If you want to keep your pictures away from prying eyes on your Android device, there are three methods you can use. The first method involves downloading a file locker app from the Play Store, such as KeepSafe or Gallery Lock, among others. These apps will lock your pictures so that they can only be accessed with a password.

The second method is creating a hidden folder yourself, which involves renaming a folder with a period at the beginning of its name so that it becomes invisible. You can then move your pictures into that folder and they won’t be visible in your Gallery app.

The third method is creating an encrypted zip archive using a password of your choice. This method is more secure, as the pictures will be completely hidden until the archive is unlocked with the correct password.

Choose the method that works best for you to keep your pictures hidden and secure on your Android device.
