Symbian OS 9.4 operating system menu
History
Pocket computers have become more powerful over time. By 1994, the 64K limit inherent in 16-bit systems was becoming a major obstacle to software development, and it was becoming clear that a system of this class should be portable to a wider range of devices. This is how the new Symbian OS system appeared. Retaining the best features of the previous Psion OS, it was supposed to be fully 32-bit, portable to any hardware platform and architecture. This would allow Symbian OS to become open systemavailable for licensing by third-party mobile device manufacturers. For this purpose, an independent software company, Psion Software, was spun off from the Psion group. New system was to become the standard for wireless information devices through licensing to a wide range of manufacturers in the industry. In April 1997, the first version of Symbian OS was released and immediately a new product was created on its basis: Psion Series 5. Licensing of the new OS began even before its official release. Symbian OS with its efficiency and flexibility, as well as the high technical level of Symbian (formerly Psion Software) formed an extremely favorable basis for the creation of new system software for wireless devices... Psion Software was spun off from the Psion Group and changed its name to Symbian Ltd, a joint venture between Ericsson, Nokia, Motorola and Psion. From the outset, the system was designed to be fully object-oriented. C ++ was chosen as the implementation language as the most powerful and most functional object-oriented programming language to date.
October 2010: Along with the publication of positive financial results, Nokia announced a change in strategy for the development of Symbian. From now on, the platform will be updated continuously, allowing users to install updates on their existing devices.
Nokia has decided to abandon the release of Symbian ^ 4, the next version of the smartphone platform, scheduled for release in 2011. Instead, the company intends to continuously improve the current version of the platform, adding new features step by step. The new approach will allow updates to be installed on existing smartphones. That is, for example, if earlier the user would have had to wait for the release of the first mobile phones based on Symbian ^ 4 to see this platform in action, now he can buy Nokia N8 and wait for the corresponding update, writes Ars Technica. In the future, there will be no separate Symbian versions (^ 4, ^ 5, etc.), just the Symbian platform will remain.
In addition, Nokia announced its intention to use the framework for developing applications Qt as the main one, both for Symbian and for its other platform - MeeGo. This is expected to improve graphical interface mobile devices and improve the quality of the user experience in general - to change what Nokia loses most to other vendors.
Nokia representatives assured that the company will try to save users from fragmentation (presence a large number versions of the platform with which you want to achieve compatibility). It is planned that all third-party software released up to a certain point will be compatible with Symbian updates that will be released in the future.
November 2010 The European Commission announced the allocation of € 11 million under the state program to promote the innovative development of the economy to support the Symbian platform. The same amount will be allocated by the SYMBEOSE consortium (Symbian - the Embedded Operating System for Europe), IntoMobile reports. In total, € 22 million will be additionally invested in the platform.
SYMBEOSE will focus on three objectives. First, the organization plans to make the development of Symbian devices easier by adapting the software for different chipsets. Secondly, the consortium will develop Symbian towards embedded solutions ( appliances, sensors, etc.). Third, research will begin in the field of multi-threaded and cloud computing and other technologies promising for the mobile device market.
SYMBEOSE consortium includes 24 manufacturers according to the official Symbian blog mobile phones, operator, software developer and research center from eight European countries. Symbian Foundation and SYMBEOSE are different organizations that will exist simultaneously and will not replace each other. The Symbian Foundation, a non-profit consortium founded by Nokia, leads the development and support of the Symbian mobile platform.

Today the smartphone market is developing at an unprecedented rate, slowly replacing the market for conventional mobile phones. If earlier only wealthy people could afford such high-performance devices, now they have become available to everyone. Their price range is comparable to prices regular phones... Manufacturers are trying to provide smartphones with the most advanced technology and at the same time also reduce their cost.
In the near future, smartphones, like their older "brothers" - communicators, will conquer the mobile device market, completely replacing conventional handsets. After buying such a device, we get a multifunctional device that combines both multimedia and an unlimited set of business functions, and is also equipped with an operating system and processor, which distinguishes it from a mobile phone.
Today, there are several types of operating systems, such as, and. Each of these OS has its own characteristics, types, advantages and disadvantages.
The most common is. Mainly due to the fact that most of the smartphones are produced by everyone's favorite manufacturer - Nokia. Although manufacturers such as Samsung, Motorola, Siemens and Sony Ericsson have mobile devices based on this OS in their arsenal. And most importantly, devices from different manufacturers, but with the same operating system, have a lot of differences.
The Symbian operating system was developed to satisfy the desires of customers to have multifunctional mobile devices and perform various high-tech operations on them.
And thanks to the efforts of such large corporations as Ericsson, Nokia, Matsushita, Kenwood, Fujitsu, Siemens, the first version of Symbian OS was released in 1997. And in 2002, the sixth version of this OS was released, and with it the first smartphone.
Today the most widespread are the 7,8 and 9 versions of Symbian. In general, Symbian is full set office, organizational and communication applications, and to control the device itself and application programs, a beautifully drawn graphical shell is used.
In general, Symbian OS has several versions, namely 3 and several add-on packages:
- S60 2nd Edition, Feature Pack 1 - Symbian OS v7.0s (, Panasonic X700, Panasonic X800, Samsung D720, Samsung D730);
- S60 2nd Edition, Feature Pack 2 - Symbian OS v8.0a (, Lenovo P930);
So, let's take a look at the latest version, namely S60 3rd Edition, Feature Pack 1 - Symbian OS v9.1, namely its main advantages and disadvantages.
Main advantages and differences from previous versions:
Improved performance indicators of the system and the speed of data access, the efficiency of working with memory;
New security platform;
No viruses at the moment;
Support for high color rendering of displays;
Main disadvantages:
Complete incompatibility with programs and applications of previous OS versions.
Conclusion: Symbian is by far the most optimal and most powerful operating system used in mobile devices... which will certainly be the leader in the smartphone market for a long time to come. Updates (Feature Pack) for Symbian 9, which will expand its capabilities, will not be long in coming. And let's hope that software manufacturers will not keep waiting long, and will release the same amount of software as for previous versions.

The latest revision of the operating system was born two years ago Symbian - it was the S60 fifth edition. It was she who was first used to work on touchscreen phones... It is clear that it is very difficult to make an ideal OS for controlling fingers or a stylus on the first try, so there was a need for a more thoughtful and perfect system that would be ideal for these purposes. new platform, which was named Symbian ^ 3. First, a little about the errors that were present in the previous version, and which had to be fixed in the new one. Firstly, it is the impossibility to select one action with just one click - often it was necessary to pre-perform several clicks in succession, and this took a lot of time. Secondly, gesture control was not implemented. Thirdly, the shell did not work as often as we would like, although in some cases this was a problem of the device itself and its processor speed and random access memory... There were also a number of minor flaws, but we considered these to be the main ones. We will now move on to a sequential description of the highlights in the new operating system. Symbian ^ 3.
Symbian ^ 3 interface implementation
Symbian ^ 3 desktop view
In the working area of \u200b\u200ba smartphone running Symbian ^ 3, there are three separate desktops. Switching between them is done by swiping left and right - just like in touchscreens. In phones Nokia you can choose a different wallpaper for each desktop.Desktops are mainly designed to accommodate numerous widgets. Nokia widgets appeared not so long ago - they were first used in the phone, and now they can be seen almost everywhere. Each of the widgets can be present simultaneously on several screens. Also, screens are intended for shortcuts to applications, remote program functions, messages, news feeds and the like. All widgets have a small drawback - even if they are designed to display text information, it cannot occupy more than two lines, which is not always convenient in some applications (for example, in a widget that displays the contents of an email box).During incoming call the screen displays a picture associated with this particular subscriber, as well as several virtual control buttons.Symbian ^ 3 phonebook implementation
While the smartphone is in standby mode, smart dialing is possible - you can select one letter, and the device will display a list of contacts that begin with this letter.Any number of record fields can be assigned to each contact; only the volume of the device's internal memory can serve as a limitation. The set of fields is standard, like on other platforms. Calls and pictures of callers can also be personalized. You can sort the fields in the phone book by either first name or last name. Subscriber groups are also implemented, each group can be assigned an individual call signal. There is also a voice call, but it takes some preparation and getting used to. This function works both for contacts recorded in both English and Russian. The phone book can be archived - in this case, this will be backup information.Symbian ^ 3 Call Lists
In Symbian ^ 3, as in other platforms, this section hides missed, sent, and received calls. The user himself can specify for what period the information on calls should be stored. You can filter the calls, view their duration and time of making.Social tools
To work with social networks in phones on Symbian ^ 3 a separate button with the same name appeared. It calls a utility that can easily find the user in those social networks, in which the owner of the device is registered. For example, it can be popular today Facebook or Twitter.
Working with messages
Symbian ^ 3 phones support the creation of text and multimedia messages, this is done centrally from a menu item named Message. As in the last samsung phones, the device is able to automatically detect the type of message after it is created, so the user does not initially need to make any choice. You can use three different font sizes when composing your message. You can display messages on the screen either in a classic way or in the form of a chat (dialogue). The client is also here emailwhich supports POP3 / IMAP4 / SMTP / MIME2 standards.Musical capabilities of Symbian ^ 3
A widget is placed on the desktop to control music playback, you need to activate it manually - after starting the player, it does not automatically turn on itself. The player itself has not changed much since the previous version of this operating system. Remained all the same features, including sorting songs by genre, artist, album, composer, creating custom playlists. Adjustments can be made using an eight-band equalizer that supports manual settings, as well as take advantage of the expanded stereo base. The bitrate of the songs during music playback is not important.Podcasts - component player, which was previously a separate program. You can open podcasts both from the main menu of the audio player, and download them from the outside. All podcasts are formed into one library, then it can be searched for or synchronized with other devices.A set of equalizers is used to adjust the music, each of which is eight-band. There are six preset values, all of which can be edited to suit your own tastes. There is also a function of expanding the stereo base and Loudness.Photographic capabilities
Implementation of work with the camera in Symbian ^ 3 implemented in almost the same way as in previous versions of this operating system. The work and viewing of photos are carried out separately, and video files are viewed separately. The gallery of photographs is presented in the form of small thumbnails; when you hover, a small window appears, in which the name of the photograph is written. There is a view function in the form of a slideshow, in which you can configure background music and paging speed. You can view images both vertically and horizontally, for scaling there is a ruler that works on the principle of "pich-to-zoom".To process the images received from the camera, you can use the built-in editor, which allows you not only to change the image using several filters, but also add pictures from the clip art, smileys, change the size and orientation of photographs.Video capabilities
There is a separate section with the same name for working with video. This includes all footage videos, and they can be classified into these categories: last viewed, last captured, YouTube videos, videos from the Ovi Store and other videos. Supported codecs include the following: H.264, MPEG-4, VC-1, Sorenson Spark VGA, Real video 10 QVGA. What is not supported is DivX / XVid, but the issue can be resolved by purchasing separate players for specific models phone.You can edit video directly using your mobile phone - add tags and titles, special effects, create a cut from different videos, make a slideshow and create a video sequence from them.In those phones that support TV, there is a separate item for these needs, here you can watch your favorite TV shows.Phone search
In the operating system Symbian ^ 3 very well thought out search system. Previously, a separate utility was responsible for this feature, but now it is an integral function of the OS. For each country, the search resource that is most popular in that country is used. Naturally, this is Yandex. Besides searching in global network, you can search inside the device in many categories, some of which are even included in the main menu.Organizer
As in previous versions, the organizer includes a calendar and a set of the following applications: converter, calculator, voice recorder, notes, clock. There is also a file manager, in which you can perform operations of copying, moving, deleting files - both on the memory card and in the internal memory of the device. Device Manager is SyncML sync. You can transfer data (phonebook contacts, calendar, etc.) from one phone to another using the Data Transfer utility.Settings
In the section with phone settings in Symbian ^ 3 you can choose one of the themes, screen saver, icon type, typing language, screen brightness, assign joystick deflections to invoke individual applications, commands for soft keys.To work on the Internet, GPRS parameters and connection security are configured.It also includes the date and time settings, auto-blocking parameters.For touch screen auto-spread options are selected, sound accompaniment this event.Browser
Browser operation in Symbian ^ 3 remained identical to previous versions of the operating system. As before, there are certain problems with memory allocation. It works on the WebKit engine (it was taken as a basis for Safari). From its settings, you can select scaling (including with fingers), storing the list of visited pages, auto-remembering visited websites, storing favorites. New links can now be opened not only in the main window, but also in a new one. Cookies, personal data of the user (login and password) are remembered. There is a separate reader for reading news.The new operating system has been improved in many ways, but much has remained “overboard”. A noticeable increase in the speed of applications, which was noted by the increased amount of memory on new devices, on which it is installed Symbian ^ 3... The negative sides include an insufficiently redesigned browser, external design (themes, icons, animation effects). The new OS cannot be called a revolutionary breakthrough - rather, it is a good work on bugs, which, nevertheless, does not deserve the highest praise.And phones are rightfully considered Symbian. Until 2008, the consortium of the same name was engaged in its development. With the sale of the full block of shares, consumer demand for the OS also expanded. The reason for this was the expansion of production and contracts with the world's leading brands.
From origins to perfection
In the mid-1990s mobile systems left much to be desired. Multimedia capabilities were minimized, the engine was monolithic, applications were limited to single banal instances (calendar, calculator, etc.). Everything changed radically in 1997, when a number of companies signed a pact on cooperation in the development of a universal operating system. This is how the Symbian consortium was founded. It was headed by the leaders of the brands Nokia, Ericsson, Psion and Motorola.
Towards the end of the 1990s, the first Symbian 5 OS was born. Its platform was supported by Psion computers, as well as Ericsson MC218 and netPad devices. Soon, the developers added the EPOC5u system to the line for Unicode integration. The turning point for the consortium came with the release of OS version 6.0. On its basis, the first branded symbian smartphone - Nokia 9210.
In the years that followed, mobile systems began to develop at an extraordinary rate. In 2003, the developers delighted users of Symbian OS 7 and its extended version. This system could support most popular platforms: UIQ, Series 60 and 80, FOMA and others. By mid-2004, Psion and Motorola unexpectedly left the consortium. However, this did not affect further production in any way. At the end of the year, Symbian 8 appeared, which could support 2-core devices.
The next OS version - 9.0 - significantly expanded the brand's influence on the global market. The latest technologies were used in the development, which no other company had. This made it possible to move away from the integration of the ESA1 core. OS 9.2 introduced the ability to work with OMA Management and Bluetooth 2. Version 9.2 supported HSDPA interface and Vietnamese hieroglyphs.
The new Symbian OS 9.4 was released in spring 2007. Its main hallmark there was support for touch control. It was also more optimized, so it was suitable for weak phones, saving battery power up to 30%. It is worth noting the accelerated interface with support for DVB-H and VoIP.
Mobile revolution and the decline of an era
In December 2008, the rights to software Symbian was taken over by Nokia. A month later, all applications and mobile phone operating systems began to be released with the Nokia prefix. First of all, the new owners of the consortium transferred the OS from the familiar S60 platform to the x86 processor. For testing we used intel system Atom.
The new operating systems were high quality and fast, but many users did not like the fact that they remained paid. In November 2009, Samsung terminated its contract with Symbian. This hit the consortium's credibility hard. This is often why the decision was made in February 2010 to make the Symbian line completely free and open source. In the autumn of the same year, Sony Ericsson also left the merger, moving to its main competitor, Android.
Gradually, sales of devices based on the OS of a well-known consortium began to be reduced to a minimum. In 2011, the official website of the brand was completed. Rumors began to circulate about the termination of the release of new OS. At the end of 2011, a new Nokia Belle axle was announced, which became the prototype of the updated Symbian. Over the next two years, OS users were content with only rare updates. In 2013, the project was transferred to support mode. Further developments are not planned in the near future.
Characteristics
OS Symbian is considered the successor to the notorious EPOC32 line, which was developed by Psion engineers in the mid-1990s for pocket computers. In 1999, most of the system underwent modernization. The developers pursued the goal of optimizing the code so that the OS would function normally even on the most weak devices.
Programmers have achieved outstanding results thanks to improved caching. This not only saves a significant amount of memory and battery power, but also speeds up applications. It's all to blame for a new approach to programming. An object-oriented method was used in the development of the architecture. Versions 9.x introduced a robust API-level protection mechanism. In addition, Symbian employees managed to differentiate RAM according to application priorities.
It is worth noting that for a long time C ++ remained the main programming language, which supported Java and the PIPS libraries. As for Nokia Symbian OS, it combines all the best qualities and characteristics of the main competitors Windows Mobile and Google Android.
Major modifications
At the moment there are several operating systems for phones based on Symbian developments. This primarily concerns UIQ. This OS is an integral part of motorola smartphones and Sony Ericsson. The main difference between this system and others is considered to be support. All rights to the OS belong to Sony.
The Series 60 system was once the backbone of all Nokia phone devices. For a long time it was licensed by such as Siemens, Samsung, LG and others. It was originally developed for phones with keyboards. A new version Series 80 has become the hallmark of the Japanese company. The platform has also been created for keyboards.
OS MOAR has gained high popularity in Asia. At the moment, this platform is used to produce products of such famous brands as Fujitsu, Sharp, Mitsubishi and Sony Ericsson.
Non-standard OS modifications are used by Nokia 77xx series smartphones.
Comparison of leading operating systems
OS Symbian is widely used in budget devices. The system has become the hallmark of the Nokia brand. The Belle and Anna updates breathed new life into the Japanese company's lineup. Nevertheless, today new smartphones on this OS are no longer available. According to the characteristics, the system is designed conveniently. If not for the popularity of "Android" and IOS, Symbian products would still be in trend. Nokia smartphones have a colorful multimedia center and a fast engine. Almost all are supported modern applications and interfaces.
Phones on android base today they are leading in terms of popularity throughout the world. This is despite the fact that the OS is quite young. The first version was released into wide production only 6 years ago. Owns the rights to software The system attracts with its colorfulness and efficiency of work. The latest versions of the OS contain many new useful functions and services. Smartphones of such brands as HTC, Samsung, Motorola and others are being released today on the basis of Android.
Apple iOS is the second most popular operating system among mobile platforms. The interface is convenient, clear, functional. Unlike all other manufacturers, Apple focuses not on but on activities. That is why all updates relate to functionality, and not new multimedia chips.
Windows systems for mobile platforms are not as popular as they are for computers. It's all about the awkward interface. It is difficult for inexperienced users to understand the available functionality. Often the most important options are hidden away in the menu. And if Windows 7 still had a colorful user-friendly interface and optimized requirements, then Eight was just a failure. The only thing that saved the new OS was proper marketing.
MOAP and Nokia S90 platforms
These operating systems were released independently from Symbian software products. The MOAR platform was created for devices commissioned by the Japanese telecom operator DoCoMo. On its basis, users for the first time got the opportunity to use the 3G service. Today, phones from Panasonic, Fujitsu, Mitsubishi, etc. work on the basis of MOAR.
The Series 90 platform from Nokia developers was later integrated into Symbian OS version 7. The prototype of the system was S80 OS from Psion. As for the Nokia S90, thanks to it, it became possible to support screens with an extension of up to 640 pixels. It was a big leap forward. The S90's interface is similar in functionality to the Internet Tablet. In 2005 it was decided to introduce platform developments in Symbian S60 for branded Nokia smartphones. The move allowed the company to take off in the global touchscreen phone market.
Symbian S60 platform
This software product remained unattainable for competitors for a long time. As a result, brands such as LG, Lenovo, Samsung, Panasonic and others licensed the platform for their own needs. The OS development was carried out in cooperation with the companies "Electrobit", "Mobica" and others. The operators Orange and Vodafone were additionally engaged in the supply of the product.
Symbian OS S60 is standard smartphone software that supports Python, Java, and C ++. The functionality includes updated libraries for telephony and multimedia, PIM tools. The maximum resolution supported by the platform is 360 by 640 pixels.
The main drawback of the system is a strict certification mechanism, which significantly limits the possibilities of users.
Symbian S80 platform
This product has become a real flagship of Nokia phones. OS Symbian 9.x was developed on its basis. The platform has been put into production since 2000. Specializes in communication communicators. Can support non-standard display formats such as 640 x 200 dots. The functionality has a built-in qwerty keyboard.
For some time, the platform was left without updates. After 2005, she entered the development of a new universal operating system, which was used in the Nokia E90. It's worth noting that the platform interacts with J2ME applications and TLS and SSL interfaces. The system has a full-fledged opera browser and a file manager with integrated e-fax. Recent updates have allowed access to Bluetooth and Wi-Fi.
UIQ platform
It is the most powerful and costly Symbian technology developed. The platform is a quartz crystal focused on improving the graphics component. UIQ provides the operating system kernel with additional components. Due to this, telephone devices become multifunctional and open to any possibilities.
The platform interacts with third party applications and is focused on touch control. The software part is written in C ++. There is support for Java applications. UIQ technology allowed to achieve a display depth of 4096 colors. Newer versions of the platform have expanded this figure to 18 bits. The updated UIQ 3.2 interacts with services such as MMS Postcard and OMA IMPS.
The platform programmatically supports Visual Studio, Eclipse, Java API, Carbide. Improved Wi-Fi integration technology. Built-in widgets, browser, multimedia applications, etc. are available.
Symbian OS devices
Most of the mobile phone models that operate on the Symbian OS are smartphones and other devices from Nokia. More than three dozen such devices are read. These are 5230, 5800 Xpress, C7-00, and simpler models such as Nokia E72, N93 and others.
Also at one time Symbian OS was in demand in Sony Ericsson devices. These are such models as P900, M600, Vivaz, W960, etc. Other brands include Motorola A1000 and Samsung i8910.
If Symbian had not had such famous competitors as Android and IOS, the number of devices supporting its OS would have been much larger.
Symbian games and applications
All major multimedia programs are built into the system. It is a video player, music service, and imaging applications. In Symbian OS, programs occupy an insignificant part of the phone. This was done on purpose to unload internal memory... The standard functionality includes the Opera 9.5 browser and a utility that monitors system updates.
Among the games are the well-known Angry Birds, OpenTTD and Cut the Rope, as well as Adventures of Tintin and Fruit Ninja.
Symbian OS -operating system for cell phones, smartphones and communicators, was developed by the Symbian consortium founded in June 1998 by the companies: Nokia, Psion, Ericsson and Motorola. Later the companies joined the consortium: Sony Ericsson, Siemens, Panasonic, Fujitsu, Samsung, Sony, Sharp and Sanyo. Of course, now this system is dying and there are fewer and fewer devices on it, but it deserves a story about itself, because at one time it was what it is now Android.
The Symbian OS is the successor to the EPOC OS. But in 1998-2000 most of the operating system was rewritten for optimization. program code to run the OS on devices that have a limited amount of resources. The developers of Symbian OS have managed to achieve significant savings in memory, improved caching of program code, which means faster operation of programs under Symbian OS, while taking into account lower power consumption requirements.
Starting with Symbian OS 9.x, a very important protection mechanism has appeared, which allows you to delimit APIs in accordance with the rights of individual applications. The main languages \u200b\u200bfor developing applications for Symbian OS are: C ++, OPML, and there is also support for Java applications.
At the time of 2010, the most common (in terms of the number of devices) version was Symbian OS Series 60 3rd Edition and 5th Edition. Since autumn 2010, only Nokia has been equipping its smartphones with Symbian OS. Prior to that, this OS was also used by such companies as Samsung, Sony Ericsson and some others. At the moment, the production of smartphones with Symbian OS is discontinued and now dominate Android and iOS.
In general, Symbian and Nokia came to naught together, also thanks to the beloved Microsoft company. The Nokia company itself did not go anywhere, it simply sold to Microsoft a part of the company that was engaged in mobile devices, and itself continues to operate and has two key divisions: Nokia Networks - supplier of telecommunications equipment and Nokia Technologies - is engaged in the development of advanced technologies and licensing of the Nokia brand to third parties.
On the network you can find more firmware modified by enthusiasts for various models of phones / smartphones on Symbian. For example, I reflashed my old Nokia 5230 and the new firmware surprised me with its great functionality, I would even say that I got closer to Android, not entirely of course, but better than it was initially. So look for the firmware for your phone / smartphone, Yandex will help you.
And if Nokia were more agile, who knows, maybe Symbian OS would have remained the dominant operating system on mobile devices and Android would not have conquered the market so easily. And Nokia and not Apple and Samsung would remain the flagship on the market. But history does not know the subjunctive moods and it happened as it happened.
If you are interested in a more detailed story, then watch a video from Dmitry Bachilo about Nokia and Simbian. He told more and more in detail and I see no reason to repeat myself.
