Heating Issue in this phone is not because of the phone or processor .it is because of the Network

When i use mobile data in my phone it gets heat up from the upper part of screen and from camera cutout section, but when is switch my mobile data with WiFi, it doesn't heats!!!!

Try Turning off Mobile data and switching to WiFi (or Hotspot) and you will definitely see mind blowing difference between the temperature of your device!!!
