My new mount arrived last night and my Nexus connected to it flawlessly, at least in the house. I did a fake two star alignment and slewed all over the sky (actually living room).
The main difference I see is that the Windows App uses an AppBar button while the Android App uses a Menu Button. I noticed that the Android App does not have the following, Sync on Target, Alignment Tour, and Capture Target.
I do see a button in the settings screen that says USING FW OR IGNORE FW, and I am not sure what that is.
So using a Nexus 7 with no SD card and what appears to be total control, and no drop outs, so a very happy camper.
Thanks again to Pavel, for the correct file path.
