Compass and Measure app not working.
To my surprise, all of a sudden Apps based on motion sensor are not working. Compass, Measure, Health app etc are not working. I guess it happened after upgrade to iOS 13 few months back. After I restart iPhone, sometimes these app work and all of a sudden iPhone restarts on its own and then these apps stop working. I am quite frustrated with this issue. Anyone guide please.
iPhone 8, iOS 14
