Why there is a notification regarding phone over heating during little long uses of camera function and stop working. It is very bad for a flagship mobile like this one. It's felt like cheated when someone has given his/her hard earned money and in return received this type of product. Very bad experience from Samsung.
This is because Samsung camera of S21 is not well optimized after the last update. So give your feedback to Samsung regarding the issue and wait for the next update
