Picture this: A big-screened smartphone that folds in half to fit into your pocket.

Samsung could reportedly release such a smartphone as early as next January, according to SamMobile, a blog that covers Samsung and has a history of providing accurate information on new Samsung products ahead of their announcements.

The report claims a Chinese insider with knowledge of the product insists Samsung is currently testing a smartphone — so, no, it's not a flip phone — with a foldable display. The rumored device could come in two models with 3GB of RAM, a microSD card slot and a non-removable battery; the only difference would be the processor, which could be a Qualcomm Snapdragon 620 and an 820 chip.

Otherwise, not much else is known about the rumored device. The report also says the phone is not the Galaxy S7 and could only be released in South Korea. That's not unusual; before Samsung settled on the dual-curved edges for the Galaxy S6 Edge and S6 Edge+, the company released the Galaxy Round, a phone with a curved display that was only ever released in South Korea.

With Samsung's phone sales looking troubled these days, the company has been forced to differentiate its devices with features like dual-curved displays and the S Pen stylus. A phone with a foldable display could be exactly what Samsung needs to win back customers who have defected to cheaper Chinese devices or Apple's iPhones.

A foldable display isn't without precedent. In 2008, Samsung showed off a prototype of a display that folds in half at The Society for Information Display (SID), an event that showcases innovative display technologies. You can see the prototype display in action in the video above.

The company has also showed off a concept video for a foldable phone that expands into a tablet.
