For a list, see Comparison of mobile operating systems.

A mobile operating system is an operating system used for smartphones, tablets, smartwatches, smartglasses, or other non-laptop personal mobile computing devices. While computers such as laptops are "mobile", the operating systems used on them are usually not considered mobile, as they were originally designed for desktop computers that historically did not have or need specific mobile features. This "fine line" distinguishing mobile and other forms has become blurred in recent years, due to the fact that newer devices have become smaller and more mobile, unlike the hardware of the past. Key notabilities blurring this line are the introduction of tablet computers, light laptops, and the hybridization of the 2-in-1 PCs.

Mobile operating systems combine features of a desktop computer operating system with other features useful for mobile or handheld use, and usually including a wireless inbuilt modem and SIM tray for telephone and data connection. In Q1 2018, over 123 million smartphones were sold (the most ever recorded) with 60.2% running Android and 20.9% running iOS.[1] Sales in 2012 were 1.56 billion; sales in 2023 were 1.43 billion[2] with 53.32% being Android.[3] Android alone has more sales than the popular desktop operating system Microsoft Windows, and smartphone use (even without tablets) outnumbers desktop use.[4]

Mobile devices, with mobile communications abilities (for example, 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.[5]

Mobile operating systems have had the most use of any operating system since 2017 (measured by web use).[2]

These operating systems often run atop baseband or other real-time operating systems that handle hardware aspects of the phone.

Android

Main articles: Android (operating system), Android version history, and List of custom Android distributions

Android (based on the modified Linux kernel) is a mobile operating system developed by Open Handset Alliance.[118] The base system is open-source (and only the kernel copyleft), but the apps and drivers which provide functionality are increasingly becoming closed-source.[119] Besides having the largest installed base worldwide on smartphones, it is also the most popular operating system for general purpose computers[further explanation needed] (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,[120] in devices sold, much of the software bundled with it (including Google apps and vendor-installed software) is proprietary software and closed-source.[121]

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. Both phone and tablet compatibility were merged with Android 4.0.

Many OEMs ship their devices with custom skins and numerous forks of Android are available to use as custom ROMs.

Wear OS

Main article: Wear OS

Wear OS (also known simply as Wear and formerly Android Wear) is a version of Google's Android operating system designed for smartwatches and other wearables. By pairing with mobile phones running Android version 6.0 or newer, or iOS version 10.0 or newer with limited support from Google's pairing application, Wear OS integrates Google Assistant technology and mobile notifications into a smartwatch form factor.

In May 2021 at Google I/O, Google announced a major update to the platform, internally known as Wear OS 3.0. It incorporates a new visual design inspired by Android 12, and Fitbit exercise tracking features. Google also announced a partnership with Samsung Electronics, who is collaborating with Google to unify its Tizen-based smartwatch platform with Wear OS, and has committed to using Wear OS on its future smartwatch products starting with One UI Watch 3.0. The underlying codebase was also upgraded to Android 11.

ChromeOS

Main article: ChromeOS

ChromeOS is an operating system designed by Google that is based on the Linux kernel and uses the Google Chrome web browser as its principal user interface. As a result, ChromeOS primarily supports web applications. Google announced the project in July 2009, conceiving it as an operating system in which both applications and user data reside in the cloud: hence ChromeOS primarily runs web applications.[122]

Due to increase of popularity with 2-in-1 PCs, most recent Chromebooks are introduced with touch screen capability, with Android applications starting to become available for the operating system in 2014. And in 2016, access to Android apps in the entire Google Play Store was introduced on supported ChromeOS devices. With the support of Android applications, there are Chromebook devices that are positioned as tablet based instead of notebooks.

ChromeOS is only available pre-installed on hardware from Google manufacturing partners. An open source equivalent, ChromiumOS, can be compiled from downloaded source code. Early on, Google provided design goals for ChromeOS, but has not otherwise released a technical description.

Sailfish OS

Main article: Sailfish OS

Sailfish OS is from Jolla. It is open source with GNU General Public License (GPL) for middleware stack core which comes from MER. Sailfish due to Jolla's business model and due to alliances with various partners and due to intentional design of OS internals, is capable to adopt in several layers third-party software including Jolla software e.g. Jolla's UI is proprietary software (closed source), so such components can be proprietary with many kinds of licences. However, user can replace them with open source components like e.g. NEMO UI instead Jolla's UI.

After Nokia abandoned in 2011 the MeeGo project, most of the MeeGo team left Nokia, and established Jolla as a company to use MeeGo and Mer business opportunities. The MER standard allows it to be launched on any hardware with kernel compatible with MER. In 2012, Linux Sailfish OS based on MeeGo and using middleware of MER core stack distribution was launched for public use. The first device, the Jolla smartphone, was unveiled on May 20, 2013. In 2015, Jolla Tablet was launched and the BRICS countries declared it an officially supported OS there. Jolla started licensing Sailfish OS 2.0 for third parties. Some devices sold are updateable to Sailfish 2.0 with no limits.

Nemo Mobile is a community-driven OS, similar to Sailfish but attempting to replace its proprietary components, such as the user interface.[123][124][125]

SteamOS

Main article: SteamOS

SteamOS is a Linux distribution developed by Valve. It incorporates Valve's popular namesake Steam video game storefront and is the primary operating system for Steam Machines and the Steam Deck. SteamOS is open source with some closed source components.

SteamOS was originally built to support streaming of video games from one personal computer to the one running SteamOS within the same network, although the operating system can support standalone systems and was intended to be used as part of Valve's Steam Machine platform. SteamOS versions 1.0, released in December 2013, and 2.0 were based on the Debian distribution of Linux with GNOME desktop.[126] With SteamOS, Valve encouraged developers to incorporate Linux compatibility into their releases to better support Linux gaming options.

In February 2022, Valve released the handheld gaming computer Steam Deck running SteamOS 3.0. SteamOS 3 is based on the Arch Linux distribution with KDE Plasma 5.[127][128]

Tizen

Main article: Tizen

Tizen (based on the Linux kernel) is a mobile operating system hosted by Linux Foundation, together with support from the Tizen Association, guided by a Technical Steering Group composed of Intel and Samsung.

Tizen is an operating system for devices including smartphones, tablets, In-Vehicle Infotainment (IVI) devices, however currently it mainly focuses on wearable and smart TVs. It is an open source system (however the SDK was closed-source and proprietary) that aims to offer a consistent user experience across devices. Tizen's main components are the Linux kernel and the WebKit runtime. According to Intel, Tizen "combines the best of LiMo and MeeGo." HTML5 apps are emphasized, with MeeGo encouraging its members to transition to Tizen, stating that the "future belongs to HTML5-based applications, outside of a relatively small percentage of apps, and we are firmly convinced that our investment needs to shift toward HTML5." Tizen will be targeted at a variety of platforms such as handsets, touch pc, smart TVs and in-vehicle entertainment.[129][130] On May 17, 2013, Tizen released version 2.1, code-named Nectarine.[131]

While Tizen itself was open source, most of the UX and UI layer that was developed by Samsung was mainly closed-source and proprietary, such as the TouchWiz UI on the Samsung Z's series smartphone and One UI for their Galaxy Watch wearable lines.

Note that some refrigerators use Tizen,[132] even though they are not considered mobile devices.

KaiOS

Main article: KaiOS

KaiOS is from Kai. It is based on Firefox OS/Boot to Gecko. Unlike most mobile operating systems which focus on smartphones, KaiOS was developed mainly for feature phones, giving these access to more advanced technologies usually found on smartphones, such as app stores and Wi-Fi/4G capabilities.[133]

It is a mix of closed-source and open-source components.[134][135] FirefoxOS/B2G was released under the permissive MPL 2.0. It does not redistribute itself under the same license, so KaiOS is now presumably proprietary (but still mostly open-source, publishing its source code).[134][135] KaiOS is not entirely proprietary, as it uses the copyleft GPL Linux kernel also used in Android.[136]

Smart Feature OS

Smart Feature OS is a custom version of KaiOS that was developed and solely used by HMD Global for their KaiOS line of Nokia feature phone. The main differences between stock KaiOS and Smart Feature OS is the aesthetics such as icons, widgets, a custom Nokia ringtone and notification tone.

Fully open-source, entirely permissive licenses

Fuchsia

Main article: Fuchsia (operating system)

Fuchsia is a capability-based, real-time operating system (RTOS) currently being developed by Google. It was first discovered as a mysterious code post on GitHub in August 2016, without any official announcement. In contrast to prior Google-developed operating systems such as ChromeOS and Android, which are based on Linux kernels, Fuchsia is based on a new microkernel called "Zircon", derived from "Little Kernel", a small operating system intended for embedded systems. This allows it to remove Linux and the copyleft GPL under which the Linux kernel is licensed; Fuchsia is licensed under the permissive BSD 3-clause, Apache 2.0, and MIT licenses. Upon inspection, media outlets noted that the code post on GitHub suggested Fuchsia's capability to run on universal devices, from embedded systems to smartphones, tablets and personal computers. In May 2017, Fuchsia was updated with a user interface, along with a developer writing that the project was not a for experimental, prompting media speculation about Google's intentions with the operating system, including the possibility of it replacing Android.[137]

LiteOS

Main article: LiteOS

LiteOS is a discontinued lightweight open source real-time operating system which is part of Huawei's "1+2+1" Internet of Things solution, which is similar to Google Android Things and Samsung Tizen. It was released under the permissive BSD 3-clause license. LiteOS was used in the Huawei Watch GT series and their sub-brand Honor Magic Watch series.[citation needed]

OpenHarmony

Main article: OpenHarmony

OpenHarmony is an open-source version of HarmonyOS developed and donated by Huawei to the OpenAtom Foundation. It supports devices running a mini system with memory as small as 128 KB, or running a standard system with memory greater than 128 MB. The open source HarmonyOS is based on the Huawei LiteOS kernel and Linux kernel for standard systems. OpenHarmony LiteOS Cortex-A brings small-sized, low-power, and high-performance experience and builds a unified and open ecosystem for developers. In addition, it provides rich kernel mechanisms, more comprehensive Portable Operating System Interface (POSIX), and a unified driver framework, Hardware Driver Foundation (HDF), which offers unified access for device developers and friendly development experience for application developers.[citation needed]

Thumb
Ubuntu Touch

Ubuntu Touch is an open-source (GPL) mobile version of the Ubuntu operating system[112] originally developed in 2013 by Canonical Ltd. and continued by the non-profit UBports Foundation in 2017.[148][149] Ubuntu Touch can run on a pure GNU/Linux base on phones with the required drivers, such as the Librem 5[140] and the PinePhone.[150] To enable hardware that was originally shipped with Android, Ubuntu Touch makes use of the Android Linux kernel, using Android drivers and services via an LXC container, but does not use any of the Java-like code of Android.[151][152] As of February 2022, Ubuntu Touch is available on 78 phones and tablets.[112][153] The UBports Installer serves as an easy-to-use tool to allow inexperienced users to install the operating system on third-party devices without damaging their hardware.[112][154]

Closed source

iOS

Main articles: iOS and iOS version history

iOS (formerly named iPhone OS) was created by Apple Inc. It has the second largest installed base worldwide on smartphones, but the largest profits, due to aggressive price competition between Android-based manufacturers.[155] It is closed-source and proprietary, and is built on the open source Darwin operating system. The iPhone, iPod Touch, iPad, and second and third-generation Apple TV all use iOS, which is derived from macOS.

Native third-party applications were not officially supported until the release of iPhone OS 2.0 on July 11, 2008. Before this, "jailbreaking" allowed third-party applications to be installed. In recent years, the jailbreaking scene has changed drastically due to Apple's continued efforts to secure their operating system and prevent unauthorized modifications. Currently, jailbreaks of recent iterations of iOS are only semi-untethered, which requires a device to be re-jailbroken at every boot, and exploits for jailbreaks are becoming increasingly hard to find and use.

Currently all iOS devices are developed by Apple and manufactured by Foxconn or another of Apple's partners.

iPadOS

Main article: iPadOS

iPadOS is a tablet operating system created and developed by Apple Inc. specifically for their iPad line of tablet computers. It was announced at the company's 2019 Worldwide Developers Conference (WWDC), as a derivation from iOS but with a greater emphasis put on multitasking. It was released on September 24, 2019.

CyanogenMod was a custom mobile operating system based on the Android Open Source Project (AOSP). It was a custom ROM that was co-developed by the CyanogenMod community. The OS did not include any proprietary apps unless the user installed them. Due to its open source nature, CyanogenMod allowed Android users who could no longer obtain update support from their manufacturer to continue updating their OS version to the latest one based on official releases from Google AOSP and heavy theme customization. The last version of the OS was CyanogenMod 13 which was based on Android Asus.

On December 24, 2016, CyanogenMod announced on their blog that they would no longer be releasing any CyanogenMod updates. All development moved to LineageOS.

See also: Comparison of Firefox OS devices

Firefox OS (formerly known as "Boot to Gecko" and shortly "B2G")[156] is from Mozilla. It was an open source mobile operating system released under the Mozilla Public License built on the Android Linux kernel and used Android drivers, but did not use any Java-like code of Android.

According to Ars Technica, "Mozilla says that B2G is motivated by a desire to demonstrate that the standards-based open Web has the potential to be a competitive alternative to the existing single-vendor application development stacks offered by the dominant mobile operating systems."[157] In September 2016, Mozilla announced that work on Firefox OS has ceased, and all B2G-related code would be removed from mozilla-central.[158]

MeeGo/Maemo/Moblin

Main articles: MeeGo, Maemo, and Moblin

MeeGo was from non-profit organization The Linux Foundation. It is open source and GPL. At the 2010 Mobile World Congress in Barcelona, Nokia and Intel both unveiled MeeGo, a mobile operating system that combined Moblin and Maemo to create an open-sourced experience for users across all devices. In 2011 Nokia announced that it would no longer pursue MeeGo in favor of Windows Phone. Nokia announced the Nokia N9 on June 21, 2011, at the Nokia Connection event[159] in Singapore. LG announced its support for the platform.[160] Maemo was a platform developed by Nokia for smartphones and Internet tablets. It is open source and GPL, based on Debian GNU/Linux and draws much of its graphical user interface (GUI), frameworks, and libraries from the GNOME project. It uses the Matchbox window manager and the GTK-based Hildon as its GUI and application framework.

Bada

Main article: Bada (operating system)

Bada platform (stylized as bada; Korean: 바다) was an operating system for mobile devices such as smartphones and tablet computers. It was developed by Samsung Electronics. Its name is derived from "바다 (bada)", meaning "ocean" or "sea" in Korean. It ranges from mid- to high-end smartphones. To foster adoption of Bada OS, since 2011 Samsung reportedly has considered releasing the source code under an open-source license, and expanding device support to include Smart TVs. Samsung announced in June 2012 intentions to merge Bada into the Tizen project, but would meanwhile use its own Bada operating system, in parallel with Google Android OS and Microsoft Windows Phone, for its smartphones. All Bada-powered devices are branded under the Wave name, but not all of Samsung's Android-powered devices are branded under the name Galaxy. On February 25, 2013, Samsung announced that it will stop developing Bada, moving development to Tizen instead. Bug reporting was finally terminated in April 2014.[164]

Windows Mobile was a family of proprietary operating systems from Microsoft aimed at business and enterprise users, based on Windows CE and originally developed for Pocket PC (PDA) devices. In 2010 it was replaced with the consumer-focused Windows Phone.[118][55]

Versions of Windows Mobile came in multiple editions, like "Pocket PC Premium", "Pocket PC Professional", "Pocket PC Phone", and "Smartphone" (Windows Mobile 2003) or "Professional", "Standard", and "Classic" (Windows Mobile 6.0). Some editions were touchscreen-only and some were keyboard-only, although there were cases where device vendors managed to graft support for one onto an edition targeted at the other. Cellular phone features were also only supported by some editions. Microsoft started work on a version of Windows Mobile that would combine all features together, but it was aborted, and instead they focused on developing the non-backward-compatible, touchscreen-only Windows Phone 7.[76]

Windows Phone
Main articles: Windows Phone and Windows 10 Mobile

Windows Phone is a proprietary mobile operating system developed by Microsoft for smartphones as the replacement successor to Windows Mobile and Zune. Windows Phone features a new touchscreen-oriented user interface derived from Metro design language.

Unveiled on February 15, 2010, Windows Phone included a user interface inspired by Microsoft's Metro Design Language. It was integrated with Microsoft services such as OneDrive and Office, Xbox Music, Xbox Video, Xbox Live games, and Bing, but also integrated with many other non-Microsoft services such as Facebook and Google accounts. Windows Phone devices were made primarily by Microsoft Mobile/Nokia, and also by HTC and Samsung.

On January 21, 2015, Microsoft announced that the Windows Phone brand would be phased out and replaced with Windows 10 Mobile, bringing tighter integration and unification with its PC counterpart Windows 10, and providing a platform for smartphones and tablets with screen sizes under 8 inches.

On October 8, 2017, Microsoft officially announced that they would no longer push any major updates to Windows 10 Mobile. The operating system was put in maintenance mode, where Microsoft would push bug fixes and general improvements only. Windows 10 Mobile would not receive any new feature updates.[113][114]

On January 18, 2019, Microsoft announced that support for Windows 10 Mobile would end on December 10, 2019, with no further security updates released after then, and that Windows 10 Mobile users should migrate to iOS or Android phones.[116][117]

In 2006, Android and iOS did not exist and only 64 million smartphones were sold.[171] In 2018 Q1, 183.5 million smartphones were sold and global market share was 48.9% for Android and 19.1% for iOS. Only 131,000 smartphones running other operating systems were sold, constituting 0.03% of sales.[172]

According to StatCounter web use statistics (a proxy for all use), smartphones (alone without tablets) have majority use globally, with desktop computers used much less (and Android, in particular, more popular than Windows).[173] Use varies however by continent with smartphones way more popular in the biggest continents, i.e. Asia, and the desktop still more popular in some, though not in North America.

The desktop is still popular in many countries (while overall down to 44.9% in the first quarter of 2017[174]), smartphones are more popular even in many developed countries (or about to be in more). A few countries on any continent are desktop-minority; European countries (and some in South America, and a few, e.g. Haiti, in North America; and most in Asia and Africa) are smartphone-majority, Poland and Turkey highest with 57.68% and 62.33%, respectively. In Ireland, smartphone use at 45.55% outnumbers desktop use and mobile as a whole gains majority when including the tablet share at 9.12%.[175][174] Spain is also slightly desktop-minority.

The range of measured mobile web use varies a lot by country, and a StatCounter press release recognizes "India among world leaders in use of mobile to surf the internet"[176] (of the big countries) where the share is around (or over) 80%[177] and desktop is at 19.56%, with Russia trailing with 17.8% mobile use (and desktop the rest).

Smartphones (alone, without tablets), first gained majority in December 2016 (desktop-majority was lost the month before), and it was not a Christmas-time fluke, as while close to majority after smartphone majority happened again in March 2017.[174]

In the week from November 7–13, 2016, smartphones alone (without tablets) overtook desktop, for the first time (for a short period; non-full-month).[178] Mobile-majority applies to countries such as Paraguay in South America, Poland in Europe and Turkey; and most of Asia and Africa. Some of the world is still desktop-majority, with e.g. in the United States at 54.89% (but no not on all days).[179] However, in some territories of the United States, such as Puerto Rico,[180] desktop is way under majority, with Windows under 30% overtaken by Android.

On October 22, 2016 (and subsequent weekends), mobile showed majority.[181] Since October 27, the desktop has not shown majority, not even on weekdays. Smartphones alone have shown majority since December 23 to the end of the year, with the share topping at 58.22% on Christmas Day.[182] To the "mobile"-majority share then of smartphones, tablets could be added giving a 63.22% majority. While an unusually high top, a similarly high also happened on Monday April 17, 2017, with then only smartphones share slightly lower and tablet share slightly higher, with them combined at 62.88%.

According to a StatCounter November 1, 2016 press release, the world has turned desktop-minority;[183] at about 49% desktop use for the previous month, but mobile was not ranked higher, tablet share had to be added to it to exceed desktop share. By now, mobile (smartphones) have full majority, outnumbering desktop/laptop computers by a safe margin (and no longer counting tablets with desktops makes them most popular).
