Smartphone Xiaomi Mi 9 SE entered the market in 2019, positioned as an affordable flagship with excellent performance. Owners of this device are often interested in the question of which version of the operating system Android is currently current for this model. Official software support has its own cycles, and understanding what stage your gadget is at is critical to assessing its security and compatibility with modern applications.
Initially, the device came with a shell MIUI 10 based on Android 9 Pie. During its life cycle, the smartphone received several major updates, which is a rarity for many competitors in this price segment. However, like any electronic device, it has its own limits of manufacturer support. In this article we will look in detail at which version you can officially update to Mi 9 SE, what risks exist when installing unofficial firmware and how to check the relevance of your software.
It is important to understand that the Android version number and the MIUI interface version are different things. Users often confuse the two, believing that updating MIUI automatically means upgrading to a new Android. In fact, security updates interface patches can come more often than changing the major version of the system kernel. Let's look at the technical details.
Official support and final software version
Xiaomi developers announced the completion of official support for the model Mi 9 SE at a certain stage. The final official version of the operating system for this smartphone was Android 11 with shell MIUI 12.5. This means that there are no official updates to Android 12 or Android 13 from Xiaomi for this device.
Despite the fact that the processor hardware is theoretically capable of running newer versions, the manufacturer has limited support. This is standard industry practice to optimize drivers and ensure stable performance. Users who remain on the official firmware continue to receive only rare security patches, if any, but the functionality of the system remains at the level Snapdragon 712 theoretically capable of running newer versions, the manufacturer has limited support. This is standard industry practice to optimize drivers and ensure stable performance. Users who remain on the official firmware continue to receive only rare security patches, if any, but the system functionality remains at the same level Android 11.
It is worth noting that the MIUI version may have different indexes depending on the region. The global version (Global ROM) and the Chinese version (China ROM) can be updated at different speeds and have a different set of pre-installed services. For users outside of China, the global build is most often available, which is stabilized later, but lacks Chinese system software.
⚠️ Attention: Official support for updates for the Mi 9 SE has been completed. New functions available on the latest Xiaomi models cannot appear on this device through official channels.
The final official version for Mi 9 SE is Android 11 (MIUI 12.5). Newer versions of Android are only available through third-party firmware.
How to check the current version of Android
Before taking any action to update or change the firmware, you need to know exactly what software is currently installed on your device. The Android system provides built-in tools to obtain this information. This will help you understand whether you need to update or are already on the latest version available.
The verification process is quite simple and does not require a connection to a computer. You need to go to your phone's settings and find the section containing device information. The interface may differ slightly depending on the installed version of MIUI, but the navigation logic remains the same for all Xiaomi smartphones.
Follow the following steps to get accurate system data:
- 📱 Open the application
Settingson the main screen. - 🔍 Scroll down and select
About phone. - 🤖 Find the line Android version —the number will be indicated there (for example, 9, 10 or 11).
- 🎨 Next to it will be indicated MIUI Version, which indicates the version of the proprietary shell.
Also in this menu you can click on the logo several times in a row MIUIto activate additional developer functions, if necessary for debugging However, to simply check the version, just look at the numbers provided. If you have a version lower than 11 installed and you want to stay on the official software, you should check for updates through the built-in updater.
The process of updating to the latest official version
If checking showed that you have an outdated version installed, for example, Android 9 or 10, you can try to update to the final official version. Xiaomi provides a convenient over-the-air (OTA) update mechanism that allows you to download and install new firmware without using a computer.
Before starting the procedure, it is critical to prepare the device. Firmware upgrade is the process of writing system partitions, and any power interruption or communication failure can lead to serious consequences. Make sure that the battery charge is at least 60%, or better yet, connect the smartphone to the charger during the entire process.
To start the update, go to the menu Settings → About phone → System update. Press the button Check for updates. If Xiaomi servers find available firmware for your region and device, the download will begin. After loading, the system will prompt you to reboot and install the update.
☑️ Preparing for a system update
Sometimes the automatic update does not arrive immediately. This may be due to the fact that the update is rolling out in stages to different users. In this case, you can try to manually check for updates or download the official firmware package from the Xiaomi website and install it via Recovery mode.
⚠️ Attention: When updating via Recovery using an SD card or internal storage, the firmware file must have the extension
.zipand be placed in the root of the storage without renaming.
Installing custom firmware (Custom ROM)
For enthusiasts who are not satisfied with stopping at Android 11, there is an alternative - installing custom firmware. The developer community of XDA and other resources continues to support Mi 9 SEporting more recent versions of Android to it, such as 12, 13 and even 14 based on the LineageOS, Pixel Experience or crDroid projects.
This path requires certain technical knowledge and skills from the user. The procedure includes unlocking the bootloader, installing a custom recovery (usually TWRP) and subsequent flash installation of the new system. This allows you to get a clean Android without unnecessary Xiaomi applications and fresh security patches.
However, installing unofficial software carries a number of risks and limitations:
- 🔓 Unlocking the bootloader officially erases all data from the device.
- 🚫 Banking applications and payment systems (Google Pay, Mir Pay) may stop working due to SafetyNet/Play Integrity protection being triggered.
- 📸 The quality of the camera may deteriorate, as stock photo processing algorithms from Xiaomi are lost.
If you decide to take this step, carefully study the profile of your device on the developer forums. Look for stable builds (Stable), not nightly (Nightly), if you plan to use the phone as your main device. Always make a full backup of the EFS partition so as not to lose IMEI and the ability to work with the network.
What is bootloader unlocking?
Unlocking the bootloader is a procedure for removing manufacturer restrictions on software installation. On Xiaomi, this requires sending a request through a special Mi Unlock utility and waiting from 3 to 7 days. The process irreversibly deletes all user data from the phone.
Comparison of Android versions on Mi 9 SE
To clearly understand the difference between the versions that have passed Mi 9 SE during its life, let's look at the main changes. Moving from one major version to another usually brings not only a new visual style, but also changes in the management of permissions, privacy and background processes.
Below is a table showing the evolution of the software on this device. Please note that switching to new versions of Android often required updating hardware drivers, which sometimes affected battery life.
| Android version | MIUI version | Key features | Support status |
|---|---|---|---|
| Android 9 (Pie) | MIUI 10 / 11 | Basic system, navigation gestures | Outdated |
| Android 10 | MIUI 12 | Dark theme, improved privacy | Outdated |
| Android 11 | MIUI 12.5 | Permissions for one session, chat bubbles | Final official |
| Android 12+ (Custom) | Without MIUI / Custom | Material You, new widgets | Unofficial |
As can be seen from the table, the final official version brought important functions for controlling access to the microphone and camera, which is relevant in the modern realities of digital security. Switching to custom versions provides visual novelty, but may deprive you of the stability inherent in the factory build.
Before switching to custom firmware, check the operation of NFC. On some custom builds for Mi 9 SE, the contactless payment module may not work correctly or require additional patches.
Frequent problems after updating and their solutions
Updating the operating system, especially a major one, sometimes causes side effects. Users Mi 9 SE may experience increased battery consumption, case heating, or incorrect operation of some applications immediately after installing a new version of Android or MIUI.
Often these problems are due to the fact that the system performs background application optimization and file indexing. This process can take from several hours to a couple of days. During this period, you should not panic and try to reset the settings right away. Give your smartphone time to adapt to new operating conditions.
If problems persist for a long time, you should pay attention to the following points:
- 🔋 Check the battery consumption statistics in the settings to find the parasitic application.
- 🗑️ Clear the cache of system applications through Recovery mode or settings storage.
- 🔄 As a last resort, perform a factory reset (Hard Reset), pre-saving important data.
A factory reset is the most effective way to resolve software conflicts after an update. It deletes all old configuration files that could remain from the previous version of the system and cause errors in the new one.
⚠️ Attention: A factory reset completely deletes all your personal data, photos, contacts and applications. Be sure to create a backup in the cloud or on your computer before this procedure.
FAQ: Frequently asked questions
Is it possible to update Xiaomi Mi 9 SE to Android 13 officially?
