How to know exactly the display model on the Xiaomi smartphone: from settings to disassembly

Are you trying to replace a broken screen on Xiaomi, but you don't know which panel to order? Or do you want to check the originality of the display after repair? Determining the exact matrix model is a critical step, on which compatibility, image quality and even sensor performance depend. In this article, we'll go through all the working methods, from hidden menus and engineering codes to physical disassembly of the device.

The problem is that Xiaomi (like most manufacturers) doesn’t put display information in the public settings, and even the documents on the device often only specify the type of matrix (AMOLED, IPS LCD), But it's not a specific model. And yet, for example, for the Redmi Note 10 Pro, there are at least 3 different screens from different vendors -- all of which are identical in appearance -- and a mistake in choosing will lead to color reproduction problems, autobrightness, or even a complete failure of the touchscreen.

We tested each method on devices of different lines - from budget POCO M3 The article is only up-to-date data for 2026, taking into account the latest updates. MIUI 15 and changes to service menus. If you need to get started, start with a list of engineering codes, if you're ready for a detailed review, read consistently.

Why it is so important to know the exact display model

At first glance, all screens for the same Xiaomi model are the same, but in practice even minor differences in markings (for example, in the same model, TDDI HLT vs. TDDI TCL) It leads to serious problems:

• 🔧 Firmware incompatibility: Unoriginal or mismatched displays may not support features like Always-On Display or 120Hz.
• 🎨 Distorted Color Rendering: Matrixes from Different Suppliers (Samsung, BOE, Tianma) have different color profiles. Without calibration, the colors will be "soapy" or oversaturated.
• 💸 Overpaying for unnecessary features: For example, a Dolby Vision-enabled screen for a model that doesn’t use it.
• ⚡ Problems with energy consumption: unoriginal AMOLED-panels can drain the battery faster due to unoptimized driver.

Most Xiaomi service centers keep silent about differences in displays, offering "universal" solutions, in fact, this often leads to the fact that after replacing the screen begins to flicker at low brightness or incorrectly display gradients, we collected data on the most common problems in the table below:

Critical: on AliExpress and other platforms, vendors often say “suitable for Xiaomi Redmi Note 10 Pro” but don’t specify the matrix model, which leads to the purchase of an incompatible panel in 80% of cases, and then we will show you how to avoid this error.

Method 1: Engineering codes – quick access to display data

The simplest method that works on 90% of Xiaomi devices without root rights.Using hidden service menus available through the set USSD-Important: Some codes may not work on custom firmware or devices with a locked bootloader.

Instructions:

1. Open the Phone app.
2. Enter one of the codes below (as a normal phone number).
3. If the code works, you will see a menu with technical information.

List of working codes for Xiaomi (2026):

• 📱 ##284## - Sensor test (shows a touchscreen model, but not always a matrix).
• 🖥️ ##36446337## - menu MIUI Display Test (on some models displays the display manufacturer).
• 🔍 ##4636## → Hardware info → Display (Works on Android 10)+).
• 🛠️ ##225## - Calibration of the display (can show the model in the header).
• 📊 ##6484## - Test MTK Engineer Mode (for devices on MediaTek).

If the code didn't work, try adding at the end (e.g. #36446337##**).Some firmware requires input via the Symbols app (instead of the standard number).

Try another code from the list|Reboot the phone|Check if the code is blocking antivirus/firewall|Use a third-party application (see Method 3)|Try to enter the code through the application "Symbols"-->

Example of result: POCO F3): When you type #36446337##, a line like Display appears at the top of the screen: SDC AMOLED FHD+, where SDC — This is Samsung Display.

⚠️ Note: Do not enter codes found on questionable forums - some of them (e.g. ##7780##) can reset your phone. MIUI 12–15.

Method 2: Hidden menu MIUI — codeless

If the engineering codes didn’t work, try to get information through hidden settings. MIUI. This method works on most devices, including Redmi, POCO Mi series.

Step-by-step:

1. Go to Settings. → The phone.
2. Find the MIUI version and tap it 7 times in a row (you should see the message "You became a developer").
3. Return to the main settings menu and open Additional → for developers.
4. Activate the Debugging option USB (Not necessarily, but it may help).
5. Now go to Settings. → System system → Advanced settings → Full specification.
6. Scroll down to the Screen block – the matrix model or manufacturer may be listed here.

On some devices (for example, Redmi Note 12 Pro)+) wayward:

Settings → About the phone → All the characteristics → Screen

If the specs don’t have any display data, try an alternative path:

Settings → Screen → Additional → Colors and contrast

At the top of this menu, the matrix manufacturer is sometimes displayed (e.g. Samsung). AMOLED or BOE LCD).

💡

If the settings don’t include display information, try changing the region of the phone to India or China – some firmware for these regions displays advanced data.

Nana POCO X3 Pro and other devices with Qualcomm Snapdragon can use another trick:

1. Install the app QDCM FF (qualcomm).
2. Launch it and go to Display. → Panel Info.
3. The display chip model will be indicated here (for example, NT36672C For the Redmi Note 9 Pro).

Method 3: Third-party applications – maximum detail

If standard methods fail, specialized utilities will come to the rescue, reading data directly from the display controller and often showing even the serial number of the matrix.

Top.-3 tested applications (2026 year):

• 📲 DevCheck (Google Play) – shows the display model in the Hardware section → Screen. It works without root.
• 🔍 AIDA64 (Google Play – Search for information in Display → Panel. Some devices require root for full data.
• 🛠️ CPU-Z (Google Play – Device section → Screen. less detailed but often shows manufacturer.

Example of data from DevCheck on Xiaomi 12T Pro:

Screen:




Resolution: 2712 × 1220 (120 Hz)




Density: 446 PPI


  Panel: Samsung AMOLED (SDC, E4)


Touch: Goodix GT9986

If the application only shows general information (for example, if the application shows general information, AMOLED FHD+), But not a model, try it:

1. Install root access (at your own risk!).
2. Use the application MTK Engineering Mode (for MediaTek) or Qualcomm Panel ID Reader (for Snapdragon).
3. Connect your phone to your PC and use ADB (instructions below).

⚠️ Attention: On devices with MIUI 14+ certain applications (e.g, AIDA64) They may show incorrect information about the display due to security restrictions. ADB squash.

Method 4: ADB-Teams – for advanced users

If you are comfortable with the command line, ADB (Android Debug Bridge will provide the most accurate data about the display, this method works on all Xiaomi devices, including those that are blocked engineering menus.

What you need:

• 🖥️ Computer with Windows/Linux/macOS.
• 📱 USB-cable (preferably original).
• 🔧 Established ADB Tools.
• ⚙️ Included debugging by USB phone-on.

Step-by-step:

1. Connect the phone to the PC and confirm access for debugging.
2. Open the command prompt (cmd on Windows) and type:

adb shell dumpsys display

In the conclusion, look for the DisplayDeviceInfo block. Example for the Mi 11 Lite:

DisplayDeviceInfo{




...


  name=qcom,mdss_dsi_samsung_amb655yv01_1080p_video


...




panelName=samsung,amb655yv01_cmd




...




}

Samsung here,amb655yv01_cmd — It's a matrix model.

Additional useful commands:

adb shell getprop | grep -i "panel"

(Shows system properties associated with the display)

adb shell cat /proc/cmdline

(Sometimes contains information about the display driver)

If the output is too large, save it to a file:

adb shell dumpsys display > display_info.txt

💡

ADB-The method is the most reliable way to get an accurate display model, but it requires minimal command line skills. ADB, Start with Method 1 or 3.

Method 5: Physical disassembly – 100% accuracy

If all the software methods don't work, the last option is to disassemble the device and look at the markings on the display plume, which is the only way to know the model, but it requires caution and tools.

What you'll need:

• 🔧 Set of screwdrivers (cross, flat, suction cup for the screen).
• 🧲 Plastic blades for disassembly.
• 📸 Hair dryer or heat station (to soften glue).
• 🔍 A magnifier or macro lens for a smartphone (marking is often small).

Step-by-step:

1. Turn off the phone and remove it. SIM-map.
2. Heat the edges of the screen with a hairdryer (temperature) ~60°C) for 2-3 minutes.
3. Carefully tuck the screen with a plastic spatula, starting at the bottom edge.
4. Disconnect the display plume (usually it is under a metal cover).
5. On the back of the plume or on the matrix itself, find the marking.

• 📱 SDC AMOLED E4 — Samsung E4 AMOLED.
• 📱 BOE NT37800 — BOE AMOLED mid-segment.
• 📱 Tianma FT8721 — frequent POCO.
• 📱 JDI TXD IPS — IPS-panels from Japan Display.

Typical marking locations:

⚠️ Note: When disassembling Xiaomi with AMOLED-Be very careful with the screens - the plumes of these matrices are thinner than those of IPS, If you've never taken a smartphone apart, you should ask the service center to "see the display model" (this takes 5 minutes and costs a lot of money). ~300 rubles).

If you are afraid of damaging the device, but want to see the plume, you can compromise:

1. Remove only the back cover (on most Xiaomi it is attached to the latches).
2. Keep the battery up (do not disconnect!)
3. Under it is often visible the plume of the display with markings.

💡

Before disassembling, take a picture of each step, which will help to properly assemble the phone back, especially remember the location of small plumes and screws (they often differ in length!).

Common Mistakes and How to Avoid Them

Even experienced users sometimes get it wrong when defining a display model, and we've collected some of the most common mistakes and ways to prevent them:

One of the most insidious mistakes is the confusion between the display model and the touchscreen model. For example, the Redmi Note 10 Pro can be installed on a Samsung matrix. E4, But a touchscreen from Goodix or FocalTech, and if you only order a screen, check if the touchscreen comes with it (often sold separately!).

Another pitfall is regional differences, such as the Xiaomi 12 Pro for the Chinese market often featured a Samsung display. E5, The global version was given BOE. If you are buying a used device, check the firmware region (Settings) → The phone. → Version. MIUI — if there is CN, It's the Chinese version).
