All of the pictures, and the so-called video testing, are bending the device OUTWARDS against the screen. I have NEVER seen anyone put an iPhone in a front or back pocket with the screen facing outward - that would be a recipe for sure fire disaster for the screen by hitting your leg against a desk, table, or other object.
Same goes for the bent iPad - just coincidence - I think not...
Your thigh can activate the camera if the screen faces inwards.
