THANK YOU, such a simple, quick cure.
I'm most grateful for your video, it worked for me. My power button suddenly stopped working a while ago and has been annoying me ever since. I discovered by accident that the phone would turn on using the camera button, so I could still use the phone but I couldn't power off. Even though it is under guarantee really didn't want to send it off and the care web site is useless. I was also told, when I phoned a care centre (there is not one remotely near me), it would be a software problem and to bring it in. I was hoping that maybe an update might cure the issue. So, I was a little sceptical of your suggestion but tried it any way.
