Camera working perfectly except for when I press Quick Switch.  The screen momentary shows the Quick Switch ikon and then goes black with a short 'swish' sound.  
I have a few options selected for Quick Switch in the menu but I wonder if there is another setting I have wrong.

The first Quick Select option is to switch from the back screen to the front screen. Check if the front screen is now on as the OSMO Action (1) does not allow for dual screens at the same time to save battery life.

Thanks for that RobCass.  I was checking in bright light and hadn't noticed the front screen was coming on.  However, pressing the Quick Select each time only swaps between front and back screen but none of the other options like Photo or Video, etc.  I'm obviously missing something - possibly there's been an update since the instructions I have.    I've only had the camera a couple of days so still finding my way around.
