I have exactly the same problem, though my screen is black for nearly 30 seconds. It could be coincidence but I only noticed the delay after switching to a 64gb SD - not that it should make a difference since the camera records to internal memory. Confused and frustrated
even after 108 (2nd edition) and a several tries with different microSD cards, my wife's Z1C still has issues with the camera. The only thing that fixes it for a while is clearing the cache for the Camera app.
If its not hanging, black screening, or rebooting - I effing give up. Can Sony ever get it right??
