Sony's new phone has an AUBE Fusion image signal processor that combines the data from the sensors of each of the two cameras to reduce noise and gives you usable images and video. The sensors are made for ultra-low-light capture previously only possible with DSLRs and mirrorless cameras.
Sony makes sensors for their professional mirrorless cameras as well as other Android smartphone manufacturers. But in this case they certainly kept the best for their own Xperia XZ2 premium smartphones. It has two cameras at the back and unlike the iPhone and Samsung phones which has a telephoto lens and a regular lens on each of the cameras, Sony decided to split the capture between a 19 megapixel color sensor and a 12 megapixel monochrome sensor. The dual camera system gives you the same as the iPhone's portrait mode which they call "Bokeh Mode" and you can use the monochrome sensor on its own to capture crisp black and white images.
When shooting video it's possible to slow it down with the amazing 960fps at 1080p resolution capture, which is something most professional cameras can't even do. It's one of the first mobile phones to shoot 4K HDR.

I think it's impressive that a phone can capture low light images to the level where 51200 is needed; that's better than the eye can see. What I think they should do is rethink their naming of their phones. XZ2 doesn't say as easy as iPhone or Pixel, and if they want to sell devices in the US and other English-speaking countries, an easier name would certainly be to their advantage.
It excites me to think that if this is the level of technology going into a phone, what the next phase for their flagship mirrorless cameras they are developing will have.
