Foldable phones are innovative devices that feature flexible screens, allowing them to be opened and closed like a book. This design enables users to enjoy a larger display while maintaining a compact size for portability. When unfolded, the screen can provide a tablet-like experience, making it easier to multitask and view content. These phones typically use advanced materials, such as flexible OLED displays, to achieve their unique form factor. Major tech companies, including Samsung and Huawei, have introduced foldable models, showcasing the potential for new ways to interact with mobile technology.
