title: React-Native: Get the same unique device ID after reinstalling the application
body: <p>I’m writing an app in React-Native and need some help concerning identifying the device after reinstalling the application.</p>
  
  <p>What I need:</p>
  
  <ul>
  <li>Get a unique device ID for every device for both Android and iOS.</li>
  <li>The same ID should be returned even if the user uninstalls the application and installs it again.</li>
  </ul>
  
  <p>The closest to this I’ve come over is the <code>getUniqueID()</code> method in <a href="https://github.com/rebeccahughes/react-native-device-info" rel="noreferrer">react-native-device-info</a>. However, a different ID will be returned on iOS if the app is reinstalled since the returned value for this method is related to the vendor.</p>
  
  <p>Have a great day!</p>
