Hello, I was in the middle of using Siri on my iPad mini with Retina Display, and while I can use Siri, I can not exit Siri, nor can I power off. I have the most recent update. What’s up? How can this be resolved? It will not respond to holding the on/off button on the side. The rotate screen is also not working. Siri talks to me and finds me stuff I ask for on the Internet by voice, but the iPad mini screen is totally unresponsive to any swipes. I tried plugging the iPad into my Mac Laptop, with iTunes on, but the iPad just dings at me and the screen text goes on and off in the process of ding ding ding ding … so I unplugged it from the computer. Any solutions please?
