At first I was skeptical about whether the bag was actually too narrow for the S4, as indicated by some Vorrezensenten. And in fact, they seemed at first to be very narrow-cut, so it needs some effort in order to squeeze into the leather sheath. However, in recent days have passed in which I have the phone back pushed consistently over and over again into the sheath (!! specified by the manufacturer) so that the leather has widened. It can be pushed now considerably lighter in the envelope and take out again. Also, the first somewhat yet been acting leather has now let soften slightly from the use, without it being lost a sense of value.
One star deduction for waste and pollution:
The leather case is supplied in a bonded plastic foil. Unless more comprehensible. The plastic film then infected but again in a plastic film (to protect the underlying plastic wrap ??) and to make matters worse is the leather case again surrounded by a glossy coated paper belt. The entire package of Galaxy S4 comes with less (plastic) from waste. This may in the 21st century. Just no more.
