Since the yesterday indoor climbing, I encounter weird behavior of my watch.
- back light turns on itself and stays like that. I can turn it off by top-left button.
- Back button stopped working COMPLETELY.
- Arrow buttons work fine, but when I long press the middle-left, it does nothing (not entering settings)
- Top left button works fine for back light, but mid long press does not work (control menu does not open). Long press is working returning "Set up Assistance using Garmin Connect"
- Worth to mention, bottom-left and Start button are working fine.
Would like to factory reset the watch but don't know how. Is there any button combination I can use?
Edit. Suddenly, everything is working. The situation above lasted 11-12hours.i will do factory reset anyway.
Edit 2: 15h after the factory reset I am experiencing strange behavior again, but slightly different:
- Start button not working
- Back button working
- Top-left working for both backlight and control
- Middle-left working as arrow. LONG PRESS not working
- Bottom-left the same. Arrow's working, long press is not.
Edit 3: I got into the HW Test menu. Looks like Start button stopped working completely. Most likely there is some HW issue. Other HW is OK.
Edit 4: Looks like water got inside.
