This started after I switched to an overseas SIM card. I thought it might get better when I put my ATT sim back in, but it did not. Siri works fine if I activate her via "raise to speak." If I activate her with the long home button press, she appears on screen as usual, but she can't hear anything I'm saying. I tried "reset all settings" but the problem persists. Does anyone have any other suggestions beyond "setup as new?" I really want to avoid that it would take out a day of my life. This may have started after the OTA 7.1.2 update - I'm not sure.
