I am yet to see Android vulnerability in the wild. This in India where everyone is on android and many using years old mobile. Compared to frequently viruses on windows machines. So are these devices hacked and the users do not know them? What area indications to know your device is hacked?
Perhaps it's like Linux on the playstation 2: During the time when sony enabled users to install Linux no one cracked the security. As soon as sony blocked linux, people cracked the security to restore it (and also copy the games...).
So long as the malware is coming from inside the playstore there isn't as much reason to exploit the vulnerable software...
