It worked!!! Follow these steps: 1. Clear cache and data of (1) bixby voice, then (2) bixby vision, finally (3) bixby service. 2. Turn off your phone (not restart). 3. Turn on mobile data or wifi. 4. Press bixby button or swipe to the right to open bixby. Here, settings will not appear. 5. Press the vertical dots (menu). 6. Click on "Settings". 7. Look for "Bixby Vpice" with toggle option. 8. Click on that toggle option and you are set to initiate again bixby voice activation. Hope this will help.
