Just in case you're interested in buying a Moto X4 from Google Fi be aware that they are not updating the operating system like they have in the past. I just got my new phone today and ran the update and it's still running 7.1.1. I'm just coming out of the old Nexus 5X and it was updated to 8.1.0! Evidently unless you buy a $600 or $700 phone they're just going to ignore you and act like you don't deserve to have the operating system.
