How to find out which Android is installed on my phone

In the modern world of mobile technologies, knowledge The exact version of the operating system is key to understanding the capabilities of your device. Users are often faced with a situation where they need to check the compatibility of a new application or find out whether the latest security features are available for their gadget. Android version determines not only the appearance of the interface, but also the deep algorithms of the processor and memory management.

Smartphone manufacturers often hide this information behind their proprietary shells, such as as MIUI, One UI or ColorOS. This can be confusing even for an experienced owner who is used to a standard interface. However, there are universal methods that allow you to obtain comprehensive information about the software in a matter of seconds, regardless of the brand of your device.

In this article we will analyze in detail all existing methods of system identification: from standard settings menus to the use of engineering codes and connection to a computer. You will learn to distinguish between the build number and kernel version, and also understand why this data is critical for the stable operation of your smartphone.

Standard method through the settings menu

The most obvious and safe way to find out information about the system lies on the surface, in the device settings section. The interface may differ slightly depending on the manufacturer, but the logic of the location of items remains the same for the entire ecosystem. You need to open the application Settings and scroll the list to the very bottom.

In most cases, the information you are looking for is in the About the phone or Phone informationsection. Inside this menu you should look for the item Android version. Clicking on this item sometimes launches the famous “Easter egg” - an animated screensaver corresponding to the system version, which confirms the authenticity of the firmware.

⚠️ Attention: On smartphones with heavy shells (for example, old versions MIUI or EMUI) Android version may be hidden inside the item MIUI Version or Build number. To see the clean version of the kernel, sometimes you need to quickly click 5-7 times on the build number, activating the developer mode, although more often it is enough to simply expand the drop-down list.

If you do not find the information right away, try using search inside the settings. Enter the word “Android” or “Version” into the search bar, and the system will redirect you to the desired screen. This method works on 99% of devices, including budget models of Chinese brands and flagships of the global market.

Using engineering codes and USSD commands

For those who prefer speed and do not want to wander through the menu, there is a method for entering special service codes. This method allows you to instantly call up a hidden service menu, which displays detailed technical information, including the security patch date. build number and the security patch date.

Open the application (dialer) and enter one of the following combinations. Please note that dialing should be done in dialing mode, and not in searching for contacts. Phone (dialer) and enter one of the following combinations. Please note that dialing must be done in the dialing mode, and not in the contact search.

• 📞 ##4636## —a universal code for entering the testing menu, where the software version is indicated in the “Phone Information” tab.
• 📞 *#1234# —often used on devices Samsung and Meizu to view the AP, CP and CSC version.
• 📞 ##7780## — reset code (use with caution!), but often shows the current firmware version before confirmation.
• 📞 #0# — general hardware testing menu, available on many pure Android devices.

It is worth noting that on modern versions of Android, manufacturers are increasingly blocking access to these codes from standard dialers for security reasons. If the code does not work and the dialing is simply reset, this means that the manufacturer has disabled this function at the firmware level.

What to do if the codes do not work?

If standard USSD codes do not open the menu, try installing a third-party application like “QuickShortcutMaker” from the Play Market store. It allows you to forcefully launch hidden system activities, including service menus that were blocked by the manufacturer.

Checking through applications and utilities

When the built-in tools do not provide a complete answer or the interface is too confusing, specialized utilities come to the rescue. These applications scan system files and display information in a convenient, structured form, often providing data that is hidden from the average user.

One ​​of the most popular tools is the application CPU-Z or AIDA64. After installing and launching the app, go to the Device or Systemtab. Here you will see not only the version Android SDK, but also information about the processor, sensors and amount of RAM.

Application	Main function	Data accuracy	Presence of advertising
CPU-Z	Hardware and OS analysis	High	Minimum
AIDA64	Full system audit	Maximum	Yes
DevCheck	Real-time monitoring	High	Absent
Device Info HW	Camera and codec details	Medium	Yes

Using third-party software is especially useful if you bought a used phone and want to make sure that the seller has not upgraded the device to an older version or a fake build. Applications show the real API Levelwhich cannot be replaced by simply replacing icons in the menu.

Identification through connection to a PC

For advanced users involved in modding or debugging devices, the most reliable source of information is connecting a smartphone to computer. This method requires enabling USB debugging mode, but provides access to the deepest layers of the system.

You must first activate developer mode. Go to Settings → About phone and click 7 times on the item Build number. After the notification “You have become a developer” appears, go to the new section of the menu and turn on the toggle switch USB debugging.

adb shell getprop ro.build.version.release

Running this command in the command line of the computer (provided installed Android SDK Platform Tools), you will receive the exact Android version number. This method is indispensable when the phone freezes in the menu or the touch screen does not respond to touches, but the system still works.

⚠️ Attention: To work with ADB (Android Debug Bridge), the appropriate drivers for your phone model must be installed on your computer. Without them, the computer will not see the device in debug mode, and the command will not be executed.

Differences between the kernel version and the build number

Frequent confusion arises among users when they see different numbers in different sections of the menu. It is important to understand the difference between the version of the operating system itself (Android Version) and the firmware build number (Build Number).

An Android version (for example, 12, 13, 14) indicates the global release of the platform from Google. It determines the available set of functions, new APIs for developers and general changes in the interface. This is what is usually meant when saying “which Android costs."

The build number is the internal marking of a specific firmware from the manufacturer. It includes not only the kernel version, but also the compilation date, distribution region and security patch number. Two phones with the same Android 13 can have completely different build numbers, if one is released for Europe and the other for China.

Why it is important to know the exact version of the system

Knowing the exact version of the software is necessary not only out of curiosity. Many modern applications have strict requirements for the minimum version. SDKIf your phone is running on an outdated version, you simply will not be able to install a banking application or a new game from the store.

In addition, security protocols depend on the system version. Old versions of Android may contain vulnerabilities that are already fixed in new updates. Regular checking allows you to understand whether your device receives support from the manufacturer or whether it’s time to think about replacing the gadget.

This information is also critical when finding solutions to problems. On tech support forums you will always be asked, “What version of Android are you on?” The answer “last” will not help the specialist, but the exact number will allow him to give specific instructions on how to fix the bug.

Is it possible to change the Android version manually?

Yes, this is possible through the flashing procedure. However, this process requires unlocking the bootloader, installing a custom recovery, and carries the risk of turning the phone into a brick. You can officially update the version only through the update menu in the settings.

Why is the build number different from the version on the manufacturer's website?

Usually this is due to a delay in the release of updates (OTA). The firmware may be released by the manufacturer, but not yet reach your device due to regional restrictions or phased distribution.

Does the Android version affect the speed?

Yes, new versions are often better optimized, but on older devices they may run slower due to increased hardware requirements. Sometimes rolling back to an older version (downgrade) can speed up your smartphone.

How do I know if my phone supports the new version of Android?

Go to Settings → System → System update and click “Check for updates”. If your phone reports that you are using the latest available version, it means that the official update for your model is no longer available.

What is Android Go Edition?

This is a lightweight version of the operating system designed for budget smartphones with a small amount of RAM (up to 2 GB). It has a simplified interface and optimized applications.
