nobody talk about why GrapheneOS built-in PDF viewer and can not be uninstall, that's no make sence, PDF viewer need to as a standlone applications, seriously in 2024, most browser can able to open PDF files, and usually most people have to from browser if want to download PDF, and also local PDF files can able to open through browser too, so please change PDF viewer to a standlone app pls.
(just my view, if is impossible please tell me how to uninstall PDF viewer, if is still impossible please tell me)

    See here:
    https://github.com/GrapheneOS/PdfViewer

    Simple Android PDF viewer based on pdf.js and content providers. The app doesn't require any permissions. The PDF stream is fed into the sandboxed WebView without giving it access to content or files. Content-Security-Policy is used to enforce that the JavaScript and styling properties within the WebView are entirely static content from the apk assets. It reuses the hardened Chromium rendering stack while only exposing a tiny subset of the attack surface compared to actual web content. The PDF rendering code itself is memory safe with dynamic code evaluation disabled, and even if an attacker did gain code execution by exploiting the underlying web rendering engine, they're within the Chromium renderer sandbox with no access to the network (unlike a browser), files, or other content.

      AlphaElwedritsch what, but it still not a reason about PDF viewer is a required option of GrapheneOS, as of now i never use PDF viewer, not everyone also need looking PDF document daily, i know the PDF viewer are very secure but its useless

          TheAwesomenESQ so, i just hope GrapheneOS can remove PDF viewer from built in apps, thats a good app, should be able to allow users install this app from store as well, are not be built in

            stockmaster if it bothers you so much, just disable it. The difference between disabling and uninstalling will be a few Mb of saved storage space. If you really want to get rid of it, you can uninstall it via ADB (although I highly recommend against that, since it might break some system components. You have been warned). As you can already see from other responses, it doesn't seem to bother other people nearly as much, so I highly doubt the devs will make it a standalone app when it server pretty much a built-in system function.

                stockmaster The GrapheneOS team has decided, as part of their security focus, to ship a hardened browser (Vanadium) and also a hardened PDF viewer. Obviously users can install other browsers if they choose to, and also other PDF viewers. But it seems unlikely that the GrapheneOS team will remove the hardened PDF viewer unless a strong rationale is provided.

                Can you provide examples of how it would be better for users if the GrapheneOS team decided to stop shipping the PDF viewer?

                    de0u and yes, because it's just there and despite its simplicity, I find it my go to PDF viewer and I don't feel like I am missing out on something (features).

                      Just to note, from what I understand, Vanadium cannot read PDF files, it opens the PDF viewer to read PDF files. So it would be a hit to functionality to remove it.

                      The real question is how come when I open a .PDF from my email in it, there is no option to search the document for keywords?

                        DeletedUser87 The difference between disabling and uninstalling will be a few Mb of saved storage space.

                        It won't free any space as system apps are allocated a certain amount of storage so there is no reason to uninstall.

                        That being said, I don't love the PDF viewer; it's not very convenient to tap an arrow key each time to scroll, or the inability to go to a certain page number or search for text. But it's a safe PDF viewer that doesn't support JavaScript (I believe so) and it gives me ease of mind.

                            DeletedUser87 Uninstalling system packages from profiles is completely unsupported, not something that should ever be done and will not save any storage space. Apps included with the OS are not in the data partition but rather part of the OS images and therefore do not use any space available for data. The overall amount of space reserved for the OS is fixed and only limits how much can be bundled into it. It does not make any difference to the available storage space.

                                GrapheneOS Thanks for the reply. Sometimes it's easy to forget the devs can't wave the magic wand and make every feature appear.

                                  yore the inability to go to a certain page number

                                  There is such a function, only it is very not obvious.
                                  Three dots --> "Jump to page" --> in the menu click on the open page number and enter the number manually from the keyboard.

                                  • yore replied to this.

                                      GrapheneOS so GrapheneOS also should be built in a VPN client, a Drive client, and more google shit alternatives right? if PDF viewer its here, why not Docx viewer, Xlsx viewer, PPT viewer? finally we can get a system that is built in so many useless system apps and can't to uninstall just only because its secure. Apple IOS allowed EU users delete system apps even Safari, Camera and App Store, i think GrapheneOS can do it better. i looked these reply and i know the PDF viewer as a standalone is impossible, i just hope PDF viewer can uninstall in settings, not everyone need looking PDF files daily

                                          stockmaster you are being very rude over a very trivial thing here buddy. This is the worst attitude to have in life, honestly.

                                          built in so many useless system apps and can't to uninstall just only because its secure

                                          That's how Android works. Apps are installed in a separate partition and can't be uninstalled when they are shipped as part of the "product" partition. You will find the same behavior on every single Android flavor. If it is useless for you, doesn't mean it's useless for other people. The phone app is also useless for me, maybe we should get rid of it too for all users then? How about the system DNS resolver, it's bloat, right? I think the right approach would be to ship the OS without any apps and let the user install them via adb. Doesn't that sound amazing?

                                          Apple IOS allowed EU users delete system apps even Safari, Camera and App Store

                                          The change hasn't even rolled out and there's no news on when it will. As far as I know you will only be able to uninstall Safari. I would love to know how you can reinstall the App Store once you delete it.

                                          i just hope PDF viewer can uninstall in settings, not everyone need looking PDF files daily

                                          I repeat: just disable it.

                                              DeletedUser87 calm down mate, no need to get upset over other if you can call it peoples ignorance, I have learned from my mistakes.

                                                DeletedUser161 Three dots --> "Jump to page"

                                                You're right! I had never seen that before :)
