I've had my Vivoactive 5 since December of 2023. Up until about 3 weeks ago it has been amazing. It's still amazing in all aspects except for the heart rate monitor, which has become very inconsistent over the past three weeks. I walk for exercise every other day (usually between 5 and 8 miles at a pace of 4.0 to 4.7 mph). One day it seems to measure my heart rate correctly, averaging around 110 bpm, and then the next time it says my average heart rate is 67 bpm (which is basically impossible at the pace I'm move). I have compared the reading from the VA5 to a KardiaMobile device I have (due to bradycardia) and they are not even close to the same when I take the time to compare the two when my VA5 doesn't seem to be measuring correctly.
Has anyone else had this problem? If so, did you ever find a fix for it?
Thank you for any and all help!
