Location keep changing even if the device is not moving

I am getting current Lats and Longs using FusedLocationProviderClient and I am using the below code to get current lats and longs of the device:

public class FusedGpsService extends Service {


private FusedLocationProviderClient fusedLocationProviderClient;
private double speed;
Data datas;
List<Location> locationList;


@Override
public void onCreate() {
    super.onCreate();

    fusedLocationProviderClient= LocationServices.getFusedLocationProviderClient(this);
    requestLocations();

    Log.i("STATR","Started");
}

@SuppressLint("MissingPermission")
private void requestLocations() {

    LocationRequest locationRequest=new LocationRequest();
    locationRequest.setInterval(1000);
    locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);

    fusedLocationProviderClient.requestLocationUpdates(locationRequest,locationCallback, Looper.myLooper());




}

LocationCallback locationCallback=new LocationCallback(){
    @Override
    public void onLocationResult(LocationResult locationResult) {
        super.onLocationResult(locationResult);

        datas=MainActivity.getData();




        locationList = locationResult.getLocations();

        if (locationList.size()>0){
            Location location =locationList.get(locationList.size() -1);

            double lat = location.getLatitude();
            double lon = location.getLongitude();

            Log.i("LATLONG", "Lat: "+String.valueOf(lat)+","+"Long: "+String.valueOf(lon));

            //speed = (double) ((location.getSpeed() * 3600)/1000);
            //datas.setCurrSpeed(speed);
            datas.update();

            //Log.i("SPIIID", String.valueOf(speed)+ "km/h");

        }
    }
};

@Override
public void onDestroy() {
    super.onDestroy();
    if (fusedLocationProviderClient!=null){
        fusedLocationProviderClient.removeLocationUpdates(locationCallback);


    }
}




@Nullable
@Override
public IBinder onBind(Intent intent) {
    return null;
}

}

Everything seems to be good but if I stand still and I'm not moving the onLocationChanged() method still gets called and keep updating it into different Lats and Longs.

Are there any solution for this.

FusedLocationProviderClient does not give accurate value, use Location Manager and check accuracy of location by location.getAccuracy() and use location with accuracy less than 20.
