Description

Which app is your issue for

Document Scanner

Version

1.14.3.119

What platform are you using?

Android

OS Version

Android 15

What happened?

When scanning documents that are stapled by the corner (such as a top-left or top-right corner staple), the scanner fails to detect the page correctly when it is turned over. Specifically, when the page is flipped over to scan the reverse side, one corner of the document is "missing" from the scanner’s detection area, leading to incomplete scans.

Research direction

No files, tests, or code entry points are named. Reproduce the issue in Document Scanner 1.14.3.119 on Android 15 with a corner-stapled page, then trace the document-detection path; done means both front and reverse sides are detected completely for top-left and top-right staples.
