Many users who purchase new smartphones from a popular Chinese brand often wonder what exactly works inside their device. The phrase "Xiaomi miui based on android is like" appears in search queries with enviable regularity, since it is difficult for beginners to understand the software architecture. In essence, MIUI is a deep software add-on that changes the appearance and functionality of the standard operating system, making it unique to the manufacturer's ecosystem.
At the heart of everything is the kernel Linux and base platform Androiddeveloped by Google. It ensures compatibility with millions of applications and operation of hardware drivers. However, “naked” Android looks rather ascetic and is not always convenient for the mass user. Developers Xiaomi take this base and create their own interface on top of it, adding functions that are not in the stock version and changing the logic of interaction with the device.
Understanding this hierarchy is critically important when software failures occur or the need to reflash the device. If you decide to install custom firmware or roll back the system, you will have to deal with exactly this bundle: kernel, base and shell. Removing MIUI system components manually without superuser rights can lead to a complete refusal of the device to start, since many services are rigidly integrated into the system partition.
System architecture: kernel, base and shell
To understand how a smartphone works, you need to imagine its software in the form of a layer cake. The lowest level is occupied by the system core, which directly communicates with the hardware - the processor, camera and communication modules. Above it is a layer Android Open Source Projectthat provides basic capabilities for launching applications and managing files.
The top layer is the shell itself MIUI. This is what you see on the screen: icons, notification shade, settings menu and pre-installed applications. This layer intercepts many system calls and processes them using its own algorithms. For example, power management or working with notifications in Xiaomi are implemented differently than in pure Android, which often causes confusion among those who have previously used other brands.
This multi-level structure gives manufacturers flexibility, but imposes certain restrictions. The security update may come from Google, but the company's developers need to implement it into the MIUI interface themselves. This sometimes leads to delays in receiving the latest security patches compared to Pixel devices.
If you see a message about the Android version in the settings, remember that the MIUI version may be significantly higher, since they are numbered independently of each other.
It is important to understand that the applications running on your phone use both the base system API and specific shell libraries. This allows you to implement unique features, such as advanced app cloning or advanced camera modes, that are not possible in the stock environment without third-party software.
Key differences between MIUI and stock Android
The main visual difference is the absence of a default application menu in older versions and the specific organization of the desktop. In stock Android all installed apps are in a separate menu, and the user places only shortcuts on the desktop. In the classic MIUI all icons are located directly on the screens, as in iOS, although in new versions this logic can be changed in the settings.
System applications have also undergone major redesign. Standard dialers, contacts, gallery and explorer have been replaced with proprietary solutions from Xiaomi. They often have more advanced functionality, such as built-in call recording or a powerful photo editor, but may contain advertising in the free versions. Users accustomed to Google's minimalism often find the interface overloaded.
- 🔋 Aggressive energy saving management: the system independently closes background processes, which sometimes interferes with the operation of instant messengers.
- 🛡️ Advanced Security Center: built-in antivirus and garbage cleaning, which are usually missing from stock or require installation separately.
- 🎨 Deep customization of themes: the ability to change not only the wallpaper, but also the style of icons, fonts and system sounds in a few clicks.
Another important aspect is the notification system. The MIUI implements its own mechanism for displaying pop-up windows and locking the screen, which differs from the standard behavior Android. This may result in notifications from some applications not arriving on time unless you configure special permissions.
It is worth noting that with the release With new versions, the difference is gradually erased. Google borrows some ideas from manufacturers, and Xiaomi seeks to bring its interface closer to international standards, especially in global firmware versions.
Compatibility and optimization problems
Despite the powerful hardware, users often encounter software problems related specifically to the features of the shell. The most common complaint concerns the performance of background applications. The mechanism MIUI strives to save battery power as much as possible, so it can “kill” navigation processes or music players without warning.
To solve this problem, you need to manually configure autorun and no restrictions for important apps. This is done through the battery settings menu, where you need to find a specific application and allow it to run in the background. Without this procedure, you may miss an important call in Viber or Telegram.
⚠️ Attention: In new firmware versions, the location of the energy saving settings may change. If you don't find the item you need in the battery menu, try searching for it through the global settings search by entering the name of the application.
Another common problem is compatibility with Google services. On global versions everything works stably, but on Chinese firmware installation Google Play requires additional steps. Even after installation, conflicts may arise when synchronizing contacts or working Google Pay (now Wallet).
| Problem | Reason in MIUI | Solution |
|---|---|---|
| Notifications do not arrive | Aggressive sleep of applications | Disable energy saving for the application |
| GPS failures | Conflict of localization services | Reset geolocation settings or update software |
| Brakes interface | Theme cache is full | Clearing the "Themes" application data |
| NFC does not work | Incorrect selection of a secure element | Change NFC settings in the connection menu |
It is also worth mentioning the problem with permissions. MIUI requests data access rights more strictly than the stock one Androidwhich, on the one hand, increases security, and on the other hand, requires more attention from the user when initially setting up the smartphone.
The transition from MIUI to HyperOS: what is changing
At the end of 2023 and in 2026, the company Xiaomi began the global introduction of a new operating system called HyperOS. This is not just a name change, but a fundamental redesign of the system architecture, aimed at combining smartphones, tablets, cars and smart home devices into a single ecosystem.
Visually HyperOS maintains continuity with MIUI 14, but becomes lighter and faster. The developers have rewritten many system services, reducing the amount of memory consumed. For the user, this means smoother animation and less RAM consumption when idle.
Technical differences of HyperOS
The system core has been modified to better work with heterogeneous computing tasks. A new resource management subsystem has been introduced that dynamically distributes processor power between active tasks, which is especially noticeable in heavy games and multitasking.
One of the key innovations is improved communication between devices. If you have a laptop or tablet from Xiaomithen HyperOS then the function of instant file sharing and clipboard sharing is implemented without the need for complex setup. This is a direct response to the Apple ecosystem.
The update process for older devices running on MIUIoccurs gradually. Users do not need to erase data; the update comes over the air. However, owners of very old models should check the list of supported devices, as some of them will remain on the final version MIUI without switching to a new platform.
How to check the version and update the system
In order to find out which version of the software is installed on your device, you need to go to the settings. The path usually looks like this: Settings → About phone. Here you will see a large version number MIUI or HyperOS, as well as the basic version Android, which is often hidden in additional menus or indicated in small print.
Checking for updates is a simple procedure, but it requires stable connection to the Wi-Fi network. Go to the menu Settings → About phone and click on the system version icon. The phone will contact the update server and check for new firmware.
- 📲 Make sure the battery charge is at least 30% before starting the installation.
- 📶 Use a stable Wi-Fi connection to avoid file corruption firmware.
- 💾 Back up important data to the cloud or to your computer before major updates.
Sometimes automatic updates do not come to all devices at once due to phased deployment. In this case, you can try to clear the data of the "Software Update" application through the app menu, but you should do this with caution.
☑️ Preparing for a firmware update
⚠️ Attention: If you use an unlocked bootloader or installed a custom recovery, receiving updates over the air (OTA) may be is not available or may result in installation errors. In such cases, the firmware is updated manually via a computer.
Customizing the interface for yourself
Flexibility MIUI allows you to turn your smartphone into a unique tool. You should start with the Themes application, which is the center of customization. Here you can download ready-made sets that change the appearance of icons, lock screen and system fonts in a couple of clicks.
For more advanced users, the “Second Space” mode is available. This feature allows you to create an isolated environment inside one phone with a separate set of applications, photos and settings. Switching between the main and second space occurs using a fingerprint or password, which is convenient for separating work and personal life.
Do not ignore the gesture settings. In MIUI they work differently than in pure Android. For example, swiping up from anywhere on the screen returns you to the desktop, and swiping from the edge returns you back. This will take some getting used to if you are switching from push-button navigation.
Correctly setting up gestures and disabling unnecessary system effects can visually speed up the operation of your smartphone and make control more ergonomic.
The "Quick Notes" function is also available. Swiping your finger diagonally down from the corner of the screen will open a notepad for quickly jotting down thoughts. This is one of those little things that significantly increases the convenience of everyday use of a device based on Xiaomi.
Is it possible to remove MIUI system applications?
Technically, this is only possible if you have root access or through special utilities on the computer (for example, ADB AppControl). However, removing critical system components such as Security or File Explorer may cause your system to become unstable or unable to boot. It is only recommended to disable unnecessary applications in the settings, if such an option is provided.
Why does MIUI consume more memory than pure Android?
Shell MIUI includes many background services for proprietary functions: topics, cloud synchronization, virus protection and optimization. These services take up additional RAM. On devices with 4 GB of RAM or less, this may be noticeable, so for comfortable work with MIUI it is recommended to have at least 6 GB of RAM.
What is the difference between the Global and China versions of MIUI?
The Chinese version (China ROM) is updated faster, contains functions aimed at the domestic market of the PRC, and does not have pre-installed Google services. The global version (Global ROM) is adapted for international use, has built-in Google Play, language support and a modified set of pre-installed software that complies with the laws of other countries.
How to disable advertising in Xiaomi system applications?
Advertising can be disabled by deactivating the service msa (MIUI System Ads) in the settings authorization, as well as by disabling ad personalization in your privacy settings. Each system application (Music, Themes, Explorer) also has its own “Get recommendations” switch, which you need to find and turn off.
Is it safe to install firmware from the w3bsit3-dns.com forum?
Installing custom firmware from forums requires unlocking the bootloader, which will void the warranty. This carries risks: the phone may turn into a brick, the camera or banking applications may stop working. This should only be done by experienced users who understand the consequences and know how to restore the device via Fastboot mode.
