I have a Samsung Gear Live sync'd to a Samsung Galaxy 5S. The Gear is set to sync the date/time from the phone. On Feb 29 the phone showed the right date but the watch showed Mon Mar 1. Ever since Feb 29 the date is correct, but the day has been one day back [for today, Thurs Mar 03, 2016, the Gear Live shows Wed Mar 03, 2016]. I have been online with Samsung support. From this I have rebooted the Gear Live and wiped all the data, disconnected and reconnected the watch and phone, and generally tried everything they said, but to no avail. Their current response is to take it into a service centre to be 'fixed'. Samsung, I think this is a problem with the leap year somehow.
