Why do I need to go through a multi-step process to initiate a call using my bluetooth headset? I first need to swipe the screen, then wait 5 seconds while a warning message displays. On any other phone I've had, I could just tap the call button on the headset and say who I wanted to call.

Sounds inconvenient.  All of my phones were like your old phone.  Perhaps a setting within your call/phone settings or in the bluetooth or accessibility options.  Some BT devices might have a gear or separate menu of their own within the BT settings menu that you can change.
