My GW (42mm) worked nicely for the first 5 or 6 weeks and suddenly all the sensors just stopped working. I get them to work again eventually by factory resetting the watch, sometimes more than once, but they stop working after a couple of hours.
I thought the new firmware version (R810XXU1BSA4) would solve the problem, but it didn't happen. I thought it did when I updated, got all things working as expected. But in the next day the sensor nightmare stroke again.
