How do I fix notifications not showing on iPhone running iOS 18.0.4?

1. Start with the Basics:

• 
  
• Check Silent Mode: Flip the switch on the side of your iPhone. Orange showing? You’re on silent. Flip it off.
• 
  
• 
  
• Volume Check: Go to Settings > Sounds & Haptics, crank up that alert volume.
• 
  

2. Notification Settings (the real MVP):

• 
  
• Head to Settings > Notifications
• 
  
• 
  
• Pick an app that’s being shady (like Messages or Mail).
• 
  
• 
  
• Make sure:
• 
  
• 
  
• 
  
• Allow Notifications is toggled ON
  • 
    
• 
  
• Lock Screen, Notification Center, and Banners are all checked
  • 
    
• 
  
  • Sounds and Badges are enabled
• 
  
• 
  
• 
  
• 
  

3. Focus Mode / Do Not Disturb:

This one hides stuff like a sneaky ninja.

• 
  
• Go to Settings > Focus
• 
  
• 
  
• Check Do Not Disturb, Sleep, Work, etc.
• 
  
• 
  
• Disable anything that’s scheduled or accidentally enabled
• 
  
• 
  
• Under each Focus mode, tap Apps and People to make sure important stuff is allowed through
• 
  

4. App-Specific Glitches:

Sometimes apps just need a little tough love.

• 
  
• Open the app (like WhatsApp or Mail)
• 
  
• 
  
• Check its internal settings > notifications toggle
• 
  
• 
  
• Also: try deleting and reinstalling the app if it’s still misbehaving
• 
  

5. Background App Refresh:

Your phone might be trying to “save battery” at the worst possible time.

• 
  
• Settings > General > Background App Refresh
• 
  
• 
  
• Toggle it ON for essential apps
• 
  

6. Software Glitch? Reboot It:

The classic fix.

• 
  
• Hold volume up + side button → slide to power off
• 
  
• 
  
• Wait a few beats, then turn it back on
• 
  

7. Still Nothing? Reset Settings:

Let’s not burn it all down—just reset settings.

• 
  
• Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings
• 
  
• 
  
• Doesn’t delete data, just resets preferences
• 
  

8. Update Check:

You’re on 18.0.4, but hey—maybe 18.0.5 is already out?

• 
  
• Go to Settings > General > Software Update
• 
  

If you’ve run through this gauntlet and still nothing? Hit up Apple Support. Could be a hardware issue or a deeper iOS bug.

Check this, first.

Or Use and customize the Action button on iPhone - Apple Support (IN)

Then please check the following.

• Check your DND status - Settings > Focus [Do Not Disturb]; Use Focus on your iPhone, iPad, or iPod touch - Apple Support
