Modern Huawei smartphones are complex devices where software plays a key role in performance and security. Users are often faced with the need to find out the exact version of the operating system or firmware build number. This may be required when installing specific applications, diagnosing errors, or before contacting a service center to clarify the compatibility of spare parts.
Unlike stock Android, Huawei devices run a proprietary shell EMUI or a new one HarmonyOS, which sometimes complicates the search for information in standard menus. The settings interface may differ depending on the model year and regional version of the device. However, the basic principles of navigation remain similar for most gadgets from the Chinese manufacturer.
Below we will look at all available methods for identifying software: from simple visual checks to the use of engineering codes. You will be able to determine not only the major version of the system, but also the exact build number, as well as the level of security patches, which is critical for assessing the vulnerability of your device.
Checking through the “About Phone” menu
The most obvious and reliable way to get information about the system is to visit the standard settings section. This menu displays all the key characteristics of the device, including the processor model, the amount of RAM and, of course, the software version. To begin, unlock the screen and find the Settingsicon, which usually looks like a gear.
Scroll down the list of options to the very bottom. There you will see the item About the phone or System, depending on the interface version. By clicking on it, you will be taken to a summary table of characteristics. Pay attention to the line EMUI version or Version HarmonyOS —this is where the current firmware number is indicated.
Users often confuse the shell version with the Android kernel version. To see hidden information about the system base, you must perform a certain action. Find the line with the build number and quickly click on it several times (usually 5-7 clicks). After this, a window will pop up on the screen with additional technical information, where it will be indicated Android version.
If the “Android Version” field does not appear after repeated clicks, try holding down the line with the build number for 3-5 seconds instead of quick clicks.
The interface may vary slightly depending on the model. For example, on older devices of the P or Mate series, information can be placed in a separate subsection, while on newer models of the Nova series it is integrated into the main menu of the device properties.
Using the “Support” application
All Huawei smartphones have a proprietary application preinstalled Support (Support). This tool was created not only to communicate with customer care, but also to deeply diagnose the device. It provides more detailed information about the system status than the standard settings menu.
Run the application Support from the general list of apps. On the main screen, select section My phone or Diagnostics. Here you'll see a summary of your battery, memory, and software status. The system will automatically check the relevance of your firmware and compare it with the latest available releases for your model.
In the device information section, not only the version number is often indicated, but also the date of the last security update. This is an important metric that shows how protected your phone is from modern viruses and exploits. If the security update date is older than six months, you should think about looking for new patches.
⚠️ Attention: The “Support” application requires an Internet connection for some functions to check for updates to work correctly. Make sure that Wi-Fi or mobile network is active before starting diagnostics.
This application also has an update log where you can view the history of firmware changes. This is useful if, after the last update, the phone began to work incorrectly, and you want to understand exactly what changes were made by the developers.
Diagnostic codes and engineering menu
For advanced users, there is a way to obtain information through special USSD codes or engineering menu codes. This method allows you to access hidden hardware tests and deeper system parameters that are not visible in the regular interface.
Open the application Phone (dialer) and enter the following code: ##2846579##. After entering the last star, the ProjectMenu will automatically open. Select item Single Version Info or Software version. Here you will see a detailed breakdown of all firmware components.
In this menu you will see a division into CUST (regional part), PRELOAD (pre-installed software) and the system itself. This allows you to understand whether the firmware has been replaced with a custom or global version unofficially. Here you can also see the IMEI and serial number of the device.
##2846579## -> Single Version InfoBe careful when navigating the engineering menu. Changing settings in other sections (for example, Factory Reset or USB Port Settings) without understanding the consequences can lead to data reset or loss of communication with the computer.
What to do if the code does not work?
If entering the code does not bring up a menu, your firmware version may be blocking access to engineering functions for security reasons. Try entering the code in the Phone app rather than searching for settings.
Analysis through Developer Settings
Developer mode is a hidden section of settings designed for debugging applications and testing features. Enabling this mode also provides access to additional technical data about the system, which can be useful in diagnostics.
To activate this mode, go to Settings → About phone and find the item Build number. Quickly click on it 7 times in a row. A notification will appear indicating that you have become a developer. After this, a new item will appear in the main settings menu, usually in the “System” section For developers.
Inside the developer menu you can find information about running services and memory usage in real time. Although the direct version of Android is not always duplicated here, this section allows you to evaluate the stability of the system. For example, the section Process statistics will show which services consume the most resources.
| Parameter | Where to find | Why do you need it |
|---|---|---|
| Number assembly | About the phone | Exact firmware identification |
| Security level | About the phone / Support | Data security assessment |
| Basic version | Engineering menu | Software authentication |
| System kernel | Click on version | Detect Android version |
Mode the developer does not change the version of the system, but provides tools for monitoring its operation and finding the reasons for the brakes.
Detecting the version at boot and in Recovery
Sometimes the operating system does not boot, and it is impossible to check the version through the settings. In such cases, information can be obtained when turning on the device or through the recovery menu (Recovery Mode). This is especially true when trying to flash a brick.
When you turn on the phone, immediately after the Huawei logo appears, on some models the firmware version number is briefly displayed in the lower corner of the screen. It’s difficult to read it in time, but you can take a slow-motion video on another phone to see the details.
A more reliable way is to enter Recovery mode. Turn off your phone completely. Then press the Volume up and Powerbuttons simultaneously. Hold them until the logo appears, then release the Power button while continuing to hold the Volume down. In the recovery menu, the system version is usually indicated at the top of the screen or in the item Version.
- 🔍 In Recovery mode, navigation is carried out with the volume buttons, and selection is done with the power button.
- ⚙️ Not only the version is displayed here EMUI, but also the Android Recovery version.
- 🛑 Do not select the Wipe Data option if you do not want to lose all the files on the phone.
⚠️ Attention: Entering Recovery Mode on some new models with HarmonyOS may require connecting the USB cable to the computer or charger before pressing the buttons.
Checking via computer and ADB apps
For the most accurate data, especially if the phone screen is broken or does not respond to touches, you can use a PC connection. The utility ADB (Android Debug Bridge) allows you to obtain complete information about the system through the computer command line.
USB debugging mode must first be enabled on the phone (in the developer menu). Connect your smartphone to your computer with a cable. Open the command line on your PC in the folder where ADB is installed and enter the command to query the system properties.
adb shell getprop ro.build.version.releaseThis command will display the blank Android version number (for example, 10, 11, 12). To get the EMUI build version, use the command adb shell getprop ro.build.version.emui. This method eliminates any visual distortion of the interface and shows data directly from system files.
☑️ Preparing for testing via ADB
If the phone is not detected by the computer, check the cable and try another USB port. Also make sure that permission to debug from this computer appears on the phone screen and confirm it.
Frequently asked questions about Huawei software versions
Why do I not have updates, although a new version has already been released?
Updates come in waves and depend on the region, model and current version of the database. Sometimes you need to manually check for updates in the menu Settings → System → Software Update. Also, clearing the cache of the “Support” application can help get the current list.
Is it possible to roll back the version of Android to an older one?
Officially, Huawei prohibits version rollback (Downgrade) for security reasons. Trying to do this through third-party tools may result in a completely locked bootloader or loss of data. You can return the old version only to an authorized service center.
What is the difference between EMUI and HarmonyOS?
HarmonyOS is an evolution of EMUI with a modified kernel and improved work with the ecosystem of devices. Visually they are very similar, and the version checking methods remain identical. For the user, the difference lies in the speed of work and the distribution of tasks between gadgets.
How can I find out if the firmware on my Huawei is original?
Compare the build number in the “About phone” menu with the number on the device box (if it is preserved). Also check for Huawei branded apps (HiCare, Galaxy/AppGallery). The absence of standard applications or the presence of Google Play on new models without GMS services may indicate a flashing.
Does the Android version affect the operation of banking applications?
Yes, many banking applications require a certain level of security patches and a minimum version of Android. If the system is outdated, the application may not start or may work with limitations. Regular updates close vulnerabilities that are critical for financial transactions.
