Expo Location watchHeadingAsync not working on Android

I am writing an app that requires me to track the heading of the user's device. Everything works fine on iOS, but on Android the heading is very unstable and flickers between 2 values very often:

Log output:
angle: 17.43
angle: 358.7
angle: 17.43
angle: 358.7

Here is my code:

    onVidLoad(){
        Location.watchHeadingAsync(this.onHeadingUpdate).then((v) => {
            this.ang_listener = v;
        });
    }

    onHeadingUpdate = (h) => {
        var angle = h.trueHeading;
        angle -= 180;
        angle *= -1;
        angle += 180;

        console.log("angle:", angle);
    }

Thanks in advance.

EDIT: I am using Location.requestForegroundPermissionsAsync every time the app starts, so the problem isn't that I don't have the correct permissions
