Symbian

Symbian is a discontinued mobile operating system (OS) and computing platform designed for smartphones. It was originally developed as a proprietary software OS for personal digital assistants 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.

Tizen

Tizen (ˈtaɪzɛn) is a Linux-based mobile operating system backed by the Linux Foundation, developed and used primarily by Samsung Electronics. The project was originally conceived as an HTML5-based platform for mobile devices to succeed MeeGo. Samsung merged its previous Linux-based OS effort, Bada, into Tizen, and has since used it primarily on platforms such as wearable devices and smart TVs. Much of Tizen is open source software, although the software development kit contains proprietary components owned by Samsung, and portions of the OS are licensed under the Flora License, a derivative of the Apache License 2.

TouchWiz

TouchWiz is a discontinued user interface developed by Samsung Electronics with partners, featuring a full touch user interface. It is sometimes incorrectly referred to as an operating system. TouchWiz was used internally by Samsung for smartphones, feature phones and tablet computers, and was not available for licensing by external parties. The Android version of TouchWiz also comes with the Samsung-made app store Samsung Galaxy Store. It was replaced by Samsung Experience in 2017 with the release of Android 7.

Comparison of mobile operating systems

This is a comparison on mobile operating systems. Only the latest versions are shown in the table below, even though older versions may still be marketed.

Samsung Electronics

Samsung Electronics Co., Ltd. (, sometimes shortened to SEC and stylized as SΛMSUNG) is a South Korean multinational major appliance and consumer electronics corporation headquartered in Yeongtong-gu, Suwon, South Korea. It is currently the pinnacle of the Samsung chaebol, accounting for 70% of the group's revenue in 2012. However, Lee Jae-yong has stated his intentions on making sure his children would not inherit significant Samsung Electronics positions, which would significantly change the chaebol's inner workings.

Mobile operating system

A mobile operating system is an operating system for smartphones, tablets, smartwatches, smartglasses, or other non-laptop personal mobile computing devices. While computers such as typical/mobile laptops are "mobile", the operating systems used on them are generally not considered mobile ones, as they were originally designed for desktop computers that historically did not have or need specific mobile features. This line distinguishing mobile and other forms has become blurred in recent years, due to the fact that newer devices have become smaller and more mobile unlike hardware of the past.
