Actually I am seeing or should I say reading other people post about IPhone 6 having issue with drop calls. However going to a different still might not fix the issue. As to say it's a carrier issue or network any other carrier might not have good network in this area so me going somewhere might result in me still having the same issue. There many problems with the IOS 8 and this might be a phone issue if I'm not the only whose having the same issue with drop calls. I didn't have no issue with drop calls in my android device nor my iPhone 5 and iPhone 5s so just maybe it might be a phone issue.
It's not a phone issue. The iPhone doesn't have a reception problem...nor is there anything related to iOS 8 that would even be relevant to your situation. You have a network issue...and not only that, but you don't even remember what you posted only a few hours ago...where you said you were having problems with the other devices so you upgraded...and now you're saying you didn't have issues with them? Which is it?
Bottom line, no amount of trading your phone in is going to fix a problem with the carriers network...your options are simple...switch carriers, move or go back to one of those devices you supposedly did or did not have reception problems with (since your own story has bounced all over the place).
Truth be told, in my experience and my wife's experience, we're getting BETTER reception with the iPhone 6 and 6 Plus. In areas where there were reception "holes" around Atlanta and previous models would lose reception or have reception degradation, the iPhone 6 and 6 Plus have been flawless.
Will everyone have the same experience? Certainly not...but if there was a true reception PROBLEM with the hardware itself, you'd see MASSIVE reports of the issue, and Apple would have addressed it. Instead, you are reading people who are having spotty reception issues with their specific carrier network, and like you, want to blame the device instead of considering a change that might actually work.
I mean you can keep thinking it's the phone and trade it in 100 more times...it's not wasting anyone's time but your own. We're simply trying to guide you with some logic, but hey...logic isn't for everyone I suppose.
