Users are often faced with the need to accurately determine which operating system is installed on their device. This may be required when installing specific applications, diagnosing errors, or before selling the gadget. Equipment owners Samsung should take into account that the interface One UI visually hides some technical details, making the verification process a little more confusing than on a pure one. Android.
There are several reliable ways to get comprehensive information about the firmware. We will look at standard methods through the settings menu, using hidden engineering codes and checking through a computer. Knowing the exact software build will help you avoid software incompatibility and understand whether your device has the latest security update.
Checking through the standard settings menu
The simplest and safest method is to use the built-in interface. You don't need third-party utilities or a PC connection. Just unlock the screen and find the gear icon on the main screen or in the notification shade.
After entering the menu, scroll down the list to the very end. There you will find the item Phone information. By clicking on it, you will be taken to a section with complete technical information. Please note that in new versions of the shell One UI data may be grouped differently than in older firmware.
In the window that opens, find the line Software version or Software information. This is where the necessary information is hidden. By clicking on this item, the system will reveal details, including the build number and security patch date. Sometimes you need to click on a line several times to activate hidden fields.
⚠️ Attention: Do not repeatedly click on the "Build number" item if you do not plan to enable developer mode. This action activates USB debugging, which can change the behavior of some system functions.
For clarity, let's look at the differences in data display on different versions of the interface. Below is a table showing exactly where to look for information depending on the year of manufacture of the device.
| One UI version | Path to information | Android version location |
|---|---|---|
| One UI 6.x | Settings → Phone information → Phone information Software | Second line in the list |
| One UI 5.x | Settings → Phone information → Software information | Second line in the list |
| One UI 4.x | Settings → Phone information | Immediately below the device model |
| One UI 3.x and older | Settings → Phone information → Software information | Inside a submenu |
In modern versions of One UI, the Android version number is often hidden inside submenu "Software information", and is not displayed on the main screen of the "About phone" section.
Using the engineering menu and USSD codes
If the standard menu is for some reason not available or you want to get more detailed technical data, you can use special codes. This method works on most smartphones Samsung without obtaining root access.
Open the Phone application and go to the dialing tab. Enter the combination *#1234#. Immediately after entering the last hash mark, the service menu should appear on the screen. Here you will see three key parameters: AP, CP and CSC.
- 📱 AP (PDA) —shows the main firmware version and the Android kernel version.
- 📡 CP (PHONE) —displays the version of the modem and the basic software of the radio module.
- 🌍 CSC —indicates the sales region and telecom operator settings.
The AP line usually The Android version is indicated in a format understandable to technical specialists. For example, the code may contain numbers indicating a major version of the system. This is especially useful if the system interface has been customized or modified by third-party themes.
What to do if the code does not work?
Some telecom operators block access to the engineering menu on locked devices. In this case, try the code #0# to check the hardware or use third-party applications from Google Play.
There is also a code *#1234#that is universal for checking the software version. However, on some new models with enhanced security Knox this functionality may be limited. In this case, the system simply will not respond to the input or will prompt you to go to the standard settings menu.
Analyzing information through a computer and ADB
For advanced users who need maximum accuracy, the ideal option would be to connect a smartphone to a PC. This method allows you to extract raw data from system files that are not displayed in the GUI.
You will need to install drivers Samsung USB Driver and utility ADB (Android Debug Bridge). After enabling USB debugging in the developer menu, connect your phone to the computer with a cable. Open a command prompt or terminal in your ADB tools folder.
adb shell getprop ro.build.version.releaseThis command will display the exact Android version number, such as "13" or "14". To get the build number, use the following command:
adb shell getprop ro.build.display.idThis approach eliminates any visual distortion from the shell One UI. You get data directly from system properties build.prop. This is an indispensable tool when flashing a device or rolling back to a previous software version.
⚠️ Attention: To work with ADB, you must enable “USB Debugging” in the developer menu. Do not connect your phone to unfamiliar computers with debugging enabled, as this gives full access to the file system.
☑️ Preparing for testing via PC
Third-party diagnostic applications
If you don't want to bother with codes or cables, the store Google Play offers many utilities for monitoring the system. They provide information in a convenient, structured form, often with graphs and additional hardware data.
One of the most popular solutions is the application Device Info HW or AIDA64. After installation and launch, the app automatically scans the device. You need to go to the “System” or “OS” tab, where not only the Android version number will be indicated, but also the security patch level.
The advantage of such applications is the ability to copy data to the clipboard with one click. This is convenient if you need to send information to support or save it for a report. In addition, they show actual RAM usage and battery status.
When installing diagnostic applications, pay attention to permissions. A good utility does not need access to contacts or a microphone to determine the system version.
Some users prefer to use CPU-Z. Although this application is CPU-centric, the System tab clearly displays the kernel and build version. This is especially true for owners of older models Samsung Galaxywhere the standard menu may be unstable.
Decoding the build number and security patches
Just knowing the Android version number is not enough. It is important to understand the structure of the build number as it contains information about the firmware release date and region. The build number usually looks like a series of letters and numbers, for example S918BXXU5AWL1.
The last four characters often indicate the date the firmware was created. The first letter represents the year (A=2019, B=2020, C=2021, etc.), the second letter represents the month (A=January, B=February... L=December, excluding I), and the last two digits represent the day of the month. Knowing this algorithm, you can determine how recent your system is.
The level of the security patch is also critically important. It shows when the system's vulnerability databases were last updated. You can find it in the same menu Software information. Regularly receiving patches is more important than a major update to the Android version.
The date in the build number allows you to accurately determine the age of the firmware, even if it is not in the settings the release date of the update is indicated.
Possible problems and solutions
Sometimes users are faced with a situation where the software version is not displayed or is displayed incorrectly. This may be due to a launcher malfunction, unsuccessful update, or installation of a custom recovery.
If the settings menu freezes when you try to open the "About phone" section, try clearing the cache of the "Settings" application. To do this, go to Settings → Applications → Settings → Storage → Clear cache. This action is safe and will not delete your personal data.
- 🔄 Restart your device in safe mode to eliminate the influence of third-party applications.
- 🗑️ Clear the cache partition through the Recovery menu (turn off the phone, hold Volume Up + Power).
- 📥 Try manually checking for updates via Wi-Fi.
In rare cases, especially on devices purchased on the secondary market, system information may be changed. Fraudsters sometimes change data in configuration files to pass off an old model as a new one. Checking through a computer using ADB or specialized utilities like SamFw Tool will help uncover the deception.
⚠️ Attention: If you bought the phone secondhand and the software version does not match the declared model or region, check the device through the Samsung Members service. A mismatch of the CSC region can lead to problems with the operation of contactless payment and updates.
Since update policies and interfaces may change with the release of new versions of One UI, it is recommended to periodically check the current menu paths with the official manuals on the manufacturer’s website. Details of the location of the items may vary slightly depending on the regional firmware.
