In the modern world of mobile technology, it is not enough to simply call a smartphone “Android”. The platform is developing rapidly, and operating system version directly affects security, speed and compatibility with new applications. Users often confuse the device brand name with the software version, which leads to errors when installing apps or attempting repairs.
Knowing the exact modification of your gadget is necessary not only for updating the firmware, but also for selling used equipment, receiving technical support or selecting accessories. Google and device manufacturers are constantly changing interfaces menu, so there is no universal path to information, but there are proven methods that work on 99% of devices.
In this article we will look in detail at how to get comprehensive information about your device using the built-in system tools, special codes and connecting to a computer. You will learn to distinguish Android 13 from Android 14 and understand what is hidden behind the model marking.
Checking the version through the settings menu
The most reliable and safe way to find out the current software version is through the standard settings menu. Despite the differences in shells from Samsung, Xiaomi or Honor, the search logic remains similar. You need to find the section responsible for general information about the phone.
In pure Android (used in Pixel, Motorola, Nokia smartphones) the path is as short as possible. Just open the Settings application, scroll to the bottom of the list and select About the phone or System. A large number of the Android version will immediately be indicated there.
In custom shells the situation is a little more complicated due to marketing renamings. For example, in MIUI from Xiaomi the information is hidden deeper. You will need to go to the About phonesection, and then click on the line MIUI version several times to see the basic version Android.
Sometimes manufacturers hide detailed information behind additional menus. If you do not see the version right away, look for subsection Software information or Device information. It usually lists the build number, security patch level and kernel version.
⚠️ Attention: Manufacturer interfaces are updated regularly. If you cannot find the item you need by description, use the search bar at the very top of the settings menu by entering the request “About phone” or “Version”.
Using service codes and engineering menu
For deeper diagnostics, which is not always available in the regular menu, there are secret USSD codes and engineering menu commands. This method allows you to obtain technical information directly from the modem and system, bypassing the graphical shell.
To use this method, open the “Phone” application (dialer) and enter a special combination of characters. For most chip-based devices MediaTek or Qualcomm the code ##4636##works. After entering the last characters, the menu will open automatically, without the need to press the call button.
In the list that opens, select the item Phone information. Here you will see not only the Android version, but also IMEI, network status, battery type and detailed signal information. This is especially useful if the touch screen does not work correctly and you cannot enter the usual settings.
It is worth remembering that many manufacturers, such as Samsung or Huawei, block access to the standard engineering menu in the latest firmware versions. In such cases, the code may simply not work or display an error message.
Do codes work on locked phones?
Yes, most service codes, including ##4636##work even on the lock screen if you have access to dial (emergency call). However, on some new models with enhanced security, this access may be denied until the device is unlocked.
Determining the model and characteristics of the device
Knowing the version of the operating system is important, but to purchase a case, glass or spare parts, it is critical to know the exact one. device model. A marketing name (for example, “Galaxy S21”) often combines several different modifications with different processors and network support.
In the same menu About the phonethat we talked about earlier, be sure to find the line Device model or Model number. It looks like a set of letters and numbers, for example SM-G991B or M2101K7BG. It is this code that should be used when searching for compatible accessories.
Information about the processor (SoC) and the amount of RAM is also indicated here. This data helps to understand the potential of the smartphone. If the specifications indicate 4 GB of RAM, then launching heavy games at maximum settings may be difficult, regardless of the Android version.
To get the most complete technical map of the device, you can use third-party utilities, such as CPU-Z or AIDA64. They show core frequency, screen matrix type, battery capacity in mAh and component temperatures in real time.
When searching for parts, always use the full model code (for example, SM-A525F), not the commercial name. Different regions of release of the same model may have incompatible charging connectors or cameras.
Viewing information through a connection to a PC
If the smartphone screen is broken or the system is unstable, you can find out the characteristics through a connection to a computer. This method requires installing drivers, but provides access to system logs and accurate data about the hardware.
Connect the phone to the PC via a USB cable. In file transfer mode (MTP), you can simply view the device properties in “My Computer,” but only basic information is displayed there. For detailed diagnostics, it is better to use developer tools.
If USB debuggingis enabled on your phone, you can use the app ADB (Android Debug Bridge). By entering the command in the computer terminal, you will receive a complete list of installed packages and the system version in text form, which is convenient for copying.
There are also universal apps for managing mobile devices, such as AirDroid (works over Wi-Fi) or proprietary utilities from manufacturers (Samsung Smart Switch, Mi PC Suite). They automatically detect the model, firmware version and warranty status when connected.
adb shell getprop ro.build.version.releaseThis command will only display the Android version number, which is convenient for scripts or quick checks without unnecessary information. It works on most devices with developer rights.
| Verification method | Difficulty | Access required | Authority |
|---|---|---|---|
| Settings menu | Low | No | High |
| Service code | Medium | No | High |
| Applications (CPU-Z) | Low | Internet | Very high |
| Computer (ADB) | High | PC + Cable | Maximum |
How to find the Android version on tablets and TV set-top boxes
Owners of tablets and Android TV boxes often encounter difficulties, since the interface of these devices is very cut down The principle of searching for information is the same, but navigation may differ due to the remote control or the lack of familiar icons.
On TVs with Android TV or Google TV go to the settings (gear), then select System or About the device. The build number and OS version will be indicated there. For remotes without menu buttons, you may need to long press the Home key.
On tablets, the path is similar to smartphones: Settings → About tablet. However, on some Chinese models without a certificate Google the menu may be entirely in Chinese. In this case, focus on the gear icon and the “i” symbol in a circle.
If the interface is not navigable, you can try installing an application to control it from your phone. Many manufacturers allow you to broadcast the screen or manage the settings of a TV set-top box through a mobile application, where information about the system is displayed more clearly.
⚠️ Attention: On TV set-top boxes with pirated content or custom firmware, the data in the “About device” menu can be replaced. Fraudsters often change the displayed version of Android to a newer one, although the old system is installed inside.
The only way to be sure to check the real version of Android on a suspicious device is to install a benchmark (for example, AnTuTu) or a CPU-Z application that reads data directly from the system kernel, ignoring substitution in the menu.
Frequent and hidden problems nuances
Sometimes users are faced with a situation where the phone shows one version, but applications require another. This may be due to the fact that the manufacturer installed a shell based on an old version Androidbut changed the build number for marketing purposes.
There is also the problem of “gray” smartphones imported from other regions. They may have global firmware on top of the Chinese one, which causes version conflicts and the absence of some services Google. In this case, the settings menu may display incorrect data about the region.
Another nuance is that these are beta versions of the software. If you are participating in a testing app, you may have a version marked Beta or Developer Previewinstalled. Such systems may be unstable, and banks or some games may refuse to run on them.
- 📱 Always check the security patch level: even with the same version of Android (for example, 12), the 2022 patch is less secure than the 2026 patch.
- 🔄 Over-the-air (OTA) updates may not arrive on your device. custom firmware - in this case, the version can only be found through the Recovery menu.
- ⚙️ Resetting to factory settings does not change the Android version, it only returns system applications to the original state of the version that is currently installed.
Understanding these nuances will help you avoid compatibility and security problems. You should not blindly trust the inscriptions on the box or in advertising brochures, especially when buying a device from your own.
Questions and answers (FAQ)
Is it possible to find out the Android version if the phone does not turn on?
If the phone does not boot to the desktop, but the screen turns on, you can try going to mode Recovery (usually the power button + volume up). The system version is often written at the top of the menu. If the screen is black, it is impossible to find out the version without connecting to the programmer.
Why does the settings say Android 13, but the Play Market requires 14?
Most likely, your device is at the stage of receiving an update. Application developers are starting to demand new API versions in advance. Check for updates in the menu System → Software update. If there is no update, it means that the manufacturer has not yet adapted the firmware for your model.
Does the Android version affect the speed of the phone?
Yes, it does. New versions Android are optimized for modern hardware, but on older devices they may run slower due to increased resource requirements. Sometimes rolling back to an older version (downgrade) can speed up the operation of an old smartphone, but this is a complex procedure.
How do I know if my phone is supported by updates?
Go to the manufacturer’s official website, find your model by code (from the “About phone” section) and look at the support section. The period for guaranteed security updates and major OS versions is indicated there. Usually this is 2-4 years from the date of release.
What is a build number and why do you need it?
Build Number is a unique identifier of a specific firmware version. It is needed to accurately diagnose problems. If you have an error, technical support will ask for this exact number in order to understand which version of the software is installed, since within one version of Android there may be dozens of assemblies with error fixes.
