Serene is a mobile phone produced as a joint venture between Samsung Electronics and Bang & Olufsen.

It is not the first time that Bang & Olufsen has worked with other companies to produce mobile phones.

The hinges have an internal power assist motor to help open the phone completely.

The handset was designed so that for standard use the screen is at the bottom of the phone, and the keypad is on the half that flips out.

The camera is located on the side of the phone on one of the hinges which makes taking photos hard.
