What is the name of the shell Xiaomi: the evolution of the interface

In the world of modern mobile technology, the Xiaomi brand is at the forefront of offering users powerful hardware at an affordable price. However, hardware is only half the success, because it is the software part that determines the comfort of daily interaction with a gadget. Many newcomers, taking in their hands for the first time a smartphone from this manufacturer, wonder: what is the name of the Xiaomi shell and how it differs from standard Android? The answer to this question is not as clear as it may seem at first glance, since the company recently went through a large-scale rebranding of its ecosystem.

For a long time, the main answer to the question of “what is the shell Xiaomi” was the word MIUI. This acronym has become synonymous with functionality and deep customization, which so loved by millions of fans around the world. However, in late 2023 and early 2026, the situation changed dramatically: the company began the global introduction of a new operating system called HyperOS. This transition marks a new era in the development of interface aimed at connecting smartphones, tablets, cars and smart home devices into a single network.

Understanding the differences between the old and the new systems is essential for every Xiaomi owner to make the most of their device. In this article, we will examine in detail the history of the interface, key features of MIUI and innovations of HyperOS, and answer the questions that users often have when switching or choosing a device.

Historical Excursion: From MIUI V1 to the Present

The company's shell story began long before the company's first self-branded smartphone, the first version of the MIUI V1, launched on August 16, 2010, and was based on Android 2.2, a revolutionary product that offered weekly updates and active engagement with the development community, and it was then that the company's philosophy of listening to users and quickly implementing change was formed.

Over the years, the interface has become more powerful, heavier and more visually overloaded, but at the same time acquired unique features that were absent in “pure” Android. There were themes, second spaces, advanced notification settings and many other tools for the tweaker. The key feature of MIUI has always been the ability to change almost any interface element without obtaining superuser rights (root).

Reaching the pinnacle of development came with the release of MIUI 12 and MIUI 13, which brought new design, improved animation and increased attention to privacy. However, by this point it became clear that the system architecture needed a fundamental overhaul to support the growing ecosystem of IoT devices, which led to the creation of HyperOS, which was the logical continuation and replacement of the legendary shell.

⚠️ Note: When updating from older versions MIUI (Up to date builds may require a complete data reset, as the architecture of file systems and Android partitions has changed significantly over the years.

The evolution of the interface is not just about changing icons, but constantly working on code optimization. While early versions may have been unstable, modern builds are a well-functioning mechanism, although they have their own peculiarities with background processes.

What is MIUI: Architecture and Key Features

MIUI (Mi User Interface) is a proprietary shell developed by Xiaomi for its Android devices. Unlike many competitors who only change the look, Xiaomi developers re-wrote a significant portion of system applications and frameworks, allowing them to implement features that became the standard in Android only a few years later.

The MIUI Theme Store allows you to completely change the visual style of the smartphone: from icons and fonts to the lock screen and system sounds. The user can download the finished design or create his own using the built-in editor.

• 🎨 Deep Customization: the ability to change the behavior of curtains, navigation buttons and gestures.
• 🔒 Second Space: Creating an Isolated Environment in a Smartphone with a Separate Set of Apps and Passwords.
• 📱 Double apps: built-in ability to clone messenger accounts and social networks without third-party software.

An important part of MIUI is the security center that integrates antivirus, memory cleanup, permission management, and traffic control. While some features seem redundant for power users, for beginners, they provide a handy device control tool in one place.

⚠️ Attention: Aggressive energy saving system in MIUI It can force the background applications to close, which can cause notifications from messengers to arrive with a delay.

Despite criticism for having ads in free apps (which can be turned off), MIUI remains one of the most popular shells in the world, and its functional richness often overshadows minor inconveniences, making smartphone use more productive.

HyperOS: The New Era of Xiaomi Ecosystem

HyperOS is not just a new version of MIUI, it's a fundamentally redesigned operating system. While it may look like its predecessor, there's been a huge change under the hood, and the main goal of the development was to create a single platform for all the company's devices, from smart watches and vacuum cleaners to cars and smartphones.

The main technical difference is the kernel: whereas MIUI was based solely on Android’s Linux core, HyperOS uses a hybrid kernel that includes Linux and Xiaomi Vela’s self-written kernel for IoT devices, which has significantly reduced RAM consumption and reduced system file size, which is especially important for smart, resource-constrained devices.

The user interface became smoother and more animated, developers rewrote the rendering engine, which made opening applications and switching between windows more responsive, and the control panel changed, which gave the ability to more flexible customization of widgets and quick access elements.

• 🚀 Optimization: Reducing memory space and reducing processor load.
• 🔗 HyperConnect: Xiaomi’s instant device connection technology for file transfer and collaboration.
• 🖥️ Universality: a single code base for smartphones, tablets, TVs and cars.

The transition to HyperOS is gradual, with flagships first, middlings then budgets. For many users, upgrading to HyperOS will be the first experience of encountering Xiaomi’s new interface philosophy.

Comparative table: MIUI vs HyperOS

To better understand the differences between the old and new shells, consider their characteristics in comparison, which will help users determine their expectations for the upgrade or choose the right model when buying a new smartphone.

As you can see from the table, HyperOS is betting on the ease and connectivity of devices. However, for the average smartphone user who does not have other Xiaomi gadgets, the difference may not be so obvious at first glance, except in speed.

Importantly, functional differences can vary depending on the regional firmware version (Global, China, EEA). Chinese versions often get new features earlier, but may have restrictions on working with Google services without additional customization.

How to find out the shell version and update the system

For many users, the question is how to know exactly what shell is installed at the moment and whether updateability is available to the version, and this information is checked in just a few seconds and is performed through the standard settings menu.

You need to go to Settings, then select About Phone. At the top of the screen, the system logo will be displayed: either MIUI with version number or Xiaomi HyperOS. By clicking on the logo several times, you can see more detailed technical information, including the Android version and the date of the security patch build.

If an update is available, a button or notification will appear next to the version number, and if it is not available, you can click on three dots in the corner of the screen and select "Check Updates." Sometimes new versions come in waves, so on one device the update may be available and on another it may not yet be available.

Settings → About Phone → Version MIUI/HyperOS → Three Dots → Update Options

For advanced users, there is the option of manually installing updates via the recovery ROM file.This allows you to update before the official release or switch from the Chinese version to the global one, although the latter method requires unlocking the bootloader and completely resetting the data.

⚠️ Note: Installing firmware from unverified sources or interrupting the upgrade process can lead to a “bricking” of the device. Use only official files from miui.com or the built-in bootloader.
