Can I use my smartphone as a thermal camera?

Yes.

Can you trick a thermal camera?

A thick woolen blanket is a good variant to defeat the thermal imager. However, it is considered to be a quick temporary method of hiding infrared radiation. To block the heat, you just need to cover yourself with a blanket. Actually, the principle of hiding from a thermal imager is identical to a space blanket.

What can a thermal camera detect?

Thermal imaging systems generally detect a high body temperature accurately when used appropriately. They do not detect any other infection symptoms, and many people with COVID-19 can be contagious without a fever. Also, a high body temperature does not necessarily mean a person has a COVID-19 infection.
