Many Android devices offer a built-in feature called “Secure Folder” or similar, which allows you to hide and secure photos, videos, and other files behind an additional layer of protection. Here’s how you can use Secure Folder on Samsung devices as an example:

Setting Up and Using Secure Folder:

1. Open Secure Folder:

   • Go to your device’s app drawer and find the Secure Folder app.
   • If you can’t find it, go to Settings > Biometrics and security > Secure Folder to set it up.

2. Sign In or Create Secure Folder:

   • If you’re using Secure Folder for the first time, you’ll need to sign in to your Samsung account or create one.
   • Follow the on-screen instructions to set up Secure Folder.

3. Add Content to Secure Folder:

   • Once Secure Folder is set up, open the app.
   • Tap on “Add files” or “Add content” to select the photos and videos you want to hide.
   • You can also move existing files to Secure Folder by selecting them and choosing “Move to Secure Folder” or a similar option.

4. Access Secure Folder:

   • To access your hidden photos and videos, open the Secure Folder app and enter your PIN, password, pattern, or use biometric authentication (e.g., fingerprint, face recognition).

5. Manage Content in Secure Folder:

   • You can organize, view, and manage your hidden files within Secure Folder just like you would in any other folder on your device.
   • Additionally, you can add apps to Secure Folder to keep them separate and secure from your main apps.

Additional Tips:

• Backup: It’s a good idea to regularly back up the content in your Secure Folder, especially if you plan to reset or switch devices.
• Security: Ensure that you use a strong PIN, password, or pattern to protect your Secure Folder. Avoid using easily guessable combinations.
• Biometric Authentication: Using biometric authentication (fingerprint, face recognition) adds an extra layer of security and convenience.
• Emergency Access: Some Secure Folder implementations allow you to set up emergency access in case you forget your credentials. Take advantage of this feature if available.

If your device doesn’t have a built-in Secure Folder feature, you can explore third-party apps available on the Google Play Store that offer similar functionality, such as GalleryVault or Keepsafe. These apps typically provide options to hide and secure photos, videos, and other files behind a PIN, password, or fingerprint lock.
