Verizon has pushed out a number of updates since the beginning of November. The Galaxy S9 and S9+, Moto Z DROID, RED Hydrogen One, and a couple of Galaxy Tab A device have all picked up new software.
Most of the updates are nothing but security patches. However, I’m assuming that the RED phone is getting more than just a security patch. A bigger update is supposedly headed for retail phones at launch. The changelog only says that the update “improves your mobile experience with user experience enhancements and fixes.”
To check for updates, head into Settings>System update.
