Problem with Iphone. How can I turn off without touch the Iphone?

Yesterday I updated my Iphone to IOS 7.1.1 and today I was taking a photo with the Iphone blocked. When I finished I just hit the button at the top of the iphone.
When I received a message, surprise, my Iphone was bugged and can't unblock. Tryed everything, I have 98% of battery and the touchscreen don't work for basics actions, like unblock or turn off the phone.

Anyone know how to turn off the Iphone without the touchscreen?

You used to be able to hold the home and power button down together for 10 seconds to power down.

  • Why Can't I Turn Off iPhone Without it Disabling? Every time I turn off my iPhone, when I turn it back on it says something like "iPhone disabled, connect to iTunes" or "iPhone disables, try again in 5 minutes". Is there a way to fix this? I know how to un-disable my phone, but I don't know how to turn it off and on again without it doing this.

  • IPhone lock button broken. Can turn off but how do i turn it on? The lock button at the top of my iphone is broken, but i have been using it fine as i have turned on 'Assistive Touch' and have been using the white dot that appears on screen. However, I'm worried about turning it off, and surely the white dot will disappeaer when the phone is off, and I will have no way of turning it on? Am I correct in thinking this?
  • Iphone 7 won't respond to touch or turn off? Starting yesterday it has been unresponsive. I can unlock it, but after that I can't go into any apps. If I ask siri to open an app it doesn't do it. I tried holding down the power button or the power/home button but nothing happens.
