Sometimes a situation arises when it is urgently necessary to determine the exact model and manufacturer of a mobile device. This may be necessary when searching for drivers, selling a gadget, or buying accessories when the stickers on the case have worn off or were missing initially. For inexperienced users, the interface of modern shells may seem confusing, but device identification this is a basic task that can be solved in a couple of minutes.
There are many methods, from simple checks in the menu to the use of special engineering codes. If you purchased a smartphone secondhand or received it as a gift without a box, this article will help you understand the characteristics. We will consider both standard paths through system settings, and more advanced methods for cases when the interface is blocked or changed.
Particular attention should be paid to situations when the phone is a replica or fake. In such cases, the information on the menu may be deliberately distorted by scammers. Therefore, to obtain reliable data, it is recommended to use a combination of several verification methods described below.
Searching for information in system settings
The most obvious and safest way is to refer to the built-in configuration menu. Almost all manufacturers place data about device model in the “About Phone” section. However, the path to this section may differ depending on the version Android and installed shell (MIUI, One UI, ColorOS).
Usually you need to go to the main application menu and find the gear icon. Next, the sequence of actions is as follows:
Settings → About phone → Device model.
In some cases, for example on pure Android from Google, this information is hidden deeper:
Settings → System → About phone.
Please note that this section often indicates not only the commercial name (for example, Samsung Galaxy S21), but also the technical model code (for example, SM-G991B). It is the technical code that is the most accurate identifier for searching for spare parts or firmware. It is unique for each memory modification and regional version.
⚠️ Attention: If the name of a well-known brand is indicated in the menu, but when you go to the “Android Version” or “Build Number” section you see strange symbols or a system version older than 5 years with a modern design, there is a high probability that this is a Chinese fake.
Using engineering codes and USSD commands
If access to the settings menu is limited or you want to get more technical information, you can use special service codes. These commands are entered in the Phone app just like you would a regular number to call. After entering the last digit or symbol * or # the system will automatically redirect you to a hidden menu.
The most universal code for checking IMEI and model is *#06#. After entering it, a window with identification numbers will appear on the screen. Although this code does not always show the brand name in text, the first 8 digits of IMEI (TAC) can accurately determine the manufacturer in open databases.
For devices from Samsung the code often works #1234#, which displays the firmware version (PDA, CSC, MODEM) and device model. Smartphone owners Xiaomi can try the combination ##6484##* to enter the CIT engineering menu, where the exact model name is usually duplicated at the very top of the list.
What to do if the code does not work?
Not all codes work on all devices. Manufacturers often block access to engineering menus on global firmware versions or on devices purchased from official dealers in certain regions. If the combination does not give a result, simply remove the numbers and try the next method.
Checking through applications from Google Play
When built-in tools do not provide a complete picture or raise doubts about reliability, third-party utilities come to the rescue. In the store Google Play there are dozens of applications for hardware diagnostics that read information directly from kernel system files, bypassing the graphical shell.
One of the most popular and reliable tools is the application CPU-Z. Once installed and launched, it immediately displays tabs with detailed information. On the Device tab, you will see the Brand, Model, and Manufacturer fields. This data is almost impossible to falsify programmatically at the firmware level without deep flashing the device.
Another powerful tool is AIDA64. This application provides a comprehensive report of all the components of the smartphone. It will show not only the phone brand, but also the actual screen resolution, the number of processor cores and the type of camera sensor. This is especially useful for identifying counterfeits, where the stated characteristics are often overestimated.
- 📱 CPU-Z - a lightweight tool that shows basic information about the brand and hardware.
- 🔍 AIDA64 - a professional combine for detailed diagnostics of all subsystems.
- 🛠️ Device Info HW - a specialized application that often sees the camera and screen model even where others pass.
Third-party applications read data from system kernel files, so they are the most reliable way to find out the real characteristics, even if the settings menu has been modified.
Visual inspection of the case and battery
In the era of non-removable batteries, this method seems outdated, but it is still relevant for certain models and situations. Manufacturers are required to mark the device body in accordance with the legislation of most countries. These inscriptions may be small and located in non-obvious places.
Carefully inspect the back cover of the smartphone. Even if the brand logo has been erased, there is often small text with the serial number (S/N) and model. If the battery is removable, the information is guaranteed to be underneath it. To access, you need to turn off the device, remove the back cover and remove the battery.
The factory sticker under the battery usually contains a complete summary:
Model: XYZ-123
IMEI: 123456789012345
Made in China/Vietnam/India.
This data is “reinforced concrete” proof of the origin of the device, since the sticker is applied at the factory.
| Location of the marking | Type of information | Reliability |
|---|---|---|
| Menu “About phone” | Commercial name | Average (can be faked) |
| Sticker under battery | Serial number, Model | High |
| Packaging (box) | Full specification | High (if the box is original) |
| SIM card tray | Model (sometimes) | Low (rarely indicated) |
⚠️ Attention: Be extremely careful when removing the back cover. Do not use metal objects that could damage the contacts or puncture the battery. If the cover does not come off easily, do not use force - it may not be removable in your model.
Analysis of packaging and accompanying documents
If the smartphone was purchased new or you saved the original box, then this is the fastest source of information. Manufacturers apply a sticker with technical data to one of the edges of the packaging. This sticker usually contains barcodes, IMEI and the exact model name.
Compare the data on the box with what is displayed on the screen of the phone when it is turned on. A matching IMEI on the box, in the phone settings and (if possible) under the battery guarantees the authenticity of the device. A discrepancy in even one IMEI digit may indicate that the phone was refurbished or assembled from different parts.
Also check the warranty card or user manual. In modern conditions, instructions are often presented in electronic form, but a paper version is still found. On the first page or on the cover of the booklet, the series of devices for which it is intended is always indicated.
☑️ Authentication by box
Search by photo and appearance
If the phone does not work completely, the screen is broken or the device is locked, you can determine the model by external signs. The location of the cameras, the shape of the lens unit, the presence of a fingerprint scanner and connectors are all unique features of a particular model.
Take a high-quality photo of the front and back panels of the smartphone. Upload the image to the service Google Lens (Lens) or use image search in Yandex or Google Images. Artificial intelligence algorithms recognize visual patterns with high accuracy and provide a list of similar devices.
Pay attention to unique design elements. For example, a retractable camera is typical for some models of Xiaomi and OnePlus past years, and periscope zoom is often found in flagships Huawei and Samsung. Knowing these features, you can narrow your search to a specific year of manufacture and series.
⚠️ Attention: The interfaces and design of smartphones change every year. What was true for the 2020 model may be different for the 2026 version. Check the images you find with the official press renderings on the manufacturer’s website.
When searching by photo, try to remove covers and protective glass from the frame. They can distort the contours of the device and prevent recognition algorithms from accurately identifying the model.
Frequently asked questions (FAQ)
How to find the phone model if it does not turn on?
If the device does not show signs of life, the only way is a visual inspection of the case. Look for the engraving on the back cover or remove it (if the design allows) to find the sticker under the battery. Searching for a photograph of the appearance via Google Lens will also help.
Why is one name written in the settings, but another in the CPU-Z app?
This is a common sign of a fake. Fraudsters modify the system file build.propso that the name of the flagship is displayed in the settings menu (for example, Samsung S23 Ultra), but during deep diagnostics the app sees the real hardware of a budget Chinese smartphone.
Is it possible to find out the phone brand by IMEI without turning on the device?
Yes, IMEI is often laser engraved on the device body or on a sticker under the battery. Knowing these 15 digits, you can use online IMEI checking services that will tell you about the brand, model and release date of the device.
What is the technical model code and why do you need it?
The technical code (for example, SM-A515F) is the internal identifier of the manufacturer. It is needed for accurate selection of spare parts, since externally identical phones may have different motherboards or screens depending on the sales region.
Where can I find the serial number on Android?
The serial number (S/N) is usually duplicated in the menu Settings → About phone, on the factory sticker under the battery and on the original packaging devices. It is unique for each specific instance.
