New Android viewer can show PDF folios.
But zoom is still missing?
Im i correct?
Pinch and zoom PDF works on Android.
The two finger pinch function (zoom) works on an android galaxy.
remember that it is only avaiable for non-smooth-scrolling pages.
I have tested PDf zooming on several (3) Android devices.
In my opinion it is very unstable. It depends even on screen orientation.
