How to Find out Xiaomi’s Screen Model: The Complete Guide

Modern smartphones Xiaomi, Redmi and POCO are equipped with advanced AMOLED and IPS matrixes, which are produced by different suppliers, such as Samsung, LG or BOE. Often there is a situation when you need to accurately identify the display installed in the device, for example, to replace broken glass or buy a compatible touchscreen. Just look in the settings “About phone” is not enough, since it indicates only the general name of the model of the device, and not a specific component.

Owners of gadgets are faced with the fact that visually identical screens can have different plumes and plume locations, making them incompatible with each other. Model identification is a critical step before any repair or deep software setup. In this article, we will examine all available methods, from engineering codes to the use of specialized software.

Understanding which component is installed in your device will help avoid errors when ordering parts. We will look at both software and hardware ways to get this information so you can be sure of the result.

Use of engineering menus and secret codes

The fastest way to access hidden information about the components of a device is to use an engineering menu. MIUI (And the new version of HyperOS, which is now available, has special codes that allow you to access diagnostic tests, and you have to open the standard Phone app to run the menu and type the combination ##6484##. CIT (Customer Interface Test).

In the test list that opens, you need to find a item associated with the display, usually called Display, Color or Screen. When you click on it, you run a color and brightness test. However, to see technical information, you often need to click on a specific area of the screen or select a specific menu subitem if it is available in your firmware version. In some cases, the matrix model can be displayed in logs or when you click on the kernel version.

⚠️ Warning: Do not change the settings in the engineering menu unless you are sure of their purpose.Resetting the color calibration or touch screen without professional equipment can lead to incorrect operation of the touch layer.

Alternative code for some versions of MIUI is ##4636##. It opens the test menu where you can find information about battery and usage, but display data is less common there. If standard codes don't work, it's possible that your operator or firmware is blocking access to these features. In this case, you should try entering code ##3646633##, which is universal for MediaTek, but can work on some Snapdragon Xiaomi devices.

Using diagnostic codes is a safe method that doesn't require third-party software installation, and it works even on locked devices if the display and touchscreen are functioning, but the information here can be presented in a coded form that only service engineers can understand.

Applications for defining Android characteristics

If the engineering menu doesn't work, the Google Play Store will provide you with specialized apps that read information from Android system files and provide it in a user-friendly way. One of the most popular and informative apps is Device Info HW. Once installed and launched, you need to go to the Screen tab.

In this section, the app will show not only the resolution and density of the pixels, but also the name of the display driver. Often the "Driver" or "Panel" line indicates the matrix manufacturer's code, for example, the matrix manufacturer's code, mdss_dsi_s6e3fa3_ams450ef01_dsi_v01. Analyzing this line allows us to understand who made the screen, such as codes that start with the screen. s6e, They often point to Samsung and ili to Samsung. ILI Technology.

💡

Pay attention to the resolution in the application: if the specified 1080x2340, and the specifications are stated 1080x2400, it may be a non-original copy of the screen or the driver is configured incorrectly.

Another powerful tool is the AIDA64 app, which provides comprehensive information about all components of a smartphone. After you launch, go to Display, where you will find data on current resolution, aspect ratio, and, importantly, supported modes. While AIDA64 does not always spell the model name in letters, it shows the technical parameters by which you can identify the component.

• 📱 Device Info HW — Best App for Viewing Drivers and Specific Panel Model.
• 📊 AIDA64 — Detailed technical specifications and supported modes.
• 🔍 CPU-Z — displays the basic resolution and pixel density (DPI).
• 🛠 Touch Screen Test – helps to check the performance of the sensor, but does not show the model.

Using third-party software requires a working operating system, and if the screen is so broken that the image is not readable, this method is not suitable, but for software testing before buying parts, this is the most accurate way.

Visual inspection and marking on the plume

When software methods are unavailable or the screen is not working at all, the only sure way is to physically inspect the phone, which requires gently opening the smartphone case and disconnecting the display plume from the motherboard, and on the back of the matrix, on the flexible plume, there is always factory marking.

Labeling usually looks like a set of numbers and letters printed in white or black. For example, the code may look like FPC-FFC013501-01-E or contain a manufacturer name such as Huaxing, Tianma or Visionox. This is the code you need to look for when ordering a spare part. Visual comparison of the plume of the old and new screen is a must.

⚠️ Warning: Display plumes are extremely fragile. Any attempt to straighten the crease or excessive tension will lead to a break in the tracks and complete inoperability1 of the screen.

Notice the number of contacts in the connector and its location (left, right, or center). Even if the screen model is the same name, the physical geometry of the plume may differ in different revisions of the same phone model.

Analysis of system logs through ADB

For advanced users who have access to debugging USB, The perfect tool is Android Debug Bridge (ADB). This method allows you to pull raw data out of the system that is not displayed in the normal interface, USB-cable and on-line debugging USB menu "For developers».

When you connect your smartphone to your PC, open the command line and type a command to output display information. Most often, the panel data is contained in the kernel logs or system properties. Use the command:

adb shell dumpsys SurfaceFlinger | grep -i"panel\|display\|model"

You can also try asking for properties directly through getprop. Enter the command adb shell getprop | grep -i display or adb shell getprop | grep -i panel. In the output, you can see lines containing the manufacturer's name or driver model, which is especially useful if the touchscreen is not working well and you can't fully use the interface.

If standard queries fail, you can try to count the bootloader or kernel log immediately after you turn on, but this requires a deeper knowledge of Linux. For most cases, it is enough to check properties through getprop. This is a professional approach used by service center engineers.

Search by Part Number and Catalogues

If there's code on the plume, but it doesn't say anything, use search engines. Type the code into Google or specialty parts stores (AliExpress, eBay, local suppliers). Often the same screen is used in multiple phone models. For example, a matrix from the Redmi Note 9 Pro can fit into the Redmi Note 9S.

When searching, look at the plume photos. The location of the plume relative to the matrix itself (bottom, side) is a critical parameter. Also important is the width of the plume and the number of contacts. The tables below show examples of popular matrix codes for Xiaomi devices:

Using part directories allows you to double-check the data. If you find a screen with code that's listed behind another model, but it's physically identical to yours, it's probably a compatible counterpart.

Frequent problems and compatibility of displays

Xiaomi owners often face a situation where the phone stops seeing brightness or only 50% of the touchscreen is working after changing the screen, because the same phone model could have screens from different vendors at different release periods, for example, in the Redmi Note 8 Pro, there were matrixes from Samsung and Tianma that are not compatible with each other.

The compatibility problem is solved only by precise matching. If you bought a screen that does not fit, software "flash" it for another type of matrix is impossible, because the power controllers and drivers are different physically. At best, autobrightness will not work, at worst, the phone will go into a bootloom.

• 🔌 Connector: Make sure the number of pins matches (for example, 30 pin vs. 34 pin).
• 💡 Backlighting: Different types of backlights require different controllers.
• 🖐 Touchscreen: Often sold with a matrix, but may be separately.

💡

Never rely on the name of the phone model when ordering a screen. Always open the device and check the code on the plume with the part code.

Also worth mentioning is the “True Tone” problem, which may be a problem for some Xiaomi models, which may be due to the loss of automatic color temperature adjustment, requiring re-solding of the memory chip from the home screen to a new one, or using a programmer, which is a complicated procedure.
