I have had a new iPhone SE for a few weeks. It works fine, but in the "Health" app, my step length is approximately 0.6 m (1000 steps give a distance of 600 meters), which seems wrong (I used to have around 0.8 m with my previous phone). I also checked with the distance on my companion's iPhone : my iPhone correctly measures steps, but not distances.
Is there any way to reset this ?
BTW : yes, I have allowed the "Motion Calibration & Distance" option in the "Privacy" setting.
