Fenix 5 Plus Altimeter has stopped working

With my Fenix 5 Plus, the altimeter no longer works. First the values for an activity were no longer correct (deviation of 1000 hm and more) and now no height is displayed at all. I did the reset and factory settings. Is there a solution?
Thanks in advance Andy

  • Thanks for all that info. Seems the test brings back all sorts of nonsense values so assuming this is a hardware failure. It is a shame as the altitude function is useful on hikes and trail running but I'll run this watch into the ground using it for my swims and running. Appreciate ypur time Data
