Samsung recently unveiled its much-awaited foldable smartphone at its conference on Wednesday for software developers in San Francisco.

At the unveiling in San Francisco, Justin Denison, a senior vice president of mobile product marketing, showed a prototype with a screen he said measured 18.5cm (7.3in) diagonally. The device is the size of a tablet computer and features a large 7.3-inch screen, but can fold in on itself, shutting like a book. When folded in half, a second screen on the outside means it can operate like a pocket-friendly smartphone.

However, Samsung did not disclose when the device will go on sale, the cost of the phone, and model name.
