How to disable Control Center on the lock screen Xiaomi

Modern Xiaomi smartphones, which use MIUI or HyperOS shells, offer users a wide range of features to quickly access settings. However, one of the most vulnerable areas in terms of privacy remains the ability to call the Control Center (curtain) directly from the lock screen, a feature designed to provide comfort, often causes random changes in settings, such as turning on mobile Internet or changing the brightness when the phone is in your pocket.

Moreover, having access to the curtain from a locked screen poses a potential security threat, which an attacker or an outsider can use to activate flight mode, turn off Wi-Fi or even access the control of a smart home if the corresponding widgets are displayed on the main screen of the control center, which is why the question of how to limit the functionality of the device in a locked state becomes relevant for many owners.

In this article, we will discuss in detail all available methods to limit access to system functions. You will learn what settings you need to change in the security menu, how to use the Kiosk mode for maximum restriction, and what features different firmware versions have. Completely turning off the curtain from the lock screen without locking the entire interface in standard MIUI settings often requires a comprehensive approach. Let's look at the algorithms of actions that will help you secure your device.

Risks of using a curtain on a locked screen

Many users underestimate the possibilities that come with simply swiping down a locked display. Standard behavior suggests that the device owner wants quick access to a flashlight, calculator, or track switching, but the same logic works against the owner in situations where the phone falls into the wrong hands or is physically exposed.

One of the main threats is the ability to disable geolocation or data transfer. If you use the search function of the device or remote control, activating the flight mode through the curtain will make these tools useless. In addition, in some versions of the shell, you can start debugging mode through quick settings or access a list of recent applications, which can reveal information about your activity.

⚠️ Note: On older versions of Android and MIUI In the notification center, you can sometimes respond to messages or even see the content of notifications from banking applications if you didn’t have additional content protection enabled.

There is also the risk of so-called "pocket set" or "pocket interaction." A phone in tight jeans can respond to touching fabric by mimicking swipes, resulting in unnecessary battery-discharge features being accidentally turned on on on the device as you walk down the street, or critical network settings being altered.

• 📉 Internet shutdown risk: An attacker can isolate the device from the network, which will prevent the coordinates from being sent.
• 🔦 Accidental activation of functions: A flashlight or alarm can drain the battery at the most inopportune moment.
• 🔓 Bypass locking: In rare cases, through the multimedia curtain menu, you can access the player control, which is an attack vector.

Understanding these risks encourages users to find ways to limit functionality, but it is worth considering that completely blocking the interface can reduce usability, for example, if you need to quickly check whether the alarm is on, or to start the flashlight urgently, the lack of access to these elements can be a problem.

Configure notification access and control panel

The first step to improving security is to fine-tune what is displayed on the lock screen. Android and Xiaomi’s shell allow you to flexibly manage the visibility of items. While there may not be a direct “Deactivate the curtain on the lock screen” button explicitly, limiting the content displayed will achieve a similar result.

To start, you need to go to the basic settings of the device. Find Settings → Notifications and Status bar → Lock screen. Here are the key switches that affect how much information the person who does not unlock the phone sees. Disabling the display of the contents of notifications is the first barrier to protection.

Next, look at the security section. Settings → Passwords and Security → Privacy often contains settings that prevent access to data on a locked screen. Some users mistakenly believe that setting a password completely solves the problem, but without the correct configuration of the interface, the curtain remains available.

It is also important to check the floating window and sidebar settings, which are sometimes accessible even when the device is locked, if certain gestures are activated. Disabling these features in the special features menu will help close unnecessary loopholes. HyperOS emphasizes the visual component, so the controls can be more noticeable than in the classic MIUI.

Remember, the changes take effect immediately. Once you have set up each item, it is recommended to lock the screen and check the result. If the curtain is still called but empty or does not contain critical switches, then the basic protection is set up correctly.

Use of the Kiosk mode for complete restriction

If standard measures are not enough and a severe limitation of functionality is required, for example, when transferring a phone to a child or a third party, the ideal solution is the Kiosk mode (or “Application Lock” in older versions), which allows you to lock the device on one particular application, making it impossible to log in, including calling the control center.

To activate this feature, go to Settings → Apps → In-app Lock (or search for Kiosk Mode). Here you will need to select an application that will work in the background or become the only one available. Once the mode is turned on, navigation buttons and gestures are blocked, and the attempt to swipe to call the curtain is ignored by the system.

Kiosk is particularly useful in situations where the phone is used as a navigator, payment terminal or media player, in which state the Control Center is completely unavailable, as the application interface overlaps the system layers, ensuring that no one can change the network settings or run other programs.

In some corporate or educational use cases, Xiaomi allows you to create limited user profiles where access to system settings is prohibited at the account level, a more complex but more reliable method.

• 📱 Fixing on a single screen: The user cannot fold the application or access the desktop.
• 🚫 Blocking system buttons: Volume and power buttons can be reconfigured or disabled.
• 🔒 Password protection: exit from the mode is possible only after entering PIN-code or pattern lock of the owner.

This mode is addictive because it changes the way you interact with the device, but for maximum security and to prevent unauthorized access to the curtain, it is the most effective software solution.

Blocking through special features settings

Android users have a powerful but often overlooked tool, customizations for special features, which, while designed for people with disabilities, can be adapted to limit random activities, such as screen-control features.

One of these features is “One-touch management” or “Enhanced dialogue.” By turning on certain filters, you can ensure that swipes in certain areas of the screen (for example, at the top of the status bar) will be ignored. The path to these settings is usually: Settings → Additional settings → Special features.

Be careful here. Incorrectly configuring interaction filters can make the phone virtually unusable, blocking not only the curtain, but also the necessary functionality, so before making changes, it is recommended to create a restore point or simply be ready to reset the settings.

⚠️ Warning: Do not include features that say they can overlap other applications if you are not sure of the consequences.

Also in this section, you can find Easy Control Mode, which changes the interface to a larger and simpler one, often removing unnecessary controls from the start screen and, in part, restricting access to system areas, which is a good option for older people or children.

Some Xiaomi models allow you to assign actions to long presses of volume buttons. Check this setting in the special features menu. If there is an action associated with calling a menu or assistant, it is better to turn it off to avoid accidental activation through the case or in your pocket.

By experimenting with these settings, you can find a balance between convenience and security, and the key is to test each change right away to make sure it works exactly as you intended and doesn't block the features you need.

Features of work in HyperOS and MIUI 14

With the release of HyperOS and the upgrade to MIUI 14, Xiaomi has redesigned many system processes, including notification management and control center, not only visual style, but also security logic.

In HyperOS, the control center was visually separated from the notification center, which led to two separate swipe zones: on the left, the swipe opens the notifications, and on the right, the control center, which allows for more flexibility in setting up access. You can, for example, allow notifications to be viewed, but completely deny access to the control center on the right.

To adjust this behavior in new firmware versions, go to Settings → Notifications and Status bar → Control Center. You can choose a style (old or new) and, more importantly, adjust the display of elements. In some regions and versions of the software, the option “Require unlock for the control center” has appeared, which perfectly solves the problem voiced.

The new versions also have more widget control, and if you have smart home widgets added to your control center, they can even be displayed on a locked screen if you don't have access rights set up. HyperOS recommends checking the settings of each widget separately by going to the Home app and checking the access rights for the lock screen.

It is worth noting that in the latest security updates Xiaomi has implemented a feature that blocks the security of the device. USB-access and debugging if the device has been rebooted and not unlocked, and this indirectly affects the system menus, making them less susceptible to external commands through a locked interface.

Additional protection measures for the device

Beyond software settings, there are other ways to minimize the risks associated with accessing the interface, and a comprehensive approach to security includes not only software settings, but also usage habits, as well as additional security tools.

One effective measure is to use locker applications that layer an extra layer over the lock screen, which can block any touches of the screen before you enter an additional password, a radical method, but it ensures that neither the curtain nor anything else is called.

Also worth considering is the possibility of setting behavior patterns, such as the habit of swiping the curtain down and back before locking the screen to reset the system state, or turning off sensitive switches, which, while it requires discipline, reduces the likelihood of accidental activation.

💡

Use Pocket Mode in your lock settings if it's available in your model.It uses a proximity sensor to ignore touches when the phone is in your pocket or bag.

Keep in mind physical protection: A high-quality oleophobic-coated protective glass not only protects the screen, but also reduces the likelihood of false touchscreens from moisture or static electricity that can mimic swipes.

Regular system updates are another important aspect: Xiaomi is constantly closing vulnerabilities that can be accessed without authorization, and if your version of MIUI has a bug that allows you to bypass the lock through the curtain, most likely, the security update has already fixed it.

In conclusion, completely disabling the control center on the lock screen requires a combination of privacy settings, the use of special modes and attentiveness to updates, and following these recommendations will significantly improve the security of your data.

💡

The optimal strategy is to disable the display of the content of notifications in combination with activation of the “Kiosk” mode when transferring the phone to third parties.
