The issue of missing notification curtains on Xiaomi smartphones running MIUI 12 has become one of the most common user complaints since the update, made worse by the fact that standard panel recovery methods (reboot, reset gesture settings) often fail due to firmware features. In this article, we will look at 5 proven ways to return the curtain, from basic settings to advanced methods using ADB and editing system files.
It is important to understand that the reasons for the loss can be different: it can be a failure after the MIUI update, and conflicts with installed themes, and even hardware problems (for example, a sensor malfunction).We will focus on the software solutions that work on most Xiaomi, Redmi and POCO models with the 12.x shell version. If you encounter this problem on the newer version (MIUI 13/14), some methods will also remain relevant.
Before proceeding with the instructions, make sure that:
- π You have restarted the device (sometimes holding the power button 10 helps).+ second-on-seconds).
- π± The phone has enough charge (minimum 30%) β this is critical for methods with a high-powered cell phone. ADB discharge.
- π You have a backup of important data (in case of resetting settings).
1. Check the basic settings of MIUI 12
Often, the notification curtain is lost due to randomly changed settings in the system settings. Start by checking the following points:
Open Settings β Display β Full-screen mode. Here you should be active options:
- π± Show notification curtain β the switch must be switched on.
- π Guests for curtain - select the "Swipe down" option (if available).
- π¨ Notification style β try changing to βClassicβ or "MIUI".
If these settings are already correct, go to Settings β Applications β Application Management β System Applications and find the Notification Panel (or System UI). Slip on it, select Storage β Clear the cache and restart the device. This method helps in 30% of cases when the curtain disappears after installing themes or updates.

If there is no βNotification Panelβ in the list of system applications, try to find com.android.systemui through a search in the application settings.
2. Reset gesture settings and animations
In MIUI 12, the control gestures often conflict with the display of the curtains.
- Go to Settings β Display β Additional β Full-screen mode.
- Select Reset gesture settings (or turn off full screen mode temporarily).
- Return to Settings β About Phone β MIUI version and tap 7 times on the line with the version to activate the developer mode.
- Go back to Settings β More β For developers and find:
| Parameter | Recommended value | Note |
|---|---|---|
| Window animation | Off or 0.5x | Accelerates the curtain response |
| Animation of transitions | Off or 0.5x | Eliminates delays |
| USB debugging | On. | Needed for methods with ADB |
| Do not turn off the screen when charging | On. | Helps with testing. |
After applying the changes, restart the device. If the curtain does not appear, proceed to the next method.
Turn off full screen |Activate developer mode |Switch off animations |Reboot phone |Check the curtain after downloading-->
3. Recovery through ADB (for power users)
If the standard methods do not work, you can use them. ADB (Android Debug Bridge requires a computer and USB-cable, but is effective in 80% of cases.
First, download Platform Tools from the official Android website and unpack the archive.
- Connect the phone to the PC and allow debugging over USB (a request will appear on the smartphone screen).
- Open the command line (Windows) or terminal (macOS/Linux) in the folder with the platform-tools.
- Enter the command to check the connection: Adb devices must appear serial number of your device.
- Run System UI Reset Command: Adb shell cmd package compile -m speed-profile -f com.android.systemui
- Reboot your phone: adb reboot
If the curtain does not appear, try an alternative command:
adb shell pm clear com.android.systemuiWhat if the ADB canβt see the device?
Critical: Don't interrupt the execution ADB-commands and do not disconnect the cable during the process - this can cause system failure.
4. Manual editing of the build.prop file
This method is suitable for users with unlocked bootloader and root rights. It involves editing the system file build.prop, which contains the shell configuration.
Warning: Incorrect editing may cause the device to fail. Make a backup copy of the file before making changes!
β οΈ Warning: Changing build.prop without a backup can cause bootloop. Use this method only if you are confident in your actions.
Instructions:
- Install a file manager with root support (such as Root Explorer or Solid Explorer).
- Go to /system/build.prop and open the file in the text editor.
- Add a line to the end of the file: qemu.hw.mainkeys=0 This command forcibly turns on the program navigation buttons, which often restores the curtain.
- Save the file, set the rights to 644 (rw-r--r---) and restart the device.
If the curtain does not appear after the reboot, try adding another line:
ro.miui.has_real_bl=15. Reset to factory settings (last chance)
If all the previous methods didn't work, it's a hard reset, and it'll delete all the data from the device, so first, you can:
- π Make a backup copy through Settings β Additionally. β Backup and reset.
- π Make sure you know the username/password from your Mi Account (required after resetting).
- π± Remember or write down. IMEI phone (in case of network problems after resetting).
For discharge:
- Go to Settings β About the phone β Reset settings.
- Select Reset All Settings (not to be confused with Reset Network Settings).
- Confirm the action and wait for the reboot (may take 5-10 minutes).
After discharge:
- π Do not restore data from the backup immediately β first check the curtain.
- π₯ Install updates MIUI through settings β Update of the PO.
- π¨ Do not install third-party themes or launchers in the first hours after resetting.
π‘
Factory reset eliminates 95% of software problems with MIUI, but requires a complete reconfiguration of the device.
Alternative solutions and temporary workarounds
If neither method has returned the curtain, try:
- π§ Install an alternative launcher (like Nova Launcher or Lawnchair).Some launchers have a built-in notification bar.
- π± Use a gesture for quick settings: swipe down the right edge of the screen (sometimes works even if the curtain is not visible).
- π Reverse to the previous version MIUI via Fastboot (instructions are available on the forum Xiaomi.eu).
For POCO models with MIUI for POCO, switching to standard MIUI via the Themes app can help:
- Open the themes β My β Settings β MIUI type.
- Select "Standard MIUI" instead of "MIUI for POCO".
- Reset the device.
