You tap the app icon.
The screen doesn’t appear.
No splash screen.
No loading animation.
Then a notification arrives.
That’s the confusing part.
The app is clearly alive, but the screen never shows.
This situation usually means the app is allowed to run in the background, but blocked from opening its main interface.
In many cases, the system doesn’t treat this as a crash.
From the phone’s perspective, the app is “working.”
Notifications use a separate execution path.
They don’t require the full app UI to load.
That’s why alerts can appear even when the app itself feels completely dead.
This often happens after system permission changes, background limits, or security-related settings.
The app starts silently, completes a background task, sends a notification, and then stops.
No error message.
No visible failure.
Just silence—except for the notification.
To users, this feels broken.
To the system, everything looks normal.
That mismatch is what makes this issue so frustrating.
If notifications keep arriving but the app never opens, the problem is rarely the app itself.
It’s usually the system deciding what the app is allowed to show.
