I use waze and/or googlemaps to navigate. When I plan a route I 1st turn GPS on on my phone. Phone then always asks me to also turn on WIFI, but I always ignore this and leave it off because I thought its pointless if you're not actually connected to wifi. But does WIFI being on (without being actually connected) actually help pinpoint your location? How does it do that? My phone loses my location about 25% of the time, and I'm wondering if this is why? thanks!
