My Samsung Galaxy S9 will ALWAYS start filling in a text reply to the last text received (after I put my phone down, in my pocket, in my coat, etc). These are hardly ever sent, but once or twice they have been. They sometimes have a word or two, but are mostly complete gibberish. What is making my phone "write" these replies? Here's one sent to my daughter today: "Gizzards z thus tekci (crying-face emoji) 5 (frowning-face emoji) pes t66 (angry-face emoji) 4 (angry-face emojii) # (crying-face emoji). WHAT THE HAY?
