You won't have heard of Oukitel, but this unknown brand had me remembering - and longing for - the times when phones were fun ...

By eschewing a conventional rectangular, slab-like design and app-centric software, the startup is hoping to draw attention as a funky alternative for people who don't live on their smartphones.

That means it separates itself from the base model's rounded-corner design and is instead an aggressively rectangular slab of glass, with flat edges on the top and bottom.

Slabs of broken marble were placed into rectangular moulds and the resin then poured over, before being left to harden. These pieces were then attached to one another using adhesive glue.
