In Android, if we disable app notifications using the OS settings, will fcm/gcm still deliver the notification to the device? If it is delivered to the device will the notification be passed onto the app? or does the OS block it? Is the device_token invalidated? I am assuming that when we disable notifications, android os communicates these settings to the fcm/gcm server.

Are push notifications delivered to android phones after its disabled in settings?
