If your iPhone 7 Plus stopped showing notifications after updating to iOS 11, you’re not alone. Whether it’s email alerts, app badges, or text message previews that have disappeared, this issue is a frustrating one — especially if you rely on your phone to stay on top of messages, reminders, or business updates.
Here’s how to troubleshoot and fix notification problems on your iPhone 7 Plus after a system update.
1. Restart Your iPhone
A simple reboot often fixes minor post-update glitches.
- Press and hold the Power (Side) button until “slide to power off” appears
- Drag the slider to turn off the phone
- Wait 30 seconds, then press the Power button again to restart
Once it’s back on, test if notifications are working.
2. Check Notification Settings
Make sure notifications are actually turned on for the apps you’re missing alerts from.
- Go to Settings > Notifications
- Tap on an app (e.g., Mail, Messages)
- Make sure Allow Notifications is toggled ON
- Enable Lock Screen, Notification Center, and Banners
- Also toggle Sounds and Badges ON if you want them
Repeat this for all important apps.
3. Clear All Notifications
A backlog of old or stuck notifications may prevent new ones from coming through.
- Swipe down from the top of your screen
- Tap and hold the X, then tap Clear All Notifications
Now wait to see if new notifications appear as they should.
4. Disable Do Not Disturb (DND)
Do Not Disturb blocks all alerts when active.
- Go to Settings > Do Not Disturb
- Make sure Manual and Scheduled toggles are OFF
- Or swipe up for Control Center and make sure the crescent moon icon is not active
5. Reset Network Settings
Notifications tied to data usage like emails or messaging apps won’t arrive without a stable connection.
- Go to Settings > General > Transfer or Reset iPhone > Reset
- Tap Reset Network Settings
- Enter your passcode and confirm
This will erase saved Wi-Fi passwords and refresh all connectivity settings.
6. Restore Your iPhone via iTunes (If All Else Fails)
If the update broke notification delivery across all apps, a restore might be the cleanest fix.
- Backup your iPhone first (via iCloud or iTunes)
- Open iTunes on your computer
- Connect your iPhone and click the device icon
- Under Summary, click Restore iPhone
- Follow the prompts to reinstall iOS
- After restoring, re-enable notifications manually in Settings
⚠️ Note: This erases your device. Make sure to back up your data first.
7. Wait for Apple’s Fix or Contact Support
If the issue began after a specific iOS version, it’s likely tied to a software bug. You can:
- Check for updates via Settings > General > Software Update
- Contact Apple Support or visit a Genius Bar for a diagnostic
