A mobile OS typically starts up when a device powers on, presenting a screen with icons or tiles that present information and provide application access. Mobile operating systems also manage cellular and wireless network connectivity, as well as phone access. Examples of mobile device operating systems include Apple iOS, Google Android, Research in Motionâs BlackBerry OS, Nokiaâs Symbian, Hewlett-Packardâs webOS (formerly Palm OS) and Microsoftâs Windows Phone OS. Some, such as Microsoftâs Windows 8, function as both a traditional desktop OS and a mobile operating system.
