Xiaomi smartphone owners often face the need to limit the functionality of the device, especially if the gadget is used by children or the elderly. Accidental download of games, advertising software or malware can lead to memory filling, performance loss or even identity theft. Understanding how to prohibit the installation of applications on shaomi, becomes a key skill for digital hygiene and security.
Operating system MIUI And its modern version, HyperOS, provides users with powerful built-in access control tools, and unlike many other shells, it has a flexible rights system that allows you to block not only the launch of programs, but also the process of installing them from unknown sources. This is especially true in circumstances where APK-files are distributed through browsers or messengers.
In this article, we will take a look at all the restrictions available, from simple menu settings to specialized profiles, how to create a safe environment for a child, block the installation of questionable software, and monitor what permissions new software gets, and properly configuring these settings will save your device from a host of potential problems.
Use of Parental Control in Google Play
The easiest and most effective way to restrict the installation of applications on an Android device is to use the built-in tools of the Google Play Store. PIN-The code that will be requested whenever you try to download or update a program, and without knowing that code, you can't do it, which is perfect for protecting against children.
To activate the protection, you need to open the store app, go to the profile settings, and select Parental Control. Once you turn on the system, you will be asked to create a four-digit pin code. It is important to choose a combination that the child can not easily guess or peek, and then you can adjust the filters by age or completely prohibit the installation of games and applications of certain categories.
- 🔒 Open Google Play and click on the profile avatar in the corner.
- 🔒 Select "Settings» → «Family» → «Parental control».
- 🔒 Come up with a reliable one. PIN-code and confirm it.
- 🔒 Set age limits or prohibit installation completely.
It is worth noting that this method protects only from downloading through the official store. APK-So for comprehensive protection, you need to combine this method with other system constraints, which we'll talk about below.
Blocking the installation from unknown sources
The main channel of penetration of unwanted software on Xiaomi smartphones is the installation of packages outside the official store. Android defaults to block such actions, but many applications (browsers, messengers, file managers) can request permission to install other programs, your task is to revoke these permissions from all suspicious applications.
To find these settings, go to the security menu. MIUI The path may be slightly different, but the logic remains the same. You need to find a privacy section or a special protection section. APK-file.
⚠️ Note: If you see that the installation permission from unknown sources is available to a browser (such as Chrome or Mi Browser) or file manager, immediately disable it.
The process of disabling rights is as follows:
- Open the smartphone settings.
- Go to Privacy Protection (or “Privacy”).
- Find the Special App Access (Special App Access) option.
- Select Install Unknown Applications.
- Go through the list and make sure the switches are turned off for all programs except those you trust 100%.
This measure significantly improves the security of the device, and even if a virus or ad module tries to download additional software, the system will block this process at the permission level, and the user will receive a notification that the action is prohibited, which will allow you to respond to the threat in time.
💡
Check the list of applications with the “Install Unknown Applications” rights regularly. After system updates or installing new programs, this list may change, and permissions may appear again.
Restriction of installation through “Security” and antivirus
MIUI and HyperOS firmware preinstalled a system application called Security that runs deeper than standard Android settings, including antivirus and real-time protection that can block the installation of potentially dangerous applications before the process begins.
To maximize efficiency, you need to activate all layers of protection. Open the Security app, go to the settings (cog icon) and find the Antivirus section. Here you should turn on the option “Check on installation”. When you are actively scanning, the system will analyze the installation file and, if you detect threats or certificates do not conform, will issue a warning or completely block the action.
Also in this section, you often see the "Installation Control" feature, and if you turn on this option, you try to run it. APK-The file system will require confirmation through the fingerprint scanner, Face ID This creates an additional barrier that you can't get around without physically accessing the unlocked device and knowing the owner's biometrics.
| Protection function | Where to find out. | Efficiency | Impact on work |
|---|---|---|---|
| Google Parental Controls | Google Play → Settings | High (for Play Market) | Requests PIN when downloading |
| Blocking of Unknown Sources | Settings → Confidentiality | Critical (basic protection) | Blocking APK from the outside |
| Antivirus MIUI/HyperOS | Security annex | Medium/High | Scan files before installation |
| Imprint locking | Security settings | Maximum | Requires biometrics for each installation |
Creating a second space for sharing access
Xiaomi’s unique feature is its Second Space feature, which allows you to create virtually two independent profiles on a single device, like two different phones, ideal if you want to give a phone to a child or employee, but you don’t want to ban the installation of apps completely, you just want to isolate them from your data.
Second Space creates a separate desktop, your accounts, and your settings, and you can set this profile so that your Google account is not entered, and app installation is limited to an approved list, and you can switch between spaces using a fingerprint or password, which makes the system very user-friendly and secure.
To create a second space:
- 🚀 Go to Settings and find the "Second Space" item».
- 🚀 Click “Enable Second Space” and follow the instructions of the setup wizard.
- 🚀 Create a separate password or tie another finger to log in.
- 🚀 Set up a new space as a “children’s” or “guest” space without adding payment cards.
Key advantage: Even if malware or games are installed in the second space, they won't be able to access your photos, contacts and banking apps in the main profile.
☑️ Set up a safe profile for the child
Block access to settings through “Access with the App”
There's a more advanced, guerrilla method that allows you to block access to the settings of your phone, where restrictions are usually turned off, and the essence of the method is to use the App Lock function, and if you block access to the settings menu with a password, no one can change the security settings without your knowledge.
This can be done through the standard application protection feature in MIUI/HyperOS. It usually hides system processes, but they can be activated through special codes or developer mode (although in newer versions this is made more difficult for security), however, there is an easier way - using third-party launchers or blocking applications that impose a password to run any selected programs, including Settings and Package Installer.
If you choose to use a third-party blocker (like AppLock), make sure it is given maximum rights, including the right to draw over other windows and work in the background. In the locker settings, select Package Installer and Settings. Now, when you try to start the installation or change the settings, the phone will require a password.
⚠️ Warning: Be careful when blocking system applications. If you forget the password from the locker or delete it, you may lose the ability to control the phone. Always leave one unlock method (such as the pattern lock of the phone itself) active.

Use of the "Guest" mode for temporary access
If creating a separate space seems too complicated and giving full access to your profile is scary, use the Guest mode. Unlike the second space, the guest profile is completely erased when you leave it, which means that any installed apps, saved passwords and browser history will disappear as soon as you switch back to your account.
Guest mode is ideal for situations where you need to give someone a phone for a short time (call, see a map, take a photo), but you do not want the person to start installing their apps. The guest profile by default does not have access to your data, and installing heavy games or questionable software will not cause long-term harm to the system, since after the session everything will be deleted.
You can activate guest mode through the notification curtain (swipe down twice) or in the user menu in the settings. This is a fast and “one-time” way of protection that does not require deep configuration of the system.
💡
Guest mode is a temporary solution: all installed applications and data will disappear immediately after leaving the profile, which guarantees the purity of the system.
