I just recently started using Zoho Notebook on an Android and tried scanning in documents for the first time today. It works fine with Evernote but is not working at all on Zoho Notebook. I go to capture, then document. I've tried it with and without using the icon to the right of the button for taking pictures to find borders. After it finds the borders something will spin on screen for a while but it ultimately stops. Sometimes it exits the program but usually just returns to the note list without adding the document. It does handle taking photos.
