First of all, you need to ensure that you phone is up and running. Now, update your Facebook app. For this, go to Google’s Play Store. Push the option button, and go to ‘My apps’.
Tap the Facebook, and push the Update option. Wait for the latest version to download. If you already have the latest version, this step is not necessary. Before going to Play Store, make sure that your internet is working properly.
Having downloaded the latest version of Facebook app, the job is very simple afterwards. Open the app, and push the ‘Options Menu’ to reach the Settings. These settings are only about the app, and do not make any impact on your device.
Here you will see a box right next to ‘Notifications’. Check the box, and it will start your notifications. The job is not over yet. Scroll down, and select the ‘Notification Ringtone’. There are a few others options as well, regarding the nature of the notifications.
Pick the notifications of your choice. Having done so, tap the Home button to get back to the Android home screen. Now, the app will surely notify you about the future happenings on Facebook.
