Quick answer
A good setup for reading books on a phone uses readable text or zoom, enough margin, a page color you can read clearly, and the movement style you prefer.
Start with defaults and change only what solves a problem.
Phone starting point
Use larger text for reflowable books. Reduce large margins. Keep portrait mode unless the page is wide.
Tablet starting point
Use comfortable line width instead of stretching text from edge to edge. For PDFs or comics, landscape and two-page views can be useful.
Save the setup only after testing
If your reader supports profiles, save a profile after a full session, not before.
