I can't remember if I ever tried this on the last (for Aura One) firmware, but I've found a bug with this firmware in PDFs.

I turn the PDF to be landscape. If I use the double tap method, the bug doesn't occur (but since it zooms too much or too little and then divides the screen into 4, which means to read one line, I have to slide back and forth, it is not much good for me). But if I zoom to a custom level, it treats the page as if it is still in portrait mode (if you look at the small diagram, it is showing the zoomed bit of page to be the wrong direction, compared to what it actually is, and is claiming that the whole page vertically is visible, which it is not), and there is no way to get to the top of the page (because it believes it is showing it already). Swiping up doesn't move you to the very top of the document (which is sometimes ok, if there is a title "bar"), swiping down seems to work, even though the "this is what's zoomed in box" is still portrait, it does move to the bottom of the page. But no matter how much I swipe up, it claims it is showing the top, but it isn't.

When I am testing it at the moment, it is landscape, zoomed to 175%, and I'm pretty sure it is a normal letter sized document with normal margins. I say this because in the past, I have chopped the margins off of documents so they were "pre-zoomed" on my kobo. I also tested at 225% zoomed, seems to be the same. Can't get to the top. I also tested it with an irregular document (without 4 even margins and a title "bar", only has page number at the top middle) and this does mean that I can't read the top of the document at all when zoomed in on landscape. I miss several lines of text.

Also weirdly, even when zoomed in, a tap would move to the next page, but if you want to go back, it is as before (swipe backwards, press black bar with arrow). This is not the case when double tapped in, in that case you have to zoom back out (or with Forma use the buttons) before you can get to the next page. I think maybe if I play with it, being able to turn the page without zooming out, might be good, but when I was trying to test this other issue, it was sure annoying.

If this has already been documented, sorry, I try to keep up and I don't recall seeing it.

Edit: actually even zoomed in (not using double tap), it turns pages both directions by tapping. And at the moment, I can't get the menu to come up, so I can't get out of the document ;-p I'll try a bit more, but I might have to resort to powering off.

Double Edit: Re: getting menu to show. I am an idiot. Because the menu comes up in the normal place, I was hitting the normal spot. But I of course needed to be hitting the side of the device (which is now the bottom in landscape).

See photos in next post to see the issue.
