After you upgrade your smartphone to One UI 3 and Android 11. Just do a "Factory reset" of your Galaxy S20 it'll help you get rid of most of the issues you're facing right after the update, as it'll provide you a fresh and a clean start .

For factory reset follow these steps:

1. Open settings
2. General management
3. Reset
4. Factory reset.

But do note, before performing factory reset of your device do keep a backup of all the necessary data, information and documents from your phone separately to a different device or else your data will be lost/cleared forever!

same problem

I've been beta tester, now I've updated to complete version. however, I've never faced any problem. i guess factory reset will fix any issues with the software.
