- iOS and Android
- Scenario
- Reading and annotating PDF documents comfortably on mobile devices, especially in low-light environments.
- Observed behavior
- The current mobile application restricts or lacks support for dark mode and highlighting within dynamic reading modes like Liquid Mode, and colored highlighting is limited in standard dark mode.
Ensure your mobile PDF application is updated to the latest version, as developers frequently release new feature enhancements and UI updates for reading modes.

Frequently Asked Questions
Why is highlighting disabled in Liquid Mode on some PDF apps?
Dynamic reading modes reformat the underlying PDF structure on the fly to fit smaller mobile screens. Because the text is constantly reflowing rather than staying in a fixed position, precise anchor points for annotations like highlighting are technically difficult to maintain, which is why the feature is often restricted.
Does my iPhone's system Dark Mode automatically turn PDFs dark?
No. While the iOS system dark mode changes the application's menus and UI elements to a dark theme, the actual pages of a PDF usually remain white to preserve the document's original formatting. To make the pages dark, you must use a PDF reader app that features a dedicated document 'Dark Mode' or 'Night Mode'.
Can I change highlight colors in mobile PDF readers?
Yes, in most standard PDF viewing modes, you can change the highlight color. You typically do this by tapping on an existing highlight or long-pressing text, which brings up a contextual menu where you can select a different color palette. However, this functionality may be temporarily disabled if you are in a specialized text-reflow reading mode.
