When long-awaited messages from messengers or emails do not appear on a blocked Xiaomi, it is one of the most common complaints of users: it is not just a minor inconvenience, but a serious communication violation that can lead to the skipping of important calls or work tasks. Often the problem lies in the aggressive energy saving policy of the MIUI system, which seeks to extend battery life by closing background processes.
Smartphone owners often find their settings go wrong after updating their firmware or installing a new app. Android, which runs the shell, also has its own notification management mechanisms that can conflict with system limitations. Understanding how these layers interact is key to quickly resolving the problem.
In this article, we will go through all the possible reasons for the lack of alerts, we will go from simple menu switches to complex customizations of special features. A critical point is the setting of “AutoStart”, without which many applications can not work in the background on Xiaomi.
System settings of notifications in MIUIThe first step should always be to check the basic parameters of the operating system. Sometimes users accidentally turn off the display of content on a locked screen for the sake of privacy or simply out of negligence. → Notifications and status bar → Lock screen. This is the Format master switch that controls the visibility of the data, and if you select Do Not Show, you will only see the application icon, not the text of the message. Change the setting to Show All Notifications or Show Notifications but Hide Their Content, depending on your preferences. Make sure that the green light is on when new messages arrive if your device is equipped with an LED, or the screen light is turned on.
Even if system settings allow for the output of information, the application itself may be limited. MIUI Each application has its own notification profile, which you need to set up separately. → Notifications and status bar → Manage notifications and find a problem app like Telegram or Viber. Inside the app menu, make sure the Allow Notifications slider is activated. Below you will see a list of notification types (messages, calls, ads). Click on the Message type and check to check the "On lock screen" box. Without this checkbox, the system will ignore the application requests when the display is off. 💡Use search in settings: enter the application name in the settings search bar and select Notifications to get to the desired menu faster.
Energy saving and background problems Aggressive energy saving is the main reason Xiaomi stops showing notifications. The system can “kill” the application process as soon as you fold it or lock the phone. To prevent this, you need to set up autorun. Go to the application Security → Permissions → Autorun and turn on the switches for all important messengers. In addition to autorun, you need to fix the application in memory. Open the list of running applications (bottom up swipe and hold or menu button), find the application window you need to start, and this will clear the system from the lock. ☑️ Power Saving Setting Enable Autostart in Security App Secure App In Memory (lock) Select No Restrictions mode in Battery Disable Traffic Savings for Application Completed: 0 / 4 ⚠️ Warning: Setting “No Limits” mode for dozens of apps can significantly reduce your smartphone’s battery life.
Often users forget that they have activated Do Not Disturb or Alarm mode, which blocks all visual and audible signals. Check the notification curtain and make sure the crescent icon is not burning. Also in the Sound and Vibration settings → Don't disturb can be set time slots when the phone goes into silent mode automatically. There's also the "Important" mode, which filters notifications by only missing selected contacts. If it's on, messages from other people just won't reach the lock screen. Check the list of favorites in the Contacts app and priority settings in the notifications section. 📊 How often do you miss notifications?Daily Once a week Only after the update Never had a problem
Special features and third-party launchers The use of third-party shells (launchers) can cause conflicts with the system interface of the lock MIUI. If you have installed a Nova Launcher, Lawnchair or other interface, try temporarily disabling it and returning to the standard. System themes can also affect the display: some modified themes do not properly handle the scripts output notifications. → Special features check if services that can intercept screen control are enabled, and sometimes services for people with disabilities block the standard dialogs of the system. It is worth noting that some “memory cleaners” from third-party developers can work more aggressively than the system itself. MIUI, force-closure.

If the software settings didn’t help, there may have been a failure in the system component of the Android System or Google Play Services. Try clearing the cache of these services through the Apps menu → All Apps → Show System → Android System. Select “Clean” and restart the device. In extreme cases, if the problem appeared after the firmware update, a full reset may be required. Before that, make sure to back up the data in the Mi Cloud or on your computer, as all personal files will be deleted.

Frequently Asked Questions (FAQ)
Why do notifications only come after the screen is unlocked?
This is a classic sign of power saving, which freezes the network activity of the application while the screen is off, and you need to add the application to auto-start and select the battery mode "No restrictions".
How to make sure that the text of the message is not visible on the locked phone?
Go to Settings → Notifications and Status bar → Lock screen and select “Show notifications, but hide their contents.” Then you will see only the name of the application.
Does Bluetooth or NFC affect notifications?
These modules alone do not block notifications, however, if the phone is connected to a Bluetooth headset or watch, notifications can only be duplicated or displayed on the connected device, not on the smartphone screen.
What to do if notifications are missing after the MIUI update?
After major updates, permission settings may reset. Go through the checklist at the beginning of the article: check autostart, display permissions over other windows, and battery settings for each important application again.
