That doesn't answer my question, I assume you use Cocoon.io or Phonegap?
Did you make exported, on device tests at all?
Well, I think it does that answer your question, if I understood correctly (I'm using translator to understand you).
Tests have been using preview over wifi, as I said before, then I have not exported to a apk and I have not done a test from an apk file.
