Phone getting hanged after screen unlock

[samin90]

I'm using a galaxy note 20ultra for last 2years

Recently whenever i unlock my screen via fingerprint

There comes a lag in transition from lock screen to home screen

The screen gets dark ,hangs for a second and gets me on the lock screen again

Today I've been facing another issue when the fingerprint scanner don't work though it was showing .

I locked the phone and tried 2nd time than the fingerprint worked

What's happening ?

Is this any software bug?

I've recently updated to one ui 5.1

Having the same problem on two devices. Problem it's the 2 year anniversary approaching when Samsung wants us to buy new phones.

It's interesting how those errors with no solutions comes up right after software updates...

If you have extra dim feature turned on, then turn it off.
My same problem was solved by doing this.
