The ultimately strange device has just been certified - Samsung SM-W2016. 

What is extraordinary is that it will be a flip phone with curves od sides like the S6 edge. 

 It has two identical screens (one outside the flip, one inside) – 3.9" Super AMOLEDs with 768 x 1,280px resolution (383ppi).

It offers us  an octa-core processor (allegedly the Exynos 7420 itself) with 3GB of RAM and 64GB of storage. The phone runs Android 5.1 Lollipop (Samsung is yet to make the jump to Marshmallow).
