One thing you could try is to get a new SharedPreference instance after committing and see what happens:

SharedPreferences pref = this.getSharedPreferences("test", MODE_PRIVATE);
String user = pref.getString("user", default_user);
if (user.equals(default_user)) {
    pref.edit().putString("user", "new_user").commit();
    SharedPreferences newPref = this.getSharedPreferences("test", MODE_PRIVATE);
    user = newPref.getString("user", default_user);
}

Your editor is committing a new preference map into disk, but it is possible that the old SharedPreference instance is not notified of the change.
