How to find out what version of Android you have

The question of how to accurately determine the current version of the operating system often arises among users who want to update the firmware or check compatibility with new applications. Modern smartphones from Samsung, Xiaomi and other manufacturers have their own shells that can hide real information about the system core under a layer of customization. This creates confusion when the settings indicate one number, but the functionality corresponds to another.

Knowing the exact build number Android is critically important when installing drivers, obtaining root access, or diagnosing system errors. It's not always enough to just look at the "About phone" menu, since some brands, such as OnePlus or Realme, may use specific data display formats. In this article, we will look at all possible methods - from simple clicks in the interface to the use of advanced development tools.

Sometimes manufacturers deliberately delay the release of updates, and the user needs to make sure that his device is actually running on the latest available version. Or, on the contrary, you were sold a used device, and you want to check the honesty of the seller. Regardless of the reason, there are reliable ways to get this information without the risk of damaging the device.

Standard path through system settings

The most obvious and safe way to get information about the system is to use the standard settings menu. However, the path to the treasured numbers may differ depending on the manufacturer of your gadget. In “pure” Android, which can be found on smartphones Google Pixel or Motorola, the path is as short and intuitive as possible.

You need to go to the section Settings, scroll the list to the very bottom and select the item About phone or System. In some versions of the interface, information about the OS version is displayed on the main screen of this section. If you do not see the number right away, look for the subsection Software information or Version Android.

The situation becomes more complicated if you own a device with a heavy shell. For example, in smartphones Xiaomi with shell MIUI or HyperOS the Android version number is often hidden deep in the menu. There you need to click on MIUI version several times to see the hidden information. A similar logic works in devices Samsung with a shell One UI.

Please note that the settings menu displays not only the major version (for example, 13 or 14), but also the security level. This parameter Security Patch Level shows how up-to-date your device's protection against vulnerabilities is. Regular updating of this level is more important than switching to a new major version.

Features of interfaces from different manufacturers

The variety of Android smartphones on the market leads to the fact that there is no single standard for menu layout. Chinese brands often modify system apps beyond recognition to create a unique user experience. This can confuse even an experienced user accustomed to the stock interface.

• 📱 Samsung (One UI): Settings → Phone information → Software information → Android version.
• 📱 Xiaomi / Redmi / POCO (MIUI/HyperOS): Settings → About phone → MIUI version (click to expand).
• 📱 Realme / OPPO (ColorOS): Settings → About phone → Software version.

Owners of devices from Huawei and Honor may also encounter nuances. In the shell EMUI or MagicOS information is usually located in the subsection Status inside the "About phone" menu. It is important to understand that the version number of the shell (for example, EMUI 12) does not always match the version of the Android kernel (for example, Android 10), which often causes misunderstandings.

If you cannot find information in the usual way, try using the search bar inside the settings themselves. Enter the word “version” or “android”, and the system itself will highlight the desired menu item. This is a universal method that works on 99% of modern devices, regardless of brand.

Using the engineering menu and codes

For deeper diagnostics, there are special service codes that open the engineering menu. This method allows you to access technical information that is hidden from the average user in the standard interface. However, you should be careful, since changing the settings in this menu can lead to unstable operation of the phone.

To enter the service menu, open the application Phone (dialer) and enter a special combination of characters. The most common code for checking software information is ##4636##. After entering the last characters, the menu should open automatically, without the need to press the call button.

⚠️ Attention: Do not change the parameters in the engineering menu if you do not know exactly what they are responsible for. Resetting the radio module settings or changing the preferred network type may result in loss of signal or inability to make calls.

In the menu that opens, select Information about the phone (Phone Information). Here you will see detailed information not only about the Android version, but also battery status, usage statistics and network data. This method is especially useful if the standard settings menu freezes or does not work correctly.

What to do if the code does not work?

On many modern smartphones, especially from Chinese manufacturers, access to the engineering menu through codes is blocked at the firmware level. In this case, try brand-specific codes, for example #808# for OPPO or #558# for some Xiaomi models, but they are not guaranteed to work.

It is worth noting that on devices with a locked bootloader or specific regional firmware, these codes may be disabled by the manufacturer. In such cases, the system will simply ignore the input or display an error message. Then you will have to resort to other verification methods.

Checking through applications and third-party software

If the built-in system tools do not provide a complete picture or the interface is too confusing, specialized applications from the store come to the rescue. Google Play. These utilities read system files directly and display information in a convenient structured form. They often show data that is hidden even in the engineering menu.

One ​​of the most popular and reliable tools is the application CPU-Z. It displays not only the operating system version, but also detailed characteristics of the processor, sensors and battery. The tab System contains a line Android Versionthat shows the current figure. The application has similar functionality AIDA64.

The advantage of using third-party software is the detail. You will be able to see not just “Android 13”, but the full build number (Build Number), firmware compilation date and API level. This information is indispensable when searching for compatible versions of applications or mods.

Application	Size	Main function	Presence of advertising
CPU-Z	~5 MB	Detailed information about hardware and OS	Minimum
AIDA64	~8 MB	Comprehensive diagnostics of all sensors	Available in the free version
Device Info HW	~3 MB	Information about cameras and codecs	None

Installing such applications is safe if you download them from the official store. They do not require root access for basic diagnostics and do not make changes to the system. After receiving the necessary information, you can safely delete the application so as not to take up memory space.

Advanced method: debugging via USB and ADB

For users who are not afraid of the command line, there is the most accurate verification method - using the toolkit ADB (Android Debug Bridge). This method allows you to obtain information directly from the system properties of the device, bypassing the graphical interface. It is often used by developers and advanced enthusiasts.

First, you need to enable the mode For developers in your phone settings. This is usually done by clicking seven times on Build number in the "About phone" menu. Then in the new menu that appears, you need to activate the switch USB debugging.

adb shell getprop ro.build.version.release

Once you have connected your phone to your computer and installed the ADB drivers, you can enter the command above in the terminal or command line of your PC. It will instantly return the Android version number. There is also a command adb shell getprop ro.build.version.sdkthat will show the digital code of the API version.

⚠️ Attention: When connecting your phone to an unfamiliar computer in debugging mode, be careful. A debugging permission request will appear on the device screen with the RSA key fingerprint. Confirm the connection only on trusted PCs to avoid data theft.

This method is universal and works even on devices with a broken screen, if the sensor is partially functioning or the mouse is connected via OTG. It also allows you to check the Android version on devices that do not boot into graphical mode, but are accessible through recovery mode with ADB support.

Version and codename correspondence table

The history of the development of Google's mobile operating system includes more than a dozen major updates. Each version was given a code name after the sweets, although in recent versions Google has moved away from this tradition in public marketing, leaving internal names. Knowing this table will help you understand how modern your device is.

Below is a table linking the version number, common name and API level. The API level is important for application developers, as it determines the availability of certain programming functions.

Android version	Code name	API level	Release year
Android 14	Upside Down Cake	34	2023
Android 13	Tiramisu	33	2022
Android 12	Snow Cone	31-32	2021
Android 11	Red Velvet Cake	30	2020
Android 10	Quince Tart	29	2019

Devices with versions lower Android 10 is considered obsolete. Many popular applications, such as new versions of banking clients or instant messengers, are gradually discontinuing support for older versions of the system. If your smartphone is stuck on Android 8 or 9, you should think about replacing it or installing custom firmware.

Frequently asked questions and problems determining the version

Users often encounter a situation where the phone shows one version, but applications require another, or the number does not change after the update. This may be due to the peculiarities of OTA updates, when the system is updated in parts, or because the manufacturer did not update the version line in the interface.

Why did the Android version not change after the update?

Perhaps a Security Patch has arrived, rather than a major system update. Also, on some devices with custom skins, the Android version number is updated with a delay relative to the release of the patch. Check the Build Number - it should change.

Is it possible to find out the Android version if the phone does not turn on?

If the phone does not boot into the system, but the screen turns on, try going into Recovery mode (usually the power button + volume up). Some recovery menus display the system version at the top or bottom of the screen. You can also try connecting your phone to a PC in ADB mode, if the bootloader allows it.

Does the Android version affect the speed of the smartphone?

Yes, new versions of Android are optimized for modern hardware, but on older devices they may work slower due to increased resource requirements. However, new versions contain important security fixes and memory management improvements, which are more useful in the long run.

What is a "security patch level" and why do you need it?

This is the date by which vulnerabilities in the system are patched. Even if you have an older version of Android (for example, 11), regularly updating your security level protects you from new viruses and exploits. This is a critical parameter that you need to pay attention to.

How to check if the Android version is official?

Compare the build number in the settings with the number on the manufacturer's official website for your model and region. If the numbers do not match or there are suspicious characters in the version, the device may have custom or modified firmware installed.

In conclusion, it is worth noting that regularly checking the system version is a good habit for any smartphone owner. It allows you to keep abreast of technological updates and ensure maximum security for your personal data. Do not ignore update notifications that appear in the status bar.
