When I first got my phone my Siri beep worked. Now that I did the new update, my Siri doesn't beep when I hold my home button. Can any one tell me if they are having the same trouble an how to fix it. I've done everything possible to do in the settings that I've read how to fix it but, still does not work. Now, it does work when I have my headphones on. Hmmm weird!!
