Mophie Juice pack plus Anleitung Seite 17

Does the juice pack block the speaker, microphone,
camera, or any other ports?
Of course not. In fact, the juice pack is designed to
act as a virtual speaker box! Sound is redirected from
the bottom of the phone to the front resulting in a
richer, fuller sound quality.
Does the juice pack interfere with antenna reception?
Not a chance.
