Note: I was inside the house with no one around. I had my hands full and, just out of curiosity, I attempted to tap the Activity on the lower right corner with my (hairy)chin. On my first "headbutt", the watch opened up face customizations, but the 2nd try I hit the bullseye, and activity opened up! Maybe a future update can include a "headbang ring?! And hopefully, I don't stir up a new anti-social trend!! Has anyone tried to operate their watch with something other than your hand?
