How to block applications on Xiaomi Redmi Note 8 Pro: all ways to protect

Xiaomi Redmi Note 8 Pro is one of the most popular devices of the brand, but even it is not immune to prying eyes. Have you ever given a phone to a colleague to show a photo, and after a minute you find that it is leafing through your messages on WhatsApp or Telegram? Or worrying that a child will accidentally delete important files from the Gallery? In this article, we will analyze all the available ways to block applications on the Redmi Note 8 Pro β€” from standard MIUI functions to hidden features.

It's important to understand that app blocking is not just about privacy, it's also about data security. For example, if you store passwords from banking apps in notes or messengers, they can be leaked, and we'll look at the methods that work on MIUI 12, 13 and 14, and we'll also get around the common bugs that might make it go wrong. Some ways will require superuser rights, but most are available without them.

1. Built-in application locking via Second Space

The MIUI Second Space feature allows you to create a separate account on your phone with your own apps and data, not just blocking, but rather isolating your personal data from prying eyes, and the advantage of the method is that you don't need to install third-party programs, and the disadvantage is that you have to duplicate some applications.

How to set up:

  • πŸ“± Open the Settings. β†’ Special facilities β†’ Second Space.
  • πŸ”‘ Create a password for the second profile (it may differ from the main one).
  • πŸ“₯ Select the apps you want to hide (e.g. Gallery, Messages).
  • πŸ”„ Switch between swipe profiles down the lock screen (you need to enable in the settings).

⚠️ Attention: Second Space doesn't sync notifications from the main profile, and if you're interested in getting alerts from Viber or Slack, this method won't work.

πŸ“Š How often do you give your phone to other people?
Never.
Rarely (once a month)
Frequently (several times a week)
Constantly (daily)

2. Password blocking of applications (App Lock)

The most obvious way is to use the built-in App Lock feature, which is the default feature in MIUI, and allows you to put a password, fingerprint or facial recognition on any application, but many users encounter a bug when the lock is reset after rebooting the phone, and you can fix this by updating MIUI to the latest version.

Step-by-step:

  1. Go to Settings β†’ Applications β†’ Blocking applications.
  2. Click Enable and set a password (we recommend using a combination of numbers and letters).
  3. Select apps from the list (for example, Instagram, Bank, Photos).
  4. Activate Hide Notifications so that the contents of messages do not appear on the lock screen.

Remember your password or write it down in a safe place.

Check the MIUI version (should be at least 12.5)

Turn off autocleaning cache for system applications

Synchronize fingerprints if you use biometrics-->

⚠️ Note: If you forget the password from App Lock, you can only reset it through a full phone reset (Settings) β†’ The phone. β†’ Resetting settings.This will delete all data, so back up in advance to Mi Cloud.

3. Hiding apps from the menu (without deleting)

If you don't want to lock things hard, but you just want to take apps out of your sight, MIUI has an icon-hiding feature, which is useful for games that are distracting, for example, or for system utilities that you rarely use, and the hidden app won't show up on the menu, but it will stay on the system and be available through search.

How to hide the application:

  • πŸ” Press the app icon with your finger on the home screen.
  • 🚫 In the menu that appears, select Hide (or Remove from the screen in new versions). MIUI).
  • πŸ”Ž To return the application, open Settings β†’ Annexes β†’ Application management β†’ Hidden applications.

App Lockβœ… Yes.βœ… Yes.βœ… Yes.
Second Space❌ No (mainly profile)❌ No.βœ… Yes.
Disconnection (for system)❌ No.❌ No.❌ No.

πŸ’‘

If you need to launch a hidden app urgently, use Google Assistant, and say, "OK, Google, open [app name]," and it will open without even displaying the icon.

4. Blocking through third-party applications (without root)

If you don't like standard MIUI methods, you can use third-party software, such as DoMobile Lab's AppLock or Norton App Lock, which offer additional features such as:

  • πŸ” Geolocation blocking (for example, automatically block TikTok at work).
  • πŸ“Έ Hidden camera (takes a photo of someone trying to break the lock).
  • ⏱ Temporary blocking (for example, blocking games from 21:00 to 7:00).

⚠️ Note: The side of the application to block may conflict with MIUI, Especially if you have battery optimization on, to avoid spontaneous unlocking:

  1. Add a blocker app to the optimization exceptions: Settings β†’ Battery β†’ Battery Optimization β†’ Select apps.
  2. Turn off automatic cache cleaning for it.
  3. Update the app to the latest version (Play Market often releases patches for newer versions of MIUI).
What applications can not be blocked by third-party programs?
Do not block system utilities such as Settings, Phone or Messages. This can lead to a reboot cycle or loss of functionality. Also avoid blocking Google Play Services - this will cause account sync errors.

5. Blocking through ADB (for advanced users)

If you're willing to dive into the technical details, you can block applications through ADB (Android Debug Bridge), which doesn't require root, but requires connecting the phone to a computer, and the advantage is that locking works at the system level and doesn't reset after updates.

Instructions:

  1. Download Platform Tools from the official Android Developers website.
  2. Turn on USB Debugging on your phone: Settings β†’ About Phone β†’ MIUI version (click 7 times to become a developer), then Settings β†’ Additional β†’ Developers β†’ Debugging over USB.
  3. Connect the Redmi Note 8 Pro to your PC and execute the command: adb shell pm hide com.example.app (replace com.example.app with the batch name of the app, for example, com.whatsapp for WhatsApp).
  4. To return the application, use: adb shell pm unhide com.example.app

⚠️ Note: Not all applications can be hidden through ADB. For example, system utilities (Settings, Contacts) may not be blocked, and after resetting, all changes through the system can be made. ADB will be lost.

πŸ’‘

The ADB method is suitable for blocking pre-installed applications (such as Mi Video or Mi Music) that cannot be removed by standard methods.

6 Restriction of access through β€œParental Control”

  • πŸ•’ Setting time limits for using applications.
  • πŸ”ž Block access to 18+ browser-based.
  • πŸ“± Prohibit installation of new applications without password.

How to set up:

  1. Go to Settings β†’ Apps β†’ Parental Controls.
  2. Create. PIN-code (it must be different from the screen lock password).
  3. Select your child’s profile and set the limits for each application.
  4. Activate the option to Stop shopping to avoid accidental spending in the Play Market.

⚠️ Attention: Parental control in MIUI It doesn't block access to your phone's settings. If your child knows how to reset, they can get around the restrictions.

FAQ: Frequent questions about app blocking on Redmi Note 8 Pro

Can I block system applications (such as Settings or Phone)?
No, system applications (Settings, Phone, Messages) cannot be blocked through App Lock or third-party programs. This is a security limitation for Android, but they can be hidden through Second Space or disabled (unless they are critical to the system's operation).
Why did the MIUI update drop the application lock?
This is a known MIUI problem. After major updates (like version 12 to version 13), some settings are reset, including App Lock. To avoid this: Before upgrading, back up your settings in Settings β†’ About Phone β†’ Backup. After upgrading, don’t delete old app data (Cache and App Lock Storage).
How to block access to the Gallery, but leave access to the camera?
There is no separate lock for Gallery and Camera in MIUI, but you can use a workaround: Install a third-party gallery (like Google Photos). Block the standard Gallery via App Lock. Use Google Photos as your primary photo viewing app. The camera will remain accessible, as it does not depend on the Gallery lock.
Does app lock work if the phone is unlocked?
Yes, locking through App Lock or third-party programs works even if the phone screen is unlocked, for example, if you give the phone to a friend and he tries to open the blocked application, the system will ask for an additional password, but if you use Second Space, the profile that was active last will be opened when you unlock the phone.
Can I block access to mobile data for a particular application?
Yes, this is done not through app lockdown but through traffic restriction: Go to Settings β†’ SIM-maps and mobile networks β†’ Data transfer. Select Traffic Limitation for applications. Find the right application and turn off the mobile data for it.
