Enabling Accessibility Service for apps impacts encryption security as you can see:
Why is this?
I am all the more curious in case of PIN : my understanding is that, encryption password is generated from a combination of user lock screen PIN and encryption algorithm. This is salted, and stored in root location, and used to generate the actual password to encrypt /decrypt. So using a longer PIN length (to maximum of 16 digits ) is pointless if you have enabled Accessibility Service for any app?? Confused
