Is RCS an open standard? I’ve seen some people say it is and others it isn’t and now I’m very confused. Can you please give me a definitive answer?

        Google is the exclusive RCS provider for all carriers in the US and many other countries. The desire for an AOSP android API is for developers to be able to write clients the way they do SMS clients, not to replace Google’s servers—that’s a pipe dream. IIRC, Google actually helped Samsung develop RCS support in their app. I’m not sure why it’s so difficult to implement.
