Design and externals:
When the envelope I arrived very pleasantly surprised. The shell acts as a high-quality in the pictures. The shell is made of plastic and looks quite chic. In the pictures, however, the material looks a bit like a silicone type material from or to a material which does not look to hard plastic or the like. It is really good in the hand.
Functionality:
My S4 (GT-I9505) fits perfectly into the rear shell of the shell. It sits firmly without wobbling bombs.
The recessions that the battery cover will not close properly, or I can not share that the phone does not lock properly, with me everything is super! The S-viwe window is provided with a "protective plastic", so the window viewing at this point is additionally protected.
S-View works!
