Whenever I say "OK Google" with my screen locked, it will unlock my phone automatically and respond accordingly. How you get the same thing with Bixby? Everytime I say "Hi Bixby" with a command or question, it asked me to unlock my phone first then respond to my question. How do you fix that?
The fact is, I can use Google voice assistant on a locked screen and it will unlock it then run the command/question as normal. Not with Bixby, it still ask for my iris/fingerprint to unlock my screen first before running any command. I tried to add voice unlock but it's not really secure as people will hear my password, plus its the deflect the whole "handless" purpose when our hands are full with something else. Hopefully Samsung will resolve this small issue in the future, thanks! :)
