Description
Which app is your issue for
Document Scanner
Version
Running latest Version from F-Droid. Every Scan has misaligned Characters. Document is searchable, but whenever one tries to select text in the generated PDF, it does not work as expected.
FairScan from F-Droid seems to work just perfect for with proper "Text Position".
The issue seems to bei relatively easy yo fix, since there is a Preview Button beforehand. Processing must include a function to align OCR with the actual document.
What platform are you using?

Research direction
Reproduce the issue on Android 16 by creating a searchable PDF and testing text selection against the scanned document. Trace the OCR-to-PDF text-position handling and compare the generated placement with the preview and the reported FairScan behavior. Done means text selection aligns with the visible document content across representative scans.
