Owners of Xiaomi, Redmi and POCO smartphones often face the need to accurately identify the installed operating system, not only when looking for updates, but also when there are problems with the compatibility of applications or banking services. Understanding what software code is running on your device is the first step to competent management of the gadget.
Many users confuse the Android version and the MIUI or HyperOS shell version. These are different levels of software structure, and for a full diagnosis you need to know the parameters of both components. In this article, we will discuss all the available methods for obtaining complete information about the software of your smartphone.
Knowing the exact version of the software is also critical when you go to a service center or a forum, and wizards and experienced users always start the conversation with the question of the build number, because it depends on how you solve the problem, and let's look at where to look for this data and how to interpret it correctly.
Verification through the Settings menu
The most obvious and affordable way to find out about a system is to look at the standard settings menu, which doesn't require you to connect to a computer or install third-party software. All the data is already on your phone, you just need to know where to click.
To start, unlock the screen and find the Settings icon. From the menu list, select About Phone, where you can find the basic technical information about your device, including the processor model, memory capacity, and operating system version.
In the window that opens, you'll see a large number that represents either MIUI or HyperOS. But that's not all. You have to click on that number several times in a row to get detailed information, and after 5-7 quick taps, you'll see an extended menu with additional options.
- 📱 Version. MIUI: the main shell number, for example, 14.0.5.
- 🤖 Android Version: The Basic Operating System That Runs the Shell.
- 🏷️ Version. MIUI for POCO: sub-brand POCO.
- 🔢 Internal number: complete build code including region and release date.
💡
Remember the full build number (e.g. V14.0.3.0.TNRMIXM) and not just the MIUI version.
It's important to distinguish between these options.The Android version shows the capabilities of the system's core, while MIUI defines the visual interface and additional features.A shell update doesn't always mean an Android update, which often causes confusion among beginners.
Decoding the code of the firmware region
One of the most important parts of a firmware ID is the region code, which indicates which market the software is intended for, and what pre-installed services, the availability of advertising, the support of communication frequencies, and even the operation of NFC depend on it.
In the full build number, the last three letters before the last block of numbers and letters indicate the region. For example, in MIUI 14.0.2.0.TNRMIXM code, the combination MIXM tells us about the global version. Knowledge of this code helps us understand why some features may be missing on your phone or, conversely, there are redundant applications.
Why is it important to know the region?
Consider the basic acronyms you might come across in your smartphone settings, and understanding these codes will help you avoid installing inappropriate software in the future.
- 🌍 Global (MI/EU/RU): International version with support for many languages and services Google.
- 🇨🇳 China (CN): A version for China’s domestic market, often without Google services out of the box.
- 🇮🇳 India (IN): adapted to the requirements of the Indian market.
- 🇷🇺 Russia (RU): localized version with pre-installed Russian applications.
Sometimes people buy phones from other countries and they're faced with a lack of Russian or a broken NFC, and checking the region's code gives you an immediate idea of why they're not doing that, and if you see the CN code, you're looking at the Chinese version, which requires a firmware update for comfortable use.
Use of engineering menus and codes
To further diagnose, Xiaomi engineers have provided hidden menus accessible through a set of special codes, a way to access technical information that is hidden from the average user in a standard interface.
To use this method, open the Phone app and enter a special code. The most useful code for our task is ##64663##. It opens the engineering testing menu where you can check the operation of all the modules of the device.
##4636##The code above opens the Testing menu, where you can see more details about the software part, including IMEI and network status, in the Phone Information section, but the standard menu is often enough to view the firmware version, since the engineering codes in new versions of MIUI can be blocked by the operator or manufacturer.
It is worth noting that on some models with the new HyperOS shell, access to the engineering menu may be restricted for security reasons. If the code does not work, do not panic - this is normal for modern versions of software.
Comparison of versions: Global, China and EU
Users often wonder what the different types of firmware differ from regional settings, and the differences can be significant, not just in the interface language, but also in performance, system advertising, and frequency of updates.
Chinese versions (CN) are usually the first to receive updates, and they introduce the latest MIUI features that may or may not be available in global builds later, but they lack the default Google Play Store and require additional manipulation.
| Parameter | Global (Global) | China (Chinese) | EU (European) |
|---|---|---|---|
| Languages | Multilingual | Chinese, English | Multilingual |
| Google Services | Pre-installed | Require installation | Pre-installed |
| Advertising in the system | Yes (can be turned off) | Many. | Absent. |
| Frequency of updates | Standard. | Fastest one. | Depends on the developer. |
European firmware (EU) is often created by independent developers or local distributors, and may lack system advertising and optimizations that are not available in official global versions.
Global versions (Global) are the middle ground for most users, stable, fully language-supported, and certified worldwide, and are recommended for those who don’t want to risk the device’s security or stability.
Checking through computer and ADB
For advanced users who want to get the most accurate and technical information, there is a method of checking through a connection to a computer. Using the ADB (Android Debug Bridge) debugging bridge allows you to request complete build data from the system.
To start, you need to activate the developer mode on your phone. To do this, go to Settings → About Phone and quickly click on the MIUI version 7 times. After that, the menu will appear under “Additional” or “Extended settings”, where you need to turn on “Debugging by USB”.
⚠️ Warning: Be careful when connecting your phone to unfamiliar computers in debugging mode.This gives the device at the other end of the wire wide access to your data.
Connect your smartphone to your computer through USB-And you'll see a request for debugging permission on your phone screen, confirm it, then on the computer where it's installed. ADB, Open the command line and enter the next command:
adb shell getprop ro.build.version.incrementalThis command will output the exact number of the current build, and you can also use the adb shell getprop command, which will give you a huge list of all system properties, where you can find information about the firmware compilation date and its exact identifier.
☑️ Preparation for verification through ADB
This method is especially useful if the phone interface is damaged or not working properly, but the system is still responding to commands, and it allows you to get data even when the settings menu is not available.
Frequent questions and definition problems
When checking a firmware version, users often encounter unusual situations, such as the version number may not match the expected version after the update, or the phone may display information about the previous build.
One common problem is sticking the version after an over-the-air update (OTA) sometimes gets updated, but the old number remains on the menu until the first reboot, in which case it is enough to simply restart the device to update the data.
⚠️ Note: If the version number has not changed after the firmware update, but new features have appeared, you may have received a hidden update of system components, rather than a full shell.
Also, it is worth considering that custom firmware can be disguised as official or have its own naming rules. If you buy a phone from hand, be sure to check the integrity of the system, as unscrupulous sellers can install modified software.
💡
The most reliable way to find out the version is a combination of checking in the About Phone menu and checking the region code with the device box.
Understanding how version numbering works will help you avoid many errors when using your smartphone. Always double-check the information before downloading files for manual installation.
