I wonder if Android Wear wouldn’t work as an OS basis for this - lower power requirements, probably allows black-and-white screens. The problem there is that Android Wear is absolute hot garbage that can’t decide if it’s stand-alone or companion to your phone.
Why is not just targeting raw AOSP instead of Google Android not considered? It seems like you could use modern hardware with that… is it the lack of Play Store that’s the dealbreaker?
I turned it off when it failed to failover to sms when there was no data connection.
Are both me and the recipient online? Send RCS. Are either of us not connected? Send sms. How is that so hard?
Otherwise RCS is just “worse SMS for people with intermittent data connectivity”.
