How to remove the public alert on Xiaomi: the full guide 2026

System alerts for emergencies, weather conditions or government notifications on Xiaomi smartphones can be a real problem, especially when they appear at the most inopportune moment – during an important call, a game or at night. Unlike normal push notifications, these messages come at the operating system level and often ignore the “Do Not Disturb” modes.

In this article, we will analyze all the current ways to disable public notifications on Xiaomi, Redmi devices, POCO and Black Shark is managed MIUI 12-14 (including global and Chinese firmware versions) It is important to understand that some methods require superuser rights or may affect the stability of the device. We will also explain which notifications can be blocked legally and which can only be blocked through workarounds.

1.What is a “public alert” and why it is difficult to turn it off

Emergency Alerts are system notifications sent by telecom operators or government agencies in case of emergency, and are divided into several types:

• 🚨 Presidential Alerts are the highest priority, they cannot be turned off without root rights.
• 🌪️ Extreme Weather Alerts – hurricanes, floods, storm warnings.
• 🚔 Emergency situations (AMBER Alerts – Search for missing children, terrorist threats.
• 📢 Test notifications – check the system operation (you can turn off in the settings).

On Xiaomi smartphones, these notifications are implemented through Cell Broadcast, which operates at the modem firmware level, which is why standard blocking methods (for example, disabling notifications for the Messages app) do not work, and in some countries (for example, in the United States or India), disabling critical alerts may be prohibited by law.

⚠️ Note: On devices with firmware for the Chinese market (China) ROM) Some of the alerts come through Mi Cloud and Xiaomi Security, and their disabling can lead to disruption of other functions, such as device search.

2. Legal ways of disconnection (without root rights)

If you're tired of getting test notifications or notifications about minor weather changes, try standard methods first. They don't require superuser rights and are safe for the device.

2.1. Disconnection through notification settings

The easiest way is to limit the types of alerts in the settings menu:

1. Open the Settings app.
2. Go to the Appendix section → Application management.
3. Find the Messages app (or Messages) and select Notifications.
4. Scroll down to the Emergency Alerts (or Emergency Alerts) block.
5. Turn off unnecessary types of notifications other than presidential ones (these may not be blocked).

On some firmware MIUI This section can be called Security and Emergency Alerts or hidden in Additional Settings. If it's not, then your firmware version doesn't support manual control.

Use of the “Do Not Disturb” mode

Although public warnings ignore the standard regime DND, into MIUI 13/14 Deep sleep has been introduced, which can partially block system notifications:

• 📱 Go to Settings. → Sound and vibration → Don't disturb.
• 🔄 Turn on the mode and select Deep Sleep.
• ⏰ Set a schedule (for example, from 23:00 to 7:00).
• ⚙️ In additional settings, enable the option to Block system notifications.

This method does not guarantee 100% blocking, but it will reduce the number of nightly alerts. Note that in deep sleep, alarms and reminders are also turned off!

2.3. Disconnection through SIM-Card (for some operators)

Some mobile operators (for example, MegaFon or Beeline in Russia) allow you to turn off the distribution of alerts through your personal account.

1. Go to your operator's website.
2. Go to the Services section → Management of notifications.
3. Find the Emergency Alert or Cell Broadcast option.
4. Turn off unnecessary types of mailings.

Note that this method does not work with all operators. Tele2 They do not provide such opportunities for natural persons.

3. Advanced methods (with root rights or ADB)

If the legal ways don't work, you'll have to use more radical methods, which require unlocking the bootloader, getting root rights, or working with the software. ADB. These actions may result in loss of warranty or unstable operation of the device.

⚠️ Note: On bootloader devices, trying to get a root right will lead to a hard brick. Before you start, check the bootloader status with the command: fastboot oem device-info If Device unlocked: False, first unlock it through the Mi Unlock Tool.

3.1. Disconnection through ADB (rusty)

With Android Debug Bridge, you can turn off some of the system alerts.

1. Enable USB debugging in the developer settings (Settings → About Phone → MIUI version – tap 7 times, then go back to Additional settings → For Developers).
2. Connect your phone to your PC and execute the commands: adb shell settings put global cell_broadcast_alerts 0
3. To disable specific types of alerts, use: settings put global cell_broadcast_test_alerts 0 # Test settings put global cell_broadcast_amber_alerts 0 # AMBER

These commands temporarily disable notifications until the next reboot, and you'll need to create a script in init.d or use Tasker to have a permanent effect.

Removal of system applications (root required)

On rooted devices, you can remove or freeze applications that are responsible for alerts:

• 🔧 Use Root Explorer or Titanium Backup to remove: com.android.cellbroadcastreceiver is the main alert module. com.miui.yellowpage is Xiaomi’s local notification service (China only). ROM).
• 🧊 Freeze via Lucky Patcher or App Quarantine.

Removing these applications may disrupt your mobile network or emergency call services (112, 911). TWRP!

3.3. editing of the build.prop file

For experienced users, there is a way to disable alerts through the build.prop system file:

1. Open build.prop in the root directory (/system/build.prop) with Root Explorer.
2. Add the lines: ro.cell_broadcast.enable=false persist.radio.cell_broadcast=0
3. Save the file, set the rights to 644, and restart the device.

This method doesn't work on all firmware. If your phone loses network after you restart, delete the lines you add.

4. Alternative solutions: firmware and modified ROM

If none of these methods work, the radical option is to flash the device, which is a last resort, but it gives you complete control over the system notifications.

Install custom firmware (for example, LineageOS)

Firmware on the base AOSP (LineageOS, Pixel Experience, for example, do not contain proprietary Xiaomi services, including the alert module:

• 🔓 Unlock the bootloader (possible loss of warranty).
• 📥 Install TWRP ornamental.
• 🖥️ Find compatible firmware for your model (e.g. Redmi Note 10 Pro – sweet).
• ⚠️ Make a full backup of the current system.

After installing LineageOS, alerts to the public will come through the standard Android module, which can be disabled in the settings.

Modified MIUI-firmware

There are unofficial assemblies MIUI with remote system applications, for example:

• 🌍 MIUI EU (European version – without Chinese services.
• 🛡️ MIUI pro MIUI Mix – Optimized builds with advanced settings.

These firmware often contain patches to disable alerts through the Settings menu. → Additionally. → Alert management, however, also requires an unlocked bootloader to install.

Not all methods work on all firmware. The table below shows the compatibility of the methods with versions. MIUI and device models:

For devices on HyperOS (new firmware Xiaomi, which replaced the new version) MIUI in 2026) some methods may not work. ADB custom-made.

6. Frequent mistakes and how to avoid them

When trying to turn off alerts, users often encounter problems, and here are the most common errors and solutions:

• 🔒 "I can't get root rights on new devices (Xiaomi) 13/14, Redmi Note 12) Requires to unlock the bootloader through the official Mi Unlock Tool (binding to the Xiaomi account is mandatory).
• ⚠️ "An "uncertified device" warning appears, a consequence of unlocking the bootloader. To remove the message, hide the unlock status through Magisk (Universal SafetyNet Fix module).

If after manipulation the device stopped turning on (hangs on the logo) MI), Try to go to fastboot and execute the command:

fastboot flash boot magisk_patched.img
