Query: Doesn't work for me.

This type of case didn't work for me. The side covering the qwerty keyboard would slip around a lot and even come off. It also doesn't allow for the phone to close completely causing the phone to flop open unexpectedly. Got agravated with it so I took it off and put it in the drawer. Next step will probably be to put it in the circular file. I'm using a holster type case now that came with my laptop bag.
