  4. I’ve got issues with my one x heating up but I watched your video on the test you done and read the reply that you got from HTC… Do you know if that is a firmware issue that the phone is heating up like that and also my phone has randomly reset its self. Do you know what the issues might be cause I’ve heard that it might do that if the phone over heats
