Symbian

The Symbian platform, including Symbian OS, or shortened to Symbian [ sɪmbɪən ], is an operating system (OS from English Operating System) for smartphones and PDAs. Predecessor is not open source EPOC. The support by the end of 2012 Nokia was completely stopped.

The mobile phone OS Symbian has its origins in the 32 -bit EPOC platform Psion; this was used in a 1998 gegründetem consortium named by the Symbian mobile phone company Ericsson, Motorola, Nokia and Psion and developed. Later, other companies such as Samsung put an operating system for their mobile phones. The Symbian Ltd.. ten years later was completely taken over by Nokia and successively transferred to a nonprofit organization, the Symbian Foundation. Nokia acquired in December 2008, all rights and transferred them to the Symbian Foundation. This declared Symbian in February 2010 for an open source solution. The Foundation took care of almost a year to the development of the operating system as well as cooperation between open source developers and internal Symbian developers. On 17 December 2010, the Symbian Foundation announced that the source code of the Symbian platform will no longer be provided for free download available. Since 1 April 2011, the Symbian code is available again and is under a separate, Symbian License this license, which is not largely compatible with open source licenses.

Symbian has much in common with desktop operating systems, such as preemptive multitasking, multithreading and memory protection. In addition to programs in C , Java and Flash Lite can be used on the devices among other OPL or Python. Support for relational databases in the implementation of SQLite is also offered.

History

On 24 June 2008 Nokia, Sony Ericsson, Motorola and NTT DoCoMo announced the intention to Symbian OS, S60 to unite, UIQ and MOAP (S ) to a single open platform. Together with AT & T, LG Electronics, Samsung Electronics, STMicroelectronics, Texas Instruments and Vodafone D2 they founded to strengthen the attractiveness of the combined software platform, the Symbian Foundation. The membership of this non-profit Foundation was open to all organizations for an annual fee. The source code has been fully released as open source.

Initially implemented by the major manufacturers only Nokia, Siemens and Sony Ericsson on this platform. These were followed by mobile phones with Symbian OS of Arima, BenQ, Lenovo, Panasonic, Samsung, LG, Motorola and Sendo. First mobile phone with Symbian OS was the Nokia 9210 Communicator, then with the version 6.0. The Motorola A920 was the first Symbian OS phone for UMTS networks.

In September 2010 rates announced both Samsung and Sony Ericsson to refrain in future smartphones based on Symbian.

In November 2010, Nokia and the Symbian Foundation announced after the departure of Sony Ericsson and Samsung from the foundation that the management and development of the platform from April 2011 will be completely at Nokia. The Symbian Foundation 'll take it from there only the licensing of the platform.

Already in February 2011, however, the present in a crisis Nokia Group announced that it will continue to equip its smartphones, especially with the operating system Windows Phone 7 from Microsoft. The smartphone market is expected to Symbian after this step only play a significant lesser role than previously thought.

In January 2013, no cell phones Nokia with Symbian announced to produce more.

Technology and versions

User interfaces

In contrast to previous Symbian OS, the additional user interface ( UI) (either S60, UIQ and MOAP ( s ) ) needed, the Symbian platform includes a UI component. Originally, this component should be 4 based on the Qt - based interface orbit from version Symbian ^. According to announcements by Nokia in October 2010, the changes are developed directly in Qt, Orbit is no longer used.

Nokia saw touchscreens before 2008 to be too expensive and fragile and therefore set up to then mainly on surfaces with pure keyboard operation. Since 2008 smartphones based on Symbian S60 v5 and operated by touch screen (eg Nokia N97, Nokia 5800 XpressMusic, Samsung i8910 HD and Sony Ericsson Satio ). End of 2010, the first touchscreen devices appeared with the completely open source Symbian ^ 3 platform ( and Others Nokia N8), on the last time an evolved form of S60 comes for touch screens for use.

Security

The ubiquity of Symbian OS Symbian is also targeted by virus writers. Although mobile malware as " Skulls " or " ComWarrior " have only a fairly small damage potential, but seem to be the producer of anti-virus programs such as F -Secure or Kaspersky Lab here to see an increasingly interesting market.

By implementing a certification system in Symbian OS Version 9.x to run unwanted code has been significantly restricted. Programs can not be installed without a valid certificate of SymbianSigned because each installation package must be digitally signed. As a result, cracked or contaminated with virus software no longer be installed without detours on the mobile device. Thus, a possible spread of viruses is a tie been advanced and operation of antivirus software on the devices in question uninteresting.

The " Curse of Silence" was a weak point of the entire Symbian OS (Symbian v9.3 excluded). So let be generated by simple or multiple sending a text message as an e -mail with a sender determines long a buffer overflow. This had the consequence that a receiving messages impossible. The user of the phone perceives no reception of this message.

History (from 2008)

Symbian ^ 1, the first version is the base of the platform and as such no actual publication of the Symbian Foundation. This version includes the "old" Symbian OS and S60 5th Edition ( Symbian OS which is based on 9.4); it is not available as open source.

Symbian ^ 2 was the first version of the platform for which no license fee is required. Although portions of Symbian ^ 2 are licensed under the EPL, the majority of the source code is under the protected SFL license and is only for members of the Symbian Foundation accessible. On 1 June 2010, several Japanese companies, including NTT DoCoMo and Sharp announced smartphones using Symbian ^ 2 for the Japanese market.

Symbian ^ 3 was announced on February 15, 2010. This version is the first fully open source version available of the platform, after the entire code base was disclosed in early February 2010. Symbian ^ 3 includes several new features, such as support for HDMI recording and output, a new 2D and 3D graphics architecture and user interface enhancements for easier operation. Menus are now accessible using simple touch ( previous versions required some two clicks) and up to three customizable home screens. The release of Symbian ^ 3 SDK was planned for October 2010 and in May 2011.

The first phones with the open source version of the platform Symbian ^ 3 smartphones; four of these devices have been (as of September 2010) Nokia announced yet for 2010: The Nokia N8, the C6-01, C7 and E7.

Symbian ^ 4 was expected according to original plans for the first half of 2011. Core of Symbian ^ 4 should be a completely redesigned user interface based on Qt. On 21 October 2010 Nokia announced the Symbian platform for its devices no longer in big version jumps ( such as the move from Symbian ^ 3 to Symbian ^ 4) develop, but in smaller pieces that smartphone owners by update immediately available are provided. As an example, the complete overhaul of the user interface was called, which was originally only with Symbian ^ 4 devices should be introduced, is also already come for Symbian ^ 3 devices in the present state, however. Accordingly, Nokia will no longer speak of Symbian ^ 3 or Symbian ^ 4, but only from the platform as a whole. The basis for this development, which will operate in addition to Symbian and Meego, Qt is. With the transition of development and management of the platform from the Symbian Foundation on Nokia which will be the future development plan for the platform where the superscript version numbers are obsolete as of Symbian ^ 3.

Task by Nokia

In the blog Engadget.com leaked internal memo dated February 2011, the Nokia CEO Stephen Elop Nokia compared with a " burning oil platform " from which one could only save themselves by jumping into the cold water. In it, he argued that the development of Symbian is becoming increasingly difficult with the growing user requirements and so you further and further behind fall behind the competitors. In a keynote speech at the conference Uplinq Qualcomm in June 2011, he explained this in more detail in the following words:

"I am an engineer with a focus on software. One of the things that were clear to me and the team was that Symbian faced challenges - some engineering challenges. While it has served us very well for a few years, something has happened. As a developer, you know how this can be done in a source code - about the time he begins to be fragile, he is a little bit worse. Every time one makes a change, it takes a bit longer to stabilize him. This is done with Symbian for several years, and it was clear that it took longer and longer to make critical changes in order to remain competitive. So we were very, very concerned about the prospect of Symbian. "

In October 2013 it was announced that from 1 January 2014 no new apps and updates to Symbian in the Nokia Store more can be submitted, but any existing apps are preserved.
