Solved! How do I orient my nextbook to landscape?

Solution
If it's stuck, check in the options to make sure rotation is enabled. Try rebooting if it is. If it's still not working to auto rotate, you may have an issue with the sensor. There are apps you can get from the Google store to check sensor function.
