That's exactly what I was going to say.
I use the Samsung Message App.
So I don't need/want Google message.
But, before I disabled it, I turned OFF the auto update.
Then I took the extra (probably unnecessary) steps of uninstalling any/all update/s which meant it reverted back to the most basic version of the app.
It also meant less of my phone storage was being used too.
Finally after all that I killed it by Disabling it!!
Yeah, I know someone will probably say I shouldn't have done that-but I've done this with other Apps on my previous Galaxy phones.
