I have just installed the Android Beta lastest versoin on Galaxy Note with OTG and Asus Transformer with dock, both on ICS. When I plugged my Nikon D3s into the Android device, it has a popup message which asking me if using Helicon Remote as default action (I tried both of MTP/PTP mode), I click Yes, and HRemote has recognized my D3s is connected, but I can't do anything with it, even the LiveView has not start, not work for all buttons. But when I changed the camera to Canon 5D II, it works fine with 100% function.
I'm really interested on HRemote as my Studio tethering, hope will be fixed asap.
