So I've got an iPhone 7+ on iOS 10 and I recently came from an iPhone 6+ on iOS 9. I'm finding this really annoying thing with the keyboard while typing on iOS 10. When I press the '123' to change to punctuation mid sentence, then insert a comma (or similar), then do a space, my keyboard isn't flicking back to the letters automatically which is really annoying. Because I'm finding myself typing a load of symbols only to have to go back and manually switch to letters and rewrite the sentence because it hasn't switched back. Where as it does on my 6+/iOS9. How can I change this?
