This morning I received a call on my cell phone and received the normal "new call notification" on my Forerunner 230. I answered the call and went on with my day. Around noon I noticed my phone's smart lock was not working. Usually that means loss of BT connectivity with the watch and reboot of watch will solve the problem. When I looked at my watch it was still showing the incoming call notification from earlier in the morning and would not respond to any input. So I held the light button to power cycle it. Ever since then my watch has the wrong date and time. I am able to successfully sync both by initiated from Garmin Connect app on phone and by the menu option on the watch. Still the time will not display properly. Rebooted both devices. Still no help. I reverted my watch face to the default one. So that's not the problem. I also reset the watch twice by holding the light button for 15s. No help. What next? Only had the watch for 1 year. Is it garbage?
Update: I tried "Restore Defaults" option on watch. Of course had to reset the preferences, but also has to repair to my phone (Samsung Galaxy S6 Edge). Before pairing the watch indicated 9:46am Wed Jan 3rd. After pairing and syncing the time updated to 3:49am Wed Jan 3rd. (The real time was 2:42pm Fri Jan 5th.) What is going on with this thing??
Update: Issue solved by activating GPS by starting a workout.
