On the US Galaxy S21, Google is set as the "Digital assistant app" default, yet when my Bluetooth headset does an API call for the native assistant, it is bringing up Bixby instead. When a Bluetooth headset is making an API call for the assistant on the S21, and the default is set to Google, it should be bringing up Google Assistant, not Bixby. This works properly on the S10 and S20, just not the S21 currently. Creating a post for Samsung engineers to review. If Samsung needs a direct response from me, they can @ me or DM/PM me.
have you enabled "Allow Bluetooth requests with device locked" in the device assistance app settings?
settings > apps > choose default apps > digital assistant app > press the setting icon in the device assistance app tab
I have the same problem. From all my BT devices. All my defaults are set to Google assistant and when accessed thru BT link, goes to Bixby.
Any updates on this?
Just found a solution to this. Go to:
Settings > Apps > Bixby Voice > Set as Default > Clear Defaults
Next time you activate the voice assistant from your headphones, it'll prompt you to choose a default app. Choose Google instead of Bixby.
