The phone features a sharp, 6.4-inch display with a 1,440-pixel resolution and a 564ppi pixel density.
It also has the same three-camera array on the back as the V40, with a 12-megapixel standard shooter, a 12-megapixel telephoto lens for portraits and zoom, and a 16-megapixel wide-angle lens.
The phone has a USB Type-C port for charging and file transferring, as well as a 3.5 millimeter headphone jack.
The second screen works within a case, and you have to line up the case with the three pins seen here on the back of the V50.
The accessory is useful for multitasking, gaming and photography.
For photography, the second screen lets you preview photos on one side without leaving the camera app on the other. You can also use the screen as a reflection when you capture selfies.
