What is MIUI on Xiaomi: the analysis of the system

When you first pick up a new smartphone from a Chinese giant, you'll notice that it's very different from other brands. Many people wonder, what is this app and why does it take up so much memory? In fact, it's not just one of many programs that can be removed to free up gigabytes. It's a profound modification of the Android operating system that completely changes the visual style and logic of interaction with the device.

The developers have created a unique ecosystem that combines the functions of a social network, cloud storage and a smart home management center. Understanding how this software layer works will allow you to squeeze the maximum performance out of your gadget. In this article, we will discuss in detail the architecture of the system, its advantages over stock Android and how to fine-tune it for personal needs.

It is worth noting that the acronym comes from the words MI User Interface, which literally translates as the user interface MI. Over the years, the shell has gone a huge way of evolution, acquiring new features with each update.

The essence and origin of the MIUI shell

The story of this system began more than a decade ago, when a team of enthusiasts decided to remake standard Android to make it more convenient and beautiful. At that time, Android looked quite angular and didn't offer the many customizations we're used to today. Xiaomi engineers took open source as a basis and wrote on top of it their own layer, which is now known around the world.

The main feature was that there was no app menu in the classic sense of the early versions, all shortcuts were on desktops, like iOS, which was a revolutionary step for the time. Today, the system provides the user with choices, but it was this approach that formed the core of the brand's audience.

⚠️ Attention: MIUI It is not a separate operating system, it is based on the Android kernel, so it supports all applications from the Google Play Store.

It’s important to understand that each version of the shell is tied to a specific version of Android. For example, MIUI 14 can be based on Android 12 or 13, depending on the device model, which creates confusion for beginners who can’t figure out how to number security updates and interface versions.

• 📱 The shell runs on top of the Linux kernel, just like standard Android.
• 🎨 Visual style completely changed by the developers of the company.
• 🔄 Updates come more often than many competitors in the market.
• 🛠 Built-in tools allow you not to install third-party software.

Developers are constantly improving the code by adding new features that are later copied by other manufacturers, which is why the interface remains relevant and modern, despite the high competition in the mobile technology segment.

Key differences from pure Android

Users who have switched from Pixel or Motorola devices notice the difference in logic, and pure Android offers minimalism and simplicity, while MIUI is overloaded with features out of the box. You don't have to search and install dozens of programs for basic tasks, because everything is already built into the system.

One of the biggest benefits is deep customization, you can change themes, fonts, icons, even transition animations without getting super-user rights, and MIUI themes are a universe where designers from all over the world create unique visual styles.

Notification management is also implemented differently, with a separation between application notifications and system messages, which helps keep the lock screen clean, and memory optimization is more aggressive, by forcibly closing background processes to save charge.

And there's a lot of advertising in standard apps, which is a price tag for low-cost devices, but as we'll find out later, you can turn it off completely manually, and you can get back the comfort of your use.

Built-in applications and services

It comes with a whole suite of utilities that you might otherwise have to download separately, so-called system applications that provide basic smartphone functionality, many of which run deeper than the store counterparts, with access to secure device features.

The Security app, which combines antivirus, cache cleaning, permission management, and even traffic limit settings, is a special feature, and the optimizer inside this program allows you to free up RAM with a single tap, although modern versions of Android can do it themselves.

Another powerful tool is the Explorer, which is able not only to manage files, but also to connect to cloud storage and storage. FTP-This eliminates the need to install third-party file managers like Total Commander.

⚠️ Note: Do not remove system applications through third-party launchers unless you are sure of their purpose - this can lead to unstable phone operation.

For multimedia enthusiasts, powerful players are pre-installed. The gallery can hide albums with a password and has an embedded editor with AI functions. The recorder is able to recognize speech and save it in text, which is extremely convenient for students and journalists.

• 📞 Call Manager with recording of conversations and determining the number.
• 📅 Calendar with integration of holidays of different countries.
• 🔦 Flashlight with customizable blinking modes.
• 🧮 Calculator with converter of values and currencies.

All of these tools are united by a single design and work faster than their counterparts from the Play Market, as they are optimized specifically for Xiaomi hardware.

Interface setting and personalization

The possibilities of changing the look in this shell are almost limitless, and you can start by installing a new theme through the Themes app, and there are thousands of customization options available that change the wallpaper, icons, sounds, and even the fonts of the system.

For a more subtle setup, there's an "Always on Screen" menu, so you can choose the clock that will show up when the display is off, or upload your image. The lock screen is also editable, so you can add pedometer widgets, battery status, or a quick camera start.

Of particular interest is the "Second Space" feature, which allows you to create another fully independent desktop inside your phone, which is ideal for separating work and personal life, or for handing the device over to your children without risking access to your data.

And widgets, too. In MIUI, they're interactive and can be quite large, taking up half the screen, and widgets allow you to control music, see the weather, or see a task list without opening the apps.

If you don’t have enough standard options, there are third-party launchers, but the native shell offers enough functionality for most users. The main thing is not to be afraid to experiment with settings in the Settings → Wallpaper and personalization menu.

Optimization and Hidden Functions

It's rich in hidden features that not all owners know about, like One Hand mode, which makes the screen smaller, allowing you to conveniently control your thumb with your thumb, and it's activated by triple pressing the menu button or swiping at the bottom of the screen.

Game Turbo is designed for gamers, which blocks notifications, clears the memory before starting a game, and allows you to take screenshots or record a screen without interrupting the process, and you can adjust the sensitivity of the touchscreen for faster response in shooters.

Another useful feature is the quick start of applications, which allows you to set the camera to start when you double press the volume button, and the flashlight when you press the power button, which saves time in critical situations.

⚠️ Warning: The “Game Acceleration” function can increase the temperature of the body, since the processor operates at maximum frequencies.

To save traffic and improve page loading speed, the browser uses built-in data compression technology. Although modern tariffs offer many gigabytes, traffic optimization is still relevant in places with poor network coverage.

• 🚀 Accelerating application launch in the background.
• 🔒 Hiding files in a secure folder.
• 📶 Smart switching between Wi-Fi and mobile internet.
• 👆 Handling gestures in the off state.

All these features make smartphone use more comfortable and efficient, turning a regular device into a powerful tool for work and entertainment.

Frequent problems and ways to solve them

Despite the functionality, users sometimes face problems, and one of the most common is aggressive energy saving, which kills the right applications, which causes no notifications, and this is solved by setting up auto-start and no restrictions in the background.

Another problem is advertising in system applications, which appears as recommendations in folders or as banners, and to turn it off, you need to go to the settings of each application (for example, Music, Explorer) and find the Receive Recommendations or MSA switch in the general settings.

There are also complaints about Bluetooth and GPS, often by updating your firmware or resetting your network settings, and a full factory reset helps in the extreme, but make sure you back up your data before you do that.

If the phone is slow, check the space. The system requires at least 10-15% free memory to work properly optimization mechanisms. Overcrowded drive is the main reason for interface lags.

In most cases, the problems are software-based and solved without going to the service center, the main thing is to carefully study the settings and not ignore system updates.
