The new update did something similar to my phone. Now I have to Swype before I can attempt to unlock despite the fact that I have the fingerprint option set up. Also, for some reason one of the symbols on the first lock screen (so stupid) is on what appears to be Korean??? Wtf?! How do I fix this. I don't want this stupid extra lock screen. I'm attaching picture of the first lock screen. The symbol I don't recognize is right after the "5"
It's Chinese I think. 月 means "month", 달 is Korean for "month". Have you installed or updated any "free" adware apps recently, like anything by GO, such as GO SMS, GO Keyboard, etc.? Because those can put useless extra lock-screens in.
