Smartphone-tablet hybrid has standard 4.6in phone on the outside and a 7.3in screen that unfolds on the inside

Samsung has unveiled the final design and name for its cutting-edge Galaxy Fold phone that has a screen that folds in half and costs $1,980.

The new device will be released on 26 April in the US and 3 May in Europe, after nearly a decade in the making. The Galaxy Fold literally folds in half like a book to use as a phone with a 4.6in screen on the outside, and unfolds to reveal a large 7.3in screen to use as a tablet on the inside.
