A53 laggy after unlock with Touch ID

[Meekay]

I got an A53 literally 2 days ago but I am starting to realize a weird glitch in which after I unlock my phone, it's  laggy for maybe 5 seconds. It's not the Hz as I checked using the show refresh rate in the developer options. Does anyone know how to fix this? Although the issue is kinda small it's really annoying me as the phone is literally brand new and it's already starting to lag. 

EDIT: This problem only seems to appear when I am using touch id to unlock my phone. i have not tested it with pattern unlock, face unlock, or an unlock requiring no form of security.

I have the same issue. But suddenly I realize it only happens when the Extra Dim feature turned on. If you tured off the extra dim feature lock screen works perfectly.

Looks like Samsung isn't serious about resolving this issue. After after a year of A53 launch, touch iD lag issue hasn't been resolved. Worst thing about this phone followed by laggy exynos processor
