I have never used Google Messages but I will most likely have to start using it once RCS support is added on iOS.
I am running GrapheneOS with no Google Play services and was curious if Google Messages would run without it. I am assuming notifications will be delayed but is there anything else?
Is anyone here running GrapheneOS and Google Messages?
Keep in mind that RCS is still SMS to anyone without Google Messages.
Also, the encryption in RCS is problematic - last time I read how it worked I wasn’t convinced it was as secure as advertised (I don’t recall why, but I think it’s because it’s not really E2E).
For a time, RCS was not e2ee, neither in one-on-one or group chats. I think they changed both to finally being encrypted. Obviously, even if they are, the sender and receiver are both known by either your phone provider or Google itself… Or both.
