Huawei Developing Its Own OS? The Full Story

Updated 4 November 2026 · Standard formula, shown below

Yes, Huawei has been developing its own operating system, HarmonyOS, since at least 2016, with the first commercial version released in 2019. It was created as a strategic response to US trade restrictions that cut off Huawei’s access to Google’s Android services, and it now powers everything from smartphones to smart TVs. This article explains what HarmonyOS actually is, how it differs from Android, what it means for users, and the current state of the project in 2024.

Why Huawei Built Its Own OS

In May 2019, the US Department of Commerce placed Huawei on the Entity List, which barred American companiesâ€”including Googleâ€”from supplying software, hardware, and services to the Chinese tech giant. Overnight, new Huawei phones could no longer ship with Google Mobile Services (GMS), meaning no Google Play Store, no Gmail, no Google Maps, and no automatic Android updates. Existing phones kept working, but the future of Huawei’s smartphone business was in doubt.

Huawei had actually started work on an in-house OS years earlier as a contingency plan. The trade ban accelerated that project dramatically. In August 2019, at its annual developer conference, Huawei unveiled HarmonyOS (Hongmeng OS in China) as a lightweight, IoT-focused operating system. The first version ran only on smart displays and other connected devices. It wasn’t until 2021 that HarmonyOS 2.0 arrived on smartphones, replacing Android on new Huawei phones sold in China.

What HarmonyOS Actually Is

HarmonyOS is not a fork of Android in the way that, say, OxygenOS or MIUI are. It’s a fundamentally different architecture. Android is built around a Linux kernel and a Java-based runtime. HarmonyOS uses a microkernel design, which means the core operating system functions are kept minimal and separate from the rest of the system. This makes it more modular and allows it to be deployed across a huge range of devicesâ€”from a smartwatch with 128KB of RAM to a 4K TV.

The key feature is “distributed capability.” A HarmonyOS phone can seamlessly hand off a video call to a HarmonyOS tablet, or use a HarmonyOS speaker’s microphone for a voice command. Devices running HarmonyOS can share hardware resources with each other over a local network, creating a unified experience across a user’s entire ecosystem. This is similar in concept to Apple’s Continuity, but Huawei positions it as more open and cross-vendor.

HarmonyOS vs. Android: The Real Differences

Kernel: Android uses a monolithic Linux kernel; HarmonyOS uses a microkernel, which is smaller, more secure, and more efficient for resource-constrained devices.
App compatibility: HarmonyOS smartphones can run Android APK files, but they do so through a compatibility layer, not natively. This is a bridge, not a foundation.
App ecosystem: Android has millions of apps on Google Play; HarmonyOS has its own AppGallery with a few hundred thousand apps, mostly localized for China.
Updates: Android updates depend on Google and the phone maker; HarmonyOS updates are controlled entirely by Huawei, so they can be pushed faster and for longer.
Open source: Android is open source (AOSP); HarmonyOS has an open-source version called OpenHarmony, but Huawei’s commercial version includes proprietary components.

In practice, for most users, the biggest difference is the app store. If you can find all the apps you need on Huawei’s AppGallery, HarmonyOS works fine. If you rely on Google apps or niche third-party apps, you’ll struggle.

How to Get HarmonyOS on Your Phone

If you already own a Huawei phone, the path to HarmonyOS depends on where you live and what model you have.

Check your region: In China, most recent Huawei phones have already been upgraded to HarmonyOS 4.0. In Europe and other global markets, Huawei has been slower to roll it out, and some models still ship with Android (without Google services).
Check your model: Huawei’s official upgrade list includes most models from the P40, Mate 30, and newer. Older models like the P30 series have received the update in some regions but not others.
Back up your data: The upgrade process wipes the device. Use Huawei’s built-in backup tool or a third-party app to save your photos, contacts, and files.
Download the update: Go to Settings > System & Updates > Software Update. If the HarmonyOS update is available for your device, it will appear there. You can also use the Huawei HiCare app or the official website to check eligibility.
Install and restart: The installation takes about 20-30 minutes. Your phone will restart several times. After it’s done, you’ll be on HarmonyOS.

If your phone is not on the official list, there are unofficial methods involving flashing firmware, but those are risky and can brick your device. It’s not recommended unless you’re an experienced user.

Common Problems and Misconceptions

“HarmonyOS is just Android with a new name.” This is the most common misconception. While HarmonyOS can run Android apps, its kernel and core architecture are different. It’s more accurate to say it’s a new OS with an Android compatibility layer. That said, the user interface and many system apps look and feel very similar to EMUI, Huawei’s old Android skin, so the transition feels seamless.

“I can’t install Google apps on HarmonyOS.” Correct. Google Mobile Services are not available on HarmonyOS. There are workarounds involving APK sideloading and microG, but they are unreliable and often break after updates. If you need Google apps, HarmonyOS is not for you.

“HarmonyOS is only for phones.” No. HarmonyOS is designed for a wide range of devices. In fact, the first devices to run it were smart displays, not phones. Today, it runs on tablets, smartwatches, TVs, speakers, routers, and even cars.

“My Huawei phone will stop working if I don’t upgrade.” No. Your phone will continue to work on Android if you don’t upgrade. However, you won’t receive security patches or new features, and over time, apps may stop supporting the older Android version.

Costs and Availability

HarmonyOS itself is free for users. Huawei does not charge for the operating system or the upgrade. The cost is in the ecosystem: you may need to buy new Huawei devices to take full advantage of the distributed features, and you may need to purchase apps or subscriptions from the AppGallery that you previously got from Google Play.

Huawei has also made HarmonyOS available to other manufacturers. The open-source OpenHarmony project allows third-party companies to build their own devices on the OS. As of 2024, several Chinese companies have released smart home products and even some low-end phones running OpenHarmony, but adoption outside China remains minimal.

Safety and Security

Huawei has faced repeated security concerns from Western governments, who worry that the company’s ties to the Chinese government could lead to espionage. Huawei denies these allegations, and no public evidence has shown backdoors in HarmonyOS. However, the lack of independent security audits and the Chinese government’s legal ability to compel data access mean that security-conscious users in the West should be cautious.

From a technical standpoint, HarmonyOS has some security advantages. The microkernel design reduces the attack surface, and the distributed architecture allows for fine-grained permission controls. But it also means that security depends on Huawei’s proprietary code, which is not fully open to public scrutiny.

Alternatives to HarmonyOS

If you’re considering a Huawei phone but are worried about HarmonyOS, there are alternatives:

Android with Google services: Samsung, Xiaomi, OnePlus, and most other brands offer the full Google experience. This is the safest choice if you rely on Google apps.
Android without Google services: Some phones, like those from Honor (formerly a Huawei sub-brand), ship with Android but no Google apps. You can sideload apps, but it’s a hassle.
iOS: If you value long-term updates and a strong app ecosystem, an iPhone is the main alternative to HarmonyOS’s ecosystem approach.
Other microkernel OSes: Fuchsia, developed by Google, is similar in concept to HarmonyOS but is not yet available on consumer devices.

Frequently Asked Questions

Will HarmonyOS work with my existing Android apps? Yes, most Android apps will run on HarmonyOS through its compatibility layer. However, apps that rely heavily on Google services (like Google Maps or YouTube) will not work properly, and some apps may have bugs or performance issues.

Can I install Google Play Store on HarmonyOS? No, not officially. There are unofficial methods using APK files and microG, but they are unreliable, may violate terms of service, and can break after system updates. It’s not recommended for everyday use.

Is HarmonyOS available outside China? Yes, but the rollout has been slower and more limited. Huawei has released HarmonyOS 4.0 on some global models, but many international users still have Android. Check Huawei’s official website for your specific model.

How long will Huawei support HarmonyOS with updates? Huawei has committed to providing at least four years of major OS updates and five years of security patches for its flagship phones. This is comparable to Samsung and Google’s update policies.

Can I downgrade back to Android after upgrading to HarmonyOS? In some cases, yes, but it’s not officially supported. Downgrading requires flashing the original Android firmware, which wipes your data and may void your warranty. It’s a complex process and not recommended unless you’re an advanced user.

Is HarmonyOS really independent from Android? The core architecture is independent, but the app compatibility layer and some user interface elements are derived from Android. Huawei claims HarmonyOS is fully independent, but critics note that it still relies on Android’s open-source code for app compatibility.
