Now have already tested several vendors. Especially with larger smartphones (eg Xperia M2) is a slim case is noticeable - This fits here like a glove, is noble in design plus robust. Mini-USB and headphone jack, and all buttons remain easily accessible without having to take the phone out of the case. The magnetic lock facilitates rapid opening of the bag. Simply fold to call the front backwards and also turning the lock to the rear - also applies here to the magnetic lock and the phone is very comfortable. Even at the level of functional magnetic closure can be folded back to the rear facade and thus secured. The two credit card slots are ok, but should not be used by cards with magnetic strips, because the magnetic stripe might suffer by phone and by the magnet of the shutter. Best to own business cards, paper money, etc. so that the bag is not unnecessarily thick. All in one: A very well-designed bag for very little money - just buy it!
