Q : When trying to measure heart rate using Gear2 and Galaxy S5 simultaneously , heart rate measured
from each device are differed. What’s the problem?

A : To measure heart rate, Galaxy S5 place your index finger on the sensor at the back of the device, but Gear2 or
Gear fit need to wear the device around your lower arm just above the wrist.
While the measurement is being taken, movement of your body or finger from sensor may cause your heart rate
to be recorded inaccurately. Additionally, users with thin wrists may receive inaccurate measurements. Inaccurate
measurements occur when the device is loose because the light reflecting off the wrist to provide the
measurement is uneven.
As a result, slight difference between Gear2 and Galaxy S5 may cause, but If the measurement is very different
from the expected heart rate, keep in mind the caution point then measure it again.
