If you’re experiencing sound issues specifically with the Facebook app on your iPhone, there are a few tricks to help resolve this issue.
Unfortunately, some users have been experiencing sound issues with the speakers on the iPhone that limits the volume and stops notification sounds until users get an iMessage. The problem appears to be most likely the Facebook app.
First, you should make sure that the silent/loud toggle button on the side of the device is swiped to loud mode. If the toggle is showing an orange color, that means it’s on silent. Just swipe it to the other side and turn up the volume from the side button or from the side up menu.
Sometimes if apps aren’t up-to-date they can cause glitches. You’ll want to make sure you have the most up-to-date version of the app by going to the App Store and updating the Facebook app.
You can also try restarting your phone by holding both the home and lock screen buttons together until the screen goes blank, once the device is turned off it will automatically restart itself without removing any data or personal information. You can also try turning off the background app refresh by tapping on Settings > General Background App Refresh > Facebook > Off. If that doesn’t work you can try uninstalling and reinstalling the app.
If none of the tips above help, it’s best to visit an Apple Store for further assistance.
