I'm having the very same issue, and have gone to both Samsung and AT&T for resolution, with no success. I, too, have had trouble with anyone believing that everyone else in my home, and in my office, with other phones, gets 4-5 bars, while I get 0-1. They say it's a problem with the antenna in my particular phone, but are unwilling to do anything but replace it with a refurbished one. After reading this forum, I'm not sure that will work either. As one of the hottest phone on the market, how is this possible?
