So heres my biggest problem. I can be on the phone going on Facebook or something using the internet just fine. The next second the 4G is gone. The 4G symbol shows no activity in terms of downloading. Anything I try to do that uses data doesn't work. No FB, no Weather, no stock updates. This lasts sometimes for a couple of seconds to a couple of minutes (at that point I have to turn the phone on and off). It happens even when I am standing in the same place for a long period of time and have been on the phone with no problem. It's really annoying.
