For example, open Google Maps on the front page and it will show your location in a relatively small map area. Fold open, and the same location is displayed with far more of its surroundings in a far bigger map area. Or, see the same location in far greater detail. Open Netflix on the front, start a movie, and then unfold the handset to carry on watching the movie in a somewhat larger format.
The inside screen can be split into three separate app areas, with one large and two small app spaces. This means one can watch a video or play a game in the larger space, chat with a friend via instant messenger in one of the smaller spaces, and write a document in the third space.
This opens the way for the Fold to join the Galaxy Note as both smartphone and productivity tool, and ultimately a replacement for laptop computers.
That is the real promise of the fold: a digital working surface that is also an entertainment and communications device, and that can be slipped into a pocket.
As with app continuity, the three segments “speak” to each other, in that a browser or app in one window can be dragged to another if one wants to see it in a larger or smaller format.
The specs of the device were also a pleasant surprise: 12GB of RAM, which Samsung says makes it one of the most powerful smartphones on the market. It has a massive 512GB of storage space onboard, and support for universal flash storage, meaning content can be accessed significantly faster than with regular handsets.
