Flip phones largely died out when Steve Jobs introduced the game-changing iPhone, but Samsung thinks it's time they came back.
But this time, there won't be any hinges - and there might be touchscreens on the outside.
How the phone's hinges might work (Samsung)
The Korean giant, which will be hoping for a massive hit following the exploding Galaxy Note 7 fiasco, has filed a patent for the technology.
From the drawings, it appears the phone will be able to be bent at a number of points along its length, rather than straight down the middle like old-school flip phones.
A "secondary display" will grace the back of the phone, and will activate when the main screen is folded away.
Several tech news sites quoted Kim Don-won, an analyst at Hyundai Securities, predicting the first foldable phones will hit the market in 2017.
He says they will probably be quickly followed by offerings from Apple and Google - the latter of which recently unveiled what it hopes will be an iPhone-killer, the Pixel.
