Samsung — I am complaining about samsung galaxy m21 2022 edition

Phone has heating issue. Whenever I do video call, phone gets heated and a message comes on the screen that close ur app otherwise phone will automatically close after 20 sec. After that I do not able to use any app till the phone cools down. If I use any app same messages are started to come. Very irritating and frustrating experience for me.
Plz replace the phone because it is not completed a single month after purchasing the phone.
