Siri doesn't work
Siri completely died on me. I normally use Siri to set my alarm, but now it always returns "Sorry, I coudn't do that. Could you try it again, please?" or "Sorry, there's something wrong. Can you please try that again?" Nothing works, change name doesnt work, set timer doesnt work, open app doesnt work. Sometimes it returns hilarious results (see picture).
When I restart my phone it works... for a while. Then it stopped working again. How can I resolve this?
iPhone 5c, iOS 9.2.1
