So I don't own a captivate, but I do own another Galaxy S phone, the Vibrant.

The vibrant forums, people aren't really responding to the blue tint. So i'm wondering if you guys on the captivate have noticed that everything that should be white, such as a white broweser window, is actually tinted blue?

If this is your first smartphone you won't notice probably, but if you own a prior LCD smartphone, try putting your screens next to eachother. Does the Galaxy S look blue?

Just wondering if I have a bad unit.

thanks
 
Yeah, they went with PenTile tech to save money. :)

I'm reading online that the blue tint may be temporary, and if your phone has it, you are actually lucky. Because, I guess the BLUE leds die out really fast compared to the rest, so Samsung on purpose made the screen to over display blue, and as time goes on, the blue will die to a yellow. So if your phone is more blue today, it will last longer tomorrow.

I don't know how true that is. Read it on some forums, that is what wikipedia says also.

Samsung tunes all of their displays (TVs and all) towards the bluer end of the spectrum because it gives the display a higher apparent brightness because our eyes perceive bluish white as being brighter than yellowish white even with no actual brightness difference.

Not my eyes, my eyes see blue white as being darker and almost gray, while yellow white is much brighter like the sun.

If there is a blueish tint to my Captivate, I neither notice it nor am affected by it, and regardless the issue would be far-outweighed by both the huge benefits of this phone, as well as much-bigger issues that need to be addressed.

If your horse has a broken leg, you don't complain about the way it smells.

you are lucky

depends on how bad it smells :) (kidding)

If I look and really compare to bright whites I can notice it, but I don't mind it in the slightest. The color spectrum and the black levels are so much greater than my old iPhone 4 that im happy. I do notice with a few co workers iPhone 4's the pixel density and the true whites, but am far happier with the black levels than the pixel density

also, i just pulled off my back cover and the battery date is 07/04/2010, i dont see any posts about this date, maybe im special

p.s. battery date info is in this very similar thread: http://androidforums.com/samsung-captivate/152896-screen-tint-newer-vs-older-captivate.html

maybe a mod could just merge em?


EDIT:

well, if your comparing these forum just look at the background. It's already has a tint blue. I was using my captivate under this forum and noticed the blue. now im on my pc and it has a blue tint in the background.

are you talking about the actual blue background on the default skin for this forum? if so that is not what anyone is talking about, the first post in the thread linked above will show you exactly what people mean

Well a possible answer is that, according to something I heared in one of my electronics classes, there isnt any such thing as a TRUE white LED yet. Many "white" LEDs have hits of other colors, such as pink, yellow, and blue.

That seems to be confirmed by an article here:
What Is True White LED? | eHow.com

Since the AMOLED is a type of LED, maybe this could a possible explaination?

^^^ there is no white LED in AMOLED :)
it is RGB (red+green+blue) when all 3 leds for one pixel fire up, the colors mix and you get white color. The bluish tint might be related to Pentile RGB technology in this AMOLED. I do not notice blue tint though on my Captivate, and I got one of the first batch ones (bought at release date, first at my store).

Really? So then, for example, you think a car with standard halogen lights looks brighter than one with HIDs? Even when the halogen lights are on their brightest setting, to me the HIDs still look brighter because of their bluish-white tint.
