The issue of personal data confidentiality is becoming increasingly relevant for mobile device users. Many smartphone owners are looking for ways to limit access to certain information, whether it's personal photos, financial apps, or just a call log. The developers of the Android operating system have provided various tools for these purposes, but their names and activation methods may differ depending on the version of the system and the manufacturer's shell. Users often confuse the concepts, calling “hidden mode” everything from private browsing of web pages to full encryption of folders.
In this article we will analyze in detail how to enable hidden mode on various models of smartphones. We will look at the standard capabilities of the system, functions of manufacturers like Samsung and Xiaomi, as well as third-party solutions. It is important to understand that there is no universal “Hide All” button, so you need to select a method for a specific task. Some functions require the installation of additional applications, others are already built into the settings menu.
Normal incognito mode in the browser and system
The most basic level of privacy is hiding your browsing history and search queries. In the Google ecosystem, this is implemented through incognito mode. It does not save browsing data, cookies, or information entered into forms after you close the tab. However, this mode does not encrypt traffic and does not hide your activity from your Internet service provider or network administrator.
To activate this feature in the browser Chrome, you need to click on the icon with three dots in the upper right corner of the screen. Select "New incognito tab" from the drop-down menu. The browser interface will change to a dark color scheme, signaling that you are in Protected Mode. Similar functionality is present in most third-party browsers, such as Firefox or Opera.
In addition to the browser, the latest versions of Android (starting with the 12th and especially the 14th version) have introduced a system limited profile mode. It allows you to create a separate space for children or guests, where access to your personal applications will be blocked. This is an effective way to hide content from prying eyes without deleting apps from your device.
Use the Ctrl+Shift+N key combination on a connected keyboard to instantly open an incognito tab in Chrome.
Hide apps through shell settings
Smartphone manufacturers often add their own add-ons on top of pure Android, providing advanced features privacy. For example, in devices Samsung with the One UI shell there is a “Hide applications” function. It allows you to remove the icons of selected apps from the main screen and from the menu, making them invisible to the average user.
To activate this function on Samsung, you need to go to Settings → Home screen. In the list of options that opens, find the "Hide applications" item. By clicking on it, you will see a list of all installed apps. Select the ones you want to hide and confirm the action with the "Done" button. Now these applications can only be found through a global search or in the settings, but their icons will disappear from the launcher.
In smartphones Xiaomi (MIUI or HyperOS shell) a more advanced mechanism is implemented - “Hidden Applications” with password access. This feature does not simply remove the icon, but requires entering a special code or fingerprint to enter. To enable it, go to Settings → Applications → Hidden applications and activate the switch next to the desired apps.
- 🔒 Access by fingerprint: entering hidden applications is possible only after biometric authorization.
- 👁️ Icon masking: some skins allow you to change the appearance of the shortcut to a neutral one.
- 📂 Trap folders: creating fake folders that open without a password, but do not contain important data.
- 🔍 Search by code: entering a special code in the dialer to open a hidden section.
What to do if there is no “Hide applications” option?
If there is no such option in the standard settings of your smartphone, this means that the manufacturer has not implemented it into the shell. In this case, it is recommended to use third-party launchers (for example, Nova Launcher) or safe applications that create a protected environment within themselves.
Using Secure Folder and Safe Folder
One of the most reliable ways to hide files, photos and applications is to use an isolated space, often called "Secure Folder" or "Private Space". Unlike simply hiding icons, this method creates an encrypted container inside the device's memory. Data placed there is inaccessible to other applications and is not displayed in the gallery or file manager without authorization.
On devices Samsung this function is called Secure Folder (Secure Folder). It uses the Knox platform to protect data at the hardware level. To add an application to Secure Folder, you need to open the application folder itself, click the "Add applications" button and select apps from the main list. A complete copy of them is created inside the folder, which works independently of the main system.
In smartphones Xiaomi and Redmi the “Second Space” function is an analogue. This is actually the creation of a second user profile with its own set of applications, passwords and files. Switching between the main and second space occurs instantly using a fingerprint or a special password. To activate, go to Settings → Second space → Enable.
☑️ Setting up a secure folder
This allows you to have two copies of the same messenger with different accounts, one of which will be completely hidden from prying eyes. The data inside such a container is encrypted with a key that is stored in a protected area of the processor.
⚠️ Attention: When resetting your smartphone to factory settings, data in protected folders and second spaces may be lost forever if you have not created a backup copy separately for this profile.
Hide contacts and call history
Often users need to hide not applications, but specific contacts or call history. The standard "Phone" application in pure Android does not always have a built-in function for hiding contacts, but many manufacturers add it. Xiaomi has a "Hidden Contacts" feature, accessible through the "Contacts" or "Security" application. MIUI Xiaomi has a "Hidden Contacts" feature, accessible through the "Contacts" or "Security" application.
To hide a number in MIUI, open the "Contacts" application, go to settings and select "Hidden Contacts". You will be prompted to set a security password. After activation, hidden numbers will not be displayed in the general list. To call such a contact or see it, you need to enter a special code in the dialer, for example, #1234# (the code is set to custom during setup).
On devices Samsung there is no direct function for hiding contacts in the standard application, but you can use a workaround through export and import. You can export the desired contacts to a VCF file, delete them from your phone, and save the file in the "Secure Folder". If necessary, the file is imported back. There are also third-party contact safe applications that replace the call list with an empty one or a random one when you enter the wrong password.
| Function | Samsung (One UI) | Xiaomi (MIUI/HyperOS) | Pure Android |
|---|---|---|---|
| Hide applications | Yes (in screen settings) | Yes (with password) | No (launcher needed) |
| Secure folder | Secure Folder (Knox) | Second space | Personal folder (Android 15) |
| Hide contacts | Through export/import | Built-in function | Third-party applications |
| Hide notifications | Notification settings | Notifications (Lock) | Access restriction |
Using Second Space or Secure Folder is the most reliable way to separate personal and work information on one device without the risk of leakage.
Restricted Access Mode and Guest Mode
If you need to temporarily transfer the phone to another person, but you do not want him to see your personal data, Guest modewill be the ideal solution. This feature creates a temporary user profile that does not have access to your photos, contacts, or installed applications. The guest can only use basic functions and those apps that you allow.
To enable guest mode, lower the notification shade twice to reveal all quick settings tiles. Find the icon with a silhouette of a person (usually in the corner of the screen) and click on it. Select "Guest". The system will switch to a clean profile. To exit the mode, click on the user icon again and select your main profile, confirming the action with a password or fingerprint.
In Android 15, Google has introduced the function Private Space (Personal Space) as a standard element of the system. This is a native implementation of Secure Folder, available on all certified devices. It allows you to install applications that will be visible and accessible only within this space, hidden behind a separate lock screen.
- 👤 Data isolation: applications in guest mode do not have access to the data of the main user.
- 🚫 No history: after leaving guest mode, all downloaded files and browsing history are deleted.
- 📞 Calls and SMS: the guest can make calls, but they are not saved in the main profile log.
- ⚙️ Settings: changes in the system settings made by the guest do not affect the main profile.
⚠️ Attention: The user switching interface may differ on different models. On some devices, this function may be disabled by default in the menu
Settings → System → Multiple users.
Third-party solutions and safe applications
If the standard capabilities of your smartphone do not satisfy your privacy needs, you can always turn to third-party software. There are many applications that specialize in creating secure storage. They work on the “safe” principle: you install one shell application, and inside it store photos, videos and documents under a secure password.
Popular solutions include Gallery Vault, KeepSafe i AppLock. These apps often have additional features, such as taking a photo of the attacker if the password is entered incorrectly or the ability to open an application under the guise of a calculator. However, using third-party software carries certain risks: data is stored in encrypted form within the application, and if it is deleted or fails, access to files may be lost.
When choosing such software, pay attention to the permissions it requests. A good safe app shouldn't require access to your contacts or microphone without a good reason. It is also recommended to regularly back up the contents of the safe to cloud storage, if the developer provides such an option.
Before installing a third-party safe, check reviews about the possibility of data recovery if your password is forgotten. Some applications do not have a reset function, which will lead to loss of information.
Frequently asked questions (FAQ)
Is it possible to hide applications on pure Android without root access?
Yes, this can be done using third-party launchers, for example, Nova Launcher or Microsoft Launcher. In their settings there is a section “Hide applications”, which removes icons from the menu. Also in Android 15, a native Private Space feature has appeared.
Will notifications be received from hidden applications?
If the application is simply hidden from the menu (the icon has been removed), notifications will arrive as usual. If the application is placed in a Secure Folder or Second Space, notifications will only be visible when you are inside this secure profile.
What happens if I forget the password for the hidden folder?
In most cases (Samsung Knox, MIUI), during setup it is suggested to link your Samsung or Mi Account to reset the password. If the account has not been linked, it is almost impossible to restore access to the data inside the protected container due to hardware encryption.
Does incognito mode hide my IP address?
No, incognito mode in the browser hides the history only on the device itself. Your ISP and the sites you visit still see your IP address and location. To hide your IP, you need to use VPN services.
How to hide a phone number when calling?
To hide a number one-time, use the code #31# before dialing the subscriber's number. To hide the number for all outgoing calls permanently, go to the Phone application → Settings → Additional settings → Caller ID and select “Hide number.”
