iPhone 6s keyboard disappears
Ever since I got this iPhone 6s on release day, even before all of the updates, whenever I am in an app and receive a text message the keyboard disappears when i click on the drop down from the new text. This only happens when I'm in another app, never when I go directly into my messages. I thought updating the phone might help, but it hasn't. Resetting the phone also doesn't work.
iPhone 6s, iOS 9.0.1
