Why doesn't the speakerphone function count as the use of an electronic device?

The speakerphone function is considered part of the normal operation of a telephone because it allows users to communicate without needing to hold the phone to their ear. It utilizes the existing hardware and capabilities of the phone rather than being a separate feature or device. This natural integration means that using a speakerphone does not constitute the use of an electronic device in the same way other distinct electronic devices might be classified, which could have separate regulations or restrictions. The inherent design of the phone includes speakerphone functionality as a standard feature, which is designed to enhance convenience and accessibility in communication.
