LG G3 :: Lock Screen Comes Up As White - Faint Images Of Home And Back At The Bottom

Just started happening today. When I turn my phone on, instead of getting the lock screen I get a white screen that just has the emergency call box at the bottom. I can get no further than this. When I touch emergency call, I can see the bar at the top with pending notifications, but no way to get there. I can hear the incoming text notification. I can receive a call. On the white screen, I can see the faint images of home and back at the bottom. I have rebooted, removed the battery. when I start in safe mode, I see the same white screen, but it does say safe mode at the bottom, but still can't do anything or get any further.
