Smartphone owners Samsung Galaxy A50 often face the need to hide personal correspondence, photographs or bank data from prying eyes. A standard screen lock, although the first line of defense, does not protect the contents of running apps if the phone is already unlocked. Fortunately, the shell One UIinstalled on devices of the South Korean giant provides powerful built-in tools for solving this task without the need to obtain root access.
The most effective and safe way to protect content on Samsung A50 is to use the function Secure Folder (Protected folder). This sandbox operates as a “smartphone within a smartphone,” where each app has its own copy of the data and requires separate authentication to log in. Unlike simple blockers, this system encrypts data at the hardware level using the platform Samsung Knox.
However, not all users want to move applications to a separate folder. Some people prefer to leave icons on the desktop, but limit access to them. For such scenarios, there are alternative methods, including third-party launchers and specialized utilities from Google Play. The choice of a specific method depends on how deeply you want to integrate protection into the system and whether you are willing to put up with possible functionality limitations.
Using the built-in Secure Folder
Function Secure Folder is the flagship security solution in the ecosystem Samsung. It creates an encrypted container that can only be accessed after entering a PIN, pattern, or fingerprint other than the primary one. To activate this mode on Samsung A50, you need to go to menu Settings → Biometrics and security → Secure folder.
After turning on, the system will prompt you to log in to your account. Samsung Account. This is a mandatory requirement, since the data is encrypted and linked to your account. If you forget your Secure Folder password, you can only restore access through your Samsung account, so make sure your login information is up to date. The setup process is intuitive and takes no more than a couple of minutes.
Inside the created folder you will find an empty desktop. To protect a specific application, for example WhatsApp or Telegram, click the “Add applications” button and select the desired apps from the list of installed ones. It is important to understand that a copy of the application is added to the folder. This means that you will have two Instagram: one regular and one protected, with independent settings and accounts.
⚠️ Attention: When you delete an application from the Protected Folder, all data inside it (correspondence, photos, cache) will be permanently deleted. Make sure you back up important information before emptying the container.
Use different fingerprints for the main screen and Secure Folder. This will allow you to instantly open the desired profile simply by placing a specific finger on the scanner.
For maximum convenience, it is recommended to configure the display settings. You can hide the Secure Folder icon from the main screen, leaving access to it only through the notification panel or settings. This makes the fact of the presence of secret applications on the device less obvious to prying eyes.
Setting up blocking through third-party applications
If using a separate folder seems inconvenient to you, applications from the store Google Playsuch as AppLock or Norton App Lock. These utilities layer a layer of security on top of regular icons, asking for a password every time you launch the selected app. Installing such software does not require complex manipulations with system files.
After installation and initial setup, the wizard will prompt you to select the applications that need to be protected. The mechanism of operation is simple: when you click on the icon of a blocked application, the system intercepts the launch and displays a password entry screen. Only after successful authentication does the target app open in normal mode.
However, it is worth taking into account the peculiarities of the operation of such apps on modern versions. Android. The system strives to save battery power and can forcefully close background blocker processes. To avoid situations where protection suddenly turns off, you need to pin the application in memory and turn off power consumption optimization for it.
☑️ Setting up AppLock
Some advanced blockers offer the “False Password” function. If you enter a special code, a set of “safe” applications that do not contain confidential information will open. This is a useful mechanism if you are forced to unlock your phone under pressure.
Comparison of data protection methods
Choosing between built-in tools Samsung and third-party solutions often causes confusion for users. Each method has its own advantages and disadvantages, which directly affect ease of use and level of security. Below is a table to help you decide on the best option for your needs.
| Criteria | Secure Folder (Built-in) | Third-party AppLock | Blocking via Settings |
|---|---|---|---|
| Encryption level | Hardware (Knox) | Software | None |
| Impact on battery | Minimal | Medium/High | Absent |
| Bypass complexity | Very high | Average | Low |
| Work in the background | Stable | Requires configuration | Not applicable |
As can be seen from the comparison, Secure Folder is the undisputed leader in security. It is integrated into the system core and uses a dedicated, secure processor. Third-party applications, although convenient for quickly blocking individual icons, are vulnerable to more experienced users who can complete the blocker process through the menu of running applications.
To store banking applications and personal photos, definitely select the Secure Folder. Third-party blockers are suitable for temporarily limiting children's access to games.
It is also worth noting that some third-party software manufacturers may collect usage statistics. In the case of a proprietary solution from Samsung data is processed locally on the device in encrypted form, which guarantees confidentiality.
Setting up biometric protection
Entering a password every time you open the application can become tedious. Samsung A50 equipped with an optical fingerprint scanner fingers located under the screen, and a facial recognition system. These tools can be effectively linked with application locking functions for faster access.
In Settings Secure Folder you can activate the “Use fingerprint” option. After this, entering the secure container will be carried out with one touch. Many third-party lockers are configured in a similar way, although their work with biometrics is sometimes less stable due to API restrictions Android.
In some jurisdictions, you may be required to unlock the device with a fingerprint at the request of law enforcement agencies, while the password (knowledge) is more protected by law. Additionally, the scanner may not work if your fingers are wet or dirty.
- 👆 Set up multiple fingerprints for different use cases.
- 🔐 Always have a backup PIN in case your biometrics fail.
- 👁️ Use facial recognition only when paired with other protection methods.
To increase security, it is recommended to periodically change the pattern or PIN code, especially if you suspect that someone might have spied it when unlocking your phone in a public place.
Hide applications without setting a password
Sometimes the task is not to block it, but to The application icon was not an eyesore at all and was not visible in the menu. Shell One UI allows you to hide applications directly from the desktop settings. This does not protect the data with a password, but removes the visual trace of the presence of the app.
To use this function, long-tap on an empty space on the desktop and select Settings. Next, find the section Hide applications. Here you can tick the apps that you want to remove from the general list. They will disappear from the application menu, but will remain installed on the system.
How to find hidden applications?
To return hidden applications or launch them, you need to go back to the desktop settings, select “Hide applications” and click on the icon magnifying glass or simply enter the name of the app in the search, if this function is supported by your version of the launcher.
This method is often combined with Protected Folder: the main application is hidden, and its protected copy is placed in Secure Folder. This achieves a double level of privacy: no one sees the icon, and access to data requires separate authentication.
Remember that hiding icons is not a security measure. Anyone who knows how to use Settings Search or has access to the Application Manager will be able to find and launch the hidden app. Use this method only for aesthetic purposes or as an addition to a password.
Possible problems and solutions
In the process of setting up protection, users Samsung A50 may encounter a number of typical problems. For example, notifications from apps in Secure Folder may not arrive if background activity is limited. This can be solved by issuing permission to work in the background in the battery settings.
Another common problem is the inability to add an application to Secure Folder. This usually concerns system utilities or apps that the developer has prohibited from cloning. In such cases, the only option is to use third-party blockers, although they are less reliable.
⚠️ Attention: The interface and menu names may vary slightly depending on the Android version and One UI update. If you do not find the item in the specified location, use the search in the settings.
If a blocked application starts to work incorrectly (crashes or freezes), try clearing its cache inside the Protected Folder. Often, a data conflict between the main and protected versions of one app causes malfunctions.
In rare cases, after updating the system, security settings may be reset. It is recommended to check the status Samsung Knox in the security settings after each major firmware update to ensure that the protection is active and has not been compromised.
Frequently asked questions (FAQ)
