I got my GSIII just a couple days ago and was stoked to finally be able to use 4g, but when I got home, of course, I could only pick up 3g. So, I was driving by all star sports on the west side and decided to stop to test the 4g because I know that a tower is right there. Worked like a charm. So then I decided to see how long I could hold on to the 4g signal as I made my way home. Determined to not give my phone a chance to let it go I did constant speed tests until I made it home (13th and West area) and was pleasantly surprised when I made it home and was still getting down speeds of 12mbps and up speeds of 8mbps. Of course this didn't last long... as soon as I tried to do something else with my phone it went right back to 3g... This makes me think that I might be able to get 4g at home, but for some reason my phone is switching to 3g... perhaps the 3g signal is way stronger so it thinks that will be better? I don't know...
I figured all the experts were here so I wanted to ask for some opinions on this... Checking on the sprint coverage map it looks like the 13th and West area should be well covered with 4g... Any info on this would be greatly appreciated.
