Is it because of the most recent Marshmallow version of Android that causes words to go all caps when I hold the shift button when finishing a sentence and use an exclamation mark, or a question mark after the final word? It's driving me insane!!! It will randomly capitalize the final word whenever I add either point, and I want to shut it off if possible. It didn't do it on my Galaxy Tab 4 before this one, and does anyone have this same issue, and know how to shut it off?
