I was noticing a ton more errors in my texts on my new Note 7 than on my Note 5 and realized Auto Replace had quit working. Now I can get it to work by opening a text, opening keyboard settings, turning off Auto Replace, exiting, then going back in and turning Auto Replace back on, and then back to the text to reply. Whenever I exit the text and go into another (or the same) thread, Auto Replace is non-functioning again. Anyone else run into this issue?
