Health Service: retrieving heart rate data

I have modified Measure data: health service to collect heart rate data. The app collects data properly while sitting ideally, but when I start walking app keeps updating and not collecting data.

The embedded sensor's instant data is shown in the Samsung Health app but the health service API is not collecting data while there is a movement.

Start by reproducing the issue in the Measure data: health service sample, comparing heart-rate collection while sitting and walking. Trace the sample's health service collection path and verify whether heart-rate data continues updating during movement; done means the app collects moving heart-rate data as expected or clearly identifies the API limitation.
