We know for certain Samsung is working on a foldable phone and aims to release it - in a likely very limited capacity - during 2018, but a new patent application looks different to a lot of other information we've seen about the Galaxy X and suggests it may actually be more akin to a flip-phone than we previously thought.

Certification documents filed in Korea - and spotted/uploaded by LetsGoDigital - show the Galaxy X with a hinge design so you can bend the phone over.
