Owners of Xiaomi smartphones and TVs often face a situation where the device interface stops responding to usual actions, and an attempt to change the settings leads to a message of ban. This phenomenon, known as desktop protection or screen locking, can be caused by various factors, from the activation of parental controls to system failures of the MIUI shell or Android TV. Understanding the nature of this lock is the first step to regaining full access to the functionality of your gadget.
In this article, we will look at all the possible causes of limitations and offer proven methods to address them. It is important to understand that some protections are built in by developers for data security, so turning them off requires a conscious approach. We will look at both software settings and hidden engineering menus that will help you regain control of the device.
Don't panic if your screen is locked or no longer responding to swipes. Most of the time, the problem is solved without going to the service center. The key is to act consistently and carefully monitor what permissions you give to applications during the setup process. Below are detailed instructions for various lock scenarios.
Reasons for the blocking of the interface on Xiaomi devices
The first thing to start with is to identify the source of the problem: Desktop protection can be activated not only by user actions, but also by background processes. The MIUI shell has many layers of security that sometimes conflict with each other, creating the illusion of a complete lockdown.
Often users accidentally activate Guide Access or Parental Control mode, forgetting about it after a while, and installing a third-party launcher or memory cleanup application that has received excessive administrator rights of the device can also cause the installation of a third-party launcher or a memory cleanup application that has received excessive administrator rights of the device.
In the case of Xiaomi TVs, the situation is often exacerbated by the features of the Android TV platform, where control is carried out by the remote, and accidentally pressing a combination of buttons can trigger kiosk mode or access restrictions, which can be understood by analyzing recently installed applications and changes in security settings.
- 🔒 Activate Parental Control in Google Play or Security Settings.
- 📱 System Launcher Failure or Conflict with a Third-Party Interface Installed.
- ⚙️ Administrator rights for malicious or incorrectly operating applications.
- 🔄 Errors after updating the operating system or resetting the settings to factory.
Why does the lock appear after the update?
Disable the lock via MIUI security settings
The most common method of removing restrictions is in the standard security menu, you need to go to Settings → Passwords and Security, and you should pay attention to Access to Device or Application Protection, which is where active restriction profiles are often hidden.
If you find an active restriction profile, the system will require input. PIN-The forgotten password can only be reset through the Mi Account account, if such a link was provided, or by completely resetting the device.
For TVs, the path may be different. You need to go to Settings → Security and Restrictions. Check if Guest Access or Child Profile Restrictions are enabled, and disabling these features will return full access to your desktop.
☑️ Checking security settings
Importantly, after the protection is turned off, it may be necessary to restart the device to apply the changes. If the standard settings do not help, it may be that the lock is caused by a third-party application that has embedded deeper into the system.
Management of special opportunities and administrator rights
One of the most insidious reasons for blocking desktops is applications that have been granted accessibility, which can intercept screen control by blocking touch or button pressing, and you can check the list of such applications by Settings → Advanced Settings → Special features.
In this menu, carefully review the list of services included. If you see an unfamiliar application or program that was recently installed before the problem appeared, immediately disable it. Often, miners or aggressive optimizers use these rights to block the interface.
Also worth checking is the "Device Administrators" section, which is usually in the security menu or in the settings search, and it lists applications that have the right to lock the screen, remotely reset or delete, and deleting the rights from suspicious programs often solves the problem instantly.
⚠️ Note: Do not disable system services such as “Find My Device” or «MIUI Security" if not sure of their purpose, this can lead to the loss of the ability to track the device or disrupt the antivirus.
Once the administrator rights are revoked, it is recommended that you delete the app completely. Go to Settings → Applications → All Apps, find the program, and select “Delete.” If the delete button is inactive, then the administrator rights are still active.
Using Safe Mode for Diagnostics
If the desktop is locked and you can’t get into settings, an effective diagnostic method is to run in Safe Mode. This mode only downloads system applications, which allows you to exclude the influence of third-party software. On Xiaomi smartphones, this is usually done with a long press of the turn off button on the desktop, after which you have an offer to go to Safe Mode.
On Xiaomi TVs, the method may be different: it often helps to download with a button pressed “Menu” or “Back” on the remote when the power is turned on. If the lock is gone in safe mode, then the problem is guaranteed in a third-party application.
While in Safe Mode, you can safely uninstall recently installed programs or launchers. Once you remove the problem software, simply restart the device in the usual way to exit diagnostic mode.
| Type of device | Entry method | Operation in mode | Getting out of the regime |
|---|---|---|---|
| Xiaomi Smartphone | Long tap "Switch Off" on the screen | Removal of suspicious applications | A normal reboot. |
| TV Mi Box | Click "Back" when switching on | Resetting launcher settings | Rebooting the remote |
| Pad tablet | Volume button combination | Disabling access rights | System restart |
💡
If the buttons on the screen don’t respond, try connecting. USB-mouse to smartphone OTG-This will allow you to control the interface and remove the blocking application, even if the sensor is not working.
Resetting and extreme measures
When software methods fail, you have a full reset, which will return the device to factory status by removing all user data, photos and apps, and make sure you have a backup of important information in the Mi Cloud or on your computer before doing this.
To reset the recovery menu on the device that is off, press both the power button and the volume button. In the volume buttons that appear, select Wipe Data and confirm the action with the power button.
On Xiaomi TVs, resets can often be done via a combination of buttons on the remote (usually a “Back” button and a settings menu call button) when power is off, holding them while they are turned on. Also, the reset option is available in the Settings → About Device → Reset if the interface is at least partially responsive.
⚠️ Warning: After a reset, the device can request a Google or Mi Account account that was previously synced (FRP). Make sure you remember your login and password.
Using the engineering menu through code ##6484## (CIT) can also help diagnose hardware problems of buttons or sensors that the user may mistaken for software locking. If tests show a touchscreen malfunction, the software methods will be useless.
Prevention of re-blocking
To keep the problem from returning, you need to follow certain digital hygiene rules, first of all, do not install applications from unknown sources. APK-files often contain code that requests administrator rights and blocks the device to impose ads.
Check the list of special rights apps regularly, it’s helpful to go to the special features settings once a month to check if anything is out there, and it’s also advisable to keep the system updated, as security patches close down vulnerabilities exploited by viruses.
Set up automatic blocking of unwanted content via Google Family Link or built-in MIUI parental controls if children are using the device, creating a controlled perimeter within which random activation of the desktop lock will not be possible.
💡
Regularly checking the access rights of applications and installing software only from the official Mi GetApps store or Google Play reduces the risk of blocking to a minimum.
