Q: after the update to ios 9.1 siri is not working and when i use my front camera people cant hear me?

Greetings piscitella,

I see you are a new user here in Apple Support Communities - welcome! I hope we find you contributing often in the future.

It sounds as though the microphone on your iPhone is not working properly. I would suggest that you troubleshoot using the steps in this article - Get help with the microphones on your iPhone, iPad, and iPod touch.

Thanks for using Apple Support Communities.

Be well.
