How to check the phone for the originality of Xiaomi Redmi 9

Buying a budget smartphone like the Xiaomi Redmi 9 often comes with the risk of a poor-quality replica, as it is popular models that are most often copied by unscrupulous manufacturers. The market is saturated with devices that are almost indistinguishable from the original, but inside have outdated hardware, poor cameras and software devoid of key security features. Verification of the gadget becomes a critical task immediately after unpacking to avoid financial losses and frustration from the slow operation of the device.

There are many ways to determine with high accuracy whether you are holding a real original smartphone or a cheap fake. We will look at both software methods for analyzing the system through the settings menu and special codes, and a physical examination of the case, display and components. A careful study of each item of the instruction will help you confidently verify the quality of the device you purchased.

Ignoring the initial diagnosis can lead to a device with a fake battery that is dangerous to health, or a screen that does not transmit real colors. A key marker of counterfeiting is often the inability to log into an official Mi Account or the lack of Google Play Protect certificates. Let's take a detailed look at all the stages of verification, from the appearance to the in-depth analysis of the system.

Visual inspection of the body and configuration

The first thing that catches your eye when you look at the device is the build quality and materials. The original Redmi 9 is made of high-quality plastic with a texture that mimics glass, and has smooth, bulging edges. Carefully examine the joints between the back cover and the frame: the gaps should be minimal and uniform throughout the perimeter, and when pressed, the body should not creak or bend.

Pay special attention to logos and inscriptions. On the back of the original, the MI logo is clearly marked, without lubricated edges and easily erasable spray. On the lower face of the device, there must also be markings, including model, country of manufacture and certification marks (CE, FCC), which on copies often look pale or contain grammatical errors in the English text.

⚠️ WARNING: If the Xiaomi logo peels off on the back of your smartphone with light nails or has a glossy shine instead of a matte, this is a sure sign of a low-quality replica.

The kit also tells us a lot about the origin of the device. USB Type-C, paper clip for extraction SIM-maps, protective cover and documentation in multiple languages. The cable should be tight, with clearly cast connectors and logo MI, whereas in copies the wires are often thin, light and without any markings.

Analysis of display and matrix

The screen is one of the most expensive components of the smartphone, and that is where counterfeit manufacturers save the most.The original Redmi 9 features an IPS LCD matrix with a resolution of 1080 x 2340 pixels and a pixel density of about 395 ppi. The picture should be clear, with excellent viewing angles, and black on a white background should not give a blue or gray hue, which is typical for cheap TN-matrixes.

You can check the screen quality by turning on the white image at maximum brightness. The uniformity of the backlight is an important indicator: the original should not have noticeable yellow spots or dimming at the edges (the “clouding” effect). It is also worth checking the sensor’s performance: the multi-touch in the original device supports up to 10 simultaneous touches, whereas copies often react only to 2-3 points or have “dead zones” at the edges.

💡

To check the multi-touch, open any graphics editor or special game and try to touch the screen with all your fingers at the same time – the original will draw all the dots without delay.

Brightness and automatic adjustment are another test. In the Settings menu → Screen, try changing the brightness level: the slider should move smoothly, without jerking. The light sensor in the original works correctly, darkening the screen when you bring the phone to your face during a conversation, which is often implemented incorrectly or not at all in copies.

IMEI and serial number verification

The most reliable way to digitally identify a device is to reconcile IMEI-Every legal smartphone has a unique identifier that you can find by typing the universal code *#06# in the Phone app. SIM-map IMEI, which must match the information pasted on the box and (if the battery is removable) under the back cover.

The resulting code must be checked on the manufacturer's official website. Go to the Xiaomi authentication portal and enter your IMEI in the appropriate field. The system will tell you whether such a device exists in the database and whether its model corresponds to the stated one. If the site writes "Invalid IMEI" or shows a model of another phone (for example, Redmi 8 instead of the 9th), you are a fake.

• 📱 Type *#06# in the Call App to get the code.
• 🌐 Go to the official verification site MI Verify.
• ✅ Compare the data on the screen, box and in the site database.
• ⚠️ Pay attention to the amount IMEI: There should be two of them, as Redmi 9 is two-sim.

It is important to remember that fraudsters have learned to steal. IMEI-codes, so the matching of the number on the site does not give 100% The guarantee, but the mismatch is a guaranteed sign of a problem (S/N), This is also shown in the system information and on the packaging, and in the original devices, this data is strictly unique and does not repeat itself.

Diagnostics through engineering menu and codes

The MIUI operating system installed on the original devices contains a hidden engineering menu for testing hardware components. To get there, use the code ##64663## (or #4636## for basic information). If nothing happens after you enter the code or the standard Android menu opens, this is a clear sign of modified or stripped-down firmware on the copy.

The CIT menu provides a complete list of all the phone modules, from the accelerometer and gyroscope to the cameras and speakers. Once you pass the tests, you can verify the performance of each element. For example, the Touchpanel test will draw lines throughout the screen and make sure that the sensor responds at every point, and the Receiver test will check the audio speaker.

Pay particular attention to the Version Information section. This shows the exact processor model, the amount of RAM and internal memory. Often copies of software "paint" high performance (for example, 64 GB of memory instead of the real 8 GB), but in the engineering menu or when you try to write a large file can open a real, much smaller volume.

Analysis of the MIUI operating system

The interface and functionality of the MIUI shell is the “soul” of the Xiaomi smartphone, which is extremely difficult to copy. The original system is characterized by smooth animations, the presence of all standard applications (Mi Browser, Mi Video, Mi Music) and the ability to update “over the air” (OTA). In the Settings → About the phone should be able to click on the version of MIUI and check for updates.

The original Redmi 9 comes with a pre-installed Google Play Store and all the necessary security certificates. Try logging in to your Google account: if the system issues a connection error or writes that the device is not certified, it is an alarm. Also in the original Google Pay feature (or its analogues), which on modified copies is often blocked.

⚠️ If the phone settings indicate a version of Android newer than officially released for this model at the time of its release, or vice versa – too old for the current year, this is a sign of firmware reflashing.

Testing of cameras and multimedia

Cameras in budget smartphones are often manipulated: instead of the four modules on the back, only one can actually work, and the rest are just scenery. Open the camera app and try to switch between Shireek, Macro and Portrait modes. If the image does not change when you switch, a black screen or an error message appears, then the additional cameras are fake.

The quality of the shooting also speaks volumes about the origin of the device: the original Redmi 9 camera (the main module 13 MP) takes detailed pictures in good light, while copies often sin digital noise, blurry detail and unnatural color reproduction even during the day. The video in the original is written with normal bitrate, while on fakes it can twitch or have a desynchronization of sound.

Remember to check the main speaker and microphone. Write down a dictaphone note and play it back: the sound must be clean, without wheezing or prying. When talking, the person must hear you clearly. Cheap copies often have low-quality microphones that transmit voice as "from the barrel" or with strong echoes.

Performance and battery check

The MediaTek Helio G80 processor installed in Redmi 9 provides a confident performance in everyday tasks. Run a heavy application or game: the interface should not frieze, and applications should fly out. For objective evaluation, use benchmarks such as AnTuTu or Geekbench. The original device will score about 200,000 points in AnTuTu (version 8/9), while a copy with a processor level Helio A22 will show the result 3-4 times less.

Battery capacity in the original is 5020 mAh. Real life should correspond to the stated: when used actively, the smartphone holds a charge of 1.5-2 days. Copies are often equipped with batteries with a capacity of 2000-3000 mAh, which can discharge in half a day, despite the system readings of 100%. Also pay attention to the charging speed: support for 18 W in the original provides a full charge in about 2.5-3 hours.

• 🚀 Install AnTuTu Benchmark to check the hardware".
• 🔋 Set charging time from 0 to 100%.
• 📉 Watch for heating: the original warms moderately, the copy may hot.
• 📲 Check the work. GPS map-walking.

⚠️ Note: If the smartphone is charged before 100% post 30-40 minutes, but sits down for 2-3 an hour of operation, this is a sign of a cheap battery with a controller that incorrectly displays the level of charge.
