Besides having the largest installed base worldwide on smartphones, it is also the most popular operating system for general purpose computersfurther 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, in devices sold, much of the software bundled with it (including Google apps and vendor-installed software) is proprietary software and closed source.

Chrome OSedit

Chrome OS 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, Chrome OS 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 Chrome OS 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 Chrome OS devices. With the support of Android applications, there are Chromebook devices that are positioned as tablet based instead of notebooks.

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

Sailfish OSedit

This article or section may need to be formatted. You can help Wikipedia by formatting it if you know how. Please also consider changing this notice to be more specific. (March 2020)

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 different 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:

Tizenedit

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 focus 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 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.

Current Tizen version list:

Tizen – 1.0 (Larkspur)
Tizen – 2.0 (Magnolia)
Tizen – 2.1 (Nectarine)
Tizen – 2.2.x
Tizen – 2.3.x
Tizen – 2.4.x (minor UI tweaks)
Tizen – RT 1.0
Tizen – 3.0 (minor UI tweaks)
Tizen – 4.0 (minor UI tweaks)
Tizen – 5.0 (under development)

KaiOSedit

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.

Fully open-source, entirely permissive licensesedit

Fuchsiaedit

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 Chrome OS 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 underwhich 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.

LiteOSedit

LiteOS is a 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 is released under the permissive BSD 3-clause license. Huawei LiteOS features lightweight, low-power, fast-response, multi-sensor collaboration, multi-protocol interconnect connectivity, enabling IoT terminals to quickly access the networkcitation needed. Huawei LiteOS will make intelligent hardware development easier. Thereby accelerating the realization of the interconnection of all things.peacock term Currently LiteOS are introduce to the consumer market with the Huawei Watch GT series and their sub-brand Honor Magic Watch series.

Current LiteOS version list:

LiteOS V2.1 – released in May 2018

Fully open-source, mixed copyleft and permissive licensesedit

PureOSedit

PureOS is a Debian GNU/Linux derivative using only free software meeting the Debian Free Software Guidelines, mainly the copyleft GPL. PureOS is endorsed by Free Software Foundation as one of the freedom-respecting operating systems. It is developed by Purism, and was already in use on Purism's laptops before it was used on the Librem 5 smartphone. Purism, in partnership with GNOME and KDE, aims to separate the CPU from the baseband processor and include hardware kill switches for the phone's Wi-Fi, Bluetooth, camera, microphone and baseband processor, and provide both GNOME and KDE Plasma Mobile as options for the desktop environment.

Ubuntu Touchedit

Ubuntu Touch is from Canonical Ltd.. It is open source and uses the GPL license. Ubuntu Touch as an OS is built using 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. As of August 2018update, the desktop environment of Ubuntu Touch is planned to be available as one of the default desktop options on the Librem 5 running PureOS as the operating system.

Though Canonical formally announced it was discontinuing the Ubuntu mobile OS with its integral component Unity8, the independent German non-profit UBPorts Community/("Foundation" paperwork pending in the local Berlin-government) decided to take over the project. Canonical started Ubuntu Touch based on Ubuntu 15.04 (Vivid Vervet) and UBPorts upgraded the base to the nearest, current long-term support version Ubuntu 16.04 LTS (Xenial Xerus).

Plasma mobileedit

Plasma Mobile is a Plasma variant for smartphones. Plasma Mobile runs on Wayland and it is compatible with Ubuntu Touch applications, PureOS applications, and eventually Android applications via KDE's Shashlik project – also sponsored by Blue Systems, or Anbox. It is under the copyleft GPLv2 license.

The Necuno phone uses Plasma Mobile. It is which is entirely open-source and thus does not have a cellular modem, so it must make calls by VOIP, like a pocket computer.

PostmarketOSedit

PostmarketOS is based on the Alpine Linux Linux distribution. It is intended to run on older phone hardware. As of 2019update it is in alpha.

LuneOSedit

LuneOS is a modern reimplementation of the Palm/HP webOS interface.

Closed sourceedit

iOSedit

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. It is closed source and proprietary, and is built on the open source Darwin operating system. The iPhone, iPod Touch, iPad and second or 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.

watchOSedit

watchOS is the operating system of the Apple Watch, developed by Apple Inc. It is based on the iOS operating system and has many similar features. It was released on April 24, 2015, along with the Apple Watch, the only device that runs watchOS. It is currently the most widely used wearable operating system. Its features focus on convenience, such as being able to place phone calls and send texts, and health, such as fitness and heart rate tracking.

The most current version of the watchOS operating system is watchOS 7.

Kindle firmwareedit

Kindle firmware is mobile operating system specifically design for Amazon Amazon Kindle e-readers, it is based on custom Linux kernel however it is entirely closed source and proprietary, and only runs on Amazon Kindle line up manufactured under Amazon brand.

Windows 10edit

Windows 10 (not to be confused with Windows 10 Mobile—see below) is a personal computer operating system developed and released by Microsoft as part of the Windows NT family of operating systems. It was released on July 29, 2015 and many editions and versions have been released since then. Just like its predecessors, it was designed to run across multiple Microsoft product such as PCs and Tablets. The Windows user interface was revised to handle transitions between a mouse-oriented interface and a touchscreen-optimized interface based on available input devices‍—‌particularly on 2-in-1 PCs.

Windows 10 also introduces the universal apps, expanding on Metro-style apps, these apps can be designed to run across multiple Microsoft product families with nearly identical code‍—‌including PCs, tablets, smartphones, embedded systems, Xbox One, Surface Hub and Mixed Reality.

Minor proprietary operating systemedit

Other than the major mobile operating system from the major tech company, some company such as Huami(Amazfit), Huawei, realme, TCL and Xiaomi has their own proprietary RTOS that develop specifically for their own smartband and smartwatch that is design to be power efficient and low battery consumption that is neither based on Android nor Linux Kernel.

Proprietary Amazfit OS

Operating System that is primarily design for their Bip series, however Huami is currently developing the operating system to run on other company smartwatch as well. (Not to be confused with the Android-based Amazfit OS as both of them sharing the name yet both are based on different operating system, for their Android based Amazfit OS, kindly refer to the Android section)

Huawei/Honor Band Operating System

BlackBerry 10edit

BlackBerry 10 (based on the QNX OS) is from BlackBerry. As a smartphone OS, it is closed source and proprietary, and only runs on phones and tablets manufactured by BlackBerry.

One of the dominant platforms in the world in late 2000s, its global market share was reduced significantly by mid-2010s. In late 2016, BlackBerry announced that it will continue to support the OS, with a promise to release 10.3.3. Therefore, BlackBerry 10 would not receive any major updates as BlackBerry and its partners would focus more on their Android base development.

Current BlackBerry 10 version list:

BlackBerry 10.0
BlackBerry 10.1
BlackBerry 10.2
BlackBerry 10.3 – major UI revamp
