Maybe not a S8 specific question, but in the Samsung message app when I send want to a txt to a number of people (in my case 19, its the parents of my football team) the Samsung message app converts the message (even before I start typing) into an MMS. Is there a way to stop this? I know I could use another messaging apps (I know Chomp/Textra all works fine), but I would rather use the default messaging app.
