So the heart rate monitoring on my active 2 is set to 10 minute intervals, but it only measures every hour. I've double checked this by exporting the data.
It's also extremely inconsistent, I usually have big gaps in the day where no heart rate is taken. For example today I have a 6 hour gap.
Yes I am afraid the sensor on my watch is really inaccurate.
Three months old, it has been back to the service center twice. I have used an oximeter, my s10 note and a blood pressure cuff to test it against.
Samsung Australia are terrible they use contracted service centers. Have always loved Samsung products till I got this device. I have tried different wrists , different positions, have done resets on it and had my brother inlaw wear it with the same wild fluctuations, yet Samsung keep sending it back to me because a technician has tested it on a bench , not comparing it to other devices.
It is on its way back to me from Sydney again.
I will let you know how it goes this time but I do not hold high hopes.....
