In the specific case of the Xperia Z3 this envelope works, however, the holder pushes exactly on the "Volume Up" button. When press firmly so pressing happy times on "loud", but the key is not always actively pressed. This thing is so useful, but would have been much better if the side jaws were much higher for the Xperia Z3. Therefore only 3 stars because there should be another product of the Z3 and this one should not be applied for the Z3, because it is not really suitable.
For me, this is now so fine, but again I would not buy the product with the knowledge.
