I had a moment of paranoia in the theatre recently. I turned phone off, couldn't remember if I'd turned the phone off, then realised the only way to check the phone was off was to press the button at the top, which if the phone was on would bring me to the screen unlock thing... but if it was off, would turn it on.
Is there a way to check its 'offness' without turning it on?
