The rule also mandates universal Bluetooth standards and volume control compliance for all smartphones.

      Not officially, but nearly every device has supported hearing aids compatibility for years, well before smartphones became the standard.

      I recall it being required in cars. IIRC all cars after 2012 needed to have bluetooth and hands free.

      Perhaps phones just operated in proxy to that
