how to stop iphone change from speaker to audio
I have an iPhone 12 Pro.
Bluetooth is OFF and is never on.
I have removed facetime.
I do not have linked calls set up. I never have had linked calls on this phone.
The speaker option changes to audio every few days. I turn off and on the phone and this resets back to speaker.
I want to permanently stop my phone changing from speaker to audio as I have no requirement for audio options.
There must be something I am missing as it has been just plain speaker previously.
