Another scenario involves a more descriptive error, like “File is corrupted and cannot be opened.” You might also see a message indicating “No application can open this file” if no suitable PDF reader is installed or properly associated with PDF files. The loading bar might stall, never reaching completion, with the PDF reader seemingly frozen. The screen could also display a blank page with a small error icon in the corner.

In extreme cases, the entire PDF reader app might crash, forcing you back to your home screen with a system notification reporting the app has stopped working. Each of these scenarios paints a picture of digital frustration, signaling a problem that needs immediate attention.
