Flip phones are mobile devices that feature a hinged design, allowing them to fold in half. This compact form makes them easy to carry and protects the screen when closed. They typically have a physical keypad and a small display, focusing on basic functions like calling and texting rather than advanced features. While flip phones were once the standard for mobile communication, their popularity declined with the rise of smartphones. However, they have seen a resurgence among users who prefer simplicity, longer battery life, and reduced distractions. Some modern flip phones even include smart features, bridging the gap between traditional and contemporary technology.
