Samsung A12 wont lock...

[Android Central Question]

Hey all, so recently my phone won't lock after it charges. It will lock while it's charging but as soon as I take it off it won't lock any more. My phone will act like its locking and the screen will turn black for less then a second but then it comes back up on my lock screen. I have tried to leave it along to see if it would auto lock again on it's own but it will not. I have to reset it every day in order for it to lock properly. My smart lock is off my timers are set for a minute to lock but it just ignored that.

Welcome to Android Central! By "lock," are you just talking about the screen turning off after a certain amount of time? Do you have a case on?
