Android users are particularly concerned about privacy and data safety, especially when saving sensitive files, images, or papers. Whether you are concerned about someone peeking through your gallery or want to protect business-related content, Android has built-in security features that do not require third-party apps.
This guide describes how to use secure folders and app-based file protection features on several Android devices, including Samsung, Google Pixel, and more.
What is a secure folder
A secure folder is a safe location on your Android smartphone where you can keep programs, files, and media separate from the main user interface. Access requires authentication (PIN, pattern, or fingerprint), ensuring that only you can open it. When data is moved to a safe folder, it is rendered invisible in conventional folders and apps such as Google Photos or File Manager.
Samsung’s Secure Folder is the best-known example, however other manufacturers provide comparable functionality.
How to use Secure Folder on Samsung Galaxy devices
Samsung offers a native solution called Secure Folder, available on most devices running One UI:
- Enable Secure Folder:
- Go to Settings > Security and privacy > Secure Folder.
- Sign in to your Samsung account if prompted.
- Set your preferred lock method (PIN, password, or biometric).
- Add apps or files:
- Open the Secure Folder app from your app drawer.
- Tap Add apps to duplicate apps like Gallery, Notes, or Email.
- Tap Add files to move photos, videos, or documents from regular storage.
- Access and manage your folder:
- Secure Folder functions as a sandbox. Files here do not interact with the rest of your phone.
- Notifications from apps inside Secure Folder can be hidden.
- You can even hide the Secure Folder icon for additional privacy.
Samsung’s Secure Folder is protected by Samsung Knox, ensuring hardware-based encryption.
How to create secure folders on Google Pixel (and stock Android)
Google Pixel and stock Android phones don’t include a “Secure Folder” app like Samsung, but there are still options:
1. Use Files by Google – Safe Folder
Files by Google includes a Safe Folder to protect sensitive files.
- Open the Files by Google app.
- Tap Browse, then scroll to Collections > Safe folder.
- Set up a 4-digit PIN when prompted.
- Move any files (photos, documents, videos) into the Safe Folder for encryption and restricted access.
Limitations:
- No secure app duplication.
- Cannot protect entire apps—only individual files.
2. Use screen pinning or app lock (if supported)
On Pixel phones, you can use screen pinning to lock a specific app:
- Go to Settings > Security > Advanced > Screen pinning.
- Turn it on and set it to ask for unlock credentials.
When enabled, you can lock an app to the screen and prevent switching until your PIN or fingerprint is entered.
Secure folder alternatives for OnePlus, Xiaomi, Vivo, and Realme
Many Android OEMs offer their own version of secure folder functionality:
- OnePlus (App Lock & Hidden Space):
- Go to Settings > Utilities > App lock to lock apps.
- Use Hidden Space (swipe right in the app drawer) to hide apps or files from plain view.
- Xiaomi (Second Space or App Lock):
- Second Space lets you create a full-profile clone for private use.
- App Lock in Settings lets you password-protect apps and media.
- Vivo/Realme:
- Use File Safe or Private Safe under Security settings.
- This lets you encrypt and store sensitive files securely.
Each of these tools serves a similar purpose: creating a private area for your data and apps that only you can access.
When should you use a secure folder
Secure folders are ideal for:
- Storing sensitive photos, work files, or legal documents
- Keeping personal messages or notes private
- Isolating apps with private data
- Creating a private profile for shared phones or kids
If your phone is shared, stolen, or accessed without your knowledge, a protected folder provides an additional layer of security.
Android provides numerous options to protect your most sensitive data, with secure folders ranking among the best built-in solutions for the purpose. Whether you use Samsung’s powerful Secure Folder, Google’s Safe Folder, or manufacturer-specific features, these solutions offer true privacy without the need to install third-party apps. To protect your digital life, ensure that they are correctly configured and that you use a strong authentication technique.
