You tap the app.
It looks like it’s about to open.
Then it’s gone.
No error.
No warning.
Just an instant exit.
This usually happens at the exact moment the app checks its permissions.
Not when you use a feature.
Not after you log in.
Right at launch.
Many apps verify permissions as soon as they start.
Location, storage, camera, notifications.
If something in that check fails, the app never gets past the first second.
The screen doesn’t freeze.
The app doesn’t load halfway.
It simply shuts down before you see anything.
This often starts after a system update, a permission reset, or a manual change in settings.
The app expects a response.
Instead, it gets a block.
When that happens, the app treats it as a fatal state.
So it closes immediately.
From the user’s side, it feels random.
But underneath, the app never makes it past the permission check.
