The “Don’t close the speaker area” on the Xiaomi Redmi screen comes up unexpectedly and annoys many users. It blocks part of the interface, interferes with games, watching videos and even normal smartphone use. In most cases, this is not a system error, but a protective mechanism that works when you detect obstacles in front of the speaker (dust, cover, fingers).
In this article, we will analyze all possible ways to remove the inscription - from the official (through settings and updates) to hidden (using the engineering menu and the slate). ADB). We also explain why methods like “just wipe the speaker” don’t always work, and what risks radical solutions carry. 10/11/12 Pro, Redmi 9/10/13C, POCO X3/X4 and other devices based on MIUI 12–14.
Why does the inscription appear and what does it mean?
The "Do not close the speaker area" warning is part of the Smart PA (Power Amplifier) technology that protects the speaker from overheating and damage.
- 📊 Approximation/light sensors – sometimes falsely triggered (for example, due to dirty glass or a magnet case).
On Redmi Note 11 Pro+ and later, the system can block the sound completely if it detects a critical obstacle. On older devices (e.g. Redmi 9A), the warning often appears due to poor calibration of sensors after MIUI updates.
Official ways to remove the inscription (without risks)
Before you resort to radical methods, try standard solutions, which don't require root rights or technical skills:
- Reboot your smartphone. Sometimes the alert is a temporary failure. Hold the power button for 10 seconds to force the device to restart.
- Clean the speaker and sensors. Wipe the top of the screen (where the speaker is) with an alcohol wipe. Use a toothpick or soft brush to remove dust from the grille.
- Removal of the case. Magnets or thick material may interfere with the sensors. Check if the inscription disappears without the cover.
- Update MIUI. Go to Settings → About Phone → System Update. In some firmware versions, the bug has been fixed (for example, in MIUI 14.0.4 for the Redmi Note 12).
If the problem persists, check the sound settings:
- 🎵 Open the Settings. → Sound and vibration → Sound quality.
- 🔇 Turn off the “Amprovement of Sound” option (if any) – it can cause false positives.
- 📱 Turn on No Sound mode for 10 seconds, then turn the sound back on.
☑️ Checklist before radical methods
Hidden settings: engineering menu and sensor tests
If standard methods didn't work, the reason could be that the proximity sensor or the light sensor is not working properly, and you can check them through the engineering menu.
- Open the Phone app and enter the code ##6484## (some models run ##4636## → Equipment Testing).
- Select the "Proximity Sensor" option.
- Put a flashlight on top of the screen (where the sensor is located). The value should change from 5 (close) to 0 (far). If it shows 5 constantly, the sensor is contaminated or defective.
To reset the sensor calibration:
- 🔧 In the engineering menu, select Sensor Calibration».
- 🔄 Press Reset for Proximity Sensor).
- 📱 Reboot your smartphone.

ADB-Commands: Disabling the Warning via PC
If the message appears due to a software failure, it can be disabled via Android Debug Bridge (ADB).
- 💻 Computer with installed Xiaomi and ADB-tools drivers.
- 🔌 USB-cable (preferably original).
- 📱 On your smartphone, turn on Settings → The phone. → Version. MIUI (Press 7 times to activate Developer Mode, then in Settings → Additionally. → For developers, include “Debugging by” USB».
Next, execute commands in the terminal (PC command line):
adb shell
settings put global dynamic_speaker_warning 0If the command fails, try the alternative (for MIUI 13+):
adb shell
am broadcast -a android.intent.action.CLOSE_SYSTEM_DIALOGS💡
After completion ADB-commands to restart your smartphone if it comes back after the update MIUI, repeat the procedure.
Risks and consequences of disabling the warning
Before removing the inscription by radical methods, consider possible problems:
| Method | Risks. | Effects of consequences |
|---|---|---|
| ADB-team | Low. | It may be reset after the MIUI update. |
| Engineering menu | Average. | Incorrect calibration of sensors will lead to constant failures. |
| Root + Delete System Files | Tall. | Loss of warranty, possible brick (inoperability) of the device. |
| Physical cleaning dynamics | Minimum | The risk of damaging the membrane of the speaker with careless actions. |
⚠️ Note: If you are using Redmi with a Snapdragon processor (such as the Redmi Note 10 Pro), disable the warning via the Snapdragon processor. ADB This can cause the speaker to overheat when playing long-term sound. On models with MediaTek (e.g. Redmi) 10C) The risk is lower, but it remains.
What to do if nothing helps
If the words “Do not close the speaker area” appear even after all the manipulations, it is possible:
- 🛠️ Hardware malfunction: Intending sensor or speaker is damaged. Solution: Replacement at the service center (cost) ~1 500–3 000 ₽).
- 🔄 Firmware conflict - especially after updating via Fastboot.Solution: rollback to stable version MIUI.
- 🦠 Viral software - some applications (such as "sound amplifiers" from unverified sources) can mimic system alerts.
To diagnose hardware problems:
- Run the equipment test using the code ##4636## → “Equipment Testing”.
- Check the speaker in Settings → Sound → Dynamic Test.
- If the sound is distorted or absent, the malfunction is physical.
💡
If your smartphone is warranty, do not use ADB or root methods. contact Xiaomi Service Center – according to the Consumer Protection Act (Article 18), repairs must be free, unless the defect is caused by mechanical damage.
