    OK on the back of the phone under the main camera there is 3 sensors. I know one is the flash and one is heartbeat monitor. Does anyone have a clue which the third one is in there? Just curious and wondering.

    I think it's a dual-flash and the heart rate monitor.

    The flash, and the other two are, together, the heart monitor sensor. One provides light into the skin, and the other detects changes in the light that indicate blood flow, and hence, a heartbeat.
