| You won't find one because it doesn't exist. As a person who's made a living the last few years working in the guts of Android on embedded devices, there are so many holes in this way too common myth that phones are listening all the time. You don't even need to dive into the technical aspect of it, what on earth is the risk reward here?! Risk: Forever break the trust people have in your devices, this isn't some grey area intrusive tracking that would just get swept under the rug... Reward: Get noisy info about people's interests when you literally own the device that contains more information about than their own short term memory does! It's nonsensical, and there's no way that Google could do this that wouldn't already have been caught. I mean is the theory that all Google devices do it and somehow no OEM has realized their microphone is getting accessed? (Because even with the lowest level access on the device, modern microphones are not so unsophisticated, there's no universal way to access it in a way a manufacturer wouldn't catch onto sooner or later Or Google did this but only on phones they own or something? It's nonsense. |
There is no proof it happens, and no proof it doesn’t happen, because it’s non-trivial to detect based on network activity. The only evidence is observing content relevant to what was being spoken about being suggested across apps.

Reward: get people to love your services for relevant suggestions. Believe it or not, there are people outside the extra privacy-conscious bubble who do not at all mind their devices listening.

I am pretty sure this depends on software. I have seen this demonstrated on a Google-branded phone with a Google app.
