Paleolithic, Mesolithic, Neolithic, Copper Age, Bronze Age, Iron Age and now the Tech Age! Welcome to my bright, bold and vivid photograph of a person using a Samsung smart phone.
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. It typically combines the features of a cell phone with those of other popular mobile devices, such as personal digital assistant (PDA), media player, GPS navigation unit and digital camera.
Most smartphones can access the Internet and can run third-party apps. They have a touchscreen user interface, with LCD, OLED, AMOLED, LED or similar screen. 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. – Wikipedia
