Tizen OS: Samsung's Open Source Powerhouse for Smart Devices

Tizen is a Linux-based, open-source operating system developed primarily by Samsung Electronics in partnership with the Linux Foundation. Since its debut in 2012, Tizen has served as the backbone of numerous Samsung devices—from smart TVs and wearables to in-car infotainment systems and IoT appliances. This article explores the roots, architecture, applications, and future of Tizen, highlighting its pivotal role in Samsung's broader tech ecosystem.

Origins and Evolution

From Moblin to Tizen

The story of Tizen begins with Intel's Moblin project and Nokia's Maemo. These merged to form MeeGo, which was eventually phased out when Nokia aligned with Microsoft. The Linux Foundation then launched Tizen in 2011, with Intel and Samsung as key contributors.

Initial Releases and Milestones

Tizen 1.0 "Larkspur" launched in 2012. By 2013, Samsung merged its Bada OS into Tizen, simplifying its OS strategy. Key hardware milestones include the Japan-only Systena tablet (2013) and the Gear 2 smartwatch (2014).

Core Technologies

Linux Kernel and System Components

Tizen is based on a monolithic Linux kernel, utilizes the RPM package manager, and incorporates security features like SMACK (Simplified Mandatory Access Control Kernel).

UI and Development Frameworks

Tizen supports both native applications written in C/C++ and web apps using HTML5/JavaScript. It uses EFL (Enlightenment Foundation Libraries) for its UI and Tizen Studio as its official development IDE.

Licensing and Open Source Governance

Licensed under a combination of GPLv2, LGPL, BSD, and Apache 2.0, Tizen balances open development with proprietary control by Samsung, particularly in user-facing applications.

Deployment Across Devices

Smartphones and Tablets

Tizen smartphones like the Z1, Z3, and Z4 targeted emerging markets such as India and Russia. Despite limited commercial success and the closure of the Tizen app store in 2021, they proved the OS's mobile viability.

Smartwatches and Wearables

Between 2014 and 2021, Samsung’s smartwatches—including the Gear and Galaxy Watch series—ran Tizen. Known for efficient performance and bezel-based navigation, Tizen was eventually replaced by Wear OS 3 in newer models.

Smart TVs

Today, Tizen dominates Samsung’s Smart TV lineup, offering an intuitive interface, multi-tasking, streaming app support, and integration with services like Samsung TV Plus. As of 2018, Tizen held a 21% share of the global smart TV OS market.

Automotive Applications

Tizen serves as a reference OS for in-car infotainment through the Automotive Grade Linux initiative. Devices like the Samsung Connect Auto OBD-II dongle showcase its ability to manage connectivity and diagnostics in vehicles.

IoT and Smart Appliances

TizenRT, a real-time OS derived from NuttX, powers resource-constrained devices like refrigerators, washing machines, and other appliances. It integrates seamlessly with Samsung SmartThings for smart home automation.

Development Tools and Community

Tizen Studio

The official Tizen Studio IDE supports app development, debugging, and emulation. It replaced the older SDK and supports both native and web-based app projects.

Community and Ecosystem

The Tizen Association, composed of telecom companies and manufacturers, governs the platform's open development. However, Samsung continues to drive most strategic decisions.

Recent Updates and Future Outlook

Tizen 9.0 M2 and Beyond

Released in October 2024, Tizen 9.0 M2 brought performance improvements and enhanced support for AI-driven devices. Samsung also committed to offering seven years of updates for its AI Smart TVs, reinforcing Tizen’s ongoing relevance.

Strategic Shifts

While Tizen has exited the smartphone and wearable arenas, its core strength lies in consumer electronics and IoT. Samsung’s vertical integration ensures Tizen remains central to its product ecosystem.

Conclusion

Tizen's trajectory—from a Linux experiment to a cornerstone OS in Samsung's portfolio—demonstrates its flexibility and innovation. Though its mobile ambitions have tapered, Tizen thrives in smart TVs, IoT devices, and automotive applications. Backed by open-source principles and Samsung’s infrastructure, Tizen is well-positioned to evolve with the future of connected technology.
