I just notice my screen is not "full screen". I could have sworn it wasn't like until this morning. I just noticed there's a small border all around my screen as in the screen does not go all the way out to the black plastic. The size of the border is about the thickness of a credit card, and it's all around the screen. I don't recall it was like this before. Does anyone have this or is it normal and I'm just imagining? Thanks!
