Hi.. Yes when doing developing work on a device or when the device is with the customer we sometimes need to view or change settings within the device
having an escape procedure without the need to connect to pc and would be very useful
What I have done in the past in the case of the file menu being hidden is to add a new session for the sole purpose of exiting the app. Once you enter the this session you can enter a passcode that gets looked up/validated and if it passes will allow you to exit. If it fails it will prevent the exit from happening.
