You're waiting for an important message, but Xiaomi's screen is silent - no sound, no pop-up banner, not even an icon in the status bar, POCO Mi is more common than it seems: according to statistics of service centers, one in five owners MIUI It's a problem that we've encountered at least once, and it's caused by both software failures in the shell and hardware constraints in budget models.

In this article, we’ll look at 10 key reasons why notifications stop popping up on screen, from simple setting errors to hidden firmware bugs. You’ll learn how to check for permissions for apps, reset cache MIUI, Bypass power saving restrictions and even diagnose a display malfunction. A1) give individual solutions - their firmware often conflicts with modern messengers.

Warn immediately: if the problem occurred after the update MIUI 14/15, Don't rush your phone to the factory settings. 80% In some cases, a rollback to the previous version of the firmware through Fastboot helps - but only if you saved a backup copy to the Mi Cloud.

1. Notification settings in MIUI: what you might have missed.

The first thing to check is the global notification settings in the shell. MIUI. Even if you didn't change anything, updating the system or resetting the cache could reset the default settings. MIUI 12.5+, Xiaomi has tightened its energy saving policy.

Open the Settings. → Notifications and status bar → Notification management. Here, it's important to look at three things:

• 🔔 Pop-up notifications: if the slider is turned off, banners will not appear on the screen (only the icon in the panel).
• 📱 Icons on the lock screen: the disabled option hides notifications when the display is blocked.
• 🔕 Quiet mode: in MIUI 14/15 It can block vibrations and sounds, but leave icons (check Settings). → Sound and vibration).

Also in MIUI There's a hidden "Do Not Disturb Schedule" feature that automatically turns off notifications at specified hours. → Sound and vibration → Don't disturb. → If there's a random time frame (like 22:00 to 7:00), reset them.

Energy Conservation Limits: Why MIUI block out background work

Energy conservation in MIUI — The main reason notifications don't arrive on time or disappear altogether: Xiaomi aggressively optimizes the background of apps, especially on budget models (Redmi) 9A, POCO M3). Even if you have not configured anything, the system can automatically add the messenger to the list of "Limited Applications".

To check it out:

1. Go to Settings → Battery and Performance → Battery Consumption Management.
2. Select an app that doesn’t send notifications (like WhatsApp or Telegram).
3. Make sure you choose “No Limits” (not “Energy Saving” or “Intelligent Control”).

For MIUI 13/14 Add the application to "Secure Applications" (path: Settings) → Battery. → Battery settings → Secure applications. This will prevent the system from forcing the process to close, and if you don't have an option, try an alternative way:

Settings → Special features → Improved performance → Secure applications

💡

On some firmware POCO The energy saving option is hidden. To find it, search for the settings for "battery consumption".

Application malfunctions: cache, data and permissions

If notifications don’t come from just one app (like Viber or Instagram), the problem lies in its settings or data, starting with checking permissions:

• 📲 Open the Settings. → Annexes → Application management.
• 🔍 Select a problem application → "Permits".
• 🛠️ Make sure it's on: 📩 "Notifications” (principal authorization). 🔊 "Sound and vibration” (for escort). 🔄 "Auto-start" (critical for background work).

If permissions are in order, but notifications still do not come, clear the cache and application data:

1. In the same application management menu, click "Storage".
2. Select "Clear Cache" (it's safe).
3. If it does not help, click "Clear the data" (you will have to re-enter the account).

For instant messengers (Telegram, WhatsApp) after cleaning the data, check if notifications are enabled inside the application itself. For example, in Telegram, go to Settings. → Notifications and sounds and make sure you don’t check “Disable Notifications” for a specific chat.

System failures MIUI: cache, firmware and factory settings

If notifications are lost in all applications, the system itself is to blame. MIUI There are three critical points of failure:

1. A damaged system cache (often after an update)
2. Firmware conflict (for example, after manual update via Fastboot).
3. Reset settings (if previously performed Wipe Data without backup).

Let’s start with the most innocuous – cleaning the cache:

1. Turn off the phone.
2. Press the Power button + Volume up to enter Recovery.
3. Select Wipe & Reset → Wipe Cache (not to be confused with Wipe Data!).
4. Reset the device.

If that doesn't work, check the firmware version. MIUI 14.0.3-14.0.6 There was a bug that didn't show notifications on the lock screen, so the solution was to upgrade to the latest stable version or roll back to the lock screen. MIUI 13 (If the problem has occurred after the upgrade:

• 📥 Download the firmware from the official Xiaomi website (choose Stable, not Developer).
• 📁 Place the file in the root of the phone’s memory (folder) downloaded_rom).
• 🔄 Go to Settings. → The phone. → Updating the system → Three points. → Select a firmware file.

The last thing you can do is reset to factory settings, but before you do that, you have to:

• 🔄 Make a backup copy through Settings → The phone. → Backup.
• 📝 Write down logins / passwords from accounts (after reset, you will need to re-authorize).
• 📱 Make sure you know the Mi Account data – without it, your phone could be locked!

💡

If notifications are not only displayed on the lock screen, but there is in the curtain - the problem is in the Always On Display settings (AOD) display-driver.

6. Conflicts with third-party applications and launchers

Many Xiaomi users install third-party launchers (Nova, Apex), optimizers (Greenify, AccuBattery), or ad-blocking apps (AdGuard, Blokada). MIUI, block.

How to diagnose:

• 🛡️ Temporarily shut down. VPN/Ad blockers (they can filter push notifications).
• 📱 Return to Standard Launcher: Settings → Home. → Launcher MIUI.
• 🔍 Check the list of "Special Permits": Settings → Annexes → Application management → Three points. → Special access → Battery Optimization Make sure messengers aren’t optimized.

Memory cleanup applications (such as Clean Master) are particularly insidious, and they force the background processes to close, so that notifications don't come in. Delete them and use the built-in tools. MIUI:

1. Settings → Battery. → Memory Cleanup (Switch Off Automatic Cleanup).
2. Settings → Annexes → Cleaning (set manual mode).

💡

If you are using Second Space (Second Desktop) MIUI), notifications may be duplicated or missing. Check the sync settings in Settings → Second Space → Notifications.

7. Features of specific Xiaomi models

Some Xiaomi models have unique notification bugs, and here are the most common ones:

1. Turn it off. AOD In Settings → Screen. → Always On Display.
2. Reboot the phone.
3. Turn it on. AOD Re-check the notifications and check the notifications.

If you have a Redmi Note 7/8 or an older model, the problem may be in an older version MIUI. These devices are not officially supported MIUI 14, And users often install custom firmware (e.g. Pixel Experience:

• 📥 Install the official global firmware through Fastboot.
• 🔧 Use Magisk for manual patching of system files (power users only!).

8 Additional diagnostic methods

If none of the above helps, use the hidden tools. MIUI diagnostic:

Verification of notification logs:

Settings → About Phone → MIUI version (shap 5 times to turn on Developer Mode)


Next: Settings → Additional → Developer settings → Notification log

2.The test through ADB (for advanced users):

adb shell dumpsys notification
