Mobile operating systems

A mobile operating system is an operating system for mobile phones, tablets, smartwatches, smartglasses, or other non-laptop personal mobile computing devices. While computers such as typical laptops are "mobile", the operating systems used on them are generally not considered mobile ones, as they were originally designed for desktop computers that historically did not have or need specific ''mobile'' features. This 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 hardware of the past. Key notabilities blurring this line are the introduction of tablet computers and light-weight laptops and the hybridization of the two in 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 telephony and data connection. In Q1 2018, over 383 million smartphones were sold (highest ever recorded) with 86.2 percent running Android and 12.9 percent running iOS. Nonetheless, although not as many as 2018 (1.56 billion), 2021 still had soaring sales, 1.43 billion to be exact with 83.32 percent being Android. Android alone is more popular than the popular desktop operating system Microsoft Windows, and in general smartphone use (even without tablets) outnumbers desktop use.

Mobile devices, with mobile communications abilities (e.g., smartphones), contain two mobile operating systemsthe 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) having majority use, more used than any other kind of device.TechFoogle, June 30, 2019
Top 10 Mobile Operating System
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 countries such as United States and United Kingdom.

Current software platforms

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

Android

Android (based on the modified Linux kernel) is a mobile operating system developed by Google. The base system is open-source (and only the kernel copyleft), but the apps and drivers which provide functionality are increasingly becoming closed-source. 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, in devices sold, much of the software bundled with it (including Google apps and vendor-installed software) is proprietary software and closed-source.

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. The current Android version is Android 13, released on August 15, 2022.

Android One

Android One, a successor to Google Nexus, is a software experience that runs on the unmodified Android operating system. Unlike most of the "stock" Androids running on the market, the Android One User Interface (UI) closely resembles the Google Pixel UI, due to Android One being a software experience developed by Google and distributed to partners such as Nokia Mobile (HMD) and Xiaomi. Thus, the UI is intended to be as clean as possible. Original equipment manufacturer (OEM) partners may tweak or add additional apps such as cameras to the firmware, but most of the apps are handled proprietarily by Google. Operating system updates are handled by Google and internally tested by OEMs before being distributed via an OTA update to end users.

LineageOS

Lineage Android Distribution is a custom mobile operating system based on the Android Open Source Project (AOSP). It serves as the successor to the highly popular custom ROM, CyanogenMod, from which it was forked in December 2016 when Cyanogen Inc. announced it was discontinuing development and shut down the infrastructure behind the project. Since Cyanogen Inc. retained the rights to the Cyanogen name, the project rebranded its fork as LineageOS.

Similar to CyanogenMod, it does not include any proprietary apps unless the user installs them. It allows Android users who can no longer obtain update support from their manufacturer to continue updating their OS version to the latest one based on official release from Google AOSP and heavy theme customization.

Magic UI

Magic UI is a front-end touch interface developed by Honor as a subsidiary of Huawei Technologies Co. Ltd before Honor became an independent company.

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.

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

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.

Each Sailfish OS version release is named after a Finnish lake:

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. On May 17, 2013, Tizen released version 2.1, code-named Nectarine.

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.

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.

It is a mix of closed-source and open-source components. 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). KaiOS is not entirely proprietary, as it uses the copyleft GPL Linux kernel also used in Android.

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 mainly on the atheistic such as the icon and some UI element, including custom Nokia ringtone and notification tone.

Fuchsia

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 licenses, permissive BSD licenses#3-clause, 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.

Currently LiteOS are introduce to the consumer market with the Huawei Watch GT series and their sub-brand Honor Magic Watch series.

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. 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.

It is closed-source and proprietary, and is built on the open source Darwin (operating system), 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, "iOS jailbreaking, 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.

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.

Windows Mobile is 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.

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.

Market share

Usage

In 2006, Android and iOS did not exist and only 64 million smartphones were sold. In 2018 Q1, 383.5 million smartphones were sold and global market share was 85.9% for Android and 14.1% for iOS. Other OS smartphones were 0,131 million, counting the 0.03% of the total.

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). 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), 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%. 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 amongst world leaders in use of mobile to surf the internet" (of the big countries) where the share is around (or over) 80% 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 wasn't a Christmas-time fluke, as while close to majority after smartphone majority happened again in March 2017.

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). 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). However, in some territories of the United States, such as Puerto Rico, desktop is way under majority, with Windows under 30% overtaken by Android.

On October 22, 2016 (and subsequent weekends), mobile showed majority. Since October 27, the desktop hasn't shown majority, not even on weekdays. And smartphones alone have showed majority since December 23 to the end of the year, with the share topping at 58.22% on Christmas Day. 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%.

, the world has turned desktop-minority; at about 49% desktop use for the previous month, but mobile wasn't 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).
