Xiaomi smartphone owners often come across the acronym MIUI when buying or operating a device, and many users mistakenly believe it is a separate operating system or just a third-party app that can be removed, but in fact, the situation is much more complicated and interesting, since MIUI is a deep modification of standard Android.
Understanding this shell is critical for any device owner who wants to make the most of their device, not just a skin or a set of icons, but a complete ecosystem that determines how you interact with the hardware of the phone. In this article, we will examine the architecture of the system, its capabilities and answer the main question: can you live without it?
It’s worth noting that for most users, replacing this shell with a “clean” Android or other alternative can be a fatal mistake. The specific drivers and optimizations introduced by the company’s engineers are closely related to the functionality of HyperOS and previous firmware versions, so before any experiments, you need to be clear about what exactly you are trying to change in the software of your device.
The essence of the shell: operating system or superstructure?
It is fundamental to understand the technical difference between the basic operating system and the user interface. MIUI (pronounced "Mi Yu Ai") is based on the Android kernel developed by Google. However, Xiaomi has redesigned the visuals and system services so deeply that the device feels like a product with a unique operating system.
Unlike standard Android, where the interface is minimal, the shell offers a huge set of additional features out of the box, which includes advanced memory management tools, built-in antiviruses, app cloning, and powerful visual customization tools that work on top of the Android core code, but hide it from the eyes of the average user.
⚠️ Note: Attempting to remove system components MIUI through root rights or ADB-commands without proper preparation can lead to a “brick” of a device, since system processes are interdependent.
The company’s developers update their platform every year, adding features that don’t appear in Android stock until years later or at all. For example, a second space or call recording with automatic identification of the interlocutor was introduced here long before the appearance of competitors, which makes the shell not just a decoration, but a functional extension of the smartphone.
Key differences from standard Android
The main visual difference is that there is no default app menu (although it can be enabled in settings).All program shortcuts are located on desktops, like in iOS, which creates a certain aesthetic and logic of use. In addition, the control center here is divided into two parts: a curtain with notifications and a separate panel with Wi-Fi switches, Bluetooth and brightness.
System applications have also been completely replaced by proprietary software from the company, and instead of a Google calendar, you'll get a Xiaomi-style version, instead of a standard gallery, a powerful app with a built-in editor and hidden albums, which allows for deep service integration, but can scare off those who are used to the Google ecosystem.
- 📱 Design themes: built-in store with thousands of free and paid themes that change icons, fonts, sounds and system animations.
- 🔒 Security: Built-in virus scanner, garbage cleanup, and permission management work at the kernel level, not as third-party apps.
- 📂 File Manager: has access to hidden system folders and can open files of any formats without installing additional software.
- 🔄 Updates: Updates are made weekly (for enthusiasts) or monthly, ensuring quick security patches are received.
Another important aspect is energy management: MIUI’s aggressive background policies allow Xiaomi smartphones to stay on a single charge longer than many competitors, automatically “sleeping” applications you haven’t used in a long time, keeping the battery power for active tasks.

If you don’t like the standard launcher, you can install Nova Launcher or Microsoft Launcher from Google Play to bring back the usual app menu without giving up the system’s features.
Functional capabilities and advantages of the system
One of the most popular tools is Second Space, which allows you to create a virtual second phone inside a smartphone with a separate set of apps, passwords and photos, which is perfect for separating work and personal life, or for handing the device over to your children without the risk that they will delete your important files.
Also worth highlighting are advanced control gestures: navigation in MIUI is considered one of the most convenient on the market; swipes from the edges of the screen allow you to instantly switch between applications, go back or call the multitasking menu; the speed and smoothness of animations here often exceeds that of even more expensive devices from other brands.
Game Turbo is a mode for gamers and active users, not only blocking notifications, but also reallocating CPU and RAM resources to the running game, which allows for more stable FPS and reduces the heating of the case during long gaming sessions.
| Function | Description | Availability |
|---|---|---|
| Second space | Creating an isolated user profile | All versions. |
| Game Turbo | Optimizing performance in games | Mid and flagship segment |
| Cloning of applications | Launching two accounts in one application | All versions. |
| Screen recording | Built-in function without time limit | All versions. |
| Screenshot with three fingers | Quickly create a screenshot swipe | User-configured |
The smart home integration is also worth noting: Mi Home, or its equivalent, is often already built into the system at the widget and quick setup level, allowing you to control light bulbs, robot vacuum cleaners and surveillance cameras directly from the lock screen or notification curtain without running heavy applications.
Can I remove MIUI and replace it?
The issue of removing the shell is a challenge for users who want to experience a clean Android, Google Pixel or Motorola device. Technically, you can't remove MIUI completely, because it's part of the firmware. However, it can be replaced with custom firmware (Custom ROM).
The replacement process requires unlocking the bootloader, which is officially authorized by the company, but takes at least 7 days to wait. Once unlocked, the user can install firmware such as LineageOS, Pixel Experience or ArrowOS. This will give a clean interface and fresh versions of Android, but will deprive many of the unique features of Xiaomi.
Risks of installing custom firmware
There's also a less radical method, which is using third-party launchers, and by installing an alternative launcher, you only change the desktop look and menu, but the system settings, the notification curtain, and the power menu will remain MIUI-style. It's a safe way to diversify the interface without risking the system.
⚠️ Note: Installing custom firmware requires you to follow the instructions for your specific model.Redmi Note 10 firmware won't work on the Redmi Note 9 and vice versa, which can cause a touchscreen or modem to fail.
Setup and optimization for comfortable work
To make the system work as quickly as possible and not annoying with advertising (in global versions), you need to make an initial setup, first of all, you should disable the MSA (MIUI System Ads), which is responsible for displaying advertising materials in system applications.
To do this, go to Settings → Passwords and Security → Access to personal data. Find the msa list and turn off the slider. The system will ask you to wait 10 seconds before confirming - this is a security mechanism. It is also recommended to disable the personalization of advertising in the Security and Themes app.
- 🚀 Memory Extension: Virtual Extension is available in new versions RAM internal memory, which is useful for heavy games.
- 🔋 Battery control: Configure energy saving modes for each application individually so that messengers do not discharge the phone in the background.
- 📶 Wi-Fi Assistant: Enable network acceleration, which automatically switches you to mobile internet if the Wi-Fi signal becomes weak.
Don't forget to check the notification settings. In MIUI, they're divided into "Important" and "Other" and a good sorting will keep messages from loved ones from being missed, but it will keep the advertising fluffs from constantly ringing from stores and games.

Evolution of the interface: from MIUI to HyperOS
In late 2023, Xiaomi began a global renaming of its shell, replacing MIUI 14 with HyperOS, which is not just a name change, but a fundamental redesign of the system architecture. The new OS is built on Android and Xiaomi Vela’s own development, which provides even deeper integration with automotive and IoT devices.
Visually, HyperOS is lighter and more airy, with animated openings, new live wallpapers and widgets, but the basic logic of the controls remains recognizable to millions of users, allowing for a painless transition, and older devices also receive updates, albeit with some limitations of functionality.
The new system focuses on artificial intelligence and cross-platformity, which makes it easier for a smartphone to transfer tasks to a Xiaomi tablet or laptop, creating a single workspace, which means that the question of “what is this program” is gradually transformed into “how does the single ecosystem work?”
💡
The move to HyperOS marks the end of the MIUI era as a standalone shell brand, making it part of Xiaomi’s larger connected smart home system.
