A smartphone is a mobile phone with an advanced mobile operating system which combines features of a personal computer operating system with other features useful for mobile or handheld use.[1][2][3] Smartphones, which are usually pocket-sized, typically combine the features of a cell phone, such as the ability to receive and make phone calls, with those of other popular digital mobile devices. Other features typically include a personal digital assistant (PDA) for making appointments in a calendar, media player, video games, GPS navigation unit, digital camera and digital video camera. Most smartphones can access the Internet and can run third-party software components ("apps"). They typically have a color touchscreen graphical user interface that covers 70% or more of the front surface, with LCD, OLED, AMOLED, LED or similar screen.

In 1999, the Japanese firm NTT DoCoMo released the first smartphones[specify] to achieve mass adoption within a country.[citation needed] Smartphones became widespread in the 21st century and most of those produced from 2012 onwards have high-speed mobile broadband 4G LTE, motion sensors, and mobile payment features. In the third quarter of 2012, one billion smartphones were in use worldwide.[4] Global smartphone sales surpassed the sales figures for regular cell phones in early 2013.[5] As of 2013, 65 percent of U.S. mobile consumers own smartphones.[6] Android and iPhone owners account for half of the cell phone user population.
