Have you ever seen a keyboard on an S7 with mixed uppercase and lowercase letters on the keyboard?

[AC Question]

Almost anytime I start an email or a text a few words in the keyboard switches to a mixture of uppercase and lowercase letters. Sometimes it'll capitalize all first letters other times it wont capitalize when starting a new sentence. Other times the autocorrect goes completely bonkers.. I tried resetting to default settings. I tried turning auto capitalize on and off. I tried researching... I got nothing.
