This should be kept in mind before buying ...

So far absolutely okay, if, indeed if not for the But would:

I again bought about 6 weeks after buying another cover, because I'm not coped with the disadvantages.

1. The writing and the operation are annoying as the lid when writing is always in the way.
2. one flap while writing the cover back, because you want to minimize the problem to 1, the S4 detects a closed cover and the display switches to or if set equal to the locked state, the annoying.
3. It should be noted that even with universal brackets for vehicle etc. the lid is always in the way, for the exclusive telephone calls safely assume no problem, because the lid can be closed, but who wants to have Navi, Phonebook, or another app running all the time because the display must be visible, and that's not the point.

If the dear reader see none of the three applications above problems for themselves, then I can only recommend buying!
