No need; phones use sensor fusion these days. Wifi, ble, 4G/5G base stations, signals, etc. it's all taken into account. Which is why you can get accurate position in a lot of places where you definitely don't have any line of sight to any GPS satellites. Some of the more recent wifi standards also have some positioning features.
Early Android dev had a guide on how devs could pick the best location from various sources individually, and it was massive pain with dubious results.
