How can I read PDFs in scrolling mode on an iPad 2? I bought a used iPad 2, mainly for reading. After a short while I found out that it won't run a more recent iOS than 9.3.5 and that there are basically no apps that run on this iOS version (rendering the iPad 2 almost unuseable--I really couldn't believe it). I have been able to open PDFs with the iBooks app that came with it, but I don't like the way you have to swipe from right to left on the screen to get to the next page. Is there either a way to switch to a &quot;scrolling&quot; behaviour in iBooks, where you can just swipe up and down on the screen to move seamlessly between pages, or a PDF viewer app that supports this and can still be installed on iOS 9.3.5?
This may be a solution - please give feedback so I can correct.
Login with the same appleid on a more modern apple device (iphone etc) or possibly on a desktop computer.
Purchase (for zero dollars) the apps &quot;USB disk&quot; with the purple logo and  &quot;Adobe Acrobat&quot;.
On the ipad 2, open App Store and either look at &quot;Purchased Apps&quot; or browse to find the identical apps you already &quot;bought&quot;, and download them.
The option to download an older version should appear.
The abovementioned apps have a version that works under 9.3.5 on ipad 2, open .pdf and use vertical scrolling. I just checked!
I also recommend you get the Chrome browser at the same time as some websites will work with it when Safari will not, and its availability may be terminated...
