Does the phone know what kind of headset I have and transmits at the correct rate or do I have to select it manually each time I change headsets? I have two headsets I use for bluetooth, one is aptX and one is aptX HD compatible.</P> Mon, 03 Sep 2018 15:54:32 GMT Mannie3 2018-09-03T15:54:32Z https://community.sony.com.mk/t5/xz-series/sony-xz1-compact-bluetooth-audio-codec-default/m-p/3620642#M44351 <P>Under developer Options - bluetooth audio codec default - what exactly does 'Use system selection (default)' mean?
