Ok thanks. That sucks. I mean, being able to say "hey google" or whatever, even use the assistant on the lockscreen, is pretty pointless, since you have to touch the phone anyway, and you can quickly unlock with fingerprint, plus most features will ask you to unlock before you can use them.
And the security risks make sense, but I would like the choice, if I'm at home, to remove that restriction. So, if I'm on my own wifi, I could use it even with the screen off. But I guess that might drain too much power, also.
