I have had the same problem when exercising also even though i have HR “always on” sometimes it will just stop measuring for 5/10/15 mins until i notice and leave it on the HR widget for a good few minutes. Today i restarted the device and it seems to be working better now. However just now it cut out again, the green light on the HR monitor wasn’t even on. Ill have to test it out again tomorrow when running to see if it flat lines again as it has in the past. If it keeps happening I’ll have to just return it and go with garmin instead. The screens can’t compare but they have better battery and are way more comfortable.
Software version: R800XXU1ARH1
Update: I've updated to R800XXU1BRH3 but I'm still having similar problems. Took it out for a run the other day and the heart rate stopped tracking 5 minutes in. Will do some more testing but if this continues I'll have to just return the watch
I've experienced all the same HR issues mentioned in this thread. Last night i saw there was a new watch download available. So far so good. I have HR 'always on' and on a cycle this morning I experienced no issues. Here's hoping !
Software version: R800XXU1BRH3
Others have mentioned a software upgrade as well, but I don’t see one available. Do you have the new Samsung Watch or the s3? I have the new Samsung Watch, and on my phone, I go to “ABOUT WATCH,” then “Upgrade watch software.” It tells me that I have the latest software, which is the same software I have had since I got the watch a few weeks ago.
Yes I have the same recently launched Galaxy Watch. I followed the same path on my phone as you did, and selected 'Update now' and down it came. I am in Ireland on 3 network, so perhaps it is rolling out to different regions at different times.
That is the software version I already have, and I am still experiencing all the heart rate problems.
Yes there are still issues with heart rate, sleep tracking and the algorithm used for how many steps you take before it starts recording, but I understand a new software version is being tested at present so hopefully that'll help. Also the engineers are aware of the issues so I'm quite hopeful it'll be sorted. If it turns out to be hardware then I'll expect Samsung to give me a brand new replacement rather than a repair as we've had these issues since day 1.
Hope there will be an update in Sweden this week, else I have to return it. Is seams to work when I walk around the house but if I take a simple walk outside it goes crazy .. :(
