Lagging issue after upgrading to one ui 4 Note 20 ultra

[MimoRagib]

After upgrading to the latest one ui 4 my note 20 ultra has been super laggy. Specially when scrolling with less than 30% charge. In some games the touch response has been extremely terrible. It is almost unusable. This update is the worst update as far as I can recall. It is very disappointing from Samsung that we users r facing these kind of issues. I have heard that most of us are facing these kind of bugs. A major thumps down to Samsung.
