I see no complains about magnets on the back activating sleep function on rev2. But it seems some complains about position of the front cover when it's closed that it depends of the position of the cover.If it's not properly closed it may not put it to sleep. Seems like yours doesn't have this problem,right?
Thanks
Make sure your iPad is all the way in the case, and and that the leather is flattened correctly. The magnets work perfectly here, and for many other people, no doubt. If they don't, exchange the case. My review samples have been flawless, as I mentioned in the review and on these boards, so you should expect nothing less than the experience I've encountered!
