"Hey, Siri" not working - iPhone 6/IOS 9.2.1
Siri can't seem to hear me anymore. Hey Siri not working when plugged into power source, and home button Siri not working correctly either. When the home button is held down, no double beep is heard, instead a double vibration is felt and Siri doesn't "hear" anything. When Siri is turned off, Voice Control works fine.
Any ideas? Thank you!
