i have the same problem, bought online. While i am contacting the seller, who claimed its 100% official case (Though i am not sure whats the behavior of the original case or whether the one i am holding is fake or faulty), at least i find a workaround without removing the case and reinstalling it while the device is running. i.e.,
Method 1: S-view recovery
i) Shutdown the device
ii) Start the device with the s-view cover open/closed.
This detects the s-view and bring up the s-view.
Method 2: Restart-working (s-view working)
i) After you push the 'restart' option, close the lid, you will see samsung logo on s-view
ii) Keep the lid closed, you will again see the samsung logo aon s-view window, so it works.
Method 3: Restart (s-view not working)
However if you keep i) the lid closed while shutdown & keep the lid open while booting, it doesn't work. You can recover by following method 1 (OR) Method 4
Method 4: S-view recovery
Another funny behavior is, even if s-view doesn't work, press the power-button while the lid is closed, the power menu options come up in s-view window, then, either i follow Method 2 or Method 3, s-view worked.
If you happened to re-produce, please post me, perhaps, either it is faulty case or seller magic
