Okay, so I know there are already some threads about this, but i tried all the suggestions in those and nothing worked. The problem is that the GPS doesn't work quite right. For example, when I try to use google maps, it successfully locates me, but when I try to navigate somewhere it just says "searching for gps" and then never moves. I have tried changing location settings, resetting the A-GPS data, and clearing the cache partition. Is there anything else I can try or is it a hardware problem? By the way, it is a "certified" used galaxy s5 that I got from verizon (SM-G900V). I got the phone about a week ago, but I hadn't tried using gps until recently. As far as I know, it has never worked since I have had the phone.
