Even though the screen resolution has changed, the Xperia XZ retains the same 5.2in display as previous models, and the familiar ultra-slim power button-cum-fingerprint sensor once again adorns the side of the handset. You’ll need to press the sensor before it can recognise your fingerprint, but on the whole, it’s pretty quick and accurate. Likewise, with built-in NFC on board, it’s primed and ready for Android Pay, so you can use it to make contactless payments. This phone is a pick from me.
