Motorola was once owner of a trademark for the term flip phone , [16] but the term flip phone has become genericized and used more frequently than clamshell in colloquial speech.

In , Motorola introduced a different kind of flip phone with its Backflip smartphone.

Use of the swiveling form factor has similar goals to that of the slider, but this form factor is less widely used. Sony Ericsson Wi , a swivel phone. Motorola V The Motorola Flipout , a swivel phone. Some implementations, that do not use the sagital axis, are presenting in phones like Nokia and Oppo N1 , with twistable componentes: a keyboard, and main camera doubling as a selfie one , respectively.
