How to accurately find out the display model on Android: from system settings to disassembly

The smartphone screen is one of the most vulnerable and expensive components, and its replacement or repair requires precise knowledge of the model. But manufacturers rarely indicate this information in plain sight: you will not find matrix markings either in the box or in the documentation. Meanwhile, incorrectly selected display can lead to problems with color calibration, a non-working touchscreen, or even damage to the motherboard.

In this article we will look all working methodshow to find the display model on an Android device - from simple (through system settings) to complex ones (disassembling the phone). The methods have been tested on smartphones Samsung, Xiaomi, Honor, Realme and other brands. Important: some methods require root access or special applications, but we will indicate where you can do without them.

1. Checking through the Android system settings

The safest and fastest method is to search for information in the smartphone menu. Unfortunately, not all manufacturers provide detailed information about the display, but it’s worth a try.

Open Settings → About phone → General information (the path may differ depending on the shell). Look for sections like:

• 📱 Device model —the screen type is sometimes indicated here (for example, AMOLED or IPS LCD).
• 🔍 Version kernel —in rare cases it contains a mention of the matrix manufacturer (for example, Samsung Display or BOE).
• 📊 Battery status —on some Xiaomi information about the display is displayed here.

On Samsung s One UI go to Settings → Device care → Diagnostics and run a screen test. In some models (for example, Galaxy S22) after the test, a window appears with technical data, including the matrix manufacturer.

⚠️ Attention: On smartphones with MediaTekprocessors (many models Redmi, Realme), system settings often hide information about the display. In this case, proceed to the following. methods.

2. Using the engineering menu (codes and applications)

The engineering menu is a hidden section of Android where low-level data about hardware components is stored. It can be accessed through secret. codes or specialized utilities.

The most common codes for entry:

• 📞 ##4636## —a universal code for most Android devices (section "Phone Information").
• 📱 #0# —display test for Samsung (shows color tests, but not always the matrix model).
• 🔧 ##36446337## —engineering menu on some Xiaomi and Redmi.

If the codes do not work, install the application MTK Engineering Mode (for MediaTek) or Phone INFO ★Samsung★ (for Samsung Exynos/Snapdragon). In these utilities, look for sections:

• 🖥️ Hardware Info → Display —the matrix model may be indicated here (for example, SDC AMOLED for Samsung Display).
• 📡 RF Band Info —sometimes contains data about the screen manufacturer.

On Samsung with a processor Exynos try the application Exynos Info —it shows detailed information about the display, including serial number of the matrix and the manufacturer.

⚠️ Attention: Do not change the settings in the engineering menu if you are not sure of their purpose! Incorrect parameters can lead to loss of screen calibration or even “brick” of the device.

3. Analysis via ADB (for advanced users). users)

If you have a computer and a little experience with ADB (Android Debug Bridge), you can extract display data directly from the system. This method works even without root access.

Enable USB debugging in the settings first. developer, then connect the smartphone to the PC and execute in the command line:

adb shell dumpsys display

In the output, look for lines with:

• 🔹 mDisplayId — display identifier.
• 🔹 mManufacturer —matrix manufacturer (for example, samsung, boe, tianma).
• 🔹 mModel — display model (if specified).

For more detailed information, use the command:

adb shell cat /proc/panel_info

This command works on many smartphones with processors Qualcomm (for example, OnePlus, Xiaomi on Snapdragon).

What what to do if ADB does not show the display model?

If the command returns empty output or error, try:

1. Use adb shell getprop ro.boot.display (on some Xiaomi).

2. Install Magisk and module Panel Info for extended data.

3. Check the output after a reboot - sometimes the data does not appear immediately.

4. Physical inspection of the display (disassembly)

If the software methods do not work, all that remains is disassemble the smartphone to look at the markings on the screen itself. This is an extreme method, as it requires care and the risk of damaging the cables.

What you will need:

• 🔧 Plastic spatula or pick for opening the case.
• 🔥 Hair dryer (to soften the glue on the screen).
• 📸 Magnifying glass or smartphone macro lens for reading small text.

Action algorithm:

1. Turn off the phone and remove the back cover (on some models you will need to disconnect the battery).
2. Carefully pry up the screen around the perimeter, pre-heating the glue with a hairdryer (temperature no higher than 60°C!).
3. Look for a sticker with markings on the back of the display or on the flexible cable. It usually starts with:

Manufacturer	Example of marking	Used in smartphones
Samsung Display	AMS643JK01, EO643	Galaxy S21, Galaxy A52
BOE (Jing East)	NT36672C, FHD+ BOE	Redmi Note 10, Realme 8
Tianma	TM FT8719, NT36525	Poco X3, Honor 50
LG Display	LGD JDI, HX630	Google Pixel 6, LG Velvet

⚠️ Attention: Disassembling the smartphone voids the warranty can lead to damage to the display or cables. If you are not confident in your skills, contact the service center.

5. Online services and databases

If you know the exact model of the smartphone, you can find information about the display in open databases. Here are the most reliable sources:

• 🌐 GSMArena - the device characteristics sometimes indicate the type of matrix (for example, Super AMOLED or IPS LCD).
• 📊 NotebookCheck —detailed reviews of smartphones with information about the display manufacturer.
• 🔍 Panelook —a database of matrices where you can find a model by number (for example, AMS643JK01).
• 🛠️ iFixit —spare parts models are often indicated in repair guides.

Search example:

1. Find on the box or in the settings exact smartphone model (for example, Redmi Note 11 Pro 5G (veux)).
2. Enter the query in Google: Redmi Note 11 Pro 5G display panel model site:gsmarena.com.
3. Check sections "Display" or "Screen" in the results.

For Samsung the service Samsung Members (application) is useful: in the "Diagnostics" → "Screen Test" section, the matrix manufacturer is sometimes displayed.

Specify the full name of the smartphone model (with code name)

Check GSMArena and NotebookCheck

6. Contacting a service center or seller

If all the previous methods did not work, there remains consultation with specialists. Here is where you can get accurate information:

• 🏠 Official service center - they can tell which display is by the serial number of the device. installed. Samsung i Xiaomi have online support chats.
• 🛒 The store where you bought it smartphone - if the phone is new, the seller may have information about the components.
• 🔧 Unofficial workshops —many repairmen have databases of compatible matrices for popular models.

When contacting, please specify:

• 📌 Serial number (IMEI) smartphone.
• 📌 Date of purchase (in case the display is replaced under warranty).
• 📌 Reason for the request (repair, replacement, verification of originality).

For example, in Samsung on IMEI you can find out which display was installed at the factory, and in Xiaomi - check whether was the matrix replaced under warranty.

⚠️ Attention: In unofficial workshops they may tell you the display model “from memory” or from appearance. Always ask to see original matrix for comparison or documentation.

FAQ: Frequently asked questions about Android display models

Is it possible to find out the display model without disassembling the smartphone?

Yes, in most cases. Try:

1. Engineering menu (codes ##4636## or #0#).
2. Applications like Phone INFO ★Samsung★ or DevCheck.
3. ADB commands (adb shell dumpsys display).

Only if these methods did not work, resort to disassembly.

How to distinguish an original display from a fake?

Signs of a non-original matrix:

• 🔹 Colors look duller or have a greenish/blue tint.
• 🔹 Brightness is lower than stated (for example, instead of 800 nits - 400 nits).
• 🔹 The touchscreen works with delays or “misses” touches.
• 🔹 The sticker on the cable does not match the original one (for example, instead Samsung Display — Unknown).

To check, use tests in Display Tester (Android application).

Why can there be different displays on the same smartphone?

Manufacturers often order matrices from several suppliers. For example:

• Samsung Galaxy S23 may have a screen. from Samsung Display or BOE.
• Xiaomi Redmi Note 12 equipped with displays Tianma or Visionox.

This is normal practice, but the quality may vary (for example, BOE is often criticized for worse color rendition compared to Samsung Display).

Where to buy an original matrix for replacement?

Official sources:

• 🏢 Manufacturer service centers (the most reliable option).
• 🌍 Sites like AliExpress (look for sellers with a rating above 98% and reviews of compatibility).
• 🛒 Spare parts stores (for example, ETK, MobileDefender).

Before purchasing, check:

• 🔹 Matrix model (must match up to the last character).
