Just took it for a spin. Interface looks decent. I love that I'm able to invert colors aka PDF dark mode cheat.

But I don't seem to be able to add annotations to a PDF and sync that back to my desktop, which is a bummer. I'm sure that will work in the future, and then I will finally be able to read and annotate papers on a tablet.

Okular set a high bar for what a good PDF Reader can do, this is surprisingly decent. The one killer feature which I don't anticipate any other software to implement any time soon is the "trim margins" feature of Okular, which makes pdfs so much more readable. For some.of those journals, the margins are like 30% of the width, that's some serious screen read estate, and the text is often too small already with academic papers.

Librera can automatically crop whitespace. And Adobe Reader has Fit Visible (Ctrl+3), which most of the time is good enough.

Well, for now I can't even figure out where Zotero stores the PDF locally on Android... Wish there was a button to open the PDF externally. I appreciate that there is a built in reader though.

I just noticed that the new Zotero has a double click to zoom feature, which does pretty much the same thing. It's great!
