How to watch the Android version on the phone Xiaomi Redmi Note 7

Owning the popular Xiaomi Redmi Note 7 smartphone often requires users to accurately identify the software installed on the device, which may be necessary to check the relevance of security, compatibility with new applications or before the firmware reflashing procedure.Knowing the exact revision of the operating system avoids errors when installing third-party modules or patches.

The MIUI shell interface used by the manufacturer has its own navigation features that differ from pure Android. Therefore, standard paths to information may not be obvious to the beginner. In this article, we will discuss in detail all the ways to get information about the software part of your gadget, from basic settings to engineering methods.

Accuracy is critical, because the build number not only contains information about the kernel version, but also about the region for which the device is intended. An error in determining the type of firmware (Global, CN, EEA) can lead to functionality failure or blocking banking applications. Let's examine in detail where this information is hidden.

Basic method through the settings menu

The easiest and most affordable way to find out the version of the operating system is to use the standard smartphone settings menu, which does not require you to connect to a computer or install additional software, just unlock the device screen and find the appropriate item in the list of parameters.

Once you log in, you'll need to find a section that can be called differently in different versions of MIUI, usually "About Phone" at the top of the list or in the System sub-menu, and if you click on it, you'll see a brief summary of the device's information, including the processor model and the amount of RAM.

To get detailed information, you need to click on the line with the version number MIUI. Depending on the current firmware, one click can show a detailed description, or you need to press 7-10 times to activate the hidden developer menu, this is where the version of Android that runs the shell is displayed.

⚠️ Note: Do not repeatedly click on other fields in this menu, as this may cause hidden features to be accidentally activated or debugging settings to reset.

It is important to distinguish between the MIUI shell version and the Android version. The first number (e.g. 12.5) indicates the interface version, and the second (e.g. 10 or 11) indicates the underlying operating system version. For the Redmi Note 7, Android 9 and 10 are relevant depending on the region and type of firmware.

Use of engineering menus and codes

Special diagnostics and technical information about the system can be used for more in-depth diagnostics. USSD-This method allows you to access hidden logs and technical data that are not displayed in the normal interface.

The most useful code for this task is ##4636##. Once you enter the last digit, the menu should open automatically, without having to press the call button. If this does not happen, then the function is blocked by the operator or firmware. From the menu that opens, select "Phone Information".

In the information section, you will find detailed network status data as well as the software version. This often provides more detailed build information, including the date of the kernel compilation, which is useful for determining whether your firmware copy is official or modified.

• 📱 Code #4636## opens the test menu.
• 🔍 Select the "Phone Information" section to view the data.
• 📝 Write down the build number to search for drivers or firmware.
• 🚫 Do not change the settings in the "Preferred Network Type" menu without the need to.

There is also a code ##6484## that runs the full code. CIT-Although designed primarily for hardware testing, some firmware versions in the Version section contain duplicate system information, a menu often used by service centers.

💡

If the codes don’t work, try entering them in the Phone app immediately after the device is restarted before the system has loaded third-party blockers.

Analysis of information through ADB and computer

For advanced users who lack standard methods, there is a way to get information through the Android Debug Bridge debugging bridge (ADB). This method requires connecting the smartphone to the computer through USB-It allows you to get honest data directly from the system.

Before you start, you need to activate the developer mode. To do this, go to the settings, find the MIUI Version and click on it 7 times. After the message "You became a developer", a new section will appear in the menu "Developers" and you need to include the item "Debug by USB".

Connect the Redmi Note 7 to your PC and run the command line in the ADB tool folder. Enter a command to display all system properties. The system will request permission to connect on the phone screen — confirm it. After that, the console will display a list of all parameters.

adb shell getprop | grep version

This command will filter out the output and leave only the lines containing the word "version." You will see the lines ro.build.version.release (the Android version) and ro.miui.ui.version.name (the MIUI version), which is the most reliable method, since the data is read from system variables that are difficult to forge.

Third-party diagnostic applications

If you don't want to mess with settings and codes, you can use specialized applications from the Google Play store. There are many utilities that collect complete information about the hardware and software of the device, and they provide data in a convenient, structured way.

One of the most popular and trusted applications is CPU-Z or AIDA64. Once installed and launched, the program automatically scans the system and issues a report. The "Device" or "About System" tab contains the desired information about the kernel version, Android API and build number.

The advantage of these apps is that they show not only the OS version, but also the actual processor frequency, sensor temperature and battery status, making them a useful tool for comprehensive diagnostics of the Redmi Note 7, especially when buying a used device.

Note that some apps may be asking for excessive permissions. Use only proven high-rated utilities. For a simple check of the Android version, the free version of CPU-Z is enough, which does not require registration and additional settings.

Differences in versions for different regions

It is important to understand that Xiaomi Redmi Note 7 was released with different types of firmware depending on the region of sales. the Global version (Global) differs from the Chinese (CN) or European (EEA) not only in language, but also in the set of preinstalled services and frequency of updates.

Chinese versions often receive Android updates earlier, but may not have Google services built in, requiring manual installation. Global versions are more stable with local frequencies, but updates come with a delay. Build number helps identify the region: letters at the end of the code indicate the target market.

For example, the end of MI indicates the global version, CN indicates the Chinese version, and EUX indicates the European version. When you change the firmware region (cross-flash), the Android version may change, but this requires unlocking the bootloader. Without unlocking, you can officially install the firmware in another region.

⚠️ Warning: Attempting to flash the device with firmware from another region without unlocking the bootloader can lead to a complete system failure (brick).

Regional verification is also important for functions such as NFC or Mi Pay. In Chinese firmware, the NFC module may work differently or not at all with Russian or European cards, so knowing the exact version of the firmware helps you understand why a particular feature does not work.

💡

The letter index in the build number (e.g. MI, CN, RU) determines the region of the firmware and the availability of Google services.

Frequent questions and definition problems

Users often face a situation where the version number does not change after an update, or the system reports that there are updates even though the latest version is installed, this may be due to the peculiarities of the MIUI servers or the caching of data on the device.

Sometimes the Android version in the settings is not displayed correctly after installing custom themes or modifications to the system interface, in such cases, it helps to clear the cache of the Settings application or reset the interface settings. If the problem persists, it is worth checking the integrity of the system files.

Another common problem is the confusion between the security patch version and the OS version. Security patches can be updated monthly, while the Android version (for example, 9 to 10) changes less often and marks the release of a major update of functionality.
