Smartphones have become digital repositories of our personal lives, containing correspondence, banking data and sensitive photos. Xiaomi device owners often look for ways to restrict access to certain programs to protect privacy from prying eyes. The Redmi 7 Note, which uses the MIUI shell, offers built-in and powerful tools to solve this problem without installing third-party software.
Installing protection on specific applications is not just a whim, but a necessary security measure in an environment where children or colleagues can use the phone. Android system in conjunction with the manufacturer's proprietary add-on allows you to flexibly configure access parameters. In this article, we will discuss all the stages of configuration so you can be sure of the safety of your data.
Before you start making changes to the system, it's only a matter of minutes to get the configuration right, but the result will allow you to sleep better knowing that access to instant messengers or a gallery is securely closed. Let's look at the step-by-step algorithm for your model.
Built-in protection in MIUI
The MIUI shell on the Redmi 7 Note has its own security module called Application Protection, which works at a system level to ensure its stability and avoid conflicts with other programs, so you don't have to search and download dubious utilities from the Internet, risking infecting the device with viruses.
The built-in blocker allows you to set a separate password or use biometric unlock, which means that even if the phone is unlocked, access to selected programs will be blocked by an additional barrier, the system remembers your preferences and will not require a code at each start if you set the waiting timer.
⚠️ Note: When you first activate the function, the system will prompt you to create a special password for protection.
Native tools are also preferred because they are optimized to work with your smartphone’s processor and memory. Third-party devices often consume more battery life and can cause delays in the interface. The built-in mechanism works quickly and is almost invisible to the user in everyday scenarios.
Step-by-step instructions for activating the blocker
To get started, you need to go to the main settings menu of your device, find a section called "Applications" and select "Application Protection" there, and that's where all the tools you need to manage access to your software are concentrated.
Once you log in, the system will ask you to come up with a unique pattern lock or digital code that will be used solely to log into secure programs, and it is important to remember it or write it down securely, as restoring access without this code can be a difficult task.
Follow the algorithm further:
- 🔒 Enter the invented password twice to confirm its correctness.
- 📱 Link your Mi Account if the system offers to do so for backup recovery.
- ✅ Click the "Enable Application Protection" button to activate the module.
- ⚙️ Select from the list those programs that you need to restrict access to.
Once you do this, you'll see a lock icon next to the selected apps, and now when you try to open WhatsApp or Gallery, you'll ask for proof of identity, and you can change the list of protected programs at any time by going back to the same settings menu.
☑️ Checking the security settings
Set up biometric unlocking
Entering a password can be tedious every time, especially if you use secure apps a lot. Fortunately, the Redmi 7 Note features a fingerprint scanner that can be integrated with application protection, which greatly speeds up the access process and increases security.
To activate this feature, go to the security settings and find "Advanced" or "Unlock settings." There you need to activate the "Unlock fingerprint" switch. After that, the system will check your finger against the template stored in memory each time you access the blocked program.
The use of biometrics has its own characteristics:
- 👆 The scanner reacts instantly, which is more convenient than entering a pattern lock.
- 🛡️ The fingerprint is unique, which increases protection from strangers.
- 🔄 When restarting the smartphone, the first input will still require entering a password.
It is worth noting that some versions of the firmware also have facial unlock, but it is considered less safe than a fingerprint. For maximum reliability, it is recommended to use a fingerprint sensor located on the back of the case.
💡
Rub your fingerprint scanner regularly with a soft cloth – contaminants can reduce the speed and accuracy of recognition.
Fine settings and access parameters
The protection system on Xiaomi allows you not only to put a barrier, but also to flexibly adjust its behavior. In the Settings menu inside the protection section, you will find the option "Timeout", which determines how often the system will request a password after you have folded the application.
The following system behavior options are available:
- ⏱️"At once” – a password request appears every time you open.
- ⏳"1 minute" - convenient if you switch between programs frequently.
- 🔒"10 minutes: maximum comfort, but less security.
You can also turn on the Hide Content feature in this section, if this option is activated, then when an incoming call or message from a protected application is activated, the text of the message or the name of the interlocutor will not appear on the lock screen, this prevents information from leaking even when the phone is lying up.
⚠️ Note: If you forget the password from the application protection, you can reset it only through the Mi Account account to which the phone was attached when setting up.
Another useful feature is the ability to hide the application icons themselves. In some versions of MIUI, this is done through a separate Hidden Applications menu, but often these functions overlap. Hidden programs are not displayed in the shared list and are only accessible through a special gesture or code entry in the dialer.
Alternative methods of access restriction
If you're not comfortable with the built-in tools for some reason or you need a second space, there are other options to consider. Xiaomi has a Second Space mode that creates a completely isolated environment on your smartphone, like having two different phones in the same case.
To activate the second space, go to Settings → Second Space, where you create a separate desktop with your apps, contacts, and photos, and switch between the main and second spaces either through a notification curtain or a special fingerprint.
Comparison of protection methods:
| Parameter | Application protection | Second space | Guest mode |
|---|---|---|---|
| Level of isolation | Low (entrance only) | High (separate OS) | Medium (restricted access) |
| Difficulty setting up | Simple. | Medium | Simple. |
| Impact on the battery | Minimum | Notable. | Minimum |
| Better for you. | Personal photos and chats | Separation of work and rest | Temporary telephone transmission |
Guest mode, in turn, is suitable for situations where you give the phone to someone else for a short time, it does not allow the guest to see your contacts or make purchases in the app stores, but for constant personal protection, it is less convenient, because it requires changing profiles.
What to do if you forget the password from the second space?
Resolving problems and issues
During operation, users may encounter a situation where the protection stops working correctly, for example, the application opens without asking for a password, most often this is due to the fact that the system "killed" the blocking process to save energy. To avoid this, look in the application list "Application Protection" and in the battery settings select "No restrictions".
Another common problem is that you don't have to request a password after you update the system, in which case you should re-enter the security menu, turn off the function and turn it on again, and this will overwrite the configuration files and restore the functionality2 of the security module.
If you decide to completely abandon the use of protection:
- 🚫 Go to the menu "Application Protection".
- 🔓 Enter your current password or use a fingerprint.
- 🗑️ Click on the settings gear and select "Switch off application protection".
- ✅ Confirm the action, after which all the locks from the icons will disappear.
Remember that you cannot delete the Security or Security application itself, as it is a system component of MIUI. You can only disable its functions as described above. Regularly updating your security system through the Security app guarantees protection against new threats.
💡
For stable application protection, it is necessary to prevent the system from saving energy for this module in the battery settings.
