Did you ever wonder how to use both your front and back camera for taking pic-in-pic fotos or videos?
As far as I am concerned, Samsung offers its Dual Camera since the Galaxy S5.
How to get the Dual Camera?
The Dual Camera is an extension for the regular Samsung Camera App which comes w/ your phone. Open the camera App, navigate to ‘Mode’ and choose to download more features. The Samsung store offers some more features which you might already have missed. Alongside the Dual Camera you will also find a sports mode and a portrait mode.
