How to Understand and Evaluate Huawei's HarmonyOS: A Step-by-Step Guide to Its Rise and Impact

Introduction

In recent years, Huawei has emerged as China's strongest challenger to Apple's dominance in consumer technology. With a full lineup of smartphones, laptops, and tablets, the company now rivals the best in the world. This shift is fueled by a rapid adoption of domestic software, including operating systems and databases, driven by improved smoothness and ease of use. At the heart of this transformation is HarmonyOS, an open-source operating system that, as of end of March 2026, powers over 55 million devices—adding 23 million in just six months. This guide will walk you through the key factors behind HarmonyOS's growth, its features, open-source implications, and market impact. By the end, you'll have a clear understanding of what HarmonyOS means for consumers, developers, and the tech industry.

What You Need

Basic knowledge of mobile operating systems (Android, iOS)
Familiarity with open-source concepts (optional but helpful)
A willingness to explore technical and business perspectives
Access to a device running HarmonyOS (optional for hands-on experience)

Step-by-Step Guide

Step 1: Grasp the Scale of HarmonyOS Adoption

Begin by understanding the sheer momentum. HarmonyOS now runs on 55 million devices, a milestone reported by Huawei Executive Director Yu Chengdong. This includes smartphones, tablets, and other gadgets. Compare this to six months prior when the count was 32 million—a massive jump of 72%. This rapid growth signals serious traction, especially within China where domestic software usage is surging. The numbers suggest HarmonyOS is no longer a niche experiment but a viable alternative to iOS and Android.

Key takeaway: The 55 million figure isn't just a statistic; it represents a shift in consumer preference and market dynamics.

Step 2: Examine the Core Features of HarmonyOS 6

To understand why users are flocking to HarmonyOS, explore its latest release, HarmonyOS 6. The operating system introduces several standout improvements:

Fluid animations: Lighting and glass-like UI elements make the phone feel smoother and more responsive.
Performance boost via Ark engine: The Ark engine handles multimedia and graphics APIs, significantly improving gaming, video playback, and overall battery life.
AI-assisted tools: These include smart scheduling and camera features that adjust depth and focus with a single touch, enhancing user convenience.
AI-driven StarShield Security: An anti-scam and privacy-focused architecture that uses artificial intelligence to protect users.
Wider native app support: Third-party developers are increasingly offering native adaptations, expanding the ecosystem.
Affordable device range: Huawei's growing lineup of cost-effective yet feature-rich devices makes HarmonyOS accessible to more people.

These features together create a compelling user experience that rivals established players.

Step 3: Understand the Open-Source Foundation

HarmonyOS is built on OpenHarmony, an open-source mobile operating system base similar to Android's AOSP but independent. This foundation allows for community contributions and encourages growth in related projects, such as EulerOS. However, a catch remains: many proprietary layers—the Ark compiler, UI elements—are closed-source, and documentation is largely in Chinese, limiting global accessibility. This hybrid model means while HarmonyOS benefits from open-source collaboration, it retains significant control within Huawei.

Action: Visit the OpenHarmony project website to see its codebase and community activity. Note how contributions are shaping the kernel.

Step 4: Assess the Impact on the FOSS Community

The mass adoption of HarmonyOS has mixed effects on free and open-source software (FOSS) communities. On one hand, it drives more contributions to OpenHarmony, strengthening the ecosystem. On the other hand, Huawei's aggressive promotion—some say spamming—of its OS to open-source projects has drawn criticism. Some view this as intrusive, while others see it as a necessary push to expand app support. Weigh these perspectives:

Positive: Increased developer interest and funding for OpenHarmony.
Negative: Potential dilution of community autonomy and reliance on a single corporation.

Consider how this balance affects your own view of open-source collaboration.

Step 5: Evaluate HarmonyOS as a Market Competitor

Finally, consider what HarmonyOS means for the duopoly of Apple and Google. A new challenger, especially one offering affordable devices, keeps all players on their toes. For consumers, this means more choices, better prices, and faster innovation. The 55 million device milestone proves that there is room beyond iOS and Android, at least in China. But global expansion remains a hurdle due to US restrictions and the closed-source components.

Bottom line: HarmonyOS is a serious contender that could reshape the mobile OS landscape over the next few years.

Tips for a Deeper Understanding

Stay updated: Follow Huawei's developer conferences and OpenHarmony releases to track changes in the ecosystem.
Try it yourself: If possible, use a device with HarmonyOS (e.g., Huawei Mate 60 series) to experience the fluid animations and AI features firsthand.
Join the community: Participate in OpenHarmony forums or local meetups to understand developer sentiments.
Watch for policy shifts: US export controls may affect Huawei's ability to expand globally—monitor trade news.
Compare with alternatives: Use a side-by-side test of HarmonyOS, Android, and iOS for app performance, security, and ease of use.
Analyze app ecosystem growth: Track the number and quality of native apps over time to gauge platform maturity.

By systematically following these steps and tips, you'll gain a comprehensive understanding of HarmonyOS's rise and its potential to challenge the status quo.
