The company's foldable phone is slated to arrive in the first half of 2019. It's already generating buzz, and for good reason. Along with 5G, foldable phones are widely regarded as the next big thing for smartphones in 2019. 

A foldable design promises to expand a handset's screen size while keeping the device portable enough to carry around. As the forefront of a bold new design era, foldable phones are also seen as a way to shake up renewed interest as people hold onto their devices longer and phone sales slow.
