How durable is Sony’s new flagship? The Sony Xperia XZ. Released in late 2016 this water resistant phone is going to end up in the pockets of a lot of people. Mostly outside of the USA. I put this phone through a series of tests. Scratch tests to see how easy the screen will scratch. And then I gently abuse the rest of the phone to see what it is made of. Is it a solid metal body like most flagships? or is there plastic incorporated into the design? My tests expose everything.
