iPhone - Speakerphone Button UI - Disable Choices

I am writing in because this bothers me enough to take the time to write in about it.

When I am on a phone call, and i want to enable speakerphone, i have to go through 2 keypresses in order to make the phone go to speakerphone. This is because they added an option to take the call on your bluetooth device or macbook pro. I _only_ want the speaker button to be mapped to enabling SPEAKERPHONE.

Apple, PLEASE PLEASE reconsider the UI choice that you've made here. It is infuriating and may lead to people in the car getting into crashes. I understand the desire to consolidate buttons, but this means that I need to do TWO presses instead of ONE for enabling speakerphone.

I do NOT wish to disable the handoff/call transfer feature, so please do NOT propose that as a solution.
