Lag after the software update to One UI 4.0

[Mannarkrishna]

I've noticed lags after the one UI 4.0 update today in India on my phone. It lags especially during the multi tasking ie switching between the apps 

There are animation frame drops 

Fingerprint scanner has once again become very slow in recognition of the finger 

If anyone else is facing the same issue please let me know
