'''Category:Smartphone''' — 'smartphone' is the generic name (or {{Cambridge-Dictionary|noun}}) given to a evolution of {{tag|mobile phones}} with enhanced features. The Oxford Cambridge English Dictionary definition of [[Oxford{{Cambridge-dict:smartphoneDictionary|smartphone]] }} states "a mobile phone that can be used as a small computer and that connects to the internet". The Oxford English Dictionary definition states "(a) mobile phone that performs many of the functions of a computer, typically having a touchscreen interface, internet access, and an operating system capable of running downloaded apps". Typically, these multifunction devices operate on the {{tag|GSM}} (Global System for Mobile) mobile phone networks; usually with a minimum specification of 3G (third generation), though 4G (fourth generation) is required to exploit their full functionality. Their included 'always on' {{tag|internet}} connectivity allows support for a range of [[:Category:Applications|applications]] (commonly known merely as 'apps'); such as {{tag|video }} streaming, [[:Category:Map|mapping ]] with satellite navigation, [[:Category:Social networking|social media ]] sites such as {{tag|Facebook}} and {{tag|Twitter}}, high quality still- (more than 5MP) and video-cameras (often HD). A key feature of all smartphones is that they can be fully customised by downloading a massive selection of 'apps'; including specifically paired-down applications such as [[:Category:Wikipedia|Wikipedia]] and [[:Category:Wiktionary|Wiktionary]], [[:Category:YouTube|YouTube]], professional [[:Category:Weather|weather]] apps, and an unthinkably wide array of many other apps for [[:Category:Business|business]], [[:Category:Commerce|commerce]], [[:Category:Finance|finance]] ([[:Category:Banking|banking]], [[:Category:Money|money]] exchange, stocks and shares trading, etc), [[:Category:Sport|sports]], [[:Category:Travel|travel]], [[:Category:Recreation|recreation]], [[:Category:Hobbies|hobbies]], [[:Category:Health|health]], [[:Category:Education|education]], [[:Category:DIY|DIY]], [[:Category:Lifestyles|lifestyles ]] . . . oh, and [[:Category:Video games|video games]]. Smartphones generally fall into four umbrella classes, defined by their [[:Category:Operating system|operating system]] (OS). The majority market share is powered by {{tag|Android}} (from {{tag|Google}}), followed by the {{tag|iOS}} (from {{tag|Apple}}), then {{tag|Blackberry}} (from RiM), and finally the smallest market share by far which uses a hugely paired down version of [[:Category:Windows|Windows]] called {{tag|Windows Mobile}} (now defunct, from {{tag|Microsoft}}).
