Cheapest price i could find. Just received mine and confirm that it comes with retail packaging and is the Samsung official product. A recent update to the Samsung Always On Display app enables AOD in the S view window. Note: this case is for the S7 only NOT the S7 Edge.
UPDATE: Also available in silver colour CLICK HERE
The official blurb.....
Enjoy the latest features via the S View window
The Galaxy S7 S View Cover has a clear wide window on the front through which you can access features like music control, wallpaper editing, reject call, message transfer and quick camera. The case also benefits from other upgraded features such as quick call using the frequent contact list, quick camcorder, check your heart rate and torch light, to name but a few.
Fast Mode Switching for Camera and Camcorder
The S View Cover allows quick access to the Camera Mode and can be switched to Camcorder Mode directly from Camera Mode in one simple motion. Using the fast mode switching function you can be sure to capture those moments that you previously might have missed.
Edge Coating & Side Protection
The special edge coating on the S View covers provide the premium finish expected with a Samsung original accessory and gives you a better and more secure feeling of grip. The edges and corners of the cover also extend beyond the edge of the S7 to give that extra protection you sometimes need.
Automatic Screen On / Off
With the Galaxy S7 S View Cover, your screen will switch on / off automatically when opening and closing the cover.
