Make a Hands-Free-Call
This is a great feature for people who need to make calls while on-the-go. If you have “Hey Siri” turned on, you can simply say something like “Hey Siri, call mom on speakerphone.” Siri will call mom and put the call on speakerphone automatically. If not already enabled, you can turn on “Hey Siri” in Settings > Siri & Search > Listen for “Hey Siri.”
