I have a phone with a thermal imager too!

As a bonus, my phone also has a microscope, and I learned that my facial hair is sometimes triangular:
Just because nobody asked:
Looking for a phone with this, a Geiger counter, and a light spectrum analyzer
Also a hardware keyboard, headphone jack, and runs Linux
It also needs to be under $50
Pixel8 has a thermometer built in.
