I have received my Galaxy S21 two days age, Since there I have to make my video calls or playing Call of Duty on my old Note 9!! It gets as warm as hell that you can not even use it! I will wait until the next week for an update ... Otherwise, I will send it back... No one wants a FLAGSHIP like this!! Because it is an issue that you can realize it DEFINITELY before realising a FLAGSHIP phone!! But you did it!! I was a real and loyal fan of Samsung phones, but now I am thinking about other good brands showing more respect to buyers choice!
They should not release the phone if it has some serious issues which can affect the user experience!
