Unfortunately this is what makes iPhones "iPhones"
They bring out features that generally make the phone part of the smartphone better to use.
RCS is still a mess on androids. And calling on iPhones is about to feel very modern while android phones will still be calling people the same way people did 20 years ago.
I have 2 friends with different samsungs and both my parents with newer samsungs. Neither one of them have RCS. Idk if you have to enable it or anything.
Is there even a difference between how iPhone and android calling 'feels'? They're both the exact same as 20 years ago lmao its a phone call, it's been replaced by like a thousand apps by now
