This is a stunt by Samsung and some Elephant named Peter from Thailand. Peter the elephant is caught on video pulling stunts on the Samsung Galaxy Note, and as you can see on video, he is actually enjoying music he is strumming off an app on the Galaxy Note. At some point he is even handed an S pen and actually draws. The video was inspired by videos of a frog and a lizard playing with a smartphone.
The video uploader wants us to believe its real, and goes ahead to provide links of the un-edited footage below. I would say its an awesome stunt for a viral video at the same time when Samsung announced the 5 million mark in Galaxy Note Sales.
