Hey there, marlenegraphicvideo.
We understand that after an iOS update, you're no long able to hear incoming call notifications or other notifications as well. The steps in the following article might be helpful: Use notifications on your iPhone, iPad, and iPod touch
To get notifications, connect to a Wi-Fi or cellular network. If you still don't get notifications for a specific app, try these steps:
- Make sure that the app supports notifications. Go to Settings > Notifications, select the app, and make sure that Allow Notifications is on.
- If you have notifications turned on for an app but you're not receiving alerts, you might not have Banners selected. Go to Settings > Notifications, select the app, then select Banners.
- Make sure that you’re signed in to your Apple ID.
- Make sure that Do Not Disturb is off.
- If you’ve recently installed an app or restored from a backup, open the app to start getting notifications."
You'll also want to ensure your iPhone is updated, along with any updates available for installed apps:
- Update your iPhone, iPad, or iPod touch
- Update apps or use automatic downloads
Let us know how those steps go. Take care!
