blue tint to screen?

I have been noticing that all the whites on my epics screen have a blue/grey tint to them. Nothing looks true white. Regardless of the brightness setting there is always a blueish tint to the whites. Is this common with the epic? Or should I run back to best buy for a replacement??
 
I have used two Vibrants and none have had this issue.

Yeah I was thinking it wasnt suppose to be this way...Oh well time to go back to best buy for an exchange...:(

Not to mention that the white color obliterates the battery life. :( Unfortunately, it's not a defect, but indeed reality.

So your saying this is normal for the Epic? Or just that whites in general are horrible on a AMOLED or SAMOLED?
 
I just went to att and checked out the captivate. Every single captivate in store as well as 2 the employess owned all had blueish tints to their screens. Exactly the same as my epic. I'm starting to think this is a SAMOLED issue and not just an isolated issue.
 
Its common! Some people will just get real lucky and say ohhhh no, mine has a pure white screen! And its sadly true, some of us will have the tint, some wont, its a crap shoot. My fascinate has a slightly blue tint to it, when I held it up to the Epic in Sprint while on Google, my fascinate looked very very white, and the epic more blue! Meanwhile when held up to the demo fascinate in vzw my screen looked more blue, and the demo pure bright white??? This is a screen issue that has to do with the color temp, you may have to look through 10 phones in a store to find one with a pure white screen with zero tint, like I said, a Crap shoot!
 
SAMOLED screens need to drive all three subpixels to full in order to create white. So depending on how you use your phone, you can have great battery life or you can have horrible battery life. If you spend a lot of time playing games like Dungeon Hunter or watching movies like Fight Club, the dark scenes help conserve power since the darker the picture, the less the subpixels have to work. But if you spend most of your time surfing the web, and writing emails, the extensive use of white backgrounds will deplete your battery very quickly. Varying power requirements depending on screen brightness isn't an issue with LCD because the backlight is on no matter what the screen is displaying (which is also why the contrast ratio isn't very good since the backlight will cause blacks to look more gray).

The blue tint is probably related to the blue subpixel burning out faster than the others.

From Wikipedia:

Color balance issues: 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.[59] 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.

So it appears that blue tint is more or less on all SAMOLED screens. The question is, how many people even care? My co-worker's Vibrant is so blue it's unsightly to me, but he doesn't even notice.

Thanks for the info. So it seems as if this is pretty normal and "supposed" be this way. It does bother me a little though, I will probably go to best buy and exchange and see how the new one looks...
