Hello, I have a new Samsung A50. I am using Bixby for my assistant. I have disabled Google assistant. When I attempt to use my Bluetooth headset, and push the voice command button on my headset (for Bixby), I get prompted on my phone to choose a voice service, "Bixby Voice Just once", "Google always". If I push "Bixby Just once", Bixby answers, but only once. I have to repeat the process each time I use Bixby with my Bluetooth headset. I don't know how to turn off this prompt so I can use Bixby only. I don't know what Google features will stay active, I just want to use Bixby without the Google conflict.
