How exact is measurements using the HR sensor? 

Q : How exact is measurements using the HR sensor of Galaxy S5?

A : Because your Galaxy S5 measure heart rate using similar method with existing medical equipment’s, it has
almost same inaccuracy. But, the device’s heart rate measurement feature taken by S Health cannot be used
for clinical or medical diagnosis. While the measurement is being taken, you do not move or talk , and wait until S Health
has completed the measurement before taking your finger off the sensor.
If the measurement is very different from the expected heart rate, rest for 30 minutes and then measure it again
