The foldable Galaxy X phone missed its rumored Q3 launch and certainly did not come out ahead of the Galaxy Note8. It is still busy collecting certifications from the Wi-Fi and Bluetooth authorities and now one from South Koreas equivalent to the FCC.
This certification mentions the familiar model number SM-G888N0 but doesnt betray much more than that. The N0 suffix reportedly marks a Korean model. Things are looking good for a launch in the holiday quarter, but when a worldwide launch may happen is unclear.
From Samsungs patent drawings, it looks like the company intends to take the widescreen to an extreme the whole internal side of the flip phone will be covered in a flexible screen. That would make it much, much wider than the S8s 18.5:9 screen.
