Where is Dual Camera mode for Galaxy S5 Neo

[AC Question]

WHen I open up the MODE on the Samsung camera app there is no Dual camera mode that would allow me to use the front and back cameras at the same time. It gives a small postage stamp on the back camera and whole scene on front camera.
The old scrolling MODE interface has disappeared and has been replaced with something with less options. Is it possible to install the older camera interface with the dual camera MODE?
