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.
Smartphones, which are usually pocket-sized, typically combine the features of a cell phone, such as the ability to receive and make phone calls and text messages, with those of other popular digital mobile devices. Other features typically include a personal digital assistant 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 a vareity of third-party software components.
They typically have a color graphical user interface screen that covers 70% or more of the front surface, with an LCD, OLED, AMOLED, LED, or similar screen; the screen is often a touchscreen.
In 1999, the Japanese firm NTT DoCoMo released the first smartphones to achieve mass adoption within a country.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.
Smart phones and social media expand our universe. We can connect with others or collect information easier and faster than ever.

Devices that combined telephony and computing were first conceptualized by Nikola Tesla in 1909 and Theodore Paraskevakos in 1971 and patented in 1974, and were offered for sale beginning in 1993. Paraskevakos was the first to introduce the concepts of intelligence, data processing and visual display screens into telephones.
In 1971, while he was working with Boeing in Huntsville, Alabama, Paraskevakos demonstrated a transmitter and receiver that provided additional ways to communicate with remote equipment, however it did not yet have general purpose PDA applications in a wireless device typical of smartphones. They were installed at Peoples’ Telephone Company in Leesburg, Alabama and were demonstrated to several telephone companies. The original and historic working models are still in the possession of Paraskevakos.
