Designer Jon DeGorsky represents a concept of a mobile phone, manufactured under the brand name of Nokia. The device became known as M31 and the remarkable fact is that, in addition to the unusual shape, the device has two touch screens.
The two screens become visible after opening the slider. On the external screen there are displayed the contacts, the functions of an Internet browser, e-mail, messages, games, calendar, and the options. The inside screen of Nokia M31 provides a virtual numeric keypad, control panel interface and the interface for the letters. In addition, the back of the device has a digital camera.
