On 9/3, my Fenix 5S stopped tracking my stairs, on a run 9/5 elevation was not tracked, and temperature was a constant 120*, same for a run on 9/7. Friday was about 20* cooler them Wednesday. My Altimeter is staying the same no matter where I am, the barometer is plain wrong wrong at 276.17Hg, when I look at the temperature widget it shows 581*, again just plain wrong. I have tried soapy water, calibrating the altimeter, upgrading to the beta software, and a reset. As a Water Fitness instructor I am in the water constantly but my pool had been on a shutdown for cleaning and I hadn't been swimming or teaching for 2 1/2 weeks until 9/4. This is my second factory refurb that I have had about 3 months with similar behavior happening. Any ideas why this keeps happening and how to prevent? Or how to fix this watch? This is very frustrating to replace my watch every three months.
