Smartphone

The term Smartphone has been in wide usage since the start of the 21st century, but has essentially come to mean a mobile phone (that is, capable of making and receiving calls via a cell network), with a touch screen, that runs one of the following operating systems:


 * Android
 * iOS
 * Windows Phone / Windows Mobile

The Windows Phone and Windows Mobile operating systems have been defunct since Nokia sold their mobile phone business leaving the market dominated by iOS and Android. iOS devices are manufactured by Apple, Inc., while the Android market is split, primarily between Acer, ARCHOS, ASUS, Google, HTC, Huawei, Kyocera, LG, Motorola, Panasonic, Samsung, Sony and ZTE.
