How to Check the Originality of Xiaomi Redmi 9: The Complete Guide

Buying a budget smartphone in a crowded electronics market always comes with the risk of encountering unscrupulous sellers. Xiaomi Redmi 9 has become one of the most popular in its segment due to its excellent price-performance ratio, which unfortunately attracted the attention of counterfeit manufacturers.

In this article, we will take a look at all the ways you can verify your device, from visual inspection to deep log analysis. You don't have to be an expert in the mobile world to detect counterfeits if you know what details to look for. Careful inspection before you buy or immediately after you receive the product will save you nerves and money.

There are many nuances that distinguish the original gadget from the copy, and we'll look at them in order of increasing complexity. Start with simple visual features and end with technical methods of checking through special services. The only way to get a 100% guarantee is to buy from official partners, but even when ordering from marketplaces you can protect yourself.

Visual inspection of the shell and packaging

The first thing that customers face is the exterior of the device and the box. Xiaomi's original products are famous for their attention to detail, while fakes often give off careless assembly. Pay attention to the quality of plastic or glass: the original should not have gaps between the case and the screen, and also backlashes of buttons.

Packaging is also an important indicator: the box should be printed on dense cardboard with clear, bright colors and the right typography. Fakes often have blurred logos, brand spelling errors or mismatches. Check if the protective film is on the screen - the original is perfectly flat, without bubbles or dust underneath.

Look at the jacks and the speaker holes. In the original Redmi 9, all the holes are lasers with the same pitch and diameter. If you see the rough edges, the residue of glue around the tray. SIM-A card or a poorly fitted charging connector is a wake-up call. The build quality is the first thing that catches the eye of an experienced user.

⚠️ Note: If the box or device itself has performance stickers glued over others or has autopsy marks, this may indicate an attempt to hide the actual configuration or delivery region.

IMEI and serial number verification

Every legitimate smartphone is assigned a unique IMEI (International Mobile Equipment Identity) ID, a kind of device passport that cannot be changed at the software level without violating the laws of chip physics. On the original Xiaomi Redmi 9, this number must match in three places: on the box, on the system menu and on the engineering menu.

To quickly check, type *#06# on your phone keyboard. The screen will display IMEI data. Compare it to the number printed on the sticker at the back of the box. If the numbers are different or you see dashboards instead of numbers, you clearly don't have the original in front of you. You can also find IMEI in the Settings menu → Phone → General Information.

The resulting code must be entered on the official Xiaomi website or through specialized verification services. Enter the number in the warranty check box on the manufacturer's website. The system must show the exact model of the device, the date of activation and the remainder of the warranty period. If the service writes "Not found" or shows a model of another phone, it is a fake.

Analysis of the MIUI operating system

The software shell is another critical test point: the original Xiaomi Redmi 9 runs on Android with a MIUI shell (or its modern version of HyperOS), which has a specific interface and functionality. Counterfeiting often runs on stripped-down, older versions of Android that only visualize the design of MIUI.

Look at the fonts, transition animations, and the presence of standard Xiaomi apps like Security, Mi Credits, Mi Videos. These apps are either missing in fakes or are simple shortcuts leading to web pages. The original system runs smoothly, while clones often slow down even in simple menus because of a weak processor.

Try going to the update menu. The original device will be able to check for updates and, if any, suggest installation. In fakes, the update button either doesn't work or gives a connection error. Also check for the Google Play Store - in Chinese versions it is not out of the box, but it can be installed, while in fakes it is often already built in, but it does not work properly.

Performance and performance testing

Often sellers of counterfeits indicate in the characteristics of overestimated parameters, for example, 128 GB of memory instead of real 16 GB or 8 GB of RAM instead of 2 GB. To check the real state of affairs will help specialized applications. Download from the Play Store utility CPU-Z or AIDA64.

These programs will show the exact model of the processor, the number of cores, the actual screen resolution and memory capacity. The processor in the original Redmi 9 is the MediaTek Helio G80. If the program shows the MediaTek MT6580 or any other chip, it's 100% fake. Also note the screen resolution: the original has 1080 x 2340 pixels, and copies often have matrixes with a resolution of 720 x 1560 or lower.

Do a memory test. Cheap copies often reflash the memory controller to show the full volume, but when you write data beyond the real limit, the phone will freeze or data will be lost. Apps like Fake Device Test can detect such fraud by writing test files to the disk.

Camera and multimedia check

The camera is one of the most expensive components of a smartphone, so it is saved first. The original Redmi 9 features a 13 MP main module that takes detailed pictures in good light. Counterfeit lens often have only one working lens, and the other three serve only as scenery.

Take some photos and look at them in full size. If you see "porridge" instead of details, lack of focus or compression artifacts, this is a sign of a cheap matrix. Also check the zoom: in the original digital zoom works software, and in fakes, switching between cameras can simply change the software filter.

Notice the quality of the video and the sound. The original device writes sound in good quality, and the video is stabilized software. In copies, the sound can be deaf, and the video can twitch. Check also the flash — it should be bright and white, not dull and yellow.

💡

Take a test photo of the text at a distance of 15 cm The original macro camera (if supported by software) or the main module will give readable text, and a fake will turn it into a blurred spot.

Use of service codes and engineering menu

For deep diagnostics, you can use hidden Android menus. Enter ##6484## (or #4636##) in the Phone app. This code opens the CIT (Customer Information Test) engineering menu, where you can check the operation of all modules: vibrator, screen, sensor, speakers and cameras.

Go through all the test items. In the original device, all the tests must be run and run correctly. In fakes, many items can be non-working, give out errors or just return you to the main menu. Especially the sensor test is indicative: swipe your finger across the screen, and all the dots should be colored.

You can also see the exact information about the MIUI version and build date on the engineering menu, check this with the information on the official website, and if the build date is a few years after the model is released, or retroactively, this is a reason to doubt the authenticity of the firmware.

⚠️ Warning: Do not change the settings in the engineering menu unless you are sure of their meaning. Resetting the screen or radio module calibration can lead to malfunctioning of the device, which is difficult to fix without flashing.

Comparison of equipment and accessories

In the box with the original smartphone always lies a full set of documents: warranty card, instructions in several languages, a paper clip for SIM extraction and a protective case (in some regions), the quality of printing instructions should be high, the text is clear, without spelling errors.

The charger and cable also have differences: the original power supply has clear labeling, smooth plastic seams and appropriate safety certificates. The USB cable must be tight, with the Xiaomi logo (the small letter "mi" on the plug). In fakes, the cable is often thin, flexible as noodles and has no logo.

The screen protector often has a "mi" logo or removal instructions. It can be a transparent silicone bumper that fits the body perfectly. If the case is crooked, smells of rubber or covers the microphones, it's a sign of a poor-quality copy.

💡

The package may vary depending on the region of sales (Global, China, Europe), so the absence of items (for example, charging in European versions) does not always indicate a fake.
