Snapchat Notifications Not Working — How to Fix It

What Does This Error Mean?

Enable notifications in your phone settings: Settings → Snapchat → Notifications → Allow Notifications → On. Check that Do Not Disturb or Focus mode is not blocking Snapchat alerts. Enable Background App Refresh for Snapchat so it can check for new snaps while closed.

Affected Models

Snapchat on iOS
Snapchat on Android

Common Causes

Notification permission denied for Snapchat in device settings
Do Not Disturb, Focus, or Bedtime mode blocking Snapchat notifications
Background App Refresh disabled preventing Snapchat from updating while closed
Low Power Mode on iOS reducing background activity
Snapchat notification settings turned off within the app itself

How to Fix It

Enable notifications in phone settings

iPhone: Settings → Notifications → Snapchat → Allow Notifications → On. Also enable Banners, Sounds, and Badges. Android: Settings → Apps → Snapchat → Notifications → turn on All Notifications.
Check Do Not Disturb / Focus mode

iPhone: Control Centre → check if the moon or Focus icon is active. Swipe to turn it off, or add Snapchat as an allowed app in Focus → Allowed Apps. Android: notification shade → check if Do Not Disturb is enabled.
Enable Background App Refresh (iPhone)

Settings → General → Background App Refresh → Snapchat → On. Without this, Snapchat cannot receive push notifications when fully closed on iOS.
Check Snapchat's in-app notification settings

Snapchat → Settings → Notifications → make sure Snaps, Chats, Stories, and Friend suggestions are toggled on. The app has its own notification controls that override device settings.
Disable Battery Optimisation for Snapchat (Android)

Settings → Battery → Battery Optimisation → find Snapchat → select 'Don't Optimise'. Android's battery saver aggressively kills background apps including Snapchat's notification service.

When to Call a Professional

Notification issues are always a device settings or app settings issue. No account action is needed.

Frequently Asked Questions

Snapchat notifications delayed by hours — why?

Delayed notifications are almost always caused by Background App Refresh being off (iPhone) or battery optimisation killing the app (Android). Enable Background App Refresh on iPhone and disable battery optimisation on Android.

Snapchat notifications work on Wi-Fi but not mobile data — why?

Push notifications route through Apple or Google's push servers — if mobile data is restricted for Snapchat, notifications fail. Android: Settings → Apps → Snapchat → Mobile data → enable Background data.

Snapchat badge count shows unread but no notification — why?

Badge count updates even when notifications are muted. Open Snapchat to clear the badge. If you want audible alerts, ensure Snapchat has Sound enabled in your notification settings.
