> When I had a Samsung galaxy I had to go pretty far out of my way to install google's messenger and use it instead of the Samsung SMS client. I'm pretty sure that' will be similar for the vast majority of android users. This would only be the default SMS application on google's Pixel phones. However, maybe carriers' and OEM's SMS applications are now integrating RCS protocol as well. Samsung does support RCS and interoperates with carrier and Google RCS servers (that is, "it should just work" if your carrier didn't deliberately try to block it). However it's not clear if they're implement the E2E encryption part of the spec. The big difference in practice is that carriers can mess up your ability so send those messages - something that Apple rightly never allowed with iMessage.
