Notification not showing in samsung oreo devices

I encountered a strange problem today, push notification is not showing in samsung devices which have oreo in it but it's working fine in other oreo devices. Here is the code i am using:

 private void sendNotification(String messageTitle,String messageBody) {

        NotificationManager notificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        NotificationCompat.Builder notificationBuilder=null;
        try {
        Intent intent = new Intent(this, SplashActivity.class);

        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
                PendingIntent.FLAG_ONE_SHOT);
        String NOTIFICATION_CHANNEL="NB Shop Notification";
        Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.icon)
                .setContentTitle(messageTitle)
                .setContentText(messageBody)
                .setAutoCancel(true)
                .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.icon))
                .setSound(defaultSoundUri)
                .setChannelId(NOTIFICATION_CHANNEL)
                .setContentIntent(pendingIntent);


        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {

            /* Create or update. */
            NotificationChannel channel;
            channel=new NotificationChannel(NOTIFICATION_CHANNEL,
                    NOTIFICATION_CHANNEL,
                    NotificationManager.IMPORTANCE_DEFAULT);
            if (notificationManager != null) {
                notificationManager.createNotificationChannel(channel);
            }
        }
            notificationManager.notify((int) System.currentTimeMillis(), notificationBuilder.build());
        }catch (Exception e)
        {
            Log.d("sendNotification",e.toString());
        }
    }

It does not showing any error in log.

I found the issue which causing the problem, the constructor(NotificationCompat.Builder(this)) of NotificationCompat.Builder which has only single parameter is deprecated, To get rid of deprecation we have to send channel id with constructor, So i have changed my code and passed channel id to the constructor like this:

NotificationCompat.Builder(this,NOTIFICATION_CHANNEL)

also removed

.setChannelId(NOTIFICATION_CHANNEL)

and now this code is also working on samsung devices.
