This is on a Samsung Galaxy J3V, 2018 version I believe.
It updated last night and the text format changed. Screenshot below.
Where there used to be just a text box and the keyboard so you could just start typing, now there is the text box and next to it 3 icons to the left. (choices to add stuff, audio, pics, etc.) They disappear when you tap in the box and type but come back after you hit reply. I didn't see any new options in text settings.
I'd like to revert back to the original format
