@alee17215 sounds like your phone experienced some mechanical damage when it fell. The only way to figure out what its going on will be by opening it up and taking a look for some damage. It is possible that some of the flex cables have come loose or that they have gotten damaged. Open it up and post some good pictures of what you encounter with your Question. That way we can hopefully help you out further.
