Yes, as I mentioned I have to use PIN because of my working email and it is set in Settings. But unfortunately there is another lock screen (probably from Sony) that cannot be disabled. And one more issue. When I wake my phone now and it´s still locked I cannot see any notification (unread emails, messages,... nothing) untill I unlock the phone. In my case it means go through 2 lock screens, one by swipe and the other one with pin. Pretty annoying.
