What happened to the real time tracking of friends in Latitude? The feature used to be there, but I cant find it anymore
According tho this post, that feature was removed as of version 5.10 of Google Maps app because it was never properly working.
You can just press "refresh"-- and it will really give you second-by-second changes so long as the person you're looking at has their GPS on.
If location is set to "Network"- then it only updates when they change towers.
This is much more battery-efficient, it seems.
