   @Eden @Gargron I'm not saying these two exact events are directly related, but positing that this type of behavior is probably in the wild or was at one point.
   
   With all of the performance analysis and battery optimization work being done by FB and Insta to ensure their users can be Engaged For Maximum Time^TM I really doubt this was a glitch in their app that was unnoticed for over a year.

     @Eden @Gargron facebook & instagram on iPhone both activate the microphone in the background for a split second. It's the cause of many people's issues with bluetooth audio breaking in Teslas. I observed the screen changing for a split second to the bluetooth microphone / "telephone" icon, then going away.
     
     All issues subsided when we went into app settings for Facebook and Instagram and disabled its access to the microphone. Everyone I've talked to with this issue has reported success when following this procedure..... I think micro-sampling for tones is being actively done right now.

     @Eden @Gargron *maybe* the issue at hand is that Facebook and Insta are doing that to bypass some iOS background process restriction by opening up the mic for a moment to cause some internal timer to reset so the worker process doesn't get killed.
     
     Maybe. I'm skeptical Apple wouldn't have noticed though.
