I personally don't understand how people expect to use these in the water with touchscreens. Seems difficult.
Glad you got good pictures. Mine were terrible.
I get really great video footage, and pictures... I usually start the video above the water and then go under... As for pictures, you can just use the volume button.
Also, it's amazing just being able to carry my phone in my pocket while i am in the pool or ocean, instead of leaving it behind...
