S60 Platform

The S60 Platform, originally named Series 60 User Interface, is a discontinued software platform and graphical user interface for smartphones that runs on top of the Symbian operating system. It was created by Nokia based on the 'Pearl' interface from Symbian Ltd. S60 was introduced at COMDEX in November 2001 and first shipped with the Nokia 7650 smartphone; the original version was followed by three other major releases.

In 2008 after Nokia bought out Symbian Ltd., the Symbian Foundation was formed to consolidate all the assets of different Symbian platforms (S60, UIQ, MOAP), making it open source. In 2009, based on the code base of S60, the first iteration of the platform since the creation of Symbian Foundation was launched as S60 5th Edition, or Symbian^1, on top of Symbian OS 9.4 as its base. Subsequent iterations dropped the S60 brand and were named solely under the Symbian name.

Overview

The S60 middleware was a multivendor standard for smartphones that supports application development in Java MIDP, C++, Python and Adobe Flash. Its API was called Avkon UI. S60 consists of a suite of libraries and standard applications, such as telephony, personal information manager (PIM) tools, and Helix-based multimedia players. It was intended to power fully featured modern phones with large colour screens, which are commonly known as smartphones.

Originally, the most distinguishing feature of S60 phones was that they allowed users to install new applications after purchase. Unlike a standard desktop platform, however, the built-in apps are rarely upgraded by the vendor beyond bug fixes. New features are only added to phones while they are being developed rather than after public release. Certain buttons are standardized, such as a menu key, a four way joystick or d-pad, left and right soft keys and a clear key.

S60 was mainly used by Nokia but they also licensed it to a few other manufacturers, including Lenovo, LG Electronics, Panasonic, Samsung, Sendo, Siemens Mobile, Sony Ericsson, Solstice and Vertu. Sony Ericsson notably was the main vendor using the competing UIQ Symbian interface.

In addition to the manufacturers the community includes:
* Software integration companies such as Sasken, Elektrobit, Teleca, Digia, Mobica, Atelier.tm
* Semiconductor companies Texas Instruments, STMicroelectronics, Broadcom, Sony, Freescale Semiconductor, Samsung Electronics
* Operators such as Vodafone and Orange who develop and provide S60-based mobile applications and services
* Software developers and independent software vendors (ISVs).

S60 editions

There have been four major releases of S60: Series 60 (2001), Series 60 Second Edition (2002), S60 3rd Edition (2005) and S60 5th Edition (2008). Each release had an updated version called ''Feature Pack'', sometimes known as ''relay''. Each runs on top of a different Symbian OS version.

;Series 60 1st Edition: The devices' display resolution was fixed to 176×208. The Siemens SX1 meanwhile had 176×220.

*Version 0.9 was the original and first shipped with Nokia 7650.
*Version 1.2 (marketed as Feature Pack 1) first shipped with Nokia 3600/3650 in 2003.

;Series 60 2nd Edition: Also known as S60v2.
*Version 2 was the original and first shipped with Nokia 6600.
*Version 2.1 (Feature Pack 1) first came with Nokia 6620.
*Version 2.6 (Feature Pack 2) first came with Nokia 6630.
*Version 2.8 (Feature Pack 3) first started shipping with Nokia N70 in September 2005. FP3 now supports multiple resolutions, i.e. Basic (176×208), and Double (352×416). The N90 was the first Series 60 device to support a higher resolution (352×416).

;S60 3rd Edition: S60v3 uses a hardened version of Symbian OS (v9.1), which has mandatory code signing. In S60v3, a user may install only programs that have a certificate from a registered developer, unless the user disables that feature or modify the phone's firmware through third-party hacks that circumvent the mandatory signing restrictions. This makes software written for S60 1st Edition or 2nd Edition not binary-compatible with S60v3.
*Version 3 was first introduced with Nokia N91 in 2006.
*Version 3.1 (Feature Pack 1) first shipped with Nokia N95.
*Version 3.2 (Feature Pack 2) first shipped with Nokia N78.

:In 2006, a "Designed for S60 Devices" logo program for developers was launched. The logotype can be used with conforming programs regardless of them being native Symbian or Java.

;S60 5th Edition / Symbian^1: In October 2008 Symbian^1, also known as S60v5, was launched as the first OS under the Symbian Foundation, based on the S60 code so therefore also called S60 5th Edition. Nokia skipped the number 4 as they traditionally always do (due to East Asian tetraphobia). S60 5th Edition runs on Symbian OS version 9.4. The major feature of 5th Edition is support for high-resolution 640×360 touchscreens; before 5th Edition, all S60 devices had a button-based user interface. S60 5th Edition also integrates standard C/ C++ APIs and includes Adobe Flash Lite 3.0 with S60-specific ActionScript extensions that give Flash Lite developers access to phone features like contacts, text messaging, sensors and device location information ( GPS). : Despite the introduction of S60 5th Edition, the 3rd Edition continued to be marketed new as well, as 5th Edition is specially designed for, and exclusively available on touchscreens (e.g. Nokia C6-00, Sony Ericsson Satio).

*Version 5 was first introduced with Nokia 5800 XpressMusic in 2008.

:S60 5th Edition was the last edition of S60. It was succeeded by Symbian^2 (based on MOAP) and Symbian^3 in 2010.

Unification of Symbian interfaces

As an OS, Symbian OS originally provided no user interface (UI), the visual layer that runs atop an operating system: this was implemented separately. Other than S60, other examples of Symbian UIs were MOAP; Series 80; Series 90 and UIQ. This separation of UI from underlying OS created both flexibility and some confusion in the market place. The Nokia outright purchase of Symbian in June 2008 was brokered with the involvement of the other UI developers and all major user interface layers had been (or pledged to) donating to the open source foundation, Symbian Foundation, who would independently own the Symbian operating system. It announced its intent to unify different Symbian UIs into a single UI based on the S60 platform.

S60 5th Edition was the first version under the unified Symbian interface, and it was therefore also named Symbian^1. After this, the S60 name was dropped entirely with the release of Symbian^3 in 2010. In November 2010, Nokia abruptly announced that the Symbian Foundation will close down, leaving further Symbian development in question. The company had previously stated that MeeGo would become its smartphone future. In February 2011, Nokia instead announced a partnership with Microsoft to adopt Windows Phone 7 as Nokia's primary operating system, while promising continued support for Symbian and its newer devices until at least 2016. On 29 April 2011, Nokia announced that it would transfer Symbian activities to Accenture along with 3,000 employees.

Symbian^3

Symbian^3 was announced together with Nokia N8 on 27 April 2010. The software is faster than the previous S60 5th Edition and takes better advantage of hardware capabilities to create a snappier performance. Interface wise it is not drastically different although it does have multiple home screens. The task switcher has been revamped and now show thumbnails of each open app. Web browsing experience is also improved with the addition of pinch-to-zoom. The native text messaging app now features a "conversation" interface. While the virtual keyboard is still T9, a QWERTY is offered in landscape view.

Symbian Anna

On 12 April 2011, Nokia announced Symbian Anna as a software update to the Symbian^3 release. Three new devices (500, X7 and E6) were announced which will have Symbian Anna pre-installed. The most significant changes were:
* Portrait QWERTY with split-view data entry
* New Icon Set
* New web browser with an improved user interface, search-integrated address field, faster navigation and page loading.
* Updated Ovi Maps (search public transport, download full country maps via WLAN or Nokia Ovi Suite, check-in to Facebook, Twitter and Foursquare).
* Java Runtime 2.2, Qt Mobility 1.1 and Qt4.7.

Symbian Belle

On 24 August 2011, Nokia announced Symbian Belle (later renamed Nokia Belle) as a software update to the Symbian Anna release. Three new devices (603, 700 and 701) were announced with Belle pre-installed. The most significant changes were:
* Free-form, differently-sized, live widgets
* More homescreens
* Improved status bar
* Dropdown menu
* Modernised navigation
* New apps
* Informative lock screen
* NFC devices
* Visual multitasking

Symbian Carla and Donna

In November 2011, Nokia announced the Carla and Donna updates. Carla was expected to be released in late 2012 or early 2013 and feature a new web browser, new widgets, new NFC capabilities and Dolby Surround audio enhancement. Donna was going to be a dual-core processor exclusive, and was planned to be released late 2013 or early 2014. However, in May 2012 a Nokia executive claimed that Carla and Donna were cancelled, and that Nokia would instead only release Belle Feature Pack 2 later in 2012, lacking many of the new features that were planned for Carla and Donna.

Version history and supported devices
