You can see at a glance that the XZ Premium is a top-of-the-range phone. Sony calls the design ‘Loop Surface’, which means that the phone is made of a single, seamless glass plate with two rounded edges. The glass motif is even stronger at the back, which is reflective. In any case, it is a very unusual and original design that we haven’t yet seen in many other telephones. It looks lovely, but we do wonder how the reflective back deals with greasy fingers, because it seems to us to be a real magnet for fingerprints.
The screen is just under 5.5 inches, but unlike other top phones launched recently, it does not cover the whole of the front of the device. There is still plenty of room at the top and bottom for the front camera, loudspeaker and home button with built-in fingerprint reader. All in all, however, this device is fairly compact and sits very easily in the hand. Another positive point: the XZ Premium is water- and dustproof.
