If GPIO 36 is not connected and not pulled up or down, the analog value on it will be indeterminate and can indeed be influenced by random stuff like a nearby GPIO. Thanks for hint! bad chip connection to pulled-up pin (i tested it, and voltmeter on resister pad showed proper value 3.3V), can lead ...

I have same problem) I have custom pcb with esp32 pico d4, and I use gpio34, gpio36, gpio39 with pull-up resistors, and gpio36 doesn't work :? I tried to read analog data and i see that grpio36 has some small value, but whan I push gpio34 button, gpio36 also became 0. have you solved your problem? e...
