compass heading is off by 40 degrees

[caleb87]

Problem

On a Samsung Galaxy S23 Ultra, the compass is about 40 degrees off. The compass shows 320 degrees when pointing north. It's off 40 degrees while pointing any directions. The Google Maps app shows the compass pointing in the correct direction, so I assume the phone operating system has the accurate compass?

What is expected to happen?

Compass heading is accurate.

What does actually happen?

Compass heading is not accurate.
