The smartphone market is crowded with devices, and the Xiaomi Poco X3 NFC has become one of the most popular models, which inevitably led to the emergence of many fakes. Customers often face the dilemma of how not to become a victim of fraud and buy exactly the device for which the money is paid. On the surface, replicas can be almost indistinguishable from the original, but the internal stuffing and software give them away.
The process of verification of the gadget requires care and knowledge of several technical nuances, which we will discuss in detail in this material. the originality of the device guarantees not only the declared performance, but also the security of your personal data, as well as the ability to receive official updates. Ignoring checks can lead to the purchase of a brick with stripped functionality.
In this article, we'll take you through all the methods available, from visual inspection of the case to deep analysis of system files. You don't have to be an electronics expert, you just have to follow the step-by-step instructions. We'll look at how to use official Mi Verify services, analyze screen and camera parameters, and check the integrity of the factory firmware.
Visual inspection of the body and configuration
The first thing that starts is to look at the look of the device carefully, and the build quality of the original Poco X3 NFC is always high: the gaps between the screen and the frame are minimal, and the power and volume buttons are not backed up. There should be no glue or irregularities on the back, especially around the Poco logo.
Pay special attention to the screen. The original uses quality glass with an oleophobic coating that feels good to the touch and does not collect fingerprints as quickly as cheap counterparts. Color rendering and viewing angles of the IPS matrix are also important markers: in fakes, the picture often looks faded or has a noticeable yellowish hue.
⚠️ Note: If you see the “Mi” logo instead of “Poco” when you turn on your phone, or «MIUI for POCO», This may indicate a reflashing of the global version or the installation of custom software on the Chinese model, which requires additional verification.
The package can also tell you a lot. The original box is made of dense cardboard with clear printing. Inside you'll find a USB Type-C cable, a protective case and a scratcher, but the charger may not be included depending on the region of delivery. All documents must be printed on quality paper without typos.
- 📦 Check for a protective film on the screen with factory markings.
- 🔍 Check the connectors: in the original they are painted black and have no backlash.
- 🖨️ Logos on the back panel should be applied by laser engraving or high-quality embossing.
💡
Note the weight of the device: the original Poco X3 NFC weighs around 215 grams, whereas counterfeits are often lighter due to the use of cheap materials and a smaller battery.
Checking IMEI and serial numbers through official services
The most reliable way to verify authenticity is to verify the unique IDs of the device.Every Xiaomi smartphone has a unique one. IMEI (International Mobile Equipment Identity, and the serial number, and you can find this data on the box, under the tray. SIM-maps or system settings along the Settings path → The phone.
To check, go to the official Mi Verify website or use the Mi Community app. By entering the IMEI and serial number, the system will give information about the model, activation date and warranty status. If the site reports that the number is not found or the device is already activated long before you buy, this is an alarm signal.
You can also use it. USSD-commands to display information on the screen. dial *#06# in the Phone app to see IMEI. Compare these numbers to the ones on the box. In the original devices, all the numbers are the same, whereas in the replicas, there is often a mismatch between system data and stickers.
| Parameter | Original | Fake. |
|---|---|---|
| IMEI in the system | It matches the box. | Oftentimes not the same. |
| Serial number. | There's a Xiaomi website. | Not in the database. |
| Activation date | Coincides with the purchase | Past date indicated. |
| Status of guarantee | Active. | Gone or unknown |
Analysis of technical characteristics and productivity
Internal components are the hardest to fake. The Poco X3 NFC is based on the Snapdragon 732G processor, which ensures stable performance in heavy games and applications. Counterfeiting is often equipped with weak MediaTek chips that are only disguised as Qualcomm through software modifications.
For a detailed check, use specialized applications such as CPU-Z, AIDA64 or Device Info HW. They will show the real name of the processor, the number of cores, the frequency and type of RAM. If the application shows 8 cores, but the frequency is much lower than the declared, or the processor model is in doubt, you have a copy.
⚠️ Note: Software tests like AnTuTu can be modified into fake firmware to show falsely high results. Always double-check the data through several different utilities.
The amount of RAM and internal memory is another common subject of manipulation. Vendors can programmatically change the display volume, but when the memory is filled, the device will start to emit errors. Record the amount of free memory, install a large file or application, and check whether the declared space has disappeared.
- 🚀 The original Snapdragon 732G dialing in AnTuTu v9 about 330,000 to 350,000 points.
- 💾 The actual memory is always slightly less than claimed due to system files, but not many times.
- 🌡️ When loaded, the original warms moderately, fakes can overheat instantly.
How to change the amount of memory?
Checking the display, camera and sensors
The Poco X3 NFC screen has a refresh rate of 120 Hz and a resolution of 2400×1080 pixels. The screen settings menu (Settings → Screen → Update Frequency) should have an option to switch between 60 Hz, 90 Hz and 120 Hz. In counterfeits, this feature is often absent or only works in words, remaining at 60 Hz.
The camera is one of the most complex modules for high-quality cloning. Sony's IMX682 64MP core module takes detailed images even in good light. Replicas have cheap sensors at 2-8 MP, interpolated software to 64 MP. The photo quality will be low, with noise and blur, and zooming will turn the picture into mush.
Make sure you check all the sensors. Hold your phone to your ear when you call, the screen should go out (approximation sensor). Turn the device, the picture should rotate (accelerometer). In the original, all the sensors work instantly and accurately, while in copies they may be late or not working at all.
☑️ Multi-touch and screen check
It’s also worth checking out the stereo speakers, as the Poco X3 NFC is equipped with a full stereo system.The sound must be loud, clean and come from both the bottom and top speakers (which are often combined with a spoken one).
Software and firmware diagnostics
The official shell of MIUI (or HyperOS) has its own unique features that are difficult to fully copy. The interface should be smooth, without jerks and sudden drops of applications. Fakes often contain Chinese characters on the menu, missing translations or Google system applications that do not work.
Check for GetApps store and Mi Credit service, which are pre-installed on the originals. Also important is the ability to upgrade the system over the air (OTA). Go to Settings → About Phone → MIUI version and click three dots in the corner, selecting Update Options. If the phone says that there are no updates, although for your version they are already out, this is a reason to be alert.
Data security is critical: Fake firmware often contains hidden backdoors and malware that steals passwords and bank details. Original devices undergo rigorous Google Play Protect security checks and have a certified level of protection.
⚠️ Note: If when you try to unlock the bootloader (Bootloader) of the Mi Unlock Tool utility gives an error or the device is not detected, perhaps this is not the original device or the firmware is modified unprofessionally.
💡
The inability to update via OTA or persistent errors when loading pages in the browser (even with the Internet) is a sure sign of the “curve” of global firmware on a Chinese device.
Engineering menus and hidden tests
Xiaomi smartphones have a hidden CIT (Customer Information Test) engineering menu designed for factory diagnostics. To get there, dial the combination ##6484## or ##64663##. Here you can test each component of the device individually: vibrator motor, GPS, sensors, microphones and network.
Go through all the menu items. If a test doesn't run, or if it gives you an error or a Fail result, it indicates a problem with the hardware or an emulation of it, for example, a GPS test should show coordinates, and a network test should show the signal level and type of connection.
Commands for rapid diagnosis:
#6484## - The basic engineering menu (CIT)
*#06# - IMEI check
#4636## - Phone information and usage statisticsThe engineering menu also shows the actual model of the device in the line "Model." For the Poco X3 NFC, the model should be designated M2006J10CG (Global) or M2006J10CT (Taiwan/India). If you see other codes, such as those specific to the Redmi budget models or unknown designations, it's a fake.
- 📡 Wi-Fi test should show the ability to scan networks.
- 🔋 Battery test will show real capacity and wear status.
- 🎤 Checking microphones (main and secondary) is mandatory for calls.
