The Newest Flagship from Sony is the Xperia XZ Premium, released in 2017 this is the successor to the normal Sony Xperia XZ… While the phones sound similar, they are actually very different in size and specs, so I’m really not sure why the names are correlated. Either way, this new devices is top of the line when it comes to Screen resolution and quality. The 4K pixels and HDR display makes the Xperia XZ one of the most powerful displays in the smart phone world. Pretty impressive.
