This worked but raises question for me.   How did this break in the first place?  I manually check for firmware and watch app updates daily (Looking to get the HR issue fixed) and there haven't been any in a while.  There definitely hasn't been a firmware update, I reported getting ...ARG1 on the HR thread when that happened August 9th.   Can Samsung somehow change watch settings/update code via the diagnostics? ...

On the US forum a Samsung moderator replied that there is a software fix in the works: https://us.community.samsung.com/t5/Wearable-Tech/Gear-Sport-Not-Tracking-Heart-Rate-When-Exercising/m-p/401950/highlight/true#M37147   They also suggested turning off specific activity detection and restarting the device which at least for me never helped. ...

For a second there I thought it was better, then I was slapped back to reality.  Please Samsung, I'm begging you.  Notice I don't even use auto pause because for a few rides that seemed to help, but then this happens.    This is directly after restarting the watch before the ride and making sure it was measuring a heart rate before starting the activity.   Still not working ...

Just to chime back in, mine is getting worse.  I used to get good data using the eliptical workout but now I get flat lines doing those as well.  I'd post screenshots if Samsung wants to see them.  I also notice when HR mode set to Always it reports my HR jumping to over 100 randomly when I'm sitting at my desk at work which isn't real.  I believe someone else here reported that as well.   We all know this is a low priority for Samsung due to the impending announcement of the next version. ...

This product is being replaced by the Gear S4/Galaxy watch and Samsung clearly doesn't care about existing customers of their products.   I did 3 rides since July 4th, all HR data is garbage.  I'm tired of posting details trying to give as much information as possible when all the time and effort is ignored.  I would love to assist in any way I could if there was feedback from Samsung. ...

Ricky2, The sweat was another factor I saw mention of (maybe on the US forums).  I'm sure it is not a valid point either.  I'll find out for sure tonight as I play tennis tonight in 90+ degree Farenheit  heat. ... View more

Hello,  Unfortunately I went on 2 mountain bike rides, Friday and Sunday.  As you can see below the HR data is garbage.  I did not change my settings from my "successful" ride from last Wednesday.  It was considerably hotter here than it was on my Wednesday ride so I was sweating a lot.  I've heard some people discuss sweat as a possible issue.  I'm not sure of any more data I can provide to help Samsung fix this issue.  If anyone has suggested settings to try or other ideas I'm all ears. Settings I used, workout tracked with the native S-Health workout tracking on the Gear Sport Cycling Autodetect: Off Auto HR Settings: Always Workout Type: Cycling Target: Basic Workout Auto Pause: Off Location: On Started manually Friday Ride Sunday Ride ...

So I went for a mountain bike ride last night. Settings I used, workout tracked with the native S-Health workout tracking on the Gear Sport Cycling Autodetect: Off Auto HR Settings: Always Workout Type: Cycling Target: Basic Workout Auto Pause: Off Location: On Started manually   This data looks much better, no flat lines, and I was working pretty hard.  This data also resembles what I would get last year on my Gear Fit2.  I would like to use the auto pause feature and turn off the HRM mode from always but so far this is the best result I have had, and by no means do I consider this issue resolved.  Just more data for Samsung to use to find a fix. ...

TheRugbyProp,   There are 3rd party apps like Sporty Watch:  http://www.qooapps.com/sporty-watch.html on the Gaaxy app store that support a chest strap and possibly other types or HRMs.  If you want to pair it with just the watch natively, it isn't possible at this point in time. ... View more

yolesnoobs, I had hope for almost a day I might have figured something out.  Thanks for letting me know.   Ricky2, If I switch to a 3rd party it's not going to be an app.   Funny thing on the US forum someone posted that the ARE2 update software fixed their issue and a Samsung moderator posted a reply.  That was the fist moderator post in the thread.  Extremely frustrating. ...

I agree and I'm betting we do the same thing but my screenshots are showing it is trying to record an auto workout at the same time as the manually started one.  Did you check the setting I mentioned? ... View more

Ricky2,   When you do a cycling workout, do you start it manually or let it auto detect?  I always start it from the workout selection manually, but what I noticed yesterday is that when I start a manual cycling workout the Gear Sport also creates an auto workout during the same time with HR data (I'm not sure if it always does this but recently I've at least had a partial second auto workout).  I'm wondering if the watch can't handle tracking both at the same time.  I'll put up a screenshot or what I'm talking about shortly.  For now I went into S-Health on the Gear Sport, scrolled all the way down to settings and under workout detection, and Activities to Detect,  turned off cycling.  I'm not riding until Wednesday to see if anything changes. My manually started workout with HR and GPS The Auto detected workout Showing the 2 overlapping workouts ... View more

I did 3 workouts this weekend, 2 bike rides and tennis (I use the elliptical workout for that).  It appears the elliptical gave plausible results.  The bike rides definitely are flatlining at certain times. The road bike ride I turned off auto pause(It didn't help).  I have also tried to set HR to Always on before starting an activity(It produces the same results).
