Thanks to both! Trying it now, at least I can receive emoji responses correctly now, not sure if I can send them
Sending them requires the proprietary RCS protocol. Only google messages and a couple others can do it. Infrastructure for RCS is owned by Google, Apple, and some carriers IIRC
It doesn't, actually. Google Messages implemented this before Apple got RCS. It's as simple as seeing a message come in that says " liked message" and converting it into a ๐ response for the referenced message. Unfortunately no one has followed their lead on that one.
That is why I said sending them. You can't send reactions that people can also see without RCS. QUIK SMS converts received reactions into the proper format but still can't send them.
I'm not sure what you mean. Every receiver has a sender. If you send it to someone with Google Messages without RCS, they will receive it.
QUIK SMS implements turning "blank liked message" into the proper format, but that still doesnt allow sending emoji reactions.
I was pretty sure that RCS id centralized and requires using the existing infrastructure, which requires some contract with Google or other providers.
Either way, no open source Messenger (that I know of) exists which supports RCS.
Either way, it doesn't matter. The point is, RCS does not matter. It is not necessary.
I'm using the official Google Messages app on a Pixel 9 Pro. I'm still getting bullshit iOS responses from old-iPhone users. Very annoying.
