I started to use my Galaxy Watch for running - and it has an inaccurate Heart Rate indication during the workout - I believe because of sharp movements and sweat.
And it can be solved with external HR sensor (usually BT/BLE chest strap).
I only found only the solution with custom watch face which can connect to external HR sensors and use its data.
But it would be great to have internal support to use it with Samsung Health, Strava, etc. because HR is one of the most crucial values for running.
The Samsung competitors like Garmin, etc., and even Apple watch, support external heart rate monitors.
I've been looking at Samsung watches lately and have decided that due to the lack of native support for bluetooth HRM sensors I will not be purchasing a Samsung watch. Samsung, please add support for bluetooth HRM sensors!
