Having to deal with people who snoop on your phone is an annoying experience. Hence, it's high time to download Pandora, an app to hide your photos and videos from prying eyes. You can lock these files with a password, keeping them protected. 

Thankfully, the app does not have a limit on the number of files you can hide so feel free to put everything under lock and key.  Even if you uninstall Pandora, all hidden media files will not be lost; however, you'll need to set your files from private to public. The app is available for free on the Play Store — no need to pay a fee.
