How to remove the inscription “Do not close the speaker” on Xiaomi: all ways

The words “Don’t close the speaker”** appear on the screen of Xiaomi, Redmi or POCO when the system detects overheating or blocking of acoustic holes, most often when listening to music through an external speaker, while playing games or when using the device in a horizontal position (for example, lying on its side). Although the warning is designed to protect the device from damage, many users consider it intrusive — especially if it pops up without a real threat.

In this article, we will look at 5 proven ways to disable a message, from standard MIUI settings to hidden engineering menus. Importantly, some methods require unlocking the bootloader or root rights, which can affect the warranty. We will outline the risks for each option and explain in detail how to proceed safely. If you are the owner of a Xiaomi 13/14, Redmi Note 12 or POCO F5 model, the instructions are relevant for you.

Why is there a warning “Do not close the speaker”?

The message works for three main reasons, and understanding the mechanism will help you choose the right way to turn off:

• 🔥 Overheating speaker. The system detects a temperature rise above 50-55°C (threshold depends on model) This can occur when sound is played at maximum volume or in a hot room for a long time.
• 🚫 Physical lock: If the speaker is covered by a hand, cover or surface (for example, when the phone is lying down the screen), pressure sensors or microphone register the obstacle.
• 🤖 Sometimes the warning is due to firmware errors, especially after the update. MIUI or custom-themed settings.

On Xiaomi models with stereo speakers (such as the Xiaomi 12 Pro or Redmi K60), the message can be duplicated for each speaker separately. In rare cases, a defect in the Hall sensor is responsible for determining the position of the device in space. If the sensor is faulty, the system mistakenly “thinks” that the speaker is closed.

Method 1: Disconnect via sound settings (without root)

The easiest method is to use hidden options in the Sound and Vibration menu.** It works on most devices with MIUI 12-14 and does not require additional permissions.

1. Open the Settings. → Sound and vibration.
2. Scroll down and select Additional settings.
3. Click on Security Speaker (on some firmware, the item may be called Protection Speaker).
4. Turn off the speaker lock warning.

If there is no safety speaker, try an alternative path:

Settings → Special features → Sound settings → Disable “Dynamism Warnings”

Check out the MIUI version (Relevant for MIUI 12 and later)

Make sure the speakers are not covered with a cover

Reboot your phone before changing your settings

Make a backup copy of sound profiles-->

Method limitation: On some models (e.g. POCO X5 Pro), this item may be blocked by the manufacturer, in which case move on to the next method.

Method 2: Resetting the sound settings to the factory

If the alert comes after you update your MIUI or install third-party apps (e.g. equalizers), resetting your audio settings will help, not delete your files, but will bring all volume, notification and alarm settings back to the “out of the box” state.

How to reset:

1. Go to Settings → Applications → Application Management.
2. In the upper right corner, click on three dots and select Reset application settings.
3. In the list, find the Sound Settings (or Audio Settings) and confirm the reset.

⚠️ Warning: Check the speakers at maximum volume after reset. If the warning is gone but the sound is quieter, manually return the Dolby Atmos or Equalizer settings.

Method 3: Use of the Engineering Menu (MTK/Qualcomm)

For advanced users, there is a method through an engineering menu. It is suitable for devices on MediaTek chips (Redmi 10C, POCO M5) and Qualcomm (Xiaomi 12, Redmi K50). On models with a Snapdragon 8 Gen 2 processor (for example, Xiaomi 13 Ultra), this method can cause the sound driver to crash - use with caution.

Instructions for MediaTek:

1. Open the Phone app and enter the combination: ##36446337###.
2. Go to the Hardware Testing → Audio section.
3. Select Speaker Test and turn off Speaker Protection.

For Qualcomm:

1. Enter the phone app: ##4636###.
2. Select Information → Audio.
3. Find Speaker Safety and set the Disabled value.

⚠️ Warning: Changes to the engineering menu may disrupt microphones or speakers. Press Restore Default before leaving the menu if the sound is gone or distortions appear.

Method 4: Disconnect via ADB (for power users)

If previous methods have not worked, you can use them. ADB-It requires connecting the phone to the computer and enabling debugging. USB. The method is universal for all Xiaomi models on Android 10–14.

Step-by-step:

1. Download and install Google’s Platform Tools.
2. On your phone, turn on Settings → About Phone → MIUI version (click 7 times to activate Developer Mode).
3. Return to Settings → Additional → For developers and enable USB debugging.
4. Connect your phone to your PC and type in the command line: adb devices (your device should appear).
5. Execute the command to disable the warning: adb shell settings put global speaker_protection_enabled 0

To return the settings back, use:

adb shell settings put global speaker_protection_enabled 1

1. Install Xiaomi USB Drivers drivers manually.

2. switch the connection mode to File Transfer (MTP).

3. Use the original USB-cable (not all cables support debugging).-->

Method 5: Editing System Files (requires root)

The most radical method is to delete the system file responsible for the warning, which is only suitable for users with unlocked bootloader and root rights. On devices with MIUI 14 and later, this method can cause a system integrity check (DM-Verity) error - be prepared for possible flashing.

How to remove the warning:

1. Install a file manager with root support (such as Root Explorer or Solid Explorer).
2. Go to /system/media/audio/notifications/
3. Find the file. speaker_obstruction.wav (or speaker_warning.mp3) and rename it in speaker_obstruction.bak.
4. Reset the device.

Alternatively, edit the file. audio_policy_configuration.xml file /vendor/etc/, line-out:

<speaker_protection enabled="true" />

⚠️ Note: After editing system files may stop working OTA-Update. Before the next update, return the original files or manually run the firmware through Fastboot.

💡

If you are not sure about your root skills, you should use methods 1-3. Incorrect editing of system files can lead to a device blink (complete failure).

What do you do if nothing helps?

If none of the methods has fixed the problem, the reasons may be hardware:

• 🛠️ Contamination speaker. Dust or moisture inside the grille can cause false alarms. Try to clean the speaker carefully with compressed air or a soft brush.
• 🔧 Hall sensor malfunction: On infrared port models (like the Redmi Note 9 Pro), the sensor can fail.
• 🔊 If the warning is accompanied by a distortion of the sound, it may be necessary to replace the audio module.

To diagnose hardware problems:

1. Run the speaker test through the Mi Check app (available from the Mi App Store).
2. Check if the alert appears in safe mode (press the power button → Safe Mode). If not, it is the fault of third-party software.
3. Reset your phone to factory settings (don’t forget to make a backup!).

If the warranty is still valid, contact the Xiaomi service center. the warning "Do not close the speaker" is officially considered a malfunction if it appears without objective reasons (for example, at normal temperature and open speakers).
