At its recent Analyst Day held in Korea, Samsung showed attendees a range of prototype folding smartphones.
Reporters weren't allowed in, and analysts were banned from taking photos, so we don't have any images to show.
However, The Wall Street Journal has some first-person accounts from attendees that paint a fairly clear picture.
"The first one they showed us was the size of a [Galaxy] S3 smartphone, which can be folded in half from top to bottom," Daiwa Securities analyst Jae Lee told The Wall Street Journal.
Another device was the "the size of a lengthy wallet, which can be unfolded on both sides into the size of a tablet computer," Lee said, adding that both of the devices looked pretty good.
While the first sounds a little like a fancy clamshell phone, the second sounds like a really quite innovative blend of smartphone and tablet.
Samsung has said that it wants to formally unveil foldable phones by 2015, but the shift from glass screens to a bending plastic may take some time to arrive in retail. In the meantime, we have the curved Galaxy Round to tide us over.
