Some recent version of the Nextcloud App switched to using an integrated PDF viewer app (provided by Collabora, I think?) instead of the Document Viewer native to Android.
Unfortunately, the integrated viewer is very slow and clunky on my device, making the experience of quickly viewing a PDF very annoying, almost useless. Which is a shame, because it used to be very smooth.
I would prefer to continue using Document Viewer, which is my default PDF viewer on my phone, but there doesn’t seem to be a way to configure this - unless I missed something?
I’m using a Fairphone 4, running Android 13, with the Nextcloud App version 3.31.2.
No, I didn’t find it. Having read it, the information doesn’t apply. It’s written for FP5, which has Android 14. The described methods for changing file associations don’t work the same on Android 13.
Also, only the Nextcloud app suffers from this issue. It is using a built-in PDF viewer instead of the system default one, which I strongly dislike.
