Quick answer
For long sessions, keep high-contrast reading moderate and stable. The goal is to reduce repeated eye and hand work, not to make the page look unusual.
Extremely bright combinations can still feel harsh in a dark room.
Use a stable page
Choose text size, spacing, margins, and page color before the session starts.
Avoid changing the interface every few minutes unless something is clearly uncomfortable.
Reduce unnecessary movement
Use paged reading if clear stops help you. Use continuous scroll if page turns interrupt you.
If motion bothers you, reduce animation where the reader allows it.
Take normal breaks
Long reading does not require staring at the screen without stopping. Pause when you need to.
A comfortable layout helps, but it does not replace normal rest.
Review after the session
If you often lose your place or keep zooming, change one setting before the next session.
Keep the change only if it solves that specific problem.
Detailed troubleshooting checklist
Work through the problem in this order: first check high-contrast 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.
