Note20 lags badly in simple game

[Soo81]

My note20 lags badly in A3. Its not even a high graphic game and Samsungnote20 could not handle it. I have my old plus 10 Samsung running well. Paying so much for a 2nd phone note20 which don't function well at all. Such a disappointment. And I did not even download much app in this new phone.
