title: PhoneNumberUtil returns missing or invalid default region on a few devices
body: <p>I parse phone numbers from <code>String</code> representation via <code>com.google.i18n.phonenumbers.PhoneNumberUtil</code>> I faced with the issue </p>
  
  <blockquote>
    <p>INVALID_COUNTRY_CODE. Missing or invalid default region
    :</p>
  </blockquote>
  
  <ul>
  <li>phone number on Lollipop is parsed successfully and on KitKat (at least on some devices) the same phone number is parsed with <code>NumberParseException</code> </li>
  </ul>
  
  <p>It gives me a thought the issue can be in versions of library. </p>
  
  <p>Do you have any other ideas? </p>
