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 Motion’s BlackBerry OS, Nokia’s Symbian, Hewlett-Packard’s webOS (formerly Palm OS) and Microsoft’s Windows Phone OS. Some, such as Microsoft’s Windows 8, function as both a traditional desktop OS and a mobile operating system.
Most mobile operating systems are tied to specific hardware, with little flexibility. Users can jailbreak or root some devices, however, which allows them to install another mobile OS or unlock restricted applications.
Mobile operating system
A mobile operating system (or mobile OS) is an operating system for phones, tablets, smartwatches, or other mobile devices. While computers such as typical laptops are 'mobile', the operating systems usually used on them are not considered mobile ones, as they were originally designed for desktop computers that historically did not have or need specific mobile features. This distinction is becoming blurred in some newer operating systems that are hybrids made for both uses.
Mobile operating systems combine features of a personal computer operating system with other features useful for mobile or handheld use; usually including, and most of the following considered essential in modern mobile systems; a touchscreen, cellular, Bluetooth, Wi-Fi Protected Access, Wi-Fi, Global Positioning System (GPS) mobile navigation, video- and single-frame picture cameras, speech recognition, voice recorder, music player, near field communication, and infrared blaster. By Q1 2018, over 383 million smartphones were sold with 85.9 percent running Android, 14.1 percent running iOS and other OSes negligible.[1] Android alone is more popular than the popular desktop operating system Windows, and in general smartphone use (even without tablets) outnumber desktop use.

Mobile devices with mobile communications abilities (e.g., smartphones) contain two mobile operating systems – the main user-facing software platform is supplemented by a second low-level proprietary real-time operating system which operates the radio and other hardware. Research has shown that these low-level systems may contain a range of security vulnerabilities permitting malicious base stations to gain high levels of control over the mobile device.
Mobile operating systems have majority use since 2017 (measured by web use); with even only the smartphones running them (excluding tablets) more used than any other kind of device.[3] Thus traditional desktop OS is now a minority used kind of OS; see usage share of operating systems. However, variations occur in popularity by regions, while desktop-minority also applies on some days in regions such as United States and United Kingdom.
Current software platforms
Android (based on the modified Linux kernel) is a mobile operating system developed by Google Inc.[8] Besides having the largest installed base worldwide on smartphones, it is also the most popular operating system for general purpose computers (a category that includes desktop computers and mobile devices), even though Android is not a popular operating system for regular (desktop) personal computers (PCs). Although the Android operating system is free and open-source software,[9] in devices sold, much of the software bundled with it (including Google apps and vendor-installed software) is proprietary software and closed source.[10]
Android's releases before 2.0 (1.0, 1.5, 1.6) were used exclusively on mobile phones. Android 2.x releases were mostly used for mobile phones but also some tablets, Android 3.0 was a tablet-oriented release and does not officially run on mobile phones, while both phone and tablet compatibility was merged with Android 4.0. The current Android version is 8.0 Oreo.
