Share of worldwide 2011 Q2 smartphone sales to end users by operating system, according to Gartner.[1]

A mobile operating system, also known as a mobile OS, a mobile platform, or a handheld operating system, is the operating system that controls a mobile device or information appliance—similar in principle to an operating system such as Windows, Mac OS X, or Linux that controls a desktop computer or laptop. However, they are currently somewhat simpler, and deal more with the wireless versions of broadband and local connectivity, mobile multimedia formats, and different input methods.

Typical examples of devices running a mobile operating system are smartphones, personal digital assistants (PDAs), tablet computers and information appliances, or what are sometimes referred to as smart devices, which may also include embedded systems, or other mobile devices and wireless devices.

History

The increasing importance of mobile devices has triggered intense competition amongst software giants such as Google, Microsoft, and Apple, as well as mobile industry leaders Nokia, Research In Motion (RIM), and Palm, in a bid to capture the largest market share pre-emptively.[2]

With the release of the iPhone in 2007, Apple significantly disrupted the mobile industry and effectively ushered in a new era of smartphone operating systems that focus on user experience and rely on touch-based interaction. In November 2007,Google formed the Open Handset Alliance with 79 other hardware, software, and telecom companies to make inroads into the smartphone market through its new Android operating system.[3] Though its reception was mainly positive from the media and public, the release of Android created a rift between Apple and Google, eventually leading to the resignation of Google's CEO, Eric Schmidt, from Apple's board of directors.[4]

Since the launch of both Apple's iOS and Google's Android, the smartphone market has exploded in popularity and in May 2010, accounted for more than 17.3% of all mobile phones sold.[5] This has led to greater consumer awareness of the various mobile operating systems, with telecoms and manufacturers regularly advertising the advantages of their OS. As of January 2011, Google holds 33.3% of the smartphone market worldwide, demonstrating amazing growth for Android which held only 4.7% a year earlier. Nokia, Apple, RIM, and Microsoft hold 31%, 16.2%, 14.6%, and 3.1% respectively.[6]

Market projection

Mobile platforms are in the nascent stage and any projection regarding market growth is hard to make at the present time. However, a clear trend is the surging growth of mobile operating systems which are developed for smart devices, rather than for feature phones. As of February 2011, Nokia has announced a partnership with Microsoft which effectively ends the development of Symbian OS, the most popular feature phone OS, by the end of 2011 in favor of Windows Phone.

It is noteworthy that Intel is taking the initiative to focus on portable devices other than mobile phones. They are Mobile Internet Devices (MID) and Ultra-Mobile PC (UMPC). Meantime, Palm abandoned its plan to develop Foleo, which was to be a companion device for a smartphone.

Mobile navigation

Canalys has estimated that in 2009 the installed base of smartphones with integrated GPS was 163 million units worldwide, of which Nokia accounted for more than half (51%), having shipped cumulatively 83 million GPS devices. On January 22, 2010, Nokia released a free version of Ovi Maps in an effort to increase its number of users.

Smartphone operating systems

Operating systems that can be found on smartphones include Google's Android, Apple's iOS, RIM's BlackBerry OS, Microsoft's Windows Phone, Linux, HP's webOS, Samsung's Bada, Nokia's MeeGo among many others. Android, Bada, webOS and Maemo are built on top of Linux, and iOS is derived from the BSD and NeXTSTEP operating systems, which are all related to Unix.

Common platforms

The most common operating systems (OS) used in smartphones are:

Android from Google Inc. [7] (open source, Apache)
Android was developed by a small startup company that was purchased by Google Inc., and Google continues to update the software. Android is an open source, Linux-derived platform backed by Google, along with major hardware and software developers (such as Intel, HTC, ARM, Samsung, Motorola and eBay, to name a few), that form the Open Handset Alliance.[8] Released on November 5th 2007, the OS has a following among programmers.[9] There have been seven releases of Android- Android 1.0, 1.5, 1.6, 2.0, 2.1, 2.2 and 2.3. All are nicknamed after a dessert item like Cupcake (1.5) or Frozen Yogurt (2.2). Most major mobile service providers carry an Android device. Since the HTC Dream (T-Mobile G1) was introduced, there has been an explosion in the number of devices that carry Android OS. From Q2 of 2009 to the second quarter of 2010, Android's worldwide market share rose 850% from 1.8% to 17.2%.
BlackBerry OS from RIM (closed source, proprietary)
This OS is focused on easy operation and was originally designed for business. Recently it has seen a surge in third-party applications and has been improved to offer full multimedia support. Currently Blackberry's App World has over 15,000 downloadable applications. RIM's future strategy will focus on the newly acquired QNX, having already launched the BlackBerry PlayBook tablet running a version of QNX and expecting the first QNX smartphones in early 2012. [10]
File:Palm-pre-webos-lg.png
The Palm Pre running HP (formerly Palm) webOS. HP purchased Palm in 2010.
iOS from Apple Inc. [7] (closed source, proprietary)
The Apple iPhone, iPod Touch and iPad all use an operating system called iOS, which is derived from Mac OS X. Third party applications were not officially supported until the release of iOS 2.0 on July 11th 2008. Before this, "jailbreaking" allowed third party applications to be installed, and this method is still available. Currently all iOS devices are developed by Apple and manufactured by Foxconn or another of Apple's partners.
Symbian OS from the Symbian Foundation [7] (open public license)
Symbian has the largest share in most markets worldwide, but lags behind other companies in the relatively small but highly visible North American market.[11] This matches the success of Nokia in all markets except Japan. In Japan Symbian is strong due to a relationship with NTT DoCoMo, with only one of the 44 Symbian handsets released in Japan coming from Nokia.[12] It has been used by many major handset manufacturers, including BenQ, Fujitsu, LG, Mitsubishi, Motorola, Nokia, Samsung, Sharp, and Sony Ericsson. Current Symbian-based devices are being made by Fujitsu, Nokia, Samsung, Sharp, and Sony Ericsson. Prior to 2009 Symbian supported multiple user interfaces, i.e. UIQ from UIQ Technologies, S60 from Nokia, and MOAP from NTT DOCOMO. As part of the formation of the Symbian platform in 2009 these three UIs were merged into a single platform which is now fully open source. Recently, though shipments of Symbian devices have increased, the operating system's worldwide market share has declined from over 50% to just over 40% from 2009 to 2010. Nokia handed the development of Symbian to Accenture, which will continue to support the platform until 2016.[13][14]
Windows Phone from Microsoft (closed source, proprietary)
On February 15th, 2010, Microsoft unveiled its next-generation mobile OS, Windows Phone 7. The new mobile OS includes a completely new over-hauled UI inspired by Microsoft's "Metro Design Language". It includes full integration of Microsoft services such as Windows Live, Zune, Xbox Live and Bing, but also integrates with many other non-Microsoft services such as Facebook and Google accounts. The new OS platform has received some positive reception from the technology press.[15][16][17]
The Apple iPad tablet computer uses a version of iOS.

Other platforms

GridOS from Fusion Garage [18]
GridOS was built using open source code from the Android kernel[19]. It is used as the operating system of the Grid 4 mobile phone and Grid 10 tablet, which are due to start shipping September 15th 2011.
QNX from RIM [7] (closed source, proprietary)
QNX is a commercial Unix-like real-time operating system, aimed primarily at the embedded systems market. The product was originally developed by Canadian company, QNX Software Systems, which was later acquired by BlackBerry-producer Research In Motion.
MeeGo from non-profit organization The Linux Foundation (open source, GPL)
At the 2010 Mobile World Congress in Barcelona, Nokia and Intel both unveiled 'MeeGo' a brand new mobile operating system which would combine the best of Moblin and the best of Maemo to create a truly open-sourced experience for users across all devices. As of 2011, Nokia has announced that it will no longer be pursuing MeeGo and will instead adopt Windows Phone 7 as its primary mobile OS. Nokia announced the Nokia N9 on June 21, 2011 at the Nokia Connection event [20] in Singapore. The phone is presumed to become available to the public in September 2011. LG announced its support for the platform. [21]
bada from Samsung Electronics (closed source, proprietary)
This is a mobile operating system being developed by Samsung Electronics. Samsung claims that bada will rapidly replace its proprietary feature phone platform, converting feature phones to smartphones.The name 'bada' is derived from 바다, the Korean word for ocean or sea. The first device to run bada is called 'Wave' and was unveiled to the public at Mobile World Congress 2010. The Wave is a fully touchscreen phone running the new mobile operating system. With the phone, Samsung also released an app store, called Samsung Apps, to the public. It has close to 3000[22] mobile applications.
Samsung has said that they don't see Bada as a smartphone platform, but as a platform with a kernel configurable architecture, which allows the use of either a proprietary real-time operating system, or the Linux kernel. Though Samsung plans to install bada on many phones, the company still has a large lineup of Android phones.
Linux operating system (open source, GPL) [7]
Linux is strongest in China where it is used by Motorola, and in Japan, used by DoCoMo.[23][24] Rather than being a platform in its own right, Linux is used as a basis for a number of different platforms developed by several vendors, including Android, GridOS, B2G, LiMo, Maemo, MeeGo, Openmoko and Qt Extended, which are mostly incompatible.[25][26] PalmSource (now Access) is moving towards an interface running on Linux.[27] Another platform based on Linux is being developed by Motorola, NEC, NTT DoCoMo, Panasonic, Samsung, and Vodafone.[28]
Brew from Qualcomm
Brew is used by a some mobile phone manufacturers and mobile networks, however most often the end-user does not know this since mobile phones running Brew most often lack any Brew branding. Brew runs in the background with the custom "skins" of the mobile phone manufacturer or operator on-top. Brew is used by Sprint Nextel, metroPCS, U.S. Cellular and Verizon in the US and by the Three network in much of Europe, the UK and Australia on many mobile phones produced especially for their network. Manufacturers such as Huawei, INQ Mobile, Amoi, and Samsung Mobile amongst others use Brew in some of their mobile phones and it is featured in Three UK phones such as the 3 Skypephone, INQ1 and Huawei u7510 (3 Touch). Two of HTC's mobile phones use Brew's successor Brew MP.

Historical platforms

Maemo from Nokia (open source, GPL)
Maemo is a software platform developed by Nokia for smartphones and Internet Tablets. It is based on the Debian operating system.
Maemo is mostly based on open source code, and has been developed by Maemo Devices within Nokia in collaboration with many open source projects such as the Linux kernel, Debian and GNOME.
Maemo is based on Debian GNU/Linux and draws much of its 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.
Windows Mobile from Microsoft[7][29] (closed source, proprietary)
The Windows CE operating system and Windows Mobile middleware are widely spread in Asia. The two improved variants of this operating system, Windows Mobile 6 Professional (for touch screen devices) and Windows Mobile 6 Standard, were unveiled in February 2007. It has been criticized for having a user interface which is not optimized for touch input by fingers; instead, it is more usable with a stylus. However, unlike iPhone OS, it does support both touch screen and physical keyboard configurations.
Windows Mobile's market share has sharply declined in recent years to just 5% in Q2 of 2010.[30] Microsoft is phasing out the Windows Mobile OS to specialized markets and is instead focusing on it's new platform, Windows Phone.
Palm OS/Garnet OS from Access Co. (closed source, proprietary)
webOS was introduced by Palm in January 2009 as the successor to Palm OS with Web 2.0 technologies, open architecture, and multitasking capabilities.
webOS from HP (certain parts open sourced)
webOS is a proprietary mobile operating system running on the Linux kernel, initially developed by Palm, which was later acquired by HP. HP released two phones (the Veer and the Pre 3) and a tablet (the TouchPad) running webOS in 2011 before being discontinued.
As of August 18th 2011, HP officially discontinued operations for webOS devices, due to poor market performance.[31]

Future platforms

Boot 2 Gecko[32] from non-profit organization Mozilla Foundation (open source, GPL)
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."[33]
