Although it is not o many of its specs have already emerged.
What appear to be official press images of the phone have now been published online, all-but-confirming many of the rumours and reports that have circulated over recent months.
As expected, the phone will look very similar to its predecessor, the S8.
It will feature a 5.8-inch, 2,960 x 1,440 display, a 3,000mAh battery, 4GB of RAM, 64GB of internal storage and a single 12-megapixel rear camera that can capture slow-motion video and switch between f/2.4 and f/1.5 aperture.
The S9 will launch alongside a slightly larger phone, the S9+.
That model will have a 6.2-inch, 2,960 x 1,440 screen, a 3,500mAh battery, 6GB of RAM and a dual camera setup, combining two 12-megapixel sensors – one that can switch between f/2.4 and f/1.5 aperture and the other with fixed f/2.4 aperture.
The Samsung Galaxy S9 phones are already available for pre-order and will be officially available on 16 March 2018
