You tap the app icon.
The screen doesn’t open.
At first, it feels like nothing happened.
Then you notice something odd.
The app briefly appears in the app switcher.
Your phone shows activity.
Battery usage updates.
So the app is running.
It’s just not allowed to appear on screen.
This usually happens when background processes are permitted, but the foreground launch is blocked.
The app starts, stays active, and then gets pushed out of view.
From the user’s perspective, this is confusing.
The app isn’t crashing.
It isn’t closing.
It simply refuses to show itself.
This feels different from apps that never start at all.
And it’s not the same as apps that open and immediately close.
Here, the app is alive.
It’s just stuck behind the screen.
