I did a fresh update and factory reset to 7.1.2 and am jailbroken. Today I was in a call and hit 'contacts' and it says 'enter passcode' with the standard keyboard. I've never set a password on this or any phone I've ever had. I've tried multiple times and I cannot get into my contacts while on a phone call. If I search for a contact from the homescreen while on a phone call it asks for a passcode. If I open the contacts app from the homescreen while on a phone call it works fine. Help!
