How to Remove 'Don't Close the Speaker Area' on Xiaomi: The Complete Guide

Owners of Xiaomi, Redmi and POCO smartphones often encounter an intrusive system notification that reads, "Don't close the speaker area." This message appears at the top of the screen whenever you palm the top of the display where the speaker is located. The system interprets this action as an attempt to bring the phone to the ear during a call, activating the proximity sensor and blocking the screen. In normal conditions, this is a useful feature, but in everyday use it can be annoying.

This window's constant pop-up interferes with watching videos, reading books, or navigating the interface, especially if you hold the device in a certain way. The problem can be caused by software failure in the MIUI or HyperOS shell, as well as physical contamination of the sensor. In this article, we'll look at all the effective ways to fix this bug, from simple settings to deep cleaning the system.

Before we start to do complex manipulations, it's important to understand the nature of this warning. A smartphone uses an infrared sensor located next to a front camera or speaker to determine the distance to an object. If the system receives a signal that an object is closer than a few centimeters, it forces the display to turn off to save energy and prevent accidental cheekstrokes, and our goal is to teach the device to ignore false signals or remove the notification itself.

Reasons for System Notification

Understanding the root of the problem helps you choose the right solution, and most often, the notification "Do not close the speaker area" is caused by incorrect calibration of the proximity sensor. After a drop, changing the screen or even simply updating the firmware, the program values of the sensor can get lost, in which case the phone begins to respond to the slightest change in the lighting in the speaker zone.

Another common cause is physical pollution: the top of the case, where the speaker is located, eventually accumulates dust, skin fat and pile from pockets. Even the thinnest film of dirt can block the infrared radiation of the sensor, making the system think that the phone is pressed to the ear, and can cause thick protective glasses or improperly pasted films that block the interference of the active area.

Sometimes the problem is a conflict of software modules: Third-party applications that have access to call or screen management may not properly process sensor data. In rare cases, it may be a bug of a particular version of Android that requires waiting for a patch from developers or manually adjusting system files.

Basic settings and checking protective accessories

The easiest and often overlooked step is to check physical accessories. If you use a security glass, make sure it has a special cutout or a transparent zone above the speaker. Some black-framed "glasses" can enter the sensor area, creating a permanent shadow that the system perceives as an object approach.

Try to temporarily remove the cover and wipe the top of the screen with a microfiber with a little alcohol solution. Make sure that the speaker is not visible in the grid. If after cleaning the problem disappeared, then it was the hygiene of the device. If the notification continues to appear even on a clean screen without a case, we go to software methods.

In some Xiaomi models, there is the option to disable In-Pack mode, which is closely related to the operation of the proximity sensor, which is designed to lock the screen when the phone is in the bag, but often causes false positives.

• 📱 Open the Safety app (green icon with lightning).
• ⚙️ Click on the gear icon in the upper right corner to enter the settings.
• 🚫 Find the option “Mode in your pocket” and turn off the switch.
• 🔄 Restart the device and check the result.

Disabling this mode does not affect communication quality, but can remove false screen locks. However, if the sensor is physically contaminated, software disabling the mode in your pocket may not help completely, since the system speaker notification is a separate module.

Calibration of the proximity sensor through the engineering menu

The most effective way to solve this problem is to recalibrate the sensor, and the MIUI and HyperOS shells have a special engineering menu that allows you to reset the sensor settings to factory values, which helps in 90% of cases, if the screen and sensor are physically healthy.

To enter the diagnostic menu, use a special code in the Phone app. Open the "call" and dial the combination ##6484##. If the code does not work, try ##4636## or go to the settings via the About Phone menu (repeatedly click on the kernel version).

In the CIT menu that opens, you need to find a point associated with the proximity sensor, which can be called the Proximity Sensor, the Approach Sensor, or have an icon that looks like a wave phone. Choose this item.

On the calibration screen, you'll see two values: distance in centimeters and status (Near/Far). Cover the top of the screen with your palm, the value should change and the green indicator will turn on. Remove your hand, the value should return to the original value (usually 5.0 cm or Far status). If the values do not change, the sensor may be defective.

To perform the reset, press the Calibrate button at the bottom of the screen. Once successful, you will see "Pass" or "Calibration Success." Be sure to restart your phone after the procedure.

⚠️ Warning: Do not force the Pass button if the test has not been passed. First make sure the sensor is responding to your hand, and only then start the calibration. Forced passing the test without a real sensor response can exacerbate the problem.

Resetting sound and multimedia settings

Sometimes the error is not in the sensor itself, but in the module that processes audio streams and switching between the speaker and the speaker, and resetting the audio settings can restart the relevant services and eliminate the software glitch.

To do this, go to Settings → Sound and Vibration. Scroll down and find the option to reset the audio settings (not available on all versions of MIUI). If this option is not available, you can try a more radical but safe method - clearing the data of the system application "Settings".

Go to Settings → Applications → All apps. Find Settings (cog icon) in the list. Click Clear → Clear Everything. This action will reset all your personalized system settings (alarm clocks, wallpaper, Wi-Fi password settings will have to be re-entered), but often eliminates deep system interface errors.

Using ADB to disable notification

For advanced users who don’t want to put up with an intrusive message and are willing to use a computer, there is a method of disabling the notification via USB debugging.This method does not fix the sensor, but removes the visual reminder that interferes with the user.

You'll need a PC, USB-cable and installed drivers ADB. On the phone, turn on “Developer Mode” (7 times click on the build number in “About Phone”) and activate “Debugging by phone” USB». Connect your smartphone to your computer.

In the command line on the PC, enter the following command to check the connection:

adb devices

If the device is displayed, try disabling the specific system component that monitors proximity in the interface. The command may vary depending on the version of MIUI, but often disabling the system component miui-proximity or similar helps:

adb shell pm disable-user --user 0 com.miui.proximity

Important: Be careful when using ADB. Disabling critical system processes can cause your phone to run unstable. If you are unsure of your actions, you should skip this step.

⚠️ Attention: Use of teams ADB You can cancel the warranty if the software is damaged, and you do everything at your own risk.

Hardware problems and replacement of parts

If neither software calibration, resetting, or cleaning work, there's a high probability of hardware failure. The proximity sensor is a physical component that can fail, and this often happens after the phone drops down or moisture hits.

In some Xiaomi models, the proximity sensor is combined with a front camera or built into the screen plume. If you recently changed the display or glass, perhaps the wizard used a poor-quality spare part without a working sensor or poorly connected the plume.

• 🔍 Check if the screen's autobrightness is working (it often uses the same light sensor).
• 🔊 Listen to whether the sound switches when you ring when you hold the phone to your ear (even if the screen does not go out).
• 🛠️ Consider the area of the speaker under the magnifying glass for cracks or oxides.

In the case of hardware failure, the only solution is to replace the part, and in modern smartphones, the entire screen module is often changed because the sensor is soldered into it, and the cost of repair depends on the model of the device.

💡

Before going to the service center, take a screenshot of the calibration result from the engineering menu, which will help the wizard quickly understand that the software reset has already been carried out, and the problem is precisely in the hardware.

Prevention and useful recommendations

To prevent the problem of "Do not close the speaker area" from returning, you should follow simple rules of operation: regularly wipe the top of the screen, especially after talking when the phone is in contact with the skin of the face. Use high-quality protective glass with the right cutouts.

Avoid installing cleaners or accelerators from unreliable sources, which may conflict with system processes for managing sensors, and only update the system through official notifications to avoid firmware bugs.

If you notice that the problem started after you upgraded to a specific version of MIUI, look for information on the forums. This may be a known bug, and the next patch will fix it, in which case you can temporarily roll back to the previous version of the software.

💡

Timely calibration of the proximity sensor through the engineering menu solves the problem in most cases, if the screen has no physical damage.
