All of sudden this week, everytime I am using maps, and press the button for my location, it searches and comes back with 'your location is temporarily unavailable' . this was a bad week for this to happen as I had to drive downtown and was looking for cutoffs from traffic. thought maybe when i was in my car just couldn't get a lock, but driving back from town before had the top down so clear view of sky, and ran gps status app, and only was getting 2 sats. Need at least 4. I run the phone with location only on gps, not triangulation from cell towers, i don't like the google note saying they are getting info from me even when i am not using maps if you turn on the cell location. I have hard reset the phone, no difference. Is there another program to check on my gps , or is the gps chipset bad and i need a new phone? Thanks for any advice.
