Cannot swipe forward/back when viewing portrait document on landscape screen under "Fit width (single page)" rules

[lofidevops]

Steps to reproduce:

• Open a portrait PDF
• Turn tablet to landscape orientation
• Under settings select "Single page" navigation and "Fit width" zoom
• Swipe left / right

What should happen:

• Turn page previous / next

What happens instead:

• Nothing

Notes:

• This works as expected in when the tablet is in portrait orientation
• Can navigate to next page by scrolling down and pressing "hand" icon - no workaround to navigate to previous page

This is not a problem of portrait/landscape. And you seem to misunderstand the "hand" icon. The icon in the bottom right corner indicates, whether you are in the page-flip mode (where swiping left/right will change pages) or in the "hand" mode, where you can navigate around inside a (zoomed) page.

From my understanding, you cannot switch manually between these modes, but the first mode is always used, when the whole page fits on the screen (indicated by a double arrow in the bottom left corner). Otherwise the hand mode is used.

The "hand" icon itself does not have the purpose of pressing on it as you describe it. Instead the behaviour you describe seems to come from the standard tap areas, i.e. tapping in the bottom or top area will flip pages.

So your bug report is at first about communicating what I wrote in a more efficient way to the user. Whether we really want to implement some new swipe detection in "hand" mode, seems not so clear to me: Usually, tap configurations are meant to serve this purpose...

I understand and have tested the top/bottom tap behaviour, which works, thanks!

Perhaps an unobtrusive overlay on the tapping area would work? Probably easier said than done :) I'm leaving this ticket if you will be using it for any work on refinements / communicating details. If not, I'm happy to close it as my original request was resolved.

I hit a similar issue on a comic book with varying page sizes.

• Tablet in portrait orientation, the comic book was also portrait
• Document View mode: Single Page
• Page Fitting: Fit Width

Most of the time I had the <-> icon in the lower right corner, and I could flip pages by swiping left/right.

But some pages were taller than my tablet screen, and I got the hand icon in the lower right corner. On those pages the left/right swipe gesture no longer works.

Ideas to fix this:

• We could try recognizing swipe gestures to flip pages, even in "Hand" mode. I think there's a chance this will be annoying, since panning and the flipping gesture could conflict, but it's worth trying.
• Having page-flipping tap zones on the left/right side of the screen by default would also help. Other apps like Kindle do this.
