Series 40
Series 40, often shortened as S40, is a software platform and application user interface (UI) software on Nokia's broad range of mid-tier feature phones, as well as on some of the Vertu line of luxury phones. It was one of the world's most widely used mobile phone platforms and found in hundreds of millions of devices. Nokia announced on 25 January 2012 that the company has sold over 1.5 billion Series 40 devices. It was not used for smartphones, with Nokia turning first to Symbian, then in 2012–2017 to Windows Phone, and most recently Android. However, in 2012 and 2013, several Series 40 phones from the Asha line, such as the 308, 309 and 311, were advertised as "smartphones" although they do not actually support smartphone features like multitasking or a fully fledged HTML browser.

In 2014, Microsoft acquired Nokia's mobile phones business. As part of a licensing agreement with the company, Microsoft Mobile is allowed to use the Nokia brand on feature phones, such as the Series 40 range. However, a July 2014 company memo revealed that Microsoft would end future production of Series 40 devices. It was replaced by Series 30+.

History
Series 40 was introduced in 1999 with the release of the Nokia 7110. It had a 96 × 65 pixel monochrome display and was the first phone to come with a WAP browser. Over the years, the S40 UI evolved from a low-resolution UI to a high-resolution color UI with an enhanced graphical look. The third generation of Series 40 that became available in 2005 introduced support for devices with resolutions as high as QVGA (240×320). It is possible to customize the look and feel of the UI via comprehensive themes. In 2012, Nokia Asha mobile phones 200/201, 210, 302, 303, 305, 306, 308, 310 and 311 were released and all used Series 40. The final feature phone running Series 40 was the Nokia 515 from 2013, running the 6th Edition.

Technical information

Applications

Series 40 provides communication applications such as telephone, Internet telephony (VoIP), messaging, email client with POP3 and IMAP4 capabilities and web browser; media applications such as camera, video recorder, music/video player and FM radio; and phonebook and other personal information management (PIM) applications such as calendar and tasks. Basic file management, like in Series 60, is provided in the Applications and Gallery folders and subfolders. Gallery is also the default location for files transferred over Bluetooth to be placed. User-installed applications on Series 40 are generally mobile Java applications. Flash Lite applications are also supported, but mostly used for screensavers.

Web browser
The integrated web browser can access most web content through the service provider's XHTML/HTML gateway. The latest version of Series 40, called Series 40 6th Edition, introduced a new browser based on the WebKit open source components WebCore and JavaScriptCore. The new browser delivers support for HTML 4.01, CSS2, JavaScript 1.5, and Ajax. Also, like the higher-end Series 60, Series 40 can run the UC Browser web browser to enhance the user's web browsing experience. The latest feature phones from the Asha lineup come with the Nokia Xpress Browser which uses proxy servers to compress and optimize web pages in a similar fashion as Opera Mini.

Synchronization
Support for SyncML synchronization of the address book, calendar and notes with external services is present. However, with many S40 phones, these synchronization settings must be sent via an OTA text message.

Software platform
Series 40 is an embedded software platform that is open for software development via standard or de facto content and application development technologies. It supports Java MIDlets, i.e. Java MIDP and CLDC technology, which provide location, communication, messaging, media, and graphics capabilities. S40 also supports Flash Lite applications.
