Do you have the Pebble Blue GS3? Just wondering if that might have anything to do with casting a blue tint thru the Gorilla Glass display. Mine is Peb Blue, but I haven't noticed any blue tint in the display. So you're only noticing it when the 'screen is off', and the display screen is dark (black)?
Btw . . I remember reading, recently on some thread here, about a GS3 user who had contacted the Samsung (International CS, I think), to ask them specifically about why his first GS3 had, what appeared to him, a blue tint to the display, and why his second (warranty replacement) GS3 did not.
I think he said that he was told ? it's just a location specific Samsung manufacturing glitch, effected by a slight difference in display (Gorilla Glass 2?) materials ? resulting in some GS3 displays having what appears to be a blue tint, like you're seeing on your display screen.
Not sure if that's the case, or if it's been verified elsewhere, but it's what one member here reportedly was told by, (again, I think it was) Samsung CS.
Anyone else read that post?
