One this I am unclear of is how the phone should be placed for sonar. I understand it should be less than 1 meter from your body but what about orientation? The photo in the documentation shows the phone parallel to your body, but other videos I have seen show the microphone being aimed towards the body. Does it matter?
Also does height matter? Should the phone be level with your body or above it? Will being slightly lower than your body cause the mattress to get in the way of the sonar?
Currently I have it placed with the microphone facing me and the phone sitting on a box making it level with my body as my nightstand does not come above my mattress. The data I am getting from sonar is not matching up with the data S Health is pulling from my watch so I am wondering if I have the phone placement wrong.
I have the Galaxy S7.
