Owners of Xiaomi Redmi Note smartphones (especially Redmi Note 10/11/12 series models) often face an annoying notification: โDonโt close the speaker area.โ The message appears even when the speaker is not closed, interferes with listening to music, speakerphone conversations and using multimedia. What is the reason for this bug, why the system mistakenly detects the speaker lock โ and most importantly, how to turn off the function forever without risk to the device?
In this article, weโll look at all the ways to solve the problem, from simple audio settings to deep changes in system files (for advanced users), and explain why turning off the proximity sensor or resetting doesnโt always help, and which Redmi Note models are most susceptible to this bug. If youโre tired of constant pop-ups and want to return comfortable use of your smartphone, read on.
Why does the warning โDonโt close the speaker areaโ appear?
The message "Do not close the speaker area" is a MIUI security function that works when the detects system locks the speaker (for example, with your palm, case or fingers).
- ๐ Overheating of the speaker with prolonged sound reproduction in a closed state;
- ๐ต Sound distortion due to resonance in a confined space;
- ๐ต Drop in microphone volume during calls (if the speaker is closed by hand).
However, in practice, Xiaomi Redmi Note sensors often give false positives.
- Pollution of the proximity sensor (dust, greasy fingerprints);
- Damage to the plume after falling or repairing;
- Software bug in MIUI (especially in versions 12-14)
- Incompatibility of covers with a cutout under the speaker.
Interestingly, the problem is more common on models with stereo speakers (Redmi Note 10 Pro, Note 11S, Note 12 Pro+), where the system analyzes the operation of both speakers. If one of them is partially closed (for example, with a finger while horizontally holding), an alert is triggered.
Simple ways to remove notifications (without root)
Before resorting to radical measures, try safe methods that do not require superuser rights:
1. Cleaning of the proximity sensor
Most often, the problem is solved by a simple cleaning, the sensor is located next to the front camera (top of the screen).
- ๐งด Wipe the area with a cotton swab soaked in alcohol (60% and higher);
- ๐จ Use a spray of compressed air to remove dust;
- ๐ฑ Reboot your smartphone after cleaning.
2. disable notifications in sound settings
In some versions of MIUI, the warning can be disabled via the menu:
- Go to Settings โ Sound and vibration โ Additional settings;
- Find the Dynamic Warnings (or Dynamic Protection) item and deactivate the slider.
- If there is no item, try the following method.
3. Resetting the sound settings
You can reset the sound settings to the factory without losing data:
Settings โ System and device โ Resetting settings โ Resetting sound settingsThis method helps if the failure is caused by a settings conflict after the MIUI update.

Advanced methods: disabling through ADB and system files
If standard methods don't work, you'll have to use a developer tool, which requires connecting your smartphone to your PC and having a basic knowledge of ADB.
Method 1: Disconnect via ADB (without root)
This will require:
- ๐ฅ๏ธ Computer with Platform Tools installed;
- ๐ฑ Included debugging by USB on a smartphone (Settings) โ The phone. โ Version. MIUI โ 7 times tap to activate the developer mode, then enable debugging in Settings โ Additionally. โ For developers);
- ๐ USB-cable (preferably original).
Instructions:
- Connect your smartphone to your PC and open the Command Prompt (Windows) or Terminal (macOS/Linux) in the folder with the platform-tools;
- Enter the command to check the connection: adb devices (the name of your device should appear);
- Execute the command to disable the warning: adb shell settings put global speaker_protection_enabled 0
- Reboot your smartphone.
โ ๏ธ Note: This method does not work on all versions. MIUI. If the warning comes back after the reboot, try an alternative command:
adb shell settings put system speaker_protection_disabled 1Method 2: Editing system files (requires root)
If you have root rights, you can permanently disable the function by changing the system file:
- Install a root-enabled explorer (such as Root Explorer or FX File Explorer)
- Cross the path: /system/etc/device_features/
- Find the file miui.xml and open it in the text editor.
- Add a line: <bool name="speaker_protection_support">false</bool>
- Save the file, set the rights to 644, and restart the device.
โ ๏ธ Warning: Incorrect editing of system files can lead to bootloop ( looped boot!
What if MIUI does not start after editing?
Alternative solutions: covers, settings of uniformity
If the software methods didnโt help, try to get around the problem physically:
1.Use a case with the correct neckline
Many Redmi Note cases close the bottom speaker, which causes false positives.
- ๐ The cutout under the speaker should be wider than 5 mm from the edges;
- ๐ณ๏ธ The microphone holes should not be closed;
- ๐ก๏ธ Avoid covers with ears on the sides โ they often block sensors.
2.Setting uniformity (EQ) to reduce load
Sometimes the warning comes from overloading the speakers at high frequencies.
- Open Settings โ Sound and vibration โ Uniformity
- Select the preset "Basy" or "Voice" - they reduce the load on the high-frequency speaker;
- Reduce the volume by 1-2 divisions from the maximum.
3. disabling stereo speakers (for some models)
On the Redmi Note 10 Pro and Note 11 Pro, you can turn off the second speaker via the engineering menu:
##36446337##From the menu, select Hardware Testing โ Audio โ Speaker Test and deactivate the second speaker, which will lower the sound quality, but remove the warning.
๐ก
If the engineering menu doesn't open, try the code ##4636## โ Audio โ Dynamic Type and select Mono.

What to do if nothing helps
If you've tried all of these, but the "Do not close the speaker area" warning keeps coming up, it's probably a hardware malfunction.
1. Diagnostics of the proximity sensor
Check the sensor with the test code:
##6484##In the Manual Test โ Proximity Sensor menu, cover the sensor with your hand - the value should change from 5 to 0. If there is no reaction, the sensor is defective.
2. Testing of the plume dynamics
After falls or repairs, the plume connecting the speaker to the motherboard could have been damaged.
- ๐ The sound disappears when the phone is tilted;
- ๐ต The warning appears even when the speaker is open;
- ๐ง In the service center diagnosed with โbreakdown of contactsยป.
3.Update or rollback MIUI
Some versions of MIUI (e.g., 13.0.4โ13.0.6 for the Redmi Note 11) had a massive false positive bug.
- ๐ Update. MIUI until the last stable version;
- ๐ Reverse to the previous firmware (if the bug appeared after the update).
If the warranty is still valid, contact the Xiaomi service center. SPEAKER_BLOCKED You should replace the sensor or plume free of charge.
