How to permanently disable public alerts on Xiaomi: 5 proven ways

Emergency alerts are a useful feature, but not always appropriate. Smartphone owners Xiaomi, Redmi and POCO regularly face sudden signals of the Ministry of Emergency Situations, or emergency warnings, which are issued at full volume even in silent mode. These notifications are impossible to miss: they block the screen, make a piercing sound and often come at the most inopportune time – during an important call, at night or at a meeting.

Compounding the problem, the manufacturer hides the shutdown settings in deep MIUI menus, and after system updates, the settings can migrate or disappear. In this article, we will discuss all the current ways to deactivate such alerts, from standard settings to hidden commands for power users. Instructions are tested on MIUI 14/15 and Android 13/14, but most methods can be used on older versions.

Why public alerts cannot be turned off in the standard way

The point is that in Russia (as in several other countries), telecom operators and device manufacturers are required to ensure the delivery of emergency notifications from public services.

• 📜 Federal law № 248-FZ (on the security of critical information infrastructure)
• 📡 Order of the EMERCOM of Russia № 476 (on the procedure for notifying the population)
• 📱 EAEU Technical Regulations for Mobile Devices

So Xiaomi can't give the user a "one button" to completely shut down, which would violate local regulations. However, workarounds do exist. The main rule is that the methods differ depending on the version of MIUI and the firmware region. For example, on global (Global) and European (EEA) firmware, settings may not be available at all, whereas in Chinese (China) or Russian (Russia) versions they are available.

Another nuance: some alerts do not come through system channels, but through SMS-mailing (called Cell Broadcast), which requires separate actions to block.

Method 1: Disconnect via “Security Settings” (official method)

This is the easiest and most secure way to do this, and it works on most devices with MIUI 12 and later, and is suitable for disabling the warnings of the Emergencies Ministry, the RKN and other government services:

1. Open the Settings app (cog icon).
2. Go to Passwords and Security (or Privacy on some firmware).
3. Select Emergency Alerts (could be called Emergency Alerts or Security Alerts).
4. Turn off the sliders next to: 🚨 Hazardous weather conditions ⚠️ Emergency situations 📢 Governmental alerts

If the Emergency Alerts section is not on the menu, your firmware does not support this method, then go to Method 2.

⚠️ Note: On some devices (e.g. Redmi Note 10 Pro with a MIUI 13) after disabling the alerts through this menu, they may be activated again after restarting (ADB-team).

Method 2: Cell Broadcast lockdown (SMS-warning)

Cell Broadcast is a mass-mailing technology for all devices in the network coverage area, and it's through it that the Emergencies Ministry alerts often come with a characteristic audible signal, and you can turn them off like this:

1. Open the Messages app (the envelope icon).
2. Click on the three dots in the top right corner and select Settings.
3. Go to Additional Settings → Emergency Alerts.
4. Turn off all available channels (usually Disaster Warnings and Government Alerts).

If there is no emergency alert, try an alternative route:

1. Enter the dialer code: ##4636##.
2. Select Phone Information → Battery settings (don’t be afraid, this is an engineering menu).
3. Scroll down to the Cell Broadcast block and turn off all options.

Important: After disabling Cell Broadcast, you will not receive not only emergency alerts, but any other mass alerts. SMS-mailings from the operator (for example, about technical work).

Method 3: Using Blocking Applications

If the system methods didn't work, you can use third-party utilities.

• 🛡️ «Do Not Disturb: Create a rule to block notifications from the system. → Sound and vibration → Don't disturb. → Automation rules. Add a rule with trigger Emergency alerts and action Block.
• 🔇 AppOps (requires root): allows you to disable permissions for system applications. Find com.android.cellbroadcastreceiver and block the option SHOW_TOAST.
• 📵 Automation Apps (Tasker/MacroDroid): Create a macro that automatically closes pop-ups with the word "Population Alert." Example of a condition for MacroDroid: Trigger: "Notification received" → Annex: "System settings" Action: "Close the notification" → ID: "android.alerts"

⚠️ Note: Apps like AppOps require a super-user (root) right, and their use can compromise the warranty and stability of the device. MIUI With a blocked bootloader, such utilities will not work.

💡

If you use Tasker, add the “Set Volume to 0” action to your macro when you detect a notification from com.android.cellbroadcastreceiver. This will drown out the alert sound even if the window does pop up.

Method 4: Disconnect via ADB (for power users)

If previous methods didn't work, the most reliable way is to use ADB (Android Debug Bridge), which works on any firmware, including global firmware, where the settings are hidden.

• 🖥️ Computer with installed Xiaomi and ADB-tools drivers.
• 📱 Included Debugging by USB on the phone (path: Settings) → The phone. → Version. MIUI → 7 times press to unlock the developer mode, then Settings → Additionally. → For developers → Debugging by USB).

Instructions:

1. Connect your phone to your PC and open the command prompt (cmd) in the folder with adb.exe.
2. Enter the command to check the connection: Adb devices must appear serial number of your device.
3. Follow the commands in turn: adb shell pm disable-user --user 0 com.android.cellbroadcastreceiver adb shell settings put global captive_portal_detection_enabled 0
4. Reboot the phone.

To return the settings to the original state, use:

adb shell pm enable com.android.cellbroadcastreceiver

Method 5: Reset network settings (last resort)

If alerts keep coming and other methods don’t work, try resetting your network settings, which will delete all stored Wi-Fi networks, passwords and mobile internet settings, but often solves the problem with Cell Broadcast’s stuck channels:

1. Go to Settings. → SIM-maps and mobile networks.
2. Select Network Settings Reset (or Wi-Fi, Mobile Network, and Bluetooth Reset).
3. Confirm the action and restart the phone.

After discharge:

• 🔄 Set up your mobile network connection again (you may need to enter) APN).
• 📶 Check if the alerts have returned (sometimes you need to repeat Method 2).

⚠️ Note: On some devices (Xiaomi) 12T, Redmi K50) After the network is reset, the alerts can return in 24 to 48 hours, and this is due to the automatic update of the operator's configuration. ADB-team.

💡

Network resets are not a panacea, but they do help in 60 percent of cases where alerts get stuck in system channels, and always try them in tandem with other methods for lasting results.

What to do if nothing helps

If you’ve tried all the ways but the alerts keep coming, there are still radical measures:

• 🔧 Installing custom firmware (like LineageOS or Pixel Experience) will completely remove Xiaomi's system applications that handle alerts. MIUI (For example, design or brand gestures).
• 📦 Replacement of firmware with Chinese version (China) ROM). There are no mandatory state alerts in China, so the corresponding modules are disabled by default in this firmware.Risk: there may be problems with Google services and localization.
• 🛡️ Using a second phone.Some users buy a budget phone (e.g. Redmi). A2) specifically SIM-cards, leaving the main phone without a mobile network (wi-fi only).

Before using these methods, assess the risks:

If you decide to re-flash, be sure to:

1. Make a backup of the data through Settings → Additional → Backup and Reset.
2. Unlock the bootloader officially through the Xiaomi website (can take up to 7 days).
3. Use the verified firmware from the XDA-Developers forum.
