Chinese brand gadget owners often wonder about the software basis of their devices, not just idle curiosity, but a need to understand the capabilities of the device. The operating system is the foundation on which all user interfaces and applications are built, without which the smartphone becomes a useless piece of plastic and glass.
The answer to the question of which OS is on Xiaomi, has two layers. The basic layer is always Android from Google, which ensures compatibility with millions of applications in the Play Market. But on top of this base, the company installs its own shell, which radically changes the appearance and functionality.
For a long time, MIUI was a brand that became synonymous with the brand and made it stand out from the competition. But at the end of 2023, a historic shift to a new platform called HyperOS began. This change marks the company's transition to a single ecosystem that includes not only phones, but also cars and a smart home.
Understanding the differences between a naked Android and a proprietary add-on is critical: the kernel version is critical to supporting new security features and optimizing the processor, and the user needs to know which system they are dealing with to properly configure the device.
Basic Platform: The Role of Android in Xiaomi’s Ecosystem
The foundation of any modern Xiaomi smartphone is the Android operating system, an open source software developed by Google, and it is the presence of Android that ensures that you can install WhatsApp, Telegram, banking apps and games from Google Play on your phone.
The core version directly impacts performance. Newer versions of Android, such as 13 or 14, offer improved memory and privacy management. Xiaomi smartphones receive base platform updates along with shell updates. However, the rate of arrival of new versions of Android depends on the device model and region.
It’s important to distinguish between pure Android (like the Pixel) and adapted. Xiaomi engineers are making deep changes to the system’s code to implement their features, which allows for heavy games to run on medium hardware, but sometimes raises questions from purists who love Google’s original interface.
⚠️ Attention: Install custom firmware based on pure Android (AOSP) Xiaomi devices require unlocking the bootloader, which cancels the warranty and can lead to data loss if the procedure is performed incorrectly.
Version compatibility is key. The MIUI or HyperOS shell is always tied to a specific version of Android. For example, MIUI 14 was based on Android 12 and 13, while HyperOS is already built on Android 14. Xiaomi's latest flagship models are released immediately with the Android 14-based HyperOS preinstalled.
Evolution of the interface: from MIUI to HyperOS
Xiaomi’s software history goes from simple customization to creating its own operating environment. For years, users knew the brand through the acronym MIUI. This shell offered unique features that competitors didn’t have, such as second spaces and advanced themes.
With MIUI 12 and 13, the company has been focusing on visuals and privacy, with new transparency effects, improved animations and control center, but with the growing number of devices in the ecosystem, it has become clear that the old architecture is not enough to connect a phone, tablet, watch and car.
HyperOS (or HyperOS 1.0) has been the answer to these challenges: it's not just a renaming, it's a deep code reworking, it's lighter, faster and more versatile, and it combines the Linux kernel and Xiaomi Vela's own kernel for IoT devices.
The transition has affected different models in different ways, with flagships being the first to be updated, while budget models may stay on MIUI 14 for a long time to come, which is a normal practice to ensure the stability of older hardware.
- 🚀 HyperOS allows you to instantly transfer files between your Xiaomi phone and your laptop or tablet without setting up a network.
- 🎨 Design: The system of fonts and icons has changed, becoming more minimalistic and adaptive to content.
- ⚙️ Optimization: Reduced system file size, making room for user data and photos.
Key differences between MIUI and HyperOS
Users are often confused about versions, because visual changes may not be obvious at first glance. However, there have been significant changes under the hood. The main difference is in the architecture and development goals. If MIUI was designed as the best interface for a smartphone, HyperOS is designed as an interface for human life among devices.
Performance is one of the big trump cards of the new system, because of the rewritten task scheduler, applications start faster and background processes consume less power, and this is especially noticeable on devices with mid-level processors, where every megahertz counts.
Data security has also been upgraded, with HyperOS implementing more stringent encryption and application access control protocols for the camera and microphone, and privacy indicators becoming more visible and informative to the user.
What's going to happen to old MIUI?
The comparison table will help to understand the technical nuances:
| Characteristics | MIUI (versions 12-14) | HyperOS (1.0 and newer) |
|---|---|---|
| Base core | Linux (Android) | Linux + Xiaomi Vela |
| System size | Up to 12GB (bloating) | About 9GB (optimization) |
| Device communication | Mi Interconnectivity | Xiaomi HyperConnect |
| Animation. | Standard. | Improved, with 120Hz support |
Despite the benefits, some users have noted that they are getting used to the new arrangement of elements, the notification center and the control curtain have been redesigned, which takes time to adapt, but in the long run is considered more convenient.
How to find out the version of the system on your device
To understand which version of the software is installed on your gadget, you don't need to be a programmer, all the necessary information is hidden in the standard settings menu, accessed through the main screen or notification curtain.
The sequence is simple and the same for most models: you need to find the gear icon. In the list that opens, look for the "About the phone" item, which contains all the technical information about the device, including the processor model and the software version.
☑️ Software version check
Inside the About Phone section, you're interested in a line with the shell name, which will say, for example, "MIUI Global 14.0.5" or "HyperOS 1.0.2." Below, in small print, is usually the version of Android on which this build is based.
You can also use the code for the engineering menu, although it's less informative for the average user. Entering the combination ##64663## will open a test menu where you can see the build details in the Version section, but standard settings are enough to check easily.
⚠️ Warning: Do not try to change the values in the engineering menu unless you know exactly what they are responsible for.This can lead to incorrect sensor operation or screen calibration.
Checking for updates regularly is a good habit. The same About Phone menu has a three-dot button or update icon, and by clicking on it, you can manually request a check for a new firmware version.
Update process: risks and recommendations
Updating the operating system is not just about new features, it's also about security patches. Xiaomi regularly releases patches for vulnerabilities. Ignoring updates can leave your phone vulnerable to new viruses and threats.
The upgrade process can be done in two ways: OTA (over the air) and manually through a firmware file. The first is the most secure and recommended method for most users. The system downloads the package itself and suggests installing it.
When updating manually, it is important to be careful: the firmware file should be designed strictly for your model, and installing firmware from another device can lead to “bricking”, that is, complete inoperability of the smartphone.
💡
Before a major upgrade (such as a MIUI on HyperOS), make sure to back up your important data to your computer or the cloud. Even with a regular update, the risk of data loss is always there.
Battery charge is critical. Before you start installing updates, make sure the phone is at least 60 percent charged.
- 📶 Wi-Fi connection: Use stable Wi-Fi to download, as service packs can weigh several gigabytes.
- 🔋 Energy saving: Turn off the power saving mode before installation so that the process is not interrupted by the system.
- 💾 Free space: Make sure that the internal drive has at least 5-10 GB of free space.
After installing a major update, the system can run slower in the first hours, this is the process of optimizing applications and cache, and you should not panic if the phone warms up or discharges quickly immediately after the update.
Frequent problems and ways to solve them
Even the most stable operating system is not without bugs. Xiaomi users sometimes experience problems after an upgrade, it can be a quick battery drain, heating or disappearing contacts, in most cases these problems are solvable.
One of the common problems is a bootloop, and if the phone is stuck on Xiaomi or Mi logos, reset to factory settings via Recovery Mode, you need to press the combination of volume and power buttons when the device is off.
Autonomy issues are often solved by cleaning the system cache, and there are built-in optimization tools in the Security menu, and removing long-unused applications that may conflict with the new OS version also helps.
💡
Most software failures after the update are solved by completely clearing the cache or resetting the settings. If the problem persists for more than 3 days, you should contact the service center.
In some cases, a complete reset (Wipe Data) helps, and it is important that you save all the important data before you do this, because it will be permanently deleted, and it is a radical but often effective method of treating software bugs.
If the phone stopped seeing the network or Wi-Fi after the upgrade, check the date and time settings. An incorrect date can block network protocols. Resetting the network settings can also help restore the connection.
