The new '+' buttonSeveral major changes in version 2.0 of Genius Scan for Android have made it easier to scan multi-page documents. The most important is the introduction of a '+' button which indicates that the next scan will be saved in the current document.
In short, use the Camera button to start a new document, and the '+' button to add pages to the current document.
Creating a Multi-page PDF DocumentTo scan the first page of your document, tap the Camera button as you're used to and follow the scanning process. When you're done, save this page to a new document using the Save button.
Edit the name of your document (or keep this for later if you're in a hurry) and tap the '+' button to add a page to this document. Keep tapping the '+' button to add more pages to the current document.
Once you are done, you have a multi-page PDF document at hand, ready to export.
Remember: all these features are available in the free version of Genius Scan. Happy scanning!
