Looking at that image, there seems to be a mic on the corner right side of the device, which, at least if you hold phones like I do, you'll probably cover if you hold the phone portrait mode in your right hand (Maybe even in the left hand as well), or hold it in landscape (With one finger on each corner to hold it). If the guy in the picture was holding it right handed like he is with his left hand, he'd be covering it. Perhaps they want you to cover it? Is it not a mic? Is it just bad design?
