Small cable magic, I even tested my webcam (careful not need rooter your device, there are applications that work) Keyboard ok. I found something nice. Before having my tablet I had a 4G Galaxy S3 with a small camera to see the screen on a TV via HDMI. You will notice that the new Samsung UBS3 port is actually two small ports rating rating. The larger of the two is the same as the 3S. And it works there is only the sound that always passes through the tablet.
