Android device tokens are not saved from all devices

I created an app with push notifications.
On my device it works like a charm. Im using Samsung galaxy 4.
My friend installed my app on his LG g3 and his user id appears in the users section in the ionic dashboard but the device registration token is not saved and remains empty so he cant recieve notifications…

What could be the problem and how can it be fixed?


Can you please post the code snippet where you’re generating the tokens?

This helps?

   .service('PushNotificationService', function( $ionicUser, $ionicPush, $rootScope, $http, $localStorage) {
     console.log("SERVICE: PushNotificationService");

  // Handles incoming device tokens
  $rootScope.$on('$cordovaPush:tokenReceived', function(event, data) {
    console.log("Successfully registered token " + data.token);

    // Save the registerID in the database
    $ "some url", {regId: data.token}).
      then(function(response) {
         console.log("Successfully registered token with the WEB SERVICE");
        // this callback will be called asynchronously
        // when the response is available

      }, function(response) {
        console.log("ERROR:   FAILED registering token with the WEB SERVICE");
        // called asynchronously if an error occurs
        // or server returns response with an error status.

var PushNotificationService = this;

PushNotificationService.identifyUser  = function(){
    var user = $ionicUser.get();
    if(!user.user_id) {
        // Set your user_id here, or generate a random one.
        user.user_id = $ionicUser.generateGUID();
        console.log("Generated user ID");

    // Add some metadata to your user object.
    angular.extend(user, {
        name: 'Application user',
        bio: 'Android app'

    // Identify your user with the Ionic User Service
       console.log('Identified user ' + + '\n ID ' + user.user_id);
       console.log("Calling the registration function");
        return true;

PushNotificationService.pushRegister = function(){
     console.log("Start of registration function");
    // Register with the Ionic Push service.  All parameters are optional.
        canShowAlert: true, //Can pushes show an alert on your screen?
        canPlaySound: true, //Can notifications play a sound?
        canRunActionsOnWake: true, //Can run actions outside the app,
        onNotification: function(notification) {
              console.log("Recieved notification");
               // Handle new push notifications here:
               switch( notification.event )
                       case 'message':
                             $rootScope.$broadcast('notification:updated', notification);                        

            return true;


Are any of the error callbacks firing in the console?

If he’s successfully able to send a post with his userID but not the token, is it possible your back-end is preventing write access to token?

No errors in the console…
My back-end is not preventing writing because it the whole thing works with some devices.

The problem is that SOME devices dont register an Android token id like in the picture i attached.

I have the exact same issue here, also on iOS devices. Push notifications work amazingly well on my device but on no other devices (Android or iOS) due to the fact the device tokens are not being registered. Would love to hear solutions if anyone has any :).

OHhhhh!!! Any one have a solution?

Same issue. I am using android - Sony Xperia Z. and the user gets registered but the token is empty.

same issue here, does somebody any solution???
