I just did an update on my Galaxy S3 and now it is required that I have a lock on my lock screen. Before the update, I had the simple "Swipe to Unlock."
Now, when I go into Settings>Lock screen>screen lock, I am unable to select the swipe option. It says "turned off by administrator, encryption policy or credential storage."
Does any one know how to disable any of those so that I can go back to my swipe lock screen? It is really annoying having to type a dumb password in every time i want to get into my phone.
