The eight - megapixel rear camera is perfectly adequate for general photography, with a decent flash and good macro functionality, so you can use it as
a pocket document scanner with the Office Lens app.
A Microsoft Garage project, OfficeLens turns your Windows phone's camera into a
pocket scanner, capturing
documents, receipts and whiteboard notes, cleaning them up and automatically transforming them into Office
documents, PowerPoint files, or PDFs which you can upload to OneDrive.
