I am by the S4 with the foldable shell spoiled a view "window" to the mobile phone to have. LG goes one step further and lets the "glass" away. Thus you can create a circular opening through the keys and other objects nice scratch the display. Also I had suddenly up to 100 black and gray images on my card, the camera can thus be run by and sitting by the window activate. Even the music suddenly starts running, because the phone thinks it would be my thigh for music ... You can not limit the functions of the window but just completely disable the phone but not even this responds to opening the envelope. I'm going to buy the envelope without window because I'm really unhappy with the function.
