Researchers build $200 robot to mash buttons and crack Android PINs | The Verge
Apparently this robot can crack the code to an Android device in under 20 hours. But, you will have to have a 4 digit code and not the include pattern lock.
The people behind the robot want to point ou how unsafe 4 digits are on a device like this. You can already max out you number of digit to 16 on android, but using just 2 more, would take the robot 2 months to crack you Android. So just think about those 6 digits, and do not make them a birthday.
