Screen issue

Last night while using my phone in the dark, the brightness set down low, I noticed on sites that were darker themed that there is an odd anomaly in my screen. There is a line (that reminds me of a hair, maybe an eyelash) that only shows when the brightness is low. I was able to take a picture of it with my girlfriends G3, though it's much more noticeable when you're using the phone, as it's stationary when you scroll.







This is my first Super AMOLED screen in a while, but I don't remember anything like this before.
