Siri acting weird / stopped working

[Klatti]

Hey,
Siri is acting really strange on my iPhone 6 since a few days.
If I activate Siri it won't recognise my voice input but the colourful waves at the bottom still go nuts. It immediately gives me "sorry I didn't get that". "Hey Siri" no longer works too and I can't Set it up anymore because it doesn't take my voice input in the settings. I've set it up straight after iOS 9 and it worked perfectly fine.
My microphone is working because I can make phone calls and voice memos with no error.
It didn't work on iOS 9 and does not work on iOS 9.0.1 either.
I'm using Siri in Germany. I've changed the language to English but it didn't solve the problem just like a reboot.
Siri is working normal on my iPad Air iOS 9.0/9.0.1 tho. My brother has the same exact problem. Not working on his iPhone 6 but working on his iPad Air 2.

Anyone else having this problem?

Sounds like Siri is mad at you. Have you been cheating on her?

I had trouble sending texts through Siri yesterday. I would say "Text Sarah" and Siri responded with "I'm sorry, I didn't get that"

So I turned Siri off, then turned it back on and it worked fine after that.

Try turning Siri off and back on.

I've done that already several times. I've also changed the language and turned it off and on.
Nothing works so far ...
