Scanner flow rework - iOS and Android

[mpivchev]

General:

• 3 main steps:

  • Scanning
  • Reviewing & editing
    • Arranging
  • Saving

• Allow saving as PNG only if one image, otherwise allow only saving as PDF

iOS:

• Camera screen:

  • Add existing images/upload from gallery (dropbox)
  • Move "Save" button from camera screen to with the editing screens (where is the "Next" button is in dropbox)

• Remove image review screen

• Editing screen

  • "Apply to all" button for the filters

• Scanned images page

  • Do like dropbox
  • Show discard confirmation dialog

• Save screen

  • Do text recognition by default and hide the toggle
  • "Keep all scanned images" hide it and delete images by default
  • Rename can just be a dialog
  • Folder icon --> "Folder"
  • "/" --> All files
  • Remove "file creation"
  • Save button should be in the top right
  • Quality: Show the approximate file size in the in subline "(~500 KB)"
    

• More: remove scanned images, instead add a "Do you want to continue your previous scan?" when you click on scan document from +

Android:

• Update flow like Alper’s app (native implementation)
• Instead of PDF/PNG popup it can be a radio within the "Save" step: "Single document (pdf)" or "Multiple images (png)"
• Not possible to save to Nextcloud, only GDrive is visible in the Save dialog
• In scanned images, the save button should be more prominent
• No rename possible
