I am using PIN security for unlocking the phone. When i type the PIN, a blue highlight comes to the pressed digit. How can i hide it? I am in Note 2 rooted with stock rom.
Unfortunately there is no such function on Android. There is something similar when using a pattern to unlock your phone. Another solution would be third party software.
