Text messaging has dissappeared with latest update

With the latest update a couple of days ago I now noticed I can’t send nor receive text messages, the whole app has gone. How do I get it back?
I’m glad tho that with the latest update the clock stays on when opening the phone… Now if they could fix away that enlarged page with orange frame if you tap the screen twice. WTF is that for? Sometimes it happens when you have the phone against your ear!
