Dual-frequency in a smartphone is awesome, especially since, starting with Android Nougat, you're able to access raw GNSS measurements.

With this, your phone goes from being able to tell what street you're on, to where in a lane you are. 1-2 feet is the typical uncertainty, which is more than an order of magnitude better than what you get with a typical phone.
