So, I'm wondering about this issue I have recently experienced. With the iPhone 6 came Verizon announcing that LTE voice is now live. I've had some issues with Verizon's LTE voice since then, however. I'm haven't pinpointed the issue, but my theory is that your call is much, much more likely to drop when on an LTE call versus a 1X call. While (to my knowledge) the LTE call should automatically default to a 1X call when cell service goes from 1 bar to 0 bars, for example, it seems that this transition process switching over from LTE to CDMA is very glitchy and often times causes a dropped call. I have always had bad service in my bedroom (1-2 bars max), yet I was able to make 1X calls with no issue anytime. However, since receiving my new iPhone 6 on Verizon, it seems that my dropped calls have become so frequent that it's concerning to me. I am sure it is a software issue, but it is a cellPHONE and I hope Verizon fixes this issue quickly as to make their new LTE voice relevant.
