WMaemo is a software platform originally developed by Nokia, now developed by the community, for smartphones and Internet tablets. The platform comprises both the Maemo operating system and SDK.
WMeeGo is a discontinued Linux distribution hosted by the Linux Foundation, using source code from the operating systems Moblin and Maemo. Primarily targeted at mobile devices and information appliances in the consumer electronics market, MeeGo was designed to act as an operating system for hardware platforms such as netbooks, entry-level desktops, nettops, tablet computers, mobile computing and communications devices, in-vehicle infotainment devices, SmartTV / ConnectedTV, IPTV-boxes, smart phones, and other embedded systems.
WThe N-Gage service was a mobile gaming platform from Nokia that was available for several Nokia smartphones running on S60 (Symbian). N-Gage provided numerous games with 3D graphics into an application featuring online and social features. It takes its name from the original 2003 N-Gage gaming device, which it succeeded.
WThe Nokia Asha platform is a mobile operating system (OS) and computing platform designed for low-end borderline smartphones, based on software from Smarterphone which was acquired by Nokia. The platform inherits UI similarities mostly from MeeGo "Harmattan", and replaces Series 40 on Nokia's low-end devices. The user interface design team was headed by Peter Skillman, who had worked previously on webOS and the design of MeeGo for the Nokia N9.
WThe Nokia X platform was a Linux-based mobile operating system and software platform originally developed by Nokia, and subsequently by Microsoft Mobile. Introduced on 24 February 2014, it was forked from Android and used on all the devices of the Nokia X family. It was also the next Nokia Linux project after the ill-fated MeeGo.
WThe Series 30, often shortened as S30, is a software platform and application user interface created by Nokia for its entry level mobile phones, lower than Series 40. S30 phones are not capable of running Java apps. In 2014, Microsoft acquired Nokia's mobile phones business and later discontinued S30 in favor of Series 30+.
WSeries 30+ is a software platform and application user interface used for Nokia-branded mobile devices. The platform was introduced by Nokia in September 2013, first appearing on the Nokia 108, and has been the main Nokia feature phone operating system after the end of the Series 30 and Series 40 platforms in 2014. Despite the similar name and user interface, S30+ is technically completely different and unrelated to S30.
WThe S60 Platform is a software platform for smartphones that runs on top of the Symbian operating system. It was created by Nokia based on the 'Pearl' user interface from Symbian Ltd. It was introduced at COMDEX in November 2001 and first shipped with the Nokia 7650 smartphone. The platform has since seen 5 updated editions. Series 60 was renamed to S60 in November 2005.
WSymbian is a discontinued mobile operating system (OS) and computing platform designed for smartphones. Symbian was originally developed as a proprietary software OS for PDAs in 1998 by the Symbian Ltd. consortium. Symbian OS is a descendant of Psion's EPOC, and was released exclusively on ARM processors, although an unreleased x86 port existed. Symbian was used by many major mobile phone brands, like Samsung, Motorola, Sony Ericsson, and above all by Nokia. It was also prevalent in Japan by brands including Fujitsu, Sharp and Mitsubishi. As a pioneer that established the smartphone industry, it was the most popular smartphone OS on a worldwide average until the end of 2010—at a time when smartphones were in limited use—when it was overtaken by iOS and Android. It was notably not as popular in North America.
