Just bought the S View Cover a few days back. It was amazing with the small screen because I can answer phone calls and check the time without wasting so much battery power. It can also auto unlock and auto lock just by opening and closing respectively. The only disadvantage is that it only protects the screen and not the sides of the phone. The cover is also very expensive (SGD 78) especially for a student like me who is only in secondary school (or high school).
Overall, I would say that it is a very innovative and cool cover. However, if you are looking for a case that protects your phone, the S View Cover is not for you especially with that heavy price tag it carries.
