I have the envelope now used a month and am still not 100% happy with it. But let's start from the beginning: It is the back of the smartphone from to install it. The whole thing was very simple and straightforward. But what I find quite inconvenient is that the casing is very rigid and the flap is always easy, especially if you had just used the phone, then it takes a while to get draws on the door again. The advantage of this bookcases is that you can operate the phone and through the viewing window that is located in the cover, at least the most basic functions, such as answering a call and see if you were called or received a text message. Basically, a good idea, but unfortunately it works answer or end, calls, not so good, the wiping is not always recognized, I would say in 75% of cases are that's me clearly not enough. Even the stylus (S Pen) is difficult to pull out of the phone when the envelope was attached. Even me long fingernails. In my view, can be found here therefore better protection.
