That’s been on Android for a while — OK Google, the always listening setting, with screen on or off. I had it on for a bit but turned it off, not just because it was creepy in theory, but also because it would turn on with a ding and “listen for music” all the time, just with the TV on, etc.
I think the latest update addressed the issue somewhat by adding voice training as a mandatory step in enabling the function. Not even Alexa turns it on anymore.
I like the ones that have women dancing on your toolbar...... ah I mean something different....
