Anyways, on to my question. My mother and I both have Samsung Galaxy s3s with android 4.4.2, and I am able to set a new lock pin, change lock type, or even disable mine. She, however, cannot do so on her phone. I've looked myself, and it seems all other options for the lock screen are "grayed out" and unable to be selected. All we want to do is disable the lock screen on her phone. Anybody know why this is happening or what I can do to help her out?
