In today's world of mobile technology, knowing the exact version of the operating system is a key factor in ensuring application security and compatibility. Many users are faced with a situation where new software requires a certain build, and old games no longer run on outdated kernels. Understanding exactly what modification Android is installed on your device helps you make informed decisions about purchasing new gadgets or the need to replace your current device.
Determining the current build of the operating system is not difficult, but the path to this information may vary depending on the manufacturer and the installed shell. Device owners Samsung, Xiaomi or Google Pixel will see slightly different menus, although the navigation logic remains the same for the entire ecosystem. We will analyze all possible ways to obtain this data, from standard settings to using the engineering menu for advanced users.
In addition to the version number, it is critically important to pay attention to the date of the last security update, since this parameter indicates the relevance of security patches. It often happens that the major version number remains the same, for example, Android 13, but the security build number changes monthly, closing vulnerabilities. Ignoring this aspect may put your personal data at risk, so the check must be comprehensive.
Standard method through system settings
The most universal and safe way to get the necessary information lies on the surface of the interface of your smartphone. You will need to open the main application menu and find the gear icon that represents the section Settings. In most modern shells, this item is fixed at the top of the list or placed in the quick notification panel when you swipe down.
After entering the menu, you need to scroll down the list to the very end, where the section About phone or About phoneis usually located. In some custom firmware, such as MIUI from Xiaomi or ColorOS from Oppo, this information may be hidden inside a subsection About device or Software information. By clicking on this item, you will see a brief summary of the characteristics of your gadget.
⚠️ Attention: In budget models of some Chinese brands, the “Android Version” item may be hidden inside the menu "Special Features" or require an additional entry into the "Software Information" submenu to unlock full information.
In the window that opens, find the line labeled as Android version. The number next to it (for example, 12, 13 or 14) is the major version of your system. Often next to it is indicated a more detailed build number, consisting of letters and numbers, which is necessary for technical support specialists to accurately identify the firmware.
If the “About phone” item does not contain the Android version, try clicking on the “Build number” item several times in a row - sometimes this will activate a hidden developer menu with extended information.
Features of interfaces from different manufacturers
Smartphone manufacturers strive to make their products unique by overlaying their own graphic shells on top of a clean one. This leads to the fact that the path to the treasured information may differ significantly from the stock version adopted in the devices of the line Android own graphical shells. This leads to the fact that the path to the treasured information may differ significantly from the stock version adopted in the devices of the line Google Pixel. Understanding these differences will save you time when searching for the options you need.
Let's look at the main differences in navigation for popular brands so you can quickly navigate the menu:
- 📱 Samsung One UI: Go to
Settings, scroll to the bottom and select Phone information, then clickSoftware information. - 🤖 Xiaomi MIUI / HyperOS: Open
Settings, select the topmost item About phone, the version will be indicated in large font under the logo. - ⚡ Realme UI: Go to
Settings, scroll down to the section About device, the information is at the top of the screen. - 🔵 Google Pixel (Stock Android): Menu
Settings→ System →System updateor section About phone at the bottom of the list.
It is worth noting that in the shell One UI from the company Samsung developers often group technical data into separate subcategories to improve user perception. This means that simply entering “About phone” may not be enough, and one extra click will be required to reveal the full picture.
Owners of devices from Huawei and Honor should be careful, since after the separation of brands, the menu structure in the new models has undergone changes. If you cannot find information in the standard way, use the built-in search for settings by entering the query “version” in the search bar at the top of the settings screen.
Using engineering menu codes
For advanced users who find standard menus insufficiently informative, there is access to hidden service sections through a set of special USSD commands. This method allows you to access technical data that is usually hidden from the eyes of the average user, including detailed information about the radio module and the version of the basic software.
To use this method, open the application Phone (dialer) and enter one of the following combinations of numbers and symbols. After entering the last character, the menu should open automatically, without the need to press the call button:
##4636##This command is universal for most devices based on chipsets Qualcomm and MediaTek. It opens the testing menu, where in the tab Phone information you can find not only the Android version, but also the network status, signal strength and battery data. However, on some devices, especially from Samsung or Meizu, this code may be blocked by the manufacturer.
⚠️ Attention: Do not change the settings in the engineering menu if you are not sure of your actions. Accidentally changing the preferred network type or resetting usage statistics can lead to unstable communication.
Alternate code *#1234# is often used in devices Samsung to display the AP, CP and CSC versions, where the AP is responsible for the main Android system. If none of the codes work, it means that the manufacturer has limited access to this functionality for security reasons, and you should use third-party software.
What to do if the code does not work?
If entering the code does not bring up a menu, try installing the Activity Launcher application from the Play Market. It allows you to launch hidden system activities, including the standard testing menu, even if the USSD code is blocked.
Checking through third-party applications
When the built-in system tools for some reason do not provide a complete picture or the interface is too confusing, specialized utilities from the store come to the rescue. Google Play. These applications scan hardware and software, providing a comprehensive report in an easy to read format.
One of the most popular and reliable tools is the application CPU-Z or AIDA64. After installation and launch, the app automatically collects data about the processor, sensors, battery and, of course, the operating system. The System or OS tab will show not only the Android version, but also the API level, which is important for developers and advanced users.
The advantage of using such utilities is the ability to save a report or take a screenshot with the full technical specifications of the device. This is especially useful when selling a smartphone, since the buyer can verify the authenticity of the declared characteristics and the absence of modified software.
| Application name | Size | Main function | Presence of advertising |
|---|---|---|---|
| CPU-Z | ~5 MB | Information about the processor and OS | Minimum |
| AIDA64 | ~10 MB | Full diagnostics of all sensors | None |
| Device Info HW | ~3 MB | Details of cameras and codecs | Yes |
| DevCheck | ~8 MB | Real-time monitoring | In the free version |
It is important to download such utilities only from the official store Google Playto avoid installing malware that can masquerade as system tools. Trusted developers guarantee the security of data and the correctness of the information displayed.
Third-party applications often show the real version of the Linux kernel on which Android is based, which allows you to identify a counterfeit device if the declared version of the system does not match the kernel.
Deciphering build numbers and security updates
The numbers you you see in the settings, this is not just a random set of characters, but encrypted information about the release date and the level of stability of the firmware. Understanding this marking is useful for understanding how recent the software is installed on your gadget and what functions it may be missing.
Usually the build number looks like a sequence of letters and numbers, for example, SP1A.210812.016. The first letter indicates the Android version code (S - Android 12, T - Android 13, U - Android 14). The following symbols often indicate the quarter and year of release of this version of the platform by developers Google.
Separately, it is worth mentioning the security patch, which is usually indicated in the format YYYY-MM-DD (Year-Month-Day). If the patch date is older than six months, this is a signal that your device is vulnerable to known exploits and you need to check for updates manually. The regularity of these patches depends on the manufacturer's policy and device model.
Sometimes users are faced with a situation where the Android version number does not change for years, although security patches arrive regularly. This is typical for the budget segment, where manufacturers limit themselves to supporting one major version of the system, providing only critical fixes for vulnerabilities.
What to do if the version is outdated
If a check shows that your device has a version installed whose support has been discontinued, a natural question arises about further actions. Outdated software may cause incompatibility with new versions of popular instant messengers, banking applications and services, which significantly limits the functionality of the smartphone.
The first step should always be an attempt to update the system using standard means. To do this, go to the Settings → System → Software update section and click the check button. If an update is available, the system will prompt you to download and install a new package, which usually takes from 15 to 40 minutes depending on the Internet speed and data volume.
☑️ Preparing for the update systems
In case the official update is not available, advanced users may consider installing custom firmware such as LineageOS or Pixel Experience. This process requires unlocking the bootloader and installing a custom recovery, which carries the risk of losing the warranty and possible failure of the device due to errors.
⚠️ Attention: Installing unofficial firmware will void the manufacturer's warranty and may lead to inoperability of banking applications due to the triggering of SafetyNet or Play Integrity protection mechanisms.
If the device is physically unable to support new versions of Android due to a weak processor or small amount of RAM, the only option is to replace the smartphone with a more modern model. Attempts to force the installation of heavy systems on old hardware will only lead to slowdowns and rapid battery drain.
Frequently asked questions (FAQ)
Is it possible to find out the version of Android if the phone does not turn on?
If the device does not boot to the desktop, it is impossible to find out the version using software methods. The only option is to look at the information on the original box of the smartphone or under the battery (if it is removable), where the serial model number is often indicated. By this number you can find the specifications on the manufacturer's website.
Why has the Android version not changed after the update?
Manufacturers often release intermediate updates that contain only bug fixes and security patches, without changing the major version of the system. It is also possible that you only updated the manufacturer's skin (for example, MIUI or One UI), while the base version of Android remained the same.
Does the Android version affect the speed of the phone?
Yes, new versions of the system are usually better optimized and run faster on modern hardware, but may be more difficult for older devices. Switching to a too new version of Android on an old smartphone can, on the contrary, reduce performance due to increased requirements for processor and memory resources.
How do I know if my phone supports the new version of Android?
Official information about support can only be found on the manufacturer’s website in the specifications section of your model. Third-party resources may offer the possibility of updating, but only the device vendor provides a guarantee of compatibility.
Is it dangerous to use a phone with a very old version of Android?
Using devices with a version lower than Android 8.0 becomes risky, since many security certificates are outdated, and new applications no longer support them. This makes the device vulnerable to network attacks and does not allow you to use the latest versions of banking clients.
