I do not know what all have. With me everything is working fine. Mobile holds such bomb in cover, but all the functions go well. One point deduction, because if I had opened lägere time the cover, then close the cover is a little open when. However, it does not take long until it then gives way again, and closes. Collect as cover so far the best. Because it is only marginally so thick the phone and still fit nicely in your pocket. Ordered it with Prime. Within one day came the delivery. Because some write, they do not know where there is cover. Then you should stop and have a look where the dealer is. These are the people who want the best for very little money an original cover .. without words.
