Has anybody checked the GPS accuracy on the S4 yet? The GPS on my GNex was one of the very few complaints I have with the phone, and I was hoping that Sammy put a better GPS chip in the S4. I occasionally use my phone for geocaching and obviously the more accurate the better. The easiest way to test it is to launch Google Maps, turn on the satellite layer, zoom in as far as you an, then stand by a visible landmark (like the corner of your driveway or something). How close does it plot you? Do you stay in one spot or does it jump around a lot? Thanks!
