for some reason, my 4s isnt gps tagging the photos im taking. it tagged the first 2 and hasnt tagged anymore since. i also have an old iphone photo cache saved on my computer that are all geotagged. i added one photo to my icloud and it pushed it to my phone. the gps location of that first pic showed up on my "places" tab. i added a few other pics and none of their locations showed up on the map. i have location services enabled and the camera on. any help or tips?
