I have a new Fenix 6X Sapphire. Xmas present a week ago. I had to return it to the shop as it turned off as I was cycling through the widget loop using the 'BACK' button from Watch Face.
The shop replaced it after they tried to update it and reboot - but to no avail. I now have the replacement. To be clear I have edited the loop so it has about 30 widgets on it and it worked fine all day today as I cycled through until it decided to start turning off before I got to the last widget and Add at the bottom. Just like the previous one.
No idea why. I have downloaded some 3rd party apps and it seemed to happen after that but I can't see why it would.
I am very impressed with its functionality so far but this is disappointing and getting v frustrating.
Any ideas?
