A Samsung device bearing model number SM-G888N0 has been spotted at the Bluetooth SIG which has awarded the device the required certification. This model number doesn't correspond to any device in Samsung's lineup right now, hence the possibility that it belongs to the unreleased Galaxy X handset.
The same model number was spotted at the Wi-Fi Alliance four months ago where the SM-G888N0 received its Wi-Fi certification. The Bluetooth certification document shows that the SM-G888N0 is carrying Bluetooth 4.2.
This seems a bit odd because recent flagships like the Galaxy S8 have support for Bluetooth 5.0 so it wouldn't make sense for the company to ship its first foldable smartphone with an outdated standard. It's likely that the device may be bumped up to Android 5.0 before it's eventually launched.
Samsung is yet to confirm when the Galaxy X is going to be announced officially. If recent reports are any indication, it may be released either by the end of this year or by early 2018.
