I have been having this problem since beging of this year.
I tried everything avaialble on Internet except flashing, and dissembling the watch. But no luck.
Non of my sensors work after the update last year. I kept waiting for an update with bug fix for sensor issue the whole year. Yet nothing.
I'm completely dissapointment since Samsung have not taken any actions on this so far. So many users are affected by the same matter.
Is there anyone who got in fixed? I live in Sri Lanka so getting it repaired through an agent isnt even possible. Plus why should i pay for a buggy software release?
