How to find out the full information about Xiaomi phone

Owners of Xiaomi, Redmi and Poco smartphones often face the need to obtain comprehensive data about their device, which may be necessary to verify the authenticity of the gadget before buying, clarify the exact version of the firmware for installing patches or simply to fill out a warranty card.

Android, in conjunction with the MIUI or HyperOS shell, provides a host of hidden tools and codes that allow you to look deeper than conventional applications. In this article, we will explore all the available methods, from simple menu paths to the use of engineering codes and third-party software, you will learn to find hidden parameters that are usually not available to the average user.

Proper identification of the model and components is critical when searching for drivers or parts. An error in determining the motherboard version can lead to the purchase of an incompatible battery or display. It is therefore important to be able to read accurate data directly from the system, avoiding possible marking errors on the box.

Standard settings and menu "About the phone"

The most obvious, but not always informative, way is to use the basic settings menu, and that's where you start to get to know the device, but what many users don't realize is that the sections hidden behind the icons have a lot more data if you know where to click. First, go to Settings and select About.

This shows the device model, the Android version and the MIUI build number. But the real magic starts when you interact with this screen. If you quickly click 7-10 times on the logo of the version of the system (for example, MIUI 14 or HyperOS), you turn on a hidden menu of advanced data, which will show parameters such as the kernel version, the base version of the modem and the exact firmware compilation date.

⚠️ Warning: Do not try to change the values in the engineering menu unless you know exactly what each parameter is responsible for.

The extended menu also often has Android ID and OAID, which is used by ad networks instead of Google Advertising ID. This data is useful for debugging apps or completely clearing the digital footprint. Remember that the standard menu won't show you real-time battery status or CPU temperature under load.

Use of the engineering menu and USSD-code

To get more technical information, including data about the radio module and sensors, special character combinations are used. In the Xiaomi phone, the main tool is the engineering menu, which is accessed through a standard “bell ringer.” Enter the code # #64663## to start testing equipment.

This is a factory diagnostics mode, but it's also very useful for users, so you can test each sensor separately, like the accelerometer, the gyroscope, the proximity sensor, and the microphones, and if your phone is acting strangely in games or when you're talking, that's where you can tell if the hardware is to blame or if the software is shattered.

• 📱 Version Information – shows detailed information about the radio module version and base station.
• 📶 Phone Information – here you can see the signal level in dBm, the type of network (LTE/5G) and cell IDs (CID, LAC).
• 🔋 Battery Info – displays the real capacity, voltage and temperature of the battery, bypassing system limitations.
• 📡 WiFi Test – allows you to check the work of Wi-Fi antennas and see MAC-interface addresses.

Another useful code for collecting information — *#06#. It instantly displays all device identifiers on the screen: IMEI each SIM-map, MEID and serial number S/N. This data is critical when blocking a lost phone through an operator or when checking a device based on stolen gadgets.

IMEI verification and device authentication

The question of device authenticity is especially acute when buying a smartphone from hand or in unverified stores. IMEI (International Mobile Equipment Identity) is a unique 15-digit number that is assigned to each mobile device.

To verify the authenticity, Xiaomi offers an official service. You will need a serial number (S/N) or IMEI. Enter this data on the official verification website. The system will not only report the existence of the device in the database, but also the date of first activation, as well as the status of warranty service.

⚠️ Note: If the site shows that the device was activated long before your purchase, this may indicate a refurbished device or a used phone being issued as a new one.

Global versions of Redmi and Xiaomi have an Android logo when booting, while Chinese versions (CN) often lack it or have specific labels.Reflashing the Chinese version to the global version requires unlocking the bootloader, which is a complicated procedure in its own right.

Specialized applications for diagnostics

When built-in tools are scarce, third-party apps from Google Play come to the rescue, reading data directly from sensors and system files, providing information in a graphical way. One of the most popular and reliable tools is CPU-Z or AIDA64.

These snails show not just the model of the processor, but the actual state of the processor: the current core frequency, temperature, voltage and load. You can see which SoC (System on Chip) core is working at the moment and how efficiently the cooling system is coping with heating, and this is especially true for gamers.

Another useful software is Device Info HW. This app specializes in camera and display details. It can tell you which manufacturer (Samsung, Sony, Omnivision) is using your phone, as Xiaomi often changes component suppliers within the same model.

• 📊 Data Accuracy – Applications read information directly from the system kernel, eliminating software distortions.
• 📈 Real-time monitoring – the ability to see changes in parameters (e.g. battery wear) in dynamics.
• 💾 Report export – many programs allow you to save a report in a text file or send it by email.

💡

Third-party apps are the best way to know the exact model of the screen matrix and the camera sensor, as the manufacturer often doesn’t specify these details in the specs.

Obtaining data via computer (ADB and Fastboot)

For advanced users with access to a PC, the most powerful tool is ADB (Android Debug Bridge) debugging, which allows you to pull out of your phone absolutely any information available to the system, including hidden logs and configuration files.

To start, you need to turn on the developer mode. Go to Settings → About Phone and 7 times click on the version of MIUI. Then in the menu "Advanced settings" activate the item "Debug on USB." Connect the phone to the computer with a cable.

Using the command line on a PC, you can request a list of all connected devices and their serial numbers. the adb devices command will show the base status, and you can use the command to get details about the build:

adb shell getprop ro.build.fingerprint

This command will return a string containing the brand, model, Android version, build number and device type, and through ADB you can find out the exact screen resolution, pixel density (DPI) and the list of installed packages, an indispensable tool for those who are engaged in system modification.

⚠️ Warning: When connecting your phone to your computer in debugging mode, always check the debugging permission request on your smartphone screen. ADB may be unsafe.

Table of main characteristics and their importance

To structure your knowledge, consider the main parameters you can find and what they are responsible for. Understanding these terms will help you better navigate the technical specifications of your Xiaomi.

Knowing the exact model (e.g., the difference between Global Version and China Version) is critical when searching for firmware. Incorrect firmware can lead to a device “bricking” or inoperability of the NFC module and 4G/5G frequencies.
