Instead of using Obsidian PDF Viewer, it would be nice to use another application such as Firefox, Chrome, or Edge.
Proposed solution
Have a setting somewhere in the settings which lets the user set the default PDF viewer. When a user clicks on a PDF link/file, it’ll open in the desired PDF viewer.
After opening a PDF in Obsidian, you can use the “Open in default app” command to open it in your OS PDF viewer. The command is in the three-dot menu of the PDF pane, and also accessible via the Ctrl-P command palette. I have the command mapped to Ctrl-Shift-O so that I can quickly open files this way.
This maybe isn’t exactly what you’re looking for, but I hope it’s helpful.
Hi @jbcurtin, it looks like one of the moderators moved this thread to the “resolved help” category. I think you’ll need to open a new feature request specifically for this use case, maybe titled something like “Open file in default reader on mobile”.
By the way, I’m just a fellow user, not a moderator. The best I can do is give suggestions.
