Sony’s Xperia XZ Premium shines, quite literally. The first thing you notice about the new phone is the mirror-finish that surrounds the device giving it a sparkly appearance that seems destined to require lots of polishing.
But the innovation in the phone is found below the surface. Its primary features are both firsts on a smartphone: a 4K HDR display and super slow-motion video.
The 4K screen is 5.5-inches across, which means it’s small enough that the 4K resolution shouldn’t make too much of a difference. On a large screen like a television, the extra resolution is immediately noticeable but on a small screen it’s much more difficult for the human eye to discern.
