Okay, so I know a lot of people are saying they have not had the problem at all, and others are saying they ALWAYS have it. I had thought the people who never have it might have gotten a phone that isn't affected for whatever reason. Some people have guessed it is based on signal issues, but one person tried it directly under a cell tower and still had it happen. So I have a new theory: I think the problem is definitely the phone, but it also has to do with the TOWERS. I think some towers respond okay to the phone, or compensate, while others don't. I'm not saying the phone isn't doing something weird, just that certain towers cause a loss of signal and others don't. Here is why I think so.... I have about 4 to 5 bars in my home office. I can make the phone go to 1 or 0 bars EVERY TIME I bridge the two antennas, even barely touching it with one finger. BUT, I just went to a busier part of town tonight and tried it, and no matter how much I gripped it or touched it, I could not get it to go lower than 5 bars. Obviously, the signal is stronger in this area, but as I said, someone had tried this standing directly under a tower, and was still able to do it. I think that if I found the tower near my house, I could probably get it to lose signal, but no matter what I do, I can not get it to lose signal in the busy part of town. It could even have something to do with towers that overlap? Maybe it is able to switch to another tower and not lose signal? What do you guys think?
