The Magnetometer
constructor creates a new Magnetometer
object which returns information about the magnetic field as detected by a deviceβs primary magnetometer sensor.
If a feature policy blocks use of a feature it is because your code is inconsistent with the policies set on your server. This is not something that would ever be shown to a user. See Feature-Policy
for implementation instructions.
