Motorola Droid Razr :: Doesn't Always Receive Calls

I've been using the phone for about two weeks now. In this time I've gotten a few text messages to the affect of, "I just called, why didn't you answer?" or when I call someone, they comment on how long it took for me to return their call. Piecing the feedback together, it seems that the phone doesn't always receive the call and ring. The person who is placing the call hears a dial tone, etc... and has no indication the call isn't ringing on my end. One time this occured, a voice mail was left and I received the voice mail right away. However, if no voicemail is left, I get no indication a call should have been received (no missed calls). The frequency of occurance is fairly hit and miss, besides, you can't prove someone didn't just call you .

I've experienced this on some other verizon phones of multiple brands (before smart phone times), and tend to think it has something to do with the software interactions between the carrier and platform, or perhaps the quality of antenna and how the software handles marginal signal. In the past, the only remedy I found was to change phones, but software pushes weren't as prevalent in those times.... Note, I've been a verizon customer since the dawn of time, so the carrier is a constant variable here. This phone was an upgrade from the Motorola Droid 1, and I didn't experience this problem (in the same locations) with this phone. For what it's worth, around town and at home I have a full 5 bars of signal strength, though I understand the bars are just a function of software.

I have also experienced some data drop out issues on 3G (patiently waiting for verizon to flip the LTE switch on) when heavily managing the wi-fi radio via the smart actions. There seem to be a few other complaints on the forums of similiar behavior. Changing the smart actions to have the wifi radio enabled most of the time seems to have helped with this issue, so I don't beleive it is related, but you never know..
