If you thought Samsung would stop making foldable gadgets after the Galaxy Z Fold and Galaxy Z Flip, you're wrong.

Samsung has used this week's CES event to unveil a range of foldable devices, including three foldable phones and a foldable notebook, according to Android Authority and an official press release.

First up, a pair of foldable smartphones. These prototype designs are codenamed “S” fold and “G” fold, for reasons that will become clear later. The “S” fold phone uses three panels to fold out into an S-shape. Samsung says this will be useful for increasing the maximum size of smartphones in the future.

The “G” fold also uses three folding panels, but they fold inward to somewhat resemble the letter G. The company says this design benefits phones made for outdoor activities like hiking, as the inward-facing G-shaped fold allows the device to be stowed almost anywhere without scratching the display.
