Using Droid Bionic, Kernel 4.0.4.
Out of nowhere my phone just prompted me to set up a Pin to unlock my phone. I set it up as I had no choice. I've gone in to settings/security & screen lock/screen lock only to see "none" is grayed out. It's not letting me remove the need to enter a Pin as I prefer.
Anyone have any ideas cuz I'm a novice and am stuck.
