When you call NavigationUI.setupWithNavController(navigationView, navController), you're saying that you want NavController to handle click events from your NavigationView, navigating to the related screen as per the NavigationUI documentation. This, by necessity, calls setNavigationItemSelectedListener() internally.

By calling setNavigationItemSelectedListener afterwards, you remove the original listener, which is why your other items don't do anything anymore. You can trigger the default behavior by calling NavigationUI.onNavDestinationSelected()

@Override
public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {

    int id = menuItem.getItemId();
    if (id == R.id.callUs) {
        Intent intent = new Intent(Intent.ACTION_CALL);

        intent.setData(Uri.parse("tel:" + "XXXxxxXXX"));

        if (ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
            ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.CALL_PHONE},REQUEST_PHONE_CALL);
        }
        else
        {
            startActivity(intent);
        }
   }
   else
   {
       // Make your navController object final above
       // or call Navigation.findNavController() again here
       NavigationUI.onNavDestinationSelected(menuItem, navController);
   }
   drawer.closeDrawer(GravityCompat.START);
   return true;

}
