Hello! 'Hey Siri' feature does not seems to work on my iPhone 6+, but works successfully on iPad Air 2 (both with iOs 8.3b3). Siri is working well on both devices, but reacts to 'Hey Siri' only on iPad. Does something like this happens to somebody else? iPhone is connected to power source, 'Hey Siri' feature is enabled in Settings and Siri have access to work in the lock screen. I was trying to restart the device, hard reset, reset the Network settings and manually turn all of the Siri-related settings off and back on again - this does not help, unfortunately. Any glues? Thank you!
