How to use Anatomy 4D?

Question

Android

1. Installed Anatomy 4D on a tablet (android).
2. I printed a page with markers on a color printer.
3. I tried to twist the tablet this way and that, but it does not show anything.
I think the problem is in a bad camera and it does not see the markers. If someone tried to use this application, advise what should I do? Maybe it's not the camera...
