Prepare the page
Place the document on a flat, contrasting surface with even light. Avoid shadows across the page and hold your Android phone steady above it.
Scan with Fileio
Open the PDF scanner in Fileio and capture the document. Review the result, then save it as a PDF file on your device.
Organize the saved PDF
Give the PDF a clear filename, then use Fileio's folders, search, sorting, favorites, and recent files to find it later. Fileio does not claim OCR support; the scan is saved as a PDF document.
