As promised by the company, the Honor 7X Oreo update has started rolling out in the United States. Arriving as EMUI 8.0, the update brings along several enhancements (in addition to the usual Oreo goodies, of course).
The list includes the face unlock feature, a new floating navigation dock, updated Setting menu and Phone Manager, phone gallery recycle bin, as well as ability to connect with two Bluetooth devices at same time. Project Treble support is included as well.
Given that the roll out has just begun, it may take time for the update to reach all units in the country, so you need to be patient.
