How to permanently remove the “Don’t close the speaker area” on Xiaomi: working methods 2026

The “Don’t close the speaker area”** on the Xiaomi, Redmi or POCO screen appears when the system captures the overhead speaker overlap – such as with a cover, finger, or when the device is improperly assembled after repair – a warning that protects the device from overheating and distortion of sound, but often interferes with users, especially if the speaker is not physically closed.

In this article, we will discuss 5 proven ways to remove the inscription – from simple settings in MIUI to editing system files through ADB. All methods have been tested on current versions of firmware (2023-2026) and are suitable for most models, from Redmi Note 10 to Xiaomi 13 Ultra. Importantly, some solutions require superuser rights or may affect the warranty – we will warn you about this in advance.

Why is the inscription appearing and can it be ignored?

The warning is triggered by a proximity sensor or a software algorithm in MIUI that analyzes:

• 🔊 Sound waves – if the speaker is muted (for example, lying on a soft surface).
• 📱 Light/approximation sensor – if the top of the screen is closed (case, hand).
• 🔧 Hardware errors - after falling or disassembling the device (the plume of the speaker departs).

You can only ignore a message if you're sure the speaker isn't physically closed, otherwise you're at risk of:

• 🔥 Overheating of the speaker (especially with loud music).
• 🎵 Sound distortion or failure of the membrane.
• 📉 Automatically reduce volume by the system.

⚠️ Warning: If the sign appears for no reason (speaker open, cover not), first check the device for hardware malfunctions.

Method 1: Disconnect via hidden MIUI settings (no root)

The safest method is to use the MIUI engineering menu, which works on most devices with MIUI 12-14 and does not require superuser rights.

Instructions:

1. Open the phone app and enter the combination: ##6484###
2. In the menu that appears, select the MBHC Test (or Audio → Speaker Test on some models).
3. Click Stop Test, then search for Speaker Obstruction Detection.
4. Switch it to the Disable position.
5. Save the changes and restart the device.

If the combination doesn’t work, try the alternative code:

##36446337##

Battery charge > 50%

All covers and tapes are off.

Checked that the speaker is not physically closed

Backup of important data is made

⚠️ Note: On some firmware (Xiaomi) EU, Custom assemblies) the engineering menu may be missing or have a different interface.

Method 2: Use of the ADB-Teams (for experienced users)

If the engineering menu is not available, you can turn off the speaker check via ADB (Android Debug Bridge), which requires a computer and enabled debugging over USB.

Step-by-step:

1. Download and install Google’s Platform Tools.
2. Turn on USB Debugging on your smartphone: Settings → About Phone → MIUI Version (click 7 times), then Settings → Additional → For Developers → Debugging over USB.
3. Connect your phone to your PC and type in the command line: adb shell settings put global speaker_obstruction_detection_enabled 0
4. Reset the device.

To get it back, use the command:

adb shell settings put global speaker_obstruction_detection_enabled 1

💡

If the command doesn't execute, try entering adb devices first to make sure the device is identified. If the list is blank, check the drivers or cable.

Method 3: Editing system files (root required)

For users with unlocked bootloader and root rights, a radical method is available - editing the build.prop file. This is the most reliable way to turn off the warning forever, but requires caution.

Instructions:

1. Install any file manager with root support (such as Root Explorer or Solid Explorer).
2. Go to /system/build.prop and open the file in the text editor.
3. Add the line at the end: persist.speaker.obstruction.detection=false
4. Save the changes, set the rights 644 (rw-r-----).
5. Reset the device.

If the inscription remains after the reboot, check:

• 🔄 The correctness of the path to the file (on some firmware it may be in the /vendor/build.prop).
• 📝 No typos in the added line.
• 🔧 Correct access rights (use chmod) 644 /system/build.prop Terminal Emulator).

⚠️ Warning: Incorrect editing of build.prop can lead to bootloop ( looped reboot!

Method 4: Disabling the proximity sensor (alternative)

Sometimes the message comes from a false alarm on the proximity sensor, and you can temporarily turn it off, but it will affect:

• 📞 Automatically shut down the screen during a call.
• 🔦 Signs (for example, lift to unlock).

How to turn it off:

1. Go to Settings → Screen → Approach Sensor.
2. Turn off the option to automatically turn off the screen.
3. Use the sensor to completely shut down ADB: adb shell settings put global proximity_sensor_enabled 0

To get it back:

adb shell settings put global proximity_sensor_enabled 1

💡

Turning off the proximity sensor is a temporary solution, and it can help diagnose a problem, but it doesn't eliminate the cause.

Method 5: Update or roll back firmware

On some versions of MIUI (especially 13.0.4-13.0.6), a dynamic warning appears due to a firmware bug.

• 🔄 Update to the latest stable version (via Settings) → Update of the PO).
• 🔙 Recoil on the previous build (if the bug appeared after the update).

How to check if the warning is related to the firmware:

1. Go to the Settings → About the phone → MIUI version.
2. Check the build number (e.g. V14.0.3.0.TKCCNXM).
3. Find out on forums (such as 4PDA or Xiaomi Community) bug information for your version.

What do you do if nothing helps?

If you’ve tried all the ways, but the “Don’t close the speaker area”** continues to appear, the reasons may be hardware:

• 🔧 Dynamic plume damaged - replacement is required (cost) ~1500–3000 ₽).
• 🎛️ Faulty proximity sensor - diagnosed in the service center.
• 🔊 Factory marriage dynamics - if the device is warranty, contact the store.

For self-diagnosis:

1. Call your phone and check if the screen turns off when you bring your hand to the top.
2. Turn on loud music and listen – if the sound is distorted for no apparent reason, the problem is the dynamics.
3. Try using your phone without a cover and film throughout the day.

⚠️ Warning: If you're not sure about your repair skills, don't disassemble the device yourself. IP-certification (for example, Xiaomi 13 Pro) disassembly without special tools can violate the tightness.

💡

Before visiting the service center, reset your phone to the factory settings (Settings → Reset). Sometimes this eliminates software failures that cause a false warning.
