AndroSensor says both work but auto brightness (auto dullness?) is useless and I triggered a keypad press while on a call...

see - thats exactly the point. The sensor does NOT work (on mine)
Proximity Sensor - will switch display off to avoid the keypress or other issues while on call when you are holding it to your face(ear). And re-enable display when moved away from the face
Autobrigh: measures ambient light and then adjusts brightness accordingly
you may have both confused?
check with AndroSensor:
proximity sensor - cover it with your hand (next to the front camera) and the values should change in AndroSensor - but they dont. neither does the display switch off during calls when detecting your face (actually just detecting "no light")
I will return my GN. I had enough.
