Has to be better than frozen assets or a frozen shoulder, but still a nuisance - has anyone else had this? I set it up to record a run, and it gets stuck at the "Wait" stage when it's waiting for gps and the buttons don't work - can't go forward to start the run, can't go back to wrist-watch mode, can't switch it off.
It's about 4 years old, which seems a bit soon for it to wear out.
