Quick answer
EPUB and PDF for reading can be better for different kinds of content. Test them on the kind of reading you actually do.
EPUB usually lets text resize and reflow to fit the screen, while PDF keeps the original page layout.
For normal books
Flexible text and simple navigation often matter most for novels and essays.
For PDFs and fixed pages
Page fidelity, zoom, crop, and orientation matter more when layout carries meaning.
For study
Search, highlights, notes, bookmarks, and easy return points may matter more than visual style.
For listening
Voice quality, background playback, battery use, and keeping the active passage visible can change the decision.
If the first fix does not work
Try another known-good epub vs pdf for reading example. If the second one works, the first file or item is probably the problem. If both fail in the same way, the app, phone, or setting is more likely.
Detailed troubleshooting checklist
Work through the problem in this order: first check epub vs pdf for reading itself, then the app, then Android or the device. Keeping that order prevents you from changing many things when only one part is wrong.
