Yesterday I did two updates. The Bixby update, and updated the new available version of Android. Since then, I cannot say ok google in my car. After trying 50 times it heard me say it once and then stopped working. Any ideas on how to fix this?
ok Google is a feature of the Google app in the Play store. try updating yours. Or toggle it off/on and retrain the voice. if nothing works sign up for the beta and try the current beta.
