I found compasses don't work well in NYC either. My phone's compass is always wrong in NYC.

I really wish NYC would paint or engrave a N/S/E/W indicator on the sidewalk at every subway exit.

How strange. Why is that? They use a magnetometer.

Exactly - the steel everywhere in the infrastructure, buildings, and vehicles messes with the ambient magnetic field so the magnetometer can't consistently get a true field reading.
