I have a mobile phone running android. This one does not have SD card. I first installed panotour viewer without problem. I then created on my phone a PTV folder in which I copied my PTV file. This one is more than 3 GB. When I launch the viewer I try to recover the PTV file but it does not appear anywhere. Impossible to launch the visit. Can you tell me the procedure to follow so that finally I can visualize my visit? Thanks in advance.
