Feature description

There needs to be some indication of the level of magnetic field around the device. There are libraries supporting this feature that can be used. The indicator needs to be gracefully implemented in the design and should look part of the current design language.

Why do you want this feature?

Magnetic fields deflect the device compass and make them inaccurate. The user should be made aware if they are in the presence of a strong magnetic field, as it may cause them to follow a wrong direction for Qibla if they don't cross-verify with the map.
