Since upgrading to iOS 12, my iPhone 8 no longer makes a sound or displays a notification on my locked screen when I receive a text message. How do I fix this, or is this a bug in iOS 12?

Recently, there is the occasional feedback every now and then that the text messages and iMessage notifications are not working after the iOS system being upgraded to12. Have you ever encountered this kind of issue? We can imagine how annoyed it is to experience such notification problems, several important messages may be missed in some unintentional way. Here are the quick tips for the issue.

Tip 1. Receiving notifications but no sound

If your iPhone notification is working properly but not making a sound when receiving a message, you need to check whether you have set your iPhone in Silent mode. Take a glance at the Ring/Silent button on left side of iPhone, this button is used to mute sounds and alerts on your iPhone. If the switch is in orange, the iPhone will be set in silent mode, which means no sound for incoming calls, messages, etc. If you switch is not in orange color and the iPhone is still not making a sound after receiving a message, read on to find out the other fixes.

Tip 2. Turn Off Do Not Disturb

When the ‘Do Not Disturb’ is turned on, a moon icon will appear in the status bar. With Do Not Disturb feature, iPhone or iPad users will get alerts in a quiet way. It may be one of the reasons for iPhone text message sound not working. There are two ways to turn Do Not Disturb off:

  1. Head over to "Settings" > "Do Not Disturb" to turn it off.
  2. Swipe up from the button of the screen and tap moon icon.

Tip 3. Enable Allow Notifications

iPhone enables users to turn on or turn off notifications for specific apps. If the ‘Allow Notifications’ option for Messages app is disabled, there may be problems of not receiving message notifications. Go to Settings > Notifications > Messages to toggle on Allow Notifications. Then go to Settings > Sounds > Text Tones to set an alert sound. Restart your iPhone to check if iPhone can receive notifications.

Tip 4. Update DNS Servers

Update DNS Servers, for some reason, has worked well for several users. It is very easy to change DNS Servers from local ISP to Google’s Public DNS. Go to Settings > WIFI > Tap on Your Network Name > Configure DNS > Manual > Add Server to enter 8.8.8.8 and 8.8.4.4, then click on Save.

Tip 5. Turn on Recent Notifications

Some users left a feedback on Apple forum that enable "Recent Notifications" made messages alerts/notifications come through just fine. It sounds reasonable. When "Recent Notifications" is turned on, your device will receive alerts and notifications regardless of the device being locked or unlocked. To turn on ‘Recent Notifications’, go to Settings- Touch ID & Passcode, enter your passcode and toggle on ‘Recent Notifications’. It works a few times, you can have a try.

Tip 6. Reset All Settings

If the methods above are not working, try to reset all settings (Settings > General > Reset > Reset All Settings). It is unnecessary to worry about data loss. Reset all settings will not affect or erase the existing data on the device, it is just put the device settings to original settings. After resetting all settings, you have to re-enter passwords for wifi, touch ID, etc.
