on the phones the temp is what a weather service says (and thats based off of their nearest weather stations) not a sensor in the phone. They cant put a out side temp sensor in a phone as the phone will read hotter because the phone is warmer. than ambient temp. out of my 3 GMs with temp sensors all have been spot on. I have a $40 thermal gun but its 10 degrees off so unless its a very expensive one I wouldn't trust it to be that accurate. Like i said find a bank or even better a school that has a temp sign. Our school use to have a weather station for the local news at it but not anymore. of course a thermometer reading will work too if you know someone with one
