I generally like Siri and use her most often when I am driving and my iPhone is in its cradle and charging etc When I'm in my car my iphone is connected to my car via Bluetooth. With iOS 8.3 whenever I ask Siri to call someone, she now calls them on speaker, rather than using the Bluetooth connection with my car. It is very annoying, as then I have to touch the phone while driving to take it off speaker and onto the Bluetooth connection. How do I stop Siri from dialing people on speaker? When I ask Siri to dial, I never say, "call John on speaker", I just say "call John" etc How do I fix this very annoying problem?
