How to permanently disable the notification of the population on the phone Xiaomi: 5 proven ways

Why Xiaomi Smartphone Is Always Sending Loud Signals and How to Fix It

You suddenly heard a shrill sound from Xiaomi speakers, even though there were no notifications on the screen? It's not a glitch of the system, but the operation of the public alert function - a built-in mechanism for sending emergency messages from the Emergencies Ministry, the government or the telecom operator. In Russia, such a system is called "OCSION", in Europe - EU-Alert, and in the United States - Wireless Emergency Alerts (WEA), the problem is that these signals often fire falsely, interrupt music, wake up at night and do not have a "cance" button.

In this article, you will find current ways to disable alerts on all modern Xiaomi smartphones (Redmi, POCO, Black Shark) running MIUI 14/15 and the new HyperOS firmware. We will analyze both standard settings and hidden methods for those who do not have Emergency Alerts on the menu. Importantly, some methods require superuser rights (root), but most work without them.

Before you start, consider that disabling emergency notifications can deprive you of important information about natural disasters or man-made disasters. In some countries (for example, in the United States), the law prohibits completely turning off such signals.

Method 1: Disconnect via standard MIUI/HyperOS settings

On most Xiaomi smartphones (including Redmi Note 12, POCO X5, Xiaomi 13T), public alerts are managed via the Security menu.

1. Open the Settings app (cog icon).
2. Go to the Appendix section → Application management.
3. In the upper right corner, click on three dots and select Show All Apps.
4. In the search box, enter Emergency Alerts (or Emergency Alerts in English firmware).
5. Slip on the app you found, then select Notifications.
6. Turn off all switches: Sound, Vibration, Pop-up notifications.

If you have HyperOS (new firmware for Xiaomi 14, Redmi K70, etc.), the path may be different:

• 🔍 Settings → Memory and applications → All applications → Emergency alerts
• 🔔 Turn off Allow notifications and sound signals
• 📱 On some models you need to go further → Sound and vibration → Emergency signals

Important: On smartphones with Global ROM (European/Indian firmware), the Emergency Alert may not be available. In this case, move to Method 3.

Method 2: Blocking through settings SIM-Cards (for Russian operators)

Russian operators (MTS, Beeline, MegaFon, Tele2) send emergency alerts via Cell Broadcast (CB) channel, which can be blocked directly:

1. Open the Phone app and type the combination: ##4636## (some models may not work, then use an alternative method).
2. In the menu that appears, select Phone Information (or Phone Information).
3. Scroll down to the Cell Broadcast block and turn it off.

If the combination doesn’t work, try an alternative path:

• 📱 Settings → SIM-maps and mobile networks → Settings SIM-Cards (your operator) → Additional settings → Cell Broadcast Channel
• 🔕 Turn off the switch to receive messages CB or emergency alerts

Check the balance. SIM-cards (some operators block settings when the balance is negative)

Make sure your smartphone is connected to the network (not in “airplane” mode)

⚠️ Warning: Disabling Cell Broadcast may affect the reception of some service SMS If important messages are missing after the changes, return the settings back.

Method 3: Use ADB-Teams (for experienced users)

If standard methods don’t work, you can block alerts via Android Debug Bridge (ADB), which requires a computer and developer mode to be enabled, but doesn’t need root rights.

Instructions:

1. Turn on Developer Mode: Settings → About Phone → MIUI version (tap 7 times in a row).
2. Return to Settings → Additional → For developers and activate Debugging over USB.
3. Connect your phone to your PC, install it. ADB-Drivers and open the command line in the folder with the platform-tools.
4. Enter the commands in turn: adb shell pm disable-user --user 0 com.android.cellbroadcastreceiver pm disable-user --user 0 com.android.emergency (for HyperOS, an additional command may be required: pm uninstall-k --user 0 com.miui.yellowpage).

To return the alerts, use:

pm enable com.android.cellbroadcastreceiver


pm enable com.android.emergency

⚠️ Note: Some Xiaomi firmwares disconnect through ADB It's resetting after the system updates.

Method 4: Remove system applications (requires root)

If you have root rights (like Magisk), you can completely remove the apps that are responsible for alerts. This is a radical method, but it works.

List of removal annexes:

Use any root-enabled file manager (such as Root Explorer or FX File Manager) to delete:

1. Go to /system/priv-app/ or /system/app/.
2. Find the folders with the names from the table above and delete them (or rename them by adding.bak at the end).
3. Reboot the phone.

💡

Before you delete your system files, back up your phone via TWRP or another custom recavator, which will help you recover your phone in case of a "brick" (unboot state).

Method 5: Alternative methods (without root and ADB)

If previous methods didn’t work or seemed too complicated, try these workarounds:

• 📵 In the plane mode at night: Set up automatic flight mode for sleep through Settings → Battery and productivity → Flight schedule, it blocks all notifications, including emergency alerts.
• 🔇 Turning off the sound for a specific application: Press the notification of the alert → Select Turn off the sound or notification settings → Set priority Low.
• 🛡️ Blocking through third-party apps: Install Notification Blocker or AutoNotification from Google Play.These programs can filter notifications by keywords (e.g., “EMERCOM” or “OCSION»).
• 📲 Firmware change: Switching to custom firmware (like LineageOS or Pixel Experience) completely removes Xiaomi's built-in alerts. MIUI/HyperOS.

💡

The most reliable way without root is to turn off Cell Broadcast in the settings SIM-map + blocking notifications through ADB. It works on 90% of Xiaomi models.

What do you do if nothing helps?

If you’ve tried all the methods but the alerts keep coming, the problem may be:

• 📡 Firmware updates: After the update MIUI/HyperOS Some settings are reset. Check them again.
• 📶 Double. SIM-Map: Alerts may come in second SIM. Turn off Cell Broadcast for both cards.
• 🔄 Regional settings: On smartphones with Chinese firmware (China) ROM) Emergency notifications are managed differently. Try changing region to Settings → Additionally. → Region on "Russia" or "Europe».

If you live in a region where alerts come in too often (such as in frequent emergency areas), consider buying a smartphone without Cell Broadcast support. Among Xiaomi, these are models for the Chinese market (China ROM) or devices without Google certification (such as Black Shark in some versions).

Last tip: if alerts come from a specific operator, call support and ask them to turn off the newsletter service, which they are legally obliged to provide (although they may refuse to do so with a reference to “required notifications”).
