Also, if anyone here has a fix, please let me know! Using the GW4 as tool to support exercise and health is a main goal for Samsung, and they are off the mark in this respect.
For me, I have the super-high HRM readings when exercising. At rest, the GW4 is relatively accurate, but it goes wildly off the charts when running. I have submitted an error report to Samsung, and they basically said to do a factory reset, which I am not inclined to do at this moment, given the time it would take to set the watch back up and the fact that I doubt that’s the problem.
So, please weigh-in if you experience the same issue or if you have a suggested fix.
