FusedLocationProviderClient: Position frequency

Question

I'm trying to get a good position via android and GNSS. The locationManager of Android gives me in every Case only one update per second. So i decided to switch to the GoogleFusedApi and the FusedLocationProviderClient to get my current position more often.

---

I tried different use cases and had different results:

Going down the street:

Update between 200ms and 1000ms => Average: 450ms

---

Driving same route with the bike:

Update between 300ms and 1000ms BUT Average: 840ms

---

I don't get why i get less updates if my speed is much higher. In both cases the smartphone was in my pocket.

The important snippet of my code:

    private FusedLocationProviderClient mFusedLocationClient;
    private LocationRequest locationRequest;
    private LocationCallback locationCallback;

    mFusedLocationClient = LocationServices.getFusedLocationProviderClient(this);

    locationRequest = new LocationRequest.Builder(Priority.PRIORITY_HIGH_ACCURACY, 0)
                .setWaitForAccurateLocation(false)
                .setMinUpdateIntervalMillis(0)
                .setMaxUpdateDelayMillis(0)
                .build();

    locationCallback = new LocationCallback() {
            @Override
            public void onLocationResult(LocationResult locationResult) {
                if (locationResult == null) {
                    return;
                }
                location = locationResult.getLastLocation();
            }
     };

    private void getLocation() {
        if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
         
        }
        mFusedLocationClient.requestLocationUpdates(locationRequest, locationCallback, null);
    }

Maybe i did something wrong with the locationRequestSetup or something else? I hope anyone could help me to get the updates on Bike as fast as while walking.. Or could explain why i get the position more often while walking..

Is there any other soloution to get the Position with an average about 500ms in Android?

THANKS FOR HELPING!
