When we talk about smartphones, two giants immediately appear in our heads: Android and iOS. These two platforms have captured more than 99% of the global market, creating the illusion that there are simply no other options. However, the digital world is much wider, and outside the duopoly of Google and Apple there are interesting and sometimes unique solutions hidden.
Understanding what other operating systems there are is important not only for techno-enthusiasts, but also for ordinary users looking for an alternative to the total control of corporations or specific tasks. For example, in the segment of smart watches or budget push-button phones, completely different players dominate.
In this article we will analyze the landscape of mobile OS, evaluate their real market share and find out why some of them, despite their technological superiority, have not become widespread. You will learn about HarmonyOSwhich challenges Western giants, and about niche systems that preserve data privacy.
The hegemony of two giants: Android and iOS
Today, the mobile device market is unevenly divided. Android occupies a leading position due to its openness and a huge variety of devices - from state-owned ones costing 5 thousand rubles to flagships costing 150 thousand. The flexibility of this system allows manufacturers like Samsung, Xiaomi i Google to experiment with interfaces and functions.
On the other hand is iOS from Apple. This is a closed ecosystem where hardware and software are created by one company. This approach provides unprecedented optimization and long-term device support, but limits the possibility of customization. The user receives a stable product, but must play by Apple's rules.
Why can't other systems break through? The main reason is the lack of applications. Developers create software primarily for two main platforms, since the entire audience is concentrated there. Launching a new OS requires enormous investments in attracting content creators, which only a few can do.
⚠️ Attention: When choosing a smartphone on a rare operating system, make sure that all the banking applications and instant messengers you need are available there. Often popular services simply do not release versions for alternative platforms.
HarmonyOS: Chinese response to Western sanctions
One of the most ambitious new products in recent years was HarmonyOS from the company Huawei. Initially positioned as a system for the Internet of Things, it quickly evolved into a full-fledged replacement for Android for smartphones after the introduction of US trade restrictions.
The modern version, known as HarmonyOS NEXT, completely abandoned the Linux kernel and support for Android applications (APK). This makes it the third most important mobile OS in the world, with its own architecture and ecosystem. The system is famous for its smooth operation and deep integration with a smart home.
For users in Russia and the CIS, the situation is twofold. On the one hand, Huawei is actively developing local services and partnerships. On the other hand, the lack of familiar Google services and many Western applications creates certain difficulties when migrating from the usual Android.
Technical features of HarmonyOS
The system kernel is microkernel, which theoretically increases security and fault tolerance. Distributed architecture allows devices to pool their resources: for example, use a phone camera for a video call on a tablet or the power of a PC to process photos from a smartphone.
KaiOS: a revolution in the world of push-button phones
If you think that feature phones are a relic of the past, then the system KaiOS will make you change your mind. This platform turns simple devices with a physical keyboard into full-fledged smart gadgets that support 4G, Wi-Fi and even navigation.
KaiOS is based on web application technologies (HTML5), which makes it light and fast even on weak hardware. Brands such as Nokia (HMD Global) and Alcatel actively produce models on this OS. They are ideal for the elderly, children, or as a second phone to relieve digital noise.
Despite the simplified interface, the system supports popular services: YouTube, Google Maps, Twitter and even WhatsApp. This makes it a unique niche product that occupies a significant market share in developing countries, where smartphones can still be too expensive.
- 📱 Supports 4G and GPS in devices costing from 2000 rubles.
- 🔋 Incredible autonomy: up to several weeks of work without recharging.
- 🌐 Access to the KaiStore application store with adapted software.
Niche and private alternatives
For those who value privacy over convenience, there are specialized operating systems. A striking example is /e/OS an Android fork, completely cleared of Google services and trackers. It is aimed at users who want complete control over their data.
Also worth mentioning PureOS i Ubuntu Touch. These are open source projects that try to create an independent mobile environment. However, their installation often requires technical skills, and compatibility with modern software remains low.
These systems are not mass products out of the box. Most often, they need to be installed manually on compatible devices or purchased specialized smartphones, such as PinePhone or Librem 5. This is a choice for geeks and paranoids in the good sense of the word.
If you want to try an alternative OS without buying a new phone, look for information about custom firmware for your current model. However, remember that this may void the warranty.
Comparative table of mobile platforms
To clearly assess the differences between the main market players, let's look at their key characteristics in comparison. This will help you understand which system is suitable for your specific tasks.
| OS | Developer | Kernel type | Application availability |
|---|---|---|---|
| Android | Linux | Huge (Google Play) | |
| iOS | Apple | Unix (XNU) | Huge (App Store) |
| HarmonyOS | Huawei | Microkernel | Growing (AppGallery) |
| KaiOS | KaiOS Technologies | Firefox OS (Gecko) | Limited (KaiStore) |
As can be seen from the table, the variety of architectures is amazing. While Android and iOS use time-tested monolithic kernels, new players are experimenting with microkernels and web technologies to achieve better energy efficiency.
Why Windows Phone and other projects died
The history of mobile technologies knows many examples of high-profile failures. The most famous of them is Windows Phone from Microsoft. Despite the unique tile design (Metro UI) and good performance, the platform was unable to retain developers.
The lack of popular applications was the nail in the coffin. Users went to Instagram, Snapchat and quality games. Microsoft tried to save the situation with emulators of Android applications, but it was too late.
⚠️ Attention: The mobile OS market has a strong network effect. The more users, the more developers, and the more attractive the platform. It is extremely difficult for a new system to break this circle without huge financial investments.
The fate of Windows Phone was shared by other projects, such as Firefox OS, Sailfish OS (in the mass segment) and Bada from Samsung. They either transformed into niche solutions or were completely closed, giving way to two leaders.
The success of a mobile OS does not depend on the quality of the code, but on the size of the application ecosystem and the loyalty of developers.
The future of mobile operating systems
What awaits us in the future? Further convergence likely. The line between smartphone, tablet, laptop and TV is blurring. Systems like HarmonyOS and updated Android seek to become a unified environment for all user devices.
Interest in decentralized systems and blockchain smartphones is also growing, although this trend is still in its infancy. Perhaps the emergence of new form factors, such as foldable devices or AR glasses, will give new platforms a chance to take their place.
For now, users are left to choose between the flexibility of Android and the stability of iOS, occasionally looking at alternatives like KaiOS for specific tasks. The main thing is to understand your needs and not pursue novelty at the expense of functionality.
Is it possible to install Android on an iPhone?
No, it is impossible. The iPhone's hardware architecture and Apple's bootloader are tightly tied to iOS. There are emulator projects, but they work extremely slowly and do not provide a full experience of using Android.
Which OS is the safest?
In terms of virus protection for the average user - iOS, due to the closed ecosystem. For advanced users who know how to customize the system, specialized Linux-based distributions such as GrapheneOS are considered the most secure.
Will phones running KaiOS stop working?
In the near future - no. The platform is actively developing and is supported by major manufacturers of push-button phones. However, the lifespan of such devices is usually shorter than that of flagship smartphones.
Is there Russification for HarmonyOS?
Yes, the system fully supports the Russian language and has localized services for the CIS countries, since Huawei is actively working in these markets.
