How to remove the extra screen on Xiaomi: from software failures to hardware repair

The problem with the overscreen on Xiaomi smartphones is one of the most common malfunctions faced by brand users, which is most often referred to as a black screen (the device works, but the image is missing), a white screen (there is a backlight, but there is no picture), or a repetitive logo when loading. In 80% of cases, software failures are to blame, but sometimes it is hardware failures — from a departed plume to a damaged display.

If your Redmi, POCO, or Mi suddenly stop showing an image, don’t rush to take it to the service center. In this article, we’ll look at all possible causes and solutions, from the simplest restart to flashing through Fastboot. Importantly, some techniques require technical skills, so read the warnings carefully before you act.

Before you start the repair, answer two key questions:

1. Does the phone react to charging (the indicator burns, vibrates when connected)?
2. Are there any warnings or can you make a blind call?

If the answer is yes to one point, it's more of a software problem, and if both answers are no, maybe the battery or the motherboard has failed.

1.The reasons for the appearance of the “extra” screen on Xiaomi

Xiaomi users often use the term “extra screen” to describe three types of malfunctions:

• 📵 Black screen – the phone turns on (vibrates, makes sounds), but the display does not show the image.
• ⚪ White screen – backlight works, but instead of the interface, a uniform white screensaver is visible.
• 🔄 Loaded Loading – The device is constantly restarted or hangs on the logo Mi/POCO.

The main causes of these problems are divided into software and hardware:

🔹 The most common reason for black screen on Xiaomi is a failure in the display driver after an update. For example, users of the Redmi Note 10 Pro massively complained about this problem after upgrading to the new device. MIUI 14 in 2023.In such cases, a reset via Recovery or flashing helps.

⚠️ Warning: If the screen turns black after a fall or impact, do not try to solve the problem programmatically. Most likely, the plume has moved or the matrix has cracked - you need to disassemble the device.

2. Software methods of eliminating excess screen

Start with the simplest methods – they work 60% of the time and don’t require technical skills.

Forced reset

If the phone is stuck on the logo or the screen is black after the update, try the hard reset:

1. Press the Power + Volume button for 10-15 seconds.
2. Wait for the vibration or the appearance of the Mi logo.
3. Release the buttons and wait 1-2 minutes.

🔹 In some models (for example, POCO F3) The combination may be different: Nutrition + Turning down the volume.

2.2 Reset via Recovery Mode

If the phone is turned on but the screen is not working, try resetting your settings via Recovery:

1. Turn off the device (press the power for 20 seconds).
2. Press Power + Volume Up until the Recovery menu appears.
3. Use volume buttons to navigate, select Wipe Data → Wipe All Data.
4. Confirm the action and wait for the reboot.

⚠️ Warning: This method will delete all data from the device. If the phone had important files, first try connecting to the PC via the device. ADB (see section 4).

2.3 Update via Fastboot

If the reset didn't work, but the phone is determined by the computer, try flashing it over the Fastboot.

1. Download the official firmware for your model from the MIUI Download website.
2. Unpack the archive and launch the file flash_all.bat (Windows).
3. Connect your phone in Fastboot mode (clip Power + Volume Reduction).
4. Wait until the process is completed (5-10 minutes).

🔹 On models with a locked bootloader (for example, Xiaomi) 12T) Before the firmware you need to unlock Bootloader through the official application Mi Unlock.

Install ADB and Fastboot drivers on PC|

Charge your phone at least 50% |

Disable antivirus (can block firmware scripts)|

Hardware solutions

If the software didn't work, the problem is probably hardware. Let's look at the most likely scenarios.

Checking the display plume

A black or flashing screen often results from a broken plume connecting the matrix to the motherboard, a typical problem after a phone falls or disassembles.

1. Carefully remove the back cover (need a mediator and a hair dryer to soften the glue).
2. Disconnect the battery (required!).
3. Find the display plume (usually located at the top of the board) and check if it is pressed tightly.
4. If necessary, reconnect it and fix it with tape.

⚠️ Warning: Do not touch the plume contacts with your bare hands - static electricity can damage the chips. Use an antistatic bracelet or gloves.

Diagnostics of the matrix

If the screen is white or with artifacts (bands, broken pixels), the problem may be in the matrix itself.

1. Connect your phone to an external monitor via USB-C → HDMI adapter.
2. If the external screen image is normal – the matrix of the phone is to blame.
3. If the artifacts remain, the problem is in the graphics chip or plume.

🔹 On models POCO X3 The Pro and Redmi Note 11 often fail the backlight controller – in this case, the screen will be dim or completely black, but in bright light you can see the image.

Checking of the battery and the power controller

If the phone doesn’t respond to charging and doesn’t turn on, the problem may be:

• 🔋 Bloated or swollen battery (replacement needed).
• 🔌 Faulty power controller (requires soldering).
• 🔌 Damaged. USB-port (check if there is any debris or oxidation inside).

🔹 To check the battery, connect your phone to charge and listen – if you hear a slight hissing, but the indicator does not burn, most likely, the problem in the controller.

4.Dealing with ADB: Data Recovery and Diagnostics

If the screen is not working, but the phone is determined by the computer, you can try to extract data or execute commands through ADB (Android Debug Bridge).

Connect to a PC in blindness

To turn on USB-debugging:

1. Connect the phone to the PC.
2. Press Power + Volume Up to Enter Recovery.
3. In the recovery menu, select Connect with MIAssistant (navigation with volume buttons).
4. On PC, run Mi PC Suite and watch for connection.

4.2. the main ADB teams

If ADB is connected, you can perform a diagnosis:

adb devices

- check the connection.

adb shell dumpsys power

Display status (see mScreenOn=true/false)

adb pull /sdcard/

Copy files from phone to PC.

⚠️ Note: If the phone is not detected in ADB, but responds to charging, try using Fastboot: fastboot devices If the device is displayed, you can flash it around the screen.

💡

If the phone vibrates when connected to charging but doesn't turn on, try pinching Power + Volume Reduction for 30 seconds - this sometimes resets the power controller and lets the device start.

5. When to contact the service center

Not all problems can be solved by yourself. Contact the service if:

• 🛠️ The phone does not respond to all software methods (reset, firmware, ADB).
• 💥 The screen is physically damaged (cracks, dents, fluid drips).
• ⚡ After the fall, other functions (camera, speaker, sensors) stopped working).
• 🔥 Phone warms, smells of smoke or battery swollen.

💡

If the phone is warranty, don't disassemble it yourself! opening the case will void Xiaomi's warranty obligations.

6. Prevention of screen problems

To avoid repeated failures, follow these guidelines:

• 📲 Update regularly MIUI, Do not install beta versions on the main device.
• 🔋 Avoid full battery discharge (keep the charge at 20–80%).
• 🛡️ Use depreciation covers when hitting.
• 🚫 Do not install apps from unverified sources (they may conflict with display drivers).

🔹 On the Redmi models and POCO s AMOLED-screens (e.g. Redmi) K50) Avoid long-term display of static images – this can cause pixels to burn out.

💡

If the screen starts flashing or twitching after the MIUI update, roll back to the previous firmware version via Fastboot. Often bugs are fixed in the following patches.
