So some people have stated that the proximity sensor issue on their phone is causing them to have a lot of dropped calls. I am now starting to believe that more and more to be the case and that most are not caused by the antenna reception. With the proximity issue, people are inadvertently hitting the mute or the end button without knowing therefore accidently ending calls. According to a lot of stats, the iPhone 4 quality has always been good or great even down to its last bar. But remember you are on AT&T, so dropped calls are bound to happen if you are in a bad area. But by fixing the proximity sensor issue, it can stop a lot people's dropped calls who are blaming it on the infamous antenna reception problem. Apple should really take a serious look at this as it could help dig themselves out the grave about the antenna problem. I am not having the proximity sensor problem, therefore I am not having any dropped calls and I am also in a good 3g area. To those who are having dropped calls, are you also having the proximity sensor issue?
