What is Private Mode
Enabled on modern Samsung Galaxy devices (tested to work only on the Galaxy S5 and S6, your mileage may vary), this feature is available through TouchWiz exclusively, as of now. It basically allows you to hand over your phone to another user, and letting you have peace of mind, knowing that you critical data is out of their reach. This data includes things like your images, videos, voice recordings and other such files. This data can then only be seen once Private Mode is enabled. Keep in mind, however, that third-party apps can still access that data. Private mode also conveniently puts up a passcode protection that you must enter before entering.
