Noifications "clogged"

but both have a blank cmd string.

Ahh, I didn't see that from what you posted as the cmd string contents was cut out.

I assume the first is the incoming call notification and the 2nd is the missed call ?

Yes, I believe so. Probably incoming and reject I think

Could it be a combination of the phone and Gadgetbrige ?

I don't know... it seems unlikely it's related to the phone though. I'm a bit busy now with the KickStarter but I'll try and look into this later on
