My wife's Kindle Fire is stuck in portrait. When she first asked about it I hunted around the settings and could find nothing. She had just begun a new book, and thought maybe it was only formatted for portrait. Now she is on a new book and it still stuck on portrait. It does not rotate at all whether reading a book or anywhere else in the system. I'm hoping that this will be a facepalm thing and I am missing a setting. I really don't want to go the warranty route. It is completely stock and is not rooted. Thanks in advance for any suggestions.
