Thanks for response. Sadly it doesn't help.
I do have a 4 digit pin pass code. Unfortunately, whilst you think it would lock the phone and prevent any operation - it simply does not overide the voice control. If the button is held down for about 3 seconds, voice control switches on. Seems a daft and illogical feature to me - as well as being frustrating.
