How to turn off the notification of the population Xiaomi: a step-by-step guide

Owners of Xiaomi, Redmi and Poco smartphones often encounter intrusive beeps, which the system classifies as “Population Alerts” or “Emergency Alerts”. This disaster warning feature, in our latitudes, is most often seen as an annoying system sound when downloading or running applications. You can remove this sound, but standard methods don't always work because of the shell. MIUI.

The problem is that Xiaomi integrates regional settings even into global firmware versions. Often, sound is not tied to the standard notification channel, but to the system level of security or even to hidden Google services. Complete shutdown is possible only by understanding what mechanism triggers the sound signal in your particular version of software. Wrong actions can lead to the fact that you stop hearing important system warnings about low charge or hardware errors.

In this article, we will discuss all known ways to fix the problem: from simple sound settings to use. ADB-We'll look at the differences between app notifications and system alerts, and we'll also learn why resetting doesn't always work, and what hidden menus you need to activate to take full control of your smartphone's audio system.

The Nature of System Notifications in MIUI

The MIUI shell is built on Android, but has a deep modification of system processes. The sound that users identify as “public alert” is often part of the Cell Broadcast mechanism or similar emergency response services. Unlike regular messenger notifications, these signals take priority and can be played even in “Do Not Disturb” mode.

It's important to distinguish between two types of sounds: One is standard app notifications that just sound loud because of the settings that are exposed; the other is system alerts that are flashed at the operator level or Xiaomi's regional settings; if the first type is solved in the audio menu, the second one requires deeper security intervention.

⚠️ By disabling the system’s emergency channels, you risk not being alerted about a real storm warning or emergency in your area if such services are maintained by the operator.

Often, false positives are caused by a conflict between the SIM card and the software. A smartphone modem can interpret the network's service signals as a command to play back sound. SIM-map of one region, and firmware is configured to another.

Basic setting of sound profiles

The first step should always be to check the standard audio settings, and many users overlook the individual sliders that handle system sounds. Go to Settings → Sound and Vibration. You need to look at all the subsections carefully, especially those labeled "System sounds" or "Notification sounds."

Some versions of MIUI have a separate menu for alarms, timers and notifications. Make sure you select a None file or a quiet sound for the default notification. If you have a standard melodic ringtone, replace it, which often solves the problem of repetitive signals that users mistake for public alerts.

Never had.

Be sure to check the settings of the particular Security app, which is the system control center in Xiaomi. It may have its own audio profiles for antivirus or cleaner, which can also sound like a system alert. Disabling the soundtrack in each module of this application can remove the intrusive signal.

Management through a special options menu

The hidden reservoir of settings is the Special Opportunities menu. This is where switches for people with hearing or vision impairments often hide, which duplicate the sound signals with vibrations or flashes, creating a sense of constant activity of the system. Go to Settings → Additional settings → Special features.

In this section, look for "Notifications" or "Audio Notifications." This can be used to voice actions or events of the system. TalkBack or other access services sometimes conflict with the media player, causing strange sound artifacts. Disabling unused accessibility services is an important step in diagnostics.

Also worth paying attention to is the "Gestural Control" section, where some actions, such as tapping on a screen or flipping a smartphone, can be tied to triggering functions accompanied by sound, and check if any actions are assigned to include a flashlight or a sound-approved camera.

☑️ Testing of special facilities

If you use third-party launchers or themes, they can take control of audio profiles. Return to the standard Xiaomi theme during diagnostics to eliminate the impact of visual modifications on the device's audio system.

Setup of Application and Channel Notifications

Modern versions of Android and MIUI allow you to manage each notification channel separately. Often, a public alert is just a loud notification from a system application, such as Google Play Services or Security. To find the culprit, wait for the sound to appear and immediately lower the notification curtain.

Click on the notification that appears and select Settings or the gear icon, and you'll be taken to the detailed control menu for that particular channel, where you can not only turn off the sound, but also disable pop-ups, look for channels with names like System Alert, Emergency or Broadcast.

SystemicSettings → Applications → All applicationsTurn off the channel sound
Security AnnexSecurity Appendix → SettingsRemove the "Sound" tick.
Google ServicesSettings → Google → NotificationsDisable critical alerts
Communications operatorMessages → Settings → SMSDisable CB (Cell Broadcast)

Pay special attention to the Messages app. This is where the Cell Broadcast settings are often hidden. Go to SMS settings, look for Cell Broadcast settings or Cell Translation, and turn off receiving Extreme, Severe, or Amber messages.

Use of Engineering Menu and ADB

For advanced users who have not been helped by standard methods, there is the option of using USB debugging and ADB commands. This allows you to disable system components that do not have an interface in the settings. You will need a computer and installed Android platform tools.

First, activate Developer Mode. To do this, go to Settings → About Phone and quickly click on MIUI build number seven times. Then, in the Developer Menu, turn on "Debugging on USB." Connect your smartphone to your PC and type a command to search for alert-related processes.

adb shell dumpsys notification | grep -i alert

This command will help identify the packets responsible for the audio signals. If you find a specific packet, you can try to disable it with the command adb shell pm disable-user --user 0 name.packet. However, be extremely careful: disabling critical system packets can lead to unstable operation of the device.

Risks of using ADB
Using ADB commands to disable system components can result in loss of warranty and a cyclic bootloop.

There is also a hidden engineering menu available through code ##6484## (CIT) that, although designed to test the hardware, can be found in some regions where modem settings affect network signal processing, and look for sections related to "Radio" or "Network."

Regional features and change of region

One of the most effective but non-obvious reasons for sound is the region of your phone settings. Xiaomi tightly ties some system features and sounds to the geographic location specified in Settings → Additional Settings → Region.

If you choose India, Russia or Europe, the system sounds and rules for playing them will differ, for example, in some regions, the default loud earthquake alert is turned on, which is tested by the network automatically. Changing the region to Singapore or the United States often removes unnecessary localized sounds.

⚠️ Note: Region change may affect some applications (e.g. Mi Video or Mi Music) by limiting access to content that is only available for a particular country.

When you change region, you have to restart the device, recalculate the configuration files, apply new audio profiles, and if the sound is gone, then the problem was with the regional firmware settings.

💡

Try to temporarily install the Andorra or Nepal region, which has the least system restrictions and intrusive service alerts from Xiaomi.

Frequently Asked Questions (FAQ)

Why does the sound appear immediately after the phone is turned on?
This is the standard behavior of the system when checking the health of the speaker or when receiving a service signal from the operator's base station at the time of registration in the network. If the sound lasts more than 2 seconds, check the autoload of applications.
Can I remove the Security System Application?
You can’t delete completely without superuser rights (Root) because it’s a system component of MIUI, but you can turn off notifications and background work through battery settings and permissions.
Does setting a third-party theme affect system sounds?
Yes, some themes contain their own audio files for system events. If the theme is not fully loaded or corrupted, it may crash.
What if the sound appeared after the software update?
Updates often reset audio profiles to factory ones. You'll need to retrace the Settings → Sound path and disable unnecessary options.

💡

Changing the region in your phone settings is the safest and most effective way to remove regional system sounds without using complex technical means.
