ESP32 Thing Plus AnalogRead

Development Boards ESP32

Hey, I have an ESP32 Thing Plus and I am inputting a voltage and trying to read it via analogRead(port#). It works as expected on pins 34, 39, and 36. On pins 26, 25, or any other for that matter, I just get 4095 or 0. Is there something I need to do to set the pins as analog? What am I doing wrong?

Thanks,

Dan

Can you send a picture of your setup?

I can but I guess the real question is. Is there anything in code I have to do to make input 25 act like input 34? Same analog voltage, same code, different results.
