When I use my phone on cellular, my phone gets really hot, and it is hot enough to burn my hand. Even, using personal hotspot warms my phone up more and more. When I was using it o Wi-Fi, there was not any problem with the temperature except in some cases (using it so long hours, taking photos more during the day)
