The cover is used as a backplane replacement. The rear wall is removed and the phone is inserted into the shell. At the edges is the cover on so that the mobile phone is also protected at the edges and corners. Through sensors in the rear wall of the cover, the phone will automatically recognize the new shell and changes the display. When cover is closed, you can select different displays. For calls an assumption without opening the cover is possible. Even photographs or playing music can be made without opening the cover. When you open the cover, the known and set image / background effect. By a magnetic closure, the cover does not accidentally open in your handbag. To operate the mobile phone, the front of the cover are folded backwards without taking damage. The material is high quality and I find the price reasonable. I use the cover for several months now and it still looks like new.
