There is a subtle error in your comment

Rachel did not (despite her testimony) LOSE CONTACT with Trayvon... He closed his phone and put it in his pocket.

I doubt very much if she heard anything, since her stary does not make any sense

If he closed the phone and put it in his pocket, he did it before the fight started.

If he had her hang on to the phone and listen in, then the phone would still have been on when they found him-

Good point.
