The Symbian OS platform is formed of two components: one being the
The Symbian Foundation disintegrated in late 2010 and Nokia took back control of the OS development.[15][16] In February 2011, Nokia, by then the only remaining company still supporting Symbian outside Japan, announced that it would use Microsoft's Windows Phone 7 as its primary smartphone platform, while Symbian would be gradually wound down.[17][18] Two months later, Nokia moved the OS to proprietary licensing, only collaborating with the Japanese OEMs[19] and later outsourced Symbian development to Accenture.[6][20] Although support was promised until 2016, including two major planned updates, by 2012 Nokia had mostly abandoned development and most Symbian developers had already left Accenture,[21] and in January 2014 Nokia stopped accepting new or changed Symbian software from developers.[22] The Nokia 808 PureView in 2012 was officially the last Symbian smartphone from Nokia.[23] NTT DoCoMo continued releasing OPP(S) (Operator Pack Symbian, successor of MOAP) devices in Japan, which still act as middleware on top of Symbian.[24] Phones running this include the F-07F from Fujitsu and SH-07F from Sharp in 2014.
History
Symbian originated from
Afterwards, different
etc.).With no major competition in the smartphone OS then (Palm OS and Windows Mobile were comparatively small players), Symbian reached as high as 67% of the global smartphone market share in 2006.[25]
Despite its sizable market share then, Symbian was at various stages difficult to develop for: First (at around early-to-mid-2000s) due to the complexity of then the only native programming languages Open Programming Language (OPL) and Symbian C++, and of the OS; then the stubborn developer bureaucracy, along with high prices of various integrated development environments (IDEs) and software development kits (SDKs), which were prohibitive for independent or very small developers; and then the subsequent fragmentation, which was in part caused by infighting among and within manufacturers, each of which also had their own IDEs and SDKs. All of this discouraged third-party developers, and served to cause the native app ecosystem for Symbian not to evolve to a scale later reached by Apple's App Store or Android's Google Play.
By contrast, iPhone OS (renamed iOS in 2010) and Android had comparatively simpler design, provided easier and much more centralized infrastructure to create and obtain third-party apps, offered certain developer tools and programming languages with a manageable level of complexity, and having abilities such as multitasking and graphics to meet future consumer demands.
Although Symbian was difficult to program for, this issue could be worked around by creating Java Mobile Edition apps, ostensibly under a "write once, run anywhere" slogan.[26] This wasn't always the case because of fragmentation due to different device screen sizes and differences in levels of Java ME support on various devices.
In June 2008,
Nokia became the major contributor to Symbian's code, since it then possessed the development resources for both the Symbian OS core and the user interface. Since then Nokia maintained its own code repository for the platform development, regularly releasing its development to the public repository.[28] Symbian was intended to be developed by a community led by the Symbian Foundation, which was first announced in June 2008 and which officially launched in April 2009. Its objective was to publish the source code for the entire Symbian platform under the EPL. This was accomplished on 4 February 2010; the Symbian Foundation reported this event to be the largest codebase moved to Free software in history.[27][29]
However, some important components within Symbian OS were licensed from third parties, which prevented the foundation from publishing the full source under EPL immediately; instead much of the source was published under a more restrictive Symbian Foundation License (SFL) and access to the full source code was limited to member companies only, although membership was open to any organisation.[30] Also, the Free software Qt framework was introduced to Symbian in 2010, as the primary upgrade path to MeeGo, which was to be the next mobile operating system to replace and supplant Symbian on high-end devices; Qt was by its nature free and very convenient to develop with. Several other frameworks were deployed to the platform, among them Standard C and C++, Python, Ruby, and Adobe Flash Lite. IDEs and SDKs were developed and then released for free, and application software (app) development for Symbian picked up.
In November 2010, the Symbian Foundation announced that due to changes in global economic and market conditions (and also a lack of support from members such as
With market share sliding from 39% in Q32010 to 31% in Q42010,[32] Symbian was losing ground to iOS and Android quickly, eventually falling behind Android in Q42010.[33] Stephen Elop was appointed the CEO of Nokia in September 2010, and on 11 February 2011, he announced a partnership with Microsoft that would see Nokia adopt Windows Phone as its primary smartphone platform,[34] and Symbian would be gradually phased out, together with MeeGo.[18] As a consequence, Symbian's market share fell, and application developers for Symbian dropped out rapidly. Research in June 2011 indicated that over 39% of mobile developers using Symbian at the time of publication were planning to abandon the platform.[35]
By 5 April 2011, Nokia ceased to make free any portion of the Symbian software and reduced its collaboration to a small group of preselected partners in Japan.[5] Source code released under the original EPL remains available in third party repositories,[36] including a full set of all public code from the project as of 7 December 2010.[37]
On 22 June 2011, Nokia made an agreement with Accenture for an outsourcing program. Accenture will provide Symbian-based software development and support services to Nokia through 2016.[20] The transfer of Nokia employees to Accenture was completed on 30 September 2011 and 2,800 Nokia employees became Accenture employees as of October 2011.[6]
Nokia terminated its support of software development and maintenance for Symbian with effect from 1 January 2014, thereafter refusing to publish new or changed Symbian applications or content in the Nokia Store and terminating its 'Symbian Signed' program for software certification.[38]
Features
User interface
Symbian has had a native graphics toolkit since its inception, known as AVKON (formerly known as Series 60). S60 was designed to be manipulated by a keyboard-like interface metaphor, such as the ~15-key augmented telephone keypad, or the mini-QWERTY keyboards. AVKON-based software is binary-compatible with Symbian versions up to and including Symbian^3.
Symbian^3 includes the Qt framework, which is now the recommended user interface toolkit for new applications. Qt can also be installed on older Symbian devices.
Symbian^4 was planned to introduce a new GUI library framework specifically designed for a touch-based interface, known as "UI Extensions for Mobile" or UIEMO (internal project name "Orbit"), which was built on top of Qt Widget; a preview was released in January 2010, however in October 2010 Nokia announced that Orbit/UIEMO had been cancelled.
Nokia later recommended that developers use Qt Quick with QML, the new high-level declarative UI and scripting framework for creating visually rich touchscreen interfaces that allowed development for both Symbian and MeeGo; it would be delivered to existing Symbian^3 devices as a Qt update. When more applications gradually feature a user interface reworked in Qt, the legacy S60 framework (AVKON) would be deprecated and no longer included with new devices at some point, thus breaking binary compatibility with older S60 applications.[39][40]
Browser
Symbian^3 and earlier have a built-in
Nokia released a new browser with the release of Symbian Anna with improved speed and an improved user interface.[42]
Multiple language support
Symbian had strong localization support enabling manufacturers and 3rd party application developers to localize Symbian based products to support global distribution. Nokia made languages available in the device, in language packs: a set of languages which cover those commonly spoken in the area where a device variant is to be sold. All language packs have in common English, or a locally relevant dialect of it. The last release, Symbian Belle, supports these 48 languages, with [dialects], and (scripts):

Application development
From 2010, Symbian switched to using standard C++ with Qt as the main SDK, which can be used with either Qt Creator or Carbide.c++. Qt supports the older Symbian/S60 3rd (starting with Feature Pack 1, a.k.a. S60 3.1) and Symbian/S60 5th Edition (a.k.a. S60 5.01b) releases, as well as the new Symbian platform. It also supports Maemo and MeeGo, Windows, Linux and Mac OS X.[43][44]
Alternative application development can be done using
Symbian OS previously used a Symbian specific C++ version, along with CodeWarrior and later Carbide.c++ integrated development environment (IDE), as the native application development environment.
Web Run time (WRT) is a portable application framework that allows creating widgets on the S60 Platform; it is an extension to the S60 WebKit based browser that allows launching multiple browser instances as separate JavaScript applications.[45][46]
Application development
Qt
As of 2010, the SDK for Symbian is standard C++, using Qt. It can be used with either Qt Creator, or Carbide (the older IDE previously used for Symbian development).[43][47] A phone simulator allows testing of Qt apps. Apps compiled for the simulator are compiled to native code for the development platform, rather than having to be emulated.[48] Application development can either use C++ or QML.
Symbian C++
As Symbian OS is written in C++ using Symbian Software's coding standards, it is possible to develop using Symbian C++, although it is not a standard implementation. Before the release of the Qt SDK, this was the standard development environment. There were multiple platforms based on Symbian OS that provided software development kits (SDKs) for application developers wishing to target Symbian OS devices, the main ones being UIQ and S60. Individual phone products, or families, often had SDKs or SDK extensions downloadable from the maker's website too.
The SDKs contain documentation, the header files and library files needed to build Symbian OS software, and a Windows-based emulator ("WINS"). Up until Symbian OS version 8, the SDKs also included a version of the
Symbian OS 9 and the Symbian platform use a new application binary interface (ABI) and needed a different compiler. A choice of compilers is available including a newer version of GCC (see external links below).
Symbian C++ programming has a steep learning curve, as Symbian C++ requires the use of special techniques such as descriptors, active objects and the cleanup stack. This can make even relatively simple programs initially harder to implement than in other environments. It is possible that the techniques, developed for the much more restricted mobile hardware and compilers of the 1990s, caused extra complexity in source code because programmers are required to concentrate on low-level details instead of more application-specific features. As of 2010, these issues are no longer the case when using standard C++, with the Qt SDK.
Symbian C++ programming is commonly done with an
Other languages
Symbian devices can also be programmed using
Visual Basic programmers can use NS Basic to develop apps for S60 3rd Edition and UIQ 3 devices.
In the past,
Crossfire, a plug-in for Microsoft Visual Studio. On 13 March 2007 AppForge ceased operations; Oracle purchased the intellectual property, but announced that they did not plan to sell or provide support for former AppForge products. Net60, a .NET compact framework for Symbian, which is developed by redFIVElabs, is sold as a commercial product. With Net60, VB.NET, and C# (and other) source code is compiled into an intermediate language (IL) which is executed within the Symbian OS using a just-in-time compiler. (As of 18 January 2010, RedFiveLabs has ceased development of Net60 with this announcement on their landing page: "At this stage we are pursuing some options to sell the IP so that Net60 may continue to have a future.")There is also a version of a Borland IDE for Symbian OS. Symbian development is also possible on Linux and macOS using tools and methods developed by the community, partly enabled by Symbian releasing the source code for key tools. A plug-in that allows development of Symbian OS applications in Apple's Xcode IDE for Mac OS X was available.[50]
Nokia S60 phones can also run Python scripts when the interpreter Python for S60 is installed, with a custom made API that allows for Bluetooth support and such. There is also an interactive console to allow the user to write Python scripts directly from the phone.
Deployment
Once developed, Symbian applications need to find a route to customers' mobile phones. They are packaged in SIS files which may be installed over-the-air, via PC connect, Bluetooth or on a memory card. An alternative is to partner with a phone manufacturer and have the software included on the phone itself. Applications must be Symbian Signed for Symbian OS 9.x to make use of certain capabilities (system capabilities, restricted capabilities and device manufacturer capabilities).[51] Applications could be signed for free in 2010.[52]
Architecture
Technology domains and packages
Symbian's design is subdivided into technology domains,[53] each of which comprises a set of software packages.[54] Each technology domain has its own roadmap, and the Symbian Foundation has a team of technology managers who manage these technology domain roadmaps.
Every package is allocated to exactly one technology domain, based on the general functional area to which the package contributes and by which it may be influenced. By grouping related packages by themes, the Symbian Foundation hopes to encourage a strong community to form around them and to generate discussion and review.
The Symbian System Model[55] illustrates the scope of each of the technology domains across the platform packages.
Packages are owned and maintained by a package owner, a named individual from an organization member of the Symbian Foundation, who accepts code contributions from the wider Symbian community and is responsible for package.

Design
Symbian features
Symbian OS was created with three systems design principles in mind:
- the integrity and security of user data is paramount
- user time must not be wasted
- all resources are scarce
To best follow these principles, Symbian uses a microkernel, has a request-and-callback approach to services, and maintains separation between user interface and engine. The OS is optimised for low-power battery-based devices and for read-only memory (ROM)-based systems (e.g. features like XIP and re-entrancy in shared libraries). The OS, and application software, follows an object-oriented programming design named model–view–controller (MVC).
Later OS iterations diluted this approach in response to market demands, notably with the introduction of a real-time kernel and a platform security model in versions 8 and 9.
There is a strong emphasis on conserving resources which is exemplified by Symbian-specific programming idioms like
Operating system
The All over Model contains the following layers, from top to bottom:
- UI Framework Layer
- Application Services Layer
- Java ME
- OS Services Layer
- generic OS services
- communications services
- multimedia and graphics services
- connectivity services
- Base Services Layer
- Kernel Services & Hardware Interface Layer
The Base Services Layer is the lowest level reachable by user-side operations; it includes the
Symbian has a
Symbian is designed to emphasise compatibility with other devices, especially removable media file systems. Early development of EPOC led to adopting File Allocation Table (FAT) as the internal file system, and this remains, but an object-oriented persistence model was placed over the underlying FAT to provide a POSIX-style interface and a streaming model. The internal data formats rely on using the same APIs that create the data to run all file manipulations. This has resulted in data-dependence and associated difficulties with changes and data migration.
There is a large networking and communication subsystem, which has three main servers called: ETEL (EPOC telephony), ESOCK (EPOC sockets) and C32 (responsible for serial communication). Each of these has a plug-in scheme. For example, ESOCK allows different ".PRT" protocol modules to implement various networking protocol schemes. The subsystem also contains code that supports short-range communication links, such as
There is also a large volume of user interface (UI) Code. Only the base classes and substructure were contained in Symbian OS, while most of the actual user interfaces were maintained by third parties. This is no longer the case. The three major UIs – S60, UIQ and MOAP – were contributed to Symbian in 2009. Symbian also contains graphics, text layout and font rendering libraries.
All native Symbian C++ applications are built up from three framework classes defined by the application architecture: an application class, a document class and an application user interface class. These classes create the fundamental application behaviour. The remaining needed functions, the application view, data model and data interface, are created independently and interact solely through their APIs with the other classes.
Many other things do not yet fit into this model – for example,
Symbian includes a reference user-interface called "TechView." It provides a basis for starting customisation and is the environment in which much Symbian test and example code runs. It is very similar to the user interface from the Psion Series 5 personal organiser and is not used for any production phone user interface.
Symbian UI variants, platforms
Symbian, as it advanced to OS version 7.0, spun off into several different
User Interfaces platforms that run on or are based on Symbian OS include:
- S60, Symbian, also called Series 60. It was backed mainly by Nokia. There are several editions of this platform, appearing first as S60 (1st Edition) on Nokia 7650. It was followed by S60 2nd Edition (e.g. Nokia N70), S60 3rd Edition (e.g. Nokia N73) and S60 5th Edition (which introduced touch UI e.g. Nokia N97). The name, S60, was changed to just Symbian after the formation of Symbian Foundation, and subsequently called Symbian^1, 2 and 3.
- Nokia 9300i.
- Series 90 Touch and button based. The only phone using this platform is Nokia 7710.
- Sony Ericsson G900. It was discontinued after the formation of Symbian Foundation, and the decision to consolidate different Symbian UI variants into one led to the adoption of S60 as the version going forward.[58]
- FOMA"Freedom of Mobile Access" network brand and is based on the UI from earlier Fujitsu FOMA models. The user cannot install new C++ applications. (Japan Only)
- FOMAphone.

▲ Software update service for Nokia Belle and Symbian (S60) phones is discontinued at the end of December 2015
In Q1 2004 2.4 million Symbian phones were shipped, double the number as in Q1 2003. Symbian Ltd. was particularly impressed by progress made in Japan.[77]
3.7 million devices were shipped in Q3 2004, a growth of 201% compared to Q3 2003 and market share growing from 30.5% to 50.2%. However, in the United States it was much less popular, with a 6% market share in Q3 2004, well behind Palm OS (43%) and Windows Mobile (25%). This has been attributed to North American customers preferring wireless PDAs over smartphones, as well as Nokia's low popularity there.[78]
On 16 November 2006, the 100 millionth smartphone running the OS was shipped.[79] As of 21 July 2009, more than 250 million devices running Symbian OS had been produced.[80]
In 2006, Symbian had 73% of the smartphone market,[81] compared with 22.1% of the market in the second quarter of 2011.[82]
By the end of May 2006, 10 million Symbian-powered phones were sold in Japan, representing 11% of Symbian's total worldwide shipments of 89 million.[83] By November 2007 the figure was 30 million, achieving a market share of 65% by June 2007 in the Japanese market.[84]
Symbian has lost market share over the years as the market has dramatically grown, with new competing platforms entering the market, though its sales have increased during the same timeframe. E.g., although Symbian's share of the global smartphone market dropped from 52.4% in 2008 to 47.2% in 2009, shipments of Symbian devices grew 4.8%, from 74.9 million units to 78.5 million units.[85] From Q2 2009 to Q2 2010, shipments of Symbian devices grew 41.5%, by 8.0 million units, from 19,178,910 units to 27,129,340; compared to an increase of 9.6 million units for Android, 3.3 million units for RIM, and 3.2 million units for Apple.[86]
Prior reports on device shipments as published in February 2010 showed that the Symbian devices formed a 47.2% share of the smart mobile devices shipped in 2009, with
In the number of "smart mobile device" sales, Symbian devices were the market leaders for 2010. Statistics showed that Symbian devices formed a 37.6% share of smart mobile devices sold, with
Over the course of 2009–10,
In Q2 2012, according to IDC worldwide market share has dropped to an all-time low of 4.4%.[93]
Criticism
The users of Symbian in the countries with non-Latin alphabets (such as Russia, Ukraine and others) have been criticizing the complicated method of language switching for many years.[94] For example, if a user wants to type a Latin letter, they must call the menu, click the languages item, use arrow keys to choose, for example, the English language from among many other languages, and then press the 'OK' button. After typing the Latin letter, the user must repeat the procedure to return to their native keyboard. This method slows down typing significantly. In touch-phones and QWERTY phones the procedure is slightly different but remains time-consuming. All other mobile operating systems, as well as Nokia's S40 phones, enable switching between two initially selected languages by one click or a single gesture.
Early versions of the firmware for the original
In November 2010, Smartphone blog All About Symbian criticized the performance of
There are many different versions and editions of Symbian, which led to fragmentation. Apps and software may be incompatible when installed across different versions of Symbian.[98]
Malware
Symbian OS is subject to a variety of viruses, the best known of which is
However, with a view that the average mobile phone user shouldn't have to worry about security, Symbian OS 9.x adopted a Unix-style capability model (permissions per process, not per object). Installed software is theoretically unable to do damaging things (such as costing the user money by sending network data) without being digitally signed – thus making it traceable. Commercial developers who can afford the cost can apply to have their software signed via the Symbian Signed program. Developers also have the option of self-signing their programs. However, the set of available features does not include access to Bluetooth, IrDA, GSM CellID, voice calls, GPS and few others. Some operators opted to disable all certificates other than the Symbian Signed certificates.
Some other hostile programs are listed below, but all of them still require the input of the user to run.
- Drever.A is a malicious SIS file trojan that attempts to disable the automatic startup from Simworks and Kaspersky Symbian Anti-Virus applications.
- Locknut.B is a malicious SIS file trojan that pretends to be a patch for Symbian S60 mobile phones. When installed, it drops[clarification needed] a binary that will crash a critical system service component. This will prevent any application from being launched in the phone.
- Mabir.A is basically Cabir with added MMS functionality. The two are written by the same author,[citation needed] and the code shares many similarities. It spreads using Bluetoothvia the same routine as early variants of Cabir. As Mabir.A activates, it will search for the first phone it finds, and starts sending copies of itself to that phone.
- Fontal.A is an SIS file trojan that installs a corrupted file which causes the phone to fail at reboot. If the user tries to reboot the infected phone, it will be permanently stuck on the reboot screen, and cannot be used without disinfection – that is, the use of the reformat key combination which causes the phone to lose all data. Being a trojan, Fontal cannot spread by itself – the most likely way for the user to get infected would be to acquire the file from untrusted sources, and then install it to the phone, inadvertently or otherwise.
A new form of malware threat to Symbian OS in the form of 'cooked firmware' was demonstrated at the International Malware Conference,
Bypassing platform security
Symbian OS 9.x devices can be hacked to remove the platform security introduced in OS 9.1 onwards, allowing users to execute unsigned code.
Version history
Version | Description |
---|---|
EPOC16 | EPOC16, originally simply named EPOC, was the operating system developed by Psion in the late 1980s and early 1990s for Psion's "SIBO" (SIxteen Bit Organisers) devices. All EPOC16 devices featured an Series 3 (1991–98), Series 3a, Series 3c, Series 3mx, Siena, Workabout, and Workabout mx. The MC400 and MC200, the first EPOC16 devices, shipped in 1989.
EPOC16 featured a primarily monochrome, keyboard-operated graphical interface[103] – the hardware for which it was designed originally had pointer input in the form of a digitiser panel. In the late 1990s, the operating system was referred to as EPOC16 to distinguish it from Psion's then-new EPOC32 OS. |
EPOC32 (releases 1 to 5) | The first version of EPOC32, Release 1 appeared on the Psion and netPad (which all featured Release 5).
The EPOC32 operating system, at the time simply referred to as EPOC, was later renamed Symbian OS. Adding to the confusion with names, before the change to Symbian, EPOC16 was often referred to as SIBO to distinguish it from the "new" EPOC. Despite the similarity of the names, EPOC32 and EPOC16 were completely different operating systems, EPOC32 being written in C++ from a new codebase with development beginning during the mid-1990s. EPOC32 was a pre-emptive multitasking, single user operating system with memory protection, which encourages the application developer to separate their program into an engine and an interface. The Psion line of PDAs come with a graphical user interface called EIKON which is specifically tailored for handheld machines with a keyboard (thus looking perhaps more similar to desktop GUIs than palmtop GUIs[104]). However, one of EPOC's characteristics is the ease with which new GUIs can be developed based on a core set of GUI classes, a feature which has been widely explored from Ericsson R380 and onwards.
EPOC32 was originally developed for the , but can be compiled towards target devices using several other processor types.During the development of EPOC32, Psion planned to license EPOC to third-party device manufacturers, and spin off its software division as Psion Software. One of the first licensees was the short-lived Geofox, which halted production with less than 1,000 units sold. Ericsson marketed a rebranded Psion Series 5mx called the MC218, and later created the EPOC Release 5.1 based smartphone, the R380. Oregon Scientific also released a budget EPOC device, the Osaris (notable as the only EPOC device to ship with Release 4). Work started on the 32-bit version in late 1994. The Series 5 device, released in June 1997, used the first iterations of the EPOC32 OS, codenamed "Protea", and the "Eikon" graphical user interface.
The Oregon Scientific Osaris was the only PDA to use the ER4. The Ericsson MC218 were released in 1999 using ER5. A phone project was announced at CeBIT , the Phillips Illium/Accent, but did not achieve a commercial release. This release has been retrospectively dubbed Symbian OS 5.
The first phone using ER5u, the Ericsson R380 was released in November 2000. It was not an open device: software could not be installed. Notably, several never-released Psion prototypes for next generation PDAs, including a Bluetooth Revo successor codenamed Conan, were using ER5u. The 'u' in the name refers to it supporting Unicode. In June 1998, Psion Software became . As of Release 6, EPOC was renamed Symbian OS. |
Symbian OS 6.0 and 6.1 | The OS was renamed Symbian OS and envisioned as the base for a new range of smartphones. This release is sometimes called ER6. Psion gave 130 key staff to the new company and retained a 31% shareholding in the spin-off.
The first 'open' Symbian OS phone, the Nokia 9210 Communicator, was released in June 2001. Bluetooth support was added. Almost 500,000 Symbian phones were shipped in 2001, rising to 2.1 million the following year.
Development of different UIs was made generic with a "reference design strategy" for either 'smartphone' or 'communicator' devices, subdivided further into keyboard- or tablet-based designs. Two reference UIs (DFRDs or Device Family Reference Designs) were shipped: Quartz and Crystal. The former was merged with Ericsson's Ronneby design and became the basis for the UIQ interface; the latter reached the market as the Nokia Series 80 UI. Later DFRDs were Sapphire, Ruby, and Emerald. Only Sapphire came to market, evolving into the Pearl DFRD and finally the Nokia Series 60 UI, a keypad-based 'square' UI for the first true smartphones. The first one of them was the Nokia 7650 smartphone (featuring Symbian OS 6.1), which was also the first with a built-in camera, with VGA (0.3 Mpx = 640×480) resolution. Other notable S60 Symbian 6.1 devices are the Nokia 3650, the short lived Sendo X and Siemens SX1 , the first and the last Symbian phone from Siemens.
Despite these efforts to be generic, the UI was clearly split between competing companies: Crystal or Sapphire was Nokia, Quartz was Ericsson. DFRD was abandoned by Symbian in late 2002, as part of an active retreat from UI development in favour of headless delivery. Pearl was given to Nokia, Quartz development was spun off as UIQ Technology AB, and work with Japanese firms was quickly folded into the MOAP standard. |
Symbian OS 7.0 and 7.0s | First shipped in 2003. This is an important Symbian release which appeared with all contemporary user interfaces including pJava and JavaPhone to one based on the Java ME standard.
One million Symbian phones were shipped in Q1 2003, with the rate increasing to one million a month by the end of 2003. Symbian OS 7.0s was a version of 7.0 special adapted to have greater backward compatibility with Symbian OS 6.x, partly for compatibility between the Communicator 9500 and its predecessor the Communicator 9210. In 2004, Psion sold its stake in Symbian. The same year, the first Symbian OS threats .
|
Symbian OS 8.0 | First shipped in 2004, one of its advantages would have been a choice of two different kernels (EKA1 or EKA2). However, the EKA2 kernel version did not ship until Symbian OS 8.1b. The kernels behave more or less identically from user-side, but are internally very different. EKA1 was chosen by some manufacturers to maintain compatibility with old device drivers, while EKA2 was a real-time kernel. 8.0b was deproductised in 2003.
Also included were new APIs to support vector graphics and direct screen access.
|
Symbian OS 8.1 | An improved version of 8.0, this was available in 8.1a and 8.1b versions, with EKA1 and EKA2 kernels respectively. The 8.1b version, with EKA2's single-chip phone support but no additional security layer, was popular among Japanese phone companies desiring the real-time support but not allowing open application installation.
The first and maybe the most famous smartphone featuring Symbian OS 8.1a was Nseries .
|
Symbian OS 9.0 | Symbian OS 9.0 was used for internal Symbian purposes only. It was de-productised in 2004. 9.0 marked the end of the road for EKA1. 8.1a is the final EKA1 version of Symbian OS.
Symbian OS has generally maintained reasonable binary code compatibility . In theory the OS was BC from ER1-ER5, then from 6.0 to 8.1b. Substantial changes were needed for 9.0, related to tools and security, but this should be a one-off event. The move from requiring ARMv4 to requiring ARMv5 did not break backwards compatibility.
|
Symbian OS 9.1 | Released early 2005. It includes many new security related features, including platform security module facilitating S60 platform 3rd Edition phones have Symbian OS 9.1. Sony Ericsson is shipping the M600 and P990 based on Symbian OS 9.1. The earlier versions had a defect where the phone hangs temporarily after the owner sent a large number of SMS'es. However, on 13 September 2006, Nokia released a small program to fix this defect.[105] Support for Bluetooth 2.0 was also added.
Symbian 9.1 introduced capabilities and a Platform Security framework. To access certain APIs, developers have to sign their application with a digital signature. Basic capabilities are user-grantable and developers can self-sign them, while more advanced capabilities require certification and signing via the Symbian Signed program, which uses independent 'test houses' and phone manufacturers for approval. For example, file writing is a user-grantable capability while access to Multimedia Device Drivers require phone manufacturer approval. A TC TrustCenter ACS Publisher ID certificate is required by the developer for signing applications. |
Symbian OS 9.2 | Released Q1 2006. Support for S60 3rd Edition Feature Pack 1 phones have Symbian OS 9.2.
Nokia phones with Symbian OS 9.2 OS include the Nokia 5700 .
|
Symbian OS 9.3 | Released on 12 July 2006. Upgrades include improved memory management and native support for Wifi and others feature Symbian OS 9.3. |
Symbian OS 9.4 | Announced in March 2007. Provides the concept of demand paging which is available from v9.3 onwards. Applications should launch up to 75% faster. Additionally, Nokia X6, Sony Ericsson Satio, Sony Ericsson Vivaz , and Sony Ericsson Vivaz Pro.
Used as the basis for Symbian^1, the first Symbian platform release. The release is also better known as S60 5th edition , as it is the bundled interface for the OS.
|
Symbian^2 | Symbian^2 is a version of Symbian that only used by Japanese manufacturers[citation needed], started selling in Japan market since May 2010.[106] The version is not used by Nokia.[107] |
Symbian^3 (Symbian OS 9.5) and Symbian Anna | Symbian^3 is an improvement over previous S60 5th Edition and features single touch menus in the user interface, as well as new Symbian OS kernel with hardware-accelerated graphics; further improvements will come in the first half of 2011 including portrait qwerty keyboard, a new browser and split-screen text input. Nokia announced that updates to Symbian^3 interface will be delivered gradually, as they are available; Symbian^4, the previously planned major release, is now discontinued and some of its intended features will be incorporated into Symbian^3 in successive releases, starting with Symbian Anna. |
Nokia Belle (Symbian OS 10.1) | In the summer of 2011 videos showing an early leaked version of Symbian Belle (original name of Nokia Belle) running on a Nokia N8 were published on YouTube.[108]
On 24 August 2011, Nokia announced it officially for three new smartphones, the Nokia 600 (later replaced by Nokia 603), Nokia 700, and Nokia 701.[109] Nokia officially renamed Symbian Belle to Nokia Belle in a company blog post.[110][111] Nokia Belle adds to the Anna improvements with a pull-down status/notification bar, deeper near field communication integration, free-form re-sizable homescreen widgets, and six homescreens instead of the previous three. As of 7 February 2012, Nokia Belle update is available for most phone models through Nokia Suite, coming later to Australia. Users can check the availability at the Nokia homepage.[112]
On 1 March 2012, Nokia announced a Feature Pack 1 update for Nokia Belle which will be available as an update to Nokia 603, 700, 701 (excluding others), and for Nokia 808 PureView natively. Symbian Carla and Donna were the planned follow-up releases to Belle, to be released in late 2012 and late 2013 respectively. However it was acknowledged in May 2012 that these had been cancelled and that the upcoming Belle Feature Pack 2 would be the last version of the operating system.[113] The latest software release for Nokia 1st generation Symbian Belle smartphones (Nokia N8, C7, C6-01, Oro, 500, X7, E7, E6) is Nokia Belle Refresh (111.040.1511).[114] In October 2012, the Nokia Belle Feature Pack 2, widely considered the last major update for Symbian, was released for Nokia 603, 700, 701, and 808 PureView.[115] |
