Electronic devices and corresponding methods for establishing geofencing for enhanced security modes of operation

One or more sensors of an electronic device detect either authorization of an authorized user or a cessation of physical contact between an authorized user of the electronic device and the electronic device. A location detector determines a location of the electronic device when the authorization of the authorized user occurs or where the cessation of physical contact occurs. A geofence manager establishes a geofence about the location in response to detecting the authorization of the authorized user or the cessation of physical contact. One or more processors operate the electronic device in a normal mode of operation while the electronic device remains within the geofence and in an enhanced security mode of operation when the electronic device exits the geofence.
