On my HTC M8, there looks like a small color blotch or something right around the bar with the 4 icons are at. It's faint but noticeable when there's black on the screen or when I'm about to load a movie.
Faint or not it's a blemish on it, can HTC replace it since I'm out my return period on my carrier.
