I have the new Galaxy watch, received on 7th September and after 1 recorded exercise the heart rate monitor is flatlining after 10 minutes.
First run below
Second recorded walk
I am annoyed as I want to keep track of my heart rate during exercise. I also wonder if this effects the calories burned if it cannot record the heart rate correctly.
This appears to be a common theme for Samsung watches as my husbands S3 did the same, purchased Sept 2017, at the beginning of the year.
AndreiV - Sorry no, half term week here in UK so tough to escape but I'm going gym in a couple of hours so should be able to check then, Ill post this afternoon.
What I will say though is during some home bodyweight workouts, planks, burpees etc the HR was exact which is very unusual. Also during the day I'm noticing the HR on watchface changes almost every second which is what my Fitbit used to do, its never done that on the GW. I'm not getting too excited as we have all been here before but it does seem different.
Ill try a treadmill sprint, some weights and corebag stuff in a bit and post the screenshots
I have updated to the ONe UI and report that for 45 minutes run and 45 minutes on the spin bike the heart rate didn't flatline! I also didn't get the stupid message to wear the watch away from your wrist. Is it possible Samsung has finally fixed the hear rate problem?
@AndreiV- ok finally managed to give it a go and good results compared to before the update.
Pretty much tracked all the way through an hours workout no problem, had a flat spot on the cable machine but could have been my wrist bending too much.
Seemed pretty low HR on the resistance training but constant, during HIIT where I was jumping around it was perfect, as was rowing machine and bench presses.
All in all and tempting fate it worked exactly as I think it should have from day 1.
I've noticed also my resting HR has gone down to 56 from 65 which is more inline with Fitbit readings.
Also whenever I used to leave the gym it was stuck on track from let's say 20 minutes ago, that never happened today and was live all the way home. Unheard of on the GW for me.
Long may it last, I'll keep it now if this continues. I'll post the screenshot in a bit
Excersizes tried.. cable machine, bench presses, rower, treadmill, hiit workout with corebags
Here is the screenshot if anyone is interested, you can see the flatline briefly on the cable machine, looks like 10 minutes but it didnt show that on watch.. First 30 minutes low HR tracking on resistance training, last 30 on HIIT stuff fairly high.
Calories burnt same as always so I can only assume thats not related to the HR output, odd as I always thought it was..
From what I understand from my Garmin testing days, to pay an algorithm linked to heart rate was extremely costly and very complex. Garmin use a company called First Beat who are based in Finland or Sweden, or somewhere like that. I believe the algorithm that Samsung use is literally based on age, sex, weight etc, so pretty useless really. Calorie calculations are an extremely complex matter from what I was led to believe.
