If your iPhone 11 suddenly stopped showing notifications right after updating to iOS 13.3, you’re not alone. It’s a common glitch that’s been bugging a lot of users — missed calls, messages, and alerts just not showing up. Here’s a full list of fixes you can try to get your notifications working normally again.
1. Make Sure Notifications Are Enabled
Sometimes the update can mess with your settings. Double-check if notifications are still turned on for the apps you’re missing alerts from.
- Go to Settings > Notifications
- Select the app (like Messages or Mail)
- Turn on Allow Notifications
- Make sure Alerts are enabled for Lock Screen, Notification Center, and Banners
2. Turn Off Do Not Disturb
Do Not Disturb silences all notifications, and iOS updates sometimes re-enable it without you noticing.
- Go to Settings > Do Not Disturb
- Make sure it’s turned off
- Also check if Scheduled is enabled — if so, it might be silencing notifications during certain times
3. Disable Silent Mode
It sounds obvious, but many users accidentally flip the Ring/Silent switch on the side of the phone.
- Make sure the Ring/Silent switch (on the left side of your iPhone) isn’t set to silent (orange showing = silent mode)
- Also try turning the volume all the way up
4. Restart Your iPhone
A simple restart can fix temporary software bugs that cropped up after the update.
- Press and hold the Side button and either Volume button until the power slider appears
- Slide to power off
- Wait a few seconds, then turn your iPhone back on
5. Check App Notification Settings
Some apps (like WhatsApp or Gmail) have their own notification settings within the app.
- Open the app where you’re missing notifications
- Go to its Settings > Notifications
- Make sure alerts, badges, and sounds are turned on
6. Reset All Settings
If nothing’s worked so far, resetting all settings might clear up whatever glitch is blocking notifications. This won’t delete your data, just your custom settings.
- Go to Settings > General > Transfer or Reset iPhone > Reset
- Tap Reset All Settings
- Enter your passcode and confirm
7. Update to the Latest iOS Version
If this is a known iOS 13.3 bug, Apple may have already fixed it in a newer update.
- Go to Settings > General > Software Update
- If an update is available, download and install it
8. Contact Apple Support
Still not getting notifications? It might be a deeper software issue. Reach out to Apple Support or book a Genius Bar appointment. Be sure to explain that this started after updating to iOS 13.3.
