I own this envelope now about 1 year, so I can deliver a detailed report. You can really say that the Galaxy S4 fits perfectly into the shell. Audio and power connection are not covered. The micro and the switch can also be reached without problems, even in shell closed. The shell includes clean and tight. Even after one year (the "Zuklapplasche" a little 'worn' is) remains the shell closed. One gets the phone quickly in and out of the shell. The leather has a good grip, which does not mean that it has a non-slip surface. The stand-up function works even after a year still good. Was also often useful when watching videos look (YouTube) or films. The slit in the inside of the casing extends unfortunately neither for money, nor for a card. Another small flaw, the sutures (the threads) dissolve quickly. After a while a lot of the seams unfortunately have been merged. Through a little superglue that is also no problem.
Positives: + Perfect fit + Keeps your phone safe + Nice finish / rough + Good protection for the phone (only a small Macke after a year, because cell phone with an open envelope - from 1.5m - fell to the ground) + Ports and buttons remain free
Negatives: - Slot can not be used in the inside - Seams go quickly (by superglue no problem)
If you do not have too high demands on an envelope for 6 and who is not too good to stick a little if the seam should go up, for this shell is just the ticket, provided one has a S4.
