My daughter's phone screen has a gray lock screen

The mobile phone shows the fingerprint screen, if you swipe up on the remote screen that is grey with the lock and clock (eg. in photo above from bob) it will go to the pattern lock, but the remote phone will still show gray screen with the clock and lock moving around cut off like its a full screen tablet.. I cannot access the phone from here.

ALSO, once I log in from my Remote phone to the HOST, once the user logs in, the password unlock stops working until restart. Meaning if the host locks their phone, someone can just swipe up on the finger print and itll let them into the phone.
