Hi!
If it's iPhone, try cleaning the lightning slot by blowing into it (maybe buy a small lens blower). I do get occasional disconnects, but they go away for a period of time after cleaning.
I have just started to experience this after updating firmware to .100, has never happened before, I pressed RTH but nothing happened, app was disconnected and I had no info on phone screen (signals etc) closed app, reopened and all ok, but it keeps happening on every flight I do now !
