I just tested saving https://browse.arxiv.org/html/2312.12451v1 to disk using Chrome, transferring it to my Android phone, and opening it on the phone. Results:

1. Saving as "Webpage, Single File" (.mhtml): Neither Firefox nor Chrome even showed up in the list of available apps to open it.

2. Saving as "Webpage, Complete": Opened in Chrome but images were broken. Also very difficult to open with the default file browser because it uses a flat folder view and the sidecar folder pollutes the file list.

I was hoping this would work, perhaps you will have different findings. I agree that HTML is the superior format in theory but usability in practice is often lacking. I'm resigned to using both depending on context.

Yes, that's the kind of issue I was talking about. I wish it were otherwise. As a nearby comment pointed out, epub is a potential solution (and I wish arXiv embraced it - without my knowing their other requirements or epub's accessibility features). It's essentially packaged html.

Of course, they’re “just text files” only in theory… but theory and practice diverge very very often.
