I put the Siri choice on On to see what would happen and then I turned it back Off and now Siri won't open at all.. It just goes to the voice cover option
I was going through the setting and just playing with my phone and I came along the restrictions and I put in the code.. By accident I turned the Siri restriction on and now when I hold the home button Siri doesn't come up Vocie Control opens
