Samsung went bonkers on biometrics with the Galaxy S5, equipping it not only with a Finger Scanner that lets you unlock the phone or authorize secure payments, but also with a heart rate sensor. The optical pulse meter is situated next to the LED flash on the back, and is very ergonomic to use, as it requires a simple stretch of your index finger. he margin of error between the two methods is rather insignificant to warrant the inclusion of a dedicated heart rate sensor on the phone. Granted, it looks and sounds cool, and has that “wow” factor for bragging in front of friends or relatives, but in reality you can do a similar job with a free app on any Android device.
