When you see the keyboard icon on the bottom of the screen click on it. you will see a arrow to the right of it. Tap on this and it will bring up your selectable keyboards. If you are having a problem making it stay the default keyboard search for a program called SIPchange or DefaultIMWM5. They are both listed in the below post.
