I am having problems when trying to locate my device through certain applications that access my location through the internet. For instance, the Google Maps app always locates me, but if I use Google Maps on my phone thru the browser it cannot locate me this also happens often using Foursquare as well as Facebook. It will locate me only occasionally using gps, but almost never using my network location or wifi. Does anyone else find this happening to them on their GS3?
