I just picked up 2 of the Optimus v's at Target yesterday - one for my wife and one for myself. Love it so far. One strange thing I found is that side by side, full charge, same setup, one phone shows 5-6 bars and the other shows only 1. When I make or receive a call on that phone the signal suddenly jumps up to 5-6 bars, then back down when the call ends. Any ideas? Could it be a defective phone?
