My Sony Xperia Z Ultra is equipped with a Rocina case; yet provided with an opening for the magnetic contact area. When I put it in the dock, the contact is not made with any of the 2 adapters. The only solution to that contact is made is that I remove the phone from its case, enough binding operation. Moreover it is necessary that the station is plugged in and not to a USB port. And so, icing on the cake but then I had misread the description, no data transfer with a PC via the station.
