A hinged cellphone that is more compact when closed. The cover "flips open" to reveal the screen, keypad, speaker and microphone. Also called a "clamshell phone," the flip phone is a basic cellphone without Internet access. See feature phone.

Back With a Flair
In 2020, the Samsung Galaxy Z Flip (shown here) and the Motorola Razr clamshell smartphones debuted with folding screens. Unlike the flip phones of the past, these devices are state-of-the-art and considerably more expensive. See Galaxy Z Flip, FOLED and smartphone. (Image courtesy of PCMag.com.)
