I've had the Vibrant for a couple days now. Unfortunately, I have a VERY weak 3G signal and my call quality really isn't that great. In my house, when I hold my phone right next to my Dad's Nuron, he has a full 3G signal while I have 0 bars. That is frustrating to see. The phone isn't incapable of having 3G signal, when I travel outside of my neighborhood it usually has a very strong signal. It seems that whenever I am around a lot of trees or in buildings, the signal is very weak. I mostly just have an Edge signal. Also, the call quality is terrible. I don't think it has to do with the signal because even when I have full 3G bars, it still sucks.... Is it possible I got a dud of a phone? I still have 14 days to exchange if that's the case.
