		// Auto Connect code only connects to the last connected device - which
		// is useful in cases like when the phone reboots. But consider the
		// following case:
		// User is connected to the car's phone and A2DP profile.
		// User comes to the desk and places the phone in the dock
		// (or any speaker or music system or even another headset) and thus
		// gets connected to the A2DP profile. User goes back to the car.
		// Ideally the car's system is supposed to send incoming connections
		// from both Handsfree and A2DP profile. But they don't. The Auto
		// connect code, will not work here because we only auto connect to the
		// last connected device for that profile which in this case is the dock.
		// Now suppose a user is using 2 headsets simultaneously, one for the
		// phone profile one for the A2DP profile. If this is the use case, we
		// expect the user to use the preference to turn off the A2DP profile in
		// the Settings screen for the first headset. Else, after link loss,
		// there can be an incoming connection from the first headset which
		// might result in the connection of the A2DP profile (if the second
