How to lower the curtain on Xiaomi phone: the complete guide

The problem with opening the notification panel, which is affectionately called the “curtain” among Android and MIUI users, can come at the most inopportune moment. Imagine that you urgently need to turn off Wi-Fi or switch tracks, but the top of the screen simply ignores your touches. It’s not just a minor inconvenience, it’s blocking access to key smartphone management functions. In Xiaomi and Redmi devices, this situation can be caused by both a software glitch of the shell and hardware problems.

Often, users panic, believing that the touchscreen is out of order and take the phone to the service center. However, in most cases, the solution lies in the wrong settings or the dead system process SystemUI. There are many ways to return the functionality of the notification panel without losing data. In this article, we will examine all possible causes, from simple interface bugs to complex application conflicts, and provide step-by-step instructions for troubleshooting.

We'll look at both standard reboot techniques and more advanced techniques, including the use of engineering menus and ADB debugging. It's important to understand that the MIUI (or new HyperOS) interface has its own features that distinguish it from pure Android. For example, locking the screen in your pocket or special gestures can affect the operation of the sensor in the upper zone of the display. Let's go through each aspect in detail so that you can quickly regain control of your device.

The main reasons for blocking the top panel

Before we go into action, we need to understand the nature of the problem. Most often, the inability to lower the curtain is caused by a software conflict. The MIUI shell is quite heavy and full of functions, which sometimes leads to unstable system processes. If the background process that is responsible for rendering the interface freezes, then any interaction with the top of the screen becomes impossible. This is a classic case when SystemUI stops responding to interrupts.

The second common reason is third-party applications. Some programs, especially those that require overlay rights over other windows (such as blue filters, memory clinders or launchers), can intercept touch event control. As a result, the system believes that the touch is designed for this application, not to call the system panel.

Hardware problems are less common, but they can't be discounted: If there's a crack in the top of the screen or a protective glass is glued with a violation of technology (a bubble of air in the sensor area), this can lead to "dead zones." In addition, static electricity or low battery power sometimes cause chaotic behavior of the touchscreen, in which cases software methods can only give a temporary effect.

⚠️ Note: If you notice that the curtain does not go down only in certain applications (for example, in games or video players), check the settings of these programs. Often, it activates Full-screen or Do Not Disturb mode, which hides the interface elements.

Basic methods of rebooting and resetting the interface

The easiest and often most effective way to fix the problem is to reboot the system. However, in the case of a hanging curtain, the usual method may not work if the touchscreen is partially unresponsive. Try to pinch the power button 10-15 seconds before the turnoff menu appears. If the screen reacts, select Reboot, which will forcefully terminate all processes and start SystemUI again, which often eliminates temporary glitches.

If the screen is not fully responsive to touch, but the buttons are working, use a key combination to force a restart. Most Xiaomi and Redmi models need to press both the power button and the Volume Up button at the same time. Hold them for about 10 seconds until the device vibrates and the Mi logo appears. This is the analogue of "battery pulling" and helps in 90% of software freezes.

There is also a softer method of restarting the interface without fully restarting the phone, but it requires access to the developer menu or using ADB. If you have the option to type a command (for example, via a voice assistant or an external keyboard), you can use the adb shell am kill com.android.systemui command.This will kill the interface process and it will automatically restart in a second. For ordinary users, this method can be tricky, but it is effective for advanced users.

After you restart, check the sensor, if the problem was caused by a temporary overflow of RAM or a driver conflict, it will disappear. However, if the curtain stopped lowering again after a while, it is worth looking deeper. Often the culprit is a specific application that runs along with the system.

Screen and lock settings in MIUI

The MIUI and HyperOS shells offer a variety of random press protection features that can interfere with normal operation, and it's worth checking the Mode in Your Pocket settings first. This feature uses a proximity sensor to lock the screen when the phone is in the bag. If the sensor is contaminated or closed with film, the system can think the phone is in your pocket and lock the top of the screen.

To disable this feature, go to Settings → Lock screen. Find “Mode in your pocket” and turn it off. It’s also worth checking the Pocket Mode settings in the Security section or through a Settings search. Sometimes cleaning the proximity sensor, which is usually located next to the front camera or in the top speaker, helps.

Another important option is “Increased Pocket Mode” or “Stunt Protection,” which can be activated in third-party launchers or themes. If you have recently installed a new design theme or font, try to return the standard settings. Unsupported themes can cause interface layout conflicts, which can shift the swipe area for the curtain or become inactive.

Don't forget One Hand Mode. On Xiaomi's big screens, it reduces the display area by shifting the content down. If this mode is activated incorrectly, the top of the screen may become inaccessible to the swipe. Turn it off in Settings menu → Additional settings → One Hand Mode.

Application Conflicts and Safe Mode

If the basic methods didn't work, there's a high probability that the third-party app is to blame. To check this, you need to run your smartphone in safe mode. In this mode, only Xiaomi and Google system applications load, which allows you to exclude the influence of third-party software. If the curtain falls normally in safe mode, then the problem is exactly in one of the applications you install.

To enter Safe Mode on Android, you usually need to press the off button and then hold the Turn Off or Reboot button on the screen for a long time until you are prompted to go to Safe Mode. On some versions of MIUI, this may work differently: When you boot your phone, when the Mi logo appears, press the volume down button.

While in Safe Mode, analyze which apps you have recently installed.

• 🛡️ Antiviruses and memory cliches that often have deep access rights.
• 🎨 Launchers and design themes that change the system interface.
• 🔆 Brightness control applications or blue filter.
• 📱 Task Managers and Batteries.

Remove suspicious programs one at a time, restarting the phone to normal mode after each deletion to identify the culprit. Often the problem is caused by “optimizers” that aggressively control processes and can block system functions.

⚠️ Warning: In safe mode, some features may not work properly and the internet may be shut down. That's OK.

Specific gesture and navigation settings

In modern versions of MIUI and Android, navigation management is divided into buttons and gestures. Curtain problems often occur when switching between these modes or using third-party navigation bars. If you have gestures enabled, try temporarily switching to the classic three buttons. This action reboots the navigation module and can restore the responsiveness of the upper zone.

Also worth paying attention to the settings of Full Screen for specific applications. MIUI has a feature that allows you to hide the camera notch (bang) or rounded edges of the screen by adding a black bar on top. If this setting is knocked down, the system may not correctly determine the boundaries of the workspace. Check this in the Settings → Screen → Cutout Control (or Full Screen).

Another nuance is the double-touch speed to turn on the screen. If this feature is set too sensitive, the phone may perceive the swipe down attempt as a series of taps to turn on the screen, creating a conflict of events. Try turning off "Double-touch to turn on/off the screen" in the lock screen settings.

💡

If you have gesture navigation enabled, try changing the sensitivity or the trigger area in the special feature settings. Sometimes shifting the swipe zone by 1-2 pixels solves the problem.

Check if the zoom feature is included in the special features, it's designed for the visually impaired and scales the screen with triple touch, and randomly activating this mode can make controlling the curtain extremely difficult, since swipes will be interpreted as zoom commands.

Touchscreen diagnostics and calibration

If you've run out of software, check the physical condition of the touchscreen. Xiaomi phones have a built-in hardware testing engineering menu. To get into it, open the Phone app and dial ##6484#. In the CIT (Customer Interface Test) menu that opens, select Touch sensor or Touchpanel.

In the test mode, swipe your finger around the perimeter of the screen, paying special attention to the top. The line should be drawn clearly, without breaks or jumps. If a line breaks or shakes in a certain area, this indicates a physical problem with the digitizer, in which case no settings will help - you need to replace the screen module.

Calibration is also often available on this menu, and if the test shows that the sensor is working but with errors, try calibrating. Follow the instructions on the screen: you usually need to press points in the corners and center. Once calibrated, the phone will restart, and the coordinates of the touches will be recalculated.

Don't ignore the state of the protective glass. Cheap glass may not have an oleophobic coating and work properly with multi-touch, but it often disrupts the electrostatics of the screen, especially in low humidity conditions.

Resetting and extreme measures

When none of these methods work, the radical but effective way is to reset all settings, not by deleting data (photos, contacts), but by returning system parameters to factory values, which eliminates errors in MIUI configuration files that may have been damaged during updates or crashes.

To perform the reset, go to Settings → About Phone → Settings Reset. Select Reset All Settings (not to be confused with Erase All Data). The phone will reboot and you will have to reset Wi-Fi, alarm clocks and ringtones, but your personal files will stay in place. This often solves interface problems.

If that didn't work, and the test on the engineering menu showed sensor problems, or if the phone fell/crippled, there's a possibility of hardware failure of the touchscreen plume. In this case, software manipulation is powerless. It's also worth checking for system updates. Sometimes Xiaomi releases patches that fix known touchscreen bugs in specific models.

⚠️ Warning: Before any reset (even settings), it is strongly recommended to back up important data to the Mi Cloud or your computer.

💡

If the reset and flashing didn't work, and the engineering test shows dead zones, it's a physical problem, and you need to replace the touchscreen or the display module at the service center.
