Xiaomi and Redmi smartphone owners often face a situation where the device interface stops responding to the usual actions of moving icons. The message that the desktop is protected from changes can take you by surprise, especially if you are used to changing widgets or removing applications. On the Xiaomi Redmi Note 9 model, this feature is built into the MIUI shell to prevent accidental removal of system shortcuts, but sometimes it blocks useful user actions.
Fortunately, solving this problem does not require deep technical knowledge or root rights. Most often, the reason lies in the activated lock mode, which is easily disabled through the launcher settings. In some cases, third-party themes or specific accessibility settings that conflict with the system interface are the culprits.
In this article, we will discuss all possible causes of locking in detail and offer step-by-step solutions for each of them, learn how to manage the lock screen settings and regain full control of your device.
Reasons for the appearance of the interface blocking
Understanding the nature of the problem is the first step to fixing it. The desktop protection feature was introduced by Xiaomi engineers not to annoy users, but to protect against random actions. However, the algorithms of this protection sometimes work too aggressively. The main trigger is the activation of a special switch in the launcher settings, which blocks any manipulation of the application grid.
Another common reason is the installed themes. Third-party skins often change the logic of the interface, and after they are used or removed, standard settings can get lost. It is also worth considering that some system updates to MIUI can bring with them changes in the logic of the settings menu, returning old locks by default.
⚠️ Warning: If the lock appears suddenly after installing a new application from an unreliable source, it could be a sign that malware is working that mimics system errors.
And the human factor is not excluded, because often users, when they hand the phone to their children or just hold it in their pocket, accidentally activate the lock function through the control panel or voice assistant, in which case the system simply executes a command, counting its intentional action.

Main method: setting up the system launcher
The most effective and safest way to remove protection is to use native shell settings, which works on all current MIUI versions installed on the Redmi Note 9. You don't need third-party programs, you need enough care when navigating the menu.
To start, open the standard settings menu for your smartphone. Find a section that may be called Desktop or hidden inside the Home category. Depending on the firmware version, the path may be slightly different, but the logic remains the same across Xiaomi's Android ecosystem.
Inside the menu, you need to find a change protection switch, which can be called "Model Lock," "Change Protection," or the like. Make sure the slider is in the "Off" position.
Once you do this, the system should react instantly, and try to pinch your finger on any icon -- if you have a vibration effect and an editing menu, you've solved the problem, and if the menu doesn't open, maybe a different layer of protection is active.
What to do if there is no item in the settings?
Sometimes carrier manufacturers or regional firmware versions hide this item. In this case, try changing the region in the settings (Settings -> Additional settings -> Region) to India or Singapore, rebooting the device and checking the menu again. Once unlocked, the region can be returned. Reset the launcher settings through the application menu If the standard path through the settings did not work, or the menu item is missing, you can use direct access to the properties of the system application. This method allows you to forcibly reset the desktop display settings without affecting the user's personal data. You will need to go to the application management section. It is important not to confuse it with Google Assistant or other shells. Inside the app menu, find the "Clear Data" or "Delete Data" button. Don't be afraid to press this button: your photos, contacts and installed applications will not disappear. Reset will only be the settings of the location of the icons, widgets and lock parameters. Action The risk of data loss switching off in the layout settings No Data Clearance Launcher Reset of the icons and widgets Low (disappear widgets) Resetting all to the device's backup to the screen, which is now a high-backing of the system. The impact of design themes and third-party launchers MIUI shell is famous for its customization capabilities, but it is the themes that often become a source of conflict. If you recently installed a new design from a theme store, the problem may be in its code. Some topics forcibly include desktop locking as part of their design. To test this theory, temporarily switch to a standard theme "Classic" or "Default." You can do this through the "Themes" application. After applying the standard design, reboot the device. If the lock is gone, then it was in the third-party theme code. Also worth paying attention to the launcher launcher or launcher systems installed on the Redmi launcher. Try temporarily disabling or removing a third-party launcher to see if it's causing the lock. If you can't get into settings because of the lock, try running the Security app (green lightning icon). Inside, there's an optimization feature that sometimes resets minor interface errors, including stuck lock states. Simple mode and special features There's a less obvious reason for blocking - Simple Mode activation. This interface is designed for older people or people with disabilities, and it by default forbids changing the structure of the desktop, including sticky lock states, and checks that the screen is not enlarged on the menu, and usually says "Simple mode." After leaving the simple mode full functionality MIUI Another hidden parameter is in the Special Options section, and the gaze control or voice control functions can sometimes block the touch screen to prevent false positives. Go through this settings section and make sure all experimental features are disabled. ⚠️ Attention: In simple task mode, removing system shortcuts is not intentionally allowed. Leaving this mode is the only way to return editing. Remember that the Xiaomi Redmi Note 9 has a Pocket Mode feature that locks the screen when the proximity sensor is closed. Make sure the security glass is glued correctly and does not cover the upper end of the smartphone, otherwise the phone will think that it is in your pocket, and block the input. 💡Most often, desktop locking is not a system error, but an activated protection feature that is easy to find in the launcher settings or reset through the application menu. Hardware problems and touchscreen repair In rare cases, a message of protection or the inability to move icons may indicate a physical malfunction of the touchscreen. If the screen reacts to latency, phantomite (self-presses) or does not respond in certain areas, the software methods will be useless. You can check the state of the sensor using the engineering menu. Enter the code # #6484## in the phone application. CIT (Customer Interface Test: Select the Touchpanel test and swipe all areas of the screen. The line should be continuous and smooth. If you find dead zones or chaotic line jumps during the test, it suggests that you need to replace the touchscreen or re-paint the plume, in which case the protection message may be an erroneous interpretation by the system of no clear input signal. And the problem can also be a cheap safety glass, which is too thick or static, and it can interfere with the normal operation of the digitizer, and remove the glass and check the screen without it, which will help to localize the problem. Can you remove the desktop system application? No, you can't delete or disable the system launcher on Xiaomi. This will cause the phone to be unable to display the interface after the reboot, and you'll see a black screen. If the launcher is damaged, it only needs to update or clear the data. Why after the update? MIUI There's a lockup again? When you update your firmware, the system often resets the launcher's custom settings to the factory settings. The factory default setting may include protection against changes. You'll have to go through the shutdown procedure again in the settings. Does the "Do Not Disturb" mode affect desktop operation? There is no direct effect on blocking icons, but it can hide notifications and limit some background processes, which is sometimes visually similar to the interface freeze. What if the screen does not respond to any touch? If the screen is not fully responsive, try rebooting with buttons (clamp Volume Up). + If that doesn't work, maybe the plume of the display has gone off or the battery has run out, and then you need to go to the service center, and can the virus block the desktop? Yes, some types of ad malware can block the interface, requiring payment or application installation.If you see suspicious windows that can't be closed, boot in Safe Mode (clip the off button on the lock screen) and remove newly installed questionable apps.
