Here is what Samsung's upcoming foldable smartphone may look like
The South Korean company filed at least half a dozen patents that contain schematics of what appear to be foldable phones. The last one dates from this week and may give us a clue as to where Samsung wants to go with this so-called “foldable smartphone.”
However, in this case, the “secondary screen” is much bigger and may probably be used for more than just shortcuts and notifications. The display is rounded 180-degree on the side of the phone and doesn't even give you the impression that it would be split in two. In fact, maybe it's just a single massive display that's used for different purposes.
