Samsung is set to have a busy year in 2019.

The Korean tech giant is expected to launch three Galaxy S10 models, as well as its long-awaited folding phone, by early next year, according to Bloomberg. 

A folding phone has been in the works at Samsung for many months now, with speculation of such a device first bubbling up over a year ago. 

Bloomberg said Samsung's foldable phone is currently being developed under a secretive codename called 'Winner,' which is line with previous reports that made the same claim.  

The firm is mulling over two prototypes - one of which is longer horizontally, while the other is longer vertically - with designers preferring the portrait model, as it's easier for users to hold than a landscape design. 

It would also have a four-inch screen on the outside so that users can check their messages and notifications without having to flip it open.
