foldable smartphone

A foldable smartphone is a smartphone with a folding form factor. While folding designs have been used previously in clamshell or "flip phone" models, the term "foldable" now generally refers to a newer style featuring flexible displays. Some variants of the concept instead use multiple touchscreen panels connected by a hinge. Concepts for such devices date back as early as Nokia's "Morph" concept in 2008 and a concept presented by Samsung Electronics in 2013, which was part of a broader set of ideas using flexible OLED displays.
