when operating the side buttons. That would be the arrival & Button, down / up or zoom and the camera key. This case has at this point namely no holes like other cases. So you have on the silicone rumdrücken- if it were only one key, you could see over it, but since you are dealing with important keys, I come with this case, unfortunately, can not cope.
Otherwise, it really fits perfectly, is nice, delivery was fast, sits well ... But since I preferiere then yet another case and can not follow the other reviews.
For Xperia P so do not buy recommendation on my part.
