How to remove the message “Do not close the speaker area” on Xiaomi Redmi 7A: all ways

Xiaomi Redmi 7A owners often face an intrusive “Don’t close the speaker area” notification that appears even when the phone is flat or the speaker is not closed, which is part of the system to protect against overheating and distortion of sound, but often works falsely, preventing listening to music or talking. In this article, we will discuss why this happens, how to turn off the function permanently or temporarily, and what to do if the problem is associated with hardware malfunctions.

It's worth noting that on the Redmi 7A (as on other Xiaomi budget models), this feature is implemented software-based, without a speaker proximity sensor. The system analyzes the body temperature, volume level and even the position of the device in space. Sometimes you just put the phone down on a soft surface and the message pops up. We tested all the working methods and collected them in one guide, including hidden settings and workarounds.

Why does the notification “Do not close the speaker area” appear?

The warning is activated for three main reasons, and only one of them is related to the actual locking of the speaker.

• 🔥 Overheating of the processor: with prolonged load (games, video, charging), the temperature of the body rises, and the system mistakenly believes that the speaker is closed.
• 📢 Maximum volume. at levels above 80% Redmi 7A automatically reduces sound and displays a warning to avoid distortion.
• 📱 If the phone is on a soft surface (bed, sofa) or in your pocket, the accelerometer sensor may be triggered falsely.

Interestingly, on newer models (like the Redmi 9A or Redmi Note 10), this feature works more accurately thanks to improved algorithms, while the Redmi 7A, released in 2019, suffers from software false positives due to outdated MIUI firmware.

Another nuance: the notification may appear when you connect to Bluetooth headphones or an external speaker, this is a bug associated with the conflict of audio routes in MIUI, in which case the reset or reset of Bluetooth settings helps.

Method 1: Disconnect via the engineering menu (without root)

The most reliable method is to use an engineering menu that is hidden from ordinary users, which does not require super-user rights and works on most versions of MIUI for Redmi 7A. Importantly, not all options in this menu are safe, so only change the ones listed below.

Instructions:

1. Open the Phone app and enter the combination: ##4636##.
2. In the menu that appears, select Phone Information (or Phone Information).
3. Scroll down to the Audio block and press Speaker Test.
4. Find Speaker Protection (or Dynamic Gain Control) and turn it off by setting Disable.
5. Save the changes and restart the phone.

If there is no Speaker Protection, try an alternative path:

Settings → Additional → Special features → Sound settings → Disable “Displayer Protection”

This works on MIUI 10-12 firmware, and on newer versions (MIUI 13+), the path may be different, and the parameter itself may be hidden, so the following method will help.

Make a backup copy of the data

Check the MIUI version in the settings

Charge your phone at least 50%

Turn off Bluetooth and headphones-->

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

If the engineering menu does not help, you can turn off the speaker protection through ADB (Android Debug Bridge. This method requires a computer and minimal command line knowledge, but it's 100% effective. It's good for all versions. MIUI on the Redmi 7A.

Step-by-step:

1. Download and install ADB Tools on PC.
2. On your phone, activate Developer Mode: go to Settings → About Phone → MIUI version and tap it 7 times.
3. Return to Settings → Additional → For developers and enable USB debugging.
4. Connect your phone to your PC, open the command prompt (Windows) or terminal (macOS/Linux) and type:

adb shell settings put global speaker_protection_disabled 1

Once you've completed the command, restart the device. To return the protection, use:

adb shell settings put global speaker_protection_disabled 0

⚠️ Attention: Disable the protection speaker through ADB This method can cause overheating or damage to the speaker during prolonged playback at maximum volume. Use this method only if you are sure of the serviceability of the hardware.

💡

Before using ADB, check if the antivirus is blocking your phone connection. Add the folder with ADB to exceptions if the commands are not executed.

Method 3: Update or roll back firmware

In some cases, the “Do not close the speaker area” notification appears after the update. MIUI. This is due to bugs in new firmware versions that Xiaomi doesn’t always promptly fix. MIUI or wait for a patch.

How to check the relevance of the firmware:

To roll back on the old firmware:

1. Download the MIUI version for Redmi 7A (codename pine) from the Xiaomi Firmware Updater website.
2. Rename the file to update.zip and place it in the root folder of the phone.
3. Go to Settings → About Phone → System Update, click on the three dots in the upper right corner and select Select a firmware file.
4. Please select update.zip and wait for the process to be completed.

⚠️ Attention: Firmware rollback will reset all data on the phone. Pre-backup through Settings → Additionally. → Backup and reset.

Method 4: Hardware causes and their elimination

If the software methods didn't work, the problem could be physical damage to the speaker or sensors.

• 🔊 Pollution speaker: Dust, pile or moisture enter the grid, causing false alarms.
• 📉 Weakening of contacts. Over time, soldering of the speaker or plume may weaken, leading to errors in reading the state.
• 🌡️ Thermosensor malfunction: If the temperature sensor next to the speaker fails, the system will mistakenly "think" that the device is overheating.

How to diagnose a hardware problem:

1. Blow the speaker with compressed air (a canister for cleaning equipment). Do not use wet wipes!
2. Check if the notification appears when you play the sound at the lowest volume, and if so, the sensors are the problem.
3. Connect headphones: if the message disappears, the speaker is to blame; if it remains, the thermal sensor or plume is defective.

For repair, contact the service center. The average cost of replacing the speaker with the Redmi 7A is 800-1500 rubles, the thermal sensor is 500-1000 rubles. Self-repair is not recommended: adhesive connections are used on Xiaomi, and without experience you can damage the plumes.

Method 5: Alternative solutions (if nothing worked)

If all of the above methods have not worked, try the workarounds:

• 🎵 Use an external speaker. Connect your phone to the speaker via Bluetooth or AUX-cable - no notification will appear.
• 📱 Install custom firmware.For example, LineageOS or Pixel Experience do not have speaker protection from Xiaomi.
• 🔇 Turn off system notifications. → Annexes → Application management → System applications → MIUI System UI You can block pop-ups (but this will turn off other important notifications too).

To install custom firmware, you will need to unlock the bootloader and obtain root rights. This voids the warranty and can lead to a device blink. Detailed instructions for Redmi 7A are available on the 4PDA forum.

If you decide to go this way, consider:

⚠️ Attention: Unlocking the bootloader erases all data on the phone, including photos and apps. Xiaomi can also block the Mi Account if it detects unofficial software.

💡

Custom firmware gives you full control of the device, but it is deprived of official support. Before installing, check compatibility with the Redmi 7A (pine) model.

Prevention: How to avoid notification in the future

To prevent the warning “Do not close the speaker area” from reappearing, follow these recommendations:

• 🔥 Avoid overheating.Do not use your phone while charging for games or watching videos.
• 📢 Don't set the volume to maximum. Optimal 60-70%.
• 🧹 Clean the speaker regularly. Use a soft brush or a spray of compressed air.
• 🛏️ Don't put your phone on soft surfaces with the screen down.

It's also useful to turn off the automatic volume control in the sound settings.

1. Go to Settings → Sound and vibration → Additional settings.
2. Turn off the Adaptive Sound (or Volume Autosetting) option.
3. In the same menu, deactivate the MIUI Sound Improvement.

These settings will reduce the load on the audio system and reduce the number of false alarms.
