How to permanently remove the words “Do not close the speaker area” on Xiaomi: working methods 2026

The message “Don’t close the speaker area” appears on Xiaomi, Redmi and POCO screens when talking on the phone if the system detects an overhead speaker overlap, most often when high-sided covers are used, the device is held incorrectly, or after the MIUI update. While the warning is designed to protect the sound, many users are hindered by it — especially when it pops up falsely.

In this article, we will discuss all the current ways to disable this notification, including official settings, ADB commands, system file editing and even hardware solutions. Each method is tested on MIUI 12-14 and is suitable for most models, from Redmi Note 10 to Xiaomi 13 Ultra. Important: some methods require unlocking the bootloader and can affect the warranty.

If you see this message all the time, the problem is not in your hands, but in the software or the proximity sensor, and we'll show you how to fix it without losing functionality.

Why does the inscription appear and whether it can be ignored?

The "Do not close the speaker area" warning is triggered when the proximity sensor detects an obstacle near the top of the screen. The MIUI system assumes that you have closed the speaker with your finger or cover, and tries to prevent sound deterioration.

✅ Faulty proximity sensor – especially after falls or moisture.

✅ High-sided cases – even Xiaomi’s original accessories sometimes block the sensor.

✅ Updates MIUI — in some versions (for example, MIUI 13.0.4) the algorithm for determining obstacles has become more aggressive.

✅ Film or glass covering the sensor – even transparent protections can interfere with its operation.

Can we ignore this message? Yes, but with reservations:

• 🔊 If the speaker is really blocked, the sound will be muffled, and the interlocutor may not hear you well.
• 📱 With prolonged neglect, the system can start automatically switching to speakerphone.
• ⚙️ In some models (for example, POCO F4) Frequent false positives cause the microphone to freeze.

If you are sure that the speaker is not closed and the message appears incorrectly, feel free to turn it off. Below we will explain how to do this as safely as possible.

Method 1: Disconnect via MIUI settings (without root)

The easiest method is to use hidden audio settings that are in MIUI but are not displayed in the main menu, which works on most devices with MIUI 12-14 and does not require superuser rights.

Instructions:

1. Open the phone application (standard call).
2. Dial the combination: ##36446337## (code for the proximity sensor test).
3. In the menu that appears, select “Proximity Sensor”.
4. Check the current value – if it is always “1” (even when nothing is closed by the speaker), the sensor is faulty.
5. Return to the main settings and go along the way: Settings → Special facilities → Improvement of sound → Disable “Closed Dynamic Warning» ⚠️ Note: Some firmware may call this item "Ignore speaker obstacles" or hide behind an additional menu. If it's not available, try the following method.

If the item is missing, then your version MIUI It doesn't support disconnection through the interface. ADB-command (method 2) or edit system files (method 4).

Check the version of MIUI in Settings → About the phone

Make sure the sensor is working correctly

Method 2: Disconnect via ADB (without root but with PC)

If you don’t have an option to turn off the warning, you can use Android Debug Bridge (ADB), which does not require root rights, but requires a computer and enabled USB debugging.

Step-by-step:

1. Enable “Debugging USB” on your phone: Settings → About Phone → MIUI Version (click 7 times) → Return to “Additional” → For Developers → Debugging by USB
2. Connect the phone to the PC and confirm the debugging permission.
3. Download ADB Tools and unpack into any folder.
4. Open the command line (Win) + R → cmd) and enter: adb shell settings put global proximity_sensor_ignore 1
5. Reboot the phone.

To get it back, use the command:

adb shell settings put global proximity_sensor_ignore 0

This method works on MIUI 12-14, but may reset after the system update. If the command does not work, try an alternative option:

adb shell settings put global proximity_delay 2500

(Increases the sensor response delay).

💡

If ADB does not recognize the device, install Xiaomi USB Drivers from the official website or through the Mi PC Suite.

Method 3: Calibration of the proximity sensor (if it is false)

Sometimes the problem isn't the warning itself, but the sensor is not working properly, and if it works even when the speaker is open, try recalibrating it.

How to do this:

• 📱 Enter the engineering code: ##6484## (on some models #36446337##).
• 🔧 Select “Proximity Sensor” and click “Calibrate».
• 📏 Follow the instructions on the screen – usually close and open the speaker several times.
• 🔄 Reboot the phone.

If the calibration didn't work, check the sensor for physical damage.

1. Light the flashlight on the top of the screen (near the speaker).
2. If the sensor (a small round hole) is contaminated, clean it gently with a soft brush or compressed air.
3. Check if the sensor plume is moving away (relevant after the screen is repaired).

On some models (e.g. Redmi Note 11), the proximity sensor is combined with the light sensor, so if after calibration the problem remains, you may need to replace the module.

Method 4: Editing system files (requires root)

For advanced users who are ready to get root rights, there is a radical method - editing the build.prop file. This will turn off the warning at the system level, but can cause unstable operation of some functions.

Instructions:

1. Get root with Magisk or TWRP.
2. Install a file manager with root support (such as Root Explorer).
3. Open the file on the path: /system/build.prop.
4. Add a line to the end of the file: persist.sys.proximity.ignore=true
5. Save the changes, set the 644 license and restart the phone.

Alternatively, disable the service responsible for warning:

pm disable com.android.server.telecom/com.android.server.telecom.settings.TelecomSettingsActivity

(introduced via ADB or Terminal Emulator with root rights)

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

Method 5: Hardware solutions (covers, film, repair)

If software methods have not helped or you don’t want to risk the stability of the system, consider physical ways to solve the problem:

✅ Change the case – many cases for Xiaomi have too high sides, overlapping the sensor. Choose a model with a cutout for the top speaker (for example, the original cases Xiaomi Smart Case).

✅ Slip sticker: If the sensor is too sensitive, stick a thin tape or special placer (sold in accessories stores) on the sensor area.

✅ Replace the proximity sensor -- if it's broken, it'll be replaced in 30-60 minutes at the service center:

• 📱 Redmi Note / POCO: 800–1 200 ₽
• 📱 Xiaomi 12/13 series: 1 500–2 000 ₽
• 📱 Flagships (Xiaomi 13 Ultra, Mix Fold): 2,500–3,500 ₽

✅ Disabling the sensor in the service center - some workshops offer software to deactivate the sensor without root, using special equipment.

If you decide to replace the sensor yourself, consider:

⚠️ Attention: On models with AMOLED-The proximity sensor is often soldered into the display module, replacing it requires a complete disassembly of the phone and costs more.

What to do if nothing helps

If you’ve tried all of these, but the message “Don’t close the speaker area” keeps popping up, perhaps the problem lies deeper:

🔹 Firmware conflict – some custom firmware (like Pixel Experience or LineageOS) may not process sensor signals correctly. MIUI.

🔹 The plume problem is that if you change the screen or fall, the plume connecting the sensor to the motherboard could be damaged.

🔹 Failure of the communication module is rare, but it happens that the warning is not caused by the sensor, but by an error in the Telecom module. In this case, resetting to factory settings will help (don't forget to make a backup!).

If the phone is warranty, don’t try to repair it yourself – contact the official Xiaomi service center. In most cases, the replacement of the sensor or diagnostics will be performed free of charge.

💡

Before visiting the service center, reset your phone to the factory settings (Settings → Reset) to eliminate software causes of the problem and speed up repairs.
