iOS Audio Path Widget

Select the audio path widget from the speaker icon along the top banner or while in call. Selecting the audio path widget displays the available audio options for the device.  This includes connected headsets and available BT devices. Tap an option to bring the selection to the top of the list and brighten it.  

A note about Bluetooth and wired headset devices:  The audio path widget allows you to select the audio path in order of preference.   Bluetooth and wired headset devices that have been previously paired to the Android device will automatically be reconnected when within range.  

The first time a Bluetooth or wired headset device is connected it will always automatically be the preferred pathway. After it has been moved down the list, below the speaker phone, it will stay at that priority level when it reconnects.  An audio device should only be removed completely from the list when the user will no longer use it on the device at all.   If the device has been removed by hitting the "X,"  when reconnected it will always go to the top of the list and become the select audio path.  For best practices, don't press the red X, so that the device doesn't take over the audio stream in future; instead, move the device to the bottom of the list. 

To reach the audio widget, tap the speaker icon on the top of the banner. The option at the top is in use.  The speaker icon in the audio widget refers to the device speakerphone.  The iPhone refers to the small microphone at the top of the device.  Other items on this list could be AirPods, wired headsets, hearing aigs, or car bluetooth.  Drag the items to switch the order as shown.
