Clamshell Phones

Clamshell phones, also known as flip phones, are mobile devices that feature a hinge design, allowing the device to fold in half. When closed, the keypad and screen are protected, and the compact design makes them easy to carry. To use the phone, the user flips it open, which typically activates the screen. Clamshell phones were particularly popular before the advent of smartphones, as they offered a robust form factor and ease of use. The design also often incorporated features like a secondary external display, which could show incoming calls or notifications without needing to open the phone. While they have largely been replaced by touchscreen smartphones, they have seen a resurgence in recent years for their simplicity and practicality.
