My wife and I both have S8 and after we upgraded we found the new chat feature between our phones to be extremely annoying. Instead of sending our messages as actual text messages it tries to use data. The main problem is that there is sometimes up to an hour gap before we receive each other's messages. While I can disable it in the messaging app settings it enables itself after the messaging app has completely closed. I would like a way to permanently disable this feature so we can just text normally. And I am sorry if this question has been asked before but I was not able to find it searching.
I keep changing the default message type to text but it changes back.
I'll add a picture of what I was talking about just in case.
