Update:
Motor G 4G. 2 weeks old, SD card 16 GB 1 week old, system worked fine for a week and then decided that there was no SD card installed, I took it back to the Meteor shop who unplugged the card and re-installed it, the system then ask to reformat the SD card, they did this and of course I lost all of my pictures but it is working again.
I don't like these faults that do not have an answer, will it happen again when I have a lot more pictures on the SD Card that may mean something?
