Different checks for different apps?
The apps that I've gotten through the review process have been communications, and both Google and Apple have taken an interest in them. Apple rejected one based on the lack of a "beep" when the call was recorded, and another time they wanted a video showing the app being used. Google has always taken quite some time, many hours, for the app to work its way through their process. I've never seen a Google app be approved in minutes.
From all of the malware that's been springing up from the very first on the Google play store, I would have expected that some rather heavy analysis would have been instituted to put in some red flag checks. Apps that ask for administrator privileges should be marked with a big red flag. I'd really love to see a comparison of Google Bouncer to the "virus" scanners from the major AV players.
