I've been having some problems (yes, I know about Samsung's rep with Antennas) with missed/dropped calls on my Verizon S3 (never had problems with my other phones - Dinc 2, Palm Pixi or LG Decoy (feature phone)). I finally figured the problem might be with the rollout of LTE in my small town. I've been seeing intermittent 4G LTE signals for the last couple of months (pretty much the entire time I've had the S3) but the speeds were slow. I finally decided to use Phone Info (from the app store) to switch off the LTE Radio and use CDMA (auto PRL) and my signal has improved by at least 20 db in practically every place I check it. I believe it could be because the LTE is not fully rolled out (supposed to be Oct 16 according to the local Verizon rep) and the phone is having trouble switching between CDMA, LTE, and EVDO. If anyone has any further thoughts on this please let me know because making and receiving phone calls is still important to me (I know, I'm a small minority). For now, until the full rollout of LTE in my town is official and turned on I'm going to leave the LTE radio off (by the way, I went to a town that has a full deployment and got 10-15 up and 10 down).
