A smartphone, or smart phone, is a mobile phone built on a mobile operating system, with more advanced computing capability and connectivity than a feature phone. The first smartphones combined the functions of a personal digital assistant (PDA) with a mobile phone. Later models added the functionality of portable media players, low-end compact digital cameras,
pocket video cameras, and GPS navigation units to form one multi-use device. Many modern smartphones also include high-resolution touchscreens and web browsers that display standard web pages as well as mobile-optimized sites. High-speed data access is provided by Wi-Fi and mobile broadband. In recent years, the rapid development of mobile app markets and of mobile commerce have been drivers of smartphone adoption.
The mobile operating systems (OS) used by modern smartphones include Google’s Android, Apple’s iOS, Nokia’s Symbian, Blackberry Ltd’s BlackBerry OS, Samsung’s Bada, Microsoft’s Windows Phone, Hewlett-Packard’s webOS, and embedded Linux distributions such as Maemo and MeeGo. Such operating systems can be installed on many different phone models, and typically each device can receive multiple OS software updates over its lifetime. A few other upcoming operating systems are Mozilla’s Firefox OS, Canonical Ltd.’s Ubuntu Phone, and Tizen. Worldwide sales of smartphones exceeded those of feature phones in early 2013. As of July 18, 2013, 90 percent of global handset sales are attributed to the purchase of Android and iPhone smartphones.
