A new four-minute video showcases the Galaxy Fold's features, including its hinge, and how apps like Google Maps switch from a large display to a traditional smartphone set-up when closed.
The phone, which is yet to be held by anyone except a Samsung executive, is due to go on sale in the UK on May 3.
Samsung has offered a more detailed glimpse of its forthcoming £1,700 foldable smartphone in action. The Samsung Galaxy Fold's larger display was shown in a video released this morning
The video shows the handset being easily folded and unfolded before it is tucked into the presenters pocket.
It then showcases the 7.3-inch screen's quality when video-calling, gaming, movie watching and taking photos.
The phone aims to provide users with a larger, more portable screen, that also has the latest gadgets.
The phone can be charged wirelessly, and allows users to power other devices by laying them on the Galaxy Fold, as well as Samsung DeX, providing a more desktop-like experience when connected to a display using a USB-C cable.
The Galaxy Fold uses a traditional 4.6-inch smartphone screen, with a second, larger display housed inside its body, which opens up to form a 7.3-inch AMOLED Infinity Flex display. This new large screen allows three apps to be displayed at once.
Many standard smartphone features are included on the device, including a fingerprint scanner, but it also boasts six cameras in total - three on the rear, two on the inside and one on the front of the device.
UK pricing is yet to be officially announced for the Galaxy Fold, but in the rest of Europe it will cost 2,000 euros (£1,738).

The foldable form is the newest smartphone trend for 2019, with Chinese manufacturer Huawei unveiling its own take on the idea at the annual Mobile World Congress (MWC) technology show in Barcelona on Sunday, known as the Mate X.
Huawei revealed the Mate X phone on the eve of a four-day industry event in Spain to showcase new devices.
Chief executive Richard Yu said it would satisfy consumers' demands for bigger screens and longer battery life when it goes on sale in the summer.
But what is less clear is whether it will satisfy users' demands for privacy, with Huawei under intense suspicion by Western intelligence chiefs who fear the company works as a front for the vast Chinese spy apparatus.
