Samsung has brought the early noughties flip phone into the 21st century with its Galaxy Z Flip smartphone, which has a 6.7-inch flexible glass display that folds down to fit in the palm of your hand.

The screen is comprised of one expansive surface with a bendable centre, while the phone's base structure is made up of two main sections joined together by a thin central component known as the "hideaway hinge".
When open, the phone has a full screen size of approximately 6.7 by 2.9 inches.

The hinge enables the Galaxy Z Flip to be folded down with a "satisfying snap" into the size of a wallet ? approximately 3.4 by 2.9 inches ? so that it can easily fit into the user's pocket or bag.
