In which state do you think is the religion of the Flying Spaghetti Monster?

Thanks for your reply. Unfortunately my phone does not have that setting.

What a cool project!

Thanks, I did not know the option. It was enabled though. I also checked if it did work with the on screen nav bar (under 'buttons') it did not. There is another setting for 'double tap home button'. I set it to open the camera. That does work, but not from the lock screen unfortunately.

Thanks for the hint. But unfortunately that does not work.
