A Smartphone is a mobile phone built on a mobile computing platform, with more advanced computing ability and connectivity than a feature phone. The initial Smartphone were devices which mainly combined the functions of a Personal Digital Assistant (PDA) and a mobile phone or a camera phone. Today's models also serve to combine the functions of portable media players, low-end compact digital cameras, pocket video cameras, and Global Positioning System (GPS) navigation units. Modern Smartphone typically also include high-resolution touch screens, web browsers that can access and properly display standard web pages rather than just mobile-optimized web sites, and high-speed data access via Wi-Fi and mobile broadband.
