    a couple of days ago my phone (lg k20 plus) stopped unlocking using my pattern despite it being correct. after i draw my pattern, the screen goes black for a moment (sometimes it'll even flash my home screen a second) but then returns to what it looks like when locked. luckily i can use the fingerprint to get in. i've tried turning off the pattern unlock setting, but when i try to it asks for my pattern and then says "unfortunately, lock screen settings has stopped." i'm at a loss as to how to fix it

    Welcome to Android Central! Does it also happen in Safe Mode? https://support.t-mobile.com/docs/DOC-34011
