How to remove Read Phone State

I am using Unity 5.3.6 and for some reason the permission Read Phones state is a part of my build. I have read up about this and it seems that it has only been a problem for much older versions of unity, so I am confused as to why this is a part of my build when I am not using this. Is there something that i could have done to have this added and if so how could I undo this? or is this still apart of unity in the version i am using?
