Missing notifications on a Galaxy almost always come from one of three places: a mode that silences them, the app's own switch, or battery limits that put the app to sleep. Samsung's own fix list checks them in this order.

The screenshots are from a Samsung Galaxy A57 5G with One UI 8.5 and Android 16. Other Galaxy phones on One UI 8 use the same menus; on older One UI versions a few names and positions differ.

Step by step

1. Turn off Do not disturb and Power saving

   Swipe down from the top right of the screen to open the quick panel. If Do not disturb or Power saving is highlighted, tap it to turn it off. Both can stop notifications from showing.

   Done

2. 

   Open Notifications

   Open Settings and tap Notifications.

   Done

3. 

   Check the app's switch

   Tap App notifications. Every app has a switch; the app must be switched on. For more options, open Settings, Apps, the app, Notifications, where Allow notifications must also be on.

   Done

4. 

   Check Do not disturb here too

   Back on the Notifications page, Do not disturb shows whether a schedule turns it on automatically, for example at night.

   Done

5. 

   Take the app out of sleep

   Open Settings, Battery, Background usage limits. If the app is listed under Sleeping apps or Deep sleeping apps, touch and hold it and tap Remove. For apps that must always deliver at once, such as a messenger, add them to Never auto sleeping apps.

   Done

Good to know

Some apps have their own notification settings inside the app as well. Check those after the phone's settings.

Put unused apps to sleep, on the same Background usage limits page, can move apps you rarely open into Sleeping apps on its own. If notifications from such an app stop, look there first.

For the battery side of the same settings: Samsung Galaxy battery draining fast? 6 fixes.

In short: Quick panel: Do not disturb and Power saving off. Settings, Notifications, App notifications: app switched on. Settings, Battery, Background usage limits: remove the app from Sleeping or Deep sleeping apps.
