Royole Flexpai
First unveiled at CES 2019, startup display maker Royole’s FlexPai is now the world’s first commercially available foldable smartphone. Unlike the Galaxy Fold, when this one is folded in half, the device can function as two different smartphones. Or, when unfolded, the device can act as a tablet. This is all possible because the FlexPai screen isn’t encased in glass, but rather an OLED display that’s been printed on a thin plastic material, thus making it both scratch resistant and shatter-proof.

Royole’s FlexPai sports a hinge in the middle that enables users to fold it to the point where its two ends touch or unfold it to a 180-degree angle. Best of all, the hinge is rigid enough to maintain just about any angle in between those two points, which means you can fold it part-way to form an “A” shape and have it stand up on its two ends. It runs a custom version of Android, called Water OS, that it designed specifically for the FlexPai’s flexible display.
