In 80% of cases, the problem can be solved without resetting to factory settings – just know where to look.

In this article, we will discuss 5 proven ways to return the curtain to Redmi 9, including recovery through settings, rollback updates and hidden MIUI features.

Why the notification curtain on Redmi 9 is missing

The reasons for the disappearance of the notification panel on Xiaomi Redmi 9 fall into two categories: software and hardware, in the first case, the system or software settings are to blame, in the second – physical damage to the display or touch module.

Among the most common reasons:

  • πŸ”„ Update MIUI β€” New firmware versions sometimes reset gesture settings or conflict with the shell.
  • πŸ‘† Incorrect gesture settings – if you turned on full screen without considering swipe zone.
  • 🦠 Virus software – some applications block system elements of the interface.
  • πŸ”§ Resetting settings – after returning to factory parameters, the curtain may not automatically recover.
  • πŸ’₯ Fall or impact – physical damage to the sensor at the top of the screen.

Before you start rebuilding, check the screen's response to the touches at the top, if the sensor doesn't work only in the curtain area, it's more of a hardware problem, and if the panel doesn't open either by swiping or by the Power button, it's the software.

Method 4: Manual editing of system files (for advanced ones)

If standard methods don’t work, you can try to restore the curtain through editing the build.prop file. This method requires superuser rights (root) and is only suitable for advanced users.

Instructions:

  1. Install a file manager with root support (such as Root Explorer or Solid Explorer).
  2. Go to /system/build.prop.
  3. Find qemu.hw.mainkeys=0 and replace it with qemu.hw.mainkeys=1.
  4. Save the changes and restart the phone.

If you don't have a line, add it to the end of the file, and check for parameters.

ro.miui.has_real_bl=1


ro.miui.has_handy_mode_switch=1

  • πŸ”„ Restart the device manually (not via a soft reboot).
  • πŸ“± If the curtain does not appear, return the original values and try method 5.

  • πŸ”§ Display plume damage – even after falling without visible cracks, contacts could move away.
  • πŸ“± Touch Layer Fault – The top of the screen may not respond to touch.

  2. Try opening the notification bar through the voice assistant (say β€œOK Google, open notifications”).
  3. If you don't have a reaction, go to the service center, and the average cost of repairing a sensor on a Redmi 9 is 2,500-4000. β‚½.

Before the service visit:
