Facebook listens to your phone's microphone
independent.co.uk<Facebook says explicitly on its help pages that it doesn’t record conversations, but that it does use the audio to identify what is happening around the phone.>
Well, that's comforting.
<Turning off the microphone in a phone’s settings is relatively easy>
Really? Turning off the mic for Facebook (or even globally to apps) without making it useless is "relatively easy?" Somebody, please point out to me this feature on Android.
