Doesn't look like samsung is ready to acknowledge that their HR is broken at the moment. Same thing is happening to me and it's throwing all of my graphs way off within s-health.
The app has a hard time distinguishing between RHR and normal. Super frustrating and should have been tested prior to release. Just hoping for an update some time soon but it all starts with the company acknowledging their faults.
i run my galaxy watch with "frequent" heart rate setting. its been running fine since i got it at roll out (DELAYED pre order delivery by two weeks).
anyway it started to ready 30 BMP today all day. i rebotted it, turned off the ellipitcal and training tracker.
back to normal now.
i had the same issue. rebooting the watch re-activtated the sensor for several hours,then it stopped working.
i got really concerned with readings in the 30s that started one day .
i did a "RESET" and that seems to have stuck.
other than that, the watch does seem to loose the black coating on the bezel relatively easy
Your lucky I have had mine for about 6 weeks wirthin that time its showing a very huigh heart rate which got me worried. Checked it against my Fitbit 2 and Note 8 which both showed a loot lower heart rate around the same figure. Looks like I will just junk the watch and get the Fitbit 3
Same issue for me as well, I go the 46mm. Twice when running it missed completely to track my heart rate (about 20 minutes of running) the third time it got some heartbeats at the end, and last time iiused it for running it tracked the last 15 out of 20 minutes. It says to clean the HRM when I start to track my run. I did so, even took it off and cleaned the watch HRM and my wrist but it did not help. This is not my only issue I also get the abnormally high heart rate readings over 220-250 when I am sitting and not moving at all, or very slightly (which is technically impossible even during heavy workout for me to reach this high bpm). To fix this i change settings from always on to normal (evrye 10 min) and make a manual reading and it then works normaly it goes down to around 60bpm (I also tried this without repositioning the watch or moving it from my wrist same results). From my point of view (or probably this is what I hoping) this abnormal high readings looks like a software issue. But since all the silence from Samsung it doesn't look too good, gives the impression that they just don't give a d**n about us as customers. I am also thinking of returning since changin to a new Samsung watch won't fix the problem. I've had two garmin watches before and never experienced this kind of problems with the HRM
And most definitely this is not solved!
i want to share a fix with you that i found out.
After that my heartrate sensor is working fine.
Please check the following:
Under settings -> apps -> permissions -> scroll down to system apps -> power saving -> disable sensors here.
After that no problems while training compared to fitbit only 1 or 2 bpm difference. I think the problem is power
management here so the sensors do not wake up as fast as they should.
I did try this fix you suggest but still the heart rate is abnormally high. The only quick fix (but just for a while, since it returns rather quick) to turn off HRM always on and do a manual measurement and turn the setting back to always on and it goes back to normal readings of heart rate. As i mentioned before whitout repositioning or moving the watch on my wrist. Feels like it gets jammed up somehow in the software.
After 3 weeks of flatline when cycling I decided to shave wrist hair off and fit watch tight enough so it can't move, job done one & half hours cycling today and no flatline, think I have sorted my problem, will see next time igo cycling
