i recently noticed this on my 9900, and i have no idea whats with it. the phones about 5 weeks old, and i plan to ask my carrier dealership as soon as i can. theres a small line of purple pixels on the left side of my camera screen when im taking pictures and video. it only appears when the camera is in use. i took a screen grab of it, and im including it
I think it's screen light bleed when the screen is dark. Try looking at a black image in the dark and see if it produces the same results. I just tried mine and it doesn't do it. Maybe not that great of an assembly then. You can always ask for a new phone which means they'll give you a refurb. =/
