📦 Android App What makes a good Android PDF reader for long documents?

[Jsp666]

I’m looking for recommendations for an Android app that can handle large PDF files smoothly.

The features I care about are:

• Smooth scrolling
• Low battery usage
• Bookmarks or reading position
• Night mode
• Minimal ads

I mainly read long articles, manuals and ebooks on my phone. Which PDF reader has worked well for you, and what do you like about it?
