Users are often faced with the need to accurately identify their gadget, whether to search for drivers, check application compatibility, or sell used equipment. The marketing name that a manufacturer assigns to a smartphone when it goes on sale often differs from the real one embedded in the system. For example, a popular model number, hardwired into the system. For example, popular Samsung Galaxy S23 in different regions may have different letter indices, which is critical when ordering spare parts.
Not only a visual inspection of the case, but also software methods help determine the exact name. In this article we will analyze all the available methods: from simple settings to using diagnostic utilities. You will learn to find hidden information about serial number and hardware revision, which is not always on the surface of the interface.
Knowing the exact model of the device is the key to solving many technical problems. If you are planning to flash or unlock the bootloader, a mistake in one letter of the code can turn your phone into a brick. Therefore, it is important to understand the difference between a commercial name and a technical identifier.
Checking through the standard settings menu
The most obvious and safest way to get information about the device is to look in the system menu. The path may differ slightly depending on the version Android and the manufacturer's shell (MIUI, One UI, ColorOS), but the logic remains the same. Usually the data is hidden in the section responsible for general information about the system.
You need to open the “Settings” application and scroll the list to the very bottom. Look for an item called “About phone”, “About device” or “System”. The window that opens will display a large logo of the Android version and, as a rule, the model name. However, it is often the marketing name that is indicated here, and not the technical code.
To see hidden details, such as build number or the internal model code, sometimes you need to click on this item several times in a row. This action activates developer mode or simply opens an additional tab with specifications. In some shells, for example u Xiaomi, you need to tap on the MIUI version to see the full list of processor and memory characteristics.
⚠️ Attention: Do not randomly click on all the items in the “For Developers” section if you accidentally activated it. Changing the USB debugging settings or the limit of background processes can disrupt the stable operation of the system.
If only the brand is listed in the “About Phone” menu (for example, just “Samsung”), click on the line with the model name - often a full alphanumeric index is hidden there.
For clarity, we provide a table showing exactly where to look for information in popular interfaces:
| Manufacturer / Shell | Menu path | Where the model code is indicated |
|---|---|---|
| Stock Android (Pixel, Motorola) | Settings → About phone | At the very bottom of the list, item “Model” |
| Samsung (One UI) | Settings → About phone → Software information | Device model line |
| Xiaomi (MIUI/HyperOS) | Settings → About phone | Click on the "MIUI" logo several times |
| Huawei (EMUI) | Settings → System → About phone | Line “Model” or “Build number” |
Using service codes and engineering menu
If access to settings is limited or the interface is damaged, special USSD commands come to the rescue. These are hidden requests that call up the engineering menu or test mode directly through the dialing interface. This method works on most devices without the need to obtain root access.
Open the “Phone” application and enter one of the following combinations. After entering the last digit or symbol, the menu should open automatically; there is no need to press the call button. The list of commands varies from manufacturer to manufacturer:
- 📱
*#06#—a universal code for displaying the IMEI and serial number on any device. - 📱
*#1234#—often used in devices Samsung to view the firmware version and model. - 📱
##4636##—calling the Android test menu (works on many clean smartphones and Xiaomi). - 📱
#0#—expanded hardware testing menu Samsung.
In the engineering menu that opens, look for sections named “Version”, “Device Info” or “Hardware”. The exact board code and device revision will be indicated. This is especially useful if you bought the phone secondhand and want to make sure that there is an original motherboard inside, and not a refurbished version.
It is worth noting that on modern versions of Android some codes may be blocked by the telecom operator or the manufacturer itself for security reasons. If the code does not work, try entering it without asterisks or use alternative methods.
Searching for information on the case and under the battery
Physical marking remains the most reliable source of truth, especially if the device does not turn on. legislation of most countries. The location of the label depends on the design of the smartphone.
In modern monoblocks with a non-removable battery, look for small print on the back cover. Often this information is duplicated on the tray under the device. You need to find the line Model or Model No.For example, the code may look like SM-G991B or M2101K7AG.
If you have a device with a removable battery (which is now rare, but is found in rugged models or the budget segment), the information is located under it. You must carefully remove the back cover and remove the battery. The sticker inside the compartment will indicate the serial number, production date and full name of the model.
⚠️ Attention: When removing the back cover. use special suction cups or mediators. Do not use force to avoid damaging the glass or plastic latches of the case, especially if the phone is glued.
What to do if the sticker is erased?
If the factory markings are not readable, try shining a flashlight at an acute angle on the back cover. Sometimes the laser engraving remains visible even after the paint is erased. warranty card or box.
Pay attention to barcodes. Scanning a QR code from the box or back panel through the camera of another smartphone often immediately displays the full specification of the device in the search results.
Diagnostics via a computer and the ADB utility
For advanced users and tinkerers, the most accurate method is to use the Android Debug Bridge (ADBThis tool allows you to request any information from the system directly, bypassing the graphical interface. The method requires a PC and USB debugging enabled on the smartphone itself.
First you need to install the device drivers and Platform Tools on your computer. cable and enable debugging in the pop-up window on the gadget screen. Then open the command line or terminal in the folder with ADB and enter the command to get the system properties.
adb shell getprop ro.product.modelThis command will display the exact technical name of the model. If you need to find out more detailed information, for example, the name of the manufacturer or the version of the board, use the command adb shell getprop without arguments - it will display a complete list of all system ones. variables. Look for lines starting with ro.product.
☑️ Preparing for diagnostics via ADB
The advantage of this method is that it works even if the screen sensor is partially not functioning, but the system boots. You can control the device and read data completely from the computer. This is an indispensable tool for diagnostics. "bricks" with a working bootloader.
Third-party applications for identification
If the built-in tools do not seem informative enough to you, there are many utilities on Google Play that specialize in collecting telemetry. They provide data in a convenient structured form, often with photographs of similar devices and links to drivers.
One of the most popular and reliable solutions is the application CPU-Z. It shows not only the model name, but also detailed information about the processor (SoC), sensors, temperature and actual battery capacity. Another option is AIDA64, which provides a comprehensive report on all hardware components.
- 📊 CPU-Z is a lightweight application. showing the “Device” tab with the full name and code.
- 📊 AIDA64 - a professional tool for in-depth diagnostics of all subsystems.
- 📊 DevCheck - a utility with an emphasis on monitoring sensors and battery status in real time.
The use of such apps also helps to identify a fake If it is written in the phone settings Samsung Galaxy S24 Ultra, and the CPU-Z application shows an old processor MediaTek and a screen resolution of 720p, then this is a clear replica of low quality.
⚠️ Attention: Download diagnostic utilities only from the official Google Play store. Third-party sites may distribute modified versions of applications that contain spyware or viruses.
Third-party applications are the best way to distinguish an original device from a high-quality fake, as they read the real characteristics of chips that cannot be faked with software in cheap replicas.
Frequently asked questions and problems when determining the model
In progress When searching for information, users often encounter non-standard situations. For example, the device may appear in the system as a generic model after a firmware reset, or the model code may not match the region of purchase. Let's look at the main scenarios.
Sometimes after installing custom firmware (Custom ROM), the name of the firmware itself (for example, LineageOS) may be displayed in the “About phone” menu instead of the name of the smartphone. In this case, you only need to rely on service codes or data from the box, since the software shell was changed by the user.
There is also the practice of regional versions. The same phone for the US, European and Chinese markets may have different model codes due to support for different LTE frequencies or dual SIM cards. This is not a defect, but only a feature of the manufacturer’s logistics.
Why is one name written in the settings, but another on the box?
This is a normal situation. The box includes the full serial number and batch code for logistics purposes, and the settings menu often displays a shortened marketing name for user convenience. It is the digital model code that needs to be checked (for example, SM-A515F).
Is it possible to change the device name in the system?
Yes, the name that is visible on Bluetooth and Wi-Fi networks can be changed in the settings. However, the technical code of the model (ro.product.model), which is visible to the computer and applications, cannot be changed without superuser rights (Root) and editing the system build.prop file.
What to do if the phone does not turn on and you need to find out the model?
If the screen is black, the only way is physical inspection. Look for engraving on the back cover, SIM card tray (sometimes there are micro-marks there) or the original packaging. Also, the model is often indicated on the purchase receipt or in the warranty card.
Does the model code affect the receipt of updates?
Yes, critically. The update servers check for an exact match between the model code and region code (CSC). If you try to install firmware from another model (even if they are externally identical), the phone may lock or stop receiving the network.
