The Icelandic commercial is announcing that the Samsung Galaxy S4 supports the natives' language (which I guess the iPhone does not?).
The setting appears to be the remains of an ancient church.
Our hero first tries to manipulate an "apple" like it was a smartphone — with no luck. This is how you mock a competitor and avoid a C&D letter. Note the many "apples" laying on the ground.
But then, an S4 magically appears in his hands, and the creepy ninja-goat dance of happiness begins — at the end of which, I'm guessing, the poor goat was summarily sacrificed to the Tech Gods and our hero and the ninjas drank its blood.
That's my interpretation.
