Control over installed applications on a smartphone is a key aspect of digital security. Whether it’s protecting personal data from prying eyes, limiting children’s access to inappropriate content, or simply wanting to save battery power by blocking resource-intensive apps, Android’s capabilities allow you to flexibly configure access to software without third-party utilities. However, many users do not even suspect that built-in system tools can completely replace popular blocker applications such as AppLock or Norton App Lock.

In this article we will analyze all the available ways to restrict access to applications without root access and install additional software. From standard functions Android 12-14 to hidden capabilities of manufacturers like Samsung Knox or MIUI Second Space —you will learn how to set up the blocking as securely as possible. We will pay special attention to the nuances of working with different versions of the OS and brands of smartphones, where the interface may differ significantly.

1. Built-in function "Screen Time" (Digital Wellbeing)

Starting from Android 9 Pie, Google has integrated a tool Digital Wellbeing (in Russian localization - “Digital Wellbeing”) into the system. This module was originally created to control the time of use of gadgets, but its functionality allows you to either block application launching by timer or completely. The method works on all devices with pure Android and most proprietary shells (One UI, OxygenOS, ColorOS).

To activate the blocking:

  1. Open Settings → Digital well-being and parental controls.
  2. Select item Toolbar (or Dashboard in older versions).
  3. Find the application you want to limit in the list and tap on the hourglass icon (Application timer).
  4. Set a time limit (for example, 0 minutes for complete blocking) and confirm.

After activating the timer, the application will be blocked until the end of the day (or the selected period). An attempt to launch will result in an exceeded notification. limit. Important: this method does not require a passwordis therefore suitable only for self-control and not for protection from third parties.

💡

If you need blocking on a permanent basis, set the timer to the minimum value (1 minute) and turn it on daily through Settings → Digital well-being → Application timers

For users who want to limit access to applications on children's devices, the optimal solution is Google Family LinkThis service allows you not only to block individual apps, but also to set age restrictions and control purchases in Google Play, and also track the child’s location. The main condition is that both participants (parent and child) have a Google account.

Setup instructions:

  • 📱 Install Family Link on both devices (parent and child) from Google Play.
  • 👨‍👩‍👧‍👦 Create a family group in the application by adding your child’s account.
  • 🔒 Go to the section Manage applications and select those that you want to block.
  • ⏳ Set up time limits or completely prohibit launching.

Feature Family Link -opportunity remote blocking from the parent smartphone. For example, if a child has installed a new application, you will receive a notification and can immediately restrict access to it. However, keep in mind that children over 13 years old can leave the family group independentlyif they know the password for their Google account.

3. Locking through “Safe Mode”

A little-known but effective way to temporarily disable all third-party applications - starting Android in safe mode. loads only pre-installed apps, and all user software becomes unavailable. The method is suitable for emergency cases when you urgently need to restrict access to the device.

How to activate:

  1. Hold the button Power on switched off or locked screen.
  2. Hold your finger on the item Turn off (or Disable power) until a request appears to go to Safe mode.
  3. Confirm the action and wait for the reboot.

The message will appear in the lower right corner of the screen Safe Mode. To return to normal functionality, simply reboot the device. This method does not require passwords and works even if the graphic one is forgotten. key, but is not suitable for permanent locking —after exiting the mode, all applications will become available again.

What to do if safe mode does not turn on?

If after holding the power button the request for safe mode, try an alternative method: turn off the device, then turn it on, holding the button Reducing the volume until the system boots.

4. Manufacturer's proprietary solutions

Many brands add unique functions to their shells to block applications. Let's consider the most. common options for popular smartphone models.

Brand/Shell Lock function Path in settings Features
Samsung (One UI) App Lock (in composition Samsung Knox) Settings → Biometrics and security → Application blocking Requires PIN/fingerprint. Works with any applications, including system ones.
Xiaomi (MIUI) Second Space / Private mode Settings → Accessibility → Second space Creates a separate profile with its own applications Supports different passwords for each space.
Huawei (EMUI) PrivateSpace Settings → Security → Private space Full Isolation of applications and files. Requires a separate PIN.
Oppo/Realme (ColorOS) App Encryption Settings → Privacy → Application blocking Encrypts application data. Supports face locking.

Proprietary solutions are usually more reliable than standard Android tools, as they are integrated at the system level. For example, Samsung Knox uses hardware encryption, which makes bypassing the lock almost impossible without resetting the device. However, the interface and availability of functions may vary depending on the model and firmware region.

5. Limiting the background of applications (to save battery)

If the purpose of blocking is not security, but optimizing performance, you can limit the operation of applications in the background. This does not prohibit the launch of apps, but significantly reduces their activity when they are minimized. This method is useful for software that is constantly running. consumes battery or mobile traffic (for example, social networks or instant messengers).

How to set up:

  1. Go to Settings → Applications.
  2. Select the desired application and open Battery (or Battery usage).
  3. Activate the option Limit background activity (name may differ: Battery optimization, Sleep applications).
  4. For complete limitation, select mode Strict restriction or Deep sleep (in MIUI).

This method does not block the launch of applications, but significantly reduces their impact on battery life. For example, Facebook in strict restriction mode it does not will update the feed in the background, and Google Maps will stop tracking your location when minimized. Please note that some functions (for example, notifications) may not work correctly.

💡

Limiting the background is the best way to extend battery life without completely blocking applications. instant messengers, social networks and games.

6. Hiding applications from prying eyes

If blocking is not required, but you need hide apps from strangers (for example, banking apps or personal correspondence), you can use the hiding function. Most manufacturers offer such a tool in their shells.

Examples by brand:

  • 📱 Samsung: Settings → Home screen → Hide applications. Applications will remain in the menu, but will not be displayed on the main screen and in search.
  • 📱 Xiaomi: Settings → Applications → Hide applications. Requires setting a password to access the hidden list.
  • 📱 Huawei: Use Private space (see section 4) or the function Hidden applications in the launcher EMUI.

Hidden applications are not deleted or blocked - they simply become invisible in the standard interface. You can access them through a system search or a special menu (for example, swipe down on the main screen in MIUI). with locking through App Lock.

How to find hidden applications on Samsung?

To see hidden apps, open the application menu and make a gesture swipe down - a search bar will appear. Enter the name of the hidden application and it will appear in the results.

7. Alternative methods: ADB and third-party launchers

For advanced users who are ready to work with ADB (Android Debug Bridge), there is a method complete blocking of application launches at the system level. This method requires connecting a smartphone to a PC and knowledge of basic commands, but gives the maximum. control.

Step-by-step guide:

  1. Activate Mode Developer (tap 7 times on Build number to Settings → About phone).
  2. Enable USB debugging in the developer menu.
  3. Connect your phone to the PC and run the command: 
    adb shell pm hide com.example.app

    (replace com.example.app with the batch name of the application, for example com.facebook.katana for Facebook).

  4. To unlock use: 
    adb shell pm unhide com.example.app

This method irreversibly hides the application before executing the unlock command, but does not delete its data. Suitable for system applications that cannot be disabled using standard methods. Caution: incorrect use ADB can lead to system malfunctions.

Alternative for those who do not want to work with commands - third-party launchers like Nova Launcher or Apex Launcher. They allow you to hide applications from the menu without system changes, but do not block their launch through search or other launchers.

💡

ADB commands give the most profound control over applications, but require caution. It is recommended to create a backup copy before experimenting.

Common errors and how to avoid them

When setting up application blocking, users often encounter common problems and ways to solve them:

⚠️ Attention: If you are using Digital Wellbeing to block system applications (for example, Settings or Phonealways leave at least one way to unlock (for example, through Family Link or Safe Mode).

Problem 1: The lock is reset after reboot.

  • 🔄 Check if whether the mode is activated Guest space or Second user —it resets the settings when you exit.
  • 🔒 Make sure that a PIN/password is set on the device - without it, some blocking functions do not work.

Problem 2: The application continues to send notifications despite blocking.

  • 🔔 Disable notifications manually: Settings → Applications → [App name] → Notifications → Disable.
  • 📵 For MIUI and EMUI use Protected applications in the battery settings.

Problem 3: Does not work blocking on Android Go or outdated versions.

  • 📱 Update the firmware to the latest version (if possible).
  • 🛠️ Use third-party blockers from Google Play (for example, AppLock by DoMobile Lab), but consider the security risks.
⚠️ Attention: On devices with Android 8.0 Oreo and lower, the function Digital well-being may not be available. In this case, you will have to rely on the manufacturer's proprietary tools or third-party applications.
Is it possible to block system applications (for example, Play Store)?

Yes, but with reservations. System applications are blocked in the same way as regular ones, but this can disrupt the operation of the device. For example, blocking will lead to errors in other apps. It is safer to use proprietary tools like Digital Wellbeing System applications are blocked in the same way as regular ones, but this may interfere with the operation of the device. For example, blocking Google Play Services will lead to errors in other apps. Safer to use ADB or branded tools like Samsung Knoxthat allow you to selectively restrict access.

How to unlock an application if you forgot your App Lock password?

The methods depend on the blocking method:

  • For Samsung App Lock: use a backup PIN or reset via a Samsung account.
  • For Digital Wellbeing: reset the timer in the settings or wait until the end of the day.
  • For third-party blockers: try restoring access via the email specified during setup.

If all else fails, all that remains is resetting the device to factory settings (data will be lost!).

Will the locking work if you remove the SIM card or turn off the Internet?

Yes, all the methods discussed (except Google Family Link) work offline Locking via Digital Wellbeing, App Lock or ADB does not depend on the presence of a network or SIM card. The exception is functions that require verification via the Internet (for example, two-factor authentication in some blockers).

Is it possible to block access to applications by time of day?

Yes, for this purpose suitable:

  • Digital Wellbeing: set up a timer schedule for each application.
  • Google Family Link: set time limits for use.
  • Third-party applications like StayFocusd or ActionDash (require additional permissions).

For example, you can prohibit the launch of games from 22:00 to 7:00, leaving access to educational apps.

How to check which applications are blocking other apps?

Use the built-in activity monitor:

  1. Open Settings → Applications.
  2. Tap on the three dots in the upper right corner and select Special access → Access to use other applications.
  3. View the list of apps that can block or restrict other applications (for example, Digital Wellbeing, antiviruses).

If you suspect that the blocking is carried out by a virus, check the device through Google Play Protect (Settings → Security → Google Play Protect).
