I presume this is very similar to what Google does in the kill switch. I am assuming that the kill switch is an application on my device, just hidden from me. When Google wants to remove an application, it silently uninstalls it without asking for our permission. I am very sure this security hole is of their making. Now we just need to figure that out... =D
