Just wait for another update. Exynos has heating issue. You only have one option i.e to manage it by using less 5g , kill background apps. Keep brightness ideal etc.

It is balanced phone. Little more heat than other phones in this segment. Back camera is very good. Front camera is decent. Sound is very good. In 4g battery drain is good. But in 5g battery drains fast. So if you have Little more budget then better ...

Exynos is bad in thermals department

I already update , no such issue facing , little heat faced initially but now fine
