import android.content.DialogInterface.OnClickListener;
import android.content.Intent;
import android.location.Location;
import android.location.LocationListener;

public class Main extends Activity {
TextView tvStatus;
LocationManager lm;
boolean gpsEnabled;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    tvStatus = (TextView) findViewById(R.id.textView1);

    lm = (LocationManager) getSystemService(LOCATION_SERVICE);
    if (lm.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
        Log.d("", "GPS is Active");
        Location l = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);
        tvStatus.setText(l.getLatitude()+" , "+l.getLongitude());
        lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0,
                new LocationListener() {

                    @Override
                    public void onStatusChanged(String arg0, int arg1,

Samsung phones have this problem. There is hack to this. You need to kick the locationmanager on the butt to get the latest location from the maps cache.

God.locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0,
            new LocationListener() {
                @Override
                public void onStatusChanged(String provider, int status, Bundle extras) {
                }

                @Override
                public void onProviderEnabled(String provider) {
                }

                @Override
                public void onProviderDisabled(String provider) {
                }

                @Override
                public void onLocationChanged(final Location location) {
                }
            });
    currentLocation = God.locationManager
            .getLastKnownLocation(LocationManager.NETWORK_PROVIDER);

Call getLastKnownLocation after kicking the requestLocationUpdates with 0's.
