Samsung has two commercials airing currently with new forms of interaction ... might be the Galaxy S3 (I'm not sure). One example shows the user dismissing a call by speaking to the phone while a call is coming in. The other commercial shows that you can take a screen-shot by waving your hand over the device whenever - kind of ironic since screenshots from Android devices was always a pain back when I owned one.

Maybe they both work flawlessly - I don't know, but both seem like they could easily misfire when you intended to do something completely different with your device.

I have an S3, and the screenshot thing is actually very neat and handy. It is a bit wonky when you try to capture apps with scrollable windows, but it never misfires. You have to basically press the side of your palm on the screen and move it from left to right.
