For those who use PIN as the ultimate Unlock method, there is a feature "Confirm Pin without tapping OK". Its very useful to easily get unlocked, saving an unwanted screen tap. I would like to pointout a small security issue here.
The number of digits present in our PIN is also a factor of security and privacy. At present, it is easy for anyone to get the number of digits present in our PIN. Simply input a wrong PIN and after the specified digits it shows "Incorrect PIN entered" (without tapping OK). That may make his guessing easy, and also gives a hint about the correct PIN right?
