A modern smartphone is a complex digital device, the management of which requires an understanding of its internal structure. One of the key parameters that determines the functionality of a gadget is the version of the operating system. Users often wonder how to accurately determine which software modification is installed, especially when it comes to application security or compatibility. Knowing the exact build number helps not only in technical support, but also when installing specific software.
In the ecosystem Google there are many shells from different manufacturers, such as One UI from Samsung or MIUI from Xiaomi. These visual add-ons often hide standard paths to system information, confusing inexperienced owners. However, regardless of the brand, system data is always stored in a specific section of the settings. It is important to be able to find this information in order to promptly update your device and protect personal data from vulnerabilities.
In this article we will examine in detail all the possible ways to obtain information about the software of your device. We will look at standard methods through the settings menu, using engineering codes and using third-party diagnostic tools. You will learn to distinguish between the kernel version, security patch level and build number, which will make you a more confident user.
The standard path through system settings
The most obvious and safe way to obtain information about the system is to use the built-in settings menu. The interface may differ depending on the manufacturer, but the logic remains the same for all devices based on Android. Typically, you need to open the main application menu and look for the gear icon. This is where all the device control keys are concentrated.
In pure Android, which can be found on smartphones Google Pixel or Motorola, the path looks as concise as possible. You need to scroll to the bottom of the list and select “About phone” or “System”. In the window that opens, a large number will be indicated indicating the major version of the OS. This is the first level of information that the user sees.
- 📱 Open the Settings application on the main screen or menu.
- 🔍 Find the "About phone", "About device" or "System" section at the very bottom of the list.
- ℹ️ Tap on the "Android version" line to see additional details.
- 🔢 Pay attention to the line “Build number” for precise software identification.
It is worth noting that in some shells, for example ColorOS from Oppo or Funtouch OS from Vivo, the path may be slightly changed. Sometimes you need to click on the line with the Android version several times in a row to activate a hidden menu with more detailed technical information. This security measure prevents inexperienced users from accidentally changing critical parameters.
⚠️ Attention: Do not attempt to change values in the developer menu, which can open after repeatedly clicking on the build number, if you do not understand the purpose of each function. This may lead to system instability.
To obtain more detailed information, such as the release date of a security patch or the Linux kernel version, you often need to go to an additional submenu. In the standard interface Google this is often hidden behind the “Software Information” or “Advanced” item. There you will find information about when your device's security databases were last updated.
⚠️ Attention: Menu interfaces may change after major operating system updates. If you do not find the described items, try using the search inside the settings.
Interface features of Samsung, Xiaomi and Huawei
Large manufacturers electronics companies strive to make their products unique by changing the standard interface Android. This also applies to the location of system information. Understanding the specific shell of your device will significantly speed up the search for the necessary data. Let's consider the features of popular brands.
In smartphones Samsung with a shell One UI the path to information about the system is as follows. After entering the settings, you need to scroll to the very bottom of the list. The “About Phone” section will be located there. Inside it you need to find the line “Software Information”. It is in this submenu that the version Android, the version of the One UI interface and the date of the last security update are displayed.
Devices from the company Xiaomi, working on the base MIUI or the new HyperOS, have their own structure. On the main settings screen, a block with the logo of the shell version is usually immediately visible. To view the version Android you need to click on this logo or find the “About phone” item at the top of the list. Often the amount of free memory and the processor are also displayed there.
Smartphones Huawei and Honor (on older firmware with Google services) use the shell EMUI. Here the path looks like this: “System” → “System update” → menu icon in the upper right corner (three dots) → “Other versions”. In some cases, the information is placed in the “About phone” section, where you need to click on the line with the build number to see the version Android.
| Brand | Shell | Path to Android version | Additional step |
|---|---|---|---|
| Samsung | One UI | Settings → About phone | Click “Software information” |
| Xiaomi | MIUI / HyperOS | Settings → About phone | Click on the MIUI logo |
| Huawei | EMUI | Settings → System | Menu "Others" version" |
| Stock Android | Settings → System | Section "System update" |
It is important to understand that within the same phone model there may be different regional firmware versions. This affects the layout of menu items. If the described path does not match, use the built-in search in the settings by entering the request “About phone” or “Version”.
Use the search inside the settings menu by entering the word “Version” or “About phone” - this is the fastest way to find the desired section in any shell.
Using engineering menu codes
There is an alternative way to obtain technical information that does not require a deep dive into the settings menu. This is the use of special USSD codes or engineering menu codes. They allow you to quickly display service information, including software version, IMEI and testing status.
To activate such a menu, you need to open the “Phone” application through which you make calls. In the dialing field you need to enter a special combination of characters. After entering the last character, the menu should open automatically, without the need to press the call button. This is a convenient way for quick diagnostics.
However, it is worth considering that manufacturers often block access to the full engineering menu in the final versions of firmware intended for ordinary users. Codes may vary depending on the processor (Qualcomm, MediaTek, Exynos) and device model.
- 📞
##4636##— universal code for the testing menu (works on many devices). - 🔧
#0#— often used in devices Samsung for a general test. - 📱
##375##— code for checking SIG (works on some models). - 🛠️
##8255##—launch the GTalk service (on older devices).
If after entering the code nothing happens or an error message appears, then this method is blocked by the manufacturer or is not supported by your model. In this case, you should not download dubious applications that promise to unlock these codes, as this may disrupt the operation of the radio module.
⚠️ Attention: Be extremely careful in the engineering menu. Changing the settings in the “Radio Info” or “Connectivity” sections may result in loss of communication or inability to connect to the mobile operator’s network.
What to do if the code does not work?
If the standard codes do not work, this means that the manufacturer has limited access to the engineering menu for security. In this case, the only safe option is to use the standard path through Settings or install diagnostic applications from the official store.
Third-party diagnostic applications
When standard tools are not enough or the most detailed technical specification is required, specialized applications come to the rescue. In the store Google Play there are many utilities that read data from system files and present them in a convenient form. This is the best way to find out details about hardware and software.
One of the most popular and authoritative applications is CPU-Z or AIDA64. After installation and launch, the app scans the device. The “Device” or “OS” section will indicate the exact version Android, API level, codebase name and, importantly, the level of security patches.
Another powerful tool is the application DevCheck. It provides information not only about the current OS version, but also supported features, sensor statuses, and even whether the device has been rooted. For ordinary users this may be redundant, but for enthusiasts it is an indispensable tool.
Using third-party software has its advantages. These apps often present information in a more structured way than a standard menu. In addition, they can show the real screen resolution, which is sometimes changed programmatically by manufacturers, and the exact processor frequency at the current moment.
☑️ Selecting an application to check
You should remember that such applications do not require superuser rights (Root). They read publicly available system information. However, some functions may not be available on devices with heavily modified firmware from Chinese manufacturers.
Deciphering build numbers and security patches
Simply knowing the version number Android (for example, 12 or 13) is often not enough. In technical documentation and forums you can find more complex designations, such as “SP1A.210812.016”. Understanding the structure of these codes helps determine the relevance of the device.
The Build Number usually consists of several parts. The first part is the platform or device code. The second part often indicates the date or period of the firmware release. For example, in the code SP1A a letter S can denote the year (S=2021, T=2022), and P the quarter. This allows you to understand how old the firmware is, even without knowing the exact release date.
The “Google security patch level” deserves special attention. This is the date until which all vulnerability fixes known at that time are included. Even if the version Android doesn't change (for example, you don't move from 11 to 12), the patch level should be updated regularly. This is critical to protecting personal data.
If your phone shows a security patch level that is older than 6 months, this is a red flag. Manufacturers are required to release security updates regularly. Lack of recent patches makes the device vulnerable to new viruses and exploits, even if basic functions work properly.
Critical: The security patch level must be updated regularly, regardless of the release of new versions of Android. An outdated security patch is the main hole in the protection of your smartphone.Regularly updating the security patch level is more important for data protection than switching to a new major version of Android.
Frequently asked questions (FAQ)
Why did the Android version not change after the update?
Often updates come not as a change in OS version (for example, from 11 to 12), but as bug fixes and security packages. In this case, the major version remains the same, but the build number and security patch date change. This is a normal situation that ensures stable operation.
Is it possible to artificially change the Android version in the settings?
You cannot change the version in the standard menu. There is a developer mode where you can emulate another version to test applications, but this does not change the actual firmware. To actually update, you need to receive an official OTA update or manually flash it.
What does it mean if my phone stops receiving updates?
This means that the manufacturer has stopped technical support for this model. This usually happens 2-4 years after the device is released. You can continue to use such a phone, but you should be careful when installing new applications and visiting sites.
Does the Android version affect the speed of the phone?
New versions Android are often better optimized, but may require more powerful hardware. On older devices, installing a new version of the OS through unofficial channels can, on the contrary, reduce performance due to increased system requirements.
Where can I see which applications will stop working on my version?
Information about compatibility is usually provided by the store itself Google Play. If an app is not compatible with your version of OS, it will either not appear in search or will be marked as "Not compatible with your device." Developers indicate the minimum required API version in the application description.
