On paper, the Sony Xperia XZ2 Premium represents a significant upgrade over the plain ol' XZ. The former delivers the contrast data; the latter the color data: the details from both are combined with Sony's AUBE fusion image signal processor. The dual lens system will also enable the popular bokeh effect for photos shot with Sony's camera, however, it will be made available sometime after launch in Q3 this year. That, Sony promises, is the sort of sensitivity that until now you'd have required an interchangeable-lens camera for, rather than being included in a regular-sized Android phone. In the camera department, there is a dual camera setup on the rear featuring 19MP RGB sensor with f/1.8 aperture and 12MP Monochrome sensor with f/1.6 aperture.
On the front, there is a 13MP camera with f/2.0 aperture which is a big step up from 5MP front camera of the XZ2.
The Premium model also has a 5.8-inch 4K HDR screen, while the regular XZ2 only boasts 5.7-inch Full HD+ HDR panel. It's a weird situation, seeing as how Sony nearly always releases its new phones in the United Kingdom, but it doesn't discount the option of buying an imported model. It uses Sony's X-Reality upscaling technology, too, capable of turning non-HDR footage into HDR. Under the hood, the smartphone is powered by a Qualcomm Snapdragon 845 processor, coupled with 6GB of RAM. For a more immersive video playback, it also gets S-Force surround sound and a Dynamic Vibration System that vibrates like Sony PlayStation's "DualShock" controllers.
It is also worth pointing out that the Xperia XZ2 Premium is quite heavy at 236 grams.
Also like the XZ2 is the design. Both the front and rear are covered in Gorilla Glass 5 with curved edges, and IP65/68 water resistance is present as well.
First there was the Samsung Galaxy S9 and then there was the Huawei P20 Pro. The Xperia XZ2 Premium has a Motion Eye dual rear camera setup with one 19-megapixel camera with a 1/2.3-inch Exmor RS sensor, 1.22-micron pixels, and an f/1.8 aperture, as well as one 12-megapixel black and white camera with the same Exmor RS sensor, 1.55-micron pixels, and an f/1.6 aperture. This should roughly translate into some good photos even at ultra-low light conditions. It had the honor of being named as the "Best New Smartphone at MWC 2017".
The Sony Xperia XZ2 Premium is set to go on sale this summer in other parts of the world, so if you're desperate to get your hands on the Xperia XZ2 Premium you'll have to look into potential imports in a couple of months' time. It'll be available globally, but pricing - and any carrier support in the USA - will be confirmed closer to release.
