I found this out while I was attaching my location to the twitter app and noticed it attached the name of the highway that was 3 blocks away from my location. The GPS marker on the map showed the correct location though. I checked this on the maps app and indeed, any location I dropped a pin on will only recognize the main roads/ highways (those with yellow lines). It will never recognize the correct street. This is so frustrating. I tested this outdoors just so I can make sure I get accurate GPS signal. What's wrong here?
