
[Vibrant General] hot_soup:
At first I was very worried about the blue tint but I've now had my phone for two weeks and I am very pleased with the screen. It's really only noticeable when compared side by side with a LCD screen.

The colors are extremely vibrant and very viewable in sunlight and white areas on the screen really do look white when you're using it.

If you are considering buying this phone, don't let the "blue tint problem" be a detractor.
[Vibrant General] RickCain:
My replacement Vibrant had this problem and it was exchanged. It would have been one thing if it was "slight" but even my status bar text seemed way off (color wise).
[Vibrant General] SamsungGalaxySVibrant:
How is your new exchanged unit, no blue tint?
[Vibrant General] Jodiuh:
Registered just to mention that I find the blue tint on the epic and vibrant's I've seen quite distracting. Various sites I visited, like hardforum or engadget looked completely different than on my Droid 2...and not in a good way.

That said, I've seen images of a Fascinate next to an X and they look almost identical w/ regard to white. Hopefully this is a case where we can receive a "white" screen if given the blues at first.

FWIW, I notice this on my Zune HD and have seen it on the Incredible. Except that they tend to favor red, so dimming the Incredible's screen to the lowest setting resulted in a "bathed in pink" view.

I no longer have the Incredible, but upon return I did see a clerk's Incredible and it had a very slight green look to it. Still not white, but tolerable IMO.

As for the Zune HD, I returned 2 of them and now have one w/ a very mild red tint. It's still there, but not quite a big deal. Not quite relating to the tint, but all the HD's I've seen have a horizontal line going across them that can be noticed when watching movies. It comes and goes, but it's on every single one of them. Pretty distracting to be honest.

Sure these OLED's might be black, but they can't do white, suck down the battery trying to, over saturate and mutilate any site w/ color, and display text that resembles an old dot matrix printer.

Why couldn't this phone have had a retina display and an all matte bezel w/ proper 512MB ram, working GPS, and no funky file system?

...makes me wanna go back to my Razr and give up on these "smart"phones.
[Vibrant General] smashpunks:
before you bash the phone you should try one. Every white is different. Hell the computer screen im looking at right now is like a brownish white, some are way white, some are dull white, off white, bluish, nexus had a purple tint.

I think you all are psycho over this slight blue tint. Most whites on phones are slightly different shade. Get over it..
[Vibrant General] AlexSochi8:
Maybe that's the secret to avatar looking soooo good on this phone... The blue ppl are even bluer lol
[Vibrant General] billa:
LMAO!!! that was a good one .. this phone seems to have been mode for this blue man movie ... joke aside, mine has an noticable blue tint too and I'm going to exchange it or return if they cant fix. Hell im not plucking down $500 bucks for a blue-ish screen. Those of you who want to live with your blue screen, good luck ... perhaps the G2 might be a better choice ;)
[Vibrant General] dorsai3d:
I did some research on this, and it actually has to do with the AMOLED panel technology. Because the blue is one of the hardest pixels to create, and the shortest lived, it had to be bigger to balance out in the long term with these displays. I could go into a nice long technical explanation, but not from swype right before bed. Long story short, AMOLED screens are often designed with a somewhat blue bias at the beginning to account for uneven wear rates (this can also explain the damned pentile matrix). There is also some variance in manufacturing, especially with the low supply/new panel combination here.

Theoretically, the blue tinted screens will, over time, self correct and possibly even last longer.

If people are really interested in hearing an engineering standpoint on it, shoot me a pm.
[Vibrant General] SamsungGalaxySVibrant:
well most of us have read the information online that talks about blue led dying faster. so if the assumption is that samsung made the screens even more blue, to compensate for the blue that will die off, then my question to you is this. WHy aren't all samsung galaxy s phones suffering from blue tint? Some people are lucky and don't have it, some people do have it.

makes no sense, seems to be inconsistency in manufacturing. I also doubt they over played blue on some phones while leaving others behind.
[Vibrant General] Jodiuh:
Verizon store had 2 on display. One looked white with a slight red tint when brightness was lowered all the way down and the other was bathed in blue. The one I got has the slight red tint and I'm OK with it.
[Vibrant General] dorsai3d:
Well, fun that you ask that. The Super AMOLED screen in these phones is not just the bleeding edge of display tech (with ask the quirks that that implies) but it is also relatively new waters for manufacturing technology. There is already some variance inherent in the way that oleds are produced, but if samsung does it the way I think they do, they're using a sort of almost screenprinting/microstamping technology to apply the actual organic compounds on top of the thin film transistor layer.

Eventually we (engineers) hope to perfect a more accurate/reliable inkjet type manufacturing process, but until then, we have to deal with the growing pains of a bleeding edge technology, even if it is mass market.
[Vibrant General] billa:
Ya well, have the "engineers" perfect their bleeding edge and don't sell me a $500 phone with blue tint that's the bottom line cuz it sucks! In fact I went to 2 different tmo stores today checked out their demo phone compared to mine and they both had noticably less blue-ish tint, though not perfect. Exchange time!!! :)
[Vibrant General] the3dman:
You cant blame Samsung for this! It is just the nature of led's as someone said earlier there is no such thing as a true white led. Also the reason for some people having issues and others not is caused by the manufacturing of the led's. Led's are supplied in batches and no two batches are exactly the same color wise. The machines can only make so many in a batch before having to stop to restock the machine with more supplies, when this happens the machine is not capable of perfectly matching the color of the previous batch. To do that all the supplies going into the machine would have had to come from the same batch from the company that provides those supplies which just like the led's there is a slim chance of that. Most led makers get their supplies from multiple different places.

Hope this helps.
[Vibrant General] SamsungVibrant:
Really no such thing as a true white led? Can you provide proof, and no wikipedia is not proof. Show me something, something that says white LED's do not exist. Show me.

[Vibrant General] billa:
Nobody's looking for white led's just a decent looking display with nice warm natural colors. Regardless where the screen comes from the OEM should calibrate it after the final phone assembly. Or another sensible solution would be to include a calibration app so that users themselfs could adjust it to their personal preference.

The argument that the blue is oversaturated and should fade in time is pittiful, we need a calibration app for a great device like this!!!

Having said that, got mine replaced today and it's only a little bit less blue-ish. The Tmo rep's personal Vibrant phone had a nice warm white-ish screen. Well... still dissapointed :(

Ok lets sing this together ;)

I mean really , "blue tint" , come on t-mobile and samsung , how do you expect the phone to function properly with "blue tinted" screen ....

COME ON !!!!!!!
[Vibrant General] dezvous:
Seems like it depends on your brightness setting.

I only ever use the quick brightness feature on the notification bar and at full brightness my screen looks incredible. At lowest brightness it looks just fine too, perfect colors. On the second to lowest setting there's a definite red tint but only on this setting. Doesn't bother me at all since I never use this in between setting and it's only really noticeable if I'm looking for it. It's the only setting that has any kind of color tint, it's strange and almost makes me think that it could be fixed via firmware since every other setting looks fine.

That being said, it is a literal non-issue for me, but that would kind of be a bummer if it was tinted on every setting or say the lowest, middle, or highest setting.

EDIT: Really weird, just tried to reproduce the issue on that setting again and it doesn't seem to be happening anymore. Not happening on any setting actually.
[Vibrant General] Jodiuh:
Out of the 6 Fascinates I've seen, only 2 had the blue screen. It's on every brightness level and its very, very obvious.
[Vibrant General] SamsungGalaxySVibrant:
doesn't depend on brightness, brightness improves the appearance, but nope, if its blue, then its blue.

Can't believe that no-one in this thread has heard of the i9000 voodoo kernel by supercurio (should be ported to vibrant soon if not already?)..

Supercurio noticed this blue tint and has been experimenting with colour/brightness controls for the samoled.

In his voodoo kernel for i9000 he has implemented a new super low brightness mode and also a colour adjustment to fix the blue tint (in testing phase, only applies at 100% brightness in the current kernel, but after using it I noticed the blue tint for the first time. He also noted that samsung had set the blue level in the kernel like crazy!). He's also made some changes to the video player modes.

[Vibrant General] SamsungVibrant:
thanks ;);););););)
[Vibrant General] SamsungVibrant:
where does he talk about the blue tint, i can't find it anywhere.

also if samsung set the blue level in the kernel like crazy, shouldn't all these phones have the same blue tint. Unless some phones have different kernel settings, but that makes no sense, I think this is a hardware variance amongst different handsets.
[Vibrant General] frankwhitten:
I don't think you bothered to look past the front page of the Project VooDoo website. If you bothered to hit the link titled "Color" below the red droid figure you would read, "Color Temperature adjustment:

The Galaxy S screen is great, but it’s blueish. Fortunately, this is not a hardware limitation and Voodoo color restores a standard color temperature to get rid of the blue tint on every display."

Then there are examples of the blue tint right below this statement:

VS.

Please put forth a little bit of effort before proclaiming that you "can't find it anywhere" when it took me less then 30 seconds to find the information.
[Vibrant General] Mark271:
That is awesome news.
[Vibrant General] SamsungVibrant:
Excuse you and your attitude, thanks for finding it for me, but no need for the attitude.

Also the statement that the Galaxy S screen is great, but blueish, this is a blanket statement. Not all Galaxy S screens are blue. Some of these phones do truly produce rich warm bright whites. I've compared my vibrant to a bunch of Vibrants, captivates, epics, and fascinates, side by side. Not every one of these phones suffers from blue tint, so obviously I'm not buying it when people say "oh its a normal artifact of super amoled." If it was a normal artifact, then every single galaxy S would have blue tints, yet that is not the case. I think it is a hardware issue and quality control, not kernel based.

it also appears the photos are simulations, it would be great to see real photos of how voodoo color fixes the problem.
[Vibrant General] billa:
Of course it's poor quality control in manufacturing. The Voodoo color fixer only works on the original Galaxy S not the US versions. So had mine replaced 3 times before getting a decent not so blue-ish one. I don't think there's anything wrong with being picky especially on a high end device like this. Good luck to all :-)
