PDF Viewer Pro Customer Insights

1. Experienced rendering glitches whenever I'd reopen the app, and it hides certain offline-useful features (like volume button navigation) behind their subscription service - no, sorry, I'm not paying a subscription fee to be able to use the buttons on my device, I reserve that approach for ongoing services.Works very well with focused set of features.

2. Viewing a pdf launches a separate app window, and the original window launch point changes, returning to a home view...huh? Back up from there and app exits...gah. "Recent documents" is always empty.My search for a free pdf viewer is over!! I needed a viewer for reading books.

3. The features are pretty good, but as far as I'm concerned, the app is worthless if it can't be trusted.Love the new ui but the latency is still too terrible to use!!!//Too bad that I can't reach the team via email, saying their email address is not available to receive incoming emails.

4. Search supports global find in the document and notes (excludes bookmark names).

5. I haven't really used any features except basic pdf files viewing and searching through them, as I don't really need them.

6. // The writing latency with S Pen is awful.Finally a PDF viewer that honours reading direction when scrolling right to left.

7. PDF Viewer Pro wins by a mile!A good pdf annotating app is surprisingly hard to find.

8. The recently viewed and general menu is easy to navigate, though sometimes for longer files it flashes in and out and takes a moment for the pdf to display.

9. It would be nice if there was a setting for use with the S-pen (or other stylus) so I could use my finger to scroll without having to turn off the annotation option first.

10. It has the mark-up features I want & works smoothly on my device (Samsung Galaxy Tab S7).

11. Excellent viewer.No problems so far (have been using for about a month).
