My wife and I tested this about a year ago. She had FB Messenger installed on her phone, and there were news reports about Messenger listening to you even when it was turned off.
We started talking about something we had never discussed before, never searched before, and never had an interest in (to test the theory), and within 3 days she started getting ads for that thing on Facebook.
They ABSOLUTELY listen in on you even when the app isn't running.
The FB Messenger app is always listening.
