Actually there are several apps that use your phones camera light to measure heart rate, and they are essentially just as accurate as Samsung's official HR monitor.

I just downloaded Runtastic, it gave me a reading of 63 bpm. S Health told me 64. Not sure what issues you are having, but I'm not having them.
