I got my 2025 R1S updated Dec. 18 on the day it was released. I'm in Champaign, IL and may have received the update sooner as one who subscribed to the Connect+ service which I love for the extra connectivity. Haven't tested all the new features yet but will in a couple days. So far looks great...
My R1S shows up on my home WiFi Network (Orbi) as Samsung-Galaxy S22 Ultra and like others we have no Samsung products and this showed up only when I connected my R1S. I've only had my R1S for 2 weeks so haven't had a chance to look more into this.
