Forgive me for this stupid question. I just transitioned from iPhone to Pixel (GrapheneOS) and I’m curious why there isn’t a built in PDF viewer like on iPhone? It feels like you have to open things externally pretty often, but I figure there’s a reason for that. I haven’t used Android in many years and I recently developed an interest for the technical aspects of things, so again, do forgive this beginners question.
Cheers y’all!

Retail Android ships with Google’s proprietary PDF viewer. GrapheneOS isn’t the default experience.
GrapheneOS has an actively maintained PDF viewer app though.
It’s a secure PDF designed to sandbox the file before launching it, but unfortunately it’s painful to use: no page scrolling, and no dark content view…
Page scrolling works fine and dark mode doesn’t make sense…
Dark mode really starts to make sense when you’re looking at documents for 7-10 hrs/day almost every other day for a month or two
Easier to maintain and update when the reader is an app not part of the core OS.
Yeah but system apps can be updated separately from the main OS on Android, so that doesn’t really apply
Because… Fuck Adobe. This is my near-daily mantra.
You really should ask this in
http://discuss.grapheneos.org/
https://lemmy.ml/c/grapheneos.It’s a very helpful community. Someone will either explain why or point you to a FAQ. I bet it has something to do with the built in reader being insecure.
Edited… I totally gave the wrong url. Sorry. Corrected.
Hi there! Looks like you linked to a Lemmy community using a URL instead of its name, which doesn’t work well for people on different instances. Try fixing it like this: !grapheneos@lemmy.ml
Thanks for letting me know! (:
GrapheneOS actually has a built in PDF reader. Open the “Apps” app if it isn’t installed. Look for “PDF Reader” and make sure its installed.
My Android /e/os, a fork of lineage os, also has a built-in one.
So yeah OP, I guess the question is, why does your phone not have a built-in PDF reader, not why android doesn’t have one :D
I think I might be using the wrong terminology, forgive me. What I mean is, in my case, why does the PDF have to open in PDF reader instead of directly in the browser (like on iPhone)? That’s what I mean when I say “opening things externally.”
It doesn’t have to, but GrapheneOS is designed around security first, privacy second, and usability third
If you install Fennec browser on it and open, e.g., https://www.learningcontainer.com/download/sample-pdf-file-for-testing/?wpdmdl=1566&refresh=6697dcd62a0141721228502
The PDF will display inside Firefox
The default web browser on GrapheneOS, Vanadium, doesn’t parse PDF’s (they’re an incredibly insecure format) and passes them off to a sandboxed, hardened app specifically for that usecase
This allows rejecting more permissions than doing it in the same process
It doesn’t need to be opened with any specific app. Android lets you set default apps for different file types (this is determined by the ending file name characters after the “.”). Since you’re on GrapheneOS, you’re probably privacy-conscience and would be wise to stick with the app included with the OS. This behavior contrasts a user who heads to the Play Store and goes with any PDF reader willy-nilly.
I think it’s a fundamental design question. Apple wants users to do everything within their ecosystem, so they internalize as many functions as possible, whereas Android was designed to be lightweight and modular. Everything you don’t absolutely need in a browser just clutters it up.
Personally I like the flexibility of using exactly the app I want for functions rather than having my OS enforce a default.
A browser is also an app, it’s not embedded into an OS.
In some it comes preinstalled, which is the case for safari in ios.
Also, some browsers just happen to include a PDF reader, but not all had or currently have.As @viking@infosec.pub mentioned, Android is meant to be lightweight so it can run in several configurations of hardware.
Most OEM do include a browser in Android, this usually being Chrome. GrapheneOS is basically just Android (in this context) so it doesn’t include a browser or a PDF reader, but both are available as a dedicated app from the GrapheneOS team or with any other app you want, for example I use readera, or sometimes Firefox.
AOSP has no default PDF viewer, many GAAPS (official roms, custom roms with full gapps etc.) roms do have a pdf viewer by default.
There are many available PDF viewers around making a good pdf viewer is actually pretty hard, I reccomend just trying a bunch on fdroid and seeing what sticks out to you.
Firefox can open pdfs. If you prefer a browser does it
The good news is anyone can grab the GrapheneOS PDF viewer. https://github.com/GrapheneOS/PdfViewer Or from the Google Play store https://play.google.com/store/apps/details?id=app.grapheneos.pdfviewer.play
I have a built-in “PDF Viewer” app in my GrapheneOS. (
app.grapheneos.pdfviewer)I’m very interested in your reasons for switching, and I would love to read periodic updates on your experience.
You mean switching from iPhone to GOS? I can return to your comment after a while of using GOS to update you on my experience.
Thanks!
You could try their official app https://play.google.com/store/apps/details?id=com.adobe.reader
while many people hate it, it does work and has nice UI. Dark theme is my favourite.
