Sooooo I am an android NooB. I got a Verizon Gnex on launch day do replace my Palm Pre+. My question is: "where are my cell signal bars?" I don't know if it is an Android thing, or a 4G thing, or a me being an idioit thing; but I only seem to have data signal strength, listed as (3G/4G) and blue bars. But how do I know what strength cell signal I am getting? I have very good Verizon coverage in my area, but the other day I had quite a few dropped calls, which I NEVER get in almost 10 years of service. I went to check my bars I I didn't see them. Please tell me what I am missing...
