How to accurately determine the screen model on the Xiaomi smartphone: from the box to the service menu

Are you trying to replace a broken screen on Xiaomi, but you don't know which one to order? Or want to check the originality of the display after repair? Determining the exact screen model is a critical step, on which compatibility, image quality and even sensor performance depend. In this article, we will discuss 7 working methods, including hidden service menus, box analysis and visual features that will help identify the display even without disassembling the device.

The problem is that Xiaomi (and other manufacturers) often use different matrix vendors for the same smartphone model. For example, the Redmi Note 10 Pro could be equipped with screens from Samsung AMOLED, BOE or Tianma — all of which are visually almost indistinguishable. A mistake in choosing will lead to problems with color reproduction, autobrightness or even complete inoperability of the touch screen.

1. Check the screen model through the smartphone settings

The easiest way is to use the built-in MIUI tools, which don't always give you an exact matrix model, but it can help you identify the display manufacturer and the type (AMOLED/IPS).

1. Open the Settings app → The phone.
2. Tap the MIUI version several times until the message “You’ve become a developer!” appears.
3. Return to the main settings menu and select Additional → For developers.
4. Find the Equipment section and open the Display Information.

You'll see data like the Display Panel here: samsung_amb655uv01 or BOE NT37800. The first part before the emphasis is the matrix manufacturer (Samsung, BOE, Tianma et al.), and the second is the internal designation of the model, if this menu only displays the screen resolution (for example, the screen resolution, 1080×2400), So your firmware doesn’t support the output of detailed information – move on to other methods.

💡

If the Developer section is missing, check the MIUI version. On some older firmware (below MIUI 12), this method does not work. Update the system or use alternative methods.

2. Service codes for display diagnostics

Hidden engineering menus provide technical screen data that is not displayed in standard settings, which work on most Xiaomi, Redmi and POCO devices, but may vary depending on the model and firmware region.

Enter the following combinations in the Phone application:

• 🔢 ##3644633## - Display test (shows manufacturer and matrix model at the top of the screen).
• 🔢 ##4636## → Phone information → Scroll down to the Display block.
• 🔢 ##284## - Sensor test (can display data about the touch panel, which often comes with a matrix).

In the ##3644633## menu, look for the Panel ID or Display IC bar. For example, the NT36672C value indicates the Novatek matrix, and the AMS643JE01 value indicates the Samsung AMOLED. If the code doesn't work, try typing it without stars: 3644633.

3. Visual identification by box and documents

If you still have the original smartphone box, it might have display information on it.

• 📦 The article of the model (e.g, M2007J3SC It's the screen specs you can find on sites like GSMArena or mi.com.
• 🏷️ Serial number sticker (usually at the bottom of the box) sometimes shows the display manufacturer (e.g., the manufacturer of the display, SAMSUNG DISPLAY).
• 📄 Warranty card: In some regions (e.g. India, China) parts are prescribed in the documents.

Also, look for the color labels on the box or battery sticker (if the phone is already disassembled), for example, the Xiaomi Mi 11 matrices from Samsung were marked with green bar, and from BOE - blue, this information is often discussed on forums like 4PDA or XDA Developers.

Disassembly of the device: where to look for screen marking

If the software methods don't work, you'll have to take a partial disassembly of the smartphone, and you'll notice that this cancels the warranty (if it's still valid) and you need to be careful not to damage the plumes.

Turn off the phone and remove it. SIM-map

Prepare a plastic blade and a T3/T4 screwdriver

Warm the back cover with a hairdryer (temperature not higher than 60 ° C)

Take a picture of the location of the plumes before disconnecting-->

After the back cover is removed:

1. Disconnect the battery (required!) to avoid short circuit.
2. Carefully disconnect the display plume from the motherboard.
3. On the back of the matrix, look for a labeled sticker, which is usually located in one of the corners and contains data like: BOE NV116FHM-N40 2021.05.15 L11M003

Decoding of markings:

• 🔤 BOE/NV116FHM-N40 — manufacturer and matrix model (the main thing you need to order a replacement).
• 📅 2021.05.15 – Production date (useful for authentication).
• 🆔 L11M003 — internal batch code (may differ for one screen model).

💡

If there's no sticker on the matrix, try looking for an engraving on the metal frame of the screen or the plume, and sometimes the data is lasered and visible under the magnifying glass.

5. Use of third-party applications

Several apps from Google Play can pull technical screen data that standard firmware doesn't show.

In AIDA64, go to Display and notice the following fields:

• 📱 Display ID — unique matrix identifier.
• 🔧 Driver IC — display controller model (e.g, NT36672A).
• 🎨 Technology - type of screen (AMOLED, IPS LCD etc.).

💡

If the app only shows a piece of data (e.g., only the manufacturer), try running it in developer mode with USB debugging enabled, which sometimes reveals hidden settings.

6. Determination by external features and behavior of the screen

If none of the above methods worked, you can try to identify the matrix by indirect signs:

• 🌈 Color rendering: Samsung screens AMOLED They have more color and a deeper black. BOE Tianma and Tianma often give a cool hue and less contrasting colors.
• ☀️ Autobrightness: Samsung smoothly adjusts brightness without jerks. BOE may twitch when changing lighting.
• 🔍 Viewing angle: AMOLED-screens do not lose color when viewed from an angle. IPS-Matrices (e.g. in budget Redmi) may fade".
• 📏 The Xiaomi Mi 11 matrix from Samsung have thinner bezels than the one in the box BOE.

You can also test the memory effect (burn-in):

1. Open a monochromatic image (such as a white screen) at maximum brightness.
2. Look at it from an angle – if you can see traces of previous images (like navigation bars), it’s AMOLED.

💡

If your smartphone supports your mode DC Dimming (in screen settings), most likely it has a matrix from Samsung or BOE This is a regime that is not in most of the world. IPS-display.

7. appeal to the service center or to the seller

If independent methods have not yielded results, there are two reliable options:

1. Official Xiaomi service: 📞 By telephone hotline, for example, 8 800 775-66-22 For Russia, name the model of the smartphone and the serial number – they can specify the data by database. 🏢 In the service center, the matrix is identified using professional equipment (for example, CCTester).

Parts vendor

• 🛒 On sites like AliExpress or ETrade Supply, specify the phone model – the description often writes compatible matrixes.
• 💬 In a chat with the seller send photos of stickers from the back cover or box - they will select the right screen.

⚠️ Note: When ordering a matrix, specify not only the model, but also the revision (for example, Redmi Note 8 Pro). V1 vs V2). Even in one series, screens can differ in plume connectors!

Also check if it comes with a touchscreen array (touch layer). In some models (for example, the POCO X3 NFC), the screen and touchscreen are separate parts and you need to buy them together.
