But first, let me state I found no documentation so I'll spare you my thoughts about products with such.
If you go to settings>more tab>security>device administrators you may see a list of all administrators and maybe you need to add you to that list?
Sorry but this is a long shot. Maybe they are right.

LG Optimus F3 trying to get rid of the pin and go back to swipe In settings this option is greyed out and according to LG and my wireless carrier, I would have to restore the phone to factory settings to fix this. I am trying to avoid doing this, any help would be appreciated, thanks!
