The single OLED display of the Mate X actually serves triple duty. When the device is folded, you essentially have a dual-screen smartphone, with the second display on the rear allowing you to shoot selfies with the main camera or to share what’s on your primary display with a person on the other side. Open up the Mate X, and you get an almost square (but not quite) tablet that has minimal bezels on three sides.
One of the sides is reserved for a thicker grip section that houses the three cameras, their accompanying flash, and a push-button latch that secures the folded tablet in a closed position. This approach keeps the thickness of the main chassis down to an impressively thin 5.4mm. Even when folded, the Mate X measures just 11mm in thickness, thanks in large part to the fact it has no gap in its fold. That’s the inherent advantage of folding a screen around the outside rather on the inside: you don’t have to fear creasing the beautiful display.
