Don’t close the speaker area on Xiaomi Redmi 8: how to turn off the feature forever

Are you tired of the constant “Don’t close the speaker area” pop-up notification** on your Xiaomi Redmi 8?This warning appears every time you accidentally cover the bottom speaker with your hand, case, or even finger while talking. On the one hand, the feature is useful – it protects the device from overheating and distortion of sound. On the other hand, the constant pop-ups are annoying, especially if you often hold the phone in a horizontal position or use cases with high sides.

In this article, we'll look at all the ways to turn off this warning, from standard MIUI settings to hidden engineering menus, and you'll also learn why the manufacturer implemented this feature, what the risks of deactivating it are, and how to minimize the possible problems. And for those who don't want to take risks, we've prepared alternative solutions, from finding the right case to optimizing the position of the hand during calls.

Before we get into the instructions, it is important to understand that on some MIUI firmware (especially the global versions for Redmi 8), the standard settings to disable the warning may be blocked, in which case additional manipulations will be required, which we will discuss below. All methods have been tested on current versions of MIUI 12-14, but may differ depending on the regional firmware.

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

Xiaomi's shutdown protection feature was introduced for a reason, and it solves three key problems:

• 🔊 Sound distortion: A closed speaker creates a deaf sound effect, especially noticeable at low frequencies, which impairs the quality of music playback and voice calls.

The manufacturer has put the automatic detection of the speaker closure into the system using:

• 🌡️ Temperature control – if the speaker starts to heat above normal, a warning appears.

In practice, the feature often works falsely, like when you hold your phone in your hand at a certain angle or use a high-sided case, which is why many users want to turn it off.

Method 1: Disconnect via standard MIUI settings

Let’s start with the simplest method that works on most Xiaomi Redmi 8 firmware. You don’t need root rights or additional programs, just access to the phone’s settings.

Step-by-step:

1. Open the Settings app (the gear icon on the home screen).
2. Go to About Phone (usually at the bottom of the list).
3. Tap All settings (or Additional settings in some versions of MIUI).
4. Find the Dynamic Warnings tab (could be called Speaker Protection or Sound Security).
5. Turn off the slider next to the option to Warn about closing the speaker.
6. Confirm the action if the system requests permission.

If your MIUI version doesn’t have one, try an alternative way:

1. Go to Settings. → Sound and vibration.
2. Select Additional Sound Settings.
3. Find the Security Speaker section and deactivate the option.

Some firmware (e.g., the global version for Europe) may have this parameter hidden, so move on to the next way.

Method 2: Use of an engineering menu (for power users)

If standard settings don’t work, you can try turning off the warning via the Engineering Mode, a method that requires caution, as incorrect actions can disrupt the phone.

How to open the engineering menu on Redmi 8:

1. Open the Phone app.
2. Enter the combination: ##4636###.
3. Select the Engineering Menu (or Testing) item.
4. Go to the Hardware Testing → Audio section.

In the audio test menu, find parameters related to speaker protection (can be called differently, for example:

• Speaker Protection
• Dynamic Warning
• Proximity Sensor Calibration (if the problem is related to the proximity sensor)

Turn off the options and restart the phone. If you're not sure which one is responsible for the warning, don't change anything at random -- you better use other methods.

⚠️ Warning: Changes to the engineering menu may cause the audio system to malfunction. If after the protection is turned off, the speaker begins to wheez or distort the sound, return the settings to the original state or reset to factory settings.

Method 3: Disconnect via ADB (for advanced users)

If previous methods have failed, you can use Android Debug Bridge (ADB), a tool for debugging Android devices, which requires connecting the phone to a computer and basic command line knowledge.

What you need:

• 🖥️ Computer with installed Xiaomi drivers and package ADB Tools.
• 📱 Included debugging by USB on the phone (located in Settings) → The phone. → Version. MIUI, tap 7 times on the build number, then return to the Additional settings → For developers).
• 🔌 USB-cable (preferably original).

Step-by-step:

1. Connect Redmi 8 to your computer and allow debugging over USB.
2. Open the command prompt (Windows) or terminal (macOS/Linux) in the folder with ADB.
3. Enter the command to check the connection: Adb devices should appear serial number of your device.
4. Execute the command to disable the warning: adb shell settings put global speaker_protection_enabled 0
5. Reboot the phone.

If the team doesn’t work, try an alternative:

adb shell am broadcast -a android.intent.action.SPEAKER_PROTECTION_DISABLE

⚠️ Attention: Use ADB It can cause the system to run in an unstable way if you type in the wrong commands. Don't experiment with other parameters unless you're sure they're there.

Method 4: Install custom firmware (extreme case)

If none of the above methods worked, the radical solution is to install custom firmware (like LineageOS or Pixel Experience), which is only suitable for advanced users, as it requires unlocking the bootloader and potentially deprives of warranties.

The advantages of custom firmware:

• ✅ Full control over system notifications.
• ✅ Absence of unnecessary functions MIUI.
• ✅ Possibility of fine tuning of sound.

Cons and risks:

• ❌ Loss of warranty (if the bootloader is unlocked).
• ❌ Possible bugs in the work of the camera or sensors.
• ❌ Difficulty returning to standard firmware.

If you decide to do this, follow the official instructions for installing the firmware for Redmi 8 (codenamed olivelite).

• 🔄 Make a full data backup.
• 🔋 Charge your phone to 100%.
• 📥 Download the firmware from a verified source (for example, XDA Developers).

⚠️ Attention: Installation of custom firmware incorrectly can turn your phone into a brick.If you do not have experience, it is better to seek help from thematic forums or specialists.

Alternative solutions: how to avoid warning without turning off

If you don’t want to risk system stability but the warning is still annoying, try these safe alternatives:

A few more useful tips:

• 🎧 Use Bluetooth headphones – this completely solves the problem of closing the speaker.
• 📲 Activate In Your Pocket mode in the lock screen settings so that the phone doesn’t react to random touches.
• 🔄 Update. MIUI to the latest version - in new assemblies, the closing algorithm of the speaker can be improved.

💡

If the alert only appears in certain apps (such as messengers during voice messages), try turning off sound notifications for them. Go to Settings → Apps → Permissions Management → [Application Name] → Notifications and deactivate the Sound Warnings option.

Frequent Mistakes and How to Avoid Them

When trying to turn off the speaker alert, users often face typical problems, and consider the most common ones and how to solve them:

1. Can't find the settings in MIUI

The reason: on global or European firmware, Xiaomi often hides some parameters.

• Try changing the region in your phone settings to India (sometimes this opens up access to additional options).
• Install MIUI bootloader and check if there are any updates for your model.

2.After disconnecting via ADB, the alert returned

Reason: Some system settings are reset after the reboot.

• Repeat the ADB command and add it to the autoload via Tasker or MacroDroid.
• Check if the antivirus or optimizer is blocking system settings.

3.The speaker started wheezing after the defense was turned off

Reason: Without protection, the speaker can overheat or run at the highest volume.

• Return the protection settings to their original state.
• Reduce the maximum volume in the sound settings.
• Check the speaker for physical damage (dust, moisture).

⚠️ Warning: If after manipulating the settings, the phone began to restart or the speaker completely stopped working, reset to factory settings (Settings) → Additionally. → Recovery and reset. This will bring all system functions back to their original state.

💡

Turning off speaker alerts doesn't increase the phone's maximum volume! This feature is only designed to protect the device from damage. If you're not up to volume, consider using an external speaker or headphones.
