Setting up my phone and I wanted to establish the fingerprint scanner to use with PayPal. However, after registering my fingerprint, my phone was now set to unlock using the fingerprint scanner. Not a big deal but when I went into my lock screen settings to change my unlock settings (I don't use anything other than the Swipe), I noticed that the Swipe and None options were disabled. How do I change that? Do I need to delete my registered fingerprint?
