Is there a way to check to see if Incredible2 antenna is working properly? Inside my house, my Dinc2 switches between 4 antennas in 4 cities ( I live in proximity to four corners of 4 cities..0.5 miles) Inside my house I have ZERO bars, nothing, that's notta, NONE, yet sometimes it registers as 3G. All of my calls in the past week have been dropping while in my house. This is not good since I don't have a land line. I'd like to verify this before I go to the drones that say "no" at the verizon store.
