Thanks for this thread. I freaked when buying and trying a Poetic case that has the smart on/off feature -- it bypasses the lockscreen! WHAT? Now I know where to shut that off. I didn't even think the switch would be configured under accessories (looked everywhere else).
One thing to note (no pun intended) is that the Poetic case has the "hinge" on the bottom, so when the cover is "open" you can just let it hang down so it does not block the camera on the back. If the genuine Samsung case is designed the opposite, then that's a real boneheaded move by Samsung.
