After a long search for the perfect cover my S2, some not to recharge the closed position or other with adhesive holding only a while, I finally found the perfect bag! So my Galaxy is properly seated (even with a larger battery and thus a greater thickness than the base!), I can use headphones and charge in the closed position (finally!), The valve can be opened and close easily with one hand, and the flap has a certain thickness which ensures good protection of the screen. See however in the long term for the holding of the valve but if for now it is perfect! I therefore strongly recommend this purchase ...
