Weird bug after januari update A55

[Nootje]

So this glitch is kinda weird. For some reason the finger scanner is not doing thay weird light thighy when scanning my finger so I am unable to unlock my phone with my finger scanner. Also sometimes the top half of the screen just turns like a blue like colour on the lock screen. Am I the only one experiencing this or are there any others?
