SPIGEN SGP Samsung Galaxy S4 Case Protective [Slim Armor] with S View Window / S View Cover Flip Cover Protection for Galaxy S IV Galaxy SIV i9500 (Wireless Phone Accessory)
When I unpacked the case, it made a very stable and high-quality impression. It's clean and processed accurately. The S4 detects the lid automatically and then goes into the special S View mode. Here you can then accept or reject calls by the window.
