That's probably not the width of the object: It's a smartphone seen edge-on, so your "width" is actually the thickness. Well, mostly; the left half of what we see of it is probably (judging from the differing shades of black) a foreshortened view of the back of it, and the right part the edge. It has the rounded-rectangle look of an iPhone; did they have a single camera lens in the upper left (head-on) / right (from the user's side) corner with a silver-ish border around it?
