Currently, I’m just using the default ‘Drive PDF Viewer’ on my Android devices, would love to switch to something FOSS and non-google. Any good recommendations?
If it’s available on F-Droid, that would be preferable.
I am using Librera Reader. Make sure to install the F-Droid version (Librera FD) without Google Play services.
It is primarily an ebook reader that supports a variety of formats, but it is also an excellent PDF viewer. Significantly more feature-rich than any other FOSS PDF viewer for Android that I have found.
https://github.com/GrapheneOS/PdfViewer I’m using GrapehneOS and the integrated PDF viewer. Can’t say of it works flawlessly on other Android OSes, but you could give it a try!
MuPDF Viewer works fine for me. Not very feature rich tho.
Mupdf: lightweight, works great.
MuPDF comes by default on CalyxOS, and is what I use.
MuPDF mini or Sav PDF viewer
I recommend the GrapheneOS Secure PDF Viewer. Unfortunately it’s not on F-Droid, but you can use Obtanium to pull the apk from their GitHub: https://github.com/GrapheneOS/PdfViewer
MuPDF is another option, it even is available on F-Droid.
Mupdf or fossify file manager has a pdf reader built in
I normally use muPDF
Firefox Mobile can open PDFs fine - https://lemmy.blahaj.zone/pictrs/image/1c51814a-c761-4325-baa1-346e8ae2e7fb.png
I use MuPDF but there is also the GrapheneOS PDF viewer available on their GitHub
https://github.com/GrapheneOS/PdfViewer
You can install it using Obtainium or jus grab it from the GitHub page.
KOreader is great, but use muPDF if you don’t want to learn

Supports dark mode too
